Provedor de dados: 21
Autores: Gutiérrez, S.; Diago, M.P; Fernandez-Novales, J.; Tardaguila, J.
The high impact of irrigation in crop quality and yield in grapevine makes the development of plant water status monitoring systems an essential issue in the context of sustainable viticulture. This study presents an on-the-go approach for the estimation of vineyard water status using thermal imaging and machine learning. The experiments were conducted during seven different weeks from July to September in season 2016. A thermal camera was embedded on an all-terrain vehicle moving at 5 km/h to take on-the-go thermal images of the vineyard canopy at 1.2 m of distance and 1.0 m from the ground. The two sides of the canopy were measured for the development of side-specific and global models. Stem water potential was acquired and used as reference method....

Long-term stability and mineralisation rate of compost is influenced by timing of nutrient application during composting of plant residues
Provedor de dados: 21
Autores: Dresbøll, Dorte Bodin; Magid, Jakob; Thorup-Kristensen, Kristian.
The long-term nitrogen mineralization and stability of compost based on easily available plant residues was examined. Four different composts were prepared from wheat straw and clover-grass hay, one treatment receiving all material initially (100/0), two treatments where addition of 75% of the clover-grass was postponed for 3 weeks (75/25,3w) respectively 8 weeks (75/25,8w) and one treatment receiving only 25% of the clover-grass added to the other treatments (25/0). Mineralization and stability of the compost was followed for 24 weeks in leaching tubes, leached regularly by 0.01 M CaCl2. Postponing the addition of the clover-grass hay for 3 weeks (75/25,3w) during composting had a significant effect on the N mineralization rate leading to more mineralised...

Assessment of selenium mineralization and availability from catch crops
Provedor de dados: 21
Autores: Stavridou, Eleftheria; Thorup-Kristensen, Kristian; Young, Scott D.
Selenium (Se) release from four plant species (Indian mustard, fodder radish, Italian ryegrass and hairy vetch) was measured under controlled leaching conditions and in a pot incubation experiment as part of a study of the potential for using these plant species as Se catch crops. Catch crops may reduce Se leaching and, by subsequent release of Se from the plant material, increase the available Se for succeeding crops. Plants grown both without and with Se addition (250 g Se/ha) were tested. In the leaching experiment, frozen plant material was incorporated into soil columns and incubated at room temperature for up to 19 weeks. The results showed that Se concentrations in the leachate were higher when Se-enriched plant material was incorporated in the...

Carbon footprints of organic dairying in six European countries—real farm data analysis
Provedor de dados: 21
Autores: Hietala, Sanna Maria; Smith, Laurence; Knudsen, Marie Trydeman; Kurpa, Sirpa; Padel, Susanne; Hermansen, John E.
Dairy farming is the largest agricultural contributor to greenhouse gas emissions in Europe. In this study, the carbon footprint of organic dairying was evaluated by means of a life cycle assessment, based on real farm data from six European countries: Austria, Belgium, Denmark, Finland, Italy and United Kingdom.   A total of 34 farms were analysed. The assessment was carried out using an attributional approach with system boundaries from cradle to farm gate. In relation to dairy production, a functional unit of 1 kg of energy corrected milk was used. The results gave an average of 1.32 kg CO2 equivalents per kilogramme of energy-corrected milk with standard deviation of 0.22, which is consistent with recent studies. The main contributor to this is enteric...

In einem im Jahr 2003 unter überdurchschnittlich trockenen und warmen Bedingungen durchgeführten Weideversuch mit drei Gruppen von jeweils 20 Jungrindern wurde die Wirkung einer biologischen (Duddingtonia flagrans) und einer medikamentösen (Paratect Flex-Bolus; PFB) Kontrollmethode gegen Befall mit Magen-Darm-Nematoden (MDN) gegenüber einer unbehandelten Kontrollgruppe verglichen. Die meteorologischen Bedingungen führten über direkte (reduzierter Übergang der Infektionsstadien auf die Vegetation; erhöhte Absterberate) und indirekte Faktoren (geringere Besatzdichte, Zufütterung) zu einer deutlichen Verringerung des Infektionsdruckes auf den Versuchsweiden. Daher erwiesen sich weder die medikamentöse noch die biologische Prophylaxestrategie als erforderlich,...

Agro-ecology: beyond food
Provedor de dados: 21
Autores: Félix, Georges F.; Timmermann, Cristian.
Some may view indigenous communities as being conservative and backwards. However, the Kabekwa in Costa Rica show that such communities can be adaptable and innovative. In response to changing circumstances, this community has been adapting its farming practices constantly, benefiting from it in multiple ways.  In this case study we show some of the additional advantages agro-ecology provides to farmers beside food. Using the concept of meaningful work we explore how knowledge-intensive farming stimulates the development of skills, improves self-determination and provides incentives for younger generations to work on the land.

Effects of Organic and Conventional Growth Systems on the Content of Flavonoids in Onions and Phenolic Acids in Carrots and Potatoes
Provedor de dados: 21
Autores: Søltoft, Malene; Nielsen, J.; Laursen, Kristian Holst; Husted, Søren; Halekoh, Ulrich; Knuthsen, Pia.
The demand for organic food products is steadily increasing partly due to the expected health benefits of organic food consumption. Polyphenols, such as flavonoids and phenolic acids, are a group of secondary plant metabolites with presumably beneficial health effects, and contents in plants are affected by, for example, plant nutrient availability, climate, pathogen infection, and pest attack. In the current study, onions, carrots, and potatoes were cultivated in two-year field trials in three different geographical locations, comprising one conventional and two organic agricultural systems. The contents of flavonoids and phenolic acids in plants were analyzed by pressurized liquid extraction and high-performance liquid chromatography−ultraviolet...

Impact of animal health and welfare planning on medicine use, herd health and production in European organic dairy farms
Provedor de dados: 21
Autores: Ivemeyer, Silvia; Smolders, G.; Brinkmann, J.; Gratzer, E.; Hansen, B.; Henriksen, Britt I. F.; Huber, J.; Leeb, C.; March, S.; Mejdell, C.; Nicholas, P; Roderick, S; Stöger, E.; Vaarst, M.; Whistance, L.K.; Winckler, C.; Walkenhorst, Dr. Michael.
A reduction of medicine use (udder treatments, metabolic treatments and total number of treatments) in organic dairy herds was achieved within a time period of one year under different conditions across seven European countries. At the same time an improvement of udder health (SCS) and a stable situation in other health areas (metabolic disorders, fertility) was found, however regardless of the focus area in the AHWP. The AHWP process which was implemented on the farms may therefore be regarded a feasible approach to minimise medicine use without impairment of health, longevity and productivity under most European organic dairy farming conditions. However, further long-term studies are necessary to investigate effects of specific advice included in herd...

Organic Dairy Production - A Review
Provedor de dados: 21
Autores: Nicholas, Phillipa; Padel, Susanne; Cuttle, S P; Fowler, S M; Hovi, M; Lampkin, N H; Weller, R F.
Organic farming aims to create an integrated, humane, environmentally and economically sustainable agricultural system.  For organic dairy systems, the fulfilment of these aims requires the understanding and integration of a number of systems components including land use (mixed or dairy only) and stocking rate; grassland and forage production (including quantity and quality); potential milk yield (and milk quality); animal nutrition (largely farm based) and health; environmental sustainability such as farm nutrient balance; the financial status of the farm (including enterprise performance, fixed costs and labour use and farm income and profit) and finally the policy environment in which organic dairy systems operate.  This review discusses worldwide...

Quality and safety aspects of organic and low-input food processing: Results of a Delphi survey from an expert consultation in 13 European countries
Provedor de dados: 21
Autores: Kretzschmar, Ursula; Schmid, Otto.
Organic food-processing standards generally prohibit the use of synthetic chemicals, many preservatives and other food additives that are widely used in the processing of conventional foods. However, there are frequent discussions about the underlying rationales, principles and criteria used to allow some processing methods and additives but other ones not. Consumers of low-input and organic food have specific expectations regarding quality characteristics of processed food. Organic processed products should therefore be sustainable and fulfil consumers’ expectations as much as possible. Our study reviewed current approaches and concepts in organic food processing, based on the results of a literature survey and a two-step Delphi expert survey focusing on...

Autores: Su, Guosheng; Kjaer, Jørgen B.; Sørensen, Poul.
Variance components and selection response for feather pecking behaviour were studied by analysing the data from a divergent selection experiment. An investigation show that a Box-Cox transformation with power =-0.2 made the data be approximately normally distributed and fit best by the given model. Variance components and selection response were estimated using Bayesian analysis with Gibbs sampling technique. The total variation was rather large for the two traits in both low feather pecking line (LP) and high feather pecking line (HP). The standard deviation was about three times as large as the mean in the observed scale, and about the same value as the mean in the transformed scale. Based on the mean of marginal posterior distribution, in the Box-Cox...

Growth and survival of the pearl oyster Pteria hirundo (L.,1758) in an intermediate stage of culture in Santa Catarina, Brazil.
Provedor de dados: 21
Autores: Albuquerque, MCP; Alves, R; Zanandrea, ACV; Ferreira, J F; Melo, CMR; Magalhães, ARM.
There are no records in Brazil for the culture of Pteridae family oysters, genus Pteria and Pinctada. The intermediate culture can be considered one of the critical stages during the oyster farming. The changes in life conditions from a semi-closed environment provided by the collector to the structures utilized for the growth represents a considerable stress factor to which the animals are subjected. The goal of the present study was to evaluate the growth and survival of the pearl oyster Pteria hirundo (Linnaeus, 1758) kept in intermediate lanterns. Seeds of P. hirundo, obtained through larviculture carried out at the Marine Molluscs Laboratory (UFSC), southern Brazil were detached from the collectors, transferred and kept in an intermediate culture...

Hvordan kan sædskiftet indrettes så den økologiske kornproduktion øges uden at bæredygtigheden mindskes? Dette centrale spørgsmål belyses med resultater fra et økologisk sædskifteforsøg, der i 1996/97 blev anlagt på tre lokaliteter i Danmark. Da forsyningen med kvælstof (N) kan være meget kritisk i økologisk kornproduktion blev forsøget designet med fokus på dyrkningsmæssige faktorer der har indflydelse på N-forsyningen. Tre faktorer blev undersøgt:     1) Betydning af andel af N-fikserende afgrøder i sædskiftet   2) Betydning af efterafgrøder    3) Betydning af tilførsel af husdyrgødning.     Der blev målt udbytter, udvaskning af næringsstoffer samt forekomst af ukrudt.     Forsøget demonstrerer vigtigheden af at undersøge dyrkningsfaktorer i en...

Towards a systemic research methodology in agriculture: Rethinking the role of values in science
Provedor de dados: 21
Autores: Alrøe, Hugo Fjelsted; Kristensen, Erik Steen.
The recent drastic development of agriculture, together with the growing societal interest in agricultural practices and their consequences, pose a challenge to agricultural science. There is a need for rethinking the general methodology of agricultural research. This paper takes some steps towards developing a systemic research methodology that can meet this challenge – a general self-reflexive methodology that forms a basis for doing holistic or (with a better term) wholeness-oriented research and provides appropriate criteria of scientific quality.   From a philosophy of research perspective, science is seen as an interactive learning process with both a cognitive and a social communicative aspect. This means, first of all, that science plays a role in...

Autores: Katakam, Kiran Kumar; Mejer, Helena; Dalsgaard, Anders; Kyyvsgaard, Niels Christian; Thamsborg, Stig Milan.
tEggs of Ascaris suum from pigs are highly resistant and commonly used as a conservativeindicator of pathogen inactivation during slurry storage. Eggs of Ascaridia galli, the poultryascarid, are also known to be highly resistant but the suitability as an indicator of pathogeninactivation has never been tested. Pig slurry has to be stored for several months to inac-tivate pathogens but chemical treatment of slurry may reduce this time. The suitability ofA. galli as an indicator of slurry sanitation was tested by comparing the survival of eggsof A. suum and A. galli in pig slurry. In addition, the effect of urea treatment on inactiva-tion of ascarid eggs in relation to storage time was also tested. Nylon bags with 10,000eggs of either species were placed in...

Cotton-basil intercropping: effects on pests, yields and economical parameters in an organic field in Fayoum, Egypt
Provedor de dados: 21
Autores: Schader, Christian; Zaller, Johann G; Köpke, Ulrich.
In many countries, cotton is traditionally intercropped with other plants in order to increase yields and to control pests. We tested the effects of intercropping cotton (Gossypium barbadense L.) and basil (Ocimum basilicum L.) during one field season on pest infestation, yields, and economical parameters in the Governorate of Fayoum, Egypt. Basil, which is known for its repellent effect on various insect pests, was mixed with cotton in three different intercropping rates (no, medium and high basil area fraction) and two row distances (60 and 90 cm) using a substitutive design with four replicates. Compared with the non-intercropped plots, cotton-basil intercropping significantly reduced total pest infestation and led to a 50% reduced abundance of the pink...

Sheep grazing vs. cutting: regeneration and soil nutrient exploitation of the grassland weed Rumex obtusifolius
Provedor de dados: 21
Autores: Zaller, Johann G.
Broad-leaved dock (Rumex obtusifolius L., Polygonaceae) is an agronomically  important perennial weed causing decreases in pasture yields and fodder quality.  Non-chemical control measures for dock are often limited to frequent pulling and  cutting, additionally it is usually avoided by grazing animals. Here, the regeneration of  R. obtusifolius in a Rumex-infested grassland grazed by a sheep breed that explicitly  feeds on dock (Ovis aries L. cv. East Prussian Skudden) was compared to cutting.  Therefore, regeneration of 90 R. obtusifolius plants of three different size classes was  monitored in three plots during three grazing and cutting cycles. Plant height and  number of fruit-stands of regrown R. obtusifolius was significantly lower, number of...

Agricultura e biodiversidade nas ciências sociais brasileiras: alimentando a comunicação entre ciência e políticas públicas.
Provedor de dados: 21
Autores: Carneiro, Maria José; Danton, Thais.
O presente artigo decorre de uma reflexão sustentada em dois pressupostos: a) que as ciências e, em particular, as sociais, podem contribuir para informar as tomadas de decisão e a formulação de políticas públicas visando a melhoria da vida das pessoas no planeta e b) que o papel da agricultura na conservação da biodiversidade é uma questão atual de extrema relevância e que merece ser aprofundada. A relação entre a agricultura e a biodiversidade tem sido objeto de questionamentos recentes na sociedade e no campo das políticas públicas. Contudo, se os estudos relacionados à biodiversidade e à agricultura, separadamente, têm observado um considerável crescimento no Brasil, poucos são os investimentos de pesquisa sobre a relação entre esses dois grandes...

The work aims to investigate the effects of different soil management strategies on carbon sequestration and total nitrogen in areas of vineyards suffering from loss of soil functionality. Treatments, selected for inter-row management, to re-install soil functionality were based on compost or other organic amendments (COMP), green manure (GM), and dry mulching (DM) strategies using winter legumes and cereals. Cover crops were seeded in fall and mown in late spring, leaved in the ground for mulching in DM or incorporated into the uppermost soil layers in GM. Such approaches were investigated in six vineyards in Italy, six in France, and two vineyards in Slovenia and Turkey.     The results showed that COMP significantly increased total organic carbon (TOC)...

Autores: Bezerra,  Vinícius Pereira.
O Projeto de Lei nº 1.876/99, tramitando atualmente no Senado Federal, é um substitutivo do Código Florestal Brasileiro. A proposta de novo Código Florestal, de autoria do deputado federal Aldo Rebelo (PCdoB-SP), segundo a crítica da comunidade científica e de variados movimentos sociais, trará impactos profundamente danosos à biodiversidade dos ecossistemas brasileiros e, por conseguinte, afetará as populações humanas. No presente artigo, o mencionado Projeto de Lei é analisado, contrastando-o com o paradigma da Educação do Campo, de modo a evidenciarmos que ambos são antíteses inconciliáveis. Destarte, caso o PL seja aprovado e sancionado, representará profundo embargo à consolidação da Educação do Campo.

Contamination of Farms by Genetically Modified Organisms (GMOs): Options for Compensation
Provedor de dados: 21
Autores: Paull, John.
There is no satisfactory legal remedy for farmers in Australia whose farm has been contaminated by genetically modified (GM) material. This is a deficiency of Australia’s Gene Technology Act 2000 and it has not been remedied. In the Marsh v Baxter case (2010-2016) an organic farm in Western Australia (WA) was contaminated with GM canola from a neighbouring farm. The organic farm lost its certification (along with the price premium for organic produce). The organic farmer (Marsh) sued the GM farmer (Baxter) for the agreed damages of A$85,000. The case was lost in the WA Supreme Court, then in the Court of Appeal, and finally it was rejected by the High Court of Australia. The legal fees were in the order of A$2,000,000, which is quite disproportionate to...

Autores: Hagel, I.
Einleitung:   Biologisch-dynamisch angebaute Möhren (Markenzeichen demeter) werden teilweise zur Saftherstellung verwendet. Einige Verarbeiter garantieren im Möhrensaft bestimmte Mindest- und Höchstwerte für die Mineralstoffe Kalium (K) und Natrium (Na). Wie berichtet wurde, erfüllten einige Partien der angemeldeten Möhren diese Voraussetzung nicht in gewünschtem Maße. In diesen Fällen ist das Qualitätsziel des Verarbeiters und somit auch der Verkauf der Möhren an diesen gefährdet. Aus diesem Grund wurde im Jahre 1993/94 ein Projekt durchgeführt um einen besseren Überblick über die Mineralstoffgehalte von Möhren aus biologisch-dynamischem Anbau zu bekommen.    41 Möhrenproben und 36 Bodenproben der Ernte 1993 wurden untersucht.

Autores: Lukas, Kathrin; Innerebner, Gerd; Kelderer, Markus; Finckh, Maria R.; Hohmann, Pierre.
The six products, Armicarb, Vitisan, lime sulphur, Caso, Calce Fiocco and Ulmasud were tested for their ability to control downy mildew (Plasmopara viticola) on grapevine (Vitis vinifera) in order to find effective alternatives to copper, a heavy metal that is commonly used as a fungicide in organic viticulture. Each product was applied to potted grapevines at i) 40°h (degree hours) and ii) 80°h after inoculation (ai) of the pathogen. These so-called stop-sprays were tested on plants that received two different P. viticola inoculum rates. The formulated potassium bicarbonate product Armicarb and lime sulphur reduced disease incidence and severity similar to or better than the copper hydroxide treatment.

Comparison of Polyacetylene Content in Organically and  Conventionally Grown Carrots Using a Fast Ultrasonic Liquid Extraction Method
Provedor de dados: 21
Autores: Søltoft, Malene; Eriksen, M.R.; Träger, A.W.B.; Nielsen, J.; Laursen, Kristian Holst; Husted, Søren; Halekoh, Ulrich; Knuthsen, Pia.
A rapid and sensitive analytical method for quantification  of polyacetylenes in carrot roots was developed. The traditional extraction method (stirring) was compared to a new ultrasonic liquid processor (ULP)-based methodology using high-performance liquid chromatography−ultraviolet (HPLC−UV) and mass spectrometry (MS) for identification and quantification of three polyacetylenes. ULP was superior because a significant reduction in extraction time and improved extraction efficiencies were obtained. After optimization, the ULP method showed good selectivity, precision [relative standard deviations (RSDs) of 2.3−3.6%], and recovery (93% of falcarindiol) of the polyacetylenes. The applicability of the method was documented by comparative analyses of carrots...

Ganzheitlichkeit in der Forschung zum Öko-Landbau
Provedor de dados: 21
Autores: Leiber, Florian.
Dem Anspruch gerecht zu werden, „ganzheitlich“ forschen zu wollen/zu sollen, ist mitunter schwierig. Dabei muss es nicht immer um ein „Ganz-Lassen“ gehen. Die Aufgabe besteht vielleicht eher in einem „Ganz-Denken“. Das Herstellen von Sinnbezügen zwischen den (beispielsweise durch Analytik sichtbar gewordenen) Teilen lässt uns das „Ganze“ oft erst erkennen und somit auch darstellen und vermitteln. Dies ist ein kreativer Akt des individuellen Denkens, aber gerade durch diesen könnte sich die Forschung für den Öko-Landbau auszeichnen und ein wirkliches Gegengewicht zum wissenschaftlichen  Reduktionismus schaffen.

Emergence time and skin melanin spot patterns do not correlate with growth performance, social competitive ability or stress response in farmed rainbow trout
Provedor de dados: 21
Autores: Gesto, Manuel; Skov, Peter V.; Jokumsen, Alfred.
In wild salmonid fish, specific individual behavioral traits have been correlated with the timing of fry emergence from their gravel spawning nests; Early emerging fish display more aggressive behavior and have a higher probability of becoming socially dominant, compared to fish that emerge at a later stage. Apart from aggression and dominance, other behavioral and metabolic traits, such as boldness, metabolic rate, or growth, have also been linked to emergence time. Altogether, the traits of early- and late-emerging fish resemble those of the proactive and reactive stress-coping style, respectively. As proactive fish are considered more resilient to stress, it may be desirable to select these for aquaculture production. However, it is currently unclear to...

Complex agroforestry systems against biotic homogenization: The case of plants in the herbaceous stratum of cocoa production systems
Provedor de dados: 21
Autores: Marconi, Luis; Armengot, Laura.
In addition to their potential against deforestation and climate change, agroforestry systems may have a relevant role in biodiversity conservation. In this sense, not only species richness per se, but also community composition, including the distribution range of the species, should be considered. The latter is especially relevant in the current context of biotic homogenization, where the presence of geographically widely distributed species is increasingly frequent in detriment of native species.    By studying plant species of the herbaceous stratum of cacao production systems, we can evaluate, at a narrow local scale (&gt;10 ha), the potential role of agroforestry systems and management intensity in diversity conservation and against biotic...

Autores: Retz, S.K.; Porley, V.E.; von Gersdorff, G.J.E; Hensel, O.; Crichton, S.O.J.; Sturm, B.
The quality of dried meat products and the drying kinetics significantly depends on the status of the raw material going into the drying process. The aim of this study was the determination of the impact of meat status (fresh, mature, frozen-thawed) on the drying kinetics and the resulting quality in terms of colour changes and spectrally deductible information.  Drying tests were conducted using meat from organically raised bulls. In fresh meat, freezing leads to a decrease of the drying rate, whilst for matured meat the opposite is true. Aging and freezing have little effect on the end product quality in terms of final product colour. However, water content can be detected hyperspectrally and resolved spatially for all stages of the pro-cess. With...

No Brasil, as políticas públicas para o espaço rural sempre tenderam a priorizar a agricultura patronal, em detrimento dos agricultores familiares. Todavia, os estudos realizados pelos órgãos FAO - INCRA deram subsídio para a criação do Programa Nacional de Fortalecimento da Agricultura Familiar (PRONAF), resultando em um novo direcionamento dos investimentos públicos, os quais passaram a contemplar o segmento dos agricultores familiares. Entende-se o PRONAF como uma política não-compensatória, que, apesar de seus problemas, tem contribuído de fato para mudanças e melhorias no espaço agrário brasileiro.

“The illusion of plenty” and “poverty in plenty” are notions that Lord Northbourne raised in his manifesto of organic agriculture, Look to the Land. At the launch of this new journal, Plenty, it is timely to revisit Northbourne’s reflections on the topic.    In the current epidemic of obesity, where 25% of Australians, 23% of British, and 34% of Americans are obese, we witness the manifestations of Northbourne’s notions of “the illusion of plenty” and “poverty in plenty”. We live in a time when the super obese may be extricated from their homes by a demolition team knocking down walls, may be transported to hospital in specially reinforced fat-mobile ambulances, and may be CT scanned in machines that are otherwise used for large zoo animals .

On-Farm nutrient balance assessment to improve nutrient management on organic dairy farms
Provedor de dados: 21
Autores: Taube, Friedhelm; Pötsch, E.M.
A survey is presented on the impact of different intensities of grassland management related to nutrient balances and their assessment. With special reference to data from Austria and Germany, it is postulated that on-farm nutrient balance assessment is a valuable tool for identifying deficits in efficiency of nutrient use in the soil-plant-animal system. Farm gate balances can be used as indicators for Codes of Good Agricultural Practice in Europe, if input/output parameters and calculations are standardised and if acceptable surpluses are regionally validated.

Anaerobic digestion of residual liquid effluent (brown juice) from a green biorefinery
Provedor de dados: 21
Autores: Martinez, EJ; Mirolucci, Federico; Gomez, X; Molinuevo-Salces, Beatriz; Uellendahl, Hinrich.
This work studied the anaerobic digestion of brown juice, a liquid residual stream generated from biomass fractionation in a green biorefinery. Biomethane potential batch tests and inhibition studies of brown juice were performed during continuous processing in an upflow anaerobic sludge blanket reactor. Prolongation of the lag phase in the batch tests with increasing substrate/inoculum ratio suggested initial inhibition, which was, however, overcome by adaptation. This was indicated by high final methane yields, which were close to the theoretical maximum of up to 500 L-CH4 kg-VS−1, achieved after 15 days for most of the set-ups. Reactor operation at the organic loading rate of 13.9 g-COD L−1 day−1 and hydraulic retention time of 3 days revealed methane...

Parasite problems in organic livestock and options for control
Provedor de dados: 21
Autores: Thamsborg, Stig Milan; Roepstorff, Allan.
ABSTRACT: Organic livestock production has increased dramatically in recent years in Europe and other parts of the world. The aim of producing livestock under more natural conditions has led to a reversion to primarily outdoor production systems and less intensive housing when indoor, more forage-based diets, and a reduced reliance on external inputs like antiparasiticides. These major changes in livestock production systems may potentially result in re-emergence (or emergence) of parasitic infections. The basic objective of this paper is to give an overview of the available information on parasitic problems in organic livestock production with a focus on northern temperate regions. Furthermore, options for control that target these problems and are...

Performance and diarrhoea in piglets following weaning at seven weeks of age: Challenge with E. coli O 149 and effect of dietary factors
Provedor de dados: 21
Autores: Sørensen, Martin T.; Vestergaard, Ellen-Margrethe; Jensen, Søren K.; Lauridsen, Charlotte; Højsgaard, Søren.
Four dietary factors (ad libitum versus feed restriction, control versus protein restriction at ad libitum feeding, control versus inclusion of lupine as a protein source at ad libitum feeding, and control versus extra vitamin E at ad libitum feeding) were tested in four separate experiments for the effect on diarrhoea. To introduce a diarrhoea-like condition, half of the piglets were challenged with an inoculation of an E. coli O 149 dose of 1 x 108 colony forming units on day two and three after weaning (day of weaning = day one). All piglets were susceptible since the dams were tested mono-zygotic susceptible to the attachment site of E. coli O 149 in the intestines. Each of the four experiments included 32 piglets from 4 sows. The design was 2 x 2...

Finger Millet Growth and Nutrient Uptake Is Improved in Intercropping With Pigeon Pea Through “Biofertilization” and “Bioirrigation” Mediated by Arbuscular Mycorrhizal Fungi and Plant Growth Promoting Rhizobacteria
Provedor de dados: 21
Autores: Saharan, Krishna; Schütz, Lukas; Kahmen, Ansgar; Wiemken, Andres; Boller, Thomas; Mathimaran, Natarajan.
Legume-cereal intercropping is well known in traditional dry land agriculture. Here, we tested whether finger millet, a shallow-rooted cereal, can profit from neighboring pigeon pea, a deep-rooted legume, in the presence of “biofertilization” with arbuscular mycorrhizal fungi (AMF) and plant growth-promoting rhizobacteria (PGPR), under drought conditions. We conducted a greenhouse experiment using compartmented microcosms. Pigeon pea was grown in a deep compartment with access to a moist substrate layer at the bottom, whereas finger millet was grown in a neighboring shallow compartment, separated by 25-µm nylon mesh, without access to the moist substrate layer. In the presence of a common mycorrhizal network (CMN), with or without PGPR, a drought condition...

Effects of farm heterogeneity and methods for upscaling on modelled nitrogen losses in agricultural landscapes
Provedor de dados: 21
Autores: Dalgaard, Tommy; Hutchings, Nicholas J.; Dragosits, U.; Olesen, J.E.; Kjeldsen, Chris; Drouet, J.L.; Cellier, P.
The aim of this study is to illustrate the importance of  farm scale heterogeneity on nitrogen (N) losses in  agricultural landscapes. Results are exemplified with a chain of N models calculating farm-N balances and distributing the N-surplus to N-losses (volatilisation, denitrification, leaching) and soil-N accumulation/release in a Danish landscape. Possible non-linearities in upscaling are assessed by comparing average model results based on (i) individual farm level calculations and (ii) averaged inputs at landscape level. Effects of the non-linearities that appear when scaling up from farm to landscape are demonstrated.  Especially in relation to ammonia losses the non-linearity between livestock density and N-loss is significant (p &gt; 0.999), with...

Spatial-temporal soil moisture dynamics under different cocoa production systems
Provedor de dados: 21
Autores: Niether, Wiebke; Schneidewind, Ulf; Armengot, Laura; Adamtey, Noah; Schneider, Monika; Gerold, Gerhard.
Soil moisture has high spatial and temporal variability, depending on topography, soil texture, vegetation and meteorological conditions. It influences many processes in the soil and supplies water to the vegetation. This is often a limiting factor in agricultural production.  Over an 18-month period, we measured soil moisture dynamics down to a depth of 70 cm in a long-term trial in Bolivia comprising six different land-use systems, i.e. cocoa monocultures and agroforestry systems, both under organic and conventional management, successional cocoa agroforestry systems and a natural fallow. Soil was heterogeneous over the area and in depth. We identified and separated two soil groups which differed in both, texture and soil water retention capacity....

Effect of lactid acid bacteria inoculants, formic acid, potassium sorbate and sodium benzoate on fermentation quality and aerobic stability of wilted grass silage
Provedor de dados: 21
Autores: Saarisalo, Eeva; Jalava, Taina; Skyttä, Eija; Haikara, Auli; Jaakkola, Seija.
The efficiency of a novel strain of lactic acid bacteria inoculant (Lactobacillus plantarum VTT E-78076, E76) on the fermentation quality of wilted silage was studied. Furthermore, the possibility to improve aerobic stability of silages by combining an inoculant and chemical preservatives was investigated. Two experiments were conducted with wilted timothy-meadow fescue herbage (dry matter 429 and 344 g kg-1) using six treatments. In experiment I, E76 (106 cfu g-1 fresh matter (FM)) was applied alone and in combination with sodium benzoate (0.3 g kg-1 grass FM) or low rate of formic acid (0.4 l t-1 FM). In experiment II, E76 and a commercial inoculant were applied alone and in combination with sodium benzoate. Untreated silage and formic acid (4 l t-1 FM)...

EU organic logo and its perception by consumers
Provedor de dados: 21
Autores: Zander, Katrin; Padel, Susanne; Zanoli, Raffaele.
Purpose  – With the introduction of the mandatory European Union (EU) organic logo for all organic food products in 2010, the European Commission aimed at fostering the internal organic food market. This needs consumers’ knowledge of the logo. According to earlier research consumers’ knowledge of the EU organic logo is low. Thus, the purpose of this paper is to elicit consumers’ attitudes towards organic certification and labelling and to develop recommendations on how to improve consumers’ knowledge of the EU organic logo.    Design/methodology/approach  – By means of an online survey with 3,000 participants in six European countries, knowledge of the logo and attitudes towards organic farming and European labelling, as well as organic food purchase...

The Soil Association and Australia: From Mother Earth to Eve Balfour
Provedor de dados: 21
Autores: Paull, John.
From its inception the Soil Association was linked with emerging organic thinking in Australia and New Zealand. When the Association was formed in 1946 two of its founder members were residents of Australia and New Zealand, there were already three like minded associations in the region, and the first issue of ‘Mother Earth’ included three articles from antipodean sources. Given this influence it is perhaps no surprise that in the late fifties the Association’s founder, Eve Balfour, spent a year visiting Australia and New Zealand – arriving an ambassador of the Soil Association, and leaving an ambassador for Australia.

Tomaten gehören zu den wichtigsten Gemüsen in Deutschland. Angebaut werden Tomaten im Klein- und Erwerbsgartenbau fast nur noch unter Glas oder Folie, weil im Freiland die Kraut- und Braunfäule (Phytophthora infestans (Mont.) de Bary) stark zugenommen hat. Sortensichtungen des Dreschflegel e.V. hatten seit 1996 gezeigt, dass Sorten mit interessanter Feldresistenz gefunden werden können. Ein Phytophthora-Schlüssel wurde entwickelt, um in Feldbeständen den Befall an Blatt, Stängel und Frucht zu dokumentieren. Durch mehrortige Sichtung konnten Sorten mit wichtigen agronomischen, morphologischen und phänologischen Eigenschaften für den Anbau im Freiland identifiziert werden. Die nicht-kommerzielle Saatgutarbeit hat dafür eine immense Bedeutung: Etwa 90% der...

Occurrence and importance of plant-parasitic nematodes in organic farming in Germany
Provedor de dados: 21
Autores: Hallmann, Johannes; Frankenberg, Andrea; Paffrath, Andreas; Schmidt, Harald.
In an attempt to evaluate the occurrence and economic importance of plant-parasitic nematodes in organic farming in Germany, a survey was conducted with the main emphasis on vegetable and cereal production systems. For vegetables, the survey included quantification and identification of plant-parasitic nematodes in soil samples and a questionnaire for growers querying production factors and damage levels. For cereals, the survey focused on quantification and identification of plant-parasitic nematodes in soil and plant samples. Overall, Pratylenchus and Tylenchorhynchus were the most prominent nematode genera under both production systems with an incidence of over 90% of the samples. Meloidogyne was detected in 51% of the samples in both systems. Other...

Environmental assessment of organic juice imported to Denmark: a case study on oranges (Citrus sinensis) from Brazil
Provedor de dados: 21
Autores: Knudsen, Marie Trydeman; Almeida, Gustavo Fonseca de; Langer, Vibeke; Abreu, Lucimar Santiago de; Halberg, Niels.
Growing global trade with organic products has given rise to a debate on the environmental impacts during both production and transport. Environmental hotspots of organic orange juice produced by smallholders in Brazil, processed and imported to Denmark were identified in a case study using a life cycle approach. Furthermore, small-scale organic orange production was compared with small-scale conventional and large-scale organic orange production in the case study area in Brazil.      Transport was the main contributor (57%) to the global warming potential of organic orange juice from small-scale farmers imported to Denmark, followed by the processing stage (29%), especially the truck transport of fresh oranges in Brazil and of reconstituted orange juice...

Effect of mycorrhizal inoculation and compost supply on growth and nutrient uptake of young leek plants grown on peat-based substrates
Provedor de dados: 21
Autores: Perner, Henrike; Schwarz, Dietmar; George, Eckhard.
Organic horticultural production systems often are characterized by the use of beneficial soil microorganisms because the application of soluble inorganic P or N fertilizers is not endorsed. Due to the limited supply of soluble nutrients in organic production systems, nutrient deficiency may limit plant growth and yield. The sole use of peat for pot-based cultures is also discouraged in organic production systems. Therefore, we have studied viable alternatives for highly soluble fertilizers and pure peat substrates using leek [Allium ampeloprasum L. var. Porrum] as a test plant. Plants were grown on peat-based substrates with different rates of compost additions, and with and without inoculation with arbuscular mycorrhizal (AM) fungi. Inoculation with a...

Effect of replacing organic grass-clover silage from primary growth with regrowth on feed intake and milk yield of dairy cows
Provedor de dados: 21
Autores: Naadland, Sondre Stokke; Steinshamn, Håvard; Randby, Åshild T.
Under Norwegian conditions, diets based on primary growth (PG) silage typically increase milk yield compared to silage prepared from the regrowth (RG). Organic PG, dominated by immature grasses, is often high in energy and low in crude protein (CP), whereas the opposite is the case for organic RG harvests, dominated by clover. Here, we tested the hypotheses that increasing proportions of RG will reduce the total supply of metabolizable energy, but increase the CP intake, and that there is a dietary optimal mix of PG and RG to meet requirements for optimal milk production. Sixteen Norwegian Red cows were used in an experiment designed with four balanced 4 × 4 Latin squares with 21-day periods to evaluate the effect of incremental replacement of PG with RG...

No-tillage (NT) and reduced tillage (RT) systems are well-known management tools for reducing soil erosion and improving soil fertility. NT and RT may improve the environmental and economic performance of organic farming, but they are still not common practice among organic farmers. This paper presents the effects of tillage [RT versus conventional tillage (CT)], fertilization (slurry versus manure compost) and biodynamic preparations (with versus without) on soil fertility indicators such as soil organic carbon (Corg), microbial biomass and microbial activity, soil nutrients and nutrient budgets in an organic farming system during the first six-year crop rotation period of a long-term experiment on a clayey soil in a temperate climate.

The implications of phasing out conventional nutrient supply in organic agriculture: Denmark as a case
Provedor de dados: 21
Autores: Oelofse, Myles; Jensen, Lars Stoumann; Magid, Jakob.
Soil fertility management in organic sys- tems, regulated by the organic standards, should seek to build healthy, fertile soils and reduce reliance on external inputs. The use of nutrients from conventional sources, such as animal manures from conventional farms, is currently permitted, with restrictions, in the organic regulations. However, the reliance of organic agriculture on the conventional system is considered problematic. In light of this, the organic sector in Denmark has recently decided to gradually phase out, and ultimately ban, the use of conventional ma- nures and straws in organic agriculture in Denmark. Core focal areas for phasing out conventional nutrients are as follows: (1) amendments to crop selection and rotations, (2) alternative...

Provedor de dados: 21
Autores: Lindqvist, H.; Nadeau, E.; Jensen, S.K.
Effects of wilting, ensiling and type of additive on atocopherol and b-carotene contents in legume–grass mixtures were examined. Swards of birdsfoot trefoil + timothy (Bft + Ti), red clover + timothy (Rc + Ti) and red clover + meadow fescue (Rc + Mf) were harvested as a first regrowth in August 2005. Forage was wilted to a dry-matter (DM) content of 273 g kg)1 and ensiled without additive or with an inoculant or acid. Wilting decreased a-tocopherol concentration by 30% in the Bft + Ti mixture (P = 0x015).  Untreated Bft + Ti silage had higher a-tocopherol content than red clover silages (56x9 vs. 34x2 mg kg)1 DM; P = 0x015). The a-tocopherol concentration of Bft + Ti silages increased during ensiling from 41x1 mg kg)1 DM in wilted herbage to 56x9, 65x2 and...

Effect of tomato variety, cultivation, climate  and processing on Sola l 4, an allergen from  Solanum lycopersicum
Provedor de dados: 21
Autores: Kurze, E.; Lo Scalzo, R; Campanelli, G.; Schwab, Wilfried.
Tomatoes (Solanum lycopersicum) are one of the most consumed vegetables worldwide.  However, tomato allergies in patients suffering from birch pollen allergy occur frequently.  Due to highly similar protein structures of the tomato allergen Sola l 4 and the major birch  pollen allergen Bet v 1, patients cross-react with allergenic proteins from tomato as well as  other fruits or vegetables. The aim of this study was to quantify Sola l 4 in various tomatoes  differing in color, size and shape for identification of varieties with a reduced allergen level.  Therefore, an indirect competitive ELISA using a specific polyclonal Sola l 4 antibody was  developed. In addition, two varieties, both cultivated either conventionally or organically and  furthermore...

Autores: Autio, Elena; Sihto, Ulla; Mononen, Jaakko; Heiskanen, Minna-Liisa.
The demand for information relating to the nutrition of horses in a cold environment is increasing with the popularity of loose housing of horses. This study examined the energy intake and growth of 10 weanling horses from November to March (22 weeks) in a loose housing system (paddock and insulated sleeping hall with deep-litter bed). The horses were measured weekly for body condition and body weight, and the feeding was adjusted according to a horse’s body condition. Metabolizable energy (ME) intake was compared to Finnish (MTT 2006) and Swedish (SLU 2004) nutrient requirements for 6–12-month-old horses. ME intake (75.5 ± 11.8 MJ d-1, mean ± SD) was on average 24.6% above the requirements. The intake varied in a non-linear fashion in the course of the...

Agroecology - as a scientific discipline and as an approach to sustainable farming practice - has objectives similar to those of organic agriculture. The paper sharpens the profile of both concepts and identifies strengths and weaknesses. The overarching challenge of both is to minimize trade-offs between food and fiber production on the one hand and non-commodity ecosystem services on the other hand. A comparison of the two approaches may well be inspiring, especially for the future development of organic food systems.  Best use of human, social and natural capital characterizes organic farmers, especially in developing countries, as documented by many case studies from sub Saharan Africa. That also applies to organic farms in temperate zones, although...

Tradition, Dynamics and Sustainability of Plant Species Composition and Management in Homegardens on Organic and Non-Organic Small Scale Farms in Alpine Eastern Tyrol, Austria
Provedor de dados: 21
Autores: Vogl, C. R.; Vogl-Lukasser, B.
In Eastern Tyrol (Austria), homegardens are an integral part of the farming system. The aim of this paper is to present evidence for the development of gardening in the study area and to identify differences/similarities between gardens at organic and non-organic farms. In 1997 and 1998, in homegardens on 91 organic and 105 non-organic farms from 12 communities, occurrence and abundance of cultivated plant species were surveyed and interviews were carried out about garden history, management and plant use. For the factor organic/non-organic, differences between gardens were statistically tested. Garden management is similar in organic/non-organic gardens, except mixed cropping and the use of alternative remedies to combat diseases, both with significantly...

Innate and learned olfactory attraction to flowering plants by the parasitoid Cotesia rubecula (Marshall, 1885) (Hymenoptera: Braconidae): Potential impacts on conservation biological control
Provedor de dados: 21
Autores: Fataar, Shakira; Kahmen, Ansgar; Luka, Henryk.
In conservation biological control, flowers can be used to increase the biological control potential of parasitoids, which benefit from the offered food sources. Besides exhibiting exploitable nectar, flowers should preferably be olfactorily attractive, as highly attractive flowers are easily located, reducing the time spent searching for food and subsequently increasing the per capita host searching efficiency. In this study we thus focused on the olfactory attractiveness of Fagopyrum esculentum Moench (Polygonaceae), Centaurea cyanus L. (Asteraceae) and Vicia sativa L. (Fabaceae) to Cotesia rubecula (Marshall, 1885) (Hymenoptera: Braconidae), a larval parasitoid of the cabbage pest Pieris rapae (Linnaeus, 1758) (Lepidoptera: Pieridae). With a Y-tube...

Klimaschutz wird die Themen Bodenschutz, Naturschutz, Wasserschutz und Tierschutz zukünftig als weitere zentrale Umweltwirkung ergänzen, um Landwirtschaft umweltfreundlich weiter zu entwickeln und zu vergleichen. Der Biobetrieb weist bei den beiden Treibhausgasen CO2 und N2O große Vorteile auf. Bei CH4 fehlt eine hinreichende Analyse, die Systemunterschiede dürften aber gering und eventuell auch nachteilig für den Biobetrieb sein.  Für den Einzelbetrieb sollte die absehbare Wirkung des Klimawandels vor Ort frühzeitig bei allen zukünftigen Entscheidungen für die Betriebsentwicklung, Investitionen und Bewirtschaftung berücksichtigt werden.

Peach orchard protection strategies and aphid communities: Towards an integrated agroecosystem approach
Provedor de dados: 21
Autores: Penvern, Servane; Bellon, Stéphane; Fauriel, Joël; Sauphanor, Benoit.
Aphid populations, including a widespread pest, Myzus persicae, are known to be affected by cultural practices, plant growth and natural regulation, but their control in orchards most frequently relies on regular treatments aiming to avoid direct damage and virus transmission. This study aimed first at characterising farmers’ management strategies towards aphids and, secondly evaluating them in terms of efficiency and impact on aphid natural enemies from 19 organic and conventional fruit farms in south-eastern France. Comprehensive variables made it possible to differentiate four strategies: intensive, optimised, input-substitution and integrated. The more integrated the strategy, the more diverse and abundant the aphids. The two most effective strategies...

Olfactometer screening of repellent essential oils against the pollen beetle (Meligethes spp.).
Provedor de dados: 21
Autores: Daniel, Claudia.
Essential oils can have an impact on pollen beetle (Meligethes spp.) host plant location behaviour. Lavender oil (Lavendula angustifolia) showed the highest repellency value in a previous laboratory study that compared five different essential oils (Mauchline et al., 2005). However, lavender oil is one of the most expensive essential oils – a fact that could seriously hamper on-farm implementation of this strategy. To find a cheaper essential oil with comparable efficacy to lavender oil, we compared the essential oils of Mentha arvensis, Eucalyptus globulus, Melaleuca alternifolia, Citrus sinensis, Citrus paradisi, Citrus limon, Juniperus mexicana, Abies sibirica, Illicium verum, Gaultheria procumbens, Cymbopogon flexuosus, Syzygium aromaticum, and Litsea...

Does organic agriculture reduce soil erodibility? The results of a long-term field study on loess in Switzerland
Provedor de dados: 21
Autores: Siegrist, S.; Schaub, D.; Pfiffner, L.; Mäder, P.
In a long-term field trial in northwestern Switzerland, the effects of organic and conventional land-use management on earthworm populations and on soil erodibility were investigated. A silt loam soil which had developed in deep deposits of alluvial loess characterised the study site. Three methods were applied to analyse soil erodibility, at three different periods between autumn 1992 and 1993: aggregate stability (measured in the laboratory by a high energy rainfall simulation and by percolation) and soil particle detachment (measured in the field by splash erosion). Earthworm biomass and density, as well as the population diversity, were significantly greater on the organic plots than on the conventional plots. Likewise, the aggregate stability of the...

In the present study, biogas potentials of multispecies swards including grass, lucerne, caraway, ribwort plantain and chicory from two- and four-cut regimes (Mix-2 and Mix-4) for mono-digestion applying batch and continuous modes under lab-scale conditions were investigated. The gas yields in terms of volatile solids (VS)loaded from Mix-2 and Mix-4 were compared with pure stand lucerne from the four cuts regime (Lu-4). The batch test results indicate that methane yield on a VS basis was highest from Mix-4 (295 L kg−1), followed by Mix-2 (281 L kg−1) and Lu-4 (255 L kg−1). The results were confirmed with continuous experiments, during which the reactor digesting Mix-4 was stable throughout the experiment with low ammonia and volatile fatty acid...

Autores: Marchi, C.; Andersen, L.W.; Panitz, F; Holm, L.-E.; Loeschcke, V.
454-sequencing of the genome was used to isolate and characterize nuclear 22 microsatellite sequences from the ground beetle Bembidion lampros (Carabidae). A 23 total of 4502 contigs containing di- to penta-nucleotide microsatellite repeats were 24 found (4211 perfect and 289 non-perfect repeats). Primers were developed and tested 25 for 34 microsatellite sequences. Of these 15 were tested on 1140 individual samples 26 amplifying on average 89% of samples and they did not deviate significantly from 27 Hardy-Weinberg and linkage equilibrium. These microsatellite sequences will be useful 28 in studying the effect of agricultural management techniques and various environmental 29 factors on a beneficial agricultural species.

Dioxins in organic eggs: a review
Provedor de dados: 21
Autores: Marion, de Vries; Rene, Kwakkel; Aize, Kijlstra.
Eggs contribute for about 4% to the daily dioxin intake of humans. Research among layer farms in the Netherlands and other EU countries has shown that organic eggs contain more dioxin than conventional ones and that a significant number of organic farms produce eggs with a dioxin content that exceeds the EU standard. The hens’ intake of dioxins from various sources leads to an increase in the dioxin content of organic eggs. These sources include plants, feed, soil, worms and insects, and compared with hens on conventional and free-range farms, organic hens make more use of these sources due to better access to the outdoor run. Plants appear to be relatively unimportant as a source of dioxins. Also commercial organic feed generally has very low dioxin...

Autores: Zaller, Johann G.; Saxler, N.
Earthworms are suggested to play an important role for the plant diversity of grassland ecosystems. Here we tested, whether (i) Lumbricus terrestris L. selectively feeds on seeds of grassland species, (ii) feeding patterns match with seed species present in surface casts in a permanent grassland and (iii) grassland plant seeds in different soil depths are relocated by the activity of earthworms. Food choice experiments with 10 plant species (3 grass spp., 4 non-leguminous herb spp., 3 leguminous spp.) showed that earthworms significantly selected between the offered seeds and generally favoured herbaceous species over grass species. Seed species in grassland surface casts did not correlate with seed species preferred by earthworms in the feeding...

Organic large scale dairy farming – a model study of the effect of stocking rate and distance from dairy facilities to farm land on productivity, nutrient balance and economic result
Provedor de dados: 21
Autores: Kristensen, T.; Tvedegaard, N.; Kristensen, I.S.
Organic livestock farms, at least in the northern part of Europe, are dominated by rather specialized units with production based on only one type of livestock, as dairy cows. The specialization is followed by a steady increase in size of the production unit, both in number of livestock and area belonging to the farm. In Denmark has the average organic dairy farm changed from 83 cows and 100 ha in 2000 to 136 cows and 172 ha in 2010; also production per cow has increased in this period from 6825 kg milk annually to 8100 kg in 2010. Such rather large changes over a decade often results in layout of the farm with long distance from the dairy facilities to the farm land. In organic dairy farming this is especially challenging as the dairy herd need to have...

Effect of Flock Size on Dioxin Levels in Eggs from Chickens Kept Outside
Provedor de dados: 21
Autores: Kijlstra, A.; Traag, W. A.; Hoogenboom, L. A. P.
To decrease dioxin uptake by the general population the European Union (EU) has set limits to the dioxin content of many foodstuffs including eggs. Eggs from free foraging chickens are known to have a higher dioxin content as compared to confined laying hens and it is the question whether these eggs can adhere to current EU regulations. The aim of the study was to investigate parameters that are involved in the contamination of eggs from chickens raised under “organic” conditions.  Samples from 34 organic farms including soil and earth worm samples were collected between September and December of the year 2003.  Dioxin levels were assayed by GC/MS. Various parameters were collected by on farm interviews. Egg dioxin content varied between 0.4 and 8.1 pg...

Provedor de dados: 21
Autores: Gambelli, Danilo; Solfanelli, Francesco; Zanoli, Raffaele.
Certification is an essential feature for organic products, and is based on controls/inspections to verify compliance with EU Reg. CE 834/07. Implementing a risk based inspection system can contribute to an effective and efficient organic control system, hence improving organic farming relative competitiveness.  This study is part of the CERCOST EU project, and analyses data from inspections on a sample of Italian organic farms, aiming at the identification of management and structural risk factors contributing to the occurrence of non-compliances. Risk analysis is based on the estimation of both parametric and non-parametric models using negative binomial panel estimators and Bayesian network modelling.

Feed Supplements for Young Dairy Breed Calves After Turn-Out to Pasture: Effect on Weight Gain and Subclinical Coccidiosis in Organic Production Systems
Provedor de dados: 21
Autores: Nielsen, B.K.; Thamsborg, S.M.; Kristensen, T.
On two organic farms, the effect of supplementation with either home-grown barley or organic commercial concentrates primarily based on local protein sources and barley, on weight gain and subclinical coccidiosis was investigated in 3-5 months old dairy breed calves in the period after turn-out to ryegrass/clover pastures. The calves (mean liveweight ± SD, 124 ± 24 kg and 133 ± 24 kg on Farm I and II respectively) were supplemented daily with 3 kg energy and protein-rich commercial concentrates (group EP), 3 kg barley (group E) or ½ kg barley (group Eres) for 8 weeks following turn-out on pasture.    Daily weight gains in the 8 weeks were for Farm I: 1216 and 1042 g/day for group EP and E (P &lt; 0.01) and for Farm II: 1071, 671 and 770 g/day for group EP,...

Gibt es Alternativen zu Kupfer?
Provedor de dados: 21
Autores: Schleuß, Uwe.
Zusammenfassend lässt sich nach den in Berlin (7. Fachgespräch zum Pflanzenschutz im ökologischen Landbau) vorgestellten Ergebnissen feststellen, dass momentan auf den Einsatz von Kupfer als Pflanzenschutzmittel im ökologischen Landbau noch nicht verzichtet werden kann. Um die Umweltauswirkungen auf Boden und Gewässer so gering wie möglich zu halten, muss die Aufwandmenge deutlich reduziert werden. Andererseits muss natürlich die fungizide Wirkung erhalten bleiben.  Ein Durchbruch beim Ersatz von Kupferpräparaten ist hinsichtlich Wirksamkeit und Kontinuität noch nicht gegeben. Deshalb ist zunehmend mehr Wert auf Präventionsmaßnahmen zu legen.

Sensory quality of scab-resistant apple cultivars
Provedor de dados: 21
Autores: Kühn, Senior Scientist Birka Falk; Thybo, Senior Scientist Anette.
Twenty-two scab-resistant apple cultivars were harvested in autumn 1999 and evaluated for sensory quality the following October, November and December. Multivariate analysis was effective in describing the comblex relationships and variabillity among the numerous attributes used to characterise apple quality. Crispness, mealiness, skin toughness, apple flavour, sweetness, unripe flavour and overripe flavour were informative attributes describing the variation in the sensory quality. Texture attributes, apple flavour and overripe flavour were affected by storage. Extended storage resulted in an increase in mealiness and overripe flavour and a decrease in crispness, juiciness and apple flavour. Many potential scab-resistant cultivars were suitable for...

'Suvetar' and 'Valotar' - new strawberry cultivars
Provedor de dados: 21
Autores: Hietaranta, Tarja; Parikka, Päivi.
The strawberry (Fragaria × ananassa) cultivars ‘Suvetar’ and ‘Valotar’ have been released from the breeding programme of MTT Agrifood Research Finland. Both new cultivars overwintered as well as the control cultivars ‘Jonsok’ and ‘Polka’. ‘Suvetar’ overwintered even better than ‘Polka’. ‘Suvetar’ was produced from the cross ‘Polka’ × ‘Emily’. It scored better than the control cultivars for sensory assessed skin resistance. Measured fruit firmness of ‘Suvetar’ was not significantly different from that of ‘Polka’, but was better than ‘Jonsok’. ‘Valotar’ originates from a cross between ‘Jewel’ and ‘Senga Sengana’. Its measured fruit firmness was better than that of ‘Jonsok’ and ‘Polka’. Considering sensory assessments, the good firmness seems to be largely...

Investigation on the influence of nematophagous fungi as feed additive on nematode infection risk of sheep and goats on pasture
Provedor de dados: 21
Autores: Epe, C.; Holst, C.; Koopmann, R.; Schnieder, T.; Larsen, M.; von Samson-Himmelstjerna, G.
Gastrointestinal nematodes in small ruminants cause high economic losses. Thus on most farms anthelmintic treatment is required. In response to increasing problems with anthelmintic resistance, biological control, for example the use of nematophagous fungi, has received significant attention. The aim of this study was to investigate the effect of Duddingtonia flagrans orally applied to small ruminants on natural infection with gastrointestinal nematodes in a field study in Northern Germany.  20 goats and 20 sheep were fed daily for 3 months with 5x105 spores of D. flagrans per kg bodyweight. Differences in body weight, faecal egg count and larval development in faeces and on pasture in comparison with same-sized control groups were analysed. After 3 months...

The implications of phasing out conventional nutrient supply in organic agriculture: Denmark as a case
Provedor de dados: 21
Autores: Oelofse, Myles; Jensen, Lars Stoumann; Magid, Jakob.
Soil fertility management in organic systems, regulated by the organic standards, should seek to build healthy, fertile soils and reduce reliance on external inputs. The  use of nutrients from conventional sources, such as animal manures from conventional farms, is currently permitted, with restrictions, in the organic regulations. However, the  reliance of organic agriculture on the conventional system is considered problematic. In light of this, the organic sector in Denmark has recently decided to phase out, and  ultimately ban, the use of conventional manures and straws in organic agriculture in Denmark by 2021. Core focal areas for phasing out conventional nutrients are 1) amendments to crop selection and rotations, 2) alternative nutrient sources...

Die Kontrolle gastrointestinaler Nematoden bei Weidetieren basiert seit fünf Jahrzehnten nahezu ausschließlich auf dem Einsatz von Anthelminthika. Die derzeit vor allem bei den Schaf- und Ziegennematoden weltweit zunehmende Resistenzproblematik erfordert die Entwicklung neuer, innovativer Kontrollstrategien, wobei die biologische Bekämpfung auf der Basis nematophager Pilze den derzeit erfolgversprechensten Ansatz darstellt. Erste Versuche zur Anwendung dieser Pilze bei Pflanzen und Tieren erfolgten bereits in den 30er Jahren, doch erst in den 90er Jahren führten Experimente zur Prüfung der Passagefähigkeit einzelner Spezies durch den Magen-Darm-Trakt von Rindern zur Isolation von Duddingtonia flagrans, womit ein maßgeblicher Fortschritt erzielt wurde....

Natural regulation of Delia radicum in organic cabbage production
Provedor de dados: 21
Autores: Meyling, N.; Navntoft, S.; Philipsen, H.; Thorup-Kristensen, K.
In a field experiment, we evaluated effects of three different organic white cabbage-cropping systems (O1, O2, O3) on the cabbage root fly, Delia radicum, and its egg predators and pupal parasitoids over 3 years. The three systems all complied with regulations for organic production, but varied in external nutrient input and N-recycling, and were compared to a conventionally farmed control. One organic system (O3) included an intercropped strip of green manure between crop rows. Oviposition by D. radicum was generally not reduced in organic cropping systems. However, higher pupae/egg ratios were observed in the conventional compared to all organic systems, indicating that immature survival from oviposition to pupation was reduced under all the three...

Purpose: This paper reviews the literature on the country-of-origin (COO) effect in the context of organic food and develops suggestions for further research in this area. Research has investigated COO effects and consumer responses to organic food, but there is little research on the combination of the two.  Design/methodology/approach: A narrative review of two research streams and their intersection, forming the basis for the development of a research agenda.   Findings: There are few studies analysing the possible interaction between the effects of organic and COO on consumers’ food preferences and choices. In general, COO seems to lose impact when other quality cues are salient. This suggests a lower impact of COO for organic than for conventional...

This work aims to evaluate the soil physical properties affected by cover crop rotation and soil management in a long-term experiment in southern Brazil. The experiment was established in 1986, with treatments combining six winter treatments and two tillage systems (conventional and no tillage). Bulk density, porosity, aggregate-size class distribution, and organic carbon content of the aggregates were determined at six depths. Bulk density was not affected by tillage systems and winter treatments. The soil disturbance by plowing enhanced the macroporosity, decreased the microporosity, and promoted the formation of smaller aggregate size, in comparison to no tillage. Apart from the soil management, all winter species increased the greater aggregate–size...

China is at the onset of an organic agriculture revolution. From 2000 to 2006, China has moved from 45th to 2nd position in the world in number of hectares under organic management. China now has more land under organic horticulture than any other country. In the year 2005/2006, China added 12% to the world’s organic area. This accounted for 63% of the world’s annual increase in organic land, and China now has 11% of the world’s organically managed land. The antecedents to China’s Organic Revolution are examined, and reveal further growth potential in the Chinese organic sector. Longitudinal analysis of China’s food production statistics reveals explosive growth, and the consequent capacity for export has implications for food exporting nations. China has...

Autores: Lammerts van Bueren, E.T.; Wilbois, K-P.; Østergård, H.
For further optimisation of organic agricultural systems, more focus is required on  organically produced seeds and the development of better adapted varieties.  Organic plant breeding and seed production need to comply with the concept of  naturalness as applied in organic agriculture, which not only includes the nonchemical  and agro-ecological approaches, but also the integrity of life approach.  As organic environments are less controllable and are more variable, breeding  should aim at improved yield stability and product quality by being adapted to  organic soil fertility as well as sustainable weed, pest and disease management.  Also the ability to produce economicacceptable seed yield avoiding seed-borne  diseases should be included. On the short...

Har søers rodeintensitet indflydelse på udvaskning - eller nytter tryneringning overhovedet
Provedor de dados: 21
Autores: Studnitz, Merete; Eriksen, Jørgen; Strudsholm, Karin.
Det er en almindelig antagelse, at tryneringning af udegående søer mindsker udvaskning af nitrat og andre næringsstoffer fra græsmarkerne, og at miljøet dermed skånes. Man kan se, at ringning forhindrer søerne i at rode, hvorved græsdækket holdes intakt på en stor del af marken det meste af året. Men fak-tisk ved vi ikke, om udvaskningen fra en mark med ringede søer er mindre end fra en mark, hvor søer kan rode. Det er vist, at der er væsentlig udvaskning fra områder omkring fodersted, sølehuller og hyt-ter fra marker, hvor søerne har været tryneringet. Det kan tænkes at denne punktforurening er værre for vandmiljøet end en jævn spredning af samme forurening.    Fra forsøg med ringede og ikke ringede søer ved vi, at søerne ikke lider ved at have trynering....

Background and Aims A number of root and root hair traits have been proposed as important for acquisition of P. However, it remains unknown whether these traits are most important in determining macro- and micronutrient uptake at low soil fertility. This study investigated the variations in root and root hair traits among spring wheat genotypes and examined which root and root hair traits are most important for high uptake of macro- and micronutrients.   Methods Six spring wheat genotypes were grown in a soil with low nutrient availability. The root and root hair traits as well as the content of macro- and micronutrients were identified.   Results A significant genetic variability in root and root hair traits was found. High root growth vigour and long and...

For the operationalization of the structured, stepwise selection procedure for non-target testing organisms integrated into the new EFSA guidelines for environmental risk assessment of GM plants practicaltools – i.e. ranking matrices – were developed. These tools – some of them are new and some are refinedfrom older ones – were tested using the GM case crop of TC 1507 maize. The selection procedure consists of six steps. The strategy builds on identifying the important ecological functions for the particularcropping system and compiling a species lists according to their ecological functions and presence inthe specific receiving environments. Subsequently, the species numbers are reduced in a systematic,stepwise fashion to a relevant and practical number...

Fundamental understanding of cellulose dissolution can improve the efficiency of biomass processing
Provedor de dados: 21
Autores: Ghasemi, Mohammad; Tsianou, Marina; Alexandridis, Paschalis.
A major barrier to the efficient utilization of biomass is the recalcitrance to dissolution of crystalline cellulose. The aim of this review is to provide an overview of the current understanding of the mechanism and kinetics of cellulose dissolution, with particular attention on how these findings can improve the efficiency of biomass processing. An improved fundamental understanding of cellulose dissolution can guide the rational selection of solvents and the optimization of processing conditions, thus leading to an enhanced utilization of biomass.

Nitrogen losses from grass ley after slurry application - surface broadcasting vs. injection
Provedor de dados: 21
Autores: Uusi-Kämppä, Jaana; Mattila, Pasi K.
As the livestock numbers on Finnish dairy farms have increased and most fields on dairy farms are under grass, it has become common to spread cattle slurry over grasslands. To estimate environmental effects of recurrent slurry applications, a 5-year field study was performed to compare nitrogen (N) losses to water and ammonia losses to air by volatilization, when cattle slurry was either surface broadcast or injected into clay soil after grass cuttings. Slurry was spread on the grass in summer (1996–1997) or both in summer and autumn (1998–2000). Biomass N uptake before grass harvesting and amount of soil mineral N in spring and autumn were measured and field N balances were calculated. Despite cool weather, up to one third of the ammonium N of broadcast...

Above- and belowground nitrogen distribution of a red clover-perennial ryegrass sward along a soil nutrient availability gradient established by organic and conventional cropping systems
Provedor de dados: 21
Autores: Hammelehle, Andreas; Oberson, Astrid; Lüscher, Andreas; Mäder, Paul; Mayer, Jochen.
Aims  Belowground legume nitrogen (N) composed of roots and rhizodeposition is an important N input to soils, but published data of belowground N vary broadly, probably due to extrapolation from short-term experiments and dissimilar growing conditions. We quantified belowground N inputs of red clover (Trifolium pratense L.) during two consecutive years in a clover-grass sward along a soil nutrient availability gradient.  Methods  We established a red clover-perennial ryegrass (Lolium perenne L.) model sward in microplots located in field plots of the DOK experiment, which has a 33-year history of organic and conventional cropping, resulting in a soil nutrient availability gradient. Four treatments were examined: the zero fertilisation control, bio-organic...

Gross sulphur mineralisation-immobilisation turnover in soil amended with plant residues
Provedor de dados: 21
Autores: Eriksen, J.
The rates of sulphur (S) released to and removed from the soil inorganic pool were estimated using the isotopic dilution technique. In an initial study fresh soil was mixed with combinations of two inorganic S levels (0 and 10 µg S g-1 soil) and three plant residues (wheat straw, perennial ryegrass and oilseed rape) and followed over 32 days of incubation. As 35S recovery was inadequate prior to day 2 and re-mineralisation of immobilised 35S occurred after day 8 thereby invalidating the method, estimates of gross S transformation rates should be based on data sampled between days 2 and 8. In the main experiment 16 plant residues with ranges in S contents of 0.08-0.81%, C/S ratios of 50-604 and lignin content of 0.9-10.8 were mixed with soil and...

Antifungal activity of phenolic compounds extracted from dried olive pomace
Provedor de dados: 21
Autores: Winkelhausen, Eleonora; Pospiech, Robert; Laufenberg, Günther.
The antifungal activity of phenolic compounds extracted from olive pomace against Alternaria solani, Botrytis cinerea and Fusarium culmorum was investigated. Olive pomace, a by-product of olive oil production, was used as a source of phenolic compounds. The extracted phenolics were added to a medium to reach phenol concentration of 0,1 and 0,2 %(w/v) and tested for their antifungal activity against the three fungi. In addition, the fungi were cultivated in a medium containing a commercial fungicide in the concentration of 0,2 % (w/v). Both of the phenolic concentrations inhibited the growth of all three fungi with the higher being more effective. It resulted in a four-fold reduction of the mycelial growth rate of A. solani and F. culmorum. The present...

Provedor de dados: 21
Autores: G., LAIGNEL; M., BENOIT.
Durant les cinq dernières années, l’Agriculture Biologique (AB) a connu, en  France, un développement inégalé : entre 1997 et 2002, la superficie conduite  en AB a été multipliée par trois et les effectifs de brebis par cinq. Cette  croissance s’accompagne d’un important besoin de références, en particulier  technico-économiques. L’observation sur trois années de 24 exploitations  ovines allaitantes en AB, comparées à 39 exploitations ovines allaitantes  conventionnelles, met en évidence une certaine spécificité des élevages AB,  tout en confirmant les principaux facteurs qui déterminent la marge par brebis  et le revenu. Etant donné le prix des aliments concentrés en AB, 1,8 fois  supérieur à celui des conventionnels, la quantité consommée est...

Effect of deep-rooted plant species on 15Nitrogen uptake and herbage yield in temporary agricultural grasslands
Provedor de dados: 21
Autores: Pirhofer-Walzl, K.; Eriksen, J.; Rasmussen, J.; Søegaard, K.; Høgh-Jensen, H.; Rasmussen, J.
Aims: Increase of plant diversity has been suggested to enhance grassland productivity and resource use efficiency. Most studies on agricultural grasslands have focused on functional diversity of mixtures comprising legumes and non-legumes, but there is little knowledge of plant nutrient acquisition from deep- and shallow-rooted grassland plant species. To investigate whether deep-rooted (chicory: Cichorium intybus L.; Lucerne: Medicago sativa L.) and shallow-rooted (perennial ryegrass: Lolium perenne L.; white clover: Trifolium repens L.) grassland plant species differ in herbage yield and depth dependent soil N-access, we investigated in the field if 1) a mixture comprising shallow- and deep-rooted grassland plant species has greater herbage yields than...

Comparison of interspecific competition and N use in pea–barley, faba bean–barley and lupin–barley intercrops grown at two temperate locations
Provedor de dados: 21
Autores: Knudsen, Marie Trydeman; Hauggaard-Nielsen, Henrik; Joernsgaard, Bjarne; Jensen, Erik Steen.
Mixed intercropping of spring barley (Hordeum vulgare L.) with field pea (Pisum sativum L.), faba bean (Vicia faba var. minor L.) or narrow-leafed lupin (Lupinus angustifolius L.) was compared to sole cropping in two field experiments at different locations, on a sandy loam soil and a sandy soil, in Denmark in 2001.   Grain legumes were dominant in intercrops on the sandy loam soil, except for lupin, whereas barley was dominant in intercrops on the sandy soil site. Combined intercrop grain yields were comparable to grain yields of the respective sole cropped grain legume or sole cropped, fertilized barley on each soil site. On the sandy loam soil, pea-barley and faba bean-barley intercrops increased the proportion of plant N derived from N2 fixation in...

Provedor de dados: 21
Autores: Weißmann, F.; Paulsen, H.-M.; Fischer, K.; Matthäus, B.; Bauer, M.; Pscheidl, M.; Vogt-Kaute, W.
Leindotter (Camelina sativa L.) ist eine viel versprechende Ölfrucht im ökologischen Pflanzenbau. Ihre Wertschöpfung ließe sich steigern, wenn der bei der Ölgewinnung anfallende Presskuchen als Futtermittel genutzt werden könnte. Allerdings verbietet das Futtermittelrecht den Einsatz von Leindotter und daraus hergestellten Produkten. Anträge auf Änderung sind jedoch erst dann Erfolg versprechend, wenn wissenschaftlich abgesicherte Empfehlungen zu einer unbedenklichen Einsatzhöhe gegeben werden können. Vor diesem Hintergrund wurden in einem Fütterungsversuch mit 192 männlichen Broilern (ISA 457) die Auswirkungen unterschiedlich hoher Anteile von Leindotterpresskuchen (LDPK) in einer ökologischen Ration auf die Mast- und Schlachtleistung untersucht.

Earthworm populations in low-input integrated crop management (ICM: no application of insecticides, fungicides and growth regulators) and organic farming systems were compared. The study was performed as a 3-year field survey using a paired-farm approach in six different locations in northwestern Switzerland. Earthworms were extracted from soils sampled from 24 winter cereal fields using a combined method of extraction by mustard flour solution and handsorting.  Earthworm communities differed between these farming systems. Over all sites, the mean biomass, abundance and species richness of earthworms found in the low-input ICM fields were significantly lower than in the organic fields. Adult earthworms in organic fields were 114% more abundant than in ICM...

Heterogeneity in Consumers' Perceptions and Demand for Local (Organic) Food Products
Provedor de dados: 21
Autores: Jensen, Jørgen Dejgård; Christensen, Tove; Denver, Sigrid; Ditlevsen, Kia; Lassen, Jesper; Teuber, Ramona.
“Local” is becoming increasingly important in consumers’ food purchase decisions. Perceived benefits of local foods are rather similar to those of organic products, including aspects of taste, food safety, animal welfare and reduced environmental impacts. Yet, only limited knowledge is available regarding different consumers’ conceptualization of local food. Our study addresses this research gap by investigating organic versus non-organic consumers’ perceptions of local foods and these perceptions’ association with purchasing behaviour. A mixed-methods approach was employed, combining eight focus group interviews (52 participants in total) with a representative survey of 1515 Danish consumers.  Focus group interviews revealed that Danish consumers mainly...

The “Organic Farming Massif Central” hub and fifteen partners lead a program on sustainability and on the technical and economic operation of OF livestock systems in the Massif Central. This systemic and multi-year study (2008-2011) is based on data from a constant sample over four years, from 56 farms comprising four types of products: cattle and sheep, dairy and meat. Over 4 years, the technical and economic results are quite stable, and at a good level, but with great variability inter-farms. With lower labor productivity, but with a more diversified crop rotation, a good food self-sufficiency and good technical skills, the farms with the highest income get an income more than four times higher than the farms with the lowest income .

Autores: PRACHE, S.; BALLET, J.; JAILLER, R.; METEAU, K.; PICARD, B.; RENERRE, M.; BAUCHART, D.
The ‘organic’ label on a product guarantees that synthetic fertilisers, pesticides and hormones are not used in the production process and that the use of pharmaceutical products and drugs is limited. However, product quality is often questioned and we have to anticipate the consumer demand for product quality guarantees. This study was conducted to compare the sensory and nutritional meat and carcass qualities of lambs raised under an organic (O) or a conventional (C) production system. Comparisons were made with both pasture-fed lambs and lambs that were stall-fed indoors with concentrate and hay. The experiment was conducted over two years for stall-fed lambs (S) (group O, n=24; group C, n=24) and three years for pasture-fed lambs (P) (group O, n=36;...

Økologiske grønsagsfrø - Økologisk produktion af grønsagsfrø i tunnel
Provedor de dados: 21
Autores: Boelt, B.; Deleuran, L.C.
Der er krav om at al udsæd til anvendelse i økologisk jordbrug skal være produceret økologisk. Inden for en række arter – specielt grønsager – er økologisk udsæd ikke tilgængelig, så indtil videre er der dispensation for ovennævnte krav.  I Forskningsprogram frøavl II er afprøvet økologisk frøproduktion af gulerod, blomkål og porre. Generelt er de opnåede resultater positive både, hvad angår udbytte og kvalitet. Specielt porre har vist sig som en særdeles robust kultur, medens der på Forskningscenter Flakkebjerg har været problemer med svampesygdomme i blomkålsproduktionen (knoldbægersvamp). I projektets sidste år er forskellige strategier mod knoldbægersvamp blevet afprøvet, men de endelige kvalitetsanalyser foreligger endnu ikke.

Autores: Silva, Claudia Bezerra da; Brito, Guilherme Rodrigues; Sanavria, Argemiro; Soares, João Paulo Guimarães.
As infestações parasitárias são responsáveis por sérios prejuízos econômicos na pecuária leiteira por causarem danos para a saúde animal. O controle de ectoparasitos com produtos químicos convencionais tem sido realizado de forma indiscriminada, ocasionando o desenvolvimento acelerado de resistência aos princípios ativos, contaminação do ambiente e dos produtos de origem animal, provocando preocupação na sociedade e órgãos governamentais. Desta forma, o uso de métodos alternativos, como o de plantas de potencial fitoterápico (ação repelente e larvicida) surge como um tratamento simples e de baixo custo, resultando no resgate da medicina popular, principalmente para atender o sistema orgânico de produção leiteira. Tais substâncias naturais são consideradas...

Reglering av åkermolke och andra fleråriga ogräs
Provedor de dados: 21
Autores: Vanhala, Petri; Lötjönen, Timo.
Fleråriga rotogräs har ökat i mängd både i konventionell och ekologisk odling i Finland. I synnerhet har åkermolke (Sonchus arvensis) och åkertistel (Cirsium arvense), som båda tål jordbearbetning, förökats. Eftersom de vanligtvis växer från rotutlöpare, har ögräsharvning bara liten effekt på rotogräs. Det behövs antingen kraftigare mekaniska åtgärder eller utnyttjande av grödans konkurrenskraft och andra odlingstekniska metoder.

Oospores of Phytophthora infestans in soil provide an important new source of primary inoculum in Finland
Provedor de dados: 21
Autores: Lehtinen, Ari; Hannukkala, Asko.
There have been numerous indications since the 1990s that oospore-derived primary infections play an increasing role in the epidemiology of potato late blight. The aim of this study was to verify that oosporederived epidemics actually occur in Finland. For this purpose, 20 suspected foci of oospore-derived potato late blight were scouted in 2000–2002. All of these were located in fi elds in which late blight had been observed in at least one of the four previous years. Primary symptoms in these foci occurred always on the lowest leaves near or touching the ground. Leafl ets typically showing numerous primary infections or lesions were in direct contact with the soil. In the former, oospores were observed after incubation. Soil samples from two experimental...

Zonas ripárias são áreas de saturação hídrica, permanente ou temporária, cuja principal função é a proteção dos recursos hídricos de uma microbacia. Essa pesquisa comparou a adequação do uso do solo de dois cenários de planejamento agrícola de uma microbacia: o cenário convencional, representando o método usualmente empregado, que apenas considera as classes de capacidade de uso da terra, e o cenário hidrológico, que inclui a delimitação e avaliação das zonas ripárias. Um estudo de caso foi realizado na Microbacia do Ribeirão São João (3.656 ha), no município de Mineiros do Tietê (São Paulo, Brasil). Mapas de Classe de Capacidade de Uso da Terra e de Adequação do Uso do Solo foram elaborados, utilizando o Sistema de Informação Geográfica (SIG), para a...

Explaining the global spatial distribution of organic crop producers
Provedor de dados: 21
Autores: Malek, Z; Tieskens, K.F.; Verburg, P.H.
Organic farming has been proposed as a feasible way to reduce the environmental impacts of agriculture, provide better products to consumers, and improve farmers' income. How organic farmers are distributed worldwide, however, remains unknown. Using publicly accessible registries of organic crop farmers we mapped their distribution globally and related it to local socio-economic, climatic, and soil characteristics. We show that organic crop farmers are mostly present in areas with favorable socio-economic and climatic conditions, both globally but also within countries. Within developed countries, the locations of organic crop farmers often do not differ significantly from the locations of conventional crop farmers. In developing countries, there are,...

Perspectives on nutrient management in mixed farming systems
Provedor de dados: 21
Autores: Watson, C.A.; Öborn, I.; Eriksen, J.E.; Edwards, A.C.
Changes in agricultural subsidies in Europe and the ready availability of fertilisers have allowed a spatial decoupling of livestock and crop production. This has increased the flow of nutrients that occurs between farms compared to within individual farms. In terms of nutrient cycling mixed farms provide the opportunity to re-integrate aspects of agricultural production. The degree of integration between crop and livestock production is defined by the reliance on the use of home-produced feed compared to imported feed, and is independent of intensity. Farm scale nutrient use efficiency (NUE) is inversely related to stocking density. Management of inputs and/or internal flows offers the scope to improve NUE on mixed farms. Greatest uncertainties in...

Les systèmes horticoles (arboriculture et maraîchage) sont parmi les plus intensifs en main d'oeuvre et en intrants ; la production conventionnelle repose sur un usage intense des produits phytosanitaires, pour satisfaire les critères d'accès aux circuits commerciaux des grandes et moyennes surfaces, et en particulier le « zéro défaut visuel ». Le secteur des fruits et légumes est extrêmement concurrentiel du fait de la faible part des aides (européennes, nationales) et souffre d'une forte distorsion des coûts de production entre états membres.

Optimising farmyard manure utilization by varying the application time and tillage strategy
Provedor de dados: 21
Autores: Hansen, Elly M.; Thomsen, Ingrid K.; Hansen, Martin N.
Abstract. Two field experiments were carried from 1999 to 2001 to assess the effectiveness of autumn, winter and spring application of straw-based farmyard manure (FYM). The soil was a sandy loam containing 106 g clay kg-1 situated in the temperate coastal climate of Denmark. The FYM was applied manually to experimental plots at a target rate of 300 kgN ha-1. The manure was incorporated by three initial tillage strategies (harrowing, rotavating or no-tillage) prior to ploughing. All combinations of tillage strategies were also carried out without manure application. Spring barley (Hordeum vulgare L.) was grown, followed by ryegrass (Lolium perenne L.). The results suggest that, as far as circumstances permit, FYM should be applied in spring to achieve the...

Sublethal effects of kaolin and the biopesticides Prestop-Mix and BotaniGard on metabolic rate, water loss and longevity in bumble bees (Bombus terrestris)
Provedor de dados: 21
Autores: Karise, Reet; Muljar, Riin; Smagghe, Guy; Kaart, Tanel; Kuusik, Aare; Dreyersdorff, Gerit; Williams, Ingrid; Mänd, Marika.
Kaolin is an inert material with a broad range of applications, e.g. as an insecticide and as a filling substance in the formulation of biopesticides. Hence, bees that dispense biopesticides to the field in the context of entomovectoring are exposed to elevated risks because of sideeffects of those products. Here, we investigated with use of bumble bee workers of Bombus terrestris L. the lethal and sublethal effects of (i) pure kaolin, (ii) the biofungicide Prestop-Mix containing the parasitic fungus Gliocladium catenulatum and kaolin and (iii) the bioinsecticide BotaniGard containing the entomopathogenic fungus Beauveria bassiana and compared with wheat flour powder that we considered safe for bumble bees. As the most important result, treatment with...

The challenges of including impacts on biodiversity in agricultural life cycle assessments
Provedor de dados: 21
Autores: Gabel, Vanessa M.; Meier, Matthias S.; Köpke, Ulrich; Stolze, Matthias.
Agriculture is considered to be one of the main drivers for worldwide biodiversity loss but the impacts of agricultural production on biodiversity have not been extensively considered in Life Cycle Assessments (LCAs). Recent realisation that biodiversity impact should be included in comprehensive LCAs has led to attempts to develop and implement methods for biodiversity impact assessment. In this review, twenty-two different biodiversity impact assessment methods have been analysed to identify their strengths and weaknesses in terms of their comprehensiveness in the evaluation of agricultural products. Different criteria, which had to meet the specific requirements of biodiversity research, life cycle assessment methodology, and the evaluation of...

Gene flow of oilseed rape (Brassica napus)according to isolation distance and buffer zone
Provedor de dados: 21
Autores: Damgaard, Christian; Kjellsson, Gösta.
The introduction of genetically modified (GM) crops in the EU has raised questions concerning gene dispersal and co-existence with non-GM farming. Quantitative estimates of the gene dispersal from fields with GM crops to fields with conspecific non-GM crops (conventional or organic) are therefore needed in order to suggest isolation distances and other management strategies to keep GM-pollination below acceptable threshold values. A meta-analysis of available gene-flow data for oilseed rape (Brassica napus) was performed. The probability distribution that seeds of non-GM oilseed rape are fertilised by foreign pollen grains from a neighbouring field of GM oilseed rape is modelled as functions of the width of the recipient (i.e. pollen receiving) field and...

Including grass leys in organic arable rotations has potentially several benefits such as suppression of certain weeds, increased biodiversity (i.e. pollinators), increased soil carbon sequestration and productivity among others. The biomass from the grass mixtures can be refined into protein feed concentrate for monogastrics that can partly replace imported soybean, while the fibre fraction can be used as ruminant feed or for biogas. The grass mixtures can also be used directly for biogas. Increasing diversity of the mixtures will potentially also increase the yield stability and the benefits for biodiversity (pollinators), while the number of cuts per year will also have an effect. Thus, the use of multispecies mixtures in organic arable rotation for...

Nutrient use efficiency and arbuscular mycorrhizal root colonisation of winter wheat cultivars in different farming systems of the DOK long-term trial
Provedor de dados: 21
Autores: Hildermann, Isabell; Messmer, Monika; Dubois, David; Boller, Thomas; Wiemken, Andres; Mäder, Paul.
BACKGROUND: For organic farming, cultivars are required with high nutrient use efficiency under nutrient limited conditions. Arbuscular mycorrhizal fungi (AMF) are known to contribute to nutrient uptake under low input conditions. We compared nutrient use efficiency (NUE) of old and modern organically and conventionally bred cultivars in organic and conventional systems and assessed AMF-root colonisation (AMF-RC) in relation to nutrient concentrations.    RESULTS: Cultivars and systems had a statistically significant effect on nitrogen (N) and phosphorus (P) concentrations and NUE parameters, whereas no genotype × environment interactions appeared. In contrast to N and P uptake, the NUE parameters were higher under organic than under conventional...

Diversity of mitochondrial large subunit rDNA haplotypes of Glomus intraradices in two agricultural field experiments and two semi-natural grasslands
Provedor de dados: 21
Autores: Börstler , Boris; Thiéry, Odile; Sýkorová, Zuzana; Berner, Alfred; Redecker, Dirk.
Glomus intraradices, an arbuscular mycorrhizal fungus (AMF), is frequently found in a surprisingly wide range of ecosystems all over the world. It is used as model organism for AMF and its genome is being sequenced. Despite the ecological importance of AMF, little has been known about their population structure, because no adequate molecular markers have been available. In the present study we analyse for the first time the intraspecific genetic structure of an AMF directly from colonized roots in the field. A recently developed PCR-RFLP approach for the mitochondrial rRNA large subunit gene (mtLSU) of these obligate symbionts was used and complemented by sequencing and primers specific for a particularly frequent mtLSU haplotype. We analysed root samples...

Antiparasitic activity of chicory (Cichorium intybus) and its natural bioactive compounds in livestock: a review
Provedor de dados: 21
Autores: Peña-Espinoza, Miguel; Valente, Angela H.; Thamsborg, Stig M.; Simonsen, Henrik T.; Boas, Ulrik; Enemark, Heidi L.; López-Muñoz, Rodrigo; Williams, Andrew R.
Increasing drug resistance in gastrointestinal (GI) parasites of livestock and concerns about chemical residues in animal products and the environment are driving the development of alternative control strategies that are less reliant on the use of synthetic drugs. An increasingly investigated approach is the use of bioactive forages with antiparasitic properties as part of the animal’s diet (nutraceuticals) or as potential sources of novel, natural parasiticides. Chicory (Cichorium intybus) is a multi-purpose crop and one of the most promising bioactive forages in temperate regions, and numerous in vivo trials have explored its potential against parasitic nematodes in livestock. However, it is unclear whether chicory can induce a direct and broad activity...

Biological control of plant pathogens on strawberries may be improved by the simultaneous application of different biological control agents (BCAs). Therefore, the compatibility of various BCAs which had previously shown to be effective against powdery mildew (Podosphaera aphanis (Wallr.) U. Braun &amp; S. Takam) under laboratory conditions was examined in vitro. Inhibitory effects between fungal and bacterial BCAs were demonstrated in dual culture tests on two solid nutrient media. Leaf disc assays with single and multiple strain treatments demonstrated either unaffected or significantly improved control of P. aphanis for many multiple strain treatments, even if antagonistic interactions previously occurred in dual culture tests. Highest inhibition of...

Soil fertility after 10 years of conservation tillage in organic farming
Provedor de dados: 21
Autores: Peigne, Joséphine; Vian, Jean François; Payet, Vincent; Saby, Nicolas.
It has become commonplace to consider ploughing as an agricultural practice that destroys soil fertility. Organic farmers have traditionally used the plough to till their soil and control weeds. However, there is a growing interest in adopting tillage practices without ploughing to preserve long-term soil fertility and in the hope, subsequently, of increasing crop yields. The aim of this paper is to assess if conservation tillage treatments in organic farming did in fact improve long-term soil fertility, wheat rooting and yield in a long term field experiment (2004–2015).   We compared the effects of conservation tillage treatments (superficial tillage – ST- with chisel at 15 cm depth and very superficial tillage – VST- at 5–7 cm depth) and conventional...

Vegetation in Danish field boundaries: A comparative study related to effects of agricultural practise
Provedor de dados: 21
Autores: Petersen, Sune.
Enrichment of biological diversity is often assumed to reflect good ecosystem integrity. Thus this  variable has for some time been a key factor of management strategies and environmental programmes.  The aim of the study presented here was primarily to observe, whether organic farming increases the  biological diversity of field boundary vegetation when compared to conventional farming. Secondly,  the aim was to consider, if increasing duration of the organic farming period also increases diversity.  Finally, ecological interpretations of the data were given by comparing different agricultural practises  in terms of general vegetation community patterns.  The results documented that diversity of plant species was significantly higher within the organic...

Henry Shoobridge, Tasmania's Pioneer of Organic Farming
Provedor de dados: 21
Autores: Paull, John.
Henry Shoobridge (1874-1963) was the pioneer of organic farming in Tasmania. He was the founder and the president of the island’s earliest organics advocacy group, the Living Soil Association of Tasmania (1946- 1960). The Shoobridge family had emigrated from Kent, England in 1822 bringing with them the hops cuttings with which they established hops as a successful primary industry in Tasmania. Henry Shoobridge was schooled at The Friend’s School, the Quaker school in Hobart. The Shoobridges pioneered the farming of hops in Tasmania, and Henry followed his forebears in this work. At the age of 71 years, Henry Shoobridge founded the Living Soil Association of Tasmania (LSAT) at a public meeting in Hobart on 30 August 1946. The LSAT affiliated with the...

Absence of both glutathione perioxidase activity and glutathione in bovine milk
Provedor de dados: 21
Autores: Stagsted, J.
Glutathione peroxidases are selenium-dependent, antioxidant enzymes that catalyse the removal of hydroperoxides using the tripeptide glutathione as reducing substrate. The presence and importance of glutathione peroxidase for the oxidative stability of bovine milk is unclear. We failed to detect any specific activity in bovine milk using careful and comprehensive assay conditions. The apparent activity in milk that has been ascribed previously to glutathione peroxidase was shown to be independent of added hydroperoxide, completely inhibited by &gt;6 mM EDTA, and could not be immunoprecipitated with a specific antiserum against the extracellular form of glutathione peroxidase. These results are incompatible with activity of glutathione peroxidase in bovine...

Hürden-Kombination bringt Sicherheit - Sichere und angepasste Herstellung von Öko-Fleisch- und -Wurstwaren ohne bzw. mit reduziertem Einsatz von Pökelstoffen
Provedor de dados: 21
Autores: Beck, Alexander; Dylla, Renate.
Bei der ökologischen Herstellung von Fleisch- und Wurstwaren werden vielfach auf die in der konventionellen Wurstherstellung verwendeten Konservierungsstoffe E 250 (Natriumnitrit) bzw. E 252 (Kaliumnitrat) verzichtet oder reduzierte Zugabemengen der Zusatzstoffe verwendet. Der Einsatz dieser Pökelstoffe in Öko-Fleisch- und Wurstwaren ist umstritten, da Nitrit toxikologisch nicht unbedenklich ist und es sich um eine chemisch-synthetisch hergestellte Verbindung handelt, die dem Grundsatz der Öko-Bewegung zur Minimierung des Einsatzes von Zusatzstoffen widerspricht.   Jahrelange Diskussionen um die (Nicht-)Notwendigkeit des Einsatzes von Pökelstoffen und die zögerliche Haltung des Gesetzgebers führten zu Rechtsunsicherheiten in der ökologischen Fleisch- und...

Organic versus GMO farming: Contamination, what contamination?
Provedor de dados: 21
Autores: Paull, John.
A landmark case against the planting of GMO crops in Australia has delivered a big win for GMO farmers and produced no protection for organic farmers. The case pitted farmer against farmer. An organic farmer, Steve Walsh, initiated the legal action against his GMO growing neighbour, Michael Baxter in the Supreme Court of Western Australia.  The Marsh and Baxter farms (477 hectares and 900 ha. respectively) are adjacent to each other and located in Kojonup, 260 km south east of the capital city of Perth in the wheat belt of Western Australia (WA) - and coincidentally nearby Broomhill was one of the earliest sites in the development of the organic movement in Australia (from 1930). Just before Baxter's first crop of Monsanto’s genetically modified (GM)...

Asian Spring for organic agriculture: Korea takes a lead
Provedor de dados: 21
Autores: Paull, John.
Korea’s Organic World Congress (OWC) was a milestone for Korea, for Asia, and for the world. It perhaps signals an Asian Spring for organics where Korea, in particular, and Asia, in general, are set to make rapid progress in meeting their aspirations and goals for reclaiming food and agriculture as organic. Korea’s OWC can serve to reinvigorate the momentum of organics in Asia where the organic statistics are dominated by the ‘organic giants’ of China and India. One remarkable enduring legacy of the OWC is the Namyangju Organic Museum. It is the world’s first museum dedicated to organic agriculture and was launched to coincide with the OWC. It is housed in a bold and strikingly modern new building. The museum presents a timeline of the history of organic...

Lite nitrogentap fra mjølkegarder som baserer seg på egen fôrprodukjson
Provedor de dados: 21
Autores: Steinshamn, Håvard; Bleken, Marina Azzaroli; Hansen, Sissel.
Tap av nitrogen (N) er et stort problem i landbruket, og i Europeiske direktiver blir det krevd forandring i landbrukspraksis for å redusere avrenningen. Ekstensiv mjølkeproduksjonen basert på heimeprodusert fôr er den mest effektive måten å bedre N-effektiviteten på. N-effektiviteten på gardsnivå reduseres dersom innkjøpet av fôr er høgt i forhold til planteproduksjonspotensialet på garden.

Bioraps: Erfolg auch in Finnland
Provedor de dados: 21
Autores: Hokkanen, H.; Menzler-Hokkanen, I.; Daniel, C.
In Finnland gibt es schon länger einen nennenswerten Anbau von Bioraps als bei uns. Nach einigen Startschwierigkeiten sind Finnlands Biobäuerinnen und Biobauern bei einer Anbaufläche von gegen 3000 Hektaren angelangt. Lernen können wir aus der finnischen Erfahrung vor allem zu den Themen Rapsglanzkäfer und Untersaaten.  Seit etwa 10 Jahren werden in Finnland jährlich 2000–3000 Hektaren Biosommerraps angebaut. Einheimisches kalt gepresstes Biorapsöl ist nicht nur in Bioläden, sondern auch in den meisten Supermärkten erhältlich. Auch in Finnland übersteigt die Nachfrage immer noch das Angebot; die Ölpressen nehmen zurzeit nur noch Bioproduzenten neu unter Vertrag.

Effects of strip intercropping concept with perennial  diversified grass-clover strip and annual winter rye-winter vetch intercrop as energy crops
Provedor de dados: 21
Autores: Hauggaard-Nielsen, Henrik; Johansen , Anders; Carter, Mette S.; Ambus, Per; Jensen, Erik Steen.
The combination of perennials and annuals in a strip cropping system is challenging primarily because the interspecific competitive ability of the perennials towards the annuals seems to be too dominating. Especially at the first harvest (tillering) closest to the adjacent grass-clover strip severe total dry matter production reductions was found ranging from 25%, 5% and 20% in the vetch SC, rye SC and vetch-rye IC, respectively. Rye in particular was suffering from the grass-clover interspecific competition with a SC yield of 700 g DM m-2 (0-25 cm) at maturity as compared to 1025 g DM m-2 when grown &gt; 150 cm away. When grown &gt;150 cm away from the grass-clover strip rye accumulate 8 g soil mineral N m-2,which is in the range of the expected according...

Quality of organic foods – a model for comparative analysis
Provedor de dados: 21
Autores: Vasileva, Elka; Ivanova, Daniela; Tipova, Nina; Stefanov, Stilian.
The quality and safety of organic products has been the subject of lively debate in the scientific community in recent years. The growing demand for organic food is based primarily on consumers’ concerns about the quality and safety and the perception that organic foods are healthier and safer than conventional foods. This paper identifies and makes analyses of comparative research studies on the quality of organic and conventional foods conducted over the last fifteen years. Based on the food quality science fundamentals a conceptual model for comparative testing of product quality is proposed. The model examines the dynamic relationship between its three basic components: "Designed Quality", "Perceived Quality" and "Achieved Quality". The proposed model...

The role of price as a product attribute in the organic food context: An exploration based on actual purchase data (D.6.7)
Provedor de dados: 21
Autores: Marian, Livia; Chrysochou , Polymeros; Krystallis Krontalis, Athanasios; Thøgersen, John.
High prices are often reported as an obstacle that inhibits the purchase of organic food products. The aim of this paper is to investigate how organic food products perform at different price levels and whether high prices are an advantage or a disadvantage for consumers’ repeat purchase of organic food. Based on analyses of actual purchase data, this study explores the effect of two product attributes (production method and price) on repeat purchase. The analysis is based on purchase data for four product categories (red meat, chicken, milk and hard cheese) registered by the GfK panel in 2011 in Denmark. The results show that within product categories, repeat purchase is linked more to production method than to price, and it is more prevalent for organic...

Analysis of non-compliances in the organic certification system in Turkey
Provedor de dados: 21
Autores: Zanoli, Raffaele; Gambelli, Danilo; Bruschi, Viola.
Organic farming in Turkey is experiencing a strong growth in recent years, with a particular attention to export towards Europe. International and domestic trade opportunities require an efficient control system for organic products. In this paper we analyse the data from inspections of two European control bodies in Turkish farms to analyse risk patterns of non-compliance with the organic regulation. A proportion test is performed to identify the types of crops that are more likely related to non-compliant operators.

Efterafgrøder har ringe effekt på P og K forsyningen på udpint lerjord
Provedor de dados: 21
Autores: Jensen, Lars Stoumann; Pedersen, Anders; Magid, Jakob; Nielsen, Niels Erik.
Efterafgrøder påvirker jordens tilgængelighed og tab af kvælstof (N). Dette er velkendt i økologiske sædskifter. Derimod ved vi mindre om, hvordan efterafgrøderne virker på tilgængeligheden af fosfor (P) og kalium (K) og på forsyning til den næste afgrøde i sædskiftet. Afhængig af jordens næringsstof status ved omlægning, vil økologisk produktion af salgsafgrøder med tiden kunne begrænses af næringsstofmangel, hvis der ikke tilføres P eller K. Denne mangel på næringsstoffer gælder ikke mindst i afgrødernes etableringsfase og for en række grøntsagskulturer med et lille rodsystem.    Når efterafgrøder kan bruges til at 'flytte rundt' på tilgængeligt N i sædskiftet, har man ofte i det økologiske jordbrug spekuleret over om det også kunne lade sig gøre for P...

In der ökologischen Schweinemast bestimmt das Vermarktungsziel die Auswahl der Genetik und Fütterungsintensität. Eine vornehmlich schlachtkörperqualitäts-orientierte Vermarktung, d. h. die Ausrichtung auf Fleischertrag, verlangt moderne Genotypen mit hoher körpereigener Proteinsynthesekapazität (also z. B. eher geringe Duroc-Genanteile im Masttier) und Rationen, die eine qualitativ hochwertige Aminosäurenversorgung gewährleisten, was zu einem mehr oder weniger hohen Nährstoffimport von außen in das landwirtschaftliche System hinein führt (high external input system). Fleischqualitäts-orientierte Vermarktungsziele tolerieren Genotypen mit niedrigerer körpereigener Proteinsynthesekapazität bzw. Rationen mit geringwertigerem Aminosäurenprofil bis hin zu...

Nature quality in organic farming: A conceptual analysis of considerations and criteria in a European context
Provedor de dados: 21
Autores: Tybirk, Knud; Alrøe, Hugo Fjelsted; Frederiksen, Pia.
Nature quality in relation to farming is a complex field. It involves different traditions and interests, different views of what nature is, and different ways of valuing nature. Furthermore there is a general lack of empirical data on many aspects of nature quality in the farmed landscape.    The present paper looks at nature quality from the perspective of organic farming, which has its own values and goals in relation to nature – the "Ecologist View of Nature". This is in contrast to the "Culturist View" characteristic of much conventional agriculture and the "Naturalist View" characteristic of the traditional biological approach to nature quality. This threefold distinction forms a framework for exploration of nature quality criteria in the farmed...

Population growth and climate change challenge our food and farming systems and provide arguments for an increased intensification of agriculture. A promising option is eco functional intensification through organic farming, an approach based on using and enhancing internal natural resources and processes to secure and improve agricultural productivity,  while minimizing negative environmental impacts. In this concept an active soil microbiota plays an important role for various soil based ecosystem services such as nutrient cycling, erosion control and pest and disease regulation. Several studies have reported a positive effect of organic farming on soil health and quality including microbial community traits.  However, so far no systematic quantification...

The use of medicinal plants and other natural multicomponent remedies might be one measure to reduce the use of antibiotics in livestock. Ethnoveterinary research has the potential to identify promising natural remedies. The knowledge about remedies for livestock was collected from farmers in six central Swiss cantons, Glarus, Obwalden, Nidwalden, Schwyz, Zug and Uri.  Between February and April 2013 49 interviews with 63 farmers (25 females and 38 males, aged 24–74) were conducted. We collected information on the manufacturing of 370 homemade remedies. Of these, 114 contained no plants, 26 contained a mixture of two to five plants, and 230 contained one plant species (defined as homemade single-herbal remedy report (HSHR)). These 230 HSHRs represented 68...

Effect of variety and environment on the amount of thiamine and riboflavin in cereals and grain legumes
Provedor de dados: 21
Autores: Witten, Stephanie; Aulrich, Karen.
Comprehensive information on B vitamin contents in cereals and grain legumes used for animal feeding is scarce. Thus, the objective of this study was to determine the contents of thiamine and riboflavin uniformly in a selection of cereals and grain legumes. Additionally, the evaluation of varietal and environmental effects on the amounts of both B vitamins was targeted. We analysed contents of thiamine and riboflavin with HPLC in 855 samples of different organically cultivated cereal and grain legume cultivars. Since the sample set was unbalanced, it had to be adapted for further statistical analyses. Data of 541 samples of ten cereal and grain legume cultivars was used to assess the influence of variety and environment with generalized linear models....

Consumption of animal-source food is criticised, among other reasons, for its relatively high environmental impact. It is, however, increasingly acknowledged that livestock can contribute to nutrition security if they upcycle low-opportunity-cost feed (LCF) – food waste, food processing by-products and grass resources – into nutritious animal-source food. So far, however, no study explored the allocation question “to which livestock should we feed what LCF to maximise livestock's contribution to human nutrition”. Here we optimise the use of the LCF available in the EU, using a model that assigns LCF to those livestock systems that maximise animal protein production. We included the five most common livestock systems in the EU – pigs, laying hens, broilers,...

Farmers are important actors for regional development and biodiversity protection. Agri-environment-climate measures (AECM) are therefore a central tool of the European Union to support its biodiversity conservation policy. AECM generally reward farmers for fulfilling predefined management actions or avoiding specific practices. In contrast, result oriented AECM are intended to reward farmers for the outcome of nature friendly management practices. This approach gives more flexibility in management and hence promotes farmers engagement and autonomy. Besides educational activities and agricultural advisory services farmers need user friendly tools to assess biodiversity in order to meet result oriented AECM. Thus, we present a biodiversity assessment scheme...

Autores: Zoppolo, Roberto J.; Stefanelli, Dario; Bird, George W.; Perry, Ronald L.; Weibel, Franco.
Orchard floor management impacts soil conditions and thus tree performance. This research was initiated to investigate the effects of alternative orchard floor management systems compatible with organic production on soil parameters using the“Pacific Gala” apple cultivar (Malus × domestica Borkh.) on three rootstocks of varying vigor. Alfalfa hay mulch, propane flame burner, and Swiss sandwich system(combination of resident vegetation and tilled strips)were compared from 2001 to 2005. These treatments were applied to tree rows which provided different vegetation-free areas. Contrasting additions of organic matter were evaluated for their effect on soil organic matter (SOM), C content, nitrate and ammonium availability, moisture, and soil food web through...

Provedor de dados: 21
Autores: Thorup-Kristensen, Kristian; Dresbøll, Dorte Bodin; Kristensen, Hanne L.
One core idea behind organic production is that cropping  systems should be less dependent on resource import than conventional production and minimize negative environmental effects. This study aimed to test novel organic rotations, designed to reduce reliance on external resource import. We compared a conventional system (C) and an organic system relying on manure import (O1) to two rotations (O2 and O3), both relying on autumn cover crops for soil fertility, and in O3 green manure rows were left as intercrops. Resource import differed between 149, 85, 25 and 25 kg N ha-1 year-1 in C, O1, O2 and O3.  Crop yields were lower in the organic systems (on average 82% of conventional yields), differing among crops, when based on the area grown with main crops....

Use of straight vegetable oil mixtures of rape and camelina as on farm fuels in agriculture
Provedor de dados: 21
Autores: Paulsen, H. M.; Wichmann, V.; Schuemann, U.; Richter, B.
Possibilities for using straight vegetable oil (SVO) from Camelina sativa (L.) Crantz (camelina or false flax) and its mixtures with Brassica napus (rape) SVO as fuel in adapted diesel engines are described with chemical parameters, measurements in a test engine and a field test in a tractor. Camelina as a crop is attracting attention in organic farming and is often used in mixed cropping systems with low competition to food production area. Camelina SVO has low oxidation stability. Its polymerization affinity limits the storage time and increase the risk of coking at hot motor components and of thickening processes in the lubricant oil of the engine. In mixtures with rape and camelina SVO, threshold limits for Conradson Carbon Residues and for oxidation...

Evolutionary changes of weed competitive traits in winter wheat composite cross populations in organic and conventional farming systems.
Provedor de dados: 21
Autores: Bertholdsson, Nils-Ove; Weedon, Odette; Brumlop, Sarah; Finckh, Maria R.
Seedling root and shoot growth in hydroponics and allelopathic activity using a bioassay have been studied in very diverse populations of winter wheat grown under either organic or conventional conditions for a number of generations and subjected only to natural selection. The study was conducted on seeds from generation 6 (F6) and 11 (F11) from three composite cross populations (CCPs) produced by the Organic Research Centre in the UK. Since the F5 the populations were maintained under organic and conventional conditions in Germany. Two parallel populations were created from each CC, resulting in a total of six organic and six conventional CCPs. The sets of parallel populations showed similar evolutionary trends indicating that the observed changes are...

The State and Consumer Confidence in Eco-Labeling: Organic Labeling in Denmark, Sweden, the United Kingdom and the United States
Provedor de dados: 21
Autores: Sønderskov, Kim Mannemar; Daugbjerg, Carsten.
Trustworthy eco-labels provide consumers with valuable information on environmentally friendly products and thus promote green consumerism. But what makes an eco-label trustworthy and what can government do to increase consumer confidence? The scant existing literature indicates that low governmental involvement increases confidence. This suggests that government should just provide the basic legal framework for eco-labeling and leave the rest to non-governmental organizations. However, the empirical underpinning of this conclusion is insufficient. This paper analyses consumer confidence in different organic food labeling regimes with varying degrees of governmental involvement. Using unique and detailed survey data from USA, United Kingdom, Denmark and...

The influence of phosphorus deficiency on growth and nitrogen fixation of white clover plants
Provedor de dados: 21
Autores: Høgh-Jensen, Dr Henning; Schjoerring, Dr Jan K.; Soussana, Dr Jean-Francois.
The effects of P deficiency on growth, N2-fixation and photosynthesis in white clover (Trifolium repens L.) were investigated using three contrasting relative addition rates of P, or following abrupt withdrawal of the P supply. Responses to a constant below-optimum P supply rate consisted of a decline in N2-fixation per unit root weight and a small reduction in the efficiency with which electrons were allocated to the reduction of N2 in the nodules. Abrupt P removal arrested nodule growth and caused a substantial decline in nitrogenase activity per unit root weight, but not per unit nodule mass.   Similarly, the rate of photosynthesis per unit leaf area was unaffected by abrupt P removal, while the CO2 acquisition for the plant as a whole decreased due to...

Organic Food "Made in China"
Provedor de dados: 21
Autores: Sternfeld, Eva.
China joined the international organic movement comparatively late. Challenged by the scarcity of arable land and a large population to feed, the Chinese Ministry of Agriculture (MoA) for many years has been reluctant to support organic farming that might result in a drop of agricultural output. On the contrary, China’s “Green Revolution” catapulted the country to a leading producer and user of agrochemicals in the world. This development came at a high cost for the country’s environmental quality and food safety.    In recent years, accumulating public complaints about environmental pollution, food poisoning, sickness and death of farmers poisoned by agrochemicals as well as increasing difficulties with agricultural exports rejected as a result of...

Autores: Padel, Susanne; Midmore, Peter.
The purpose of the paper is present experiences using a well established forecasting tool, the Delphi- method, to explore the dynamics of, and prospects for the development of the market for organic food in Europe. DELPHI, developed by the Rand co-operation to improve military technology forecasting, uses expert feedback to refine an informed perspective on complex or uncertain issues. This study used experts of the organic food market in 18 countries to explore factors influencing the development of the organic market; future market prospects, and the role of governments in future market development. The results show that short supply chains and focus on regional organic shops may be an indication of an earlier stage of market development, likely to be...

Autores: Nielsen, N.E.; Thomsen, I.K.; Berntsen, J.
Vårbyggens optagelse og udnyttelse af næringsstoffer, konkurrenceevne over for ukrudt samt sygdomsresistens har stor betydning for den økologiske planteavl. Opnåelse af en optimal ernæring forudsætter den rette kombination af et stort antal biologiske, fysiske og kemiske jord- og plantefaktorer.     Kulturplanter, som sås om foråret, starter i reglen med en moderat mangel på fosfor og kalium (Nielsen et al., 2003). I pløjelaget findes hovedparten af det plantetilgængelige fosfor og i en vis udstrækning tillige kalium og mikronæringsstoffer, mens det plantetilgængelige kvælstof og svovl ofte er fordelt i hele roddybden.

Investigating the selectivity of weed harrowing with new methods
Provedor de dados: 21
Autores: Rasmussen, Jesper; Bibby, Bo Martin; Schou, Anders P.
In six field experiments it was investigated whether row spacing, timing, direction and orientation of post-emergence weed harrowing in spring barley influenced the selectivity and whether it is important that increasing intensities of harrowing are generated either by increasing number of passes or increasing driving speed. Selectivity was defined as the relationship between crop burial in soil immediately after treatment and weed control. To estimate crop burial, digital image analysis was used in order to make the estimations objective. The study showed that narrow row spacing decreased selectivity in a late growth stage (21) whereas row spacing in the range of 5.3 cm to 24 cm had no effects in an early growth stage (12). Harrowing across rows decreased...

Biodiversity in Organic Horticulture – an Indicator for Sustainability and a Tool for Pest Management
Provedor de dados: 21
Autores: Wyss, Eric; Pfiffner, Lukas.
Conservation and enhancement of biodiversity are mentioned in the International Federation of Organic Agriculture Movements (IFOAM) standards and in all national guidelines as essential pillars for organic agriculture. Recent reviews show that organic agriculture enhances the number of species and the abundance of many taxa (plants, birds, mammals, earthworms, arthropods, soil microbes), compared with conventional agriculture. Considering the benefits for sustainability, a multi-criteria analysis shows that organic agriculture not only improves biodiversity but also has positive effects on soil (e.g., soil erosion, structure, biological activity), water (e.g., no pesticide residues) and climatic factors (e.g., air pollution). In organic horticulture,...

Autores: Leiber, Florian; Schenk, Isabel K.; Maeschli, Ariane; Ivemeyer, Silvia; Zeitz, Johanna O.; Moakes, Simon; Klocke, Peter; Staehli, Pamela; Notz, Christophe; Walkenhorst, Michael.
In response to increasing efforts for reducing concentrate inputs to organic dairy production in grassland-rich areas of Europe, a long-term study was conducted, which assessed the impacts of concentrate reductions on cows’ performance, health, fertility and average herd age. In total, 42 Swiss commercial organic dairy cattle farms were monitored over 6 years (‘Y0’, 2008/09 until ‘Y5’, 2013/14). In comparison with overall data of Swiss herdbooks (including conventional and organic farms), the herds involved in the project had lower milk yields, similar milk solids, shorter calving intervals and higher average lactation numbers. During the  first 3 project years farmers reduced the concentrate proportion (i.e. cereals, oilseeds and grain legumes) in the...

Outdoor production of slaughter pigs requires an optimized management to mitigate N pollution
Provedor de dados: 21
Autores: Eriksen, J.; Hermansen, J.E.
In Danish outdoor pig production the sows are usually kept on grassland, while their progeny are transferred at weaning to indoor housing with access to an outdoor concrete pen.    It may seem paradoxical that a large part of meat consumed from outdoor systems comes from pigs that during the majority of their life have been prevented from natural behaviour such as rooting, digging and grazing. The explanation is the drawbacks of rearing growers outdoors including huge space demand, high work expenditure, high feed consumption and high environmental costs due to nutrient losses to aquifers and the atmosphere caused by high nutrient load and difficulty maintaining grass cover. However, it may be questioned if pigs reared indoors comply with consumers’...

An indicator system of nature quality on organic fields
Provedor de dados: 21
Autores: Axelsen, J.; Bruus-Pedersen, M.; Larsen, T.; Krogh, P.H.
Soil fauna diversity, as well as total mite and springtail numbers was correlated with soil type, tillage intensity and fertiliser use as well as crop and grazing history and duration of the current state of the field. 430 samples taken in 2002 on a wide range of organically farmed fields also showed that soil type interacted with crop type and grazing intensity. A higher number of mites and springtails were found in crops that included clover, almost independently of soil type. Higher numbers of mites were found at high grazing intensity compared to low grazing intensity on the same soil type.   In 2003, microarthropods were collected in spring, summer and autumn in Southern Jutland, Mid-Jutland and Sealand. In each region both cereal and vegetable fields...

Symbiotic nitrogen fixation and N-transfer in a grass-white clover mixture
Provedor de dados: 21
Autores: Vinther, Finn P.
Symbiotic N2 fixation (SNF) and transfer of fixed N from clover to grass in a grass-white clover mixture was measured during two years using 15N isotope dilution techniques. White clover derived from 87 to 99% of its N from the atmosphere. The total SNF ranged from 150 to 277 kg N ha-1 yr-1, which corresponded to 34-45 mg N fixed per gram of white clover dry weight. The transfer of fixed N from clover to grass corresponded to approximately 10 kg N ha-1 yr-1.

Generalist predators in organically and conventionally managed grass-clover fields: implications for conservation biological control
Provedor de dados: 21
Autores: Birkhofer , K; Fließbach , A; Wise , DH; Scheu , S.
Organically managed agroecosystems rely in part on biological control to prevent pest outbreaks. Generalist predators (Araneae, Carabidae and Staphylinidae) are a major component of the natural enemy community in agroecosystems.  We assessed the seasonal dynamics of major generalist predator groups in conventionally and organically managed grass–clover fields that primarily differed by fertilisation strategy. We further established an experiment, manipulating the abundant wolf spider genus Pardosa, to identify the importance of these predators for herbivore suppression in the same system and growth period. Organic management significantly enhanced ground-active spider numbers early and late in the growing season, with potentially positive effects of plant...

Autores: Paull, John.
"Green Food" is a Chinese food production innovation, and has been described as "one of the most successful eco-labelling programs in the world" (Giovannucci, 2005, p.12). Green Food provides a "middle way" between chemical and organic farming. China's development of the Green Food concept resolves issues with both chemical and organic agriculture - for the former by offering reduced pesticide use, and for the latter by providing a stepped pathway for conversion from chemical to organic agriculture while simultaneously providing a Green Food price premium. After nearly two decades of development, Green Food is by now well known to Chinese consumers, and is readily available for retail purchase in China. China has 10 million hectares (150 million mu) of...

To obtain a reference status prior to cultivation of genetically modified oilseed rape (OSR, Brassica napus L.) in Switzerland, the occurrence of feral OSR was monitored along transportation routes and at processing sites. The focus was set on the detection of (transgenic) OSR along railway lines from the Swiss borders with Italy and France to the respective oilseed processing factories in Southern and Northern Switzerland (Ticino and region of Basel). A monitoring concept was developed to identify sites of largest risk of escape of genetically modified plants into the environment in Switzerland. Transport spillage of OSR seeds from railway goods cars particularly at risk hot spots such as switch yards and (un)loading points but also incidental and...

Since the mid 1980s, organic farming has become the focus of significant attention from policy-makers, consumers, environmentalists and farmers in Europe and state institutions have become increasingly involved in regulating and supporting the organic sector. Reflecting the multiple goals for organic farming and for agricultural policy, a varied and complex range of policy measures have been developed and implemented to support the organic sector. However, balancing societal and consumer/market goals and balancing institutional and private stakeholder interests in the organic sector present particular challenges for policy-making. The key issues of current organic farming policy addressed in this special issue therefore specifically consider the two...

Red (RC) or white (WC) clover were grown in mixture with grasses, ensiled and offered to dairy cows in early lactation over two successive years (48 cows per year) to compare grassland yield, feed intake, milk production and milk quality. The crops were ensiled in round bales and proportional mixtures of the second and third cut prepared each year were used to ensure that the silage treatments were representative of the crop. In addition to silage type, concentrate supplementation, without and with (10 kg/day), was included as a factor in a 2×2 factorial, continuous experiment. Total dry matter (DM) yield, silage chemical composition and totalDMintake was hardly affected by silage type. There was no effect of silage type on milk yield and milk constituents...

Autores: Wyss, Eric; Daniel, Claudia.
De nombreux ravageurs des légumes, comme p. ex. la mouche de la carotte, la mouche du chou ou la cécidomyie du chou, font vraiment du rase-mottes: ils se déplacent dans la végétation ou très bas au-dessus d’elle. Des filets verticaux, véritables clôtures anti-insectes, permettent de les stopper à leur entrée dans les cultures.

Autores: Böhm, Herwart; Verschwele, Arnd.
Perennierende Unkräuter wie die Ampfer-Arten oder die Acker-Kratzdistel stellen im Ökologischen Landbau immer noch ein großes Problem dar. Im Rahmen des Bundesprogramms Ökologischer Landbau wurde daher in einem Verbundvorhaben der FAL und der BBA verschiedene Fragestellungen zu dieser Thematik bearbeitet:   Eine bundesweite Umfrage von über 150 ökologisch wirtschaftenden Landwirten ergab , dass derzeit ca. 30 % der Ackerflächen mit der Acker-Kratzdistel (Cirsium arvense) verunkrautet sind Die meisten Landwirte (n=140) haben sowohl Probleme mit C. arvense als auch mit Rumex spp. und/oder Agropyron repens, 96 von ihnen klagten sogar über extreme Schwierigkeiten mit diesen ausdauernden Unkrautarten.  Sowohl in der Umfrage als auch in den Untersuchungen auf...

SOIL ENZYME ACTIVITIES RECOVERY AFTER ORGANIC TREATMENTS OF DEGRADED AREAS WITHIN VINEYARDS
Provedor de dados: 21
Autores: Lagomarsino, A.; Agnelli, A.E.; Fulchin, E.; Giffard, B.
Soil enzymes were used to assess the impact of different treatments applied in four farms, each one with three vineyards as replicates, on soil functionality. 8 enzymes related to C, N, S and P cycling were measured and functional diversity indexes were estimated. Three treatments were compared: compost, green manure and dry mulching with respect to degraded and non-degraded soil. The four vineyards showed different enzymatic patterns and response to treatments. Vineyards with the largest difference between degraded and non-degraded soil have benefited more largely from the treatments. In particular, dry mulching seemed to be more effective than green manure or compost, with the exception of San Disdagio. However, the effect the short term.

Autores: Salomé, Clémence; Coll, Patrice; Lardo, Egidio; Metay, Aurélie; Villenave, Cécile; Marsden, Claire; Blanchart, Eric; Hinsinger, Philippe; Le Cadre, Edith.
Land management aiming to sustain ecosystem services is an important issue, especially in biodiversity hot spots such as found in Mediterranean areas. In Mediterranean areas, viticulture is an important land use. Vineyards are frequently found on inherently poor soils and are submitted to intensive management practices, which threaten soil functioning and associated ecosystem services. To encourage winegrowers and stakeholders to be reflective and adapt their vineyard practices, we evaluated the effects of three soil management practices (inter row plant cover duration, weeding and fertilization strategies) on soil functioning in 146 commercial plots distributed in Southern France, by a complementary set of biological and physico-chemical indicators. We...

Systemic Sustainability of the French Organic Rice and PGI Einkorn Value Chains: A Preliminary Assessment Based on Network Analysis
Provedor de dados: 21
Autores: Quiédeville, Sylvain; Bassene, Jean-Baptiste; Lançon, Frédéric; Chabrol, Didier; Moustier, Paule.
Public authorities and consumers increasingly support food value chains that are more environmentally friendly. However, these value chains are faced with technical, economic and institutional limitations, calling into question their long-term viability. Based on two case studies of alternative food chains in France, namely einkorn (Triticum monococcum) in Haute Provence and organic rice in the Camargue, we evaluated their capacity to remain both viable and environmentally, economically and socially sustainable. After assessing the traditional economic, social and environmental performance of their sustainability, we performed a network analysis to determine the survivability of the systems. The combined use of the traditional pillars of sustainability and...

Autores: Crichton, Stuart O.J.; Kirchner, Sascha M.; Porley, Victoria; Retz, Stefanie; von Gersdorff, Gardis; Hensel, Oliver; Weygandt, Martin; Sturm, Barbara.
Consumer trust in the food industry is heavily reliant upon accurate labelling of meat products. As such, methods which can verify whether meat is correctly labelled are of great value to producers, retailers, and consumers. This paper illustrates two approaches to classify between, fresh and frozen thawed, and in a novel manner matured and matured frozen-thawed, as well as fresh and matured beef using the 500-1010 nm waveband, captured using hyperspectral imaging, and CIELAB measurements. The results show successful classification based upon CIELAB between 1) fresh and frozen-thawed (CCR = 0.93), and 2) fresh and matured (CCR = 0.92). With successful classification between matured and matured frozen-thawed beef using the entire spectral range (CCR =...

Molecular diagnostic methods can prevent unnecessary rejection of organic seed lots
Provedor de dados: 21
Autores: Justesen, A.F.; Pinnschmidt, H.O.; Hansen, H.J.
In some years, large amounts of organic seed lots are discarded due to the presence of high levels of seed-borne diseases. In barley it is especially the presence of the fungal species Pyrenophora teres (barley net blotch) and P. graminea (barley leaf stripe), which causes rejection of seed lots. A real-time PCR method for detection and quantification of P. graminea has been developed.

Organic farming is based on the idea of an environmentally-friendly food production system with high animal welfare standards. But in the real world there are many difficulties in reaching these goals. Many problems in animal health and welfare remain unresolved, presenting a challenge for individual producers and the industry as a whole. These inculde: achieving balanced, 100%-organic, feed rations that produce adequate growth rates and high quality products, animal-friendly transport and slaughtering, the sustainable use of local resources and, last but not least, profitability and the efficent use of resources.

Autores: Braunisch, Veronika; Home, Robert; Pellet, Jérôme; Arlettaz, Raphaël.
A wide gap between research and practice hinders the implementation of biodiversity conservation recommendations. As subjects studied by conservation scientists might bear little relevance for implementation, surveys have identified and framed research questions relevant to conservation in practice. No attempts to prioritize these questions have yet been published, although it would provide invaluable information for steering practice-oriented research. We surveyed Swiss conservation practitioners with the aim of identifying and prioritizing their needs in terms of useful scientific information. A first inductive survey of a selected subgroup generated a list of relevant research questions that were reformulated to be generalizable to all main Swiss...

Developing a welfare assessment system for use in commercial organic egg production
Provedor de dados: 21
Autores: Hegelund, L.; Sørensen, J.T.; Johansen, N.F.
A welfare assessment system is being developed for commercial organic egg production based on indicators of behaviour, health, system, and management, which is the general Danish Institute for Agricultural Science (DIAS) concept for assessing animal welfare at farm level. The welfare assessment system works as an advisory tool for farmers, helping them to improve welfare in their flocks. Identification of individual animals in organic egg production is impossible; therefore, management and welfare assessment are based on flock evaluation. Mortality is often a major welfare problem in organic egg production, to some extent caused by inefficient disease detection and control. Health indicators are therefore closely monitored, including variations in live...

Mixed grazing with heifers and pregnant sows
Provedor de dados: 21
Autores: Søegaard, Karen; Sehested, Jakob; Danielsen, Viggo.
In 1999, a mixed grazing system with heifers and pregnant sows was compared with grazing systems with heifers and sows alone. Normally, herbage quality used for sow grazing is not optimal for high herbage intake and it was therefore examined whether mixed grazing with heifers could improve the grazing system. Herbage quality and botanical composition of the sward was best in swards where heifers grazed alone, followed by swards with mixed grazing and the poorest quality and composition were in swards, where the sows grazed alone. The daily weight gain of the sows tended to be higher and the weight gain of the heifers was significantly higher for mixed than at mono grazing. The mixed grazing system seems to be a usable alternative for grazing sowas.

Keel bone damage (KBD) in laying hens is an important welfare problem in both conventional and organic egg production systems. We aimed to identify possible risk factors for KBD in organic hens by analysing cross-sectional data of 107 flocks assessed in eight European countries. Due to partly missing data, the final multiple regression model was based on data from 50 flocks. Keel bone damage included fractures and/or deviations, and was recorded, alongside with other animal based measures, by palpation and visual inspection of at least 50 randomly collected hens per flock between 52 and 73 weeks of age. Management and housing data were obtained by interviews, inspection and by feed analysis. Keel bone damage flock prevalences ranged from 3% to 88%....

Emmer wheat [(Triticum dicoccum Schrank (Schuebl)] is after bread, durum and spelt wheat further species of wheat  used for economic purposes. Organic farmers and producers have become more and more interested in marginal crops  such as the tetraploid emmer wheat because of its suitability for organic farming. In spite of its historical role, present distribution of emmer is very limited. The work analyzes the problem of growing possibilities of emmer and its suitability for cultivation in organic farming. In the Czech Republic it is grown only a few farms, but in Austria is more popular now. Possible candidates for the cultivation of emmer has several options about where to obtain a suitable variety. The best option appears to be the choice of legally...

Punch planting, flame weeding and delayed sowing to reduce intra-row weeds in row crops
Provedor de dados: 21
Autores: Rasmussen, Jesper; Henriksen, Christian Bugge; Griepentrog, Hans W.; Nielsen, Jon.
Punch planting has recently been suggested to reduce intra-row weeds in organically grown row crops. In this method holes are punched in the ground with a minimum of soil disturbance and seeds are inserted into them, without soil disturbance outside the hole. The first experiments with a tractor-mounted prototype of a dibber drill (MK III) are presented here. In two years, three plant establishment procedures were compared at five different sowing dates in sugar beet and direct-sown onion. The plant establishment procedures were 1) normal sowing and mechanical control of weeds in the stale seedbed (N), 2) N + pre-emergence flame weeding (N+F), and 3) punch planting and flame weeding to control weeds in the seedbed and prior to crop emergence (P +F).

Autores: Holinger, Mirjam; Früh, Barbara; Stoll, Peter; Graage, Robert; Wirth, Sandra; Bruckmaier, Rupert; Prunier, Armelle; Kreuzer, Michael; Hillmann, Edna.
Entire male pigs display more aggressive and sexual behaviour. This might cause a condition of chronic stress and impair their welfare. In order to assess chronic stress in entire and castrated male pigs, as well as effects of providing grass silage as occupational and feed material on behaviour and health, we carried out a 2 × 2 × 2-factorial experiment with 147 growing-finishing pigs. Factors investigated were castration (entire/castrated), chronic intermittent social stress exposure (yes/no) and access to grass silage (yes/no), as well as their interactions. The stress exposure treatment consisted of repeated short-term confrontations and separations. We recorded different behavioural variables, circadian rhythm of salivary cortisol, response to an ACTH...

In 2007 two long-term trials were established in Kenya to contribute research-based evidence to the global debate on the productivity, economic viability and sustainability of different agricultural production systems. These trials compare conventional (Conv) and organic (Org) farming systems at high and low input levels at two locations, i.e. Chuka, with Humic Nitisols, high inherent soil fertility and rainfall, and Thika, with Rhodic Nitisols with low soil fertility and rainfall. The high input systems (High) represent commercial-scale, export-oriented production that uses the recommended amounts of fertilisers, pesticides and irrigation water to generate high yields, whilst the low input systems (Low) represent local smallholder practices, using...

Autores: Nerad, Daniel; Škeřík, Josef; Kazda, Jan; Kuchtová, Perla; Baranyk, Petr.
Different responses of winter oilseed rape (WOSR) varieties to various growing locality conditions as well as to the intensity of technological inputs are known. Organic grower-need varieties provide sufficient yield even within extensive growing conditions. Ten commonly grown line varieties in the Czech Republic were tested using extensive organic growing technology. These varieties were evaluated for the occurrence of fungal diseases by ripening and seed yield. Some of OSR tested varieties proved to have higher resistance to fungal diseases as well as significantly higher seed yields. Higher resistance against Phoma lingam proved varieties Caracas, Ontario, Liprima, Cando and Manitoba. Higher resistance against Sclerotinia sclerotiorum proved varieties...

Farmers adoption of integrated crop protection and organic farming: Do moral and social concerns matter?
Provedor de dados: 21
Autores: Mzoughi , Naoufel.
We investigate empirically the role of moral and social concerns in farmers' decision to adopt integrated crop protection (IP) and organic farming (OF). A survey questionnaire has been sent to 1286 fruit-growers and vegetable producers located in the French areas of Alpes de Haute Provence, Hautes-Alpes and Vaucluse. Analysis of individual responses (N = 243) shows that, although economic concerns play a strong role, a significant number of respondents give high importance to moral and social ones. We also examine how these considerations matter according to different crop protection strategies, that is, conventional farming, IP and OF. Using a multinomial logistic regression, we find that (1) social concerns (e.g., showing to others one's environmental...

Autores: Pfiffner, Lukas; Luka, Henryk.
We compared the effects of different low-input farming systems on carabids and spiders.   The study was performed in a 3-year field survey using a paired-farm approach in six different landscapes units in northwestern Switzerland considering also the nearby semi-natural habitats. Carabids and spiders were sampled in 24 winter cereal crops and 18 semi-natural habitats using five funnel pitfall traps per site.    Considering all cereal sites, in low-input ICM fields (= no insecticides, fungicides and growth regulators; ICM: Integrated crop management) 36% less carabids and 8% less spider specimens were found. In several cases, carabid populations of organic fields were significantly richer in species and abundance than in the low-input integrated crop...

Dispersal of Rhagoletis cerasi in commercial cherry orchards: Efficacy of soil covering nets for cherry fruit fly control
Provedor de dados: 21
Autores: Daniel, Claudia; Baker, Brian.
Demand for organic cherries offers producers a premium price to improve their commercial viability. Organic standards require that producers find alternatives to pesticides. Soil treatments to control the European cherry fruit fly Rhagoletis cerasi (L.)(Diptera: Tephrididae) appear to be an attractive option. However, soil treatments can only be effective if the migration of flies is low, because mature flies may migrate from near-by trees for oviposition. To examine the general potential of soil treatments and to understand the dispersal and flight behaviour of R. cerasi within orchards, experiments using netting to cover the soil were conducted in two orchards with different pest pressure during two years. The netting reduced flight activity by 77% and...

An approach to include soil carbon changes in life cycle assessments
Provedor de dados: 21
Autores: Petersen, B.M.; Knudsen, Marie Trydeman; Hermansen, J.E.; Halberg, Niels.
Globally, soil carbon sequestration is expected to hold a major potential to mitigate agricultural greenhouse gas emissions. However, the majority of life cycle assessments (LCA) of agricultural products have not included possible changes in soil carbon sequestration. In the present study, a method to estimate carbon sequestration to be included in LCA is suggested and applied to two examples where the inclusion of carbon sequestration is especially relevant: 1) Bioenergy: removal of straw from a Danish soil for energy purposes and 2) Organic versus conventional farming: comparative study of soybean production in China. The suggested approach considers the time of the soil CO2 emissions for the LCA by including the Bern Carbon Cycle Model. Time...

The rapid development of the economy has created an increasing demand for energy in China. The limited resources of fossil energy are a risk for the development of China. Sustainable agriculture like organic farming (Green AAA in China) with biomass energy - as done in developed countries like Germany - is an option to reduce these risks. In China, agriculture is not energy efficient, and the intensive farming is not sustainable. The scientific challenge is to develop sustainable farming systems which can fulfill national food security, food safety and considerable renewable energy production without harming the environment, and are acceptable to the people and the economy. The protection and intelligent utilization of resources is the core of rural...

Autores: Höjer, Annika; Adler, Steffen; Purup, Stig; Hansen-Møller, Jens; Martinsson, Kjell; Steinshamn, Håvard; Gustavsson, Anne-Maj.
Phytoestrogens are hormone-like substances in plants that can substantially influence human health (positively or negatively), and when fed to dairy cows are partly transferred to their milk. The aim of this study was to investigate effects of varying the botanical composition and regrowth interval of legume-grass silage on phytoestrogen intake and milk phytoestrogen concentrations. In one experiment, 15 Swedish Red dairy cows were fed two- or three-cut red clover-grass silage, or two-cut birdsfoot trefoil-grass silage. In a second experiment, 16 Norwegian Red dairy cows were fed short-term ley silage with red clover or long-term ley silage with white clover, and the effects of supplementation with α-tocopherol were also tested. There were high...

Autores: Thomsen, I. K.; Schjønning, P.; Christensen, B. T.
In order to investigate the effect of soil moisture and texture on C and N mineralization of applied organic matter, sheep faeces was sandwiched between two halves of intact soil cores and incubated at 20°C. The soils contained 10.8 (L1), 22.4 (L3) and 33.7% (L5) clay, respectively, and were drained to seven different matric potentials in the range –15 to –1500 hPa. Evolution of CO2-C was determined during four weeks of incubation. Contents of NO3-N, 15N and microbial biomass N were determined at the end of the incubation.  The net release of CO2-C from the faeces (estimated as the difference between soils with and without faeces) and the total CO2-C evolution from soils with faeces was not related to soil moisture contents. Most CO2-C evolved from faeces...

Development of reduced tillage systems in organic farming in Europe
Provedor de dados: 21
Autores: Mäder, Paul; Berner, Alfred.
No-tillage and reduced tillage are considered sustainable options of conservation tillage. While US organic farming researchers have focused on no-tillage, European organic farming researchers have concentrated on reduced tillage through the reduction of tillage depth or the application of noninversion tillage practices. Combinations of these two approaches have been implemented by the use of the two-layer plow or the layer cultivator. These innovations often came from farmers, aiming at reducing off-farm inputs such as fuel, and saving costs and labor, while at the same time building up soil fertility. Systematic, documented research on reduced tillage systems in Europe started only 1–2 decades ago, with experiments in Germany, Switzerland and France....

Background    The organic food sales have been increasing during the recent years. It has been hypothesised that organically grown fruits are healthier based on their higher content of phytochemicals. However, data on the bioavailability of phytochemicals from organically or conventionally produced plant foods are scarce.   Methods    Two human intervention studies were performed to compare the bioavailability of polyphenols in healthy men after ingestion of apples from different farming systems. The administered apples were grown organically and conventionally under defined conditions and characterised regarding their polyphenol content and antioxidant capacity. No significant differences in the polyphenol content and the antioxidant capacity from the...

Background    Free-range housing, in which pigs have access to both indoor and outdoor areas, is mandatory in organic pig production in Europe, but little is known about the effects of this housing on joint health in pigs. A high level of joint condemnations at slaughter has been reported in organic free-range pigs in Sweden, compared with pigs raised in conventional confined housing. We hypothesised that biomechanical forces imposed on the joints of pigs that range freely promote the development of osteochondrosis and lead to joint condemnation. We compared the prevalence of osteochondrosis and other joint lesions (e.g. arthritis, traumatic) in the elbow and hock joints of 91 crossbred Hampshire (Yorkshire×Landrace) fattening pigs that were housed in a...

Provedor de dados: 21
Autores: Bruun, Sander; Hansen, Trine L.; Christensen, Thomas H.; Magid, Jakob; Jensen, Lars S.
Source separation, composting and anaerobic digestion, with associated land application, are increasingly being considered as alternative waste management strategies to landfilling and incineration of municipal solid waste (MSW). Environmental life cycle  assessments are a useful tool in political decision-making about waste management strategies. However, due to the diversity of processed organic MSW and the situations in which it can be applied, the environmental impacts of land application are very hard to determine by experimental means. In the current study, we used the agroecosystem model Daisy to simulate a range of different scenarios representing different geographical areas, farm and soil types under Danish conditions and legislation. Generally,...

Soil nitrate N as influenced by annually undersown cover crops in spring cereals
Provedor de dados: 21
Autores: Känkänen, Hannu; Eriksson, Christian; Räkköläinen, Mauri; Vuorinen, Martti.
Cover crops can reduce leaching and erosion, introduce variability into crop rotations and fix nitrogen (N) for use by the main crops. In Finland, undersowing is a suitable method for establishing cover crops in cereals. The effect of annual undersowing on soil nitrate N was studied at two sites. Red clover (Trifolium pratense L.), white clover (Trifolium repens L.), a mixture of red clover and meadow fescue (Festuca pratensis Huds.), and westerwold ryegrass (Lolium multiflorum Lam. var. westerwoldicum) were undersown in spring cereals during six successive seasons, and a pure stand of cereal was grown in two years after that. In all years, the soil nitrate N was measured in late autumn, and in addition in different times of the season in last four years....

Aggregate strength and mechanical behaviour of a sandy loam soil under long-term fertilization treatments
Provedor de dados: 21
Autores: Munkholm, Lars J.; Schjønning, Per; Debosz, Kasia; Jensen, Henry E.; Christensen, Bent T.
Current concern for soil quality has stimulated research on soil biological and chemical properties. In contrast, the mechanical behaviour of soil is somewhat neglected. We have examined the effects on soil mechanical properties of more than 100years of contrasting fertilization employing three treatments from the Askov long-term experiment: UNF (unfertilized), NPK (mineral fertilized) and AM (animal manured). We have measured tensile strength of aggregates when air-dry and when adjusted to 10, 30 and 100kPa pressure potential. Four aggregate size classes were investigated (1-2, 2-4, 4-8 and 8-16mm diameter). Soil fragmentation was characterized in the field using a drop-shatter test. Bulk soil strength was determined in the field using a shear vane and a...

Autores: Lauridsen, Charlotte; Vestergaard, Ellen-Margrethe; Højsgaard, Søren; Jensen, Søren K.
This study was designed to investigate the effect of  vitamin E supplementation on vitamin E depots and immune responses in weaned pigs after an E. coli inoculation. The design was a 2×2 factorial with vitamin E supplementation (150 mg/kg RRR-α-tocopheryl acetate versus a control diet containing 60 mg all-rac-α-tocopheryl acetate) and E. coli  0 149 inoculation (inoculation of 1×108 CFU on day 2 and 3 after weaning versus inoculation of vehicle). The pigs were housed individually during the experiment which lasted for 10 days from weaning at 7 weeks of age. Blood was sampled on day 1 (day of weaning) and 9 of the experiment, and serum was analyzed for α-tocopherol concentration. On day 10 of the experiment, pigs were killed and samples of liver, heart,...

The value of catch crops and organic manures for spring barley in organic arable farming
Provedor de dados: 21
Autores: Olesen, Jørgen E.; Hansen, Elly M.; Askegaard, Margrethe; Rasmussen, Ilse A.
The effect of nitrogen (N) supply and weeds on grain yield of spring barley was investigated in an organic farming crop rotation experiment on three different soil types in Denmark from 1997 to 2001. Three experimental factors were included in the experiment in a factorial design: 1) crop rotation (lupin or pea/barley as previous crop to barley), 2) cover crop (with and without), and 3) manure (with and without). The crop rotations included grass-clover as a green manure crop. Animal manure was applied as slurry in rates corresponding to 40% of the N demand of the cereal crops.   Application of 50 kg NH4-N ha-1 in manure (slurry) increased barley grain DM yield by 1.0 to 1.3 Mg DM ha-1, whereas the use of cover crops (primarily perennial ryegrass)...

Chronic Problems of Turkish Farmers
Provedor de dados: 21
Autores: Özbilge, Zeynep.
Turkish farmers who engage in soil cultivation have to face a number of serious problems, ranging from the loss of agricultural land to climate change. Moreover, they cannot earn a living from agriculture due to high production costs, intermediation system in the trade of agricultural products and insufficient financial support. The price increases in chemical fertilizers range from 55% to 82% while the price increase in diesel oil is 47% in the 2010 2014 period. However, the increase in area-based financial support is only 29% in the same period. Therefore, it is required that the state takes all measures to resolve the problems of Turkish farmers. Preventing the misuse of agricultural land as well as its use for non-agricultural purposes, updating...

Provedor de dados: 21
Autores: Paulsen, Hans Marten.
In Versuchen zum ökologischen Mischfruchtanbau von Lein mit Sommerweizen (Triticum aestivum L.), Hafer (Avena sativa L.) oder Leindotter (Camelina sativa L.) wurden die Leinerträge stets deutlich gegenüber den Reinsaatvarianten reduziert. In Sommerweizen waren Leinsamenerträge zwischen 0,1 bis 3,7 dt ha-1 und in Mischung mit Leindotter zwischen 0,7 und 10 dt ha-1 (Trockensubstanz) möglich. In beiden Kulturen konnte der Anteil an Leinsamen im Erntegut durch Absenken der Saatmenge des Mischungspartners erhöht werden. Eine möglichst gleichmäßige Verteilung der Leinsaat als Drillsaat über die Fläche lieferte die höchsten Leinerträge im Mischfruchtanbau. Die Erträge von Sommerweizen oder Leindotter im Mischfruchtanbau waren überproportional hoch verglichen mit...

Autumn applications of sulphur – a new approach to control the pear leaf blister mite Eriophyes pyri.  Abstract: The pear leaf blister mite can cause severe damage to pear leaves and young fruits in some regions. Due to hidden living inside leaf blisters, the mites are largely protected against the impact of plant protecting agents. Until now, treatments with mineral oil or rape oil in early spring, during the time when the mites leave their hibernation sites under the bud scales to invade the young leaves and blossoms, are the only possibility to control these mites in Swiss organic fruit growing. The aim of this study was to examine the effects of sulphur, mineral oil and Surround®WP applied after harvest during the time, when the mites leave their...

Evaluating Research beyond Scientific Impact - How to Include Criteria for Productive Interactions and Impact on Practice and Society
Provedor de dados: 21
Autores: Wolf, Birge; Lindenthal, Thomas; Szerencsits, Manfred; Holbrook, J. Britt; Heß, Jürgen.
Currently, established research evaluation focuses on scientific impact – that is, the impact of research on science itself. We discuss extending research evaluation to cover productive interactions and the impact of research on practice and society. The results are based on interviews with scientists from (organic) agriculture and a review of the literature on broader/social/societal impact assessment and the evaluation of interdisciplinary and ransdisciplinary research. There is broad agreement about what activities and impacts of research are relevant for such an evaluation. However, the extension of research evaluation is hampered by a lack of easily usable data. To reduce the effort involved in data collection,the usability of existing documentation...

Acute toxicity of birch tar oil on aquatic organisms
Provedor de dados: 21
Autores: Hagner, Marleena; Penttinen, Olli-Pekka; Pasanen, Tiina; Tiilikkala, Kari; Setälä, Heikki.
Birch tar oil (BTO) is a by-product of processing birch wood in a pyrolysis system. Accumulating evidence suggests the suitability of BTO as a biocide or repellent in terrestrial environments for the control of weeds, insects, molluscs and rodents. Once applied as biocide, BTO may end up, either through run-off or leaching, in aquatic systems and may have adverse effects on non-target organisms. As very little is known about the toxicity of BTO to aquatic organisms, the present study investigated acute toxicity (LC50/EC50) of BTO for eight aquatic organisms. Bioassays with the Asellus aquaticus (crustacean), Lumbriculus variegatus (oligochaeta worm), Daphnia magna (crustacean), Lymnea sp. (mollusc), Lemna minor (vascular plant), Danio rerio (fish),...

An influence of the intestinal microbiota in connection to first-feeding of rainbow trout (Oncorhynchus mykiss) fry was demonstrated using Illumina HiSeq sequencing. The period from the end of yolk-sac feeding and until seven weeks post first-feeding was examined after administration of either a marine- or plant based diet with or without the probiont Pediococcus acidilactici. Before first feeding the main part of the sequence reads grouped to the genus Sediminibacterium probably originating from the surrounding water. The microbial abundance and diversity increased after first-feeding and the microbiota then changed towards Firmicutes phylum dominance for plant based fed fish and towards dominance of phylum Proteobacteria for the marine fed fish.

Peracetic acids can be used as sanitizers to control water quality in aquaculture systems. As an alternative to   formalin, chloramine-T or copper sulphate, PAA has strong anti-microbial effects, degrades quickly and is relatively safe to use. Its mode of action and associated rapid decay can make optimizing treatment protocols a challenge. Continuous low-dose applications seem to be a   promising solution.

There is an increasing awareness about the need for improving nitrogen use efficiency in crop production in order to meet economic and ecological standards. The present work provides insight into the varietal factors of wheat that determine nitrogen use in the plant. The performance of eleven winter wheat varieties in terms of grain yield and nitrogen uptake and use efficiency was tested within the framework of a 40-year long term field experiment of organic enrichment and mineral nitrogen fertilisation treatments. Globally, organic enrichment had a beneficial effect on the yield and grain nitrogen concentration and showed a strong interaction with the amount of applied mineral nitrogen fertiliser. Manure application generally had positive effects on...

Growing mixtures of species instead of sole crops is expected to increase the ecosystem services provided by cover crops. This study aimed at understanding the interactions between species and investigating how they affect the performance of the mixture. Four species were combined in six bispecific mixtures in a field experiment. The performance of each species when grown in a mixture was compared to its performance as a sole crop at different sowing densities, to characterise the influence of intra- and interspecific competition for each species. Intra- and interspecific competition coefficients were quantified using a response surface design and the hyperbolic yield-density equation. Interactions between the four species ranged from facilitation to...

Økologisk jordbrug dækker over en række forskellige strategier for levevis og produktion. Strukturudvik-ling og øgede bedriftsarealer er en realitet også for økologiske jordbrug, men andre måder til at sikre indtægten er fremherskende for store dele af økologerne.     Herudover foregår der en lang række aktiviteter på bedriften udover selve fødevareproduktionen. Nogle af disse bidrager væsentligt til økonomien, andre har kun en lille økonomisk betydning. De økologiske jordbrug bidrager således til landdistriktsudviklingen, såvel ved sikringen af en fortsat bosættelse på landet, som ved en række aktiviteter, der formentlig kan styrkes ved et fokus på dette.

Spatial and temporal effects of direct drilling on soil structure in the seedling environment
Provedor de dados: 21
Autores: Munkholm, L.J.; Schjønning, P.; Rasmussen, K.J.; Tanderup, K.
Despite more than 30 years of research and practical experience the interest in shallow tillage and especially direct drilling has remained low in Scandinavia. Excessive compaction of the topsoil layer is one of the major problems encountered when adapting shallow tillage and direct drilling in particular. The purpose of this study was to evaluate temporal and spatial effects of two different direct drilling techniques on bulk density and penetration resistance in the near seed environment. A sandy loam growing small grain cereals was followed during the first 3 years after conversion from conventional tillage to direct drilling to reveal short-term changes in soil structure. A field experiment with four blocks was conducted in 1999–2001 where a...

Simulating farm income under the current soil management  regime in the mid-hills of Nepal
Provedor de dados: 21
Autores: Bhatta, G.D.; Neupane, N.
Farmers in the mid-hills of Nepal follow diverse farming  systems. The peri-urban area of this region, where population density is higher, faces several problems in farming. While hills suffer from erosion because they are erodible, the peri-urban areas face the problem of decline in factor productivity, particularly in intensively cultivated farmlands. The present study is concerned with simulating farm income on a regional scale based on soil management practices. Spatial explicit simulation shows that the loss of farm income due to degradation is substantially higher in hills while it is lower in valley bottoms. Strategy formulation and testing in the spatial environment indicates that Geographic Information System is an appropriate methodological tool...

Genetic indications of translocated and stocked grey  partridges (Perdix perdix): Does the indigenous Danish grey partridge (Perdix perdix) still exist?
Provedor de dados: 21
Autores: Andersen, Liselotte Wesley; Kahlert, Johnny.
Non-local population stocking can have adverse genetic  effects through loss of genetic diversity and introgressive hybridisation in wild populations exploited by man. The grey partridge (Perdix perdix) has been an important European game species for centuries, widely subject to translocation and stocking. After ca 80 years releasing reared grey partridges into Danish wild partridge areas, this study investigated whether an indigenous Danish grey partridge still existed. We predicted that (i) an indigenous Danish partridge would belong to the western European clade (W1) and (ii) would be more closely related to the historical, indigenous grey partridges than to farm bred partridges. These predictions were tested analysing the variation in the mitochondrial...

Unwrapping the Northern Sea cheese - Enacting the Sea as terroir
Provedor de dados: 21
Autores: Ostrowski, Kasper.
This paper investigates how a Danish dairy has found an innovative way of making geographical claims by affiliating a regional Danish cheese with the Northern Sea. The Nordic foodscape has, alongside with an increasingly globalized agrifood sector, changed thoroughly over the last decade. Historically, strong geographical claims in relation to food or produce have been less propagated in the Nordic countries, compared to the South. But recently, enactments of quality such as ‘the local’ and the ‘place-specific’ or the ‘endogenous’ and the ‘authentic’ have gained momentum as pivotal notions within the making of markets, not least in Scandinavia. Devoid of well-established traditions for making such geographical claims – new ways of prestige enhancing and...

Organic certification labels from the perspective of consumers in Switzerland
Provedor de dados: 21
Autores: Stolz, Hanna; Moschitz, Heidrun; Janssen, Meike.
Organic labels have been established to communicate the consumer that a certain product has been produced according to defined organic standards. The aim of the research presented in this paper was to investigate i) how Swiss organic consumers perceived different organic labels and ii) if Swiss organic consumers prefer particular organic certification schemes over others. To achieve these objectives, we carried out focus group discussions with organic consumers, and conducted consumer choice experiments  that were combined with a subsequent structured questionnaire. We focused on two labels that are well established in the Swiss market – one mostly in specialised organic shops (Demeter label), the other one also found widely in a larger retail shop (Bio...

Organic Orchard Floor Management Systems for Apple Effect on Rootstock Performance in the Midwestern United States
Provedor de dados: 21
Autores: Stefanelli, Dario; Zoppolo, Roberto J.; Perry, Ronald L.; Weibel, Franco.
In organic apple production systems, orchard floor management is of prime importance because it determines weed management and soil fertility. In this experiment,  we evaluated the response of the cultivar Pacific Gala on three rootstocks of different vigor: M.9 NAKB 337, M.9 RN 29, and Supporter 4 (in respective order of vigor  from dwarfing to semivigorous). The rootstocks were also evaluated for the response to three orchard floor management systems (OFMSs): mulching using alfalfa hay, flame burning, and shallow strip tillage using the Swiss sandwich system (SSS). The experiment was conducted in an experimental orchard planted in 2000.

Screening for Barley Waterlogging Tolerance in Nordic Barley Cultivars (Hordeum vulgare L.) Using Chlorophyll Fluorescence on Hydroponically-Grown Plants
Provedor de dados: 21
Autores: Bertholdsson, Nils-Ove.
Waterlogging can reduce crop yield by 20-50% or more, and lack of efficient selection methods is an obstacle in plant breeding. The methods currently used are mainly indices based on germination ability in Petri dishes and leaf chlorosis in plants grown in waterlogged soils. Cultivation in oxygen-depleted nutrient solution is the ultimate waterlogging system. Therefore methods based on root growth inhibition and on fluorescence in plant material hydroponically grown in oxygen-depleted solution were evaluated against data on biomass growthbiomass accumulation in waterlogged soils. Both traits were correlated with waterlogging tolerance in soil, but since it was easier to measure fluorescence, this method was further evaluated. A selection of F2 plants with...

Phosphorus cycling within soil aggregate fractions of a highly weathered tropical soil: A conceptual model
Provedor de dados: 21
Autores: Garland, Gina; Bünemann, E. K.; Oberson, A.; Frossard, E.; Snapp, S.; Chikowo, R.; Six, J.
Effective use of soil phosphorus (P) for crop production requires an understanding of how P pools are stabilized and cycled within soil aggregates, rather than assuming that P dynamics, particularly organic P, closely follow those of C. The main goal of this study was to compare C and N cycling with P dynamics in soil aggregate fractions under two distinct crop species, maize (Zea mays) and pigeon pea (Cajanus cajan) in a highly-weathered Lixisol. We found that while C and N follow an open cycle, whereby C and N are mineralized from microaggregates during macroaggregate turnover and partially exit the soil system as gas and leachate, P has a relatively closed cycle, where most of the mineralized and solubilized P from microaggregates is lost from the...

Generic calibration of a simple model of diurnal temperature  variations for spatial analysis of accumulated degree-days
Provedor de dados: 21
Autores: Felber, Raphael; Stoeckli, Sibylle; Calanca, Pierluigi.
Accumulated growing degree-days (aGDD) are widely used to predict phenological stages of plants and insects. It has been shown in the past that the best predictive performance is obtained when aGDD are computed from hourly temperature data. As the latter are not always available, models of diurnal temperature changes are often employed to retrieve the required information from data of daily minimum and maximum temperatures. In this study, we examine the performance of a well-known model of hourly temperature variations in the context of a spatial assessment of aGDD. Specifically, we examine whether a generic calibration of such a temperature model is sufficient to infer in a reliable way spatial patterns of key phenological stages across the complex...

Effect of cultural methods on leaf spot (Mycosphaerella fragariae) and gray mold (Botrytis cinerea) damage in strawberries
Provedor de dados: 21
Autores: Schmid, Andi; Daniel, Claudia; Weibel, Franco.
Damage of leaf spot, caused by Mycosphaerella fragariae and gray mold also called Botrytis fruit rot, caused by Botrytis cinerea, average fruit weight and yield were evaluated with regard to cultural methods over two years. Leaf spot damage decreased significantly by around 90 % due to leaf sanitation (removal of dead and leaf spot infected leaves in early spring) and by 50 % due to plantation in a one-row-system instead of a two-row-system. When all leaves including the healthy green ones were removed in early spring average fruit weight decreased significantly by 10 %. Fruit sanitation - the third treatment – did not influence any of the measured parameters.   Neither leaf sanitation nor fruit sanitation (removal of damaged fruits during harvest) reduced...

Does organic supply growth leads to reduced price premiums? The case of salmonids in Denmark1
Provedor de dados: 21
Autores: Ankamah-Yeboah, saac; ielsen, Max; Nielsen, Rasmus.
Consumers buy organic products to increase utility, while farmers invest in organic production to achieve price premiums. However, investors would like to avoid the risk of falling prices when organic supply increases to maintain profit. We suggest the use of market integration tests between non-stationary price series of organic/conventional products to reveal whether increasing organic supply can be expected to reduce price premiums. Increased organic supply will induce price falls if organic/conventional markets are independent. Organic supply growth will leave price premiums unchanged, if prices move together over time, since conventional supply typically is larger than organic. The method is applied to the Danish market for farmed salmonids....

Knowledge about the role of microorganisms in P cycling at conditions of constant soil respiration rates and constant size of microbially bound P is lacking. To study the kinetics of microbial P uptake and cycling under such conditions, soils differing in biological activity were 33PO4 labelled by introducing a carrier-free tracer solution and incubated for 56 days. The 33PO4 incorporation into the fraction of microbial P releasable by chloroform treatment (Pchl) was assessed and the isotopic composition [=specific activity (SA); SA=33PO4/31PO4] of Pchl and soil solution P compared. Soils were taken from a 20-year-old field experiment including a nonfertilised control (NON), a minerally fertilised conventional (MIN) and two organic farming systems...

Sow body condition at weaning and reproduction performance in organic piglet production
Provedor de dados: 21
Autores: Kongsted, A.G.; Hermansen, J.E.
The objective was to investigate the variation in backfat at weaning and its relations to reproduction results in organic sow herds in Denmark. The study included eight herds and 573 sows. The average backfat at weaning mean�13 mm; SD�4.2 mm) ranging from 10.5 to 17.3 mm among herds shows that it is possible to avoid poor body condition at weaning even with a lactation length of seven weeks or more. No main effect of backfat at weaning on reproduction performance was found, but the probability of a successful reproduction after weaning tended to decrease with decreasing backfat for first parity sows, whereas the opposite was the case for multiparous sows.

Food chains in cereal fields
Provedor de dados: 21
Autores: Bruus Pedersen, M.; Axelsen, Jørgen Aagaard; Tybirk, Knud.
Correlations between the weed flora and the arthropod fauna of conventionally and organically managed fields were analysed. The results indicate that the abundance of weeds in Danish conventionally grown cereal fields is too low to sustain a population of more or less species specific herbivores, i.e. too low to maintain functioning food chain links between weeds and herbivores. Organically grown fields with a higher abundance of weeds may be capable of sustaining a fauna of arthropods relying on the weeds. The data from extra- weedy areas support this hypothesis, indicating that particularly weed-rich fields can better support herbivorous insects.

Organic pig husbandry systems in Europe are diverse – ranging from indoor systems with concrete outside run (IN) to outdoor systems all year round (OUT) and combinations of both on one farm (POUT). As this diversity has rarely been taken into account in research projects on organic pig production, the aim of this study was to assess and compare pig health, welfare and productivity in these three systems. Animal health and welfare were assessed using direct observation and records of 22 animal-based measures, comprising 17 health-, 3 productivity- and 2 behavioural measures. These were collected in pregnant sows, weaners and fattening pigs during direct observations and from records within a cross-sectional study on 74 farms (IN: n=34, POUT: n=28, OUT:...

Autores: Panneerselvam, P.; Hermansen, J.E.; Halberg, N.; Arthanari, P.M.
The millions of food insecure people in India are not solely due to inadequate food production, but also because some people are simply too poor to buy food. This study assessed how a large-scale conversion from conventional to organic production would impact on the economics of marginal and small farmers in Tamil Nadu and Madhya Pradesh, and on the total food production in these states. This study also considered a situation where fertilizer subsidies would be discontinued, with farmers having to carry the full cost of fertilizer. Results show that conversion to organic improved the economic situation of farmers although food production was reduced by 3–5% in the organic situation. Thus, the estimated economic values were higher in the organic system...

Do the new organic producers differ from the 'old guard'? Empirical results from Norwegian dairy farming
Provedor de dados: 21
Autores: Flaten, Ola; Lien, Gudbrand; Ebbesvik, Martha; Koesling, Matthias; Valle, Paul Steinar.
Conventional farmers converting to organics have contributed to most of the rapid expansion of organic farming in recent years. The new organic farmers may differ from their more established colleagues, which may have implications for the development of the organic farming sector and its distinctiveness vis-a`-vis conventional production and marketing practices. The aim of this study was to explore Norwegian organic dairy farmers’ personal and farm production characteristics, farming goals, conversion motives, and attitudes to organic farming,  grouped by year of conversion (three groups). A postal survey was undertaken among organic dairy farmers (n = 161). The results show that the newcomers (converted in 2000 or later) were less educated than the early...

Autores: Kendall, H.; Naughten, P.; Kuznesof, S.; Raley, M.; Dean, M.; Clark, B.; Stolz, H.; Home, R.; Chang, M. Y.; Zhong, Q.; Brereton, P.; Frewer, L. J.
Background/Aims  Persistent incidents of food fraud in China have resulted in low levels of consumer trust in the authenticity and safety of food that is domestically produced. We examined the relationship between the concerns of Chinese consumers regarding food fraud, and the role that demonstrating authenticity may play in relieving those concerns.  Methods  A two-stage mixed method design research design was adopted. First, qualitative research (focus groups n = 7) was conducted in three Chinese cities, Beijing, Guangzhou and Chengdu to explore concerns held by Chinese consumers in relation to food fraud.

a framework for estimating the scientific impact of these  studies. Furthermore, the problems connected with the different research approaches are being discussed. A number of comparative studies showed lower nitrate contents and less pesticide residues, but usually higher levels of vitamin C and phenolic compounds in organic plant products, as well as higher levels of omega-3 fatty acids and conjugated linoleic acid in milk from organically raised animals. However, the variation in outcomes of comparative   studies is very high, depending on plant fertilization, ripening stage and plant age at harvest, and weather conditions. Moreover, there appeared no simple relationship between nutritional value and health effects. It is difficult therefore to draw...

Grassland carbon sequestration and emissions following cultivation in a mixed crop rotation
Provedor de dados: 21
Autores: Acharya, B.S.; Rasmussen, J.; Eriksen, J.
Grasslands are potential carbon sinks to reduce unprecedented increase in atmospheric CO2. Effect of age (1 to 4-yr-old) and management (slurry, grazing multispecies mixture) of a grass phase mixed crop rotation on carbon sequestration and emissions upon cultivation was compared with 17-yr-old grassland and a pea field as reference. Aboveground and root biomass were determined and soils were incubated to study CO2 emissions after soil disturbance. Aboveground biomass was highest in 1-yr-old grassland with slurry application and lowest in 4-yr-old grassland without slurry application. Root biomass was highest in 4-yr-old grassland, but all 1 to 4-yr-old grasslands were in between the pea field (0.81±0.094 g kg-1 soil) and the 17-yr-old grassland (3.17±0.22...

Autores: Hagner, Marleena; Pasanen, Tiina; Lindqvist, Bengt; Lindqvist, Isa; Tiilikkala, Kari; Penttinen, Olli-Pekka; Setälä, Heikki.
The use of birch tar oil (BTO) is a new innovation in plant and animal protection working against various weeds, harmful insects and rodents. Due to its novelty as a biocide/repellent/plant protection product, no comprehensive information on the effects of BTO on non-target soil organisms is available. In this study we examined the impact of BTO on non-target soil organisms (enchytraeids, nematodes and soil microbes) and plants using laboratory toxicity tests and field experiments. In addition, we determined the LC50 value of BTO to the earthworm Aporrectodea caliginosa and the EC50 value of BTO to the offspring production of the collembolan Folsomia candida. The effects of BTO on soil fauna were mostly insignificant. BTO seemed to be detrimental to the...

Quality traits are highly focused upon in the marketing of organic food products. There is a need to define and measure quality as consumers seem to have preconceived notions about the superior health value and taste of organic compared to non-organic products. A commonly held opinion among many consumer groups is that organic farming guarantees optimum quality, despite the fact that this remains unproven. The aim of this paper is to contribute to a better understanding of the complexity of quality traits in a plant-based food product, using carrots as an example. Selected designated quality aspects are presented to describe the complexity of quality and discuss the challenges of using these aspects in differentiating between organic and conventional...

Alternativen zur Anwendung von Kupfer als Pflanzenschutzmittel [Alternatives for copper application as plant protection products]
Provedor de dados: 21
Autores: Schleuß, Uwe.
Zusammenfassend lässt sich nach dem 7. Fachgespräch "Pflanzenschutz im ökologischen Landbau" in Berlin resümieren, dass zur Zeit auf den Einsatz von Kupfer als Pflanzenschutzmittel im ökologischen Landbau noch nicht verzichtet werden kann. Um die Umweltauswirkungen so gering wie möglich zu halten, ist eine Minimierung der Aufwandmenge anzustreben. Dabei muss natürlich die fungizide Wirkung erhalten bleiben. Ein Durchbruch beim Ersatz von kupferhaltigen Pflanzenschutzmitteln ist hinsichtlich Wirksamkeit und Kontinuität noch nicht gegeben. Daher ist zunehmend mehr Wert auf Präventionsmaßnahmen zu legen, z. B. Anbau resistente Sorten.

Short-term nitrous oxide emissions from pasture soil as influenced by urea level and soil nitrate
Provedor de dados: 21
Autores: Petersen, Søren O.; Stamatiadis, Stamatis; Christofides, Calliopi.
Nitrogen excreted by cattle during grazing is a significant source of atmospheric nitrous oxide (N2O). The regulation of N2O emissions is not well understood, but may vary with urine composition and soil conditions. This laboratory study was undertaken to describe short-term effects on N2O emissions and soil conditions, including microbial dynamics, of urea amendment at two different rates (22 and 43 g N m-2). The lower urea concentration was also combined with an elevated soil NO3- concentration. Urea solutions labelled with 25 atom% 15N were added to the surface of repacked pasture soil cores and incubated for 1, 3, 6 or 9 days under constant conditions (60% WFPS, 14°C). Soil inorganic N (NH4+, NO2- and NO3-), pH, electrical conductivity and dissolved...

Schwefelgehalte, Proteinfraktionen und Kleberzugfestigkeit von Weizen – Ergebnisse eines Ringversuchs biologisch-dynamischer Züchter
Provedor de dados: 21
Autores: Hagel, Ingo; Haneklaus, Silvia; Schnug, Ewald.
Schwefelmangel führt bei Weizen zu erheblich festeren Teigen. Daher kollidierte in den 80er Jahren unvorhergesehen das Zuchtziel einer Steigerung der Backqualität durch eine Straffung der Proteinstruktur mit einer exogen bewirkten zusätzlichen Verfestigung der Proteinmatrix infolge drastisch reduzierter Schwefeleinträge in die Ökosysteme. Eine S-Düngung führte dann auch zu einer Steigerung des Backvolumens. Und zwar nicht weil die Kleber der modernen Weizensorten zu weich, sondern weil sie durch die Züchtung bereits zu stark verfestigt waren und den neuen Umweltverhältnissen nicht mehr angepasst waren. Die hohe technologische Qua-lität dieser Sorten kann daher als Resultat eines züchterisch unbewusst induzierten S-Mangels angesehen werden, denn sie weisen...

Abstract For low-input crop production, well-characterised varieties increase the possibilities of managing diseases and weeds. This analysis aims at developing a framework for analyzing grain yield using external varietal information about disease resistance, weed competitiveness and yield potential and quantifying the impact of susceptibility grouping and straw length scores (as a measure for weed competitiveness) for predicting spring barley grain yield under variable biotic stress levels. The study   comprised 52 spring barley varieties and 17 environments, i.e., combinations of location, growing system and year. Individual varieties and their interactions with environments were analysed by factorial regression of grain yield on external variety...

The influence of policy networks on policy output. A comparison of organic farming policy in the Czech Republic and Poland
Provedor de dados: 21
Autores: Moschitz, Heidrun; Stolze, Matthias.
Although, at the time of accession to the EU, organic farming policies formally were equally developed in the Czech Republic and Poland, a closer investigation reveals some variation. This paper takes a policy network perspective to explore the policy differences between these two countries. Common network themes are used to link networks with policy output. It is argued that the capacity of the organic sector and its structural organization, its cohesion, and the relationship between organic interest groups and the government affect the political discourse, and, in consequence, how organic farming policy is elaborated.

Valuing international marine resources: A meta-analysis on the Baltic Sea
Provedor de dados: 21
Autores: Ahtiainen, Heini.
The study uses meta-analysis to provide insights into the value of international marine resources, illustrating the issue with the case of the Baltic Sea. Willingness to pay for water quality improvements varies systematically with factors such as a country's income level, characteristics of the change in water quality, water body type, study year and methodology. The results of the meta-analysis are applied to benefit transfer in order to assess the distribution of the benefits of marine protection measures between the Baltic Sea countries and to compare the results with previous research. The net benefits of protecting the Baltic are positive, but they are asymmetrically distributed between the littoral countries.

Autores: Berntsen, J.; Petersen, B.M.; Olesen, J.E.; Eriksen, J.; Søegaard, K.
The FASSET farm model was used to simulate production in an experiment where a grass-clover or a grass ley was either cut or grazed with dairy cows receiving low or high N sup-plements. The six different ley types were ploughed in and followed by three years with spring cereals with undersown catch crops.   The original model was extended with a new grass and clover model, which included the capability to simulate rhizodeposition and root growth. The new model predicted the observed annual carbon (C) and nitrogen (N) production satisfactorily. The simulated first year residual effects of a cut grass or grass-clover ley varied between 0 and 34, while the residual effect of a grazed grass or grass-clover ley varied between 71 and 150 fertilizer equivalents...

Autores: Nelson, Erin; Schwentesius, Rita; Tovar, Laura Gómez; Cruz, Manuel Gómez.
Over the past several years, in response to the rapid growth in global demand for organic goods, the amount of organic production in Mexico has increased dramatically. Indeed, while Mexican agriculture as a whole has suffered severe crises, the organic sector has boomed, and today more than 83 000 producers farm organically on over 300 000 hectares of land. Of these producers, 98 percent are small scale, farming an average of three hectares, and over 50 percent are indigenous people. Unfortunately, as is the case in many developing countries, the vast majority of organic production remains focused on export crops – particularly coffee, but also cocoa, coconut, and other fruit and vegetables – with 85 percent of organic goods being sent to foreign markets....

Practical implications of increasing 'natural living' through suckling systems in organic dairy calf rearing
Provedor de dados: 21
Autores: Wagenaar, Jan-Paul; Langhout, Jos.
The introduction of suckling systems in organic dairy calf rearing has the potential to enhance animal welfare in  terms of ‘natural living’ and to live up to consumers’ expectations about organic agriculture. This study describes the implications of suckling systems in a practical organic dairy context. Results show that farmers can successfully develop and implement a suckling system in calf rearing. The consumption of mothers’ milk resulted in high weaning weights at 3 months of age. No immediate animal health problems linked to suckling systems occurred. Compared with traditional bucket feeding of milk, suckling systems resulted in increased natural behaviour such as calf cow bonding, natural sucking behaviour and care-taking behaviour. Some farmers...

Autores: Rangstrup-Christensen, Lena; Schild, Sarah-Lina Aagaard; Pedersen, L.J.; Sørensen, Jan Tind.
The aims of the current study were to identify the causes of preweaning piglet mortality and investigate the effect of season and parity on the proportions of mortality causes. The study was conducted in nine herds over a one-year period, and dead piglets were collected for necropsy once during each of the four seasons. In total, 2672 piglets were necropsied of which 60% were live-born but died post-partum (pp), 32% were stillborn and 8% were euthanised. Intra-partum deaths accounted for 88% of stillborn piglets. Eighty-one percent of necropsied live-born piglets died within four days pp. Half of these had a body weight of &lt;1 kg at the time of death. Crushed and starved piglets accounted for 83% and 9% of mortalities until day four pp, respectively....

Organic sheep breeding on the Causse Méjan: challenges and drawbacks of organic breeding in a national park in France
Provedor de dados: 21
Autores: BLANC, J.
This work highlights the ecological stakes and the drawbacks associated with the development of organic lamb production on the Causse Méjan, a calcareous plateau, part of which is included in the Cévennes National Park (PnC). It analyses the tensions underlying a valorisation project for organic lambs by a small group of stockbreeders that is supported by the national park because of the ecological quality of their practices. On the one hand, since breeders are highly dependent on the ecological characteristics of the environment, they are forced to multiply their marketing channels and to invest a great deal of energy to obtain good prices for their meat whose characteristics do not match the current standards of quality (homogeneity, clear meat). On the...

Land transformation to adapt fields to mechanization in perennial crop farming is a common practice which includes land levelling, deep ploughing, stone-breakage and clearing, application of fertilizers and amendments. Manipulation of the natural soil profile along its entire depth can severely disturb the naturally existing chemical  physical,biological and hydrological equilibrium (Costantini and Barbetti, 2008; Costantini et al., 2013). The most common effects of the land transformation are mixing of soil horizons and soil truncation, which result in reduction of soil depth and available water, organic matter depletion, enrichment of calcium carbonate content in the topsoil,imbalance of some element ratio, and decline in the activity and diversity of...

Effect of bioactive compounds from Sainfoin (Onobrychis viciifolia Scop.) on the in vitro larval migration of Haemonchus contortus: role of tannins and flavonol glycosides
Provedor de dados: 21
Autores: E., BARRAU; N., FABRE; I., FOURASTE; H., HOSTE.
Anthelmintic bioactivity against gastrointestinal nematodes has been associated with leguminous forages supporting the hypothesis of a role of condensed tannins. However, the possibility that other compounds might also been involved has received less consideration. Using bio-guided fractionation, the current study aimed at characterising the biochemical nature of the active compounds present in sainfoin (Onobrychis viciifolia), previously identified as an  anthelmintic leguminous forage. The effects of sainfoin extracts were evaluated on 3rd stage larvae (L3) of Haemonchus contortus by using a larval migration inhibition (LMI) assay. Comparison of extracts obtained with several solvent systems showed that the bioactivity was associated with the 70:30...

Effects of green manure storage and incorporation methods on nitrogen release and N2O emissions after soil application
Provedor de dados: 21
Autores: Carter, Mette S.; Sørensen, Peter; Petersen, Søren O.; Ma, Xiuzhi; Ambus, Per.
More efficient use of green manure-derived nitrogen (N) may improve crop yields and reduce environmental impacts in stockless organic arable farming. In this 3-month incubation study, we tested a new strategy where green manure leys are harvested and preserved until the following spring either as compost mixed with straw or as silage of harvested ley biomass. Grass-clover compost or silage was soil-incorporated by either simulated ploughing (green manure placed at 15 cm depth) or harrowing (green manure mixed into the upper 5-cm soil horizon) in order to assess treatment effects on net release of plant-available N, nitrous oxide (N2O) fluxes, and soil respiration. Grass-clover silage provided the highest net N release with similar results for the two...

Plant-availability of catch crop S following spring incorporation
Provedor de dados: 21
Autores: Eriksen, J.; Thorup-Kristensen, K.; Askegaard, M.
Catch crops might reduce sulphate leaching and thereby increase the overall S use efficiency in crop rotations. At 2 experimental sites in Denmark (a sandy loam and a coarse sand) S uptake of catch crop species was measured. Furthermore net release of S following incorporation of this material  (S contents 0.13-1.03%, C:S ratios of 40-329 and lignin content of 1-10.8%) was investigated in a pot experiment with spring barley in sandy soil. The catch crops showed huge differences in their ability to sequester S. The best catch crops (legumes on sandy loam), sequestered 10-12 kg S ha-1 and the poorest catch crops (ryegrass and sorrel on coarse sand), sequestered less than 3 kg S ha-1. The S mineralisation rates were highest for crucifers (57-85% of total S...

Soil organic phosphorus forms under different soil management systems and winter crops, in a long term experiment
Provedor de dados: 21
Autores: TIECHER, T.; SANTOS, D.R.; CALEGARI, A.
Organic phosphorus (P) is an important source of phosphate for plants both in natural environments and in cultivated soils. Growing plants with high P recycling capacity may increase the importance of organic forms in phosphate availability mainly in undisturbed soils. The aim of this study was to evaluate the effect of long period of cultivation of different winter species under different soil management systems in the distribution of soil organic P forms, in the P content stored into the soil microbial biomass (SMB) and in the acid phosphatase enzyme activity. The experiment was established in 1986 with six winter treatments (blue lupine, hairy vetch, oat, radish, wheat and fallow) implanted in a Rhodic Hapludox in southern Brazil, under no-tillage...

Effect of organic grass-clover silage on fiber digestion in dairy cows
Provedor de dados: 21
Autores: Naadland, Sondre Stokke; Steinshamn, Håvard; Krizsan, Sophie Julie; Randby, Åshild T.
There are differences in grass-clover proportions and chemical composition between herbage from primary growth (PG) and regrowth (RG) in grass-clover leys. Mixing silages made from PG and RG may provide a more optimal diet to dairy cows than when fed separately. We tested the hypotheses that increasing dietary proportions of grass-clover silage made from RG compared with PG would increase digestion rate of potentially degradable NDF (pdNDF), and increase ruminal accumulation of indigestible NDF (iNDF). Eight rumen cannulated Norwegian Red cows were used in two replicated 4×4 Latin squares with 21-day periods. Silages were prepared from PG and RG of an organically cultivated ley, where PG and RG silages were fed ad libitum in treatments with RG replacing PG...

Biodiversity recovery and transformation impacts for wetland biodiversity
Provedor de dados: 21
Autores: Pezzati, L.; Verones, F.; Curran, M.; Baustert, P.; Hellweg, S.
Life Cycle Assessment (LCA) methods for land use take both occupation and transformation impacts into account. However, for wetlands and impacts from water consumption, it is so far not possible to account for transformation impacts. It is our goal to close this research gap, by determining wetland recovery times and developing characterization factors for transformation. To do this, we conducted ameta-analysis of 59 studies analyzing biodiversity recovery in wetlands subject 20 to passive and active restoration. Generalized linear models were fitted to the biodiversity data and age, along with other wetland characteristics (such as elevation, latitude or climate class), were used as predictor variables. The results indicate that elevation, latitude, type...

Optimierter Backtest für praxisrelevante Mehlbeurteilung – am Beispiel von Ökoweizen
Provedor de dados: 21
Autores: Linnemann, Ludger.
In jüngster Zeit wurden Weizensorten aus ökologischer Züchtung mit hohen Kleberqualitäten eingeführt, die zunehmend an Marktbedeutung gewinnen. Mit den bisher üblichen, in der Praxis etablierten Backversuchen, wie dem Rapid-Mix-Test (RMT) werden jedoch potenzielle Backeigenschaften von Weizenmehlen vielfach unterbewertet. Zu diesem Ergebnis kommt ein Forschungsvorhaben, gefördert im Rahmen des Bundesprogramms Ökologischer Landbau und andere Formen nachhaltiger Landwirtschaft (BÖLN). Mithilfe eines optimierten Backtests, der im Forschungsring e. V. für biologisch-dynamische Wirtschaftsweise in Darmstadt unter Leitung von Dr. Ludger Linnemann entwickelt wurde, ist ein zuverlässiger Nachweis der potenziellen Verarbeitungsqualität gelungen: Der optimierte...

Atlas of Organics: Four maps of the world of organic agriculture
Provedor de dados: 21
Autores: Paull, John; Hennig, Benjamin.
This paper presents four maps of the world of organic agriculture. Density equalising maps (cartograms) have previously been published of the world of organic agriculture based on the reported hectares of certified organically managed agriculture land. The four maps in the present atlas of organic agriculture are visual presentations of current global organics data: (a) certified organic agriculture hectares; (b) certified organic wildculture hectares; (c) total certified organic production hectares (organic agriculture plus wildculture plus forestry plus aquaculture); (d) certified organic producers. Australia dominates in the world map of the organic agriculture hectares, Europe is strongly represented, and Africa is weakly represented. Finland dominates...

Feed nitrogen conversion in lactating dairy cows on pasture as affected by concentrate supplementation
Provedor de dados: 21
Autores: Steinshamn, Håvard; Höglind, Mats; Garmo, Torstein H; Thuen, Erling; Brenøe, Ulrik Tutein.
The effect of concentrate supplementation on nitrogen (N) intake and excretion in grazing lactating dairy cows was determined in three herds in Norway. Grazing trials were conducted with each herd in June and August for two consecutive years. The average supplementation was 1.8 (S.D. 2.1) kg DM/day, and the concentrate was based on grain with a N content ranging from 18.7 to 24 g/kg DM. Herbage DM and N intake were reduced with increasing supplementation, but total DM and N intake increased. Milk yield and protein content increased by 1.1 kg milk and 0.28 g protein per kg milk for each kg extra concentrate. Milk N excretion increased with increasing supplementation (6.5 g N/kg DM), and N utilisation improved by 11.7 g N per kg N intake per kg extra...

Real-time PCR to quantify composition of arbuscular mycorrhizal fungal communities - marker design, verification, calibration and field validation
Provedor de dados: 21
Autores: Thonar, C.; Erb, A.; Jansa, J.
Quantitative real-time PCR (qPCR) is slowly becoming established as a tool to quantify abundance of different arbuscular mycorrhizal fungal (AMF) taxa in roots and in soil. Here, we describe the development and field validation of qPCR markers (i.e. primers with associated hydrolysis probes), targeting taxon-specific motifs in the nuclear large ribosomal subunit RNA genes. Design of such markers is complicated by the multinuclear and multigenomic cellular organization of these fungi and the high DNA sequence diversity within the smallest biologically relevant units (i.e. single-spore isolates). These limitations are further compounded by inefficient biomass production of these fungi, resulting in limited availability of pure genomic DNA (gDNA) of...

Tailoring bilberry powder functionality through processing: effects of drying and fractionation on the stability of total polyphenols and anthocyanins.
Provedor de dados: 21
Autores: Oliveira, Gabriel; Eliasson, Lovisa; Ehrnell, Maria; Höglund, Evelina; Andlid, Thomas; Alminger, Marie.
Bilberries are a rich natural source of phenolic compounds, especially anthocyanins. The press cake obtained during the processing of bilberry juice is a potential source of phytochemicals. The objective of this study was to evaluate different drying techniques and the fractionation of bilberry press cake powder toward obtaining phenolic-rich ingredients for incorporation into value-added food products. The derived powders were dispersed in water and dairy cream, to investigate the effects of drying and fractionation on the dispersibility and solubility of phenolic compounds. The drying techniques, hot air drying and microwave drying, applied on bilberry press cake reduced the content of total phenolics and anthocyanins. The degradation was, however,...

Provedor de dados: 21
Autores: Zazo, Francisco Eduardo; Flores, Claudia Cecilia; Sarandon, Santiago Javier.
El Partido de Arrecifes, ubicado en la Región Pampeana, ha sufrido un proceso de “sojización” intenso en los últimos 20 años, por la mayor rentabilidad de este cultivo, que podría haber conducido a balances de nutrientes negativos y pérdida de carbono (C) de los suelos. Esta degradación del capital natural, implicaría un “costo oculto” que no ha sido tenido en cuenta. El objetivo de este trabajo fue cuantificar esta degradación del suelo y expresarla en valores físicos y valores monetarios. Los fertilizantes alcanzaron a cubrir solo parcialmente lãs extracciones de nutrientes realizadas por la soja, maíz y trigo, por lo que los balances de N, P, K, Ca, Mg y S de la Región fueron negativos todos los años. La soja fue responsable del 83%, 89%, 91%, 95%, 75%...

Organic farming: The arrival and uptake of the dissident agriculture meme in Australia
Provedor de dados: 21
Autores: Paull, John.
Just four years elapsed between the coining of the term ‘organic farming’ and the founding of an association devoted to the advocacy of organic farming. The world’s first association devoted to the promotion and proliferation of organic agriculture, the Australian Organic Farming and Gardening Society (AOFGS), was founded in Sydney, Australia, in October 1944. It is a geographically surprising sequel to the coining of the term ‘organic farming’ by Lord Northbourne and its first appearance in war-time Britain. Northbourne’s manifesto of organic farming, Look to the Land, was published in London in May 1940. When the AOFGS published a periodical, the Organic Farming Digest, it was the first association to publish an organics advocacy journal. The present...

Effects of extra floral and floral nectar of Centaurea cyanus on the parasitoid wasp Microplitis mediator: Olfactory attractiveness and parasitization rates
Provedor de dados: 21
Autores: Géneau, Céline E.; Wäckers, Felix L.; Luka, Henryk; Balmer, Oliver.
Nectar is an important food source for adult parasitoids and can increase their longevity and fecundity and hence their parasitization rate. Both floral and extrafloral nectar are used as food sources by parasitoids. While floralnectar exploitation by parasitoids has been extensive lystudied, little is known on how parasitoid slocate extrafloral nectar,nor whether the availability ofextrafloral nectar increases parasitization of pests in the field. We conducted aY-tube olfactomete rexperiment to determine if the parasitoid Microplitis mediator utilizes olfactory cues tolocate the extrafloral nectar of Centaurea cyanus. Inaddition, weperformed asemi-fieldexperiment to investigate whether M.mediator are differentially attracted by C.cyanus offering...

100 % organic feeding for monogastrics is a challenge for poultry value chain and feed industry. 100 % organic diets without including conventional protein concentrate is a challenge : this might increase the importation of organic proteins (soya) and involve risk on technical and economical performances.  This article is a synthesis of different research projects lead in France and in Europe. Nutritional value of organic raw material is highly variable, especially oleaginous meal (whatever the process). Increasing knowledge about nutritional value of organic raw material is needed to support 100 % organic feeding. Even if different organic raw material could be used in diets, this material is not sufficiently available with regard to their quantity...

Spring cereals: from dynamic ideotypes to cultivars in Northern latitudes
Provedor de dados: 21
Autores: Mäkelä, Pirjo; Muurinen, Susanna; Peltonen-Sainio, Pirjo.
The ideotype of a crop is a model of a plant community where all necessary and beneficial traits for crop performance in a particular environment are combined. It is important to consider the environment when developing an ideotype since climatic, edaphic and agronomic features of the target region have a major role in determining crop performance. New technologies, high yielding cultivars, irrigation and water management, plant protection materials and more skilful farm management practices have increased yields and yield potentials on cereals in Finland as in many other countries. In this paper we aim to summarize traits which would be useful from the farmers’ perspective. The most important trait is increased early vigour of spring cereals, including...

Physical fractionation of soil and structural and functional complexity in organic matter turnover
Provedor de dados: 21
Autores: Christensen, B.T.
Physical fractionation is used increasingly to study the turnover of organic matter in soil.  This essay links the methods of fractionation to concepts of turnover by defining levels of structural and functional complexity that refer to experimentally verifiable pools of organic matter in the soil.   Physical fractionation according to size and density of soil particles emphasizes the importance of interactions between organic and inorganic soil components in the turnover of organic matter.  It allows the separation of free and occluded uncomplexed organic matter and of primary and secondary organomineral complexes.  This methodological approach recognizes that the overall regulation of decomposer activity is through the structure of soil, which determines...

Agronomic characteristics of the spring forms of the wheat  landraces (einkorn, emmer, spelt, intermediate bread wheat)  grown in organic farming
Provedor de dados: 21
Autores: Konvalina, Petr; Capouchova, Ivana; Stehno, Zdenek; Moudry, Jan.
Organic farmers look to the possibilities of growing neglected crops, such as the spring forms of hulled wheat – einkorn, emmer and spelt – for support in developing the organic farming system. In 2008, 169 landraces from the gene bank at the Crop Research Institute in Prague were tested on certifi ed organic plots. The experiment was aimed at fi nding suitable varieties for the organic farming system. In summary, our fi ndings show that einkorn (Triticum monococcum L.) and emmer wheat [Triticum dicoccum Schrank (Schuebl)] are resistant to powdery mildew and brown rust, spelt wheat (Triticum spelta L.) is less resistant to these two diseases, and the intermediate forms of bread wheat are very sensitive to such infestation.

In repeatedly mown and mulched green manure leys, the mulched herbage contains substantial amounts of nitrogen (N), which may only slightly contribute to the following crops’ nutrient demand. The objective of the present work was to evaluate the effect of alternative strategies for green manure management on the yield and N recovery of a subsequent spring barley crop, and their short term effects on soil structure and earthworm populations. A field trial was run from 2008 to 2011 at four sites with contrasting soils under cold climate conditions. We compared several options for on-site herbage management and the application of anaerobically digested green manure herbage. Depending on the site, removal of green manure herbage reduced the barley grain yield...

Dispersal and habitat quality as constraining factors for herbaceous forest species in an ancient hedgerow network
Provedor de dados: 21
Autores: Stidsen, A.N.; Tybirk, K.
Reports on the importance of hedgerows for conservation of vulnerable herbaceous forest (HF) species are conflicting. The main objective of the present study was to throw light on the possible role of hedgeworks functioning as dispersal corridors for HF species. Seventy-four plots were laid out in a hedgerow network close to ancient woodlands. A total of 30 HF species were found. Richness and cumulated frequency of HF species as well as the frequencies of six selected forest herb species were compared with hedgerow age, width, distance to woodland and weighted Ellenberg indicator values for light, soil moisture, soil pH and soil fertility. Distance to woodland followed by light and soil moisture were the most important explanatory variables of HF species...

Autores: Kühn, B.F.; Lindhard Pedersen, H.
To investigate the optimal growing system for organic apple production three different cover crop management systems were established for two scab resistant varieties. Treatment 1: A permanent grass mixture in the alleyway. Treatment 2: A permanent clover grass mixture in the alleyway and treatment 3: An annual mixture of grass and clover was sown every year in July and mulched down the next year in April. Mechanical weed cleaning was done from April to July. Mechanical weeding was carried out in the tree row and no additional fertilizing and pest disease control were carried out. Effects of soil treatment on nutrient supply and fruit quality was investigated.

Influence of grouping strategy on welfare measurements of organic entire male pigs
Provedor de dados: 21
Autores: Thomsen, Rikke; Rousing, Tine; Edwards, Sandra A; Labouriau, R.; Sørensen, Jan Tind.
Alternatives to surgical castration in organic pig production are needed, due to stress and pain caused by castration of male pigs. One alternative, which is in accordance with the values in organic farming, is production of entire male pigs. However, changed behaviour of entires compared to castrates might affect the welfare of the animals. Therefore, in order to produce entire male pigs, without compromised animal welfare, changes in the production system, possible offered by the organic farming system, with e.g. more available space and access to rooting material and roughage, might be a necessity. The aim of this article is to investigate the effect of grouping strategy and group size on levels of mounting behaviour and skin lesions, hypothesising that...

Phyto-oestrogens in herbage and milk from cows grazing white clover, red clover, lucerne or chicory-rich pastures
Provedor de dados: 21
Autores: Andersen, Charlotte; Nielsen, Tina Skau; Purup, Stig; Kristensen, Troels; Eriksen, Jørgen; Søegaard, Karen; Sørensen, John; Fretté, Xavier C.
A grazing experiment was carried out to study the concentration of phyto-oestrogens in herbage for cattle and in milk during two periods (May and June). Forty-eight Danish Holstein cows were divided into four groups with four treatment diets; white clover, red clover, lucerne and chicory-rich pastures. Each experimental period lasted 15 days. Herbage samples from the first day and individual milk samples from the last day of the experimental period were analysed for phyto-oestrogens using LC-MS technique. The total concentration of phyto-oestrogens was 21 399 mg/kg DM for red clover and 238-466 mg/kg DM for the other three herbages mainly due to a much higher concentration of biochanin A, formononetin and glycitein in red clover. In the milk, the total...

Organic farming on grasslands
Provedor de dados: 21
Autores: Moudry, Jan (Jr.); Friebel, Ludvik; Konvalina, Petr; Friebelova, Jana.
Sustainable agriculture has currently been considerably supported by the EU which positively affects development of organic farming in EU member states.  Along with expansion of organic farming itself, importance of its production and non-production function rises as well. Both these functions are expected to be mutually balanced so as the organic farms were not focused on one-sided production. To reach such balance the grant programmes should be suitably set so that the farms were motivated to farm on arable land and permanent grasslands on one side and fulfil non-production function of agriculture on the other side as well. The balance of grant programmes can be estimated according to the way how organic farming is carried on. This article is focused on...

Evaluating and regulating the impacts of lobbying in the EU? The case study of green industries
Provedor de dados: 21
Autores: Svendsen, Gert Tinggaard.
How should we evaluate and regulate the impacts of lobbying in the European Union (EU)? The current lack of transparency around lobbying activities and the absence of formal regulation mean that a hidden lobbying problem may prevail. The tentative case study of green industries in the EU is illustrative. The wind turbine industry, for example, benefits from ambitious environmental target levels for greenhouse gas reductions that will increase the future market for renewable energy. In contrast, for example, no environmental target levels exist that increase the future market shares of organic farming. Rational choice theory suggests that lobbying and group size advantages can explain the observed difference in achieving environmental target levels. The EU...

Autores: Uusi-Kämppä, Jaana.
The raising of cattle outdoors in winter is becoming more common in temperate areas, although there is little information available on the effects of this practice on forested environments. In this study, the concentrations of ammonium acetate extractable phosphorus (P AAAc )and mineral nitrogen (NH 4-N and NO 3-N) in soil and the quality of percolation water from an open feedlot were studied in eastern Finland in 1997–2000. In each of four pens (975–1300 m2) eight suckler cows were fed in winter from 1995 in the case of the first two pens and from 1996 in the remaining two. The suckler cows usually stayed in the front part of the feedlot. Therefore the nutrient loading was also the highest in this part of the lot. When the pens had been used for 1–2...

Price premium of organic salmon in Danish retail sale
Provedor de dados: 21
Autores: Ankamah-Yeboah, Isaac; Nielsen, Max; Nielsen, Rasmus.
The year 2016 will be pivotal for organic aquaculture producers in EU, because it represents the deadline for  implementing the complete organic life cycle in aquaculture production. Depending on the sturdiness of farms  already producing, such a shift in the industry may affect production costs of exclusively using organic fry for  production. If the profitability of the primary organic aquaculture producers should be maintained, then farmers  must be able to correspondingly receive higher prices, transmitted through the value chain from the retail  market. This study identifies the price premium for organic salmon in Danish retail sale using consumer panel  scanner data from households by applying a random effect hedonic price model that permits...

Fresh and residual phosphorus uptake by ryegrass from soils with different fertilization histories
Provedor de dados: 21
Autores: Oberson, Astrid; Tagmann, Hans U.; Langmeier, Monika; Dubois, David; Mäder, Paul; Frossard, Emmanuel.
Organic farming largely depends on animal manure as a source of phosphorus (P) and the recycling of animal manure globally is becoming increasingly important. In a pot experiment, using radioactive P labeling techniques, we studied ryegrass uptake of P applied with animal manure and water soluble mineral fertilizer to soils that had been cropped for 22 years according to organic or conventional farming practices. The soils differed in P status and microbial activity. Labeling soil-available P also allowed assessing the uptake from residual P that remained in the soils because of their different fertilization histories. On each soil, recovery of fresh manure P in four harvests of ryegrass shoots was lower than recovery of mineral P. It ranged from 24% to...

Why have basic principles for organic agriculture? … and what kind of principles should they be?
Provedor de dados: 21
Autores: Alrøe, Hugo Fjelsted; Kristensen, Erik Steen.
Recently, discussions of basic principles for organic agriculture (and similar ideas) have emerged in several different settings (Benbrook &amp; Kirschenmann 1997, DARCOF 2001, Lund &amp; Röcklinsberg 2001, Verhoog &amp; al. 2003, this issue of Ecology &amp; Farming). In this article we discuss the purposes and functions of such principles and what the principles should look like in order to meet these purposes. We state that there is a need for identifying a few basic principles for organic agriculture, and that the principles must be normative, or ethical, principles on how to act in an organic way, if organic farming is to continue as a distinct alternative to mainstream agriculture. We argue that basic normative principles can help resist unwanted...

Viele wichtige Gemüseschädlinge, wie zum Beispiel die Möhrenfliege, die Kleine Kohlfliege und die Kohldrehherzgallmücke, sind ausgesprochene Tiefflieger, das heisst sie bewegen sich in oder nur knapp über der Vegetation fort. Mit vertikal stehenden Netzen, so genannten Insektenzäunen, können diese Schädlinge am Einflug in die Kultur gehindert werden.   Als wichtigste Schlussfolgerung aus den Versuchen in den Jahren 2002 und 2003 lässt sich sagen, dass die Insektenzäune gegenüber den bekannten Kulturschutznetzen entscheidende Vorteile bieten: (1) Kein Aufliegen der Netze auf der Kultur.

Soil phosphorus (P) fertility management in organic cropping systems is a debated issue in the general context of decreasing resources in a near future. A survey showed that in Midi-Pyrenees a majority of stockless organic cropping systems present overdrawn P balances. We investigated the impacts of P balances on the soil plant available P and nutrition status on the long-term field experiment of La Hourre (CREAB, Auch, France), which is representative of rainfed systems set on clayey calcareous soils. The changes in soil plant available P were monitored between 2002 and 2012 using P Olsen soil test. The results specified the declining rate of P availability in time and according to the amplitude of the negative balance. The levels of soil available P did...

Extrato de alho melhora a superação da dormência de videiras ‘Niagara Rosada’em regiões subtropicais.
Provedor de dados: 21
Autores: Botelho, Renato Vasconcelos; Pires, Erasmo José Paioli; Moura, Mara Fernandes; Terra, Maurilo Monteiro; Tecchio, Marco Antonio.
Nas regiões com invernos amenos, normalmente as exigências de frio para a quebra de dormência de gemas de videiras não são atendidas, e apenas os produtos altamente tóxicos CaCN2 e H2CN2 são recomendados na viticultura convencional para quebra de dormência. A proposta deste estudo foi verificar o efeito do extrato de alho na quebra de dormência de videiras ‘Niagara Rosada’, em dois diferentes vinhedos. A dose mais elevada de extrato de alho (70mL L-1)demonstrou ter um grande potencial para a quebra de dormência na produção orgânica, apresentando efeitos similares aos das cianamidas, na quebra de dormência. Este tratamento aumentou a porcentagem de brotação e o número de cachos, antecipou o começo da brotação e reduziu o ciclo entre poda e colheita.

The transfer of knowledge and information gained from scientific investigations into farm practice is a primary constituent of applied agricultural science. The importance of this for both agricultural practice and agricultural science is in stark contrast with the fact that only very few studies have been conducted so far which have focussed on the framework required to achieve a successful transfer of knowledge.   Both the necessary prerequisites for and potential barriers to the successful transfer of knowledge regarding the issue of animal health have been the topic of this study taking different stakeholder perspectives into account.

Impact of year of harvest, genotype and  cultivation method on bioactives and Pru d 1  allergen content in plums
Provedor de dados: 21
Autores: Picchi, V; Lo Scalzo, Roberto; Kurze, E.; Fibiani, M; Vangdal, Eivind; Schwab, Wilfried.
The present work studied the effect of the year of harvest, the genotype and the cultivation  method on the nutritional quality and the allergen content of three plum cultivars. The common  quality parameters and the phytochemical content strongly varied with the year and the cultivar,  while the system of cultivation had a minor influence. In particular, ascorbic acid greatly  decreased in 2016 compared to 2015, while polyphenols were higher in 2016. The health-promoting  compounds, and particularly phenolics, were significantly correlated with the antioxidant  capacity. Finally, the allergen content was strongly dependent on the content of flavan-3-ols,  suggesting that this class of phenolics is determinant in influencing the allergen content in  plums....

Autores: Mäder, Paul; Fliessbach, Andreas; Dubois, David; Gunst, Lucie; Fried, Padruot; Niggli, Urs.
An understanding of agroecosystems is a key to determining effective farming systems. Here we report results from a 21-year study of agronomic and ecological performance of biodynamic, bioorganic, and conventional farming systems in Central Europe. We found crop yields to be 20% lower in the organic systems, although input of fertilizer and energy was reduced by 34 to 53% and pesticide input by 97%. Enhanced soil fertility and higher biodiversity found in organic plots may render these systems less dependent on external inputs.

Ecology of the ochratoxin A producing Penicillium verrucosum: Occurrence in field soil and grain with special attention to farming system and on-farm drying practices
Provedor de dados: 21
Autores: Elmholt, Susanne.
Mycotoxin contamination of organically grown cereals has been a growing concern during recent years, one of the most important being ochratoxin A (OTA). In countries with a temperate, humid climate, OTA is produced by Penicillium verrucosum and it is crucial to focus on the fungus to obviate problems. This paper presents results to elucidate different aspects of the ecology of P. verrucosum. In a survey of differently farmed soils, P. verrucosum was found in 11 out of  65 soils (35% of the organically and 7% of the conventionally cultivated), these being the first reports of its natural occurrence in soil. Except for two soils it was found with low frequencies (100-300 cfu g dry soil-1), and the results point to home grown seed as a potential risk of soil...

Assessing Risk Factors in the Organic Control System: Evidence from Inspection Data in Italy
Provedor de dados: 21
Autores: Zanoli, Raffaele; Gambelli, Danilo; Solfanelli, Francesco.
Certification is an essential feature in organic farming, and it is based on inspections to verify compliance with respect to European Council Regulation—EC Reg. No 834/2007. A risk based approach to noncompliance that alerts the control bodies to activate planning inspections would contribute to a more efficient and cost-effective certification system. An analysis of factors that can affect the probability of noncompliance in organic farming has thus been developed. This article examines the application of zero-inflated count data models to farmlevel panel data from inspection results and sanctions obtained from the Ethical and Environmental Certification Institute, one of the main control bodies in Italy. We tested many a priori hypotheses related to the...

Autores: Pinna, Massimo; Spagnolo, Sandra; Gamba, Ursula.
Brassica juncea è una pianta annuale appartenente alla famiglia delle Cruciferae, usata nelle nostre aree come coltura da sovescio, sia per aumentare la sostanza organica, che per la biofumigazione del terreno. Ci sono alcuni sistemi di protezione naturali, basati sulla produzione di molecole con attività biologica contro fitopatie e fitofagi. Nella famiglia Brassicaceae esiste il sistema chimico Glucosinolati (GLS) - Mirosinasi il quale è capace di generare composti tossici per funghi patogeni e nematodi. Durante il 2003 e il 2004, il C.R.A.B. ha testato le opportunità d'uso di Brassica juncea come biofumigante. L'azione degli isotiocianati presenti in B. juncea risulta funzionare anche contro i semi delle infestanti presenti nel terreno. Negli ultimi...

An alternative substrate in the biogas or bioethanol production may be the sugar containing juice obtained after fractionation of beets into a juice used for fermentation and into a pulp used for feeding. The objective of the present experiment was to evaluate the fresh pulp of top and root from sugar (Angus) and fodder (Colosse) beets as feed for pigs and ruminants. The pulp was prepared by a cold mechanical pressing. Two digestibility experiments were carried out according to the difference method. In experiment 1, 30 sows were housed individually in metabolic cages for 12 d, and urine and feces were collected during the last 7 d. The daily ration consisted of either root or top pulp combined with a basal diet. In experiment 2, 25 wethers were housed...

Meeting the growing demand for animal-sourced food, prompted by population growth and increases in average per-capita income in low-income countries, is a major challenge. Yet, it also presents significant potential for agricultural growth, economic development, and reduction of poverty in rural areas. The main constraints to livestock producers taking advantage of growing markets include; lack of forage and feed gaps, communal land tenure, limited access to land and water resources, weak institutions, poor infrastructure and environmental degradation. To improve rural livelihood and food security in smallholder crop-livestock farming systems, concurrent work is required to address issues regarding efficiency of production, risk within systems and...

Ökologische Milchziegenhaltung - Jahr für Jahr mehr Milch -
Provedor de dados: 21
Autores: Rahmann, Gerold; Hauschild, Birte.
Der Bio-Ziegenmilchmarkt boomt und die Preise sind interessant (&gt;0,70 €/kg). Ziegenmilchproduktion benötigt keine Milchquote und sie kann auf relativ wenig Fläche und mit vergleichsweise einfachen Gebäuden und wenig Kapital als Haupterwerbszweig aufgebaut werden. Außerdem sind Ziegen tolle Tiere. Immer mehr Betriebe überlegen deswegen den Einstieg in die Produktion. Es gibt jedoch nur wenig Erfahrung mit dem Aufbau einer Bio-Milchziegenherde. Unklar ist vor allem, welche Leistungen zu erwarten sind. Am Institut für Ökologischen Landbau der FAL in Trenthorst wurde 2001 mit Lämmern eine Milchziegenherde etabliert, die seit 2003 gemolken wird. Neben den üblichen Forschungsarbeiten mit dieser Herde (Eutergesundheit, Milchqualität, Parasitenkontrolle,...

Although pigs are commonly infected with Cryptosporidium and Giardia duodenalis, and thus potential reservoirs of zoonotic species (or genotypes), little is known about age-related infection levels, seasonal differences and genetic variation in naturally infected pigs. Thus, to characterise seasonal and age-related variation in prevalence and intensity of infections at farm level, (oo)cyst shedding was monitored at quarterly intervals (September 2011 to June 2012) in piglets (n=152), young pigs (n=234), finishers (n=230) and sows (n=240) from three organic, Danish farms. (Oo)cysts were quantified by immunofluorescence microscopy; and representative Cryptosporidium (n=75) and Giardia (n=67) positive subsamples were characterized by amplification and partial...

Subsoil loosening eliminated plough pan but had variable effect on crop yield
Provedor de dados: 21
Autores: Munkholm, Lars J.; Olesen, Jørgen E.
Subsoil compaction is a widespread problem on Danish arable soils and especially in form of plough pan compaction. Subsoil compaction may reduce crop yield and quality, increase negative environmental impact (e.g. in form of increased nitrogen leaching), and reduce soil workability and traffic ability of the soil. Danish Institute of Agricultural Sciences has in a DARCOF project investigated the effect of subsoil loosening. The investigations were carried out in an organic crop rotation experiment at two sandy loams: Flakkebjerg (13% clay) and Foulum (8% clay).

Organic Farming as a Commons for Protecting Water Resources / L’agriculture biologique comme bien commun pour protéger la ressource en eau
Provedor de dados: 21
Autores: Allain, Sophie.
Today, organic farming is also a provider of public goods, promoted by an increasing number of actors. It may be seen as a “commons”, that has to be shaped and developed by new types of collective commitments to study. Two French experiences in that perspective aiming to protect water resources and led by local authorities have been analyzed. The study shows that the local authority behaves as a facilitator of territorial development plan. It acts through two complementary levers, the control of supply (land and ownership) and demand (institutional catering). Whereas environmental efficiency remains to be proved, the projects rely on an increasing collective mobilization and develop according to their ability for budding and territorial rooting. New modes...

Fatty acid composition, fat-soluble vitamin concentrations and oxidative stability in bovine milk produced on two pastures with different botanical composition
Provedor de dados: 21
Autores: Adler, Steffen A.; Dahl, A.V.; Jensen, S.K.; Thuen, E.; Gustavsson, A.-M.; Steinshamn, H.
Previous research has shown that grazing pastures compared to feeding preserved forages has large impact on milk fatty acid (FA) composition, but differences between grazing red clover (Trifolium pratense L.) or white clover (Trifolium repens L.) are small, whereas the herbage proportions of dicotyledon botanical families is positively correlated with the milk-fat proportions of total polyunsaturated FA when grazing pastures in the Alps.

Reduced tillage is increasingly promoted to improve sustainability and productivity of agricultural systems. Nonetheless, adoption of reduced tillage by organic farmers has been slow due to concerns about nutrient supply, soil structure, and weeds that may limit yields. Here, we compiled the results from both published and unpublished research comparing deep or shallow inversion tillage, with various categories of reduced tillage under organic management. Shallow refers to less than 25 cm. We found that (1) division of reduced tillage practices into different classes with varying degrees of intensity allowed us to assess the trade-offs between reductions in tillage intensity, crop yields, weed incidence, and soil C stocks. (2) Reducing tillage intensity in...

Este produto tem sido largamente utilizado com sucesso por agricultores orgânicos e convencionais em todo o estado do Rio de Janeiro, no controle de várias enfermidades vegetais em diferentes culturas. Em bioensaios realizados em casa de vegetação, observou-se uma ação bacteriostática equivalente a de produtos químicos comerciais contra Xanthomonas campestris pv. vesicatoria em mudas de pimentão (Capsicum annuum L.), numa concentração de 5%. Nos bioensaios in vitro, onde foram testadas as concentrações de 2, 5 10 e 50% do Agrobio comercial,...

Late blight of potatoes, caused by Phytophthora infestans, is particularly difficult to prevent or control in organic agriculture. In this study, the host resistance of selected varieties to foliar and tuber blight and their yield under organic growing conditions were assessed in trials carried out in four countries (Switzerland, France, England and Norway) in 2001 and 2002. The objective was to identify new, more resistant varieties which might replace some of the more susceptible varieties which are currently grown in organic agriculture. In each country, five test varieties were compared with two reference varieties, identical for all sites, and with two locally popular varieties. In addition, the effect of copper fungicides was assessed for all...

Autores: Bosshard, C.; Frossard, E.; Dubois, D.; Mäder, P.; Manolov, I.; Oberson, A.
Physically separated soil organic matter (SOM) fractions may take different functions in soil N dynamics. We studied the effect of long-term organic matter (OM) management and different soil biological activity on the incorporation of N added with organic and mineral amendments into aggregate fractions and size density fractions. We applied 15N-labeled sheep feces, urine, and mineral fertilizer to microplots installed in plots of conventional (CONMIN) and bio-organic (BIOORG) cropping systems. Soil sampled 112 d after amendment was separated into macro-, microaggregates, and microstructures. Aggregates were then fractionated into free light fraction (LF), intra-aggregate particulate organic matter (iPOM),and the mineral-associated organic matter fraction...

Improvement of biological control by volatile plant compounds
Provedor de dados: 21
Autores: Holopainen, Jarmo K.
Compared to conventional farming the pest management strategies in organic farming is based on better plant resistance and sustainable cultivation technique that does not destroy the natural enemies of pest insects. Methods that reduce feeding efforts of pests and maintain strong population of predators and parasitoid on crop plant, are the way forward for sustainable plant protection strategies. Volatile compounds extracted from plants and sprayed on crop plants are one of the key factors for the development of these techniques.

A variety of products incorporating single aspects of organic production systems such as lower inputs of pesticides, food additives or concentrated animal feed is found on the food market (referred to as low-input products hereafter). In our study, we analysed how consumers react to low-input products in a purchase simulation with certified organic, conventional and low-input products. In the purchase simulations, each participant was asked to make three consecutive purchase decisions, one each for milk, yogurt and apples. The results of a cluster analysis revealed one cluster with a high preference for organic products and three clusters that featured considerable shares of low-input purchases. The latter clusters, however, were not characterised by a...

The Critical Point of Conventionally Bred Soft Wheat Varieties in Organic Farming Systems
Provedor de dados: 21
Autores: Konvalina, Petr; Stehno, Zdenek; Moudry, Jan.
Nowdays, wheat is the most important crop for organic farming system. However, the varieties breeded and tested in the conditions of organic farming system are still missing. It gives rise to very low level of yield in the Czech Republic (less than 50% of level of convention  one in the same conditions). One of the reasons is that the ideotype of organic breeded variety is different from conventional one. The varieties suitable for organic farming system differ in many respects from those adopted in conventional farming. The first difference is obvious from the conventional tests of use value of the varieties, taking just some direct indicators influencing the main parameter (yield) into account. Generally speaking, the features to be tested can be divided...

Neem-Azal T/S to control leafhoppers and aphids in greenhouse sweet pepper and tomato.
Provedor de dados: 21
Autores: Daniel, Claudia; Koller, Martin; Wyss, Eric.
Aphids and leafhoppers can cause heavy damage to sweet pepper (Capsicum annuum) and tomato (Solanum lycopersicum). Neem-Azal T/S was therefore evaluated in greenhouse experiments for leafhopper and aphid control.   In 2005, five organic greenhouse compartments were treated with Neem-Azal T/S (0.2%, 1000-1500 L water ha-1; two treatments on tomato; three treatments on sweet pepper) for control of leafhoppers; four greenhouse compartments were left as untreated controls. Leafhopper flight activity was monitored using yellow sticky traps. Leaf damage was estimated by evaluating the fifth leaf from the top of the plant on 100 plants per plot. Flight activity was reduced by 80% (Abbott’s formula; 11-20 days after the 2nd treatment) to 93% (60-75 days after last...

This study aimed to investigate the ideal brood area to be introduced for strengthening Apis mellifera colonies, considering variations in the hive's internal ambience. Therefore, eight colonies were equipped with data loggers for recording variations in temperature and humidity inside the hives. Then, these colonies were split in four treatments involving the swapping of four, three, two and one brood comb between strong and weak colonies. Growth in the amount of brood and food stores to the four colony strengthening treatments was assessed counting the comb cells to record changes in the brood and food area. The colonies tended to restore their normal thermoregulation within four hours after they had been manipulated and the hive cover had been closed,...

Autores: Levin, Gregor.
This article presents an investigation of relationships between organic farming and landscape composition in Denmark. Landscape composition was analysed in terms of density of uncultivated landscape elements (I), number of land uses per hectare (II), diversity of land use (III) and mean field size (IV). Two analytical approaches were used. The first was based on an examination of the national agricultural registers for 1998, 2001 and 2004. The second approach used aerial photo interpretation for an analysis of 72 conventional and 40 organic farms within three sample areas for 1982, 1995 and 2002. The national analysis indicated that organic farming has a direct effect on landscape composition. In 2001, organic farms were characterised by a higher number of...

Natural enemies and their food sources in an organic crop rotation with undersown crops and animal manure
Provedor de dados: 21
Autores: Axelsen, Jørgen Aagaard; Toft, Søren; Lôvei, Gabor.
The abundance and species composition of natural enemies (spiders and carabid beetles) and some of their important arthropod food sources (microarthropods, dipterans and hymenopterans) were sampled by soil extraction, pitfall traps and sticky traps in winter wheat placed in an organic crop with undersown catch crops and animal manure (slurry). The working hypothesis was that the undersown crops and animal manure would stimulate the microarthropods and other food sources, thereby enhancing the abundance of natural enemies.    The ANOVA analyses revealed no impact of manuring and undersown catch crops on the microarthropods, but there was a larger abundance of most predator groups in the manured plots. There was not found any impact of undersown crops on the...

Environmental and economic indicators are calculated at crop rotation scale to complete the previous yield assessment. In 2012, a research program enabled the model adaptation to organic systems, taking into account weed management and organic inputs supply. This program also allowed to parameterize the web software in the Ile-de-France region for 8 soil types and 18crops. Parameterization has been validated for the most common situations. Validation remains to be done for less common ones. When completed, validation will make it possible to test the software in promising situations of...

Competitive ability of Rumex obtusifolius against native grassland species: above- and belowground allocation of biomass and nutrients
Provedor de dados: 21
Autores: Zaller, Johann G.
Understanding the competitive ability of Rumex obtusifolius against grassland species is essential for developing efficient control strategies against docks. Here we present results from a greenhouse experiment where we tested shoot and root competition between Rumex regenerating from rhizome fragments and grassland species (grasses, herbaceous and leguminous species). Competitive ability was expressed as the relative above- and belowground biomass partitioning and, concentrations and allocation of carbon and nitrogen of the plant species studied. Regeneration of Rumex was significantly affected by  competition through neighbouring native grassland species. Rumex responded to concurrent shoot and root competition of grassland species with 50% more...

Fatty acid and fat-soluble antioxidant concentrations in milk from high- and low-input conventional and organic systems: seasonal variation
Provedor de dados: 21
Autores: Butler, Gillian; Nielsen, Jacob H.; Slots, Tina; Seal, Chris; Eyre, Mick D.; Sanderson, Roy; Leifert, Carlo.
BACKGROUND: Previous studies showed differences in fatty acid (FA) and antioxidant profiles between organic and conventional milk. However, they did not (a) investigate seasonal differences, (b) include non-organic, lowinput systems or (c) compare individual carotenoids, stereoisomers of α-tocopherol or isomers of conjugated linoleic acid. This survey-based study compares milk from three production systems: (i) high-input, conventional (10 farms); (ii) low-input, organic (10 farms); and (iii) low-input non-organic (5 farms). Samples were taken during the outdoor grazing (78 samples) and indoor periods (31 samples).  RESULTS: During the outdoor grazing period, on average, milk from the low-input systems had lower saturated FAs, but higher mono- and...

Forschung an Nutztieren basiert heute weitgehend auf der geistigen Grundhaltung, in Zucht, Haltung, Fütterung und Pflege den maximalen Grad von ausschliesslich ökonomisch orientierter Gestaltung ihrer Innen- und Umwelt herauszuarbeiten. Die Limitierung dieses Vorgehens besteht nur darin, die Grenze zur offensichtlichen Schädigung der Tiere nicht zu überschreiten. Ziel ist also eine Minimierung der Erfüllung legitimer artgemässer Ansprüche unter möglichst knapper Vermeidung daraus resultierender Krankheiten, Sterilitäten, vorzeitiger Abgänge und Leistungseinbussen. Diese Gratwanderung von Symptomfreiheit an der Grenze der Belastungsfähigkeit hat man sich angewöhnt, als Gesundheit misszuverstehen.    Tiermedizinische Forschung wiederum hat weitgehend nur zum...

What Motivates Czech Consumers to Buy Organic Food?
Provedor de dados: 21
Autores: Urban, Jan; Zverinova, Iva; Scasny, Milan.
The objective of this paper is twofold. First, the authors aim to analyse the factors that affect the intention of Czech consumers to purchase organic food using the theory of planned behaviour (TPB). Second, they employ an extended TPB model that introduces descriptive norms as an additional factor of behavioural intention. This study exploits data from a consumer survey of a sample of the Czech general adult population (N = 252) conducted in 2010. Structural equation modelling with an ML estimator is used to estimate model parameters. The empirical model derived from the TPB explains 44% of the variability of intention to purchase organic food. Descriptive norms are empirically distinct from injunctive norms and their inclusion in the model increases the...

Autores: Swer, H; Dkhar, MS; Kayang, H.
The effect of different organic fertilisers (farm yard manure [FYM]; vermicompost [VC]; plant compost [PC] and integrated compost [INT], i.e. a combination of FYM, VC and PC in a 1:1:1 ratio) on the population and diversity of soil fungi was investigated in a maize-French bean trial. Fungal populations were much higher in organically fertilised plots as compared to the control (CTRL) and showed a decreasing trend in the order FYM&gt;PC&gt;INT&gt;VC&gt;CTRL. Altogether, 122 fungal species and two sterile mycelia were isolated from all the plots of which 25 fungal genera belonged to Deuteromycotina, seven to Ascomycotina, four to Zygomycotina and one to Mastigomycotina. The most common genera isolated from all the plots include Penicillium, Aspergillus,...

Government intervention in green industries: Lessons from the wind turbine and the organic food industries in Denmark
Provedor de dados: 21
Autores: Daugbjerg, Carsten; Svendsen, Gert Tinggaard.
Government intervention in green infant industries may be justified as a strategy to increase the provision of public goods. How should government policies be designed to promote such industries? One way to analyse this question is to compare government intervention in green infant industries in which it has been successful with green infant industries in which it has been less successful. The Danish government has intervened intensively in the wind turbine industry and organic farming sector mainly for environmental reasons since 1992 and 1987 respectively, but with very different impacts. While the electricity market share of wind energy reached 20% in 2007, organic food consumption lags behind with a food market share of approximately 8.5% in 2007. This...

Effect of foliar application of selenium on its uptake and  speciation in carrot
Provedor de dados: 21
Autores: Kapolna, Emese; Hillestrøm, Peter; Laursen, Kristian; Husted, Søren; Larsen, Erik H.
Carrot (Daucus carota) shoots were enriched by selenium  using foliar application. Solutions of sodium selenite   or sodium selenate at 10 and 100 lg Se ml�1, were sprayed on the carrot leaves and the selenium content and uptake rate of selenium were estimated by ICP–MS analysis. Anion  and cation exchange HPLC were tailored to and applied for the separation of selenium species in proteolytic extracts  of the biological tissues using detection by ICP–MS or ESI–MS/MS. Foliar application of solutions of selenite or selenate at 100 lg Se ml�1 resulted in a selenium concentration of up to 2 lg Se g�1 (dry mass) in the carrot root whereas the selenium concentration in the  controls was below the limit of detection at 0.045 lg Se g�1 (dry mass)....

The possibility of improving resistance in pea against the root pathogen Aphanomyces euteiches using composite cross as a breeding and selection method was examined. In order to maintain acceptable agricultural features and high yield 6 out of the 8 parental varieties in the present composite-cross were commercially grown varieties. Populations of the composite cross were grown up to five generations with selection pressure in soil heavily infested with pea root pathogens or without selection pressure on soil free of pea root pathogens. Yield of populations of the F9 and F10 generations of the composite cross grown with selection pressure was on average 35% higher than that of the population obtained without selection pressure as well as the average yield...

Dependency of organic farms on direct payments in selected EU member states: today and tomorrow
Provedor de dados: 21
Autores: Offermann, Frank; Nieberg, Hiltrud; Zander, Katrin.
This paper examines the development of the role of government support in the financial situation of organic farms in selected Western and Eastern European countries, contrasting dependency on direct payments with that of conventional farms and assessing the impact of foreseeable changes in the political and economic environment. The results show that direct payments play an important role in the financial viability of organic farms in both Western and Eastern European countries. The level of specific support for organic farming is put into perspective, as other support payments and market returns contribute larger shares to total farm revenue in all the countries analysed. Modelling analyses show that support payments will continue to play an important...

Autores: Lanza, M.; Scerra, M.; Bognanno, M.; Buccioni, A.; Cilione, C.; Biondi, L.; Priolo, A.; Luciano, G.
In the present study, we have hypothesized that replacing barley with high proportions of dried citrus pulp in a concentrate-based diet for lambs could increase the intake of unsaturated fatty acids and could reduce the rate of the ruminal biohydrogenation of PUFA, with a consequent improvement of the intramuscular fatty acid composition. To test this hypothesis, 26 Comisana lambs were divided into 3 groups and for 56 d were fed a barley-based concentrate diet (CON; 8 lambs) or 2 diets in which barley was replaced with 24% (CIT24; 9 lambs) or 35% (CIT35; 9 lambs) dried citrus pulp. An overall improvement of the fatty acid composition of LM from lambs fed citrus pulp-containing diets was found. The PUFA/SFA ratio was lower (P &lt; 0.05) in the LM from lambs...

Opportunity costs for maize associated with localised application of sewage sludge derived fertilisers, as indicated by early root and phosphorus uptake responses
Provedor de dados: 21
Autores: Lemming, Camilla; Oberson, Astrid; Hund, Andreas; Jensen, Lars Stoumann; Magid, Jakob.
Background: Phosphorus recycling from waste and localised placement of fertilisers can potentially improve sustainable P management in agriculture. However, knowledge about root and plant P uptake responses to placement of complex waste-derived fertilisers is lacking.   Methods: Sewage sludge (SS) and sewage sludge ash (ASH) were tested against triple superphosphate (TSP) in a rhizobox setup where maize shoot and root growth and architecture were followed for 30 days. The three P sources were either mixed homogenously into the soil (slightly acidic, low in available P and moderate P fixing capacity; labelled with 33P) or localised in a patch close to the seed.  Results: Localisation of TSP and SS both induced increased root length density in and around the...

Moving on – European organic farming movements between political action and self-reflection
Provedor de dados: 21
Autores: Moschitz, Heidrun.
Organic farming movements in Europe are widely recognised as a positive force by market actors and civil society, as well as relevant actors in policy networks. At the same time, the organic movement is in a process of self-reflection, reconsidering its value basis. Taking account of both a policy network and a social movement perspective, this article seeks to understand political action of the organic sector. Making use of a cross-country comparison of European organic farming policy networks, it conceptualises the consequences of such action with regard to political influence and the identity of the organic farming movement. While different strategies are employed to influence politics, a space needs to be opened up within the movements for continuous...

Combining physical, cultural and biological methods: prospects for integrated non-chemical weed management strategies
Provedor de dados: 21
Autores: Hatcher, Lecturer Paul; Melander, Senior scientist Bo.
Physical, cultural and biological methods for weed control have developed largely independently and are often concerned with weed control in different systems: physical and cultural control in annual crops and biocontrol in extensive grasslands.  We discuss the strengths and limitations of four physical and cultural methods for weed control: mechanical, thermal, cutting, and intercropping, and the advantages and disadvantages of combining biological control with them.  These physical and cultural control methods may increase soil nitrogen levels and alter microclimate at soil level; this may be of benefit to biocontrol agents, although physical disturbance to the soil and plant damage may be detrimental.  Some weeds escape control by these methods; we...

Provedor de dados: 21
Autores: Stein-Bachinger, Karin; Reckling, Moritz; Bachinger, Johann; Hufnagel, Johannes; Wijnand, Koker; Granstedt, Artur.
Eutrophication caused by agriculture is an increasing ecological threat to the Baltic Sea. Modern, resource-efficient farming systems based on integrated plant and animal production, effective nutrient recycling and low external inputs can enhance multiple agro-ecosystem  services, resulting in reduced pollution. Practical examples of such farming systems are not widespread.  Therefore, the Baltic  Ecological Recycling  Agriculture  and Society (BERAS) Implementation project aimed to foster this systemic shift. In this paper, agronomic strategies are described to improve nitrogen (N) efficiency for the conversion to ecological recycling agriculture (ERA). First, N farm gate balances of 22 farms in conversion are presented. They showed a large variation...

Auswirkungen einer Schwefeldüngung auf Ertrag und Qualität von Weizen schwefelmangelgefährdeter Standorte des Ökologischen Landbaus.
Provedor de dados: 21
Autores: Hagel, Ingo.
Durch die Reduzierung der S-Einträge in landwirtschaftliche Ökosysteme infolge der notwendigen Installierung von Rauchgasentschwefelungsanlagen kommt es nicht nur bei S-bedürftigen Kulturen wie Raps sondern auch bei Weizen zu Ertragsausfällen sowie Verschlechterungen der Backqualität. Da für die Verhältnisse des Ökologischen Landbaus keine Feldversuchsdaten zur Frage der Wirkung einer S-Düngung auf Ertrags- und Qualitätsparameter vorliegen, sollte dazu mit dieser Arbeit ein Beitrag geleistet werden.    Dazu wurden in zwei Untersuchungsjahren (1998 und 1999) auf je zwei Winterweizenschlägen (Sorten BUSSARD, RENAN und BELISAR) ökologisch wirtschaftender Betriebe in S-Mangel gefährdeten Gebieten Ost-Holsteins Schwefeldüngungsversuche angelegt. Gedüngt wurde...

Provedor de dados: 21
Autores: Linnemann, Ludger; Leithold, Günter; Rauber, Rolf.
Aktuelle Ergebnisse der letzten 10 Jahren, die den wissenschaftlichen Fortschritt für eine verbesserte Qualitätsbeschreibung von Backweizen verdeutlichen, wurden dargestellt. Ergebnisse eigener Untersuchungen zeigten, dass die Weizenqualität als SDS-Sedimentationvolumina erfaßt 1995 bei warmer, trockener Witterung während der Kornfüllung bei gleicher RP-Konzentration um etwa 65 % höher lagen. als im Jahr 1996 mit kühlem, feuchtem Witterung während der Kornfüllung. Es war nicht möglich die Qualität einer Mehlprobe allein anhand der RP-Konzentration zu beurteilen, da kein gesicherter Einfluß der Proteinmenge auf die Proteinqualität vorhanden war. Unterschiede in der Weizenqualität waren sowohl auf quantitative als auch qualitative Unterschiede in der...

Autores: Myaka, F. M.; Sakala, W. D.; Adu-Gyamfi, J. J.; Kamalongo, D.; Ngwira, A.; Odgaard, R.; Nielsen, N. E.; Høgh-Jensen, H.
Maize (Zea mays L.) is a major staple food in Sub-Saharan Africa but low soil fertility, limited resources and droughts keep yields low. Cultivation of maize intercropped with pigeonpea (Cajanus cajan L. Millsp.) is common in some areas of eastern and southern Africa. The objectives of this study were (1) to investigate dry matter, nitrogen (N) and phosphorus (P) accumulation in different plant components of maize-pigeonpea intercropping systems and (2) to report the effects of the intercrops on soil fertility. Maize-pigeonpea intercrops were compared to sole maize grown using farmers’ practices. Intercropping maize and pigeonpea increased (P&lt;0.05) total system yield compared to sole maize in terms of biomass, N and P accumulation. Pigeonpea planted in...

Moving on – European organic farming movements between political action and self-reflection
Provedor de dados: 21
Autores: Moschitz, Heidrun.
Organic farming movements in Europe are widely recognised as a positive force by market actors and civil society, as well as relevant actors in policy networks. At the same time, the organic movement is in a process of self-reflection, reconsidering its value basis. Taking account of both a policy network and a social movement perspective, this article seeks to understand political action of the organic sector. Making use of a cross-country comparison of European organic farming policy networks, it conceptualises the consequences of such action with regard to political influence and the identity of the organic farming movement. While different strategies are employed to influence politics, a space needs to be opened up within the movements for continuous...

A history of demands: philosophy and agrobiology. The significance of the founding principles of organic farming within the framework of contemporary development
Provedor de dados: 21
Autores: BESSON, Y.
Organic farming originally deals with the problematic nature/technique within a holistic view. The order of things inspires organic agronomy and social thoughts on agriculture. The link between what is and what has to be socially is not thinkable within modern right and ethic, but it is in accordance with the ancient philosophy. A. Howard, R. Steiner, H.P. Rusch, M. Fukuoka, found their biology according to this fundamental way of behaving. The biology of those founders stands between various philosophical speculations, esoteric speculations, empirical observations, and scientific approaches. According to the ancient philosophy, these authors are suggesting an imitation of nature based on a cyclic understanding. Human intrusion in nature, although founding...

Sustainable management of cultivated peatlands in Switzerland: Insights, challenges, and opportunities
Provedor de dados: 21
Autores: Ferré, Marie; Müller, Adrian; Leifeld, Jens; Bader, Cédric; Müller, Moritz; Engel, Stefanie; Wichmann, Sabine.
Major common production activities on organic soils require drainage, which results in the loss of important ecosystem services such as carbon storage. This paper provides an overview of the farming situation on organic soils in a western region of Switzerland characterized by intensive vegetable farming and therefore by high opportunity costs of adopting sustainable practices on these soils. Based on a review of the academic and grey literature and interviews with regional experts, we find that the main challenges to a change in management practices include the profitability of the current land use, the difficult economic environment of farmers, the cultural background associated with the region, and the absence of systematic data on soil properties. We...

MAPPING SOIL SPATIAL VARIABILITY AT HIGH DETAIL BY PROXIMAL SENSORS FOR A VINEYARD PLANNING
Provedor de dados: 21
Autores: Priori, S.; L'Abate, G.; Fantappiè, M.; Costantini, E.A.C.
Planning new vineyard needs accurate information about soil features and their spatial variability. The use of soil proximal sensors, coupled by few detailed soil observations and analysis allows to obtain high detailed maps of soil variability at affordable costs. The work showed the methodology to interpolate the proximal sensors data and to delineate homogeneous area by clustering, corresponding to likely soil units. The description and analysis of one profile for each homogeneous area allowed to describe the soil features of each soil typological units and to produce useful thematic maps for vineyard planning.

Farm gate nutrient balances of organic dairy farms at different intensity levels in Germany
Provedor de dados: 21
Autores: Haas, Guido; Deittert, Christine; Köpke, Ulrich.
Organic farms are characterized as low external input agro-ecosystems. Currently, some organic dairy farmers feed higher amounts of concentrates and succulent feed, some of which is purchased, to increase the dairy performance of their cows. To assess the environ¬mental impact of this practice, nutrient balances at the farm-gate level of 26 organic dairy farms located in two different regions in Germany were compiled and analysed. The farms are characterised by different production features and feeding intensity levels (0 - 2.72 t DM of concentrates per cow and year, which was 0 - 378 g kg-1 milk) yielding 5,150 - 8,790 kg milk on average per cow and year.   The area- and product- (milk) related farm-gate nutrient budgets for P and K are almost balanced...

Long-Term Management Affects the Community Composition of Arable Soil Seedbanks
Provedor de dados: 21
Autores: Rotchés-Ribalta, Roser; Armengot, Laura; Mäder, Paul; Mayer, Jochen; Sans, Francesc Xavier.
The intensification of farming practices has reduced weed infestations, but it has also led to a reduction in weed diversity and changes in species composition. These effects are well described for aboveground flora; however, it is less clear how these effects might be expressed in the soil weed seedbank. We evaluated the effects of different long-term farm management strategies on the weed seedbank abundance, diversity, and community composition in the DOK (bioDynamic, bioOrganic, and Konventionell) field trial established in 1978 at Therwil, Switzerland. The trial compares biodynamic, organic, and conventional farming systems, which mainly differ in fertilization, weed control strategies, and pest control. The species richness and seed abundance of the...

Role of benchmark technology in sustainable value analysis : an application to Finnish dairy farms
Provedor de dados: 21
Autores: Kuosmanen, Timo; Kuosmanen, Natalia.
Sustainability is a multidimensional concept that entails economic, environmental, and social aspects. The sustainable value (SV) method is one of the most promising attempts to quantify sustainability performance of firms. SV compares performance of a firm to a benchmark, which must be estimated in one way or another. This paper examines alternative parametric and nonparametric methods for estimating the benchmark technology from empirical data. Reviewed methods are applied to an empirical data of 332 Finnish dairy farms. The application reveals four interesting conclusions. First, the greater flexibility of the nonparametric methods is evident from the better empirical fit. Second, negative skewness of the regression residuals of both parametric OLS and...

Susceptibility of different life stages of the European cherry fruit fly, Rhagoletis cerasi, to entomopathogenic fungi
Provedor de dados: 21
Autores: Daniel, Claudia; Wyss, Eric.
The effects of six fungus isolates on the mortality of different life stages of the European cherry fruit fly, Rhagoletis cerasi (Diptera: Tephritidae), were assessed in a series of laboratory experiments to find an isolate suitable for biological control. In a first step, the effects of fungus treatments on mortality, mycosis and fecundity of adult flies at a concentration of 107 conidia/ml were evaluated. All fungus isolates caused mycosis but virulence varied considerably among the isolates. Beauveria bassiana and Isaria fumosorosea caused 90–100% mortality and had the strongest influence on fecundity. Metarhizium anisopliae also induced high rates of mortality, while the pathogenicity of Isaria farinosa was low. The effects of lower conidia...

Emission and production of greenhouse gases and ammonia during storage of solids separated from pig slurry: effects of covering
Provedor de dados: 21
Autores: Hansen, Martin N.; Henriksen, Kaj; Sommer, Sven G.
Separation of slurry produces a solid fraction that is stored in manure heaps before being used as a fertiliser in crop production. Considerable amounts of ammonia (NH3) and greenhouse gases may be emitted during storage, which has deleterious environmental effects. The emission levels can be expected to depend on oxygenation level inside the bulk of the stored manure and therefore on storage conditions. An experiment was thus set up to study gaseous emissions during storage of the solid fraction, and the effects of the oxygenation of manure heaps on emissions of NH3 and various greenhouse gases. Emissions of NH3 and the greenhouse gases methane (CH4), nitrous oxide (N2O), and carbon dioxide (CO2) from an uncovered and covered heap of solids separated from...

O cultivo em aléias tem sido recomendado como alternativa para a substituição da agricultura de corte e queima, no trópico úmido, devido à grande capacidade de produção de matéria orgânica e de reciclagem de nutrientes, mas algumas dúvidas quanto à sustentabilidade e à competição interespecífica são persistentes. O objetivo no trabalho foi avaliar a viabilidade da cultura do milho em um sistema de cultivo em aléias de leguminosas arbóreas. O delineamento experimental utilizado foi em blocos casualisados, com quatro repetições dos tratamentos: aléias de sombreiro (Clitoria fairchildiana), ingá (Inga edulis), guandu (Cajanus cajan) e leucena (Leucaena leucocephala) e uma testemunha sem aléias. Foram avaliadas a remobilização de carbono e nitrogênio, massa de...

compost-based nursery substrates: effect of peat substitution on organic melon seedlings
Provedor de dados: 21
Autores: Tittarelli, Fabio; Rea, E.; Verrastro, V.; Pascual, J.A.; Canali, S.; Ceglie, F.G.; Trinchera, A.; Rivera, C.M.
A bovine manure compost (BMC) and a green compost (GC) were evaluated as components of substrates in partial substitution of peat for organic melon seedlings production. Treatments, differentiated on the basis of the volume percentage of the two analysed composts, were compared to the control (a mixture of peat, coconut fibre and perlite). In order to respect the guidelines of organic production, all the treatments were fertilised, at the beginning of the trial, with guano. Compost-based substrates were analysed for physical, physicochemical and chemical parameters (bulk density, porosity, pH, EC, nutrients content etc.). Even though significant differences were observed, recorded values were in the range of acceptability for growing media. In terms of...

Autores: Alföldi, Thomas; Notz, Christophe.
Im Projekt «Feed no Food», oder auf Deutsch «Verfüttere keine Lebensmittel», konnte das FiBL zeigen,dass eine standortangepasste Milchproduktion ohne oder nur mit sehr wenig Kraftfutter möglich ist. Trotz bereits tiefem Kraftfuttereinsatz konnten die 69 beteiligten Biobetriebe rund einen Viertel des Kraftfutters einsparen. Würden alle Schweizer Milchviehbetriebe ihren Kraftfutterverbrauch um einen Viertel verringern, könnten rein kalorienmässig eine halbe Million Menschen ernährt werden. Projektleiter Christophe Notz zieht Bilanz.

Autores: Döring, Thomas F.; Heimbach, Udo; Thieme, Thomas; Saucke, Helmut.
Aphids are important pests in potatoes, mainly due to their ability to transmit virus diseases. 17 field experiments were conducted over 4 years at 4 sites on organically managed farms to investigate the effect of straw mulch, applied at various amounts (2–8 t ha-1) shortly after crop emergence, on aphid infestation of potato leaves. The percentage of leaves infested with aphids was repeatedly determined during the growing period in 10 experiments. It was significantly reduced in the mulched treatments at the time around 2 weeks after mulching in 4 experiments, and later, at peak infestation, in 8 experiments. The aphid population size was regularly determined in 11 experiments and was significantly reduced by mulching in 4 of them. In a small scale...

Fluorescence-based concept of Naturalness applied to organic processed fruit and vegetables
Provedor de dados: 21
Autores: Bardeau, F.; Rizkallah, J.; Acharid, A.; Sivault, S.; Neugnot, B.; Kahl, J.; Birlouez, E.; Birlouez, I.
Background: According to the European regulation N°834/2007, processing of organic food should preserve the essential qualities of the fresh raw material. Thus, assessment of processed food quality should include verification of the absence of additives and contaminants and preservation of the sensorial, nutritional and health values of the raw material. In this paper, a quantifiable concept of naturalness measuring global quality loss due to processing and storage of raw organic material is proposed. This indicator is based on Front face fluorescence; a global and sensitive technique able to assess in real time and non-destructively these various dimensions of the food quality.    Results: A strong relationship between the naturalness levels estimated...

A Postcard from Stuttgart: Rudolf Steiner's 150th anniversary exhibition 'Kosmos'
Provedor de dados: 21
Autores: Paull, John.
It is easy to imagine that Rudolf Steiner (1861­‐1925) would be delighted with the new exhibition 'Kosmos Rudolf Steiner' at Stuttgart's modernistic Kunstmuseum. Kosmos is a major retrospective exhibition of Steiner's life and ideas. Kosmos appears 150 years after Steiner's birth, and this is a timely anniversary to present the manand his ideas, fresh to a new audience. Kosmos Rudolf Steiner is, first and foremost, a celebration of a life lived with intensity, purpose and zest. Visitors may be drawn by curiosity, and others will be drawn by familiarity. Whether it was art, agriculture, architecture or anthroposophy, whether education or eurythmy, furniture or well-­‐being, Steiner touched it, and his touch has endured. After Stuttgart, the exhibition moves...

During 2003 and 2005, plant growth promoting effects of two Bacillus strains OSU-142 (N2-fixing) and M3 (N2-fixing and phosphate  solubilizing) were tested alone or in combinations on organically grown primocane fruiting raspberry (cv. Heritage) plants in terms of yield,  growth, nutrient composition of leaves and variation of soil nutrient element composition in the province of Erzurum, Turkey. The results showed  that Bacillus M3 treatment stimulated plant growth and resulted in significant yield increase. Inoculation of raspberry plant roots and rhizosphere  with M3 and/or OSU-142 + M3, significantly increased yield (33.9% and 74.9%), cane length (13.6% and 15.0%), number of cluster per cane  (25.4% and 28.7%) and number of berries per cane (25.1% and...

Soil structure, organic matter and earthworm activity in a comparison of cropping systems with contrasting tillage, rotations, fertilizer levels and manure use
Provedor de dados: 21
Autores: Riley, Hugh; Pommeresche, Reidun; Eltun, Ragnar; Hansen, Sissel; Korsaeth, Audunk.
Abstract  In order to assess long-term effects on productivity, environmental impacts and soil fertility of contrasting farming practices, six cropping systems, ranging from conventional arable without livestock to organic mixed dairy farming with few arable crops, have been compared since 1989 on a loam soil.     A decline in soil structure quality was found in a conventional arable system with annual ploughing with no rotational grass. This system had higher bulk density and mean aggregate size than other systems, and lower levels of plant available water and aggregate stability. Opposite trends were related to the proportion of grass leys in the other systems and to their levels of soil organic matter. The latter declined markedly over 15 years in the...

Effects of conventionally bred and Bacillus thuringiensis (Bt) maize varieties on soil microbial biomass and activity
Provedor de dados: 21
Autores: Fließbach, Andreas; Messmer, Monika; Nietlispach, Bruno; Infante, Valentina; Mäder, Paul.
Genetically modified (GM) maize containing genes from the soil bacterium Bacillus thuringiensis (Bt) was cultivated on 29% of the total maize production area worldwide in 2009. Most studies to date compare Bt- maize varieties with their near isogenic lines; however, there is little information on the variability of conventional maize breeding lines and how the effects of Bt varieties are ranked within. In our study on the potential risks of Bt- maize varieties, we analyzed tissue quality and compared the effects of ten conventional and GM maize varieties on soil microbiological properties in a replicated climate chamber experiment. All maize varieties were cultivated twice in the same soil microcosm. Shoot yields and soluble C in leaf tissue of Bt...

Underlying reasons of the controversy over adverse effects of Bt toxins on lady beetle and lacewing larvae
Provedor de dados: 21
Autores: Hilbeck, Angelika; Meier, Matthias; Trtikova, Miluse.
We outline important underlying reasons that fuel the decades-long controversy over adverse effects of Bt toxins expressed in genetically modified plants on beneficial, nontarget organisms. Inconsistent evaluation standards and asymmetrical levels of scrutiny applied to studies reporting significant adverse effects compared to those finding no adverse effects are described using the examples of the green lacewing (Chrysoperla carnea) and the twospotted lady beetle (Adalia bipunctata). Additionally, the chosen style and concerted nature of the rather confrontational counter study and responses in the lady beetle cases bear striking similarities to other reported examples in the field of biosafety/risk science of genetically modified plants and to other...

Ecology of the entomopathogenic fungi Beauveria bassiana and Metarhizium anisopliae in temperate agroecosystems: potential for conservation biological control
Provedor de dados: 21
Autores: Meyling, Nicolai V.; Eilenberg, Jørgen.
It is increasingly recognized that the biodiversity in agroecosystems deliver significant ecosystem services to agricultural production such as biological control of pests. Entomopathogenic fungi, specifically the anamorphic taxa Beauveria bassiana and Metarhizium anisopliae, Hypocreales (Ascomycota), are among the natural enemies of pests in agroecosystems and the fungi are candidates for future conservation biological control in temperate regions. Conservation biological control is a biological control strategy in which farming practices and environmental manipulations are adopted to enhance the living conditions for specific natural enemies of pests. However, in order to manipulate the environment for the benefit of populations of the entomopathogens,...

Currently, there is little knowledge of the establishment of repeatedly applied biological control agents (BCAs) in the phyllosphere of plants and, in particular, their interactions with the resident microbiome. Under field conditions, the BCA Aureobasidium pullulans was applied as a model organism to organically grown strawberries during two subsequent years (2011, 2012), either as single strain treatment or with the co-application of the entomopathogenic fungus Beauveria bassiana. Fungal and bacterial communities of strawberry leaves were investigated by means of plate counts and 454 pyrosequencing. The establishment of the introduced A. pullulans strains considerably differed between the two years, presumably due to distinct environmental conditions....

Band-steaming is a new method that may reduce the need for hand-weeding in demanding row crops like carrot and drilled onion. Band-steaming only affects a soil volume equal to the intra-row area of the subsequent crop, and effectively kills the weed seeds in this soil volume. Side-effects on beneficial soil organisms are minimized as compared to current steaming technology, but still need to be assessed.

Provedor de dados: 21
Autores: Daniel, Claudia; Pfammatter, W; Kehrli, P; Wyss, Eric.
Application of processed kaolin particle film repels insects without lethal effects; hence side effects on beneficial arthropods are low. Processed kaolin may be an alternative to broad-spectrum insecticides used against European pear sucker, Cacopsylla pyri (L.), in organic and conventional pear production.   Trials showed that the processed kaolin showed a very high efficacy, and the population of C. pyri was kept under a damaging level over the whole season. In conclusion, kaolin shows promise as an alternative control for C. pyri in organic and orchards of Integreted Pest Management.

The activity of indigenous enzymes; alkaline phosphatase, lactoperoxidase, xanthine oxidase and -glutamyl transpeptidase was evaluated. Mainly the infusion temperature was determinant for inactivation. Whey protein denaturation represented by -lactoglobulin increased significantly with infusion temperature. The non-standardised milk had a higher denaturation rate than skimmed milk. The effect of instant infusion on pH and milk fat globule size in relation to...

CAUSES OF SOIL MALFUNCTIONING IN DEGRADED AREAS OF EUROPEAN AND TURKISH VINEYARDS
Provedor de dados: 21
Autores: Costantini, E.A.C.; Priori, S.; Giffard, B.; Fulchin, E.; Tardaguila, J.; Schroers, H.J.; Pelengic, R.; Akca, E.; Tangolar, S.; Valboa, G.
A study was carried out in nineteen vineyards of five countries, well representative of major viticultural districts, which showed areas with fertility problems, consequence of strong soil erosion occurred during either pre-planting or ordinary cultivation. The comparison between degraded and non-degraded areas highlighted that the soil features limiting water nutrition and enhancing potential water stress were the most frequent discriminant soil conditions. Low nitrogen availability was the second most important cause of soil malfunctioning, together with low organic matter content. The degradation was also reflected in the very low values of the C/N ratio, pointing to a difficulty of microbiota in synthetizing humus. Other limiting factor were excessive...

The direct payment system of the Common Agricultural Policy (CAP) provides income transfers to European farmers. Recently, several countries including England and Sweden have advocated the elimination of direct payments after 2013. The extent to which an elimination of direct payments would affect the land use dynamics in Europe including impacts on structural change and the environment has not been addressed in the existing literature. In this paper, we combine participatory methods, to analyze regional preferences for functions and effects of agriculture, and farm-level modeling, to assess the impacts of such a policy change on farm structures and land use intensities in four European regions located in Germany, Denmark, Italy and Poland, each with...

Modelling of earthworm population dynamics in agricultural soils (First draft)
Provedor de dados: 21
Autores: Axelsen, Jørgen Aagaard; Holmstrup, Martin.
Earthworms are known to play a role in the nitrogen mineralisation in agricultural soils.  Here we present simulations of the population dynamics of two earthworm species that are dominating in danish arable land, and compare the simualtions with observed densities (number and biomass) of the two species from three fields in Denmark. The simulations show an acceptable fit to the observations. The simulation model is used to quantify the impact of the observed earthworm populations on the minearalisation of nitrogen and in turn the crop production.  The simulations show an increase in yield due to the earthworm contribution to mineralisation, and that the earthworms can be responsible for about 1/3 of the biologically mineralised nitrogen.

Biological processes dominate phosphorus dynamics under low phosphorus availability in organic horizons of temperate forest soils
Provedor de dados: 21
Autores: Pistocchi, Chiara; Mészáros, Éva; Tamburini, Federica; Frossard, Emmanuel; Bünemann, Else Katrin.
Understanding the mechanisms underlying phosphorus (P) availability is important to predict forest productivity in a changing environment. We quantified P fluxes and traced P from plant litter into inorganic and organic soil P pools in organic horizons from two contrasting temperate forest soils with low and high inorganic P availability, respectively. We incubated the two organic horizons with and without litter after labelling the soil solution with 33P and performed sequential extractions at several time points in order to trace P dynamics in labile (water-extractable, available and microbial P) and non-labile (non-living organic P, P bound to iron and aluminium and P bound to calcium) pools. Under low P availability, P fluxes were dominated by gross P...

Linking N2O emissions from biochar-amended soil to the structure and function of the N-cycling microbial community
Provedor de dados: 21
Autores: Harter, Johannes; Krause, Hans-Martin; Schüttler, Stefanie; Ruser, Reiner; Fromme, Markus; Scholten, Thomas; Kappler, Andreas; Behrens, Sebastian.
Nitrous oxide (N2O) contributes 8% to global greenhouse gas emissions. Agricultural sources represent about 60% of anthropogenic N2O emissions. Most agricultural N2O emissions are due to increased fertilizer application. A considerable fraction of nitrogen fertilizers are converted to N2O by microbiological processes (that is, nitrification and denitrification). Soil amended with biochar (charcoal created by pyrolysis of biomass) has been demonstrated to increase crop yield, improve soil quality and affect greenhouse gas emissions, for example, reduce N2O emissions. Despite several studies on variations in the general microbial community structure due to soil biochar amendment, hitherto the specific role of the nitrogen cycling microbial community in...

Bioavailability and nutritional effects of carotenoids from organically and conventionally produced carrots in healthy men
Provedor de dados: 21
Autores: Stracke, B.A.; Rüfer, C.E.; Bub, A.; Briviba, K.; Seifert, S.; Kunz, C.; Watzl, B.
It has been hypothesised that organically grown vegetables are healthier than conventionally produced ones due to a higher content of phytochemicals. However, few data from controlled human studies exist. The aim of the present study was to compare the carotenoid content and antioxidant capacity of organically and conventionally produced carrots under defined conditions. Furthermore, a human intervention study was conducted to compare bioavailability, plasma antioxidant capacity, endogenous DNA strand breaks and immune parameters in healthy men ingesting carrots from different agricultural systems. Thirty-six volunteers consumed either organically or conventionally produced blanched carrots (200 g/d; 2 weeks) or no carrots in a double-blind, randomised...

Provedor de dados: 21
Autores: Paull, John.
Green Harvest is an introduction to four Australian organic farmers and gardeners. Each example is framed within the context of an historical account which is itself subsumed within Jones’ own “four key principles” of organics. At the outset, the author alerts us to her view that “History is both fact and fiction” (p.ix). It is a novel approach which will not appeal to all, and will be unsettling for some. The author states that: “Environmental history is the lens through which I have examined organic growers’ changing ideas about  health and environment” (p.ix). The author claims that: “I have identified four key principles, each founded on organic farmers’ and gardeners’ belief in the dependence of health on the biophysical environment. These four...

Motivations for swiss lowland farmers to conserve biodiversity: Identifying factors to predict proportions of implemented ecological compensation areas
Provedor de dados: 21
Autores: Gabel, Vanessa M.; Home, Robert; Stolze, Matthias; Pfiffner, Lukas; Birrer, Simon; Köpke, Ulrich.
The global loss of biodiversity is one of the major environmental threats of our time (Rockstrom et al., 2009) and agriculture is one of the main drivers of the global biodiversity decline (Benton, 2007; Kleijn et al., 2009; Pereira et al., 2010). Agricultural landscapes were formerly rich in biodiversity, which has been attributed to mosaic style landscapes and low-intensity production systems that provided a wide variety of interlinked habitats (Edwards et al., 1999). Economic pressure has led to declining species richness as agricultural production has become more intensive (Robinson and Sutherland, 2002), with an associated reduction of habitat-providing landscape elements (Billeter et al., 2008). Despite the objective of promoting biodiversity, which...

Crop yield and soil fertility response to reduced tillage under organic management
Provedor de dados: 21
Autores: Berner, Alfred; Hildermann, Isabell; Fliessbach, Andreas; Pfiffner, Lukas; Niggli, Urs; Mäder, Paul.
Conservation tillage (no-till and reduced tillage) brings many benefits with respect to soil fertility and energy use, but it also has drawbacks regarding the need for synthetic fertilizers and herbicides. Our objective was to adapt reduced tillage to organic farming by quantifying effects of tillage (plough versus chisel), fertilization (slurry versus manure compost) and biodynamic preparations (with versus without) on soil fertility indicators and crop yield. The experiment was initiated in 2002 on a Stagnic Eutric Cambisol (45% clay content) near Frick (Switzerland) where the average annual precipitation is 1000 mm. This report focuses on the conversion period and examines changes as tillage intensity was reduced. Soil samples were taken from the 0-10...

Ein Lagerversuch mit Möhren aus biologisch-dynamischem Anbau

Einleitung:   Alle Substanzen der Möhre werden nur durch das ihnen übergeordnete Prinzip des Lebens so gestaltet und bewahrt, dass sie eben als das erscheinen, was wir dann als knackige Möhre mit bestimmtem Geruch und Farbe wahrnehmen können. Ist diese innere Kraft der Möhre innewohnende Kraft aber unzureichend, so entgleiten die Stoffe dem Gesamtverband, und die Möhre verfault. In diesem Moment werden die Mineralstoffe tatsächlich wieder zu dem, was sie ohne die Eingliederung in das Leben sind, nämlich tote Substanzen. Der Mensch, der eine Möhre - oder eine andere Frucht - verzehrt, braucht aber nicht nur die toten Mineralstoffe, sonst könnte er auch prächtig gedeihen mit diesen in Tablettenform. Das tut er nicht. Er braucht zusätzlich die Möglichkeit,...

É útil trabalhar com um modelo das práticas de pesquisa científica segundo o qual existem três momentos-chave nos quais é preciso fazer escolhas, a saber, os momentos de: (i) adotar uma estratégia (ou regras metodológicas), (ii) aceitar teorias e (iii) aplicar o conhecimento científico. Os valores sociais podem ter papéis legítimos e importantes no primeiro e no terceiro momentos, porém não no segundo, quando apenas os valores cognitivos e os dados empíricos disponíveis têm papéis essenciais. A distinção entre valores cognitivos e valores sociais é necessária para sustentar este modelo e, portanto, para apoiar a visão de que o conhecimento científico imparcial pode ser o resultado de um processo influenciado por valores sociais, e também para indicar como...

Reply of mulch systems on weeds and yield components  in potatoes
Provedor de dados: 21
Autores: Dvorak, Petr; Tomasek, Jaroslav; Hamouz, Karel; Kuchtova, Perla.
Surface mulch is an important factor of soil protection technology in the cultivation of potatoes. Presented herein are the results of three years (2009–2011) of field trials at two sites (Leškovice and Uhříněves), where two cultivars (Finka and Katka) were grown. Three mulching treatments (grass mulch after planting, grass mulch before germination and black polypropylene mulch textile) were used in the study. The weight of marketable tubers (tuber over 40 mm) and tuber size distribution were influenced significantly by mulching. The application of grass mulch on surface of the row ensured a 20.5–24.8% increase of weight of marketable tubers and higher occurrence of tubers over 56 mm (resp. tubers 56–60 mm and over 60 mm). There was no consistent effect of...

Concepts and Strategies of Organic Plant Breeding in Light of Novel Breeding Techniques
Provedor de dados: 21
Autores: Nuijten, Edwin; Messmer, Monika M.; Lammerts van Bueren, Edith T.
In this paper, we describe the development of a set of guiding principles for the evaluation of breeding techniques by the organic sector over time. The worldwide standards of organic agriculture (OA) do not allow genetic engineering (GE) or any products derived from genetic engineering.  The standards in OA are an expression of the underlying principles of health, ecology, fairness and care. The derived norms are process and not product oriented. As breeding is considered part of the process in agriculture, GE is not a neutral tool for the organic sector. The incompatibility between OA and GE is analyzed, including the “novel breeding techniques”. Instead, alternative breeding approaches are pursued based on the norms and values of organic agriculture not...

Anaerobic co-digestion of grass and forbs – Influence of cattle manure or grass based inoculum
Provedor de dados: 21
Autores: Cong, W.-F.; Moset, V.; Feng, L.; Møller, H.B.; Eriksen, J.
Anaerobic co-digestion of agricultural by-products or wastes with complementarity characteristics is commonly used to enhance methane yield. This study firstly explores the possibility of co-digesting grass and forb species (white clover, chicory and plantain) differing in nutrient composition in enhancing methane yield. This was examined with two inocula (a cattle manure-based inoculum and a grass-based inoculum) in a batch assay. Results showed that co-digesting grass and forbs synergistically enhanced methane yield potential on average by 31 L kg−1 volatile solids (+11%) and reduced lag phase time by 0.8 day in the grass-based inoculum, but not in the cattle manure-based inoculum. Mixtures containing plantain showed more consistent synergistic effect...

Autores: Manici, L.; Donatelli, M.; Fumagalli, D.; Lazzari, A.; Bregaglio , S.
A study was carried out on the potential response of soil-borne pathogens causing crop yield losses under a climate change scenario in Europe. A controlled chamber set of experiments was carried out to quantify pathogen response to temperature using pure colonies of three soil-borne fungi, representative of low (Fusarium nivale), medium-high (Athelia rolfsii) and high (Macrophomina phaseolina) temperature requirements. A generic model to simulate fungal growth response to temperature based on these experiments was developed and linked to a soil temperature model component, and to components to simulate soil water content accounting for crop water uptake of potential hosts. Pathogens relative growth was simulated over Europe using the IPCC A1B emission...

In an intercropping lettuce-carrot system submitted to crescent dosages of organic compost (0; 12; 24; 48 Mg ha-1) were monitored carbon from soil microbial biomass (MBC), labile carbon in fumigated soil (LCF), in non-fumigated soil (LCNF), in autoclaved soil (LCA) and total organic carbon (TOC) at 0-10 cm of depth. Pasture and forest areas surrounding the experiment were used as reference. Five samples from soil were evaluated at 8 days before the beginning of the experiment, 0; 6; 60 and 114 days after manuring (dam). LCF was the attribute that presented the most consistent correlation with TOC that is usually utilized to detect changes in soil organic matter. Increasing dosages of organic compost caused the increase of MBC, LCF, LCNF, LCA and TOC. From...

Exploring hair cortisone concentration as a novel tool to assess chronic stress in sheep With tick-borne Fever
Provedor de dados: 21
Autores: Stubsjøen, Solveig Marie; Sørheim, Kristin; Chincarino, Matteo; Bolin, Jon; Brunberg, Emma; Fuchs, Boris; Palme, Rupert; Grøva, Lise.
Tick-borne fever (TBF), caused by the bacterium Anaplasma phagocytophilum and transmitted by the tick Ixodes ricinus, has considerable consequences for animal welfare and economy in the sheep industry. Non-invasive, objective methods to quantify chronic stress are needed in order to evaluate the welfare impact of disease. The aim of this study was 1) to evaluate hair cortisol (HC) and hair cortisone (HCn) as biomarkers of chronic stress in sheep with TBF and 2) to test whether there was an association between the development of TBF and concentrations of HC, HCn and faecal cortisol metabolites (FCM) and body weight. The experiment took place in an area with a high prevalence of TBF, and thirty lambs were used in the study. Wool samples were collected in...

Effects  of the repeated distribution of sainfoin hay on the resistance and the resilience of goats naturally infected with gastrointestinal nematodes
Provedor de dados: 21
Autores: V., Paolini; F., De La Farge; F., Prevot; Ph., Dorchies; H., Hoste.
Due to the high prevalence of anthelmintic resistance in goats, the need to explore novel approaches to control nematodes and  to reduce the exclusive reliance on chemotherapy is strongly demanded in this host species. In sheep, several studies have shown  that the consumption of tannin-rich legume forages was associated with positive effects on host resilience and resistance to  parasite infection. In goats, studies on such interactions between tanniferous plants and nematode infections remain few. The  objectives of the current study were to examine under natural conditions the effects of consumption of sainfoin hay by goats on  the parasite populations and on host resilience.  Eighteen adult cull goats naturally infected with Haemonchus contortus,...

Økologipolitikken og de økologiske interesseorganisationernes kapaciteter i Danmark, Sverige og Tyskland
Provedor de dados: 21
Autores: Daugbjerg, Carsten; Møller, Dan Kristian.
Økologisk jordbrug kom i de nordeuropæiske lande på den politiske dagsorden i 1980’erne. Det ændrede markant vilkårene for de organisationer, der repræsenterede det økologiske jordbrug, og påvirkede den måde de udviklede sig på. I Danmark blev økologisk jordbrug defineret som en nicheproduktion, og først senere fik det miljøpolitiske aspekt en vis vægt. I Sverige har man defineret økologisk jordbrug som et miljøpolitisk instrument, mens det i Tyskland først blev set som en måde at begrænse EU's overskudsproduktion på og senere som en forbrugerbeskyttelsesforanstaltning. Disse forskellige opfattelser af, hvilke policy-problemer det økologiske jordbrug kan løse, har påvirket de økologiske interesseorganisationers udvikling af kapaciteter vidt forskelligt i...

The effect of catch crops on sulphate leaching and availibility of S in the succeeding crop on sandy loam soil in Denmark
Provedor de dados: 21
Autores: Eriksen, J; Thorup-Kristensen, K.
Sulphate leaching losses may reduce the long-term possibility of maintaining the S supply of crops in low input farming systems. The ability of catch crops (Italian ryegrass [Lolium multiflorum Lam], winter rape [Brassica napus L.] and fodder radish [Raphanus sativus L.]) to reduce soil sulphate concentrations in autumn and make it available to a succeeding crop was investigated in 1996-98 on sandy loam soil in Denmark. All catch crops reduced soil sulphate concentrations in the autumn compared to bare soil. Especially the cruciferous catch crops had the ability to deplete efficiently soil sulphate levels and thus, reduce the sulphate leaching potential. The S uptake in aboveground catch crop was 8, 22 and 36 kg S ha-1 for ryegrass, winter rape and fodder...

Consumer preferences for additional ethical attributes of organic food
Provedor de dados: 21
Autores: Zander, Katrin; Hamm, Ulrich.
This paper examines the relevance of additional ethical attributes of organic food for consumers’ purchase decisions. By means of an Information-Display-Matrix (IDM) and an accompanying consumer survey, the information acquisition behaviour of consumers regarding seven additional ethical attributes and the product price of organic food was investigated in five European countries. The ethical attributes, ‘animal welfare’, ‘regional production’ and ‘fair prices to farmers’ turned out to be the most important. The results also show that the vast majority of consumers of organic food was willing to pay higher prices for organic products with additional ethical attributes. Contrasting the results with those from direct inquiry by means of a ‘single source...

Maintaining Trust and Credibility in a Continuously Evolving Organic Food System
Provedor de dados: 21
Autores: Thorsøe, Martin H.
Credibility is particularly important in organic food systems because there are only marginal visual and sensorial differences between organic and conventionally produced products, requiring consumers to trust in producers’ quality claims. In this article I explore what challenges the credibility of organic food systems and I explore how credibility of organic food systems can be maintained, using the Danish organic food system as a case study. The question is increasingly relevant as the sale of organic food is growing in Denmark as well as globally, and consumers’ expectations of organics continuously evolve. The inquiry is threefold, first I outline a conceptual framework for understanding trust and credibility in the food system, secondly I explore the...

Provedor de dados: 21
Autores: Daniel, Claudia; Collier, Rosemary; Thomas, Jane; Hommes, Martin.
Abstract: Pests and pathogens of Brassica vegetables and oilseed rape are mainly managed at a field level. Management of pest insects at a farm level is only suitable for farmers owning compact areas of land, which is not the case in many central European areas. This paper discusses the effects of landscape and region on pests and pathogens in Brassica crops. Topics covered include pest and disease dispersal and persistence, regional races or biotypes, new pests and pathogens, insecticide resistance, conservation biocontrol and monitoring and forecasting.

Basal organic phosphorus mineralization in soils under different farming systems
Provedor de dados: 21
Autores: Oehl, F.; Frossard, E.; Fliessbach, A.; Dubois, D.; Oberson, A.
Soil organic P (Po) mineralization plays an important role in soil P cycling. Quantitative information on the release of available inorganic P (Pi) by this process is difficult to obtain because any mineralized Pi gets rapidly sorbed. We applied a new approach to quantify basal soil Po mineralization, based on 33PO4 isotopic dilution during 10 days of incubation, in soils differing in microbiological activity. The soils originated from a 20 years old field experiment, including a conventional system receiving exclusively mineral fertilizers (MIN), a bioorganic (ORG) and bio-dynamic (DYN) system. Indicators of soil microbiological activity, such as size and activity of the soil microbial biomass and phosphatase activity, were highest in DYN and lowest in...

Bio allein macht nicht gesünder. Aber Bioprodukte sind Bestandteil eines nachhaltigen und gesunden Ernährungsstils. Die meistgenannten Erwartungen von Konsumentinnen und  Konsumenten an Bioprodukte lassen sich wie folgt zusammenfassen: keine Pestizidrückstände, besserer Geschmack, besser für Gesundheit und Umwelt. Ein Überblick über die verfügbare Fachliteratur zeigt, dass Bioprodukte diese Erwartungen meist erfüllen. Die Frage, wie sich die gefundenen Unterschiede auf die menschliche Gesundheit auswirken, ist jedoch experimentell noch wenig erforscht.

Autores: Bennedsgaard, Torben Werner; Thamsborg, Stig Milan; Vaarst, Mette; Enevoldsen, Carsten.
This paper focuses on the changes in production, herd health and veterinary treatments in Danish organic dairy herds during approximately eleven years based on historic data from herds converted to organic milk production before 1990 (old organic herds) compared to herds converted in 1995 and 1999-2000 and herds that are still conventional.  Herd size, milk production, the shape of the lactation curve, somatic cell counts and veterinary treatments for mastitis, retained placenta and ketosis are compared over time and between herd groups.  The old organic herds differed from the other three herd groups by having lower milk production per cow, lower somatic cell counts and fewer treatments of mastitis. Herds converted in 1995 and 1999-2000 were comparable to...

BACKGROUND  The potential of hyperspectral imaging (500–1010 nm) was evaluated for monitoring of the quality of potato slices (var. Anuschka) of 5, 7 and 9 mm thickness subjected to air drying at 50 °C. The study investigated three different feature selection methods for the prediction of dry basis moisture content and colour of potato slices using partial least squares regression (PLS).    RESULTS  The feature selection strategies tested include interval PLS regression (iPLS), and differences and ratios between raw reflectance values for each possible pair of wavelengths (R[λ1]–R[λ2] and R[λ1]:R[λ2], respectively). Moreover, the combination of spectral and spatial domains was tested. Excellent results were obtained using the iPLS algorithm. However,...

Aeromonas media in compost amendments contributes to suppression of Pythium ultimum in cress
Provedor de dados: 21
Autores: Oberhaensli, T.; Hofer, V.; Tamm, L.; Fuchs, J. G.; Koller, M.; Herforth-Rahmé, J.; Maurhofer, M.; Thuerig, B.
Soil-borne diseases such as damping-off caused by Pythium sp. are responsible for high yield losses in organic vegetable production and are difficult to control. Compost amendments have been shown to improve in many cases survival and growth of plants in soils infested with soil-borne diseases. Yet, not all composts are disease suppressive and suppressiveness of composts can be pathogen-specific. Cress (Lepidium sativum L.) was grown in a standard peat substrate amended either with coco fiber (conducive control) or with composts differing in their suppressiveness towards Pythium ultimum. Bacteria were isolated from the rhizoplane and the most abundant species identified by MALDI-TOF MS. The bacterial composition in the rhizoplane of plants grown in...

Evaluation of Calcium Hydroxide (Ca(OH)2) Used in Footbaths as Treatment and Prevention of Digital Dermatitis in Danish Dairy Cattle
Provedor de dados: 21
Autores: Rasmussen, A.S.; Bennedsgaard, T.W.; Capion, N.
Digital dermatitis is a major problem in the dairy  production in many countries. Footbaths have been the preferred method in the control of digital dermatitis, and various products are used in despite of a lack of scientific evidence of the effect.  The objective was to evaluate calcium hydroxide (Ca(OH)2) used in footbaths as treatment and prevention of digital dermatitis. The study was conducted as a clinical trial in 4 commercial Danish dairy herds including 405 cows. Ca(OH)2 is an alkaline disinfectant which is recommended in footbaths to control digital dermatitis by some Danish hoof trimmers. The footbath used in the study was a commercial available split-footbath, which made it possible to treat one side of the cow and using the other side as a...

Autores: Leiber, Florian.
Für die wissenschaftliche Beurteilung ökologisch und insbesondere biologisch-dynamisch erzeugter Lebensmittel besteht ein häufig formulierter Anspruch an eine «ganzheitliche Betrachtungsweise». Diese kann sich zum einen auf eine umfassende Berücksichtigung aller bei der Erzeugung in Betracht kommenden Faktoren beziehen, sie ist aber auch so zu verstehen, dass das Lebensmittel selbst als eine unauftrennbare Einheit angeschaut wird, die sich nicht bausteinartig aus einzelnen Inhaltsstoffen zusammensetzen lässt. Andererseits kommt aber gerade einzelnen molekularen Inhaltsstoffen in der Qualitätsbeschreibung von ökologischen Lebensmitteln eine hohe Bedeutung zu – sei es als unerwünschte Giftstoffe, sei es als erwünschte essentielle Vitamine, Fettsäuren,...

Nitrogen and carbon release during decomposition of roots and shoots of leguminous green manure crops
Provedor de dados: 21
Autores: Talgre, Liina; Roostalu, Hugo; Maeorg, Erkki; Lauringson, Enn.
In Nordic conditions, soils are frozen during winter, affecting the decomposition rates of crop residues. Hence, the decomposition rates of above- and underground biomass and the dynamics of the N and C released into the soil were studied in trials focused on green manure crops. The decomposition of the residue and N release from the residue varied among the five species of legume tested. There was a marked difference in decomposition rates between shoots and roots, which may also be explained by the differences in the chemical composition of the residue. The shoot residue decomposes rapidly and it serves as a source of N for the subsequent crop. The root residue decomposes more slowly and this had a positive effect in a crop rotation in the second year....

Autores: G., Lien; O., Flaten; A., Korsaeth; K.D., Schumann; J.W., Richardson; R., Eltun; J.B., Hardaker.
The aim of this study was to compare risk of organic, integrated and conventional cropping systems. Experimental cropping system data (1991-1999) from eastern Norway were combined with farm budget data. Empirical distributions of net farm income for different cropping systems were estimated with a simulation model. The results show that the organic system had the greatest net farm income variability, but both the existing payment system and organic price premiums make it the most economically viable alternative.

Weeds, insect fauna, and the lack of food chains in conventional cereal fields
Provedor de dados: 21
Autores: Bruus, Marianne; Axelsen, Jørgen Aagaard; Tybirk, Knud.
Weeds are important as food for both herbivorous insects and farmland birds. Especially monophagous, herbivorous insects depend on the presence of one or a few weed species, and consequently a shortage of such weed species may hamper parts of the food web of the agricultural ecosystem. In any ecosystem on the earth food webs and food chains are expected, i.e. that there are species from one trophic level feeding on the lower trophic levels. These levels may be organised as organic matter – degrader, plant – herbivore and predator – prey, where preys may be degraders, herbivores and other predators. In describing ecosystems the trophic connections are often described as nodes linking species from one trophic level to another, and in most ecosystems it is...

Autores: Döring, T. F.; Hiller, A.; Wehke, S.; Schulte, G.; Broll, G.
Carabids, a species rich arthropod family, potentially contribute  much to biodiversity in agroecosystems, but assessing and  monitoring carabid diversity is costly and time consuming.  Therefore, this study aimed at finding more easily measurable  parameters indicating high carabid diversity within organic and  conventional management systems. Cover and number of weed  species as well as activity density of single carabid species and of  total carabids were investigated as potential indicators of carabid  species richness. The study was carried out near Reckenfeld in  Westphalia on sandy Plaggenesch soils. Three organically and  four conventionally managed fields (cereals and corn) were  investigated at the field margins and in the field centres from...

Autores: Kopta, Tomáš; Pokluda, Robert.
A marketable production characterized by stem weight, leaf area and leaf/stem ratio were measured in five cultivars of Chinese broccoli. From the results can be concluded the cultivar Hon Tsai Tai as significantly worst performing (stem weight 15,5 g, leaf/stem ratio 29 cm2.g1-) and cultivar Happy Rich as significantly best (stem weight 55 g, leaf/stem ratio 18,6 cm2.g1-). Other cultivars such as Summer Jean, Suiho and Green Lance were in between in this evaluation. Cultivar Happy Rich can be consequently recommended for summer production under organic growing conditions in the Czech Republic.

Autores: Oudshoorn, Frank; Kristensen, Troels; Nadimi, Esmaeil.
The objective of this paper was to investigate the effect of limited grazing time on urination and defecation frequency, spatial distribution of excrement in the paddock, and the resulting nitrogen balance at animal and field level. During a 6-week period in early summer, 60 Holstein Frisian dairy cows (31.0±5.4 kg ECM) were randomly allocated to three different treatments, with grazing at clover-grass pasture during daytime for 4, 6.5 or 9 h daily. Indoor feeding, with a mixture of roughage and concentrates (13% crude protein), was restricted for treatment 4 and 6.5 h to the amount the 9-h treatment could eat. Cows allowed grazing at pasture for 4 h moved more rapidly during pasture, moved longer distance per active hour and used a higher proportion of...

Assessing the ecological soundness of organic and conventional agriculture by means of life cycle assessment (LCA) - a case study of leek production
Provedor de dados: 21
Autores: de Backer, Eline; Aertsens, Joris; Vergucht, Sofie; Steurbaut, Walter.
Purpose – Sustainable agriculture implies the ability of agro-ecosystems to remain productive in the long-term. It is not easy to point out unambiguously whether or not current production systems meet this sustainability demand. A priori thinking would suggest that organic crops are environmentally favourable, but may ignore the effect of reduced productivity, which shifts the potential impact to other parts of the food provision system. The purpose of this paper is to assess the ecological sustainability of conventional and organic leek production by means of life cycle assessment (LCA).     Design/methodology/approach – A cradle-to-farm gate LCA is applied, based on real farm data from two research centres. For a consistent comparison, two functional...

STANDARDS AND COMPLIANCE SYSTEMS FOR ORGANIC AND BIO-DYNAMIC AGRICULTURE  IN AUSTRALIA:PAST, PRESENT AND FUTURE
Provedor de dados: 21
Autores: Wynen, Els.
Australia does not yet have standards for organic and bio-dynamic produce for the domestic market, although there are standards for exports. Recently, there has been a move towards the establishment and adoption of standards for the domestic market. Debate has centred on which organisation would be most suitable to host such standards. An important issue was the acceptability of the final standards to the Government, so that it would be willing to legalise the word ‘organic’ according to those standards. Other issues of concern were ownership of and control over the standards, copyright, compliance with the standards, and costs of developing and maintaining standards. Given the requirements identified by the industry as being of importance, the process of...

Organizational resilience emphasizes the adaptive capacity for renewal after crisis. This paper explores the sustainability and resilience of a not-for-profit firm that claims to contribute to sustainable development of the food system. We used semi-structured interviews and Holling’s adaptive cycle as a heuristic device to assess what constitutes social and sustainable entrepreneurship in this case, and we discuss the determinants of organizational resilience. The business, Biodynamiska Produkter (BP), has experienced periods of growth, conservation and rapid decline in demand, followed by periods of re-organization. Our results suggest that BP, with its social mission and focus on organic food, meets the criteria of both a social and sustainability...

Factors influencing the perception of organic certification logos in Turkey
Provedor de dados: 21

Consumers’ perceptions on organic certification logos and the factors influencing these perceptions were explored. Data from surveys conducted   in major cities of Turkey revealed that organic food consumers had little knowledge about logos, although the declared level of trust in organic logos was high. According to ordered logit models, consumer’s perceptions on organic certification logos were influenced by purchasing frequency and weight of organic foods in total food consumption. Dummy variables representing additional private certification company logos as well were generally found to have a significant effect on logo perception. This result suggests that consumers’ attitudes towards these logos and towards the governmental logo are not the same....

The farmer field school (FFS) is a concept for farmers’ learning, knowledge exchange, and empowerment that has been developed and used in developing countries. In Denmark, a research project focusing on explicit nonantibiotic strategies involves farmers who have actively expressed an interest in phasing out antibiotics from their herds through promotion of animal health. One way of reaching this goal was to form participatory focused farmer groups in an FFS approach, which was adapted to Danish conditions and named “stable schools.” Four stable schools were established and went through a 1-yr cycle with 2 visits at each of the 5 or 6 farms connected to each group. A facilitator was connected to each group whose role was to write the meeting agenda together...

Crop yield, weed infestation and soil fertility responses to contrasted ploughing intensity and manure additions in a Mediterranean organic crop rotation
Provedor de dados: 21
Autores: Baldivieso-Freitas, P.; Blanco-Moreno, José Manuel; Armengot, Laura; Chamorro, Lourdes; Romanyà, Joan; Sans, F. Xavier.
Conservation agriculture and organic farming are two alternative strategies that aim to improve soil quality and fertility in arable cropping systems through the deployment of different practices, that are rarely combined. While conservation agriculture practices include reducing tillage intensity and maintaining soil cover all year round to prevent soil erosion, organic farming focuses on nutrient recycling, using farmyard manure and green manure to enhance soil quality. However, these practices are not free from side-effects, such as increasing weed infestation or limited nutrient availability. Therefore it is necessary to explore the sustainability of their combination under local environmental constraints. The objectives of this study were to evaluate...

Background and aims  We investigated whether the incorporation of intercropped white clover as a split-dose fertiliser improves N retention of the plant-soil system in leek production.    Methods  White clover and leek were grown in pots where clover was stepwise incorporated into soil as fertiliser. Half of the clover was incorporated before leek transplantation (LT), the other half was incorporated 26 (S1) or 41 (S2) days after LT, compared with full incorporation of all clover (F) before LT. 15N injection and leaching studies were performed to investigate interspecific competition and the effects of precipitation on soil N availability.    Results  Stepwise incorporations increased or had no effect on leek growth, despite competition for N between white...

The scarcity of non-renewable resources such as soils and fertilizers and the consequences of climate change can dramatically influence the food security of future generations. Mutualistic root microorganisms such as plant growth-promoting rhizobacteria (PGPR) and arbuscular mycorrhizal fungi (AMF) can improve plant fitness. We tested the growth response of wheat (Triticum aestivum [L.]), rice (Oriza sativa [L.]) and black gram (Vigna mungo [L.], Hepper) to an inoculation of AMF and PGPR alone or in combination over two years at seven locations in a region extending from the Himalayan foothills to the Indo-Gangetic plain. The AMF applied consisted of a consortium of different strains, the PGPR of two fluorescent Pseudomonas strains (Pseudomonas jessenii,...

Provedor de dados: 21
Autores: Maurer, V.; Holinger, M.; Amsler, Z.; Früh, B.; Wohlfahrt, J.; Stamer, A.; Leiber, F.
Insects will likely play an important role as protein sources for livestock in the future. Many insect species are able to convert materials not suitable for human nutrition – or even waste – into valuable protein with a favourable amino acid composition for poultry and other livestock. A feeding trial with partly de-fatted meal of dried Hermetia illucens larvae (Hermetia meal) reared on vegetarian by-products of the pasta and convenience food industry was carried out in small groups of Lohmann Selected Leghorn laying hens (four rounds, 10 hens/round). Experimental diets H12 and H24 contained 12 and 24 g/100 g Hermetia meal replacing 50 or 100% of soybean cake used in the control feed, respectively. After three weeks of feeding experimental diets, there...

Microbial response of soils with organic and conventional management history to the cultivation of Bacillus thuringiensis (Bt)-maize under climate chamber conditions
Provedor de dados: 21
Autores: Fliessbach, Andreas; Nietlispach, Bruno; Messmer, Monika; Rodríguez-Romero, Ana-Sue; Mäder, Paul.
An experiment was carried out in a climate chamber to analyse if Bt-maize may cause particular changes in soils with different levels of microbial biomass and activity due to long-term management history. Among the soils selected, the ones managed organically for 30 years exhibited twice the microbial biomass and 2.6 times the dehydrogenase activity (DHA) of the soil from a field with long-term conventional maize monoculture. Soils were cultivated twice in a row with Bt-maize, its near-isogenic line and a conventional breeding line. We tested the hypotheses that (a) soil microbial biomass and activity are affected by the cultivation of Bt-maize and that (b) the influence of Btmaize depends on the level of soil microbial biomass and activity.

Autores: Marchi, Chiara; Andersen , Liselotte Wesley; Damgaard, Christian; Olsen, Kent; Jensen, Thomas Secher; Loeschcke, Volker.
The impact of landscape structure and land management on dispersal of populations of wild species inhabiting the agricultural landscape was investigated focusing on the field vole (Microtus agrestis) in three different areas in Denmark using molecular genetic markers. The main hypotheses were the following: (i) organic farms act as genetic sources and diversity reservoirs for species living in agricultural areas and (ii) gene flow and genetic structure in the agricultural landscape are influenced by the degree of landscape complexity and connectivity. A total of 443 individual voles were sampled within 2 consecutive years from two agricultural areas and one relatively undisturbed grassland area. As genetic markers, 15 polymorphic microsatellite loci...

Autores: Lassen, Jesper; Oelofse, Myles.
To avoid the risks of conventionalisation and becoming a modified version of conventional farming, organic farming is under a continuous pressure to reinvent itself by adopting new technologies. This article examines the role of precaution in organic farmers’ assessment of potential new technologies, and how farmer’s assessment draws on different types of knowledge. The article further explores how knowledge type compares to the role of knowledge and precaution set forth in the principles of organic farming by the organic movement (IFOAM). Results from a case study of the introduction of sewage sludge as an alternative – and controversial - source of nutrients in organic agriculture are presented. Empirically, this case study builds on the analysis of five...

Schwefel im Herbst gegen Birnenpockenmilbe
Provedor de dados: 21
Autores: Daniel, Claudia; Wyss, Eric.
Die Birnenpockenmilbe ist ein Schädling, der nur sehr lokal auftritt, dort aber massiven Schaden anrichten kann. Die bisherigen Bekämpfungsstrategien waren unzuverlässig. Mit der Anwendung von Schwefel im Herbst hat das FiBL eine einfache und offenbar sehr wirksame Methode gefunden, um die Milbe in Schach zu halten. Die Methode muss noch bewilligt werden.

Performance and carcass quality of fully on partly outdoor reared pigs in organic production
Provedor de dados: 21
Autores: Strudsholm, Karin; Hermansen, John E.
Outdoor rearing of finishers can be considered a relevant option in organic pig production. The performance and carcass characteristics of 245 organically produced and free-range born crossbred pigs allocated to five treatments were compared. The five treatments were: transfer to a barn with free access to feed (1) at weaning and until slaughter, (2) at a live weight of 40 kg and until slaughter, (3) at live weight of 80 kg and until slaughter, or reared at pasture (4) with free or (5) limited access to concentrates until slaughter. Pigs fed ad libitum fed indoor compared to pigs fed ad libitum outdoor had a significant lower feed consumption (5 MJ ME /kg gain), lower lean percentage (2.3%), and a higher backfat depth (1.1 mm)(all P &lt; 0.05). Compared...

Effects of two contrasted arbuscular mycorrhizal fungal isolates on nutrient uptake by Sorghum bicolor under drought
Provedor de dados: 21
Autores: Symanczik, S.; Lehmann, M. F.; Wiemken, A.; Boller, T.; Courty, P. E.
Drought is a limiting factor for crop production, especially in arid and semi-arid climates. In this study, Sorghum bicolor plants were inoculated, or not, with Rhizophagus irregularis, an arbuscular mycorrhizal (AM) strain typical for temperate climates, or Rhizophagus arabicus, a strain endemic to hyper-arid ecosystems. Plants were grown under well-watered or drought conditions in compartmented microcosms. Transpiration rates, plant growth, and nutrient uptake (using 15N as a tracer) were determined to assess the impact of drought stress on sorghum plants in AM symbiosis. Although AM colonization did not affect the bulk biomass of host plants, R. arabicus improved their transpiration efficiency and drought tolerance more than R. irregularis. Moreover, R....

Autores: Uusitalo, Risto; Turtola, Eila; Grönroos, Juha; Kivistö, Juhani; Mäntylahti, Väinö; Turtola, Ari; Lemola, Riitta; Salo, Tapio.
Soil test phosphorus (P) concentration has a major influence on the dissolved P concentration in runoff from agricultural soils. Thus, trends in soil test P partly determine the development of pollution potential of agricultural activities. We reviewed the changes of soil test P and P balances in Finnish agriculture, and assessed the current setting of P loss potential after two Agri-Environmental Programs. Phosphorus balance of the Finnish agriculture has decreased from +35 kg ha–1 of the 1980’s to about +8 kg P ha–1 today. As a consequence, the 50-yr upward trend in soil test P concentrations has probably levelled out in the late 1990’s, as suggested by sampling of about 1600 fields and by a modelling exercise. For the majority of our agricultural soils,...

Shade trees and tree pruning alter throughfall and microclimate in cocoa (Theobroma cacao L.) production systems
Provedor de dados: 21
Autores: Niether, Wiebke; Armengot, Laura; Andres, Christian; Schneider, Monika; Gerold, Gerhrad.
Shade trees in agroforestry systems protect the understory cocoa from climate extremes. Shade tree pruning manages microclimatic conditions in favor of cocoa production while tree diversity is maintained. Adaptation of pruning has to consider seasonal changes in temperature and precipitation to protect the understory cocoa.  Context  Structural characteristics of tree stands such as species diversity, tree density, and stratification can affect throughfall and microclimate. Pruning changes the canopy and may therefore modulate internal conditions.  Aims  The aim of this study is to assess the environmental growing conditions of cocoa trees.  Methods  We monitored canopy openness and the impact of stand structure on throughfall and microclimate in three...

Effect of toasting field beans and of grass-clover: Maize silage ratio on milk production, milk composition and sensory quality of milk
Provedor de dados: 21
Autores: Mogensen, L.; Vestergaard, J.S.; Frette, X.; Lund, P.; Weisbjerg, M.R.; Kristensen, T.
The effect of toasting field beans and of grass-clover: maize silage ratio on milk production, milk composition and sensory quality of the milk was investigated in a 2*2 factorial experiment. Toasting of field beans resulted in lower contents in milk of both fat (44.2 versus 46.1 g/kg, P = 0.02) and protein (33.5 versus 34.2 g/kg, P = 0.008), whereas milk production and urea and somatic cell contents were unaffected compared with untreated field beans. Increasing the proportion of maize silage (from 2 to 5 kg DM/cow/day) in the ration decreased the content of urea in milk (P=0.002), whereas milk production and fat and protein contents were unaffected. Milk from cows fed the high proportion of maize silage had a lower (P=0.04) content of the long chain...

The development and geographic distribution of organic farming in Ireland
Provedor de dados: 21
Autores: Läpple, D.; Cullinan, J.
This paper explores the development and spatial distribution of organic farming in Ireland. The focus is on the impact of policy, agricultural systems, soil quality, market access, information provision and the influence of neighbouring organic farmers on this development. Geocoded data on organic farms are mapped and spatial concentration is estimated using a location quotient. The results suggest that while organic farming is spread over most of the country, there is evidence of three main spatial clusters. Furthermore, the spatial distribution of organic farming appears to be based on the interaction of a number of determining factors. While certain agricultural systems and soil qualities provide favourable conversion conditions, regional supports,...

Autores: Gambelli, Danilo; Zanoli, Raffaele; Solfanelli, Francesco.
Inspections in organic farming systems are the key tool to assure reliability of the organic business and detection of non-compliant operators. Supporting control bodies in the inspection procedure can increase the efficiency and competitiveness of the sector. Here we propose a decision support system for inspections based on Bayesian networks. Our model is based on statistical information taken from the archives of main Italian control body, and considers decision strategies according to the maximization of expected utility based on risk minimization. © 2012 The authors and IOS Press.

Impacts of organic and conventional dairy farmer attitude, behaviour and knowledge on farm biodiversity in Ireland
Provedor de dados: 21
Autores: Power, Eileen F.; Kelly, Daniel L.; Stout, Jane  C.
Agricultural intensification has caused significant declines in biodiversity. Agri-environmental schemes (AES), including organic farming, are thought to benefit biodiversity. However, under similar production conditions and in comparable locations and schemes, farms are not managed in the same way, with variable consequences for production and the environment. Understanding farmer attitude, behaviour and knowledge of the environment and their impacts on biodiversity may help us understand the variable impacts of AES on biodiversity. We combined a sociological survey of nine organic and eight conventional dairy farmers (measuring environmental and achievement attitudes; environmental and production-orientated behaviours and environmental knowledge), in...

Using vegetation indices in autumn to estimate nitrate leaching during autumn and winter in different cropping systems
Provedor de dados: 21
Autores: Zhao, Jin; De Notaris, Chiara; Olesen, Jørgen E.
Nitrate leaching losses from arable cropping systems cause severe damages to the environmental services worldwide. There is a considerable need for methods that allow rapid, easy and area covering detection of nitrate leaching to guide N management. We used three years of data from the 5th cycle of a long-term crop rotation experiment in Denmark to  quantify the relationships between nitrate leaching in autumn and winter and field conditions in autumn as defined by three vegetation indices [VIs; Ratio Vegetation Index (RVI), Normalized Difference Vegetation Index (NDVI), Ratio Red Edge (RRE)] in autumn. Following cereal crops, catch crops significantly reduced nitrate leaching in autumn and winter, whereas this was only the case for one out of the three...

The implication of stubble tillage for weed population dynamics in organic farming
Provedor de dados: 21
Autores: Pekrun, Carola; Claupein, Wilhelm.
In practical farming early and shallow stubble tillage post-harvest is carried out to stimulate germination of freshly ripened crop and weed seeds, to kill the resulting seedlings and hence to reduce the input into the soil seedbank. Additionally, it aims at reducing perennial weeds by mechanical damage. In this paper field experiments and laboratory studies are presented which show that stubble tillage can reduce perennial weeds. However, it had a variable effect on annual weeds. After five years of experimentation, no effect of stubble tillage was seen when looking at the aboveground vegetation. In contrast, the soil seedbank of the control roughly doubled the seedbank of plots where stubble tillage had been carried out immediately after harvest. These...

Modelling of soil emissions of nitrous oxide (N2O) and carbon dioxide (CO2) is complicated by complex interactions between processes and factors influencing their production, consumption and transport. In this study N2O emissions and heterotrophic CO2 respiration were simulated from soils under winter wheat grown in three different organic and one inorganic fertilizer-based cropping system using two different models, i.e., MoBiLE-DNDC and FASSET. The two models were generally capable of simulating most seasonal trends of measured soil heterotrophic CO2 respiration and N2O emissions. Annual soil heterotrophic CO2 respiration was underestimated by both models in all systems (about 10−30% by FASSET and 10−40% by MoBiLE-DNDC). Both models overestimated annual...

Similarity of technical logics of cropping systems organization between conventional and recently converted organic farmers in a water catchment area
Provedor de dados: 21
Autores: Gratecap, J.B.; Wezel, A.; Casagrande, Marion; Martin, P.
Organic farming is considered as a solution to preserve water quality in drinking water catchments. For local managers of these catchments it is thus important to identify conventional farmers for potential conversion to organic farming. The aim of this article is to assess technical similarity of conventional farmers concerned by a water catchment to organic farming. We build a typology of farmers based on technical logics related to cropping systems organization. We differentiated five types of farmers among 18 conventional dairy farmers and three recently converted organic farmers. According to our results, only two farmers can be considered as close to technical logics identified in organic farms. Nevertheless, we could identify partial technical...

Maintaining sufficient soil phosphorus (P) levels for non-limiting crop growth is challenging in organic systems since off-farm inputs of P are restricted. This study assessed the status of P on organic farms in Europe using soil test results for extractable P. Data was obtained from published literature, unpublished theses, and various national and regional databases of soil test values. Most of the data (15,506 observations) came from field scale soil tests, but in some cases (1272 observations) values had been averaged across a farm. Farm scale and field scale data were analysed separately and the impact of farm type (arable, dairy, grassland, horticulture, mixed, poultry, unknown) was assessed. Soil test results were assigned to P classes from very low...

Mixed grazing with heifers and pregnant sows
Provedor de dados: 21
Autores: Soegaard, Karen; Sehested, Jakob; Danielsen, Viggo.
In 1999, a mixed grazing system with heifers and pregnant soews was compared with grazing systems with heifers and sows alone. Normally, herbage quality used for sow grazing is not optimal for high herbage intake and it was therefore examined whether mixed grazing with heifers could improve the grazing system. Herbage quality and botanical composition of the sward was best where heifers grazed alone, followed by swards with mixed grazing and the poorest quality and composition were in swards where the sows grazed alone. The daily weight gain of the sows tended to be higher and the weight gain of the heifers was significantly higher for mixed than at mono grazing. The mixed grazing system seems to be a usable alternative for grazing sows.

In direct-sowing rice culture using cloth mulch, puddling and leveling (P &amp; L) is usually done 2 days before the mulching (sowing). However, the mulching is very difficult, due to the muddy condition of the soil. Comparative studies were made to observe the effects of the timing of P &amp; L, that is, P &amp; L 10 days before mulching (P10) vs. P &amp; L 2 days before the mulching (P2), on the operator's physical stress, the rice growth, and grain yield. Basal fertilizer was applied 2 days before the mulching in the P2 treatment (P2-B2), and topdressing was applied at 29 days before heading in all treatments. For the P10 treatment, timing of the basal fertilization was set at 14 (P10-B14) or 3 (P10-B3) days before the mulching.  Results revealed that...

Provedor de dados: 21
Autores: Dvorak, Petr; Hamouz, Karel; Kuchtová, Perla; Tomasek, Jaroslav.
Cílem tohoto pokusu bylo zhodnotit vliv travního mulče a termínu jeho aplikace na výnos a počet konzumních hlíz a na velikostní zastoupení hlíz pod trsem. V roce 2008 byl travní mulč aplikován na hrůbky brambor zaloţené v ekologickém způsobu hospodaření. V pokusu byly srovnávány dvě varianty s různými termíny aplikace travního mulče (aplikace po výsadbě a po druhém plečkování) a porovnávány s kontrolní variantou bez mulčování (mechanicky ošetřovanou). Výsledky prokázaly pozitivní vliv travního mulče na výnos konzumních hlíz a některé výnosové prvky porostu brambor. Výnos konzumních hlíz byl v porovnání s nemulčovanou variantou statisticky průkazně vyšší o 9,3 t/ha. Nejvyšší počet konzumních hlíz byl zjištěn u varianty, kde byl travní mulč aplikován po...

Empirical model for quantification of symbiotic nitrogen fixation in grass-clover mixtures
Provedor de dados: 21
Autores: Høgh-Jensen, Henning; Loges, Ralf; Jensen, Erik Steen; Jørgensen, Finn V.; Vinther, Finn P.
Symbiotically fixed nitrogen (N2) is an important input of nitrogen (N) source in many agricultural systems. In spite of this fact, the input of symbiotically fixed N to a particular cropping system is usually not known and exact measurements are costly and laborious. Consequently, there is a demand for an uncomplicated and reliable tool to estimate symbiotic N2 fixation (SNF) in leguminous crops. A simple emperical model is proposed for quantification of SNF in forage legumes under low external input conditions. The model estimates SNF using dry matter yield as input and parameters for (i)N concentration in dry matter and the (ii) proportion of the N in the legume that is derived from the atmosphere. Further, the model includes fixed N not included in the...

Farm Resilience in Organic and Nonorganic Cocoa Farming Systems in Alto Beni, Bolivia
Provedor de dados: 21
Autores: Jacobi, Johanna; Schneider, Monika; Pillco Mariscal, María; Huber, Stephanie; Weidmann, Simon; Bottazzi, Patrick; Rist, Stephan.
Cocoa production in Alto Beni, Bolivia, is a major source of income and is severely affected by climate change impacts and other stress factors. Resilient farming systems are, thus, important for local families. This study compares indicators for social–ecological resilience in 30 organic and 22 nonorganic cocoa farms of Alto Beni. Organic farms had a higher tree and crop diversity, higher yields and incomes, more social connectedness, and participated in more courses on cocoa cultivation. Resilience was enhanced by local farmers’ organizations, providing organic certification and supporting diversified agroforestry with seedlings and extension, going beyond basic organic certification requirements.

Autores: Barzotto, Ionete Lúcia Milani; Alves, Luis Francisco Angeli.
A erva-mate (Ilex paraguariensis St. Hil.) compõe um dos segmentos agroindustriais mais antigos e característicos da região Sul do Brasil, caracterizando-se como uma importante atividade socioeconômica. Para abastecer o mercado consumidor de derivadsupos da erva-mate, foi necessário reflorestar áreas com essa planta, o que simplificou o ecossistema e favoreceu algumas espécies de insetos fitófagos, os quais adquiriram status de praga. Nesse contexto, destaca-se a "ampola" da erva-mate Gyropsylla spegazziniana (Hemiptera: Psyllidae) (Lizer e Treles) pela severidade de danos. Não existem inseticidas registrados para o controle dessa praga no Brasil, e diversos estudos apontam para o manejo populacional da praga. Assim, o objetivo desta revisão é reunir...

Low-P solution culture may assist screening of root growth vigor in soil for high nutrient uptake of spring wheat varieties
Provedor de dados: 21
Autores: Wang, Yaosheng; Andersen, Sven Bode; Thorup-Kristensen, Kristian; Jensen, Lars Stoumann; Magid, Jakob.
Root and root hairs of plants have been intensively studied in solution culture; however, correlation of such measurements in solution culture with development in soil is poorly understood. This study compared growth of roots and root hairs as well as uptake of macro- and micronutrients of six spring wheat varieties in solution culture under P stress and P abundance and in a low fertility soil. Results showed that root length and surface area under P stress was significantly positively correlated with that in the low fertility soil, while no such correlation was apparent for root hair length and density. In absolute terms the root length, surface area, root hair length and density of spring wheat varieties were substantially higher in soil than in solution...

Conservation practices are important in improving the environmental protection of agroecosystems in semiarid regions, as these are considered to be fragile environments. Soil-quality indicators are useful elements in evaluating the impact of some agricultural management practices, and the use of recognized indicators which are able to be measured by farmers is an innovative approach that seeks to integrate both scientific and local knowledge. This study aimed to evaluate the impact of various management practices through indicators of soil quality related to soil structure, in areas of family farming where agroecological consortiums are employed. These indicators were identified as important by the farmers themselves, and methodologies were suggested for...

Tillage as a driver of change in weed communities: a functional perspective
Provedor de dados: 21
Autores: Armengot, L.; Blanco-Moreno, J.M.; Bàrberi, P.; Bocci, G.; Carlesi, S.; Aendekerk, R.; Berner, A.; Celette, F.; Grosse, M.; Huiting, H.; Kranzler, A.; Luik, A.; Mäder, P.; Peigné, J.; Stoll, E.; Delfosse, P.; Sukkel, W.; Surböck, A.; Westaway, S.; Sans, F.X.
The adoption of non-inversion tillage practices has been widely promoted due to their potential benefits in reducing energy consumption and greenhouse emissions as well as improving soil fertility. However, the lack of soil inversion usually increases weed infestations and changes the composition of the weed community. Weed management is still a main drawback for the wider adoption of reduced tillage practices. However, it is not entirely clear whether these changes in weed communities are a consequence of non random filters on the functional attributes of weed species and may thus affect the potential weed-crop competition relationship.  Here, we analyse the changes in weed diversity, community composition, and the functional attributes of weed...

Non-inversion tillage effects on soil mechanical properties of a humid sandy loam
Provedor de dados: 21
Autores: Munkholm, Lars J.; Schjønning, Per; Rasmussen, Karl J.
Optimisation of soil tilth is of paramount importance in organic plant production in order to enhance crop growth. Non-inversion and reduced tillage systems are often claimed to be preferable for organic farming. The purpose of this study was to evaluate the early stage effects of converting a mouldboard-ploughed soil to a non-inversion tillage system. A multi-level experimental strategy including in situ, on-site and laboratory methods was followed in order to relate quantitative measures of soil physical properties directly to soil behaviour in the field. A non-inversion deep soil loosening (0¯35 cm) tillage system (NINV) was compared to a conventional mouldboard ploughing and harrowing tillage system (CONV). The experimental site was located on an...

Transport and reduction of nitrate in clayey till underneath forest and arable land.
Provedor de dados: 21
Autores: Jørgensen, P.R.; Urup, J.; Helstrup, T.; Jensen, M.B.; Eiland, F.; Vinther, F.P.
Transport and reduction of nitrate in a typically macroporous clayey till were examined at variable flow rate and nitrate flux. The experiments were carried out using saturated, large diameter (0.5 m), undisturbed soil columns (LUC), from a forest and nearby agricultural sites. Transport of nitrate was controlled by flow along the macropores (fractures and biopores) in the columns. Nitrate reduction (denitrification) determined under active flow mainly followed first order reactions with half-lives (t1/2) increasing with depth (1.5–3.5 m) from 7 to 35 days at the forest site and 1–7 h at the agricultural site. Nitrate reduction was likely due to microbial degradation of accumulated organic matter coupled with successive consumption of O2 and NO3− in the...

Opportunities to make sequential decisions and adjust activities as a season progresses and more information becomes available characterise the farm management process. In this paper, we present a discrete stochastic two-stage utility efficient programming model of organic dairy farms, which includes risk aversion in the decision maker’s objective function as well as both embedded risk (stochastic programming with recourse) and non-embedded risk (stochastic programming without recourse). Historical farm accountancy data and subjective judgements were combined to assess the nature of the uncertainty that affects the possible consequences of the decisions. The programming model was used within a stochastic dominance framework to examine optimal strategies in...

The past decades have experienced growing demand for ecolabels displaying environmental and sustainability information, with associated price premiums. With growing number of ecolabels in the markets, strategic positioning is required to attract value. Nevertheless, consumer preference for other attributes, for example, local products appears to be overshadowing the value for ecolabels. A suitable communication and education strategy for consumers is warranted to counteract this effect. Using stated choice experiment, we test for the effect of different types of information regarding organic aquaculture production principles on the demand for portion size trout in the German market, while considering other important product attributes. The results indicate...

Integration of organic animal production intor land use with special reference to swine and poultry
Provedor de dados: 21
Autores: Hermansen, John E.; Strudsholm, Karin; Horsted, Klaus.
The development in organic livestock production can be attributed to an increased consumer interest in organic products while, at the same time, increased farmers' interest in converting to organic production methods—often stimulated by governmental support or subsidies. It is important that organic production systems can fulfil the expectations of each of these stakeholders if organic livestock production is to increase further. This is of particular importance if organic pig and poultry production (other than egg) is to move from the present niche-production to a significant place in the food market, as in the case of beef and milk.    It can be argued that the limited organic pork and poultry production is related to the fact that it is far more...

Organic rules for grazing and access to outdoor area in pig production may be met in different ways, which express compromises between considerations for animal welfare, feed self-reliance and negative environmental impact such as greeehouse gas emissions and nitrate pollution. This article compares environmental impact of the main organic pig systems in Denmark. Normally sows are kept in huts on grassland and finishing pigs are being raised in stables with access to an outdoor run. One alternative practised is rearing also the fattening pigs on grassland all year round. The third method investigated was a one-unit pen system mainly consisting of a deep litter area under a climate tent and with restricted access to a grazing area. Using life cycle...

Autores: Jensen, Thomas Secher; Olsen, Kent; Hansen, Tine Sussi; Vedel-Smith, Christina.
During 2008-2011 field voles (Microtus agrestis) were  studied in a Danish agro-ecosystem in connection with a programme elucidating the role of organic farming as refuge for biodiversity, due to the observed biodiversity losses in conventional farmland. The aim of the study was to   quantify home ranges and movements of voles in order to test a hypothesis that vole populations living in organic farm could colonize unoccupied areas in conventional farms. Voles were radiocollared and tracked until death or disappearance. Results showed that vole home-ranges were   larger during onset of the breeding season than during the height of the breeding season and the non-breeding period. Males had larger home ranges than females. Voles occupying isolated small...

Provedor de dados: 21
Autores: Forslund, Anita; Plauborg, Finn; Andersen, Mathias N.; Markussen, Bo; Dalsgaard, Anders.
The risk for contamination of potatoes and groundwater through subsurface drip irrigation with low quality water was explored in 30 large-scale lysimeters containing repacked coarse sand and sandy loam soils. The human pathogens, Salmonella Senftenberg, Campylobacter jejuni and E. coli O157:H7, and the virus indicator Salmonella Typhimurium bacteriophage 28B, were added weekly through irrigation tubes for one month with low irrigation rates (8 mm per week). In the following six months lysimeters were irrigated with groundwater free of pathogens. Two weeks after irrigation was started, phage 28B was detected in low concentrations (2 pfu ml-1) in leachate from both sandy loam soil and coarse sand lysimeters. After 27 days, phage 28B continued to be present...

Nitrogen and sulphur management: challenges for organic sources in temperate agricultural systems
Provedor de dados: 21
Autores: McNiel, A.M.; Eriksen, J.; Bergström, L.; Smith, K.S.; Marstorp, H.; Kirschmann, H.; Nilsson, I.
A current global trend towards intensification or specialization of agricultural enterprises has been accompanied by increasing public awareness of associated environmental consequences. Air and water pollution from losses of nutrients, such as nitrogen (N) and sulphur (S), are a major concern. Governments have initiated extensive regulatory frameworks, including various land use policies, in an attempt to control or reduce the losses. This paper presents an overview of critical input and loss processes affecting N and S for temperate climates, and provides some background to the discussion in subsequent papers evaluating specific farming systems. Management effects on potential gaseous and leaching losses, the lack of synchrony between supply of nutrients...

Increased utilisation of renewable resources: Dilemmas  for organic agriculture
Provedor de dados: 21
Autores: Løes, Anne-Kristin; Adler, Steffen A.
Minimising outputs of waste and pollution by recycling and efficient utilisation of renewable Resources is of common interest for organic agriculture and the concepts of circular and bioeconomy. However, in practice, many efforts  to increase recycling of various biological materials in organic agriculture are hampered because standards for certified organic production and processing tend to prefer  natural products while avoiding processing and especially chemical processes. This creates several dilemmas and weakens the position of organic agriculture as a spear head in the development of better resource utilisation which will reduce environmental impacts from food production. Based on practical examples derived from projects aimed at better utilisation...

From the production of rules to seed production: global intellectual property and local knowledge.
Provedor de dados: 21
Autores: Radomsky, Guilherme Francisco Waterloo; Leal, Ondina Fachel.
This paper analyzes the links and overlappings between traditional knowledge and biodiversity in the context of ecological family farming in southern Brazil. The data presented are part of an ethnographic study carried out among a network of ecological farmers, Ecovida, in the west of Santa Catarina state. The current global patent regime, most prominently the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPs) of the World Trade Organization (WTO), has had direct effects on seed production and agricultural food crops. In a scenario of increasing creation of patents, patent regulations, provisions on cultivars (plant varieties and seed breeding) and a number of other global trade control mechanisms, family farmers and other related...

Slagtesvin på friland kræver optimeret driftsledelse for at mindske miljøbelastningen
Provedor de dados: 21
Autores: Eriksen, J.; Hermansen, J.E.
Ved produktion af svin på friland er det almindeligt at have søerne på græs, mens smågrisene ved fravænning sættes på stald med adgang til et betondækket udeareal. Det kan forekomme paradoksalt at en stor del af det økologiske svinekød stammer fra grise, som hovedparten af deres liv ikke har haft mulighed for naturlig adfærd i form af at rode, grave og græsse.    Når producenterne vælger ikke at have slagtesvin på friland hænger det blandt andet sammen med en række forventede negative effekter, såsom et stort arealkrav, stor arbejdsbelastning, stort foderforbrug og stort tab af næringsstof til omgivelserne. Der kan imidlertid stilles spørgsmål ved om den indendørs produktion af slagtesvin svarer til forbrugernes forventninger om dyrevelfærd i økologiske...

Reduced tillage: Influence on erosion and nutrient losses in a clayey field in southern Finland
Provedor de dados: 21
Autores: Koskiaho, Jari; Kivisaari, Simo; Vermeulen, Stephan; Kauppila, Raimo; Kallio, Kari; Puustinen, Markku.
Reduced tillage was compared with traditional ploughing in terms of erosion and phosphorus (P) and nitrogen (N) losses in an experimental field in southern Finland. One part of the field has been ploughed (treatment PF) and the other part harrowed (treatment NPF) every autumn since 1986. Flow volume and water quality data was collected separately from surface runoff and subsurface drainage waters during 1991-1995 (surface runoff volume since 1993). Erosion was higher in PF (on average 234 kg ha-1yr-1 in drainage flow and 479 kg ha-1 yr-1 in surface runoff) than in NPF (158 kg ha-1yr-1 in drainage flow and 160 kg ha-1yr-1 in surface runoff). Total N loss in drainage flow was also higher in PF (7.2 kg ha-1yr-1) than in NPF (4.6 kg ha-1yr-1). Total P losses...

Phytase activity and degradation of phytic acid during rye bread making
Provedor de dados: 21
Autores: Nielsen, Merete Møller; Damstrup, Marianne Linde; Thomsen, Agnete Dal; Rasmussen, Søren Kjærgaard; Hansen, Åse.
Changes in phytic acid content, activity of phytase and α-amylase in rye breads were determined during rye bread making.    The activity of phytase is highest in grain and flour whereas the activity in the sourdoughs is almost the half of the activity in the flour. The activity was unchanged in the dough after mixing and proofing.     Degradation of phytic acid (IP6) into lower inositol-phosphates and free phosphate is almost completed during the production of rye bread with long fermentation time whereas the degradation is less completed when whole grains are included in the recipe.  In rye bread made from milled rye (DB00), 99% of IP6 is degraded and IP3 becomes the dominating inositol-phosphate in this bread type presumably resulting in a high level of...

Values Based Supply Chains as a Tool for Territorial Development
Provedor de dados: 21
Autores: Stotten, Rike; Schermer, Markus; Pugliese, Patrizia; Lamine, Claire; Bui, Sibylle.
Recently established organic regions aim to be model regions of sustainability. This paper focuses on the role and configurations of values based supply chains for the territorial development of organic regions. Three different case studies of organic regions in Italy, France and Austria are investi-gated. Principles of organic farming according to the International Federation of Organic Agriculture Movement and the concept of neo-endogenous development by Christopher Ray serve as frame-work for analyzes. Finally, we include values-based supply chains into the model of neo-endogenous development: first to link values on a territorial level and second as a tool to imple-ment them.

The role of economic factors in driving conversion to organic farming
Provedor de dados: 21
Autores: Latruffe, Laure; Nauges, Céline; Desjeux, Y.
This article presents the main findings of a recent survey of 307 dairy producers and 99 vegetable producers from Western France. Conventional farmers as well as organic farmers who recently switched to organic farming have been surveyed. Our results illustrate the differences between the two groups of farmers in terms of personal characteristics (age, education level, sensitivity to environmental problems) and in terms of characteristics of their farm (size, labor, soil type). Our findings also show that economic factors are the main drivers of conversion to organic farming in the vegetable sector while ideological factors and, above all, technical factors are most important in the dairy sector.

Replacing grass silage with pea-barley intercrop silage in the feeding of the dairy cow
Provedor de dados: 21
Autores: Pursiainen, Pirjo; Tuori, Mikko.
The effect of replacing wilted grass silage (GS) with pea-barley intercrop silage (PBS) on feed intake, diet digestibility and milk production was studied with 8 multiparous Ayrshire-cows in a replicated 4 × 4 Latin square experiment. Proportion of PBS was 0 (PBS0), 33 (PBS33), 67 (PBS67) or 100 (PBS100) % of silage dry matter (DM). The DM content was 559 and 255 g kg-1 for GS and PBS. Crude protein content was 131 and 170 g kg-1 DM, respectively. Pea-barley silage was more extensively fermented than GS with total fermentation acid content of 120 vs. 12 g kg-1 DM. Silage was fed for ad libitum intake and supplemented with on the average 13 kg concentrate per day. Silage DM intake was 9.2 (PBS0), 9.7 (PBS33), 9.0 (PBS67) and 7.1 (PBS100) kg per day (Pquadr....

AIM: The aim of the present study was to evaluate the diet and biological attributes of the population of Apareiodon affinis residing near net-cage fish farming activities in the Chavantes reservoir.  METHODS: Samples were collected from two populations: one near the net cages (NC) and one from an area not influenced by these cages denominated the "reference site" (RS). Monthly sampling was carried out from Mar/2008 to Feb/2009. Fish were caught with a standardized effort using gill nets deployed for 14 hours. After all individuals were measured (standard length) and weighed (total weight, carcass weight , body weight without gonads). To determine the composition of the diet, the alimentary index was calculated (AI). We also calculated the length-weight...

Quantitative proteomics by 2DE and MALDI MS/MS uncover the effects of organic and conventional cropping methods on vegetable products
Provedor de dados: 21
Autores: NAWROCKI, Arkadiusz; Thorup-Kristensen, Kristian; Jensen, Ole Nørgaard.
Organic farming aims to be environmentally sound, but the question as to whether organic cropping brings more nutritional benefits to farmers and consumers than the conventional cropping needs still to be answered. To gain insights into the molecular effects of organic farming we used proteome analysis to analyze cabbage (Brassica oleracea L. var ‘capitata’) and carrot (Daucus carota var. ‘sativus’) Our aim was to identify the metabolic pathways that are affected by different cropping regimes and thus, may have an effect on quality, storability and pathogen resistance of crops. By means of two dimensional gel electrophoresis and MALDI tandem mass spectrometry we compared proteomes of cabbage and carrot root, obtained in the first growth season, cropped...

Plant communities of field boundaries in Finnish farmland
Provedor de dados: 21
Autores: Tarmi, Sanna; Tuuri, Hannu; Helenius, Juha.
To determine the importance of field boundary habitats for farmland biodiversity, we surveyed a total of 193 boundaries from four climatically and agriculturally dissimilar regions in Finland. We measured the current plant species richness and composition of the boundaries, and based on the differences in vegetation characteristics, we describe six boundary types. The observed plant species were mainly indicators of fresh to wet soils and moderate to rich mineral nitrogen content. The most frequent species were tall, perennial monocots and dicots indicating the high productivity of thevegetation. Moreove, herbicide-tolerant species were common. No species rare for Finland were found.In animal husbandry regions, the most frequent species were sown grassland...

Autores: Molkentin, Joachim.
The validity of established threshold values for the analytical authentication (stable isotopes and fatty acids) of organic drinking milk in Germany was determined for more strongly processed organic dairy products (n = 56). Milk fat extracted from both soft and semi-hard cheeses, butter, cream, sour cream, buttermilk, yoghurt and low-fat milk always possessed an alpha-linolenic acid (C18:3w3) content above the minimum level of 0.50% and a stable isotope ratio of carbon (delta13C) below the maximum level of -26.5‰ required for organic milk. Noncompliant results were obtained for whey as well as both Italian ice creams and cheeses. Analyses of German cream cheese and curd lipids revealed that 7 out of 39 samples did not comply with the two thresholds. An...

We explored the value of ergosterol, phospholipid fatty acid (PLFA) profiles and neutral lipid fatty acid (NLFA) 16:15c as soil quality indicators for the intensive systems of vegetable production in the humid tropical climate of West Java, by comparing organic and conventional management. Additionally, we measured dehydrogenase and -glucosidase activity. A secondary forest was included to obtain reference values under undisturbed conditions. Organic and conventional agriculture, and secondary forest each differed in the composition of the microbial community measured by PLFA profiles. Ergosterol appeared not to be universally applicable as a fungal biomarker and in this respect seemed to be inferior compared to PLFA fungal markers. NLFA 16:15c may...

Crop, weeds and arthropods were sampled in conventionally and organically cultivated spring- and winter-sown cereal fields. Weed biomass was much higher in organically cultivated fields, while arthropod biomass hardly showed any differences. Results from very weedy areas of organically grown fields indicate that a more extensive management allowing even more weeds may be favourable to insects and the animals feeding on them.

O presente estudo é uma revisão sobre a contribuição da agroecologia para o debate conservacionista e desenvolvimentista. O discurso tradicional da biologia da conservação traz um enfoque exclusivo nas unidades de conservação (UCs), prejudicando os esforços de preservação da matriz paisagística como todo. Por outro lado, o discurso pautado por alguns desenvolvimentistas é levado por uma diferente, mas não menos equivocada, corrente de pensamento que acredita na superioridade da produção agrícola intensiva frente à agricultura familiar. No Brasil, essa modernização precoce da agricultura teve consequências catastróficas para o pequeno produtor bem como levou o aumento da pobreza no campo e nas cidades.

Performance of spring barley varieties and variety mixtures as affected by manure application and their order in an organic crop rotation
Provedor de dados: 21
Autores: Askegaard, M.; Thomsen, I.K.; Berntsen, J.; Hovmøller, M.S.; Kristensen, K.
In order to obtain a high and stable yield of organic spring barley, production should be optimized according to the specific environment. To test the performance of spring barley varieties under varying cropping conditions, a field experiment was carried out in 2003 and 2004 in a six-field mixed organic crop rotation. We investigated the choice of variety, the order in a rotation,and the application of manure (slurry and farm yard manure; 0 to 120 total-Nha�1) on grain yields of six selected varieties with different characteristics grown in either pure stands or in two spring barley mixtures, each consisting of three varieties.     Average grain yield of the barley varieties varied between 3.3 t DM ha-�1 and 4.1 t DM ha-�1. Grain yields of the two...

Environmental impact of grazed grass/clover patures
Provedor de dados: 21
Autores: Ledgard, S.; Schils, R.; Eriksen, J.; Luo, J.
Grazed clover/grass pastures are important for animal production systems and the clover component is critical for its contribution to nitrogen (N) inputs via biological fixation of atmospheric N2.  The resource efficiency and environmental emissions for clover/grass pastures can differ from that of N-fertilised grass-only pastures.  Clover N2 fixation uses photosynthetically-fixed carbon, whereas N fertiliser production consumes fossil fuels and has net greenhouse gas (GHG) emissions. Clover has a higher phosphorus (P) requirement than grass and where extra P fertiliser is used for clover/grass pastures the risk of P loss to waterways is greater than for grass-only pastures.  Nitrogen leaching from grazed pasture increases exponentially with increased N...

Elicitors and soil management to induce resistance against fungal plant diseases
Provedor de dados: 21
Autores: Tamm, L.; Thürig, B.; Fließbach, A.; Goltlieb, A. E.; Karavani, S.; Cohen, Y.
Air-borne foliar diseases as well as soil-borne diseases can cause substantial losses in agricultural production systems. One of the strategies to overcome production losses caused by plant diseases is the targeted use of disease defence mechanisms that are inherent to plants. In this paper, the potential to enhance the plant’s health status either by inducing resistance through optimized soil management techniques or by foliar application of inducers of resistance is explored on the basis of a literature review and results from laboratory and field experiments. In our studies, the focus was on recent research about the use of dl-ß-aminobutyric acid (BABA) and an aqueous extract of Penicillium chrysogenum (Pen) as elicitors. We conclude that BABA as well...

Arzneipflanzen im Berner Pferdestall: Erfahrungswissen  von Pferdehaltern
Provedor de dados: 21
Autores: Ryhner, Thea; Meier, Beat; Walkenhorst, Michael.
Hintergrund: Während über den traditionellen Einsatz von Arzneipflanzen durch Landwirtinnen und Landwirte beim Nutztier sowohl in Südeuropa als auch in der Schweiz zunehmend wissenschaftliche Veröffentlichungen vorliegen, fehlen gezielte Studien mit Pferdebesitzern weitestgehend. Mit der vorliegenden Studie sollte dieses Wissen exemplarisch für den Schweizer Kanton Bern erfasst werden. Probanden und Methoden: Methodisch an vorhergehende Studien in der Schweiz angelehnt, wurden von 2011-2012 7 Pferdehalter im Alter von 24-65 Jahren anhand eines semistrukturierten Fragebogens zum Einsatz von Arzneipflanzen bei ihren Pferden interviewt. Neben Informationen zu Pflanzenarten und Pflanzenteilen wurden die Zubereitung und Anwendung (inklusive Dosierung) der...

Ecological selectivity of pesticides and application methods.
Provedor de dados: 21
Autores: Collier, Rosemary; Jukes, Andrew; Daniel, Claudia; Hommes, Martin.
Abstract: There has been a lot of emphasis over the years on the development and use of pesticides that are specific and/or physiologically selective. This is a property of the chemistry and mode of action of the pesticide and the physiological and biochemical attributes of organisms. However, there is also the potential to make pesticides more selective through their judicious use, based on critical selection, timing, dosage, placement and formulation of pesticides (which are often broad spectrum). This paper discusses approaches to increase the ecological selectivity of pesticides and pesticide application methods, in the context of Integrated Pest Management in Brassica crops. Topics covered include minimisation of the dose applied, controlled release...

Blé biologique suisse: Qualité bonne mais variable
Provedor de dados: 21
Autores: Dierauer, Hansueli; Kupferschmid, Cornelia.
La qualité du blé biologique suisse est bonne, dit-on, mais les centres collecteurs continuent de recevoir régulièrement des lots dont la qualité ne correspond pas aux normes exigées. Bio Suisse voulait savoir à quoi en est réellement la qualité du blé biologique suisse et s’il y a besoin de prendre des mesures. Elle a donc lancé en 2009 avec le FiBL un projet national de recensement et si nécessaire d’amélioration de la qualité du blé. Les résultats de cette étude de trois ans sont maintenant connus.

Förderung von Wildbienen in Heidelbeerkulturanlagen
Provedor de dados: 21
Autores: Boecking, Otto; Kubersky, Ulrike.
In der heutigen Zeit ist Bestäubung nicht immer garantiert. Die Vielfalt an Bienen ist während der letzten Jahre signifikant zurückgegangen. Die Anstrengungen zum Erhalt der Blütenbestäuber müssen fortgeführt werden. Dies gilt insbesondere für diejenigen, die direkte Nutznießer der Bestäuber in landwirtschaftlichen Kulturen sind. Wildbienen-Bestäubervielfalt ist nachweislich von Nutzen für Ertragssteigerungen im Kulturheidelbeeranbau. Dies gilt insbesondere für diverse Hummelarten. Wer von Wildbienen als natürliche Bestäuber mit höheren Erträgen profitieren will, muss ihnen mehr bieten, als nur das Blühangebot der Kulturpflanze (Heidelbeere). Landschaftsgestaltung zur Förderung der Bestäuber wird also Teil des Bestäuber-Managements. Gemeinsam mit den...

Instant infusion pasteurisation of bovine milk. I. Effects on bacterial inactivation and physical-chemical properties.
Provedor de dados: 21
Autores: Hougaard, A.B.; Hammershøj, Marianne; Vestergaard, Jannie S.; Poulsen, Ole; Ipsen, R.
Two types of milk, skim milk and non-standardized raw milk, were heat treated using direct heating by instant infusion pasteurization with treatment temperatures in the range from 72°C to 120°C and with holding times of less than 1 second. Indirect heating by HTST pasteurization (72°C for 15 seconds) was used for comparison. The inactivation of microorganisms reached at least the same level when using instant infusion pasteurization compared to HTST pasteurization. Changes in the physical-chemical properties were observed in the skim milk fractions of instant infusion pasteurized non-standardized milk, whereas for instant infusion pasteurized skim milk less influence from the treatments was observed.

Relations between Agronomic Practice and Earthworms in Norwegian Arable Soils
Provedor de dados: 21
Autores: Pommeresche, Reidun; Løes, Anne-Kristin.
This paper presents Norwegian studies of earthworms (density, biomass, burrows density, species, juvenile to adult ratios) in arable soil in Norway conducted during the last 20 years. The effects of crop rotations, fertilization, soil tillage and compaction on earthworms are presented, based on various field experiments. Geophagous (soil eating) species such as Aporrectodea caliginosa and A. rosea dominate the earthworm fauna in Norwegian arable soil. Lumbricus terrestris is also present; in our studies even frequently found in an all-arable crop rotation with annual ploughing. In southern Norway, L. rubellus, and A. longa are commonly found. Earthworm density, recorded in autumn varied between 30 and 350 individuals m-2 in different studies, with the...

Cultivar and Year-to-Year Variation of Phytosterol Content in Rye (Secale cereale L.)
Provedor de dados: 21
Autores: Zangenberg, M.; Hansen, H.B.; Jørgensen, J.R.; Hellgren, L.I.
Intake of phytosterols (and -stanols) has been shown to decrease the level of low-density lipoprotein cholesterol and thus protect against development of cardiovascular diseases. Therefore, studies on the cultivar and year-to-year variation in phytosterol content in rye grains have been performed. The phytosterol content and composition of different rye cultivars, grown under identical conditions on the same field in three consecutive years, were analyzed. Both cultivar and year-to-year variation in sterol content were statistically significant (p &lt; 0.0001). The total sterol content varied from 1007 ± 21 mg/kg in the highest yielding cultivar, Tsulpan 3, to 761 ± 10 mg/kg in the lowest yielding cultivar (Amando in the 1999 harvest). Because the...

Consumers’ evaluation of imported organic food products: The role of geographical distance
Provedor de dados: 21
Autores: Pedersen, Susanne; Aschemann-Witzel, Jessica; Thøgersen, John.
Country-of-origin (COO) effects and consumer evaluation of organic food products are rarely studied in combination. The aim of this study was therefore to investigate organic consumers’ preferences for imported organic food products from different origins and the underlying reasons for these preferences, including how consumers’ COO preferences depend on the geographical distance to the COO. We employed a multi-method, qualitative approach consisting of in-store interviews (N = 255) and focus groups (six, N = 38) with organic consumers in three German cities located in the north (Hamburg, close to Denmark), west (Münster, close to The Netherlands) and south (Munich, close to Austria). The interviews confirmed the well-known preference for domestic (also...

Krankheitstoleranz und Geschmack im Test: Welche Karottensorten bewähren sich im Bioandbau
Provedor de dados: 21
Autores: Koller, Martin; Vieweger, Anja.
Im Bio-Karottenanbau ist neben einem guten Ertrag auch die Krankheitstoleranz gegenüber Blattalternaria sehr wichtig. Weitere wichtige Sorteneigenschaften sind eine regelmäßige Kalibrierung und ein guter Geschmack. Bei vielen neuen Sorten werben die Saatgutproduzenten speziell mit einer «guten Alternariatoleranz » oder mit «gesundem Laub». Das FiBL hat 2002 auf zwei Betrieben in Basadingen TG und Kölliken AG Sortenversuche durchgeführt. Sechs Sorten wurden auf Ertrag, Alternariatoleranz, Zuckergehalt und Geschmack untersucht.

Advantages of low input livestock production on large pastures, including animal welfare, biodiversity and low  production costs are challenged by losses due to undetected disease, accidents and predation. Precision livestock  farming (PLF) enables remote monitoring on individual level with potential for predictive warning. Body temperature  (Tb) and heart rate (HR) could be used for early detection of diseases, stress or death. We tested  physiological sensors in free-grazing Norwegian white sheep in Norway. Forty Tb sensors and thirty HR sensors  were surgically implanted in 40 lambs and 10 ewes. Eight (27%) of the HR and eight (20%) of the Tb sensors  were lost during the study period. Two Tb sensors migrated from the abdominal cavity in to the...

Is organic farming inefficient, or are indicators of economic performance of agriculture incomplete?
Provedor de dados: 21
Autores: Huhtala, Anni.
Organic farming is expected to alleviate the environmental burden of agriculture, since it rules out the use of chemicals such as synthetic fertilizers, pesticides, herbicides. However, organic farming technology may turn out to be less efficient when evaluated by conventional productivity measures that are less informative regarding environmental efficiency. We derive a framework for a combination of more comprehensive indicators reflecting whether organic farming increases sustainability in agriculture and how much of the total agricultural value added is produced at the expense of environmental deterioration. We show that it is important to separate flow and stock effects of pollution so that aggregate measurement is consistent with conventional...

Provedor de dados: 21
Autores: Li, Xiaoqiong; Jensen, Rikke Lassen; Højberg , Ole; Canibe, Nuria; Jensen, Bent Borg.
Strain SK9K4T, a strictly anaerobic, non-motile, non-sporulating, Gram-positive, saccharolytic coccobacillus was isolated from pig feces. SK9K4T metabolized indol-3-acetic acid to 3-methylindole (skatole), which is the main contributor to boar taint and also produced 4-methylphenol (p-cresol) from p-hydroxyphenylacetic acid. Phylogenetic analyses based on 16S rRNA gene sequences revealed that the isolate represented a new lineage within the genus Olsenella of the family Atopobiaceae. Strain SK9K4T was most closely related to the type strains of the three recognized Olsenella species; Olsenella profusa DSM 13989T (93.6%), Olsenella uli DSM 7084T (93.5%) and Olsenella umbonata DSM 22620T (92.7%).

Organic farming has been proposed as a solution to foster agricultural sustainability and mitigate the negative environmental impacts of conventional farming. This study assessed N losses and soil surface N balances in conventional and organic farming systems in a sub-humid and semi-humid (Chuka and Thika) sites in Kenya. Nitrate–N (NO3−–N) leached was trapped at 1 m depth using the Self Integrating Accumulator core method and the changes in mineral-N were assessed at different soil depths and different crop growth stages. Both conventional and organic farming systems lost substantial amounts of NO3−–N at the early growth stages of all the crops. Cumulative NO3−–N leached was similar in all the farming systems in each cropping season. More NO3−–N was...

Microbially-mediated P fluxes in calcareous soils as a function of water-extractable phosphate
Provedor de dados: 21
Autores: Schneider, Kimberly D.; Voroney, R. Paul; Lynch, Derek H.; Oberson, Astrid; Frossard, Emmanuel; Bünemann, Else K.
Soil phosphorus (P) tests are designed to indicate plant-available inorganic orthophosphate (Pi), but fail to account for Pi that may become available through organic phosphorus (Po) mineralization. This P source may be especially important in soils with low concentrations of solution and labile Pi. We assessed gross Po mineralization and immobilization using labeling with 33P in four calcareous Alfisols with varying concentrations of Olsen soil test P that were collected from forage fields of dairy farms in Ontario, Canada. Rapid microbial 33P uptake during incubation was found for the soils with the lowest available Pi as indicated by both Olsen soil test P and water-extractable Pi. The tracer incorporation into microbial P after 8 days ranged from 7 to...

Soil Fertility and Biodiversity in Organic Farming
Provedor de dados: 21
Autores: Mäder, Paul; Fliessbach, Andreas; Dubois, David; Gunst, Lucie; Fried, Padrout; Niggli, Urs.
An understanding of agroecosystems is key to determining effective farming systems. Here we report results from a 21-year study of agronomic and ecological performance of biodynamic, bioorganic, and conventional farming systems in Central Europe. We found crop yields to be 20% lower in the organic systems, although input of fertilizer and energy was reduced by 34 to 53% and pesticide input by 97%. Enhanced soil fertility and higher biodiversity found in organic plots may render these systems less dependent on external inputs.

The purpose of this article is to critically explore the widely shared assumption that trust is vital for supporting future growth of organic farming. Based on selected results of three recent research projects, the contribution investigates the concept of trust, and the relation between trust and organics in a management and in a media research perspective. Our conclusion is that neither management nor media research support the assumed direct importance of trust in organic certification logos for organic growth. The article proposes the development of interdisciplinary and contextualized understandings of trust as avenue for further research.

Organic farmers are interested in adopting conservation tillage to preserve soil quality and fertility and to prevent soil erosion. Within the framework of a French national study, we compared conventional (ploughing) and conservation tillage systems in organic farming for arable and vegetable cropping systems. Field experiments and on-farm surveys were conducted in several regions of France in order to assess the effects of different tillage systems on soil fertility (physical, chemical, biological) and on weed and crop development. Conservation tillage techniques induced a more compact soil, an increase of carbon and microorganisms in the first soil layer, and an increase of earthworm biomass for very superficial tillage. Weed control was only a major...

Estado e agricultores familiares: uma análise interpretativa sobre o desenvolvimento rural no Sul de Minas Gerais.
Provedor de dados: 21
Autores: Ferreira, Patrícia Aparecida; Pereira, José Roberto; Alencar, Edgard; Santana, Ana Carolina.
Este trabalho procurou identificar como os atores sociais vinculados à agricultura familiar (lideranças de produtores familiares, profissionais de ciências agrárias, autoridades municipais, pesquisadores e professores universitários) interpretam o papel do Estado para o desenvolvimento dessa categoria na região sul de Minas Gerais. Com relação à coleta de dados, utilizou-se a técnica "focused interview". Os entrevistados foram seledonados pelo método não-probabilístico de amostragem por julgamento. Os resultados revelaram que a interpretação feita pelos entrevistados aproxima-se mais da perspectiva do Estado patrimonialistaburocrático autoritário, tendo em vista que os depoimentos dos entrevistados corroboram com a reprodução das relações de dependência...

The pros and cons of sodium percarbonate
Provedor de dados: 21
Autores: Pedersen, Lars-Flemming; Jokumsen, Alfred.
The article deals with the use an approved aquaculture sanitizer: sodium-percarbonate (SPC).The substance is an easy to use powder containing hydrogen peroxide; when added to fish ponds hydrogen peroxide gets dissolved and subsequently decomposed into oxygen and water. This article presents the results from measurements in January 2017 in connection with practical application at an organic fish. The study showed that SPC leads to an evenly distribution of hydrogen peroxide in the water and maintained for a few hours. The water treatment causes oxygen liberation at the same time but also a significant pH increase which has to be taken into account for optimal management.

Drying behavior and quality parameters of dried beef (biltong) subjected to different pre-treatments and maturation stages
Provedor de dados: 21
Autores: von Gersdorff, Gardis J.E.; Porley, Victoria E.; Retz, Stefanie K.; Hensel, Oliver; Crichton, Stuart.O.J.; Sturm, Barbara.
The drying behavior of fresh, matured, and frozen beef, marinated with 0.5% salt, 1% salt, salt and vinegar, and blind samples, dried at 70°C, was investigated. Weight and color (CIELAB) were measured and images of the samples were created with a hyperspectral imaging camera. Results show that the marinade and the type of beef influences the drying behavior of beef, but not the final color. Results from the hyperspectral imaging show that it is possible to build good fitting prediction models resulting in high R2 (min. 0.81, max. 0.98) and low RMSE (min. 0.08, max. 2.35) for moisture content, a* and b* values.

Effect of three farming systems (bio-dynamic, bio-organic, conventional) on yield and quality of beetroot (Beta vulgaris L. var. esculenta L.) in a seven year crop rotation
Provedor de dados: 21
Autores: Mäder, P.; Pfiffner, L.; Niggli, U.; Balzer, U.; Balzer, F.; Plochberger, A.; Velimirov, A.; Besson, J.-M.
In a long-term field trial in Therwil, Switzerland, the bio-dynamic, bio-organic and conventional farming systems were compared (DOC trial). The present paper focuses on long-term yield development and on product quality of beetroot. Due to the favourable climate and soil, beetroot yields were generally high. The yield of beetroot in both biological systems was about 75 % that of the conventional system, but the input of nitrogen and potassium was about 60 % lower.

Autores: Bach, Vibe; Kidmose, Ulla; Kristensen, Hanne Lakkenborg; Edelenbos, Merete.
The eating quality of carrots (Daucus carota L.) was investigated to evaluate the impact of cropping systems (one conventional and three organic systems) and growing years (2007, 2008, and 2009) on root size, chemical composition, and sensory quality. The content of dry matter, sugars, polyacetylenes, and terpenes as well as the sensory quality and root size were related to the climate during the three growing years. A higher global radiation and a higher temperature sum in 2009 as compared to 2007 and 2008 resulted in larger roots, higher contents of dry matter, sucrose, total sugars, and total polyacetylenes, and lower contents of terpenes, fructose, and glucose. No differences were found between conventional and organic carrots with regard to the...

Comparison of the environmental performance of different treatment scenarios for the main phosphorus recycling sources
Provedor de dados: 21
Autores: Hörtenhuber, Stefan Josef; Theurl, Michaela Clarissa; Möller, Kurt.
Efficient phosphorus (P) recycling from rural and urban areas is becoming an increasing issue due to the scarcity of natural P deposits. Based on a life cycle assessment (LCA), we analyzed the environmental performance of 17 different P supply and recycling approaches from urban wastes, biosolids and slaughterhouse wastes compared with the two conventional inorganic fertilizers phosphate rock and triple superphosphate. The results show that many recycled P fertilizers (RPFs; e.g., digestates from urban organic wastes, biosolids and their ashes, meat and bone meal (MBM) and its recycling products) are competitive in terms of LCA results compared with conventional P fertilizers. For each of the P recycling sources, one or more treatment options were...

Diversity and spatial and temporal variation of benthic  macroinvertebrates with respect to the trophic state of Lake Figueira in the South of Brazil.
Provedor de dados: 21
Autores: Lima, Fernanda Blauth de; Schäfer, Alois Edward; Lanzer, Rosane Maria.
Benthic macroinvertebrates are widely used in evaluations of environmental impact and recommended in biomonitoring, but little used in Brazilian lentic environments. One of the main objectives has been to explain and predict the distribution of those species according to environmental characteristics. Thus, the study aims to characterize the predominant fauna of the Lake Figueira sediment and its relationship with organic matter and depth, analyzing seasonal variation in communities and aiming to select bioindicators of the trophic state. Sampling was carried out from January 2008 to January 2009, along the lagoon fetch, with an Ekmann-Birge dredge (area 225 cm2). Taxon richness was not significantly related with depth and organic matter content, but those...

Phosphorus mobilization in low-P arable soils may involve soil organic C depletion
Provedor de dados: 21
Autores: Romanyà, Joan; Blanco-Moreno, José Manuel; Sans, F. Xavier.
Organic farming systems often show negative nutrient balances that may compromise the availability of phosphorus over the mid-term. Calcareous soils with low organic matter generally show low or very low phosphorus availability. Under these conditions, P retained in soil organo-mineral complexes -either in organic or inorganic forms-after its solubilization and -in the case of organic P compounds-subsequent mineralization may be a source of P to plants and soil organisms. By studying the changes in soil retained and soluble P pooloccurring during the growth of two legumes in two scenarios of contrasting P availability we aimed to describe the release of soil retained P, organic and inorganic, into the soluble pools and to relate it to changes in organic C...

Repeated Applications of a Nonpathogenic Streptomyces Strain Enhance Development of Suppressiveness to Potato Common Scab
Provedor de dados: 21
Autores: Hiltunen, L H; Kelloniemi, J; Valkonen, J P T.
Potato scab caused by several Streptomyces spp. is an important disease with no effective methods of control. Suppressiveness against common scab can develop in soil as a result of long-term monoculture and has been associated with nonpathogenic Streptomyces spp. To determine whether the development of scab suppressiveness could be enhanced, the effect of repeated antagonist Streptomyces strain on common scab was investigated in a long-term field trial over 5 years. Streptomyces strain 272 applied annually at planting consistently suppressed development of common scab symptoms. On scab-susceptible potato cultivar Bintje, strain 272 reduced disease severity, on average, by 43 %; whereas, on the scab-tolerant Nicola, the strain reduced both disease incidence...

Field studies have revealed the impact of changing water regimes on the structure of arbuscular mycorrhizal fungal (AMF) communities, but it is not known what happens to the abundance of individual AMF species within the community when the water conditions in the rhizosphere change. The behavior of four AMF species isolated from the Arabian desert (Diversispora aurantia, Diversispora omaniana, Septoglomus africanum, and an undescribed Paraglomus species) was investigated when assembled in microcosms containing Sorghum bicolor as host plant, and treated with various water regimes. Furthermore, the impact of invasion of these assemblages by Rhizophagus irregularis, an AMF species widely used in commercial inocula, was studied. The abundance of each AMF...

The Contribution of Organic Livestock to Sustainable Rural Development in Sensitive Areas
Provedor de dados: 21
Autores: Escribano, AJ; Gaspar , P; Mesias, FJ; Escribano, M.
Organic production may contribute positively to rural development. However, there is a gap of knowledge with regard to the livestock sector that the present work is aimed at filling by means of a multidisciplinary and participatory approach. The results suggest that ‘fully organic’ holdings (organic farms that sell products as organic) have the highest potential to contribute to the rural development in the area under study. Nevertheless, its implementation requires higher levels of education and implies higher costs. Due to these difficulties, public subsidies should support such production systems. Moreover, systems with low productivity but high environmental services should be also supported, such as those extensive (either conventional or organic).

Mechanical properties of oats and oat products
Provedor de dados: 21
Autores: Gates, Fred K.; Dobraszczyk, Bogdan J.
The aim of this review is to illustrate how physical properties are important to food processing and quality. Three food products, flakes, porridge and bread, in addition to oat groats are used to show the influence of water and heat-treatments on the mechanical properties. The hydrothermal history of ingredients is shown to affect product quality. Water acts as a plasticiser and solvent in these foods, whilst heat modifies the conformation and interactions of macromolecular components. Structure as well as chemical composition is shown to govern texture.

Survey of organochlorine pesticides in horticultural soils and there grown Cucurbitaceae
Provedor de dados: 21
Autores: Hilber, Isabel; Mäder, Paul; Schulin, Rainer; Wyss, Gabriela S.
Organochlorine pesticides (OCP) are still found in food and feed crops although they were applied about 40 years ago. There is a considerable knowledge gap concerning the extent of soil and crop contamination by OCP. We performed two surveys in 2002 and 2005 to assess the loads of OCP in 41 Swiss horticultural fields under organic and conventional production and corresponding Cucurbitaceae fruits (cucumbers, zucchini, and pumpkin), whereas these fields stay for intensive agricultural production in Europe. In addition, soil organic carbon, texture, and pH were measured also. OCP were detected in 27 out of 41 fields (65.9%). The farming practice had no influence on the contamination or level of OCP in soil. The sum of OCP-loads per field ranged from &lt;0.01...

Regulation of cytochrome P450 mRNA expression in primary porcine hepatocytes by selected secondary plant metabolites from chicory (Cichorium intybus L.)
Provedor de dados: 21
Autores: Rasmussen, Martin Krøyer; Klausen, Christina Lindgaard; Ekstrand, Bo.
Chicory (Cichorium intybus) has been shown to induce enzymes of pharmacokinetic relevance (cytochrome P450; CYP). The aim of this study was to investigate the effects of selected secondary plant metabolites with a global extract of chicory root, on the expression of hepatic CYP mRNA (1A2, 2A19, 2C33, 2D25, 2E1 and 3A29), using primary porcine hepatocytes. Of the tested secondary plant metabolites, artemisinin, scoparone, lactucin and esculetin all induced increased expression of specific CYPs, while esculin showed no effect. In contrast, a global extract of chicory root decreased the expression of CYP1A2, 2C33, 2D25 and 3A29 at high concentrations. The results suggest that purified secondary metabolites from chicory affect CYP expression and thereby might...

Phytotherapy in zoo animals
Provedor de dados: 21
Autores: Hoby, S.; Wenker, C.; Walkenhorst, M.
Phytotherapy is one of the oldest medical disciplines and was traditionally based on empiricism (Reichling et al., 2008). Nowadays, its use as an additional integral component of evidence based medicine is well accepted in human medicine (Finkelmann, 2009). Herbal remedies are generally characterised by a broad therapeutic index. They consist of multicomponent mixtures and act as multi-target drugs with pleiotropic effects. In Switzerland, veterinary phytotherapy has been relaunched in 2006 as a subunit of the Swiss Medical Society for Phytotherapy (SMGP-vet). Since 2012, the certificate of qualification in veterinary phytotherapy has been approved by the Swiss Veterinary Association (GST/SVS). Historically, one of the common approaches to gain insight...

Ovarian Activity and Oestrous Signs among Group-Housed, Lactating Sows: Influence of Behaviour, Environment and Production
Provedor de dados: 21
Autores: Hultén, Fredrik; Wallenbeck, Anna; Rydhmer, Lotta.
Animal welfare concerns require the development of housing systems that allow the animals to express their natural behaviour. One example of this is the group-housing system for lactating sows. The present study aimed at exploring ovarian activity in such a system. Thirty-eight sows farrowing individually outdoors during spring and summer, and indoors during autumn and winter, and group-housed in groups of four during weeks 3–7 of the lactation period, were monitored regarding reproductive functions, behaviour and production during their first to fourth lactation period. Average ovulation frequency during lactation was 47%. Only 50% of these ovulating cases were accompanied by a standing oestrus. Lactational ovulation frequency was higher in later parities...

Leys with high plant biodiversity as feed resources for pollinators
Provedor de dados: 21
Autores: Søegaard, K.; Eriksen, J.; Strandberg, B.; Dupont, Y.
Multispecies leys contain different ecosystem services, and feed resources for pollinators can possibly be one. The challenge is to construct grassland with different flowering species and with a continuous flowering without compromising yield and herbage quality. A field experiment was carried out to examine the effect of cutting strategy in different designed species mixtures on yield, herbage quality and flowering. Two main types of mixtures were examined. High productive grass/clover mixtures with chicory, ribwort plantain or caraway and lower productive two species mixtures with weak competitors, salad burnet or dandelion, together with either birdsfoot trefoil, red clover or lucerne. The annual dry matter yield was not affected by the cutting...

Accumulation and translocation of sparingly soluble manure phosphorus in different types of soils after long-term excessive inputs
Provedor de dados: 21
Autores: Uustitalo, Risto; Ylivainio, Kari; Turtola, Eila; Kangas, Arjo.
When phosphorus (P) is applied to soils in excess of plant P demand, P accumulation takes place. By means of P fractionation, we studied the fate of P in 35 soils that had received long-term surplus P rates as fox and mink manure P (F&amp;MM-P), considered as a sparingly soluble P source. We compared these data with those from the same soils under a more typical P management, i.e., fields amended with soluble P sources superphosphate and dairy manure (SP+DM). Fractionation of manures according to the Hedley procedure suggested limited solubility of F&amp;MM-P, two-thirds of the F&amp;MM-P being soluble in acid (HCl) only. In mineral soils, surplus F&amp;MM-P accumulated for the most part as HCl-P (poorly available), whereas in organic soils accumulation...

A participatory approach to design monitoring indicators of production diseases in organic dairy farms
Provedor de dados: 21
Autores: Duval, Julie; Fourichon, Christine; Madouasse, Aurélien; Sjöström, K.; Emanuelson, Ulf; Bareille, Nathalie.
Production diseases have an important negative effect on the health and welfare of dairy cows. Although organic animal production systems aim for high animal health levels, compliance with European organic farming regulations does not guarantee that this is achieved. Herd health and production management (HHPM) programs aim at optimizing herd health by preventing disease and production problems, but as yet they have not been consistently implemented by farmers. We hypothesize that one reason is the mismatch between what scientists propose as indicators for herd health monitoring and what farmers would like to use. Herd health monitoring is a key element in HHPM programs as it permits a regular assessment of the functioning of the different components of...

Autores: Carrasco, Lucía; Gattinger, Andreas; Fließbach, Andreas; Roldán, Antonio; Schloter, Michael; Caravaca, Fuensanta.
The objective of this study was to compare the microbial community composition and biomass associated with the rhizosphere of a perennial gramineous species (Lygeum spartum L.) with that of an annual (Piptatherum miliaceum L.), both growing in semiarid mine tailings. We also established their relationship with the contents of potentially toxic metals as well as with indicators of soil quality. The total phospholipid fatty acid (PLFA) amount was significantly higher in the rhizosphere soil of the annual species than in the rhizosphere soil of the perennial species. The fungal/bacterial PLFA ratio was significantly greater in the perennial species compared to the annual species. The fatty acid 16:1ω5c, the fungal/bacterial PLFA ratio and...

Agricultural intensification is a leading cause of global biodiversity loss, which can reduce the provisioning of ecosystem services in managed ecosystems. Organic farming and plant diversification are farm management schemes that may mitigate potential ecological harm by increasing species richness and boosting related ecosystem services to agroecosystems. What remains unclear is the extent to which farm management schemes affect biodiversity components other than species richness, and whether impacts differ across spatial scales and landscape contexts. Using a global metadataset, we quantified the effects of organic farming and plant diversification on abundance, local diversity (communities within fields), and regional diversity (communities across...

In Organic Agriculture, cultivation environments and agronomic practices are very diverse. This diversity can be handled with decentralized selection based on the knowledge of farmers and scientists. A collaborative work between associations from Réseau Semences Paysannes and the DEAP team from INRA du Moulon set up an innovative breeding approach on farm based on decentralization and participation of farmers.  This approach makes it possible to (i) create new population varieties of bread wheat locally adapted (genetic innovation) (ii) set up an organizational scheme based on decentralization and co construction between actors (societal innovation) and (iii) develop experimental designs, create statistical and data management tools which stimulate these...

Autores: Stadtlander, T.; Khalil, W.K.; Levavi-Sivan, B.; Kerem, Z.; Dweik, H.; Qutob, M.; Abu-Lafi, S.; Focken, U.; Becker, K.
Saponins are generally regarded as anti-nutritional factors in aquaculture diets. However, previous experiments have shown that low dietary levels of saponins derived from Quillaja saponaria Molina do have growth promoting effects on common carp and Nile tilapia. Based on these experiments, we conducted an experiment in which we fed eluated saponin fractions from Q. saponaria and Trigonella foenum-graecum L. (fenugreek) to Nile tilapia in a respirometric system allowing for continuous measurement of oxygen consumption. Saponins were eluated with consecutive methanol/water concentrations (v/v, 40/60, 60/40, 80/20) resulting in three different eluates for each plant. Fractions chosen were the 80% methanol eluate from Q. saponaria (80QS) and all three eluates...

Ecological agriculture- a way towards sustainable agricultural practice
Provedor de dados: 21
Autores: Znaor, Darko; Bošnjaković, Branko.
Today, and especially in the years to come, agriculture, as well as all other human activities, will have to pay much more attention to their environmental impacts. In other words, it is expected that in the near future only technologies which care about environmental aspects will be promoted and accepted by policy makers, scientists, consumers, and society in general. This is not surprising since the environmental problems are among the most urgent ones our civilization will have to tackle and solve. This demand for more careful stewardship of environment is also acknowledged by philosophy of sustainable development - a widely recognized concept and necessity of future development.     Although established at the very beginning of this century, ecological...

Short-term effects on productivity and egg quality in nutrient-restricted versus non-restricted organic layers with access to different forage crops
Provedor de dados: 21
Autores: Horsted, Klaus; Hammershøj, Marianne; Hermansen, John E.
Two experiments were conducted to study the effects of different forage crops on productivity and some egg quality parameters of small flocks of organic laying hens fed whole wheat or concentrates. Each experiment was carried out in a split plot design with two different forage crops and two types of supplementary feed (typical concentrate for organic layers versus whole wheat) with three replications. In the first experiment the tested forage crops were of a well-established grass/clover and a mixture of forbs (Fagopyrum esculentum, Phacelia tanacetifolia and Linum usitatissimum). In the second experiment the tested forage crops were a well-established grass/clover and chicory (Cichorium intybus cv. Grassland Puna). The results on productivity and egg...

Provedor de dados: 21
Autores: Schjønning, P.; Thomsen, I. K.; Moldrup, P.; Christensen, B. T.
Quantification of in situ soil microbial activity is indispensable in order to improve manipulation of nutrient turnover in soil and optimize crop nutrient supply. We sampled 100 cm3 cores of undisturbed arable soil at three locations along a naturally occurring clay gradient (L1: 11% clay; L3: 22% clay; L5: 34 % clay). The cores were drained to seven different matric potentials in the range –15 to –1500 hPa and gas diffusion determined prior to a 4 week incubation at 20oC in the dark. For all soils the net nitrification increased with water content to a maximum (L1: 12.1, L3: 10.3 and L5: 8.2 g NO3-N g-1 soil) and then decreased with further increase in water content. The water content at maximum nitrification was 0.26, 0.37 and 0.42 m3 m-3,...

Healthy replacement heifers are one of the foundations of a healthy dairy herd. Farm management and rearing systems in Switzerland provide a wide variety of factors that could potentially be associated with intramammary infections (IMI) in early lactating dairy heifers. In this study, IMI with minor mastitis pathogens such as coagulase-negative staphylococci (CNS), contagious pathogens, and environmental major pathogens were identified. Fifty-four dairy farms were enrolled in the study. A questionnaire was used to collect herd level data on housing, management and welfare of young stock during farm visits and interviews with the farmers. Cow-level data such as breed, age at first calving, udder condition andswelling, and calving ease were also recorded....

Gross phosphorus fluxes in a calcareous soil inoculated with Pseudomonas protegens CHA0 revealed by 33P isotopic dilution
Provedor de dados: 21
Autores: Meyer, Gregor; Bünemann-König, Else; Frossard, Emmanuel; Maurhofer, Monika; Mäder, Paul; Oberson, Astrid.
Inoculation with phosphorus (P) solubilizing bacteria is being proposed to increase P availability for plants by mineralization and solubilization of non-available soil and fertilizer P. Solubilization of inorganic P compounds by bacterial strains has repeatedly been shown on agar plates and in liquid media. However, the effects of inoculation on P availability to plants growing in soils, either in pot or field studies, are inconsistent and do not allow to separate between direct effects on P availability and indirect effects such as improved plant health. This differentiation could be achieved using 33P isotopic labeling. We applied the 33P isotopic dilution method in a pot and in an incubation experiment to study gross P fluxes in a calcareous soil...

Organic agriculture requires cultivars that can adapt to organic crop management systems without the use of synthetic pesticides as well as genotypes with improved nutritional value. The aim of this study encompassing 16 experiments was to compare 23 broccoli cultivars for the content of phytochemicals associated with health promotion grown under organic and conventional management in spring and fall plantings in two broccoli growing regions in the US (Oregon and Maine). The phytochemicals quantified included: glucosinolates (glucoraphanin, glucobrassicin, neoglucobrassin), tocopherols (d-, c-, a-tocopherol) and carotenoids (lutein, zeaxanthin, b-carotene). For glucoraphanin (17.5%) and lutein (13%), genotype was the major source of total variation; for...

Microbial biomass and size-density factions differ between soils of organic and conventional agricultural systems
Provedor de dados: 21
Autores: Fliessbach, Andreas; Mäder, Paul.
Agricultural production systems have to combine management practices in order to sustain soil quality and also pro®tability. We investigated microbial biomass and size-density fractions of soils from a long-term field trial set up in 1978 at Therwil, Switzerland. It compares the economic and ecological performance of organic and conventional agricultural systems. Main differences of the systems were the amount and form of fertiliser as well as the plant protection strategy, whilst crop rotation and soil tillage were the same. Microbial biomass C and N as well as their ratios to the total and light fraction C and N pools in soils of the organic systems were higher than in conventional systems. This is interpreted as an enhanced decomposition of the easily...

Yield potential of chive: effects of cultivar, plastic mulch and fertilisation
Provedor de dados: 21
Autores: Suojala, Terhi.
Chive is a perennial herb, growing also natural in Finland. Commercial production of the herb is very small in our country, but large amounts of chive are imported. This fact has aroused interest in investigating the opportunities of producing chive using modern cultivation techniques. Effects of cultivar, plastic mulch as ground cover and fertilisation on yield were studied in field experiments over three years. In the experiments, the most productive cultivars or populations (a Finnish population “Hankoniemi”, a Dutch population “Tavallinen” and a German cultivar ‘Grolau’) produced 10–20% higher yields than the less productive cultivars. There were no clear differences in the yield quality between the cultivars. Black plastic mulch was effective in...

The potential of silicate rock dust to control pollen beetles (Meligethes spp.)
Provedor de dados: 21
Autores: Daniel, Claudia; Dierauer, Hansueli; Clerc, Maurice.
In organic agriculture, treatments with rock dusts for soil amendment, disease prevention, or insect control have a long tradition. Clinoptilolite (a naturally occurring zeolite) was tested against pollen beetle Meligethes spp. in organic and IPM oilseed rape fields in order to find a control strategy compatible with the guidelines for organic and IPM agriculture in Switzerland. Dust and spray applications were evaluated in several large-scale field trials from 2008 to 2011. Dust applications using 300-750 kg/ha pulverized Clinoptilolite (particle size &lt; 0.1 mm; product Klinofeed, available from Unipoint, Switzerland) were applied using a drop-box fertilizer spreader or a Vicon pendulum spreader. For spray applications the same Clinoptilolite (product...

The anthelmintic efficacy of five plant products against gastrointestinal trichostrongylids in artificially infected lambs
Provedor de dados: 21
Autores: Hördegen, P.; Hertzberg, H.; Heilmann, J.; Langhans, W.; Maurer, V.
Forty-eight helminth-free lambs were divided into eight groups (A–H) of six animals. Groups A–G were infected artificially with 10 000 third stage larvae of Haemonchus contortus and 20 000 third stage larvae of Trichostrongylus colubriformis, whereas group H remained uninfected. Thirty days post-infection the lambs were treated orally with a single dosage several products.  Only the ethanol extract of F. parviflora caused a strong reduction of the faecal egg counts (100%) and a 78.2 and 88.8% reduction of adult H. contortus and T. colubriformis on day 13 post-treatment. The extract was as effective as the reference compound pyrantel tartrate. Therefore, the ethanol extract itself or single constituents of F. parviflora could be a promising alternative...

The characterization of the soil biological quality of organic viticulture can be achieved by analyzing soil nematofauna
Provedor de dados: 21
Autores: Coll, P; Le Cadre, E; Mérot, A; Villenave, C.
Soil nematofauna is a bioindicator that can highlight changes in biological functioning when changing agricultural practices. In the present study, the effects of conversion of vineyards to organic agriculture on biological soil quality were evaluated. Twenty four conventional plots and organic plots in Cruscades (Aude) were studied: they were divided into four groups: (1) conventional, (2) converted for 7 years (Bio 7 years), (3) converted for 11 years (Bio 11) and (4) converted for 17 (Bio 17). The nematofauna was analyzed in 96 soil samples (four samples per plot) taken from the surface layer of soil (0-15 cm). The more longer the conversion of plots to organic viticulture, the higher the biological activity of the soil; it is the abundance of non-plant...

Autores: Moschitz, Heidrun; Roep, Dirk; Brunori, Gianluca; Tisenkopfs, Talis.
Editorial to the Special Issue on "Learning and Innovation Networks for Sustainable Agriculture: Processes of Co-evolution, Joint Reflection and Facilitation".     There is growing recognition that the technological and organizational solutions the agricultural sector has undertaken in the past are not always compatible with the constraints and opportunities that the rural economy and society will face in the next future. This has generated an increased emphasis on transition towards new business, technological and policy models that address the challenge of sustainability. Innovation is key to transition, but the institutions that are charged with fostering innovation are often locked into old approaches and methods of intervention. The linear view of...

Lactic acid fermentation for refining proteins from green crops and obtaining a high quality feed product for monogastric animals
Provedor de dados: 21
Autores: Santamaria-Fernandez, Maria; Molinuevo-Salces, Beatriz; Kiel, Pauli; Steenfeldt, S.; Uellendahl, Hinrich; Lübeck, Mette.
Nowadays, the organic farming sector is growing at a fast pace in Europe while needs to face the lack of organic protein sources and in particular, feeding monogastric animals is becoming more and more urgent. Green biorefinery concepts might become the suitable solution for the sustainable production of organic protein-rich feeds from green crops. In this context, red clover, clover grass, alfalfa and oilseed radish were studied as possible feedstocks for the development of an organic biorefinery system in Northern Europe. For this purpose, the green crops were processed into a nitrogen-rich protein concentrate, a fiber-rich press cake, and a residual stream of soluble nutrients (brown juice). The process, which involved a novel protein refining technique...

Species interactions between forbs and grass-clover contribute to yield gains and weed suppression in forage grassland mixtures
Provedor de dados: 21
Autores: Cong, W.-F.; Suter, M.; Lüscher, A.; Eriksen, J.
Grass-legume mixtures characterized by high productivity, efficient nitrogen (N) use and strong weed suppression were proposed to increase sustainability of grassland production. Adding competitive forbs to grassclover mixtures can be expected to further enhance the high productivity of grass-clover mixtures. This study investigates whether and to what extent adding forbs to a grass-clover mixture results in yield gains, and estimates the contributions of forb species (identity effect) and interactions with the grass-clover mixture (diversity effect) to these gains. It further examines the effectiveness of weed suppression in forb-containing grass-clover mixtures. Fifteen pure and mixed stands, all comprising the grass Lolium perenne L. and the legume...

Weinvestigated the influence of the level of fresh alfalfa supplementation on fat skatole and indole concentration and chop sensory attributes in grazing lambs. Four groups of nine male Romane lambs grazing a cocksfoot pasturewere supplemented with various levels of alfalfa for at least 60 days before slaughter. Perirenal fat skatole concentration was higher for lambs that consumed alfalfa than for those that consumed only cocksfoot. The intensity of ‘animal’ odour in the lean part of the chop and of ‘animal’ flavour in both the lean and fat parts of the chop, evaluated by a trained sensory panel, increased from the lowest level of alfalfa supplementation onwards and did not increase further with increasing levels of alfalfa supplementation. The outcome of...

Heterogeneity of protected crop colonization by beneficial insects: role of crop management and landscape context
Provedor de dados: 21
Autores: Aviron, Stéphanie; Perraudin, M.; Redondo, S.; Varennes, Y-D.; Lefèvre, Amélie.
Enhancing insect pest control by their natural enemies is considered as a promising crop protection strategy in organic vegetable production systems. In Mediterranean areas, native natural enemies such as mirid bugs (Heteroptera: Miridae) settle spontaneously in protected vegetable crops and can play an important rolefor pest regulation, which remains however very heterogeneous from field to field and hardly predictable. The present study is part of the project REGABRI, which aims at identifying key factors of colonization of organic and conventional protected tomato crops by mirid bugs in Roussillon area. A first survey in 2010-2011 on 34 crops showed that mirids abundances in crops vary according to management practices and landscape features in the...

Australia's original Demeter Farm (1934-1954)
Provedor de dados: 21
Autores: Paull, John.
Two members of Rudolf Steiner’s Experimental Circle were the first to establish a Demeter Farm in Australia. In 1934 Ileen Macpherson (1898-1984) and Ernesto Genoni (1885-1964) founded their ‘Demeter Biological Farm’ on the Princes Highway in Dandenong, Victoria. They were guided by Steiner’s book of his Agriculture Course (1924). They managed their 40 acre farm using biodynamic (BD) practices for the next two decades. Ileen and Ernesto pioneered biodynamic and thereby organic farming in Australia. They were the first to adopt the name ‘Demeter’ for an Australian BD enterprise. This was before the terms ‘biodynamic farming’ and ‘organic farming’ had any currency (which date from 1938 and 1940 respectively). They worked their BD farm for two decades until...

Do stocking rate and a simple run management practice inﬂuence the infection of laying hens with gastrointestinal helminths?
Provedor de dados: 21
Autores: Heckendorn, F.; Häring, D.A.; Amsler, Z.; Maurer, V.
The aim of this experiment conducted at four sites in Switzerland was to investigate the transmission and infectivity of the two main helminth parasite species of poultry (Ascaridia galli and Heterakis gallinarum) in outdoor runs with two different stocking rates.  Additionally, the inﬂuence of a simplemanagement practice (mowing of run) on helminth transmission was studied. Three run types were created on each site: runs C served as control (stocking rate 10 m2/hen, no management), runs B corresponded to runs C but were managed (10 m2/hen, management). In runs A stocking rates were doubled compared to control runs (5 m2/hen, no management). During two subsequent layer ﬂocks, a set of parasitological parameters (faecal egg counts (FECs), prevalence, worm...

USE OF NON-INVASIVE RGB IMAGING TO ASSESS  THE CANOPY STATUS IN ORGANIC VITICULTURE
Provedor de dados: 21
Autores: Diago, M.P; Fernandez-Novales, J.; Palacios, F.; Moreda, E.; Tardaguila, J.
In organic viticulture, canopy features such as leaf area, canopy porosity and fruit exposure are critical due their impact on fungal disease incidence and grape composition. An adequate and accurate assessment of the canopy status is the first step towards appropriate and effective grapevine canopy management, therefore an easy, non-invasive, robust method to evaluate the main features of a grapevine canopy is needed. In this work a protocol for canopy status assessment based on non-invasive RGB imaging is presented and used to ascertain differences in the canopy status of grapevines grown under different degraded and non-degraded soil conditions. RGB images were processed using a classification algorithm based on the Mahalanobis distance, and then the...

Perennial survival of common bunt (Tilletia tritici) in soil under modern farming practice
Provedor de dados: 21
Autores: Borgen, Anders.
Three years of field trials in Denmark have shown that common bunt (Tilletia tritici) is able to infect wheat in crop rotations with several intercrops between susceptible crops. This contradicts most previous literature which concluded that common bunt is a seed-borne pathogen only able to infect through the soil in cases where wheat is grown in two consecutive years. It is argued that the reason for this change in pathogenicity can be explained by a change in farming practice

Autores: Løes, Anne-Kristin.
Laying hens are specialized for egg production, and high costs for slaughtering challenges the utilization of killed hens for food purpose. Alternative utilization, such as for production of meat and bone meal, may be hampered by lack of rendering plants. E.g. in Norway, hens are commonly killed by gassing on farm, and transported to a centralized incineration plant. The bodies contain high amounts of nutrients, which may be utilized as fertilizer. A study was conducted to measure the fertilization effect of residues after hydrolysis of grinded slaughtered hens, and to explore the decomposition of chopped killed complete hens. This paper presents the main results.

Analysen af nye forbrugsdata fra GfK ConsumerScan indikerer, at husholdninger med et højt økologiforbrug spiser relativt meget frugt og grønt, men lidt kød. Selvom der ofte betales en merpris for økologiske varianter, viser undersøgelsen samtidig, at den økologiske forbruger ikke bruger flere penge på mad end andre. For alle forbrugergrupper står supermarkederne for det største salg af økologiske varer, men derudover adskiller den økologiske forbruger sig ved at købe flere varer over internettet og i specialbutikker.

Beyond Equal: From Same but Different to the Doctrine of Substantial Equivalence
Provedor de dados: 21
Autores: Paull, John.
A same-but-different dichotomy has recently been encapsulated within the ill-defined concept of “substantial equivalence”. By invoking this concept the genetically modified organism (GMO) industry has escaped the rigors of safety testing that might otherwise apply.     The curious concept of “substantial equivalence” grants a presumption of safety to GMO food. This presumption has yet to be earned, and has been used to constrain labelling of both GMO and non-GMO food. It is an idea that well serves corporatism. It enables the claim of difference to secure patent protection, while upholding the contrary claim of sameness to avoid labelling and safety scrutiny. It offers the best of both worlds for corporate food entrepreneurs, and delivers the worst of both...

COLIWAVE: a simulation model for survival of E. coli O157:H7 in dairy manure and manure-amended soil
Provedor de dados: 21
Autores: Semenov, A.V.; Franz, E.; van Bruggen, A.H.C.
• A simulation model was developed to investigate the relative effects of temperature, oxygen concentration, substrate content and competition by autochthonous microbial community on the oscillatory behaviour and survival of Escherichia coli O157:H7 in manure and manure-amended soil. The overall decline in E. coli O157:H7 was primarily determined by competition with autochthonous copiotrophic bacteria simulated by an inter-specific competition term according to Lotka-Volterra. Oscillations of bacterial populations were attained by the relationships between relative growth and death rates with readily available substrate content. The model contains a logistic and exponential relation of relative growth and death rates, respectively, of E. coli O157:H7 and...

Decomposer biomass in the rhizosphere to assess rhizodposition
Provedor de dados: 21
Autores: Christensen, Soren; Bjornlund, Lisa; Vestergård, Mette.
Quantification of the organic carbon released from plant roots is a challenge. These compounds of rhizodeposition are quickly transformed into CO2 and eventually bacterial biomass to be consumed by bacterivores (protozoa and nematodes). Microbes stimulate rhizodeposition several-fold so assays under sterile conditions give an unrealistic value. Quantifying bacterial production from H-3-thymidine incorporation falls short in the rhizosphere and the use of isotopes does not allow clear distinction between labeled CO2 released from roots or microbes. We reduced rhizodeposition in 3-5 week old barley with a 2 week leaf aphid attack and found that biomass of bacterivores but not bacteria in the rhizosphere correlated with plant-induced respiration activity...

Greenhouse Gas Emissions from Conventional, Agri-Environmental Scheme, and Organic Irish Suckler-Beef Units
Provedor de dados: 21
Autores: Casey, J. W.; Holden, N.M.
The problems of overproduction within the European Union countries and the environmental impact of agriculture have lead to the introduction of schemes that aim to reduce both. Beef (Bos taurus) production forms a large component of the Irish agricultural industry and accounts for more than one quarter of agricultural economic output. Recently, the European CAP (Common Agricultural Policy) has been re-evaluated to include supplementary measures that encompass the environmental role of agriculture rather than just the production role. A life cycle assessment (LCA) method was adopted to estimate emissions per kilogram of CO2 equivalent per kilogram of live weight (LW) leaving the farm gate per annum (kg CO2 kg−1 LW yr−1) and per hectare (kg CO2 ha−1 yr−1)....

LOCALISATION AND CONCENTRATION OF ORGANIC FARMING IN THE 1990'S - THE DANISH CASE
Provedor de dados: 21
Autores: Frederiksen, Pia; Langer, Vibeke.
This study explores the localisation of organic farms in Denmark for the three years 1994, 1997 and 2001, on a county and parish level. Spatial concentration is found in counties with a high share of milk producers, but also in the counties, which contain the two largest urban centres. General regional specialisation of the agricultural sector in Denmark contributes to the explanation of concentration patterns of organic conversion, but other factors like a regional favourable policy climate and -support also appear to play a role. Major variations in concentration within regions are found, suggesting that local factors play an important role for the explanation of spatial patterns of organic conversion.

Challenges in modelling dissolved organic matter dynamics in agricultural soil using DAISY
Provedor de dados: 21
Autores: Gjettermann, B.; Styczen, M.; Hansen, H.C.B.; Vinther, F.P.; Hansen, S.
Because dissolved organic matter (DOM) plays an important role is terrestrial C-,N-and P-balances and transport of these three components to aquatic environments, there is a need to include it in models. This paper presents the concept of the newly developed DOM modules implemented in the DAISY model with focus on the quantiﬁcation of DOM sorption/desorption and microbial-driven DOM turnover. The kinetics of DOM sorption/desorption is described by the deviation of the actual DOM concentration in solution from the equilibrium concentration, Ceq. The Ceq is soil speciﬁc and estimated from pedotransfer functions taking into account the soil content of organic matter, Al and Fe oxides. The turnover of several organic matter pools including one DOM pool are...

Transformações da terra: para uma perspectiva agroecológica na história.
Provedor de dados: 21
Autores: Worster, Donald.
O artigo discute a constituição do campo da história ambiental, que se deu nos anos 70 em meio aos debates sobre a crise ecológica e a eclosão do movimento ambientalista. Esta história não aceita a noção de que as sociedades humanas não produzem alterações ambientais significativas, e interpela as condições específicas dessa interação recorrente. O sistema agroecológico representa um dos casos mais típicos de rearranjo da atividade humana sobre os ecossistemas naturais, em uma relação complexa de interação entre plantas nativas, vegetação forasteira, fertilidade dos solos e diversas práticas agrícolas. O itinerário dessas mudanças é essencial para se compreender a história do ponto de vista ambiental

The Future of Organic Agriculture: Otopia or Oblivion?
Provedor de dados: 21
Autores: Paull, John.
Organic agriculture could feed the world, but will it? A state of Otopia, an organic Utopia of 100% organic food and organic agriculture, is a dream, or is it a pipe-dream? And if a dream, might it manifest in four decades or 54 decades? The stated goal of the organic movement is the adoption worldwide of organic agriculture. That task has a long path to travel, with organic agriculture currently accounting for 0.8% of agricultural land worldwide. Two roads to Otopia are extrapolated from the rate of growth of global organics exhibited over the past decade. If an arithmetic rate of growth  - think simple interest - continued indefinitely then a state of Otopia would take 544 years (2553). Under a geometric growth scenario - think compound interest - Otopia...

Computer model for simulating the long-term dynamics of annual weeds: from seedlings to seeds
Provedor de dados: 21
Autores: Rasmussen, Ilse A.; Holst, Niels.
We developed a simple model to predict seed production from seedling density and estimated its six parameters for Chenopodium album and Papaver rhoeas from literature data, supplemented with field data on P. rhoeas seed production in Denmark. Parameter values were specified by their expected ranges rather than just point estimates, which enabled us to determine the expected ranges of seed production at given seedling densities. The model will be incorporated into a larger model framework presented earlier for a more complete description of annual weed seedbank dynamics in a crop rotation. We found the seed production (y) of P. rhoeas to be larger than reported earlier from UK; the relation to weed biomass (x) per m2 was curvilinear, y=6015∙x0.8153 seeds...

Autores: Arncken-Karutz, Christine.
Welche unterschiedlichen Qualitäten von Weizen entstehen durch die biologischdynamische, die organischbiologische und die konventionelle Wirtschaftsweise? Wie können sie ganzheitlich erfasst werden? Wie reagieren die Pflanzen als Ganze und als Bestand auf die verschiedenen Anbauweisen? Mit diesen Fragen wurde während der Jahre 1998 bis 2000 die Winterweizensorte „Tamaro” in einem Langzeit-Feldversuch (DOK-Versuch) beobachtet und untersucht. Dabei wurde Wert auf Erfahrungen gelegt, die mit Hilfe der "unbewaffneten" menschlichen Sinne gemacht werden können. So kann der Begriff "Qualität" mit konkreten Erlebnissen gesättigt werden, die jeder aufmerksame und interessierte Mensch haben kann. Solche Erlebnisse brauchen Landwirte und Konsumenten für ihre...

Cultural and Biological Determinants in the Evaluation of Urban Green Spaces
Provedor de dados: 21
Autores: Home, Robert; Bauer, Nicole; Hunziker, Marcel.
Dramatically increasing urbanization is observable worldwide and brings pressure on space within urban areas as the built environment intensifies.  Considerable evidence suggests that contact with nature is important for city dwellers, although it is not known whether residents’ appreciation of the forms of urban green spaces is constant across different contexts. More specifically, it has not yet been shown whether our appreciation of nature is innate and inherently human, is  cultural and something that we learn, or is a mixture of both. This article describes an exploratory study consisting of 17 interviews carried out in Zurich, Switzerland. Kelly’s repertory grid technique is used to identify preferred urban landscapes, which were contrasted with...

Comparison of performance and fitness traits in German Angler, Swedish Red and Swedish Polled with Holstein dairy cattle breeds under organic production
Provedor de dados: 21
Autores: Bieber, A.; Wallenbeck, A.; Spengler Neff, A.; Leiber, F.; Simantke, C.; Knierim, U.; Ivemeyer, S.
Although the use of local breeds is recommended by organic regulations, breed comparisons performed under organic production conditions with similar production intensities are scarce. Therefore, we compared data of local and widely used Holstein dairy cattle breeds from 2011 to 2015 regarding production, fertility and health from German and Swedish organic farms with similar management intensities within country. In Germany, the energy-corrected total milk yield tended to be lower in the local breed Original Angler Cattle (AAZ, 5193 kg) compared to the modern German Holstein Friesian breed (HO, 5620 kg), but AAZ showed higher milk fat and protein contents (AAZ v. HO: 5.09% v. 4.18% and 3.61% v. 3.31%, respectively). In Sweden, the widely used modern...

Autores: Petersen, B.M.; Jensen, L.S.; Berntsen, J.; Hansen, S.; Pedersen, A.; Henriksen, T.M.; Sørensen, P.; Trinsoutrot, I.
A computer model is presented, which describes the transformations of C and N in the soil. The development has been divided into two interdependent tasks, the first being development of long-term SOC simulation capabilities, and the second being short-term simulations of C and N, as described in this paper. A number of existing, independent laboratory experiments, covering a range of amendments, have been used for this task. The amendments includes a variety of different crop residues and animal manure. These experiments have included measurements of 13C, 14C and 15N in various pools, and the model facilitates the simulation of these isotopes. Non-linear, automated optimisation procedures were utilised wherever feasible. The model generally yielded good...

Rhagoletis cerasi: Oviposition reduction effects of oil products
Provedor de dados: 21
Autores: Daniel, Claudia.
The European cherry fruit fly, Rhagoletis cerasi (L.) (Diptera: Tephritidae), is a highly destructive pest. Methods to control it are limited and alternatives are needed.Observations of cherry fruit flies suggest that females exert much effort to penetrate cherries at color change stage (from green to yellow) for oviposition. Therefore, the question arose as to whether a physical barrier on the fruit surface could reduce oviposition. The effects of different commercial horticultural oil products on R. cerasi oviposition were evaluated in a series of laboratory, semi-field and field experiments. In the laboratory experiments, the rate of successful oviposition on fruits treated with 0.25% v/v of the rapeseed oil product Telmion was significantly reduced by...

Autores: Mattila, Timo; Manninen, Marja; Rikkonen, Pasi; Kymäläinen, Hanna-Riitta.
Structural change in agriculture means a continuous need for investing in farm production. It is essential for the sustainable operations and the economy of the farm that such investments are successful. In this research, different stages of the investment process of farms were studied as well as the use of information and the success perceived during the investment process. The study was carried out with mail surveys and telephone interviews on the Finnish Farm Accountancy Data Network (FADN) farms. The most challenging investments were in animal husbandry buildings and, as to these investments, the comparison of alternatives was the most challenging stage. For most investments, the planning phase was considered more challenging than the implementation....

The success of weed management aimed at depleting the regenerative structures of perennial weeds depends largely on the sprouting activity of rhizome and root buds. Seasonal variation in sprouting of these buds on Cirsium arvense, Sonchus arvensis and Elymus repens was studied for plants collected from Denmark, Finland, Norway and Sweden. At 2-week intervals from July to October, 5-cm fragments of roots or rhizomes were cutfrom plantsgrown in buckets and planted into soil in pots, half of which were placed immediately into growth chambers at 18�C for 4 weeks. The other half of the pots were initially placed in a dark room at 2�C for 4 weeks before being transferred to the same growth chamber, also for 4 weeks. During the growth chamber period, the numbers...

The credit point system: an innovative approach to enhance biodiversity on farmland
Provedor de dados: 21
Autores: Jenny, Markus; Zellweger-Fischer, Judith; Balmer, Oliver; Birrer, Simon; Pfiffner, Lukas.
We developed a credit point system to assess “wildlife-friendliness” at the farm scale.  Farmers can choose and gain points from 32 habitat management options, most of which account for quantity, quality and spatial distribution of ecological compensation areas (options of the Swiss agri-environment scheme). Additionally, points can be scored by specific arable and grassland measures. Farmers are free to decide which measures to implement. We evaluated the credit point system on 133 farms (2009–2011) in the Swiss Lowland Plateau. Occurrence and density of plants, grasshoppers, butterflies and farmland birds were recorded on these farms as biodiversity indicators. The scored points were positively correlated with the majority of biodiversity indicators....

The quality of organic products
Provedor de dados: 21
Autores: LAIRON, D.
The sustainable development of ecological agriculture productions (AB) should be based on their overall quality, in the framework of nutritional recommendations and public action plans. In France, the PNNS (Nutrition and health national plan) advises to increase intake of fruits and vegetables, unrefined cereals, fibres and calcium and to reduce saturated fat. In addition, healthy foods should avoid any microbiological or chemical contaminants. The question arose of the adequacy of organic productions. For that purpose, the AFSSA (the French food safety agency) established an expert group headed by the author to conduct a sounded review of international scientific literature. The AFSSA report (2003) made conclusions as summarized here. Regarding the...

A  model for fossil energy use in Danish agriculture used to compare organic and conventional farming
Provedor de dados: 21
Autores: Dalgaard, T.; Halberg, N.; Porter, J.R.
Knowledge about fossil energy use in agricultural systems is needed, because it can improve the understanding of how to reduce the unsustainable use of limited energy resources and the following greenhouse gas emissions. This study describes and validates a model to assess fossil energy use in Danish agriculture; gives an example of how the model can be used to compare organic and conventional farming; and discusses the implications and potentials of using the model to simulate energy use in scenarios of agricultural production. The model is a development of an existing model, which was too coarse to predict measured energy use on Danish farms. The model was validated at the field operational, thecroptype, and the national level, and can supplement the...

Grazing with heifers and sows alone or mixed: herbage quality, sward structure and animal weight gain
Provedor de dados: 21
Autores: Sehested, Jakob; Søegaard, Karen; Danielsen, Viggo; Roepstorff, Allan; Monrad, Jesper.
The aim of the present study was to compare the effect of mixed grazing (MI) by sows and heifers with alternate grazing (AL) or grazing heifers (HN) and sows (SN) alone on animal weight gain, sward structure, herbage quality and composition, and selection during grazing. Mixed or alternate grazing consistently improved the weight gain in both heifers and sows, compared with grazing one species alone, but the positive effect was statistically significant only for heifers. The herbage quality of the MI and AL systems was better compared with the SN system, but not clearly better compared with the HN system. The total animal weight gain (heifers+sows) and estimated herbage intake per hectare were also higher in the MI and AL systems compared with SN and HN...

Technical and economic performances in organic sheep meat production: observations of breeding networks and experimental farms
Provedor de dados: 21
Autores: BENOIT, M.; LAIGNEL, G.
A network of 42 sheep farms (including 13 in organic farming (OF)) shows that the gross margin per ewe is 24% lower in OF in the mountains because of high food costs and comparable in the lowlands because of the high level of food self-sufficiency based on the cultivation of fodder and grain; incomes are identical when structural costs are comparable. An analysis of four demonstration farms shows that, given the different conditions, specific livestock management is required depending on the presence of tillable land or not. If their proportion is limited, lambings are equally distributed between spring and autumn in order to maximise fodder self-sufficiency. When crops are possible, lambings are focused on autumn (with good sale prices), which requires...

Faba bean in cropping systems
Provedor de dados: 21
Autores: Jensen, Erik Steen; Peoples, Mark B.; Hauggaard-Nielsen, Henrik.
The grain legume/pulse faba bean (Vicia faba L.) is grown world-wide as protein source for food and feed and simultaneously faba bean offers ecosystem services such as N2 fixation and diversification of cropping systems. Even though the global average grain yield has almost doubled during the recent 50 years the area of faba beans has declined with 56% in the same period. This is especially the case for some of the former big producer countries such as China and Egypt. The yield season-to-season of faba bean and development of an industrialized agriculture based on fossil fuels (= N fertilizers, heavy mechanization) are some of the explanations for this development. Studies of faba bean in cropping systems have focussed on the effect of faba bean as a...

Field weed population dynamics: a review of model approaches and applications
Provedor de dados: 21
Autores: Holst, N.; Rasmussen, I.A.; Bastiaans, L.
Mathematical modelling is a commonly used tool for studying the long-term dynamics of weed populations in agriculture. This was reflected in our review by the large number of scientific papers (134 original publications) and the continuing need to gain an overview over this fast developing field (20 previous review papers were found). In this article, we provide a more comprehensive review than earlier seen, striving to include all relevant publications. Thus, we cover models of the population dynamics of 60 weed species in 40 crops. An online, accompanying database provices an indexed bibliography. Despite the large variation in crops, weeds and geography, the models were surprisingly similar in their approach: structured around the weed life cycle,...

Nutrient cycle on organic farms: stall balance of a suckler herd and beef bulls
Provedor de dados: 21
Autores: Haas, Guido; Wetterich, Frank; Köpke, Ulrich.
In organic agriculture, the internal farm nutrient cycle must be quantified to ensure high system productivity along with environmentally sound production processes. In contrast to common farmgate and field balances, budgeting at the stable level is seldom undertaken. When budgeting mixed farming systems, a substantial lack of nutrients can be detected in the nutrient flow chain "forage and straw input - stable - manure output". Therefore, stable balances focus on a central component of whole farm nutrient budgets for developing efficient nutrient management strategies. At the experimental farm for organic agriculture Wiesengut in Hennef, Germany, all solid mass flows for a suckler herd and a herd of beef bulls were measured. Relative balance values...

Effects of conventionally bred and Bacillus thuringiensis  (Bt) maize varieties on soil microbial biomass and activity
Provedor de dados: 21
Autores: Fliessbach, Andreas; Messmer, Monika; Nietlispach, Bruno; Infante, Valentina; Mäder, Paul.
Abstract  Genetically modified (GM) maize containing genes from the soil bacterium Bacillus thuringiensis (Bt) was cultivated on 29% of the total maize production area worldwide in 2009. Most studies to date compare Bt-maize varieties with their near isogenic lines; however, there is little information on the variability of conventional maize breeding lines and how the effects of Bt varieties are ranked within. In our study on the potential risks of Bt-maize varieties, we analyzed tissue quality and compared the effects of ten conventional and GM maize varieties on soil microbiological properties in a replicated climate chamber experiment. All maize varieties were cultivated twice in the same soil microcosm. Shoot yields and soluble C in leaf tissue of Bt...

Autores: Majewsky, V.; Arlst, S.; Shah, D.; Sherr, C.; Jäger, T.; Betti, L.; Trebbi, G.; Bonamin, L.; Klocke, P.; Baumgartner, S.
BACKGROUND: The last comprehensive review of experimental research on effects of homeopathic treatments on plants was published in 1984, and lacked formal predefined criteria to assess study quality. Since then several new studies with more advanced methods have been published.  OBJECTIVES: To compile a review of the literature on basic research in homeopathy with healthy plants with particular reference to studies investigating specific effects of homeopathic remedies.  METHODS: The literature search included English, French, German, Italian, Portuguese and Spanish publications from 1920 to April 2009, using predefined selection criteria. We included experiments with healthy whole plants, seeds, plant parts and cells. The outcomes had to be measured by...

Effects of sampling and extraction on deoxynivalenol quantification
Provedor de dados: 21
Autores: Hallier, Arnaud; Celette, Florian; David, Christophe.
Deoxynivalenol was extracted from wheat grain and quantified by GC-ECD. The quantification of deoxynivalenol can be critical, for example in certifying the amount of the mycotoxin in a lot and determining if this amount is over or under a fixed limit. Thus, an objective was to obtain representative samples to monitor DON quantification variability. We show that among the different steps of analysis the critical one is grain sampling. We also show that we were able to significantly improve the extraction rate without increasing the variability by using a longer extraction time with a magnetic agitator, and a grinding process which takes into account both the heterogeneous repartition of deoxynivalenol within wheat grains and different extraction rates...

Gruppenhaltung ferkelführender Sauen in der Öko-Landwirtschaft
Provedor de dados: 21
Autores: Früh, Barbara.
Bio-Schweinefleisch liegt voll im Trend. Insbesondere in Deutschland kann die Nachfrage nach wie vor nicht gedeckt werden. Die ökologische Schweinehaltung nimmt daher zu und Bio-Betriebe, die bereits Schweine halten, vergrößern oft ihre Bestände; andere Betriebe beginnen mit der Ferkelerzeugung oder der Schweinemast. Für diese Betriebe sind Haltungssysteme interessant, die sowohl arbeitswirtschaftlich und ökonomisch sind als auch die Bedürfnisse der Tiere durch eine artgerechte Haltung befriedigen. Die Gruppenhaltung ferkelführender Sauen wird diesen Kriterien gerecht.

Application of lactic acid bacteria in green  biorefineries
Provedor de dados: 21
Autores: Lübeck, Mette; Lübeck, Peter Stephensen.
Lactic acid bacteria (LAB) have extensive industrial applications as producers of lactic acid, as probiotics, as biocontrol agents and as biopreservatives. LAB play a large role in food fermentation and in silage processes, where crops such as grass, legumes, cereals or corn are fermented into high-moisture feed that is storable and can be used to feed cattle, sheep or other ruminants. LAB also have great applications within green biorefineries, with simultaneous production of protein-rich feed for monogastric animals, silage or feed pellets for ruminants and production of lactic acid or specific amino acids. In green biorefineries, fresh or ensiled wet biomass is mechanically fractionated into green juice and solid residues (press cake), where the plant...

Which carabid species benefit from organic agriculture? - a review of comparative studies in winter cereals from Germany and Switzerland
Provedor de dados: 21
Autores: Döring, Thomas; Kromp, Bernhard.
Data of comparative studies about carabid beetles in organically and conventionally managed winter cereal fields of central Europe, using the pitfall trapping method, were collected from the literature and unpublished data sources and were then pooled and analysed. According to an index, which was designed to calculate how much a species benefits from organic management, Carabus auratus turned out to benefit most. Some Amara species (A. familiaris, A. similata and A. aenea) as well as Pseudoophonus rufipes and Harpalus affinis also showed high index values. When analysing the traits of the carabids, the habitat preference was the most important variable for the differentiation of organic and conventional management. The stronger the preference for open...

Energy Utilization in Crop and Dairy Production in Organic and Conventional Livestock Production Systems
Provedor de dados: 21
Autores: Refsgaard, Karen; Halberg, Niels; Kristensen, Erik Steen.
Searching for livestock production systems with a high energy utilization is of interest because of resource use and pollution aspects and because energy use is an indicator of the intensification of production processes. Due to interactions between crop and livestock enterprises and between levels of different input factors and their effects on yields, it is proposed to analyze agricultural energy utilization through system modelling of data from farm studies. Energy use in small grains, grass-clover and fodder beets registered in organic and conventional mixed dairy farms was analyzed and used together with crop yields in order to model energy prices on three Danish soil types. Conventional crop yields were higher but they also used more indirect energy...

Forlænget kælvningsinterval - kan være en fordelagtig produktionsstrategi
Provedor de dados: 21
Autores: Christiansen, Hans Christian; Danfær, Allan; Sehested, Jakob.
En forlængelse af laktationsperioden og dermed kælvningsintervallet til 18 måneder giver mulighed for øget andel af grovfoder i rationen. Det skyldes, at der bliver forholdsvis færre dage i tidlig laktation, hvor tildelingen af koncentreret foder er størst. Et længere kælvningsinterval betyder endvidere færre golddage per årsko, idet antal golddage per laktation var uændret. En forlængelse af kælvningsintervallet betød, at laktationsydelsen steg fra 7.656 til 11.516 kg EKM. Omregnet til ydelse per årsko giver det 7.635 versus 8.006 kg EKM ved det forlængede kælvningsinterval, altså en stigning på 371 kg EKM sammenlignet med et traditionelt kælvningsinterval. Et normalt foderniveau er en forudsætning for at opnå denne ydelsesstigning ved at forlænge...

Simulating trends in crop yield and soil carbon in a long-term experiment – effects of rising CO2, N deposition and improved cultivation
Provedor de dados: 21
Autores: Berntsen, J.; Petersen, B.M.; Olesen, J.E.
Measurements of crop yield and soil carbon in the Bad Lauchstädt long-term fertiliser experiment were analysed with the FASSET model. The model satisfactorily predicted yield and soil carbon development in four treatments with no fertiliser, mineral fertiliser, farm yard manure and farm yard manure plus mineral fertiliser, respectively. However, there was a residual between the observed and simulated yield, which was correlated with year. This could be attributed to an increase in observed yields during the last six decades. Scenario analysis showed that the most probable explanation for this yield increase was the use of new crop varieties and/or pesticides, while the increase in atmospheric CO2 and changes in local N deposition were of lesser importance....

Evaluating On-Farm Biodiversity: A Comparison of Assessment Methods
Provedor de dados: 21
Autores: Gabel, Vanessa M.; Home, Robert; Stöckli, Sibylle; Meier, Matthias; Stolze, Matthias; Köpke, Ulrich.
Strategies to stop the loss of biodiversity in agriculture areas will be more successful if farmers have the means to understand changes in biodiversity on their farms and to assess the effectiveness of biodiversity promoting measures. There are several methods to assess on-farm biodiversity but it may be difficult to select the most appropriate method for a farmer’s individual circumstances. This study aims to evaluate the usability and usefulness of four biodiversity assessment methods that are available to farmers in Switzerland. All four methods were applied to five case study farms, which were ranked according to the results. None of the methods were able to provide an exact statement on the current biodiversity status of the farms, but each method...

Wildflower companion plants increase pest parasitation and yield in cabbage fields: Experimental demonstration and call for caution
Provedor de dados: 21
Autores: Balmer, Oliver; Géneau, Céline E.; Belz, Elodie; Weishaupt, Bettina; Förderer, Gerda; Moos, Sebastian; Ditner, Nadine; Juric, Ivan; Luka, Henryk.
Monocultures typical of intensive agriculture offer ideal conditions to specialized herbivores while depriving their natural enemies of habitat and nutritional resources. The resulting release of herbivores from both bottom-up and top-down control causes pest outbreaks in economically important crops. Boosting locally occurring natural enemy populations through species-specific habitat management to restore natural herbivore control has been much advocated but remains rarely tested in the field. Here, we investigated whether adding specifically selected flowering plants to monocultures increases parasitation rates of herbivores and crop yield. We performed replicated field experiments in 2 years and found that adding cornflowers (Centaurea cyanus) into...

Jordløsning i vækstsæsonen øger ikke N mineraliseringenen
Provedor de dados: 21
Autores: Thomsen, Ingrid Kaag; Sørensen, Peter.
Jordbearbejdning foretages almindeligvis for at klargøre jorden til såning eller for at nedmulde planterester og gødning.     Ligeledes kan jordbearbejdning finde sted både i og uden for vækstsæsonen i forbindelse med mekanisk ukrudtsbekæmpelse.   Der er en udbredt opfattelse af, at ukrudtsbekæmpelse, foretaget fx ved radrensning af rækkeafgrøder i vækstsæsonen, også øger mineraliseringen af kvælstof. En øget kvælstofmineralisering formodes at finde sted som følge af, at den mekaniske bearbejdning bryder jordknolde, hvorved der blotlægges organisk materiale, som nedbrydes. Samtidigt fremmer jordbearbejdningen luftskiftet i jorden, og betingelserne for omsætning forventes dermed forbedrede.    En øget kvælstofmineralisering som følge af jordbearbejdning...

Goklany stated that 20 % lower crop yields in organic farming would require 25 % more land use to produce the same amount of crop biomass, offsetting some of the advantages of organic agriculture with respect to biological diversity, inputs, and soil erosion, and that the experimental yields are not typical. Furthermore, he indicates that organic farming might not be sufficient to feed the world.

Organic and many ‘low input’ production standards for pigs require outdoor access, and as a consequence expose the animals to a wide range of potential endo- and ectoparasite infection sources. Conventional anthelmintics are used to control parasitic infections, but their preventive use is banned by the organic standards. The present paper investigates the potential of prevention of infection through better hygiene. Attempts were made to break the infection cycle through thorough pen cleaning 10 weeks after the pigs had been introduced to the pen. Although pen fouling can be reduced, the level of roundworm (Ascaris  suum) infection was not reduced. Regular deworming with conventional medication is still required in addition to good hygiene.

Provedor de dados: 21
Autores: Thomsen, Rikke; Edwards, Sandra E; Jensen, Bent Borg; Rousing, Tine; Sørensen, Jan Tind.
To investigate the extent to which the level of androstenone and skatole decreases with a decrease in live weight and/or age at slaughter of entire male pigs produced under organic standards, 1174 entire male pigs were raised in parallel in 5 organic herds, distributed across 4 batches in summer and winter. The median androstenone level was high for organic entire male pigs (1.9 µg/g), but varied greatly both within and between herds. Median skatole level was 0.05 µg/g, also with a wide range both within and between herds. Decreasing live weight over the range of 110±15.6 kg sd was found to decrease androstenone as well as skatole concentration, however, with different patterns of association.

Global situation for organic tree fruits
Provedor de dados: 21
Autores: Granatstein, David; Kirby, Elisabeth; Ostenson, Harold; Willer, Helga.
Consumer demand for organic tree fruit products in Europe and North America, the dominant organic food markets, has spurred increases in organic area and production globally. From 2008–2013, the area of production grew 109%, 42%, and 53% for organic temperate tree fruits, citrus, and tropical/subtropical fruits, respectively, with much lower growth for total area (non-organic plus organic) in these categories. Most organic tree fruits represent approximately 1–2% of total production area for a specific fruit; avocado is the exception, with 8% of avocado area worldwide under organic management. Mexico, Italy, and China are the top three countries in terms of organic tree fruit area, but not all countries segregate tree fruit crops in the organic statistics...

Insect-specific baculoviruses are increasingly used as biocontrol agents of lepidopteran pests in agriculture and forestry, and thy have been previously regarded as robust to resistance development by the insects. However, in more than a dozen cases of field resistance of codling moth Cydia pomonella to commercially applied C. pomonella granulovirus (CpGV) in German orchards, resistance ratios exceed 1000. The rapid emergence of resistance is facilitated by sex-linkage and concentration dependant dominance of the major resistance gene and genetic uniformity of the virus. When the gene is fixed, resistance levels approach 100.000-fold. Our findings highlight the need for development of resistance management strategies for baculoviruses.  (C)2007, American...

It was the production centre for the vibrantly-coloured engraved glass windows of the Goetheanum, and it was the crucible for evolving Rudolf Steiner’s Koberwitz lectures through to ‘biodynamic agriculture’, Steiner’s new agriculture for the world. In 1919 Guenther Wachsmuth (1893-1963) and Ehrenfried Pfeiffer (1899-1961) had set up a research laboratory in the basement of the Glass House. In 1924 the Agricultural Experimental Circle was founded at Koberwitz with the results to be reported to the Natural Science Section of the Goetheanum at Dornach. Ehrenfried...

Autores: Boregas, Katia Gisele Brasil; Mendes, Simone Martins; Waquil, José Magid; Fernandes, Geraldo Wilson.
A principal praga-alvo na cultura do milho é a lagarta-do-cartucho, Spodoptera frugiperda (J.E. Smith, 1797) (Lepidoptera: Noctuidae), que, pela sua ampla distribuição temporal e geográfica constitui-se em uma das espécies mais nocivas nas regiões tropicais das Américas. O objetivo foi avaliar o estádio de adaptação de S. frugiperda em 17 espécies hospedeiras, cultivadas ou selvagens, mais comuns no agroecossistema brasileiro. As plantas foram cultivadas em cinco épocas, entre 2006 e 2008, utilizando o milho como padrão. Larvas de S. frugiperda recém-eclodidas foram individualizadas e confinadas em copo plástico (50 mL), onde foram alimentadas com seções de folha nova de cada hospedeiro. O alimento foi substituído a cada dois dias por folhas frescas....

Community Assembly in Experimental Grasslands: Suitable Environment or Timely Arrival?
Provedor de dados: 21
Autores: Ejrnæs, R.; Bruun, H.H.; Graae, B.J.
It is hard to defend the view that biotic communities represent a simple and predictable response to the abiotic environment. Biota and the abiotic environment interact,and the environment of an individual certainly includes its neighbors and visitors in thecommunity. The complexity of community assembly calls forth a quest for general principles,yet current results and theories on assembly rules differ widely. Using a grassland microcosm as a model system, we manipulated fertility, disturbance by defoliation, soil/microclimate, and arrival order of species belonging to two groups differing in functional attributes. We analyzed the outcome of community assembly dynamics in terms of species richness, invasibility, and species composition. The analyses...

Autores: Duval, Julie; Bareille, Nathalie; Fourichon, Christine; Madouasse, Aurélien; Vaarst, Mette.
Veterinarians could be the expected sparring partners of organic dairy farmers in promoting animal health which is one of the main organic principles. However, in the past organic dairy farmers did not always consider veterinarians to be pertinent advisors for them. The objectives of this study are – from private veterinary practitioners’ point of views- i) to describe the roles of veterinarians today in organic dairy farmers’ animal health promotion strategies, ii) to identify factors related to organic farming which determine their role on organic dairy farms, and, iii) to identify opportunities for improvement of veterinarians’ advisory services for organic dairy herds.

An Analysis of Organic Agriculture in Turkey: The Current Situation and Basic Constraints
Provedor de dados: 21
Autores: Özbilge, Zeynep.
This article gives information about the current situation of Turkish organic agriculture, especially by comparing the official recognition for organic farming in the European Union with that of Turkey and summarizes the existing constraints. The analysis indicates that the further development of Turkish organic agriculture depends upon the development of the domestic organic market and Turkey has to fulfill a number of conditions to provide it. It is needed that the Turkish state both encourages organic production for the domestic market and supports organic agriculture by all means.

Abstract: The impact of treatments  with the pyrethrin insecticide Pyrethrum FS and the repellent kaolin product Surround WP to control the autumn forms of Dysaphis plantaginea Pass. (Homoptera: Aphididae), a major pest insect on apple, was assessed in one-year field experiments in Switzerland. Single and multiple applications of pyrethrin and kaolin were tested at different dates after apple harvesting in autumn 2002 when sexuales of the rosy apple aphid were present. Repeated applications of Surround WP in autumn significantly reduced the number of females in autumn and, consequently, the number of hatched fundatrices in spring. Single kaolin treatments were less effective. Unexpectedly, neither single nor multiple applications of the contact insecticide...

Autores: Fyfe, William S.; Leonardos, Othon H.; Theodoro, Suzi H.
The development process which humanity passed through favored a series of conquests, reflected in the better quality of life and longevity, however, it also provoked upsets and severe transformation in the environment and in the human food security. Such process is driving the ecosystems to be homogeneous, and, therefore,the nutrientsï¿½ supply, via nourishment. To change this panorama, the present work discusses the gains of incorporating the stonemeal technique as a strategic alternative to give back the essential fertile characteristics to the soils. This technology has the function of facilitating the rejuvenation of the soils and increasing the availability of the necessary nutrients to the full development of the plants which is a basic input for the...

Umstellung auf ökologischen Landbau: Wer profitiert?
Provedor de dados: 21
Autores: Nieberg, Hiltrud.
Die Umstellung auf ökologischen Landbau ist für die Mehrzahl der geförderten Betriebe erfolgreich verlaufen. Die Wirtschaftlichkeit der Umstellung wird allerdings deutlich von der Förderprämie und den Vermarktungsmöglichkeiten beeinflusst. Aufgrund von vergleichsweise günstigeren Vermarktungsbedingungen für pflanzliche Produkte haben Marktfruchtbetriebe in der Vergangenheit von der Umstellung besonders profitiert. Das durchschnittlich positive Ergebnis darf jedoch nicht darüber hinwegtäuschen, dass es Betriebsleiter gibt, die mit ihrem Umstellungsergebnis nicht zufrieden sind. Vor allem für Betriebsleiter, die keine höheren Preise für ihre Erzeugnisse erzielen, stellt sich häufig die Frage, ob die ökologische Wirtschaftsweise weitergeführt oder auf andere...

Catch crop strategy and nitrate leaching following grazed grass-clover
Provedor de dados: 21
Autores: Hansen, E.M.; Eriksen, J.; Vinther, F.P.
Cultivation of grassland presents a high risk of nitrate leaching. This study aimed to determine if leaching could be reduced by growing spring barley (Hordeum vulgare L.) as a green crop for silage with undersown Italian ryegrass (Lolium multiﬂorum Lam.) compared with barley grown to maturity with or without an undersown conventional catch crop of perennial ryegrass (Lolium perenne L.). All treatments received 0,60 or 120 kg of ammonium-N ha-1 in cattle slurry. In spring 2003, two grass-clover ﬁelds (3 and 5 years old, respectively, with different management histories) were ploughed. The effects of the treatments on yield and nitrate leaching were determined in the ﬁrst year, while the residual effects of the treatments were determined in the second year...

The influence of organic and conventional farming practices on the content of single nutrients in plants is disputed in the scientific literature. Here, large-scale untargeted LC-MS-based metabolomics was used to compare the composition of white cabbage from organic and conventional agriculture, measuring 1,600 compounds. Cabbage was sampled in 2 years from one conventional and two organic farming systems in a rigidly controlled long-term field trial in Denmark. Using Orthogonal Projection to Latent Structures-Discriminant Analysis (OPLS-DA), we found that the production system leaves a significant (p = 0.013) imprint in the white cabbage metabolome that is retained between production years. We externally validated this finding by predicting the production...

Agronomic aspects of strip intercropping lettuce with alyssum for biological control of aphids
Provedor de dados: 21
Autores: Brennan, Eric B.
Organic lettuce growers in California typically use insectary strips of alyssum (Lobularia maritima (L.) Desv.) to attract hoverflies (Syrphidae) that provide biological control of aphids. A two year study with transplanted organic romaine lettuce in Salinas, California investigated agronomic aspects of lettuce monoculture and lettuce-alyssum strip intercropping on beds in replacement intercropping treatments where alyssum transplants replaced 2 to 8% of the lettuce transplants, and in additive intercropping treatments where alyssum transplants were added to the standard lettuce density without displacing lettuce transplants. Alyssum and lettuce dry matter (DM) were determined at lettuce maturity. Alyssum transplants produced less shoot DM in the additive...

Does fruit-tree architecture manipulation affect the development of pests and pathogens? A case study in an organic apple orchard
Provedor de dados: 21
Autores: SIMON, S.; LAURI, P.E.; BRUN, L.; DEFRANCE, H.; SAUPHANOR, B.
Centrifugal training, based on the extinction procedure, is an innovative type of apple tree training recently used in French apple orchards. The thinning cut of fruiting spurs along the trunk and on the proximal and underside parts of the fruiting branches modifies the within-tree leaf density and light environment, which is likely to affect the development of some apple pests and pathogens. In this study, the development of the most serious foliar pests (aphids, mites) and disease (apple scab) was assessed over 3 years in an organic apple orchard with two training systems: the centrifugal training (CT) system, and the original Solaxe (OS) system, using a bent axis with no removal of fruiting spurs, as a control. Infestation levels were significantly...

Use of plants in novel approaches to control of gastrointestinal helminths in livestock with emphasis on small ruminants
Provedor de dados: 21
Autores: Githiori, John B.; Athanasiadou, S.; Thamsborg, Stig M.
Helminth infections are a major cause for reduced productivity in livestock, particularly those owned by the poor worldwide. Phytomedicine has been used for eons by farmers and traditional healers to treat parasitism and improve performance of livestock, and many modern commercial medicines are derived from plants. However, scientific evidence on the anti-parasitic efficacy of most plant products is limited regardless of their wide ethnoveterinary usage. Scientific validation of the anti-parasitic effects and possible side effects of plant products in ruminants is necessary prior to their adoption as a novel method for parasite control.     A variety of methods has been explored to validate the anthelmintic properties of such plant remedies, both in vivo...

Samtidig med at bestræbelserne på at opfinde og udbrede stadig flere alternative målestokke og måleenheder fortsætter, øges risikoen for at ende med et babelstårn af forskellige mål, måleenheder og målsætninger i (udviklings)politikken.

Inductively coupled plasma-mass spectrometry (ICP-MS) is the state-of-the-art technique for multi-elemental analysis of plant tissue. It provides a powerful tool in functional genomics, linking altered elemental profiles of mutants with gene expression and function. In addition, with its unmatched sensitivity, ICP-MS enables characterization of the substrate specificity and regulation of membrane transport proteins. Digestion of plant tissue has traditionally represented a bottleneck due to the low capacity of commercially available equipment. However, recent developments in micro-scaled digestion, combined with semi-quantitative analysis and chemometrics, have enabled high-throughput multi-elemental profiling and multivariate classification of large...

On account of the high pollen content, at the beginning of June 1996 and in May 1997 total amino acid concentrations were 53 – 390 µmol/l, in one sample 922 µmol/l. At other times the concentration in dew was 8 to 164 µmol/l. On 4 and 5 June 96 the diluted free amino acid fraction (DFAA) of the total hydrolyzed amino acids (THAA) at both sites amounted to 35 – 44% and was predominantly arginine, proline and glutamine/glutamate. Likewise on 11th  of March 97 the fraction of  DFAA was found to be 39.5% with extremely high arginine and proline fractions. At other times the...

Motive der (Nicht-)Umstellung auf Öko-Landbau
Provedor de dados: 21
Autores: Schramek, Jörg; Schnaut, Gitta.
Der Anteil der Öko-Landbaufläche in Deutschland soll nach dem Willen der Bundesregierung bis zum Jahre 2010 auf 20 Prozent der landwirtschaftlichen Fläche(LF) steigen.Um dieses ambitionierte Ziel zu erreichen, müssen die Rahmenbedingungen für den Öko-Landbau verbessert werden. Dafür sind Erkenntnisse notwendig, welche Faktoren aus Sicht der Landwirte eine Umstellung und Beibehaltung des Öko-Landbaus hemmen oder fördern.  Das Institut für Ländliche Strukturforschung (IfLS) führte hierzu im Rahmen des Bundesprogramms Ökologischer Landbau eine Untersuchung durch (Schramek und Schnaut, 2004). Ein Kernelement waren 362 persönliche Befragungen von Landwirten (sowohl konventionell als auch ökologisch wirtschaftend) im Frühjahr 2003.

Complex interplay of future climate levels of CO2, ozone and temperature on susceptibility to fungal diseases in barley
Provedor de dados: 21
Autores: Mikkelsen, B. L.; Jørgensen, R. B.; Lyngkjær, M. F.
Barley (Hordeum vulgare) was grown in different climatic environments with elevated CO2 (700 vs 385 ppm), O3 (60/90 vs 20 ppb) and temperature (24/19 vs 19/12°C day/night) as single factors and in combinations, to evaluate the impact of these climatic factors on photosynthesis and susceptibility to powdery mildew and spot blotch disease. No significant increase in net CO2 assimilation rate was observed in barley grown under elevated CO2 at ambient temperature. However, this rate was positively stimulated under elevated temperature together with a slightly higher potential quantum efficiency of PSII, both at ambient and elevated CO2, suggesting that photosynthesis was not limited by CO2 at ambient temperature. When growing under elevated temperature or O3,...

Soybean meal is an important protein input to the European livestock production, with Argentina being an important supplier. The area cultivated with soybeans is still increasing globally, and so are the number of LCAs where the production of soybean meal forms part of the product chain. In recent years there has been increasing focus on how soybean production affects the environment. The purpose of the study was to estimate the environmental consequences of soybean meal consumption using a consequential LCA approach. The functional unit is 'one kg of soybean meal produced in Argentina and delivered to Rotterdam Harbor.

The implications of phasing out conventional nutrient supply  in organic agriculture: Denmark as a case
Provedor de dados: 21
Autores: Oelofse, Myles; Jensen, L.S.; Magid, Jakob.
Soil fertility management in organic systems, regulated by the organic standards, should seek to build healthy, fertile soils and reduce reliance on external inputs. The use of nutrients from conventional sources, such as animal manures from conventional farms, is currently permitted, with restrictions, in the organic regulations. However, the reliance of organic agriculture on the conventional system is considered problematic. In light of this, the organic sector in Denmark has recently decided to gradually phase out, and ultimately ban, the use of conventional manures and straws in organic agriculture in Denmark. Core focal areas for phasing out conventional nutrients are as follows: (1) amendments to crop selection and rotations, (2) alternative...

Variations in nitrogen utilisation on conventional and organic dairy farms in Norway
Provedor de dados: 21
Autores: Koesling, Matthias; Hansen, Sissel; Bleken, Marina Azzaroli.
Reduced N-surpluses in dairy farming is a strategy to reduce the environmental pollution from this production. This study was designed to analyse the important variables influencing nitrogen (N) surplus per hectare and per unit of N in produce for dairy farms and dairy systems across 10 certified organic and 10 conventional com- mercial dairy farms in Møre og Romsdal County, Norway, between 2010 and 2012. The N-surplus per hectare was calculated as N-input (net N-purchase and inputs from biological N-fixation, atmospheric deposition and free rangeland) minus N in produce (sold milk and meat gain), and the N-surplus per unit of N-produce as net N- input divided by N in produce. On average, the organic farms produced milk and meat with lower N-surplus per...

The New Organics Logo for Europe
Provedor de dados: 21
Autores: Paull, John.
Europe has a new organics logo from 1 July 2010. The new  logo is mandated for all organic produce of Europe. The new logo is the product of a Europe-wide competition which attracted 3,422 entries, of which three were shortlisted and subjected to an internet vote. The new logo is text-free. It does not replace the plethora of certifier-specific logos currently used by Europe's certifiers, instead, it will appear in conjunction with certifier logos. When presented with this logo, half of respondents recognised the new logo as a leaf; others reported that it looked like a shooting star (17%), a fish (10%), stars (7%), other (7%), and 'don't know (10%).

Digestibility in selected rainbow trout families and modelling of growth from the specific intake of   digestible protein
Provedor de dados: 21
Autores: Rasmussen, Richard; Jokumsen, Alfred.
The experiments aimed to clarify variations in digestibility of dietary nutrients in rainbow trout. Furthermore, the objective was to study how differences in digestibility might be related to growth and feed utilisation at various growth rates.  When comparing the results from the experiments it appeared that particularly protein digestibility was closely related to specific growth rate and feed conversion ratio at high growth rates. As a tool to visualise the relationship between protein digestibility and growth of rainbow trout a growth model was developed based on the specific intake of digestible protein, and general assumptions on protein content and protein retention efficiency in rainbow trout. The model indicated that increased protein...

Effects of organic management on water-extractable organic matter and C mineralization in European arable soils
Provedor de dados: 21
Autores: Marinari, S.; Liburdi, K.; Fliessbach, A.; Kalbitz, K.
In this study we tested the hypothesis that water-extractable organic carbon (WEOC) content and its properties can be used to distinguish conventionally (CONV) from organically (ORG) managed arable soils as responsible for C mineralization. We sampled soils at three different European sites located in Mediterranean (Italy) and continental (Switzerland) regions under conventional and organic management. The Mediterranean sites are here called CVI and LSI and the continental one DOK. The main difference between the two management systems (ORG and CONV) at all sites was the amount of organic fertilizer yearly added into the soil: in the ORG systems 2.2–2.5 Mg C year−1 were added as organic fertilizer, while in the CONV systems only mineral fertilizers were...

Effects of Moringa oleifera Lam. dietary seed protein extracts on growth, nutrient utilization and blood parameters in common carp (Cyprinus carpio, L.) and Nile tilapia (Oreochromis niloticus, L.)
Provedor de dados: 21
Autores: Stadtlander, T.; Sander, C.; Kumar, V.; Makkar, H.; Becker, K.
The drumstick tree, Moringa oleifera, is a multi-purpose plant showing several beneficial effects, depending on plant part origin. The seeds for example show potential anti-biotic activity against certain pathogenic bacteria species. Furthermore they can be used for water purification since they contain specific proteins with coagulation properties. In these experiments we tested the effects of dietary M. oleifera seed protein extracts (MPE) on growth performance, nutrient utilization and blood parameters of the common carp, Cyprinus carpio, and on Nile tilapia, Oreochromis niloticus, two of the most important freshwater aquaculture fish species. The MPE was added in three concentrations (carp: 200, 400 and 600 ppm; tilapia: 400, 800 1200 ppm) to the diets...

Punch planting, flame weeding and delayed sowing to reduce intra-row weeds in row crops
Provedor de dados: 21
Autores: Rasmussen, Jesper; Henriksen, Christian Bugge; Griepentrog, Hans W.; Nielsen, Jon.
Punch planting has recently been suggested to reduce intra-row weeds in organically grown row crops. In this method holes are punched in the ground with a minimum of soil disturbance and seeds are inserted into them, without soil disturbance outside the hole. The first experiments with a tractor-mounted prototype of a dibber drill (MK III) are presented here. In two years, three plant establishment procedures were compared at five different sowing dates in sugar beet and direct-sown onion. The plant establishment procedures were 1) normal sowing and mechanical control of weeds in the stale seedbed (N), 2) N + pre-emergence flame weeding (N+F), and 3) punch planting and flame weeding to control weeds in the seedbed and prior to crop emergence (P +F).

Habitat structure versus food abundance: the importance  of sparse vegetation for the common redstart Phoenicurus  phoenicurus
Provedor de dados: 21
Autores: Martinez, Nicolas; Jenni, Lukas; Wyss, Eric; Zbinden, Niklaus.
As many other birds breeding in agricultural areas, the common redstart declined strongly in many Central European countries over the last 60 years. The destruction of traditionally managed orchards, an important breeding habitat in Central Europe, is a relevant cause. An additional factor for the decline of this species could be the intensified management of the ground vegetation in orchards through reducing food availability and lowering prey detectability and accessibility. In this study we examined the importance of surfaces with sparse vegetation for the location of redstart territories and for foraging. To validate the results of these field studies we made habitat-choice experiments in aviaries with captive birds. Territories occupied by redstarts...

Autores: Zehnder, Geoff; Gurr, Geoff M.; Kühne, Stefan; Wade, Mark R.; Wratten, Steve D.; Wyss, Eric.
Burgeoning consumer interest in organically produced foods has made organic farming one of the fastest growing segments of agriculture. This growth has not been supported adequately by rigorous research to address challenges such as arthropod pest management. The research that has been conducted, however, is complemented by research in aspects of conventional agriculture that may have applicability in organic systems, as well as by research in underpinning ﬁelds such as applied ecology. This article synthesizes the available literature in relation to a conceptual model of arthropod pest management strategies suitable for organic systems. The present work uses the four phases of the model to review the strategies in an agroecological context and provides a...

The impact of organic certification and country of origin on consumer food choice in developed and emerging economies
Provedor de dados: 21
Autores: Thøgersen, John; Pedersen, Susanne; Aschemann-Witzel, Jessica.
The effects of organics and country of origin (COO) on consumers’ food choices have mostly been investigated separately. In order to investigate the joint effect of these two credence quality cues and when they influence choice, a choice-based conjoint (CBC) experiment was conducted in Germany, France, Denmark, China and Thailand. In each country, a sample of about 1000 consumers participated after being screened for responsibility for their household’s shopping, consumption of the case product, and knowledge of organic food. A full factorial design with four COOs, three different organic label conditions and three price levels gave 36 different choice options. They were bundled in 12 choice sets of three alternatives, which were presented in random order....

Negative effects of low developmental temperatures on aphid predation by Orius majusculus (Heteroptera: Anthocoridae)
Provedor de dados: 21
Autores: Helgadóttir, Friða.
Biological control agents (BCA) are often mass reared at conditions very different from those at which they have to provide their service, especially if they are to be used under field conditions. It has been suggested that biocontrol efficiency might be enhanced by acclimating the BCA under near-field conditions for some time before release (beneficial acclimation hypothesis), and some studies (e.g. with ladybirds) have supported this idea. We reared Orius majusculus, a commercially available BCA, at three temperatures (12, 16 and 20 °C) throughout the whole development. The predation capacity for rosy apple aphids (Dysaphis plantaginea) of females from each of these treatments was tested at the same temperatures (12, 16 and 20 °C). Additionally, we...

„Der ökologische Landbau wirtschaftet naturnah!“ Dieses Schlagwort wird gerne verwendet, wenn der Öko-Landbau aus Naturschutzsicht zu bewerten ist. In der Abgrenzung zur konventionellen Landbewirtschaftung stimmt dies natürlich: Viele Vergleichsuntersuchungen  belegen einen schonenderen Umgang mit der unbelebten Umwelt und höhere Artenvielfalt auf Bio-Betrieben – ein im Grunde banales Ergebnis, auch wenn es im Einzelfall noch Forschungsbedarf gibt. Doch auch im Öko-Landbau lassen frühe Schnittzeitpunkte zur Silagegewinnung, hohe Mahdfrequenz und tiefer Schnitt sowie hohe Besatzdichten und Portionsweiden die biologische Vielfalt von Wiesen verarmen.

Increasing plant diversity in grasslands may improve productivity and yield stability. This study investigates in a field experiment, yield and quality of two-species swards of ryegrass/white clover and three-species swards of ryegrass/white and red clover at five different managements representing cutting, grazing, combinations of cutting and grazing and different fertilizer treatments in 1 to 4-yr-old swards. Generally, the three-species mixture produced higher yields than the two-species mixture when swards were young and lower yields when swards were 3 and 4 years old. Fertilizer responses were similar in both mixtures and also rather independent of sward age. The overall mean annual yield increase by slurry application was 1.34 t DM corresponding to...

Controlling reproduction in organic sheep breeding: the influence of breeding factors on the effectiveness of the ram effect
Provedor de dados: 21
Autores: TOURNADRE, H.; PELLICER, M.; BOCQUIER, F.
The ram effect, which is a natural method for the control of reproduction in sheep, is an alternative to hormone treatments that are banned on organic farms. The ram effect induces a combination of ovulation and oestrus in ewes that is acyclic and conducive to artificial insemination. The proportion of acyclic females with induced ovulation and their subsequent fertility at the first oestrus is variable. The control of some breeding factors that have been studied here may help to reduce this variability. The proportion of ewes induced to ovulate by rams increased as the season advanced (54% in April vs. 84% at the end of May, p&lt;0.05) and with a longer time period between drying-off and mating: from 29% to 84% (p&lt;0.001) for 22 and 86 days elapsed,...

Early maize root and phosphorus uptake responses to localised application of sewage sludge derived fertilisers
Provedor de dados: 21
Autores: Lemming, Camilla; Oberson, Astrid; Hund, Andreas; Stoumann Jensen, Lars; Magid, Jakob.
Background: Phosphorus recycling from waste and localised placement of fertilisers can be means to improve sustainable P management in agriculture. However, knowledge about root and plant P uptake responses to placement of complex waste- derived fertilisers is lacking.  Methods: Sewage sludge (SS) and sewage sludge ash (ASH) were tested against triple superphosphate (TSP) in a rhizobox setup where shoot and root growth of maize was followed for 30 days. The three P sources were either mixed homogenously into the soil (labelled with 33P) or localised in a patch close to the seed.  Results: While localised TSP and SS both increased root length density around the fertiliser patch, it was at the expense of the remaining root system and soil P uptake for SS....

Acting against common bunt: exploration of various control methods
Provedor de dados: 21
Autores: Fontaine, Laurence; Robin, N.; Bruyère, J.; du CHEYRON, P.
Common bunt (Tilletia caries, Tilletia foetida) is a fungal disease with a large ability to spread. Consequences may be rejection of grains for sale or even a large decrease of yield. Different trials were carried out in organic farming in a research project (funded by the French Ministry of Agriculture between 2008 and 2011) to achieve a better control of common bunt. Results confirm that the resistance of wheat cultivars is a factor to consider. Despite most varieties currently cultivated in organic farming are sensitive to common bunt, some cultivars appeared to be resistant to the races tested. Concerning seed treatment, no product is available for organic farming and 100% efficient; but several solutions have been identified. Only one product is...

Organic vine growing: from breaking new ground to bringing back the taste of the terroir
Provedor de dados: 21
Autores: TEIL, G.; BARREY, S.
Organic farming certification has certainly contributed to unifying organic production, particularly by reducing the number of private charters. However, this reduction should not be misleading. Organic agriculture cannot be reduced to just a label and includes other requirements related to ethics, agronomy and economic policy whose implementation contributes to the diversification of marketing organisations that selectively ensure the marketing of organic products. Furthermore, in the case of viticulture, organic producers have recently placed more emphasis on the taste quality of their wines that they have linked in various ways to the quality of the environment. This new link between taste and environment has added a new complexity to marketing...

Autores: Bellostas, Natalia; Kachlicki, Piotr; Sørensen, Jens Christian; Sørensen, Hilmer.
Consumption of Brassica vegetables is related to a decreased incidence of certain cancer forms, and it has been linked to the presence of glucosinolates in these vegetables. After ripe seeds, Brassica sprouts contain the highest concentration of these compounds and are therefore a good source of glucosinolates for chemoprotection. In the present experiments, the content and distribution of glucosinolates in five varieties of B. oleracea (white cabbage, red cabbage, Savoy cabbage, broccoli and cauliflower) was determined in ripe seeds and sprouts of up to seven days by High Performance Liquid Chromatography. The type and concentration of individual glucosinolates varied according to B. oleracea variety, plant part and length of the sprouting period....

Autores: Izquierdo-Lopez, Maria Dolores; von Davier, Zazie; Deblitz, Claus.
The main objective of the project presented in this article was to analyse the strengths and weaknesses of German organic beef production as compared with France, Austria, the Czech Republic and Argentina. Additionally, a number of marketing initiatives in France, Austria, Great Britain and Switzerland were analysed to examine their applicability to German conditions.  Within the framework of the International Farm Comparison Network, eleven case studies of organic beef farms in the countries considered were analysed. The strength of the German farms lies on the return side, which is dominated by direct payments. Germany and Austria produce at the highest cost, and profitability in Germany is relatively low. Competitive pressure from France and Austria can...

Autores: Gravador, Rufielyn S.; Jongberg, Sisse; Andersen, Mogens L.; Luciano, Giuseppe; Priolo, Alessandro; Lund, Marianne N.
The antioxidant effects of dried citrus pulp on proteins in lamb meat, when used as a replacement of concentrate in the feed, was studied using meat from 26 male Comisana lambs. The lambs of age 90 days had been grouped randomly to receive one of the three dietary treatments: (1) commercial concentrate with 60% barley (Control, n = 8), (2) concentrate with 35% barley and 24% citrus pulp (Cp24, n = 9), or (3) concentrate with 23% barley and 35% citrus pulp (Cp35, n = 9). Slices from the longissimus thoracis et lomborum muscle were packed aerobically and stored for up to 6 days at 4°C in the dark. The citrus pulp groups, Cp24 and Cp35, significantly decreased protein radicals and carbonyls, and preserved more thiols within six days of storage compared to the...

Autores: Bennedsgaard, Torben Werner; Thamsborg, Stig Milan; Aarestrup, Frank Møller; Enevoldsen, Carsten; Vaarst, Mette; Christoffersen, Anna Bodil.
Quarter milk samples from cows with high risk of intramammary infection were examined to determine the prevalence of Staphylococcus aureus (SA) and penicillin resistant SA (SAr) in conventional and organic dairy herds and herds converting to organic farming in a combined longitudinal and cross-sectional study. 20 conventional herds, 18 organic herds that converted before 1995, and 19 herds converting to organic farming in 1999 or 2000 were included in the study. Herds converting to organic farming were sampled three times one year apart; the other herds were sampled once. Risk of infection was estimated based on somatic cell count, milk production, breed, age and lactation stage. The high-risk cows represented about 49 % of the cows in the herds. The...

Development of automated tools based on electronic identification for the improvement of organic livestock production systems
Provedor de dados: 21
Autores: MATON, C.; MONTAGNAC, D.; VIUDES, G.; BOUCQUET, P.; BOCQUIER, F.
Technical constraints of livestock production in organic farming systems are numerous and require more attention than in conventional systems. The implementation of individual electronic identification that is planned in Europe offers the possibility of developing automated devices that may be well adapted to the practices of organic breeders. We developed an automated mounting detector, carried by a male, which makes it possible to detect any female in oestrus. Hence, this device is the unique solution for inseminating females when they are fertile, thus ensuring links with selection programmes. The second  device developed is a dynamic sorting door based on respect for animal behaviour, preventing stress by allowing animals not to be unnecessarily...

Consumers’ purchase of organic food products. A matter of convenience and reflexive practices
Provedor de dados: 21
Autores: Hjelmar, Ulf.
The aim of this study was to gain insight into the purchase of organic food products by consumers and to explore the main factors driving this process. This paper uses evidence from 16 in-depth interviews with consumers in Denmark carried out in 2008–2009. On the basis of the analysis two broad concepts are suggested: convenience behaviours and reflexive practices. Convenience behaviours are characteristic of pragmatic organic consumers. This type of shopping behaviour requires organic foods to be available in the local supermarket, they have to be clearly visible (preferably with an eco-label), and the price differential vis-à-vis conventional products have to be minimal. The analysis also showed that politically/ethically minded consumers have reflexive...

PART I: SHORT HISTORY OF ORGANIC FARMING  The organic fruit production in Europe is not only a matter of statistics, regulations and tables but also has a meaningful historical background. So as an introduction, we can take a brief excursion back to the roots and the evolution of organic farming. (The following text is closely—but not entirely—based on an overview article of Gunter Vogt, 2000a). Organic farming’s origins in the first decades of the 20th century need to be understood in the context of five main aspects:

Organic agriculture in Cuba: The revolution goes green
Provedor de dados: 21
Autores: Kilcher, Lukas.
Agriculture in post-revolutionary Cuba is based on large-scale, capital-intensive and labour-extensive monocultures. In order to sustain these, the island continually imported fertilizers, pesticides and diesel at subsidized prices from the former Soviet economic aid community, COMECOM. Since this collapsed in the early 1990s, Cuba has suffered from an acute shortage of raw materials. At the same time, the main sales market for Cuban agricultural production has disappeared. Given this situation, agriculture in Cuba faces multiple challenges: Firstly Cuba needs to find new customers, practically overnight. Secondly, its agricultural producers must learn to manage with the little that they themselves have. Thirdly, Cuba needs financial resources to renovate...

Provedor de dados: 21
Autores: Luka, Henryk; Marggi, Werner; Nagel, Peter.
The species Agonum nigrum DEJEAN, 1828, rare in central Europe, is reported for the first time from Switzerland. A distribution map is provided, based on reviewed specimens from museum collections and on literature data. Agonum nigrum is a Mediterranean species with a core distribution in southern Europe. The Swiss locality is situated on the upper Rhine near Basel in an area of meadows and light forest, which has been strongly shaped by man. The habitat is characterized by regular artificial inundation for ground water supply. The characters distinguishing A. nigrum from the similar Agomun atratum (DUFTSCHMID, 1812) are critically examined, and corrected or supplemented when neccssary.

A universal simulator for ecological models
Provedor de dados: 21
Autores: Holst, Niels.
To most modellers, ecological models are primarily about ecology. A model is a condensed summary of an ecosystem written in the language of mathematics and logic. While modellers with a mathematical inclination may prefer stringent model formulations, that allow formal mathematical analysis, most modellers in ecology prefer heterogeneus, composite models permitting only numerical analysis; they are computational modellers who implement their models in software, which then itself becomes both tool and object in the ensuing analysis. The design and implementation details of this software is largely neglected. But this paper is only about this: the proper design and implementaion of ecological models.

Concentrations of soil potassium after long-term organic dairy production
Provedor de dados: 21
Autores: Løes, Anne-Kristin; Øgaard, Anne Falk.
On five long-term organic dairy farms aiming at self-sufficiency with nutrients, soil concentrations of ammonium-acetate lactate extractable potassium (K-AL) and acid-soluble K was measured twice in topsoil (0-20 cm) and subsoil (20-40 cm) over periods of 6-14 years. Organic management had occurred for &gt;9 years at the second sampling. On average there were most probably field level K-deficits. Even so, topsoil K-AL concentrations were medium high (65-155 mg K kg–1 soil), and did not decrease during the study period. However, for three farms, topsoil K-AL was approaching a minimum level determined by soil texture, where further decrease is slow. Subsoil K-AL concentrations were generally low (&lt;65). The soils were mostly light-textured, and reserves of...

‘Organic farming’ in Denmark: Enhancement or dissolution? A survey among organic farmers
Provedor de dados: 21
Autores: Noe, Egon.
The Danish organic farmers’ strategy of strategic cooperation with actors of the conventional food production chains is widely seen as a success story, not least in terms of volume and efficiency. On the other hand it has been claimed that this strategy would easily lead to a dissolution of the network forces that produce and reproduce the ideas and values of organic farming and thereby the forces that are developing the organic farming practice. The objective of this paper is to re-examine the surveys among the Danish organic farmers, conducted by Michelsen and his colleagues to examine whether the process we are witnessing is a process of enhancement or dissolution of ‘Organic farming’. Michelsen finds a minor difference in attitudes toward organic and...

A modernização da agricultura alterou suas relações com o restante da economia. As mudanças na base técnica e as políticas agrícolas determinaram a necessidade de crescimento das escalas mínimas viáveis do ponto de vista técnico e econômico, promovendo um processo de seleção e exclusão entre os pequenos produtores rurais, sem no entanto implicar na eliminação da pequena produção familiar.

Differences in the Morphological Characteristics of the Land Races of the Soft and Emmer Wheat in Relation to the Modern Varieties
Provedor de dados: 21
Autores: Konvalina, Petr; Stehno, Zdenek; Capouchova, Ivana; Moudry, Jan; Sramek, J.; Moudry, Jan (Jr.).
For the organic farmers there is important question which varieties of wheat are right for organic farming in Less Favoured Areas. Modern varieties of wheat are bred in the conditions of conventional (high imput) farming. That is why the organic farmers asked about the suitability of land  races of soft wheat (Triticum aestivum L.) or different species like emmer wheat grown in the past (Triticum dicoccum SCHUEBL). The paper results from the study of fourty land races, two intermediate and ten modern varieties of soft wheat in comparison to ten land races of emmer wheat at two locations in the Czech Republic. We evaluated tuft shape, length of plant, length and width of flag leaf, length and density of spike and awnedness. The  modern varieties of soft...

Qualité de la viande d’agneau de quatre races ovines suisses
Provedor de dados: 21
Autores: Heckendorn, Felix; Leiber, Florian; Probst, Johanna.
La qualité de la viande des agneaux de boucherie dépend d’un grand nombre de facteurs. Outre l’âge au moment de l’abattage et le sexe, l’affouragement a une incidence prépondérante. En principe, un affouragement constitué principalement de céréales, comparé à du fourrage plutôt grossier, provoque les plus grandes différences dans la qualité de la viande. Une autre influence très discutée sur la qualité de la viande est la race; on dit que les races primitives comme le Heidschnucke ont une qualité de viande élevée, se rapprochant de celle du gibier.  Certaines races primitives suisses ont également la réputation d’avoir une viande particulièrement bonne.

The effect of sowing date, stale seedbed, row width and mechanical weed control on weeds and yields of organic winter wheat
Provedor de dados: 21
Autores: Rasmussen, Ilse A.
Three field experiments were carried out in organically grown winter wheat in Denmark. The treatments were sowing time (normal or late sowing) and false seedbed, row width (12 cm and 24 cm) and weed control method (untreated, mechanical weed control (weed harrowing at 12 cm supplemented with inter-row hoeing at 24 cm), and herbicide weed control). Weed biomass in mid-summer was greatest on plots sown at the normal sowing time (compared to delayed sowing) and was reduced by mechanical or chemical weed control (compared with untreated plots). Row width alone had no influence on weed biomass, but in the experiment with high weed pressure, the more intensive mechanical weed control used at a row width of 24 cm reduced weed biomass. Normal sowing time tended to...

Quest for sustainability in the Indian tea industry starts on a serious note in the backdrop of several key issues such as impact of climate change on crop productivity, higher intensity of pest and diseases, rampant use of agrochemicals, issue of pesticide residues, increasing mandays cost etc. In this difficult time when most of the tea producers are looking for areas for cost curtailment, Goodricke Group Ltd., initiated the Sustainable Management Programme with the objectivity of producing sustainable teas with low pesticide footprint from the year 2014 onwards. The present study was conducted as a part of the above programme, to evaluate the effectiveness of on-farm generated compost towards soil microbial enrichment.  Large-scale composting was done...

Abatement costs for agricultural nitrogen and phosphorus loads: a case study of crop farming in south-western Finland
Provedor de dados: 21
Autores: Helin, Janne; Laukkanen, Marita; Koikkalainen, Kauko.
Designing efficient agri-environmental policies for agricultural nutrient load reductions calls for information on the costs of emission reduction measures. This study develops an empirical framework for estimating abatement costs for nutrient loading from agricultural land. Nitrogen abatement costs and the phosphorus load reductions associated with nitrogen abatement are derived for crop farming in south-western Finland. The model is used to evaluate the effect of the Common Agricultural Policy reform currently underway on nutrient abatement costs. Results indicate that an efficiently designed policy aimed at a 50% reduction in agricultural nitrogen load would cost € 48 to € 35 million, or € 3756 to € 2752 per farm.

Sustainable bioethanol production combining biorefinery  principles using combined raw materials from wheat undersown with clover-grass
Provedor de dados: 21
Autores: Thomsen, Mette Hedegaard; Hauggaard-Nielsen, Henrik.
To obtain the best possible net energy balance of the bioethanol production the biomass raw materials used need to be produced with limited use of non-renewable fossil fuels. Intercropping strategies are known to maximize growth and productivity by including more than one species in the crop stand, very often with legumes as one of the components. In the present study clover-grass is undersown in a traditional wheat crop. Thereby, it is possible to increase input of symbiotic fixation of atmospheric nitrogen into the cropping systems and reduce the need for fertilizer applications. Furthermore, when using such wheat and clover-grass mixtures as raw material, addition of urea and other fermentation nutrients produced from fossil fuels can be reduced in the...

Autores: Vauhkonen, Ville; Lauhanen, Risto; Ventelä, Sarita; Suojaranta, Juhani; Pasila, Antti; Kuokkanen, Toivo; Prokkola, Hanna; Syväjärvi, Sanna.
The aims of this study were to determine the phytotoxicity of stored rapeseed (Brassica rapa) oil (RSO) and rapeseed oil methyl ester (RME) after "spill like" contamination on the growth of barley (Hordeum vulgare) and the biodegradability of these substances in OECD 301F test conditions and in ground water. Rapeseed oil and rapeseed oil methyl ester were both stored for a period of time and their fuel characteristics (e.g. acid number) had changed from those set by the fuel standards and are considered to have an effect on its biodegradation. The phytotoxicity was tested using two different types of barley cultivars: ‘Saana’ and ‘Vilde’. The phytotoxic effect on the barley varieties was determined, after the growth season, by measuring the total biomass...

Bioproduction in the Czech Republic
Provedor de dados: 21
Autores: Moudry, Jan (Jr.); Konvalina, Petr; Kolarova, Pavlina.
Organic farming in the Czech Republic is particularly located in Less Favoured Areas (LFA), which are often overlaid with environmentally sensitive areas. Acreage of organic farming in the Czech republic makes about 6% of the whole agriculture land. At present acreage of organic farming is 281 535 ha. More than 90% share of this acreage represent grasslands. Grasslands are linked with non-milk cattle breeding. Organic farming fulfils its environmental function good in contrast to its production function which is fulfilled much less. As the main product of organic farming in Czech Republic is produced bee, but most of this beef isn’t certified as a bio-product. The amount of bio-products is not sufficient enough and does not cover both market and export...

Autores: Mejer, Helena; Roepstorff, Allan.
SUMMARY  Transmission of Oesophagostomum dentatum and Trichuris suis was studied in outdoor reared pigs. Six farrowing paddocks were naturally contaminated in May to mid June 2001 by experimentally infected seeder pigs. Early July, 1 sow farrowed on each paddock and starting week 3 post partum (p.p.) the offspring was slaughtered serially every 2 weeks for recovery of O. dentatum and T. suis. Faeces was collected regularly for parasite egg counts and acid-insoluble ash (AIA) content as an indicator for geophagy. Weaning took place week 7 p.p. by removing the sow. Paddock infection levels were estimated in mid June (O. dentatum) and late November (O. dentatum and T. suis) using helminth naïve tracer pigs. Soil and vegetation samples were collected...

Environmental assessment of organic soybean (Glycine max.) imported from China to Denmark: a case study
Provedor de dados: 21
Autores: Knudsen, Marie Trydeman; Yu Hui, Qiao; Yan, Luo; Halberg, Niels.
Growing global trade with organic products has increased the demand for environmental impact assessments during both production and transport. Environmental hotspots of organic soybeans produced in China and imported to Denmark were identified in a case study using a life cycle assessment  approach. Furthermore, environmental impacts of organic and conventional soybeans at farm gate were compared in the case study. The total global warming potential (GWP) per ton organic soybeans imported to Denmark revealed that 51% came from transportation and 35% from the farm level.  Comparing organic and conventional soybean at farm gate showed that GWP, non-renewable energy use, acidification and eutrophication was lower per ton organic soybeans, whereas land use was...

Buffers for biomass production in temperate European agriculture: A review and synthesis on function, ecosystem services and implementation
Provedor de dados: 21
Autores: Christen, Ben; Dalgaard, Tommy.
In addition to their potential for biomass production, buffer strips on agricultural land have been shown to protect surface water quality by reducing erosion and nutrient leaching, and can play a key role in nature and flood protection, and the design of bioenergy landscapes resilient to climate changes, and the environmental pressures from intensive agriculture. Use of conservation buffers by farmers outside of designated schemes is very limited to date, but the increasing demand for bioenergy and the combination of agricultural production with nature protection calls for a much wider implementation. This paper reviews the knowledge on buffer functioning, socioeconomics and practical farming aspects. It describes how a defined three-zone buffer design,...

A nonparametric characteristics model of the demand for milk
Provedor de dados: 21
Autores: Andersen, Laura M.; Blow, Laura; Browning, Martin; Crawford, Ian.
Characteristics models in demand analysis capture the idea that people value goods not For the commodity itself but for the characteristics (or attributes) or embodied in the good. For example, agents may care about the fat content and the taste of different sorts of milk but not the actual type of milk. When we have fewer characteristics than types of good the theory imposes restrictions on observables. We present a revealed preference characteristics model analysis of the demand for milk in Denmark.

The relationship between agriculture and nature is a central issue in the current agricultural debate. Organic Farming has ambitions and a special potential in relation to nature. Consideration for nature is part of the guiding principals of organic farming and many organic farmers are committed to protecting natural qualities. However, the issue of nature, landscape, and land use is not straightforward. Nature is an ambiguous concept that involves multiple interests and actors reaching far beyond farmers. The Danish research project Nature Quality in Organic Farming has investigated the relationship between nature and organic farming.

Physical destruction of the sprouting ability of Elytrigia  repens rhizome buds
Provedor de dados: 21
Autores: Melander, B.; Kristensen, J.K.; Kristensen, K.; Mathiassen, S.K.; Nørremark, M.; Kristensen , E.F.
Traditional strategies for controlling Elytrigia repens infestations in organic cropping in Scandinavia are based on repeated post-harvest cultivation. However, post-harvest tillage is undesirable due to the need for retaining nutrients in the cropping systems. There is a need to look  for solutions where E. repens can be controlled over a short duration to allow replanting of the soil.  A Danish project is investigating new technologies that can meet such requirements. One aspect is to look for methods that physically can destruct the sprouting ability of E. repens rhizome buds. We investigated the effect of heating using hot water and mechanical crushing by pressure on the  sprouting ability of exposed rhizome buds. The effect of temperatures &lt; 70oC...

Recovery and characterisation of DNA from virgin olive oil
Provedor de dados: 21
Autores: Muzzalupo, PhD Innocenzo; Perri, Dr Enzo.
The characterisation of the genetic identity of DNA recoverable from olive oil could facilitate the assessment of its place of origin and conformity to type thanks to the particular regional spread of olive cultivars and to their different contributions to the olive oil mixture as stated by each Protected Designation of Origin regulation. This requires that intact DNA should be recovered from virgin olive oil. In an attempt to recover DNA from virgin olive oil, the performance of three different oil production methods was compared. The recorded data demonstrate that only olive oil obtained by using proteinase K treatment during the malaxation process contains DNA amenable to random amplified polymorphic DNA (RAPD)-PCR amplification.

Land sharing vs. land sparing for biodiversity: How agricultural markets make the difference
Provedor de dados: 21
Autores: Desquilbet, Marion; Dorin , B.; Couvet, D.
We show that the most interesting type of farming for biodiversity depends on the equilibrium on agricultural markets. All other things being equal, when demand reacts to prices and when extensive farming has higher production costs, this type of farming may allow a higher level of biodiversity than intensive farming if the relation between biodiversity and yield does not have a very high degree of convexity. This extensive farming is detrimental to consumers when their surplus is evaluated restrictively as increasing with quantities consumed and decreasing with higher prices. Its effect on agricultural producers is indeterminate. It does not have a simple effect on food security.

Forskning er en modsætning til økologernes intuitive erkendelsesproces. Og det gælder både videnskab, der forsøger at atomisere verden i forklaringsprocessen, hvor sammenhænge og placering reduceres væk til fordel for detaljeret beskrivelse af delemnerne, og i systemanalysen, hvor fokus er på sammenhænge, men hvor delene reduceres væk. Forskningen har sin styrke ved at kunne teste hypoteser, men har sin svaghed ved at have problemer med at skabe relevante hypoteser og ved at gøre testresultaterne anvendelige (generaliserbare). Intuitionen derimod er holistisk i den forstand, at den forsøger at inddrage alt, og den er god til at skabe hypoteser og vurdere resultater, men har sin svaghed ved ikke at kunne dokumentere dem.

Communities of arbuscular mycorrhizal fungi (AMF) are strongly affected by land use intensity and soil type. The impact of tillage practices on AMF communities is still poorly understood, especially in organic farming systems. Our objective was to investigate the impact of soil cultivation on AMF communities in organically managed clay soils of a long-term field experiment located in the Sissle valley (Frick, Switzerland) where two different tillage (reduced and conventional mouldboard plough tillage) and two different types of fertilization (farmyard manure &amp; slurry, or slurry only) have been applied since 2002. In addition, a permanent grassland and two conventionally managed croplands situated in the neighborhood of the experiment were analyzed as...

Most horticultural crops are attacked by more than one insect pest. As broad-spectrum chemical control options  are becoming increasingly restricted, there is a need to develop novel control methods. Semiochemical attractants  are available for three important horticultural pests, strawberry blossom weevil, Anthonomus rubi Herbst  (Coleoptera: Curculionidae), European tarnished plant bug, Lygus rugulipennis Poppius (Hemiptera: Miridae) and  raspberry beetle, Byturus tomentosus deGeer (Coleoptera: Byturidae). Traps targeting more than one pest species  would be more practical and economical for both monitoring and mass trapping than traps for single-species.

Modelling diverse root density dynamics and deep nitrogen uptake
Provedor de dados: 21
Autores: Pedersen, Anders; Zhang, Kefeng; Thorup-Kristensen, Kristian; Jensen, Lars Stoumann.
We present a 2-D model for simulation of root density and plant nitrogen (N) uptake for crops grown in agricultural systems, based on a modification of the root density equation originally proposed by Gerwitz and Page (1974). A root system form parameter was introduced to describe the distribution of root length vertically and horizontally in the soil profile. The form parameter can vary from 0 where root density is evenly distributed through the soil profile, to 8 where practically all roots are found near the surface. The root model has other components describing root features, such as specific root length and plant N uptake kinetics. The same approach is used to distribute root length horizontally, allowing simulation of root growth and plant N uptake...

Experiences in Transplanting Wood Ants into Plantations for Integrated Pest Management
Provedor de dados: 21
Autores: Nielsen, J.S.; Nielsen, M.G.; Offenberg, J.
Ants can function efficiently as biocontrol agents in open field horticulture. Temperate wood ants can control forest pests, including species damaging forest regeneration plots and fruit plantations. Thus, they possess potential as biocontrol agents in open field horticulture, if they can persist in these systems. Here we present observations on activity and survival of wood ants transplanted from forests into different types of plantations. Mound fragments were transplanted into a conifer seedling plot, an organic and a conventional Christmas tree plantation, and into an organic apple plantation. Colonies survived at least one year in all types of plantations. In some cases, however, ants moved to new locations or migrated between mound fragments,...

Autores: Kidmose, Ulla; Jensen , sidsel; Mejnertsen, Peter; Jørgensen, Johannes Ravn; Thorup-Kristensen, Kristian.
Five different wheat cultivars (Thifun, Triso, Thasos, Spelt and Emmer) were cultivated in an organic study using six different organic compost types (two different household waste composts, sewage sludge compost, fruit and vegetable compost and two different renescience compost types) and one control with no manure applied. Bread was baked with flour from each of the samples. The protein content, the gluten content and the falling number were measured for the flour samples and specific volume, the sensory quality and instrumental measured hardness were measured on the bread samples. Different compost types resulted in distinct different sensory profiles of the bread. However, the tested cultivars responded very different towards the different compost...

Hvad forstås ved begrebet jordens frugtbarhed
Provedor de dados: 21
Autores: Christensen, Bent T.
Jordens frugtbarhed afhænger af et komplekst samspil mellem naturgivne og menneskeskabte forhold. En karakterisering af jordens frugtbarhed kræver bestemmelse af flere nøgleparametres udvikling over tid. Begrebet jordens frugtbarhed kan meningsfyldt defineres som jordens evne til vedvarende at understøtte en landbrugsmæssig planteproduktion, der er forsvarlig med hensyn til omfang, kvalitet, rentabilitet og påvirkning af det omgivende miljø. Jordens frugtbarhed vil således være påvirket af driftsform og planteproduktionens teknologiske og økonomiske rammer.

Organic seed treatment to control common bunt (Tilletia tritici) in wheat
Provedor de dados: 21
Autores: Borgen, Anders.
Common bunt caused by the fungus Tilletia tritici (syn. T.caries) is one of the most devastating plant diseases in wheat. In conventional agriculture the disease is controlled exclusively by fungicide seed treatment, but in organic farming these fungicides are not accepted. Previous studies in India have shown that seed treatment with plant extracts of Canabis sativa, Eucalyptus globulus, Thuja sinensis and Datura stramonium was fully effective against the disease under field conditions. Later, in vitro studies have shown that also germination of spores of the Karnal bunt pathogen (Neovossia indica) could be prevented by these plant extracts. The experiment was repeated in Denmark with extracts from the same species grown in Denmark, which has climate...

Community supported agriculture in urban settings. A way for better understanding and complementation of sustainability - a Norwegian experience.
Provedor de dados: 21
Autores: Friis Pedersen, Susanne.
Norway covers an abundant wilderness, only 3 % of the land are cultivated. Population is scarce many places of the country, but like trends elsewhere, there are a concentration towards more urban settings. Urban citizens take action for future sustainable development through producing some of their own food. Politics protect land resources for agriculture, but agricultural areas are still decreasing. The official goal of 15 % production and market shares of organic products in 2020 can stimulate urban farming.     Literature states how people carries out top goals for sustainability in a humble practical approach.       The eagerness to grow food is underlined by the growth of community supported agriculture (CSA) from a single one in 2006 to more than 50...

PREMISE OF THE STUDY:  Despite long-term research efforts, a comprehensive perspective on the ecological and functional properties determining plant weediness is still lacking. We investigated here key functional attributes of arable weeds compared to non-weed plants, at large spatial scale.  METHODS:  We used an intensive survey of plant communities in cultivated and non-cultivated habitats to define a pool of plants occurring in arable fields (weeds) and one of plants occurring only in open non-arable habitats (non-weeds) in France. We compared the two pools based on nine functional traits and three functional spaces (LHS, reproductive and resource requirement hypervolumes). Within the weed pool, we quantified the trait variation of weeds along a...

Information search behaviour and its determinants: the case of ethical attributes of organic food
Provedor de dados: 21
Autores: Zander, Katrin; Hamm, Ulrich.
Daily decisions on food purchase are known to be undertaken using limited information search. However, when confronted with ‘ethical’ products, consumers often become more involved, and this results in a more extensive search for information. This research focuses on the information search behaviour of European consumers with regard to ethical attributes, like animal welfare or environmental aspects of organic food by means of an Information Display Matrix. Row-wise information search by product characteristics (attributes) was widely preferred over information search by product alternatives (column-wise). Therefore information e.g. in the internet should increasingly be provided by attributes. The majority of consumers use simplifying and selective search...

This study investigated the effect of replacing cereal concentrateswith high levels of dried citrus pulp in the diet on lamb meat oxidative stability. Over 56 days, lambs were fed a barley-based concentrate (Control) or concentrates inwhich 24% and 35% dried citrus pulpwere included to partially replace barley (Citrus 24% and Citrus 35%, respectively). Meat was aged under vacuum for 4 days and subsequently stored aerobically at 4 °C. The Control diet increased the redness, yellowness and saturation of meat after blooming (P &lt; 0.01). Regardless of the level of supplementation, dietary dried citrus pulp strongly reduced meat lipid oxidation over 6 days of aerobic storage (P &lt; 0.001), while colour parameters did not change noticeably over storage and...

Intercropping leek (Allium porrum L.) with dyer’s woad (Isatis tinctoria L.) increases rooted zone and agro-ecosystem retention of nitrogen.
Provedor de dados: 21
Autores: Xie, Yue; Kristensen, Hanne Lakkenborg.
Nitrate leaching can be high in organic vegetable production. Late-harvested crops like leek limit the use of autumn catch crops. The aim of this study was to investigate the growing of a combination of a deep-rooted catch crop and a shallow-rooted vegetable to reduce the risk of nitrate leaching. We compared a leek sole crop (S) with two intercropped systems of leek and early-sown dyer’s woad (five weeks after leek planting) (IE) or late-sown dyer’s woad (eight weeks after leek planting) (IL) in two seasons: 2012 and 2013. To reveal root and resource competition, leek with dyer’s woad rows left empty (Semp), and early and late-sown dyer’s woad with leek rows left empty (DEemp, DLemp) were included.

Autores: Katakam, Kiran Kumar; Thamsborg, Stig Milan; Kyvsgaard, Niels Christian; Dalsgaard, Anders; Mejer, Helena.
Indoor transmission of Ascaris suum partly depends on the physico-chemical conditions in bedding material. Temperature,pH, aqueous ammonia, moisture, occurrence and development of A. suum eggs were therefore compared in different areas(resting, intermediate and latrine) of two deep litter pens on an organic farm in four seasons. There was some variation, but mean ammonia levels were generally very low (1·0–2·6mM) and pH levels were moderate (8·04–8·88) in all three areas. Relatively, resting areas were characterized by overall moderate moisture (36%) and moderately high temperature (35·7 °C)levels. The area contained few eggs (50 eggs g−1 DM) of which 17% were viable, and though only 4% were larvated and 0·7% appeared infective, it was more than in the...

Biogas in organic agriculture - effects on productivity, energy self-sufficiency and greenhouse gas emissions
Provedor de dados: 21
Autores: Pugesgaard, Siri; Olesen, Jørgen E.; Dalgaard, Tommy; Jørgensen, Uffe.
Reduction in the dependency on fossil fuels has been  identified as one of the important areas for development of organic farming in Denmark (ICROFS, 2008). The increased public awareness on the need for actions against global warming has brought Green House Gas (GHG) emissions and the use of fossil fuels into focus in the agricultural organisations in general as well as in the organic agricultural organisations.      Several scenarios for biogas production in organic agriculture could be imagined. The implementation of biogas production on organic farms and the effect of this implementation depend on the existing farming system, how the implementation is done and how this changes the farming system. Therefore the aim of this paper is to focus specifically...

To understand how earthworms could improve soil porosity in no-tillage organic farming systems, the aim of our study was to compare the effect of different tillage systems on earthworm populations, from conventional (traditional mouldboard ploughing, MP and shallow mouldboard ploughing, SMP) to conservation tillage (reduced tillage, RT, direct drilling or very superficial tillage, NT) in three organic arable systems in France (sites A–C). In a second stage, the effect of earthworm activity on soil porosity under the four tillage systems was assessed at sites A and B. Earthworm abundance, biomass and diversity were measured over a 2–3-year period at the 3 sites. During the same period, soil structure (soil profile description and soil bulk density) and open...

Ethvert husdyr og enhver kulturplante tager et lille bitte skridt i retning af yderligere domesticering hver gang, den får unger eller sætter frø.

På denne måde sker der hele tiden en udvikling af tamhunden som art, og for hver generation bevæger den sig stille og roligt væk fra at være ulv. Denne proces er foregået i omkring siden jægerstenalderen for 40.000 år, længere end noget andet dyr. Derfor er hunden med tiden blevet menneskets bedste ven.

Does organic farming face distinctive livestock welfare issues? - A conceptual analysis
Provedor de dados: 21
Autores: Alrøe, Hugo Fjelsted; Vaarst, Mette; Kristensen, Erik Steen.
The recent development and growth of organic livestock farming and the related development of national and international regulations has fuelled discussions among scientists and philosophers concerning the proper conceptualisation of animal welfare. These discussions on livestock welfare in organic farming draw on the conventional discussions and disputes on animal welfare, which involve issues such as different definitions of welfare (clinical health, absence of suffering, sum of positive and negative experiences, etc.), the possibility for objective measures of animal welfare and the acceptable level of welfare. It seems clear that livestock welfare is a value-laden concept and that animal welfare science cannot be made independent of questions of values...

Yield and Economic Performance of Organic and Conventional Cotton-Based Farming Systems – Results from a Field Trial in India
Provedor de dados: 21
Autores: Forster, Dionys; Andres, Christian; Verma, Rajeev; Zundel, Christine; Messmer, Monika M.; Mäder, Paul.
The debate on the relative benefits of conventional and organic farming systems has in recent time gained significant interest. So far, global agricultural development has focused on increased productivity rather than on a holistic natural resource management for food security. Thus, developing more sustainable farming practices on a large scale is of utmost importance. However, information concerning the performance of farming systems under organic and conventional management in tropical and subtropical regions is scarce. This study presents agronomic and economic data from the conversion phase (2007–2010) of a farming systems comparison trial on a Vertisol soil in Madhya Pradesh, central India.

Effect of autumn application of urea on saprotrophic fungi in off-season leaf litter of sour cherry and evaluation of fungal isolates to reduce primary inoculum of Blumeriella jaapii
Provedor de dados: 21
Autores: Bengtsson, M.; Green, H.; Leroul, N.; Pedersen, H.L.; Hockenhull, J.
The effect of autumn application of urea on the activity and composition of saprotrophic fungi associated with sour cherry (Prunus cerasus) leaf litter infected with the leaf spot pathogen, Blumeriella jaapii, was studied under orchard conditions from the time of leaf fall to the release of ascospores, the following spring. The ability of treatment of infected leaves post leaf fall with urea or with inoculum of selected fungal strains to reduce primary inoculum (ascospores and winter conidia) of B. jaapii in spring was evaluated. Fungal activity was measured enzymatically by quantifying -N-acetylglycosaminidase and fungal composition and frequency were evaluated following isolation at low temperature of mycelia embedded in leaf particles.

A physiologically-based model of Cirsium arvense and Tussilago farfara growth and control
Provedor de dados: 21
Autores: Holst, Niels; Riemens, Marleen; Rasmussen, Ilse A.
Perennial herbs can be difficult to manage because of their underground storage organs which live sheltered from observation and control. In this paper, we describe the development of a population dynamics model for two perennial weeds, Cirsium arvense and Tussilago farfara. The model is physiologically based and includes plant growth and development,  and mowing as a control option. Model performance was compared with field data from monospecific stands of C. arvense in Denmark and Netherlands and of T. farfara in Denmark. Finally, optimal mowing strategies were explored with the model.

Autores: PHILLIPS, S L; SHAW, M W; WOLFE, M S.
Potatoes of a number of varieties of contrasting levels of resistance were planted in pure or mixed stands in four experiments over 3 years. Three experiments compared the late blight severity and progress in mixtures with that in pure stands. Disease on susceptible or moderately resistant varieties typical of those in commercial use was similar in mixtures and pure stands. In 2 of 3 years, there were slight reductions on cv. Sante, which is moderately susceptible, in mixture with cv. Cara, which is moderately resistant. Cara was unaffected by this mixture. Mixtures of an immune or near-immune partner with Cara or Sante substantially reduced disease on the latter.

Provedor de dados: 21
Autores: Trivedi, Mahendra Kumar; Branton, Alice; Trivedi, Dahryn; Nayak, Gopal.
Food production needs to increase to satisfy the demand due to increasing human population worldwide. To minimize this food crisis, an increase in the rice production is necessary in many countries. The current study was undertaken to evaluate the impact of Mr. Trivedi’s biofield energy treatment on rice (Oryza sativa) for its growth-germination of seedling, glutathione (GSH) content in seedling and mature plants, indole acetic acid (IAA) content in shoots and roots and DNA polymorphism by random amplified polymorphic-DNA (RAPD). The sample of O. sativa cv, 644 was divided into two groups. One group was remained as untreated and coded as control, while the other group was subjected to Mr. Trivedi for biofield energy treatment and denoted as treated sample....

Evolutionary plant breeding in cereals– into a new era
Provedor de dados: 21
Autores: Döring, Thomas; Knapp, Samuel; Kovacs, Geza; Wolfe, Martin.
In evolutionary plant breeding, crop populations with a high level of genetic diversity are subjected to the forces of natural selection. In a cycle of sowing and re-sowing seed from the plant population year after year, those plants favored under prevailing growing conditions are expected to contribute more seed to the next generation than plants with lower fitness. Thus, evolving crop populations have the capability of adapting to the conditions under which they are grown. Here we review the current state of research in evolutionary plant breeding and concentrate on the ability of evolving plant populations to deal with stressful, variable, and unpredictable environments. This resilience of evolving plant populations is seen as a major advantage under...

Conversion to Organic Farming: A typical example of the diffusion of an innovation?
Provedor de dados: 21
Autores: Padel, Susanne.
The paper reviews a wide range of studies of organic farmers published over the last 20 years using the framework of adoption/diffusion. The model that was developed by rural sociologists in the US and was the main guiding theory for the development of agricultural extension work. After a summary of the adoption/diffusion model and a short description of organic farming and its development in Europe, many similarities in personal and social characteristics of organic farmers in earlier and later studies with innovators and early adopters, particularly of environmental innovations are identified. The comparison of the characteristics of organic farming with other innovations shows differences, some of which have been used to develop some recommendations how...

Sharpening Up Research on Organics: Why We Need to Integrate Sectoral Policy Research into Mainstream Policy Analysis
Provedor de dados: 21
Autores: Daugbjerg, Carsten; Halpin, Darren.
As a fast growing state sponsored industry, the organic food sector is likely to attract the increased attention of policy analysts who are interested in industry development. We critically review the European comparative research on growth in the organic sector, focusing on policy analysis. A common element in these accounts is that findings are by no means clear on why variation in organic growth between countries exists. The literature provides a range of possible variables explaining divergent patterns of organic sector development but solid conclusions are elusive. We suggest that future policy orientated research on organic sector apply existing theories on public policy and carefully design studies in accordance with the prescriptions of the...

Cultivar improvement and environmental variability in yield removed nitrogen of spring cereals and rapeseed in northern growing conditions according to a long-term dataset
Provedor de dados: 21
Autores: Peltonen-Sainio, Pirjo; Jauhiainen, Lauri.
The balance between applied and harvested nitrogen (yield removed nitrogen, YRN %) is a recognized indicator of the risk of N leaching. In this study we monitored the genetic improvements and environmental variability as well as differences among crop species (spring cereals and rapeseed) in YRN in order to characterize changes that have occurred and environmental constraints associated with reducing N leaching into the environment. MTT long-term multi-location field experiments for spring cereals (Hordeum vulgare L., Avena sativa L. and Triticum aestivum L.), turnip rape (Brassica rapa L.), and oilseed rape (B. napus L.) were conducted in 1988–2008, covering each crop’s main production regions.

Autores: Jakobsen, M.; Hermansen, J.E.; Andersen, Heidi Mai-Lis; Jørgensen, Uffe; Labouriau, R.; Rasmussen, Jim; Kongsted, A.G.
Innovative strategies in free-range pig production is needed to improve the environmental performance of the system. Based on previous studies, inclusion of trees was hypothesized to improve the system’s nitrogen efficiency. We investigated sow elimination behaviour, faeces load and localisation as well as soil mineral nitrogen load in pasture based individual paddocks with and without access to two rows of poplar (Populus sp.) trees. Unlike expected sows showed no preference for eliminating in the zone with poplars but clearly avoided defecating near the hut, feed and water. Soil mineral nitrogen load showed a heterogeneous pattern as also found in previous studies. In comparison to grass, our results indicated that the poplars had an increased winter...

Autores: Høgh-Jensen, H; Myaka, F.A.; Sakala, W.D.; Kamalongo, D.; Ngwira, A.; Vesterager, J.M.; Odgaard, R.; Adu-Gyamfi, J.J.
Pigeonpea is one of the few crops with a high potential for resource-poor farmers due to its complementary resource use when intercropped with maize. A three year comprehensive comparative study on the performance of six pigeonpea (Cajanus cajan) varieties on farmers’ fields in Eastern and Southern Africa where intercropping with maize is normal practice, was undertaken. The varieties were tested for accumulation of dry matter (DM), nitrogen (N) and phosphorus (P) in all above-ground organs for three years under farmers’ conditions. The study revealed that the latest introduced ICEAP 00040 outperformed all the other tested varieties (ICP 9145; ICEAP 00020, ICEAP 00053, ICEAP 00068, and a local variety called “Babati White”) under farmer-managed conditions....

Implications of grazing by sows for nitrate leaching from grassland and the succeeding cereal crop
Provedor de dados: 21
Autores: Eriksen, J.
Outdoor pig production may have benefits in terms of animal welfare but could be undesirable in terms of nutrient losses. In paddocks on sandy soil grazed by lactating sows, nitrate leaching was determined using the suction cup technique from the start of grazing in October to after the following barley/pea wholecrop with perennial ryegrass. The inorganic N concentration in soil was uneven after sow grazing with the highest values found near the feeding area. In contrast to low nitrate leaching in the year of grazing (25-30 kg N ha-1), losses were considerable in the following autumn and winter. Throughout the measuring period of 18 months, nitrate leaching inside paddocks was on average 320 kg N ha-1 with the major part near the feeding area. Ten m from...

Manipulating within-orchard and adjacent habitats to provide better pest control in organic orchards. Some elements for modulating “orchard tree-pest-natural enemy” relationships
Provedor de dados: 21
Autores: SIMON, S.; SAUPHANOR, B.; DEFRANCE, H.; LAURI, P.E.
The control of pests in organic orchards cannot solely rely on the use of direct control methods. The effect of manipulating the habitat of orchard pests and natural enemies through tree architecture and the increase of plant diversity has been investigated in an experimental organic apple orchard and in a pear orchard, in order to provide information about the potential benefits of these cultural practices. Tree training affected the development of the most detrimental pests of apple trees, and the centrifugal training system globally provided better aphid (Dysaphis plantaginea) and mite (Panonychus ulmi) control than the more classical Solaxe system, whereas codling moth (Cydia pomonella) was favoured compared to Solaxe.

The Brazilian technical and scientific literature on Agroecology is plentiful, is scattered and of difficult access and the hypothesis is that the knowledge of the area was produced but is composed by a knowledge to be organized. These features are barriers and constrains for farmers to use agricultural information as well as for providers of extension services to meet information needs of farmers. In this direction there is a consensus among researchers who study the information that the adequate alternative and adopted in the entire world are the open access digital repositories. Besides taking into account all essential actions to manage technical and scientific information, the open access digital repositories contribute to better communication process...

Winter wheat roots grow twice as deep as spring wheat roots, is this important for N uptake and N leaching losses?
Provedor de dados: 21
Autores: Thorup-Kristensen, Kristian; Cortasa, Montserrat Salmerón; Loges, Ralf.
Cropping systems comprising winter catch crops followed by spring wheat could reduce N leaching risks compared to traditional winter wheat systems in humid climates. We studied the soil mineral N (Ninorg) and root growth of winter- and spring wheat to 2.5 m depth during three years. Root depth of winter wheat (2.2 m) was twice that of spring wheat, and this was related to much lower amounts of Ninorg in the 1 to 2.5 m layer after winter wheat (81 kg Ninorg ha-1 less). When growing winter catch crops before spring wheat, N content in the 1 to 2.5 m layer after spring wheat was not different from that after winter wheat. The results suggest that by virtue of its deep rooting, winter wheat may not lead to high levels of leaching as it is often assumed in...

The soil quality concept and its importance in the study of Finnish arable soils
Provedor de dados: 21
Autores: Palojärvi, Ansa; Nuutinen, Visa.
Arable soil is a functional unit whose condition is vital to crop production, but also to ecosystems at large owing to the significant role of soil in global nutrient cycles and balances. The soil quality concept recognises the concern for the sustainability of current arable land use practices. It integrates soil chemical, physical and biological properties, and takes account of the interaction of soil with water and air. This paper reviews the soil quality concept and its applications and discusses the importance of the concept for the assessment of Finnish arable soils. Many aspects of the chemical quality of arable soil are already well known in Finland. In contrast, follow-up of the physical and biological soil components, which are increasingly seen...

A radical shift in our approach to crop production is needed to ensure food security and to address the problems of soil degradation, loss of biodiversity, polluted and restricted water supplies, coupled with a future of fossil fuel limitations and increasingly variable climatic conditions. An interdisciplinary network of European scientists put forward visions for future crop production embracing the complexity of our socio-ecological system by applying the principle of diversity at all levels from soil micro-organisms to plant varieties and cropping systems. This approach, integrated with careful deployment of our finite global resources and implementation of appropriate sustainable technology, appears to be the only way to ensure the scale of system...

The difference in transfer of all-rac-a-tocopherol stereo-isomers to milk from cows and the effect on its oxidative stability
Provedor de dados: 21
Autores: Slots, T.; Skibsted, L.H.; Nielsen, J.H.
Milk from cows fed high concentration of synthetic all-rac-a-tocopheryl acetate (2-3 g day-1) were shown not to have improved oxidative stability, when oxidation were initiated by light exposure or Cu(II) addition. For milk with high fraction of unsaturated lipids as obtained through feed with toasted soybeans, the high a-tocopherol content even acted prooxidative. Stereo-selective analysis of the milk showed that among the 8 stereo-isomers of all-rac-a-tocopherol, only the 2R-stereo-isomers were excreted into the milk and among these mainly the native RRR-stereo-isomer. Feeding studies of dairy cows should accordingly be reevaluated in two respect: (i) the use of high level supplementation of a-tocopherol, as it may induce lipid oxidation, (ii) the use of...

Autores: Klocke, P.; Ivemeyer, S.; Butler, G.; Maeschli, A.; Heil, F.
Introduction: Routine use of antibiotics to prevent mastitis in dairy cows is prohibited by organic farming regulations. Internal Teat Sealers have been proposed as an alternative. We compared two drying-off (DO) supporting measures (Internal Teat Sealer and Homeopathy) to an untreated control group to assess their protective effects against clinical mastitis and intra-mammary infections during dry period of dairy cows.  Methods: A field trial with 102 dairy cows from 13 Swiss organic dairy farms was conducted. Cows were randomly assigned to one of three groups within a herd. In the Internal Teat Sealer group (ITS; 36 cows) cows were treated with the commercial ORBESEAL (Pfizer) in all four quarters immediately after the last milking. In the Homeopathy...

The assessment of the impacts of growing genetically modified (GM) crops remains a major political and scientific challenge in Europe. Concerns have been raised by the evidence of adverse and unexpected environmental effects and differing opinions on the outcomes of environmental risk assessments (ERA).  The current regulatory system is hampered by insufficiently developed methods for GM crop safety testing and introduction studies. Improvement to the regulatory system needs to address the lack of well designed GM crop monitoring frameworks, professional and financial conflicts of interest within the ERA research and testing community, weaknesses in consideration of stakeholder interests and specific regional conditions, and the lack of comprehensive...

Non-compliance in organic farming: A cross-country comparison of Italy and Germany
Provedor de dados: 21
Autores: Gambelli, Danilo; Solfanelli, Francesco; Zanoli, Raffaele; Zorn, Alexander; Lippert, Christian; Dabbert, Stephan.
This paper describes the Italian and German organic certification systems, including the institutions involved and the definitions of non-compliance and sanctions. Although they are both implementations of the same EU regulatory framework, these systems differ in many respects. Case study data from control bodies on non-compliance and sanctions are presented and analysed using binary choice models. This analysis shows that the occurrence of slight non-compliance and greater farm acreage are significant risk factors that explain severe non-compliance in both countries. However, to implement an efficient risk-based inspection system in the future, the data collection process must be improved and extended to examine personal attributes of  farmers and...

Cadmium uptake by cocoa trees in agroforestry and monoculture  systems under conventional and organic management
Provedor de dados: 21
Autores: Gramlich, A.; Tandy, S.; Andres, C.; Chincheros Paniagua, J.; Armengot, L.; Schneider, M.; Schulin, R.
Cadmium(Cd) uptake by cocoa has recently attracted attention, after the European Union (EU) decided to establish values for tolerable Cd concentrations in cocoa products. Bean Cd concentrations from some cocoa provenances, especially from Latin America, were found to exceed these values. Cadmium uptake by cocoa is expected not only to depend on a variety of soil factors, but also on plant and management factors. In this study, we investigated the influence of different production systems on Cd uptake by cocoa in a long-term field trial in the Alto Beni Region of Bolivia,where cocoa trees are grown inmonocultures and in agroforestry systems, both under organic and conventional management. Leaf, fruits and roots of two cultivars were sampled fromeach...

Tolerance to weed harrowing in four spring barley varieties
Provedor de dados: 21
Autores: Hansen, Preben Klarskov; Rasmussen, Ilse A.; Holst, Niels; Andreasen, Christian.
The aim of this study was to investigate possible interactions between a preventive and a curativ method  (combination of one pre and one post-emergence weed harrowing). We estimated the damages by weed harrowing in four pure varieties of spring barley, and analysed if there were differences in resistance and tolerance to weed harrowing between the varieties. As organic growing conditions are characterised by greater differences in nutrient levels, we further examined if there was any interactions between harrowing resistance and tolerance of the varieties and two nutrient level. Tolerance to weed harrowing was measured as an immediate effect (Resistance=how much of the plant is covered with soil after weed harrowing), a short-term effect (growth rate...

The aim of this study was to evaluate the interaction between yield levels of nonleguminous crops and soil organic matter (SOM) under the specific conditions of organic and conventional farming, respectively, and to identify implications for SOM management in arable farming considering the farming system (organic vs. conventional). For that purpose, correlations between yield levels of nonlegume crops and actual SOM level (Corg, Nt, Chwe, Nhwe) as well as SOM-level development were examined including primary data from selected treatments of seven long-term field experiments in Germany and Switzerland. Yield levels of nonlegume crops were positively correlated with SOM levels, but the correlation was significant only under conditions of organic farming, and...

Autores: Fleury, Lorena Cândido; Almeida, Jalcione.
O presente artigo tem como objetivo analisar os fundamentos teóricos para definição de um grupo social como "tradicional" e as implicações deste termo, freqüentemente norteado r para tomadas de decisão referentes ao manejo de unidades de conservação - como a decisão sobre a permanência ou não de comunidades em áreas de acentuado interesse ecológico -, para a conservação ambiental e a agroecologia. A partir da pesquisa bibliográfica constatou-se que as populações tradicionais, com forte correlação com a noção de "camponês", têm sido definidas pela sua inserção no meio envolvente, pelo uso de técnicas de baixo impacto ambiental e pelo respeito aos ciclos naturais. É destacado que, para uma comunidade ser considerada tradicional, esta não precisa ter padrões...

Organic viticulture and soil quality: A long-term study in Southern France
Provedor de dados: 21
Autores: Coll, Patrice; Le Cadre, Edith; Blanchart, Eric; Hinsinger, Philippe; Villenave, Cécile.
The rate of conversion of conventional vineyards into organic farming is currently increasing. This results in modifications of agricultural practices such as the application of organic manure, the use of tillage or grass-cutting to control weeds and the application of natural pesticides with preventive action. One of the aims of organic farming is to preserve the environment. In this context, the objective of our work was to evaluate the long-term effects of organic viticulture on soil quality. The study was conducted in a commercial vineyard where plots which had been organically managed for 7 (Organic7), 11 (Organic11) and 17 years (Organic17) were compared to conventionally managed plots (Conventional). Soil physical and chemical parameters (bulk...

Organic dairy farming in Norway under the 100% organically produced feed requirement
Provedor de dados: 21
Autores: Flaten, Ola; Lien, Gudbrand.
The derogation to use a percentage of cheaper non-organic feeds in organic livestock diets for herbivores expired from January 2008. (In Norway, a maximum 15% of conventional feedstuffs per year was allowed until 24 August 2005, 5% in the interim.) This study aimed to assess changes in resource use and financial impacts for organic dairy herds of the 100% organic feeding rule (compared with 85% organic feeds) using a two-stage stochastic programming modelling framework. In this study, the objective function was to maximise expected net income. Two organic dairy farms in the lowlands of southern Norway, both having a milk quota of 100,000 litres but with varying farmland availability (37 hectares vs. 20 hectares), were examined. Furthermore, situations with...

Agriculture as surface water polluter in the Danube River Basin and Central and Eastern Europe
Provedor de dados: 21
Autores: Znaor, Darko; Vollenbroek, Johan; Csikos, Imre.
More than a half of the territory of Central and Eastern Europe (CEE) is used for agricultural activities and agriculture represents an important economic activity of the region. But at the same time, agriculture in CEE is also a serious source of environmental degradations/pollution among which loss of biodiversity, soil and water ones seem to be most obvious. Moreover, regarding the pollution of water resources, particularly the surface water in CEE, it has been shown by several studies that agriculture represents major, much more serious source of pollution than any other sector (e.g. industry, transport, population, etc.). Among these studies, the results from the recent Danube Environmental Integrated Study, done within the framework of the UNDP...

Spatial variation in the localization of Danish organic farms
Provedor de dados: 21
Autores: Frederiksen, Pia; Langer, Vibeke.
Conversion to organic farming shows a large variation at the county level in Denmark. This is attributed to proximity to urban markets and values, regional specialization of farm types and municipal promotion of organic farming. However, also at the local level there is a substantial variation in the localization of organic farms. This may be related to negative influences of social barriers and positive influences of fiery souls among producers and advisors.

Zusammenfassung:    Im Bemühen um eine Reduzierung von Emissionen aus der landwirtschaftlichen Nutztierhaltung konkurrieren unterschiedliche Strategien im Hinblick auf Effektivität, Umsetzbarkeit und Nachhaltigkeit. In der herkömmlichen Tierproduktion kommen vorrangig solche Strategien zum Einsatz, bei denen der Austrag betrieblicher und importierter Nährstoffe in nachgelagerten Bereichen der Prozesskette mit Hilfe verschiedener Verfahrenstechniken reduziert wird. Demgegenüber basiert der systemorientierte Ansatz in der Ökologischen Tierhaltung auf dem Vermeidungsprinzip. Dabei wird auf risikobehaftete Produktionsmittel verzichtet und über eine gezielte Verknappung von Ressourcen der Nährstoffinput in den landwirtschaftlichen Betrieb drastisch gesenkt....

Autores: Melander, B.; Kristensen, J.K.; Kristensen, K.; Mathiassen, S.K.; Nørremark, M.; Kristensen , E.F.
Traditional strategies for controlling Elytrigia repens  infestations in organic cropping in Scandinavia are based on repeated post-harvest cultivation. However, post-harvest tillage is undesirable due to the need for retaining nutrients in the cropping systems. There is a need to look   for solutions where E. repens can be controlled over a short duration to allow replanting of the soil.   A Danish project is investigating new technologies that can meet such requirements. One aspect is to look for methods that physically can destruct the sprouting ability of E. repens rhizome buds. We investigated the effect of heating using hot water and mechanical crushing by pressure on the   sprouting ability of exposed rhizome buds. The effect of temperatures &lt;...

A sequential approach for improving AZODYN crop model under conventional and low-input conditions
Provedor de dados: 21
Autores: David, Christophe; Jeuffroy, Marie-Hélène.
Advances in scientific understanding of the plant and soil behaviour in a cultivated field led to the design of numerous soil-crop models simulating crop growth. The frequent low predictive quality of these models is linked to uncertainties in inputs, parameters and equations. The AZODYN crop model predicting wheat grain yield and grain protein content was previously developed to support decision for N management of conventional and organic wheat crops. This paper outlines a sequential approach to improve the predictions of the AZODYN model by testing various formalisms. This study is based on the comparison of 38 versions of the model assessed in multi-environment trials carried out under conventional or low-input conditions. This paper describes and...

Macroscopic leaf symptoms in wheat infected by Tilletia tritici
Provedor de dados: 21
Autores: Borgen, Anders; Kristensen, Lars.
Common bunt (Tilletia tritici) infects the wheat plant during germination of the seed. For experiments with common bunt it is conventional to examine symptoms of infection in the head of the plant. Previous research has advocated the possibility of scoring chlorosis on the leaf instead of head symptoms in order to reduce the duration of the experiment. By comparing the two diagnosis methods in climate chambers, the current experiment demonstrated that the sensitivity and specificity of the two methods depends on the wheat variety used. Using leaf symptoms as a diagnosis for infection has considerable disadvantages when used for screening for resistance in breeding programs, but have advantages e.g. when investigating effects of seed treatments.

Emmer wheat is suitable for organic and low-input farming systems, as it contributes to the enhancement of agrobiodiversity and an extension of the range of crop species with a higher added value. Although it has been grown for a very long time, it is now rarely utilised. The results of research into and examination of six cultivars coming from the genetic resources of the gene bank in Prague are presented. Particular morphological, biological, economic and quality characteristics were examined in respect of a cultivar’s ideotype for the organic farming system. A number of criteria for selection were proposed on the basis of an examination of particular characteristics and relationships. They respect the principles of breeding of cultivars for the organic...

Autores: Barataud, Fabienne; Aubry, C.; Wezel, A.; Mundler, P.; Fleury, Philippe.
Protecting water resources from pollutants generated by agricultural activities is becoming more strictly regulated in Europe today, with an obligation to achieveresults. This means that towns willing to improve quality of their domestic water supply are required to regulate farmers’ practices in the water catchment areas. In this paper, we studied three cases (Munich and Augsburg in Germany, and Lons-le-Saunier in France) often listed as successful initiatives/ experiences of preservation of water quality by local authorities that have developed coordination with farmers. In this paper, we carried out a comparative analysis of the construction of city-farmer agreements, based on in-depth surveys and with a particular focus on the role of conversion to...

Integrated control of gastrointestinal nematodes in lambs  using a bioactive feed x breed approach
Provedor de dados: 21
Autores: Werne, S.; Isensee, A.; Maurer, V.; Perler, E.; Drewek, A.; Heckendorn, F.
Forages rich in condensed tannins have repeatedly shown potential to reduce gastrointestinal nematode infection in sheep. Similarly, several breeds of sheep have shown a relative resistance to gastrointestinal nematodes (GIN). We hypothesised that additive or even synergic effects may arise from the combination of a relatively resistant breed and a diet rich in condensed tannins. In study I, 160 lambs of the native Red Engadine Sheep (RES) and 113 lambs of the Swiss White Alpine sheep (SWA) were artificially infected with GIN and subsequently grazed for 52 days. The lambs were then distributed to 2 groups for a 14-day experimental feeding period. One group received a diet with a proportion of 55% sainfoin and was compared to a control group on the basis of...

The organics iceberg and the tyranny of organic certification
Provedor de dados: 21
Autores: Paull, John.
The existence of an ‘organics iceberg’ is a hypothesis rather than a fact. Nevertheless, reports in The World of Organic Agriculture that there are 37,245,686 certified organic hectares worldwide and that this accounts for 0.86% of global agriculture are lower bounds, in fact underestimates, of the size and the achievements of the organics movement. While such statistics are seductively precise, they are merely the countable manifestation of a larger phenomenon, and perhaps a much larger phenomenon, which may be - an organics iceberg. Just how large is the uncounted ‘world of organic agriculture’, as compared to the counted world of certified organic agriculture, is a matter of speculation, but its existence is doubtless. In a recent study in India...

Autores: Ferreira, Luiz Carlos Britto; Machado Filho, Luiz Carlos Pinheiro; Hotzel, Maria José; Labarrère, Juliana Guimarães.
O objetivo foi avaliar o efeito de diferentes disponibilidades de sombreamento na distribuição das fezes na pastagem. Mediu-se as freqüências de distribuição das vacas e das fezes nas subáreas dos piquetes, num desenho experimental quadrado-latino (4x4), com os tratamentos: sem sombra (“sol”), sombra “única”, sombra em “bosque” e sombra “dispersa”. A análise estatística feita pelo teste do qui-quadrado constatou que as freqüências observadas das vacas e das fezes nos quadrantes foram diferentes das esperadas em todos os tratamentos (p&lt; 0,01), exceto para a distribuição das fezes no tratamento “dispersa”. A correlação entre a freqüência das vacas e a quantidade de fezes no mesmo quadrante foi de 79%, 49%, 62% e 3%, para os tratamentos sol, única, bosque...

Distinct Nitrogen Provisioning From Organic Amendments in Soil as Influenced by Farming System and Water Regime
Provedor de dados: 21
Autores: Lori, Martina; Symanczik, Sarah; Mäder, Paul; Efosa, Norah; Jaenicke, Sebastian; Buegger, Franz; Tresch, Simon; Goesmann, Alexander; Gattinger, Andreas.
The majority of soil organic nitrogen (N) is bound in protein-like compounds and therefore its proteolysis in peptides and amino acids is considered the initial and rate limiting step of N mineralization. Proteolysis of N bound in organic fertilizer and subsequent provisioning for crops is a central element in agro-ecological intensification. Long-term farming system effects on N provisioning from organic fertilizer to crops and its underlying functional microbial communities were analyzed in experiments conducted in soils from the “DOK” system comparison trial (bio-Dynamic, bio-Organic, and “Konventionell”) subjected to optimal and future projected drought scenarios. A plant nutrition experiment using 15N labeled lupine as a fertilizer (green manure)...

Use of water from small alluvial aquifers for irrigation in semi-arid regions.
Provedor de dados: 21
Autores: Burte, Julien Daniel Pierre; Coudrain, Anne; Marlet, Serge.
Water from small alluvial aquifers constitutes an attractive and low-cost option for irrigation and rural development in Northeastern Brazil. Based on piezometric measurements, geochemical analyses and electrical conductivity estimates, the present case study identified the main processes determining the hydrosaline dynamics of an alluvial aquifer in a small watershed inserted in the crystalline bedrock of a semi-arid region in Ceará and evaluated the availability of water for irrigation. Accumulation of salts in soil are related to evaporative flux from the aquifer and is increased by irrigation from the groundwater of the alluvial aquifer. The water in these aquifers may be used for irrigation, but represents a risk of soil salinization and...

Approaches to assess the environmental impact of organic farming with particular regard to Denmark
Provedor de dados: 21
Autores: Hansen, Birgitte; Alrøe, Hugo Fjelsted; Kristensen, Erik Steen.
Ever increasing attention is being paid to the environmental impact of intensive agricultural practices, and in this context organic farming is gaining recognition as a relatively friendly production system. In general, the risk of harmful environmental effects is lower with organic than with conventional farming methods, though not necessarily so. This review examines organic farming in the light of European conditions, with special regard to recent research findings from Denmark. It specifies the environmental problems caused by modern farming practices and discusses appropriate indicators for assessing their impact.    A Driving Force-State-Response (DSR) framework is employed to organise and understand the processes and mechanisms that lie behind the...

Kemink subsoiling before and after planting
Provedor de dados: 21
Autores: Bugge Henriksen, Christian; Rasmussen, Jesper; Søgaard, Carsten.
The Kemink Exact Soil Management System is a non-inversion soil management system based on subsoiling, ridges and controlled traffic. Previous studies have documented benefits of the Kemink system used in its entirety, but the isolated effect of Kemink subsoiling has not been investigated before. To determine the isolated effect of Kemink subsoiling before and after planting two field experiments in sugar beet and barley were conducted in 1999 and 2000 under low nutrient input conditions in a conventional soil management system without recognized compaction problems. Kemink subsoiling after planting generally showed a negative effect on the growth and yield of both crops, whereas subsoiling before planting increased sugar beet yield from 8.4 to 9.5 t ha-1...

The fate of nitrogen in outdoor pig production
Provedor de dados: 21
Autores: Eriksen, J; Petersen, SO; Sommer, SG.
There may be a conflict between animal welfare and nitrogen pollution in outdoor pig production. In response to concern about nitrogen being lost to the atmosphere and ground water we quantified spatial variation and temporal dynamics of mineral N, ammonia volatilization, denitrification and nitrate leaching from outdoor pig production at three commercial farms in Denmark. From paddocks containing farrowing sows substantial nitrogen losses were observed, particularly around the feeding areas. Gross ammonia emission rates varied between 0.08 and 1.26 kg N ha–1 d-1 and increased with animal density and N intake. The mean annual loss of ammonia per sow was 4.8 kg N. Denitrification rates averaged 0.52 kg N ha–1 d-1 in autumn following summer grazing with...

Tolerance and selectivity of cereal species and cultivars to postemergence weed harrowing
Provedor de dados: 21
Autores: Rasmussen, Jesper; Nielsen, Helle H.; Gundersen, Hanne.
Post-emergence weed harrowing and other cultivation methods to control weeds in early crop growth stages may result in crop damage due to low selectivity between crop and weeds. Crop tolerance to cultivation plays an important role but it has not been clearly defined and analysed. We introduce a procedure for analysing crop tolerance based on digital image analysis. Crop tolerance is defined as the ability of the crop to avoid yield loss from cultivation in the absence of weeds, and it has two components: resistance and recovery. Resistance is the ability of the crop to resist soil covering and recovery is the ability of recover from it. Soil covering is the percentage of the crop that has been buried due to cultivation. We analysed data from six field...

Entomological and functional role of floral strips in an organic apple orchard: Hymenopteran parasitoids as a case study
Provedor de dados: 21
Autores: Dib, Hazem; Libourel, Gilles; Warlop, François.
Habitat manipulation techniques improve the availability of resources required by natural enemies to increase their effectiveness. This study focused on the effects of floral strips on Hymenopteran parasitoid presence. The experiments were conducted during spring 2007 in one organic low-input apple orchard located in south-eastern France. The density and the diversity of parasitic wasps collected from sown floral strips were higher than those from mown plants. The family of parasitic wasps of Braconidae was strongly dominant, followed by Mymaridae and Pteromalidae. By studying 26 flowering species, the greatest diversity and density of parasitic wasps were collected from Potentilla reptans, Achillea millefolium, Trifolium repens and Torilis arvensis. In...

Autores: Huusela-Veistola, Erja; Jalli, Heikki; Salonen, Jukka; Pahkala, Katri; Laine, Antti.
Selection of an appropriate sowing time for some winter rye (Secale cereale) cultivars could reduce the need for crop protection measures. In this study the occurrence and status of pests and weeds in relation to sowing time and growth habit of winter rye was studied in southern Finland. This was done using three sowing times and four rye varieties in field trials conducted at three locations in 1999–2001. The early sown rye was severely affected by pests (Oscinella frit, Mayetiola destructor) and weeds, whereas postponing sowing for two weeks after the recommended sowing time in late August resulted in considerably less damage and the optimal establishment of crop stands. The German hybrid varieties Picasso and Esprit produced more tillers m-2 in autumn...

Milk yield, udder health and reproductive performance in Swedish organic and conventional dairy herds
Provedor de dados: 21
Autores: Fall, Nils; Emanuelson, Ulf.
Organic dairy farming is an expanding segment of the dairy sector where cow management differs from the conventional model in many respects. Thus, a comparative evaluation of disease and welfare status in organically and conventionally managed dairy cows is required. Assessment of milk yield, udder health and reproductive performance (RP) was done in 20 organically and 20 conventionally managed Swedish dairy herds. In accordance with earlier findings we confirmed lower milk yield in organic cows. Udder health and RP were chosen as indicators of animal health in view of their clinical relevance and the availability of appropriate data bases providing good background knowledge for further animal health assessment. No obvious differences were found in the...

Selectivity of weed harrowing in lupin
Provedor de dados: 21
Autores: Jensen, Rikke K.; Rasmussen, Jesper; Melander, Bo.
Three field experiments were conducted in lupin in 1997, 1998 and 1999 to study two aspects of selectivity of post-emergence weed harrowing; the ability of the crop to resist soil covering (the initial damage effect), and the ability of the crop to tolerate soil covering (the recovery effect). Each year soil covering curves and crop tolerance curves were established in three early growth stages of lupin. Soil covering curves connected weed control and crop soil cover in weedy plots, and crop tolerance curves connected crop yield and crop soil cover in weed-free plots. The experiments showed that both resistance and tolerance were unaffected by the growth stage of lupin within the range from the cotyledon to the 7 to 8 leaf growth stages. Tolerance to soil...

Optimal decisions in organic steer production - a model including winter feed level, grazing strategy and slaughtering policy
Provedor de dados: 21
Autores: Nielsen, B.K.; Kristensen, A.R.; Thamsborg, S.M.
Organic steer production demand several decisions concerning grazing strategy, feeding level in the winter and factors as slaughter weight and length of the fattening period. The production system can be difficult to optimise, therefore the objective of this study was to develop a model to optimise the grazing strategy, feed level in winter and time of fattening and slaughter in organic steer production with regard to economic output at steer level. The steer model is a 4-level hierarchical Markov process with decisions defined at three levels. Decisions taken in the model include grazing strategy (permanent or ryegrass/clover pasture), feed level in winter (high and low), time for beginning of fattening (age 19-27 months) and time of slaughter (age 19-30...

Nitrate leaching from organic arable crop rotations: effects of location, manure and catch crop
Provedor de dados: 21
Autores: Askegaard, Margrethe; Olesen, Jørgen E.; Kristensen, Kristian.
Nitrate leaching from crop rotations supporting organic grain production was investigated from 1997 to 2000 in a field experiment at three locations in Denmark on different soil types. Three experimental factors were included in the experiment in a factorial design: (1) proportion of N2-fixing crops in the rotation (crop rotation), (2) catch crop (with and without), and (3) manure (with and without). Three, four-course rotations were compared, two at each location. The nitrate leaching was measured using ceramic suction cells. Leaching losses from the crop rotation with grass–clover green manure and without catch crops were 104, 54 and 35 kgNha21 yr21 on the coarse sand, the loamy sand, and the sandy loam, respectively. There was no effect of manure...

Meat bone meal as fertiliser for barley and oat
Provedor de dados: 21
Autores: Chen, Lin; Kivelä, Jukka; Helenius, Juha; Kangas, Arjo.
The traditional production of mineral N and P fertilisers is unsustainable due its reliance on fossil fuels in the case of N, and on limited mineral resource stocks in the case of P. The use of alternative or complementary fertilisers that originate from organic waste materials is gaining interest. Organic farms, especially arable organic farms without livestock, need usable sources of plant nutrients. Meat bone meal (MBM), a potential organic fertiliser for agricultural crops, contains considerable amounts of nutrients (on average 8% N, 5% P, 1% K and 10% Ca). In EU countries, Commission regulation (EC) No 181/2006 authorised the use of MBM as an organic fertiliser. In this study, MBM was compared to conventional mineral NPK fertiliser. Two randomised...

Identification of Heterotrophic Zinc Mobilization Processes  among Bacterial Strains Isolated from Wheat Rhizosphere  (Triticum aestivum L.)
Provedor de dados: 21
Autores: Costerousse, Benjamin; Schönholzer-Mauclaire, Laurie; Frossard, Emmanuel; Thonar, Cécile.
Soil and plant inoculation with heterotrophic zinc-solubilizing bacteria (ZSB) is considered a promising approach for increasing zinc (Zn) phytoavailability and enhancing crop growth and nutritional quality. Nevertheless, it is necessary to understand the underlying bacterial solubilization processes to predict their repeatability in inoculation strategies. Acidification via gluconic acid production remains the most reported process. In this study, wheat rhizosphere soil serial dilutions were plated on several solid microbiological media supplemented with scarcely soluble Zn oxide (ZnO), and 115 putative Zn-solubilizing isolates were directly detected based on the formation of solubilization halos around the colonies. Eight strains were selected based on...

Green accounts or Input-Output Accounting systems (IOA) have been developed in countries with intensive agricultural production to facilitate voluntary improvements in farm environmental performance. There is a need for an overview of indicators used and a review of results and experiences reported. Ten IOA systems covering the topics of the farm's use of nutrients, pesticides and energy were selected from a survey of 55 systems and compared in this paper. The approaches and indicators used vary from systems based on Good Agricultural Practices (GAP) to accounts based systems that use physical input-output units. Many IOA systems use farm gate nutrient balances, pesticide use per ha and energy use per kg product. These indicators are easy to calculate but...

Festulolium (X Festulolium) has shown a considerable yield potential as a fodder crop and as a direct effect the seed production area in Denmark has increased. The main aim for the present trial is a growing interest for festulolium in organic production systems and hence the requirements for organic produced seed. A 3-year study was conducted to determine the seed yield response in two different types of festulolium in respect to three seed rates (8, 12 and 16 kg ha-1) and three row spacings (12, 24 and 36 cm). The lolium type cv. Paulita was not affected by seeding rate or row spacing. In the tall fescue type cv. Hykor no significant difference in seed yields were found in respect to seeding rate but narrow row spacing 12 and 24 cm yielded more than 36...

Mechanical In-Row Weed Control in Transplanted and Direct-Sown Bulb Onions
Provedor de dados: 21
Autores: Ascard, Johan; Fogelberg, Fredrik.
Different strategies for mechanical in-row weed control were evaluated in direct-sown and transplanted bulb onions (Allium cepa) in terms of in-row weeds, labour requirements for hand weeding and marketable yield. Transplanted onions generally performed much better than direct sown onions. The best strategies in transplanted onions decreased the hand weeding time by 70% and increased marketable yield by 96% compared with the best strategies in direct-sown onions.      In transplanted onions, one weed harrowing and three in-row cultivations with torsion weeders reduced in-row weed numbers by 85%, reduced hand weeding time by 73%, and caused no yield reduction compared with the normal strategy of one weed harrowing and ordinary inter-row cultivation. In...

Assessing the recreational demand for agricultural land in Finland
Provedor de dados: 21
Autores: Pouta, Eija; Ovaskainen, Ville.
It is widely assumed that the scenic attractiveness and other public good aspects of agricultural land can be utilized as a source of livelihood in rural areas in the form of recreation and tourism. In this study we use two approaches to consider whether agricultural landscapes are preferred as a destination for recreation (day trips) and rural tourism (overnight trips). We first analyse the choice of recreation site type based on a model that aggregates sites using the presence of agricultural land as an aggregation variable. Population survey data on recreation trips reveal an association between the respondent’s living environment, recreational activities and visit characteristics and the probability of choosing a destination with agricultural land....

Animal production from dairy breed steers at extensively managed grasslands in riverside areas
Provedor de dados: 21
Autores: Nielsen, A.L.; Kristensen, T.; Badsberg, J.H.
In Denmark, some of the grassland in marginal areas are abandoned for agricultural use - grassland that it is of interest to preserve because they have a high actural or potential natural quality when managed with extensive grazing or cuttting. A comparison was carried out for three years on sward productivity and weight gain of the steers at two grazing intensities on wet semi-natural grassland. The daily weight gain of steers was on average 667 g at low and 477 g at high grazing intensity. Sward grass yield as dry matter (DM) production was on average 4.1 Mg DM ha4, with no significant difference sound between the two gazing intensities. In vitroorganic matter digestibility (IVOMD) was rexpectigely 56.4 and 53.0 at high and low grazing intensity. It is...

Structural vulnerability of a sandy loam exposed to intensive tillage and traffic in wet conditions
Provedor de dados: 21
Autores: Munkholm, L.J.; Schjønning, P.
Sustainable soil management requires that the structural degradation is balanced or exceeded by regeneration. Our objective was to investigate the vulnerability of topsoil structure to stress exerted by intensive tillage or traffic. The study addressed the short-term stability to disturbance as well as the recovery (resilience) within a year. A field experiment was conducted in a randomized block design on a humid sandy loam in 1997-1999. Each year, either compaction from a heavy tractor (PAC) or puddling by intensive rotary cultivation (PUD) produced a severe impact on topsoil structure. The PAC and PUD treatments were carried out on wet soil in early spring. The mechanical treatments were referenced by plots (REF), which were left undisturbed until the...

The Swiss agrienvironmental programme and its effects on selected biodiversity indicators
Provedor de dados: 21
Autores: Jeanneret, Philippe; Schüpbach, Beatrice; Pfiffner, Lukas; Herzog, Félix; Walter, Thomas.
In Switzerland, parallel to agri-environmental measures which apply directly to the field management, farmers had to convert at least 7% of their land to ecological compensation areas – ECA. Major ECA are extensified grassland, traditional orchards, hedges, and wild flower strips. In 2000, the situation shows that farmers practise the agri-environmental scheme all over Switzerland with a total of 120,000 hectares of different types of ECA. The introduction of ECA throughout the country's agricultural area can be seen as a large scale landscape restoration experiment. Its biological effects are evaluated in a monitoring programme. In a case study area of about 6 km2, in 1997, biodiversity indicators (spiders, carabid beetle and butterflies) were recorded...

The impact of organic agriculture on food quality
Provedor de dados: 21
Autores: Rembiałkowska, Ewa.
During last decades the consumer trust in food quality has drastically decreased, mainly because of the growing ecological awareness and several food scandals like Bovine Spongiform Encephalopathy (BSE), dioxins and bacterial contamination. It has been found that intensive conventional agriculture could introduce contaminants into food chain, first of all nitrates and nitrosamines, residues of pesticides, antibiotics and growth hormones. Consumers started to look for safer and better controlled foods, produced in more environmentally friendly, authentic and local system.       Organically produced foods are widely believed to satisfy the above demands, providing better environment and higher nutritive values. Several research studies conducted in many...

Autores: Home, Robert; Hunziker, Marcel; Bauer, Nicole.
High-density urban living means that urban green spaces are important nodes of contact with nature. This study examines expected outcomes that motivate people to seek green spaces in urban settings. A sample of Swiss residents were presented with Shin, Kwon, Hammitt, and Kim's (2005) psychosocial outcomes scale and asked which activities they choose to undertake in nearby natural areas. The most important motivations for visiting nearby green spaces were related to restoration, with social bonding as a desirable side benefit. There were few observable differences between urban and rural residents and level of education attained. Older people are motivated to visit nearby green spaces by the wish to seek social contact while younger people are motivated by...

The Lost History of Organic Farming in Australia
Provedor de dados: 21
Autores: Paull, John.
It has not been previously reported that the world’s first “organic” farming society was the Australian Organic Farming and Gardening Society (AOFGS) which was founded in Australia in October 1944. The association was based in Sydney, New South Wales, and the first issue of its journal, the Organic Farming Digest (OFD), was dated April 1946. This was Australia’s first, and the world’s second, “organic” farming journal. The eighteen month delay between the founding of the society and the first publication of the journal was because paper was unavailable in Australia for that purpose during WWII. The society published a total of 378 articles in 29 issues from 1946 to 1954. Articles from Australia, UK, USA, New Zealand, South Africa, Germany and Denmark were...

Soil strength and soil pore characteristics for direct-drilled and ploughed soils
Provedor de dados: 21
Autores: Schjønning, P.; Rasmussen, K.J.
Direct drilling has often been reported to increase density and strength and to affect pore continuity and tortuosity of the upper soil layers. In this study these aspects were studied for three texturally differing soils 4–6 years after initiation of continuous trials with direct drilling and mouldboard ploughing. The soils studied were a coarse sandy soil (Korntved, 5% clay), a sandy loam (Ballum, 8% clay) and a silty loam (Højer, 19% clay). The crop rotation at Korntved was spring barley and winter rye while at Ballum and Højer it was spring barley and winter wheat. Both crops were grown every year. All fields had been mouldboard ploughed for decades prior to the trial period. The ploughed treatment (PL) was imposed in the autumn and the seedbed...

Homeopathy Myth Or Medicine: A Clinical Study
Provedor de dados: 21
Autores: Sethi, Kumar; Chouhan,.
Excessive use of antibiotic to treat sick animals and as food supplement to boost production leads to emergence of  resistant microbes, which when transferred to human through food chain results in infection, needing larger doses and stronger drugs.Homeopathy can offer a great advantage in avoiding the need of chemicals/antibiotics in animal farming, particularly organic ones.Unfortunately double blind clinical trials of Homeopathic drugs on animal diseases published so far, concludes that scientific proof for efficacy of homeopathy is either lacking or not statistically valid.(Vockeroth 1999,K de verdier 2003,L. Hektoen 2004). The question is how far these trials are methodologically correct, from Homeopathic view and will be discussed.

Welfare, health and product quality in organic beef production - a Danish perspective
Provedor de dados: 21
Autores: Nielsen, B.; Thamsborg, S.M.
Organic beef production in Europe is based on grazing in the summertime and feeding of minimum 60% of roughage during the whole year. Although these recommendations were intended to improve health and welfare several aspects may cause problems in organic beef production systems. This paper gives an overview of welfare, health and product quality in organic beef production with emphasis on organic steer production based on dairy breed bull calves. A short overview of different production systems is given with emphasis on the effect on health, and welfare. Feeding aspects are discussed. Farm studies have shown that organic steer production is based on high amounts of roughages, and only small amounts of cereals are used compared to a conventional production...

Biological activity of Citrus spp. metabolites on Ceratitis capitata (Wiedemann).
Provedor de dados: 21
Autores: Faraone, Nicoletta; Caleca, Virgilio; Bruno, Maurizio; Vitagliano, Silvia; De Cristofaro, Antonio.
The Mediterranean fruit fly (medfly), Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), is one of the most injurious pest at global level. During the last years, several electrophysiological and behavioural studies have been carried out in order to investigate plant volatile compound-insect interactions with the aim to use this knowledge in sustainable control techniques.  It has been observed that lemons are not attacked by medfly, probably because of the peel oil, that is toxic to other fruit flies. In the present paper electrophysiological recordings were conducted to evaluate the insect sensitivity to peel extract and peel oil of two Sicilian cultivars (Interdonato and Lunario) of Citrus x limon (L.) Burm.f. on C. capitata females. Behavioural...

Ökologischer Sojaanbau in kälteren Gebieten Deutschlands?
Provedor de dados: 21
Autores: Paffrath, Andreas; Henneberger, Matthias; Mayer, Jochen.
Bisher können Sojabohnen in Deutschland nur in klimatisch begünstigten Gebieten wie z.B. im Raum Freiburg, der Oberrheinebene und in Südbayern einigermaßen erfolgreich angebaut werden. Aufgrund ihrer hohen Temperaturansprüche sind für Soja nur Lagen geeignet, in denen auch Körnermais angebaut werden kann. Die Aussaat erfolgt von Ende April bis Anfang Mai. Neuere Sorten könnten jedoch auch für den Sojaanbau in etwas kälteren Gebiete Deutschlands interessant sein.    Zur Klärung dieser Frage wurden im Jahr 2001 am Gartenbau-Zentrum Köln-Auweiler der Landwirtschaftskammer Rheinland(Jahresmitteltemperatur: 9,5 °C) sechs Soja-Sorten, und auf dem Versuchsgut der Universität Kassel-Witzenhausen, der Domäne Frankenhausen (nördlich von Kassel;...

Soil fertility building measures should be explored at the short and long-term for an adequate evaluation of their impact on sustaining yields and of its environmental consequences in crop rotations under organic farming. For such a purpose, process-based crop models are potential useful tools to complement and upscale field observations under a range of soil and climatic conditions. Organic rotations differ in soil fertility dynamics in comparison to conventional farming but very few modelling studies have explicitly considered this specific situation. Here, we evaluate the FASSET model to predict the effects of different fertility management options in organic crop rotations on dry matter (DM) and nitrogen (N) yield, and soil N dynamics, including N2O...

Evolutionary plant breeding for low input systems
Provedor de dados: 21
Autores: Phillips, Scott; Wolfe, Martin.
Heritable variation is at the heart of the process of evolution. However, variation is restricted in breeding for uniform crop populations using the pedigree line approach. Pedigree lines are successful in agriculture because synthetic inputs are used to raise fertility and control weeds, pests and diseases.  An alternative method promoted for exploring the value of variation and evolutionary fitness in crops is to create composite cross populations. Composite cross populations are formed by assembling seed stocks with diverse evolutionary origins, recombination of these stocks by hybridization, the bulking of F1 progeny, and subsequent natural  election for mass sorting of the progeny in successive natural cropping environments. Composite cross...

Mussel shells as an environment enrichment and calcium source for floor-housed laying hens
Provedor de dados: 21
Autores: Alm, M.; Tauson, R.; Wall, H.
Feather pecking is still a behavioral problem in laying hen flocks, resulting in impaired welfare and economic losses. Environment enrichment, e.g., providing access to litter, to increase foraging behavior in laying hens has been shown to decrease feather pecking. This study investigated the effect of spreading crushed mussel shells (particle size 10 to 20 mm) in the litter area as an environment enrichment and source of calcium for layers receiving a commercial feed and for layers given a feed with 40% less calcium. These treatments were compared with a control involving hens given the commercial feed, but no mussel shells in the litter. The study included 900 Dekalb White layers housed in a single-tier floor system during a production cycle (20 to 72 wk...

Farm enterprises as self-organizing systems: A new transdisciplinary framework for studying farm enterprises?
Provedor de dados: 21
Autores: Noe, Egon; Alrøe, Hugo Fjelsted.
The growing attention to sustainable food production and multifunctional agriculture calls for a multidisciplinary or transdisciplinary research and development perspective on farming, which is able to grasp the environmental, social, technical, and financial aspects of a farm and the dynamic relationship between the farm enterprises and the surrounding world. Our thesis is that a transdisciplinary approach needs to build on a working ontology that goes beyond the epistemology of each discipline and that is not just pieced together of the ontologies connected to these different epistemologies. Based on a review of three prevailing theoretical frameworks within the field of agro-sociology: The farming styles approach, the Bawden approach, and Conway’s...

Reproductive performance, general health, and longevity of dairy cows at a Swedish research farm with both organic and conventional production
Provedor de dados: 21
Autores: Fall, Nils; Forslund, Kristina; Emanuelson, Ulf.
Data from a 12-year longitudinal study was used to compare reproductive performance (RP), general animal health, and longevity in conventionally managed dairy cows and organically managed dairy cows. All cows were held at the same farm and managed by the same personnel. The management of the groups was basically alike, with the main exception being differences in feed composition and feeding regimes. Management of the organic group was done according to the Swedish standards for organic farming, which are certified by the International Federation of Agricultural Movements. The data for this study included all cows calving from September 1, 1990 to August 31, 2001; in total 154 organically and 156 conventionally managed animals. Calving-to-first...

Forage production strategies for improved profitability in organic dairy production at high latitudes
Provedor de dados: 21
Autores: Flaten, O.; Bakken, A.K.; Lindås, A.; Steinshamn, H.
The objective of this paper was to examine how cutting frequency, silage fermentation patterns and clover performance in grass–clover swards influence the use of inputs and profitability in an organic dairy system. A linear programming model was developed to compare a three-cut and a two-cut system for a model farm in Central Norway, either with restricted or extensive silage fermentation at low or high red clover (Trifolium pratense L.) proportion in the sward, giving 8 different silage types in all. Input-output relations incorporated into the model were derived from a meta-analysis of organic grassland field trials in Norway as well as a silage fermentation experiment, and with feed intakes and milk yields from simulations with the ‘TINE Optifôr’ feed...

Incredible Edible Todmorden: Eating the Street
Provedor de dados: 21
Autores: Paull, John.
The Yorkshire village of Todmorden has taken local food to heart – and to the street. The planting of food crops at forty public locations throughout the village offer locals, and visitors, the chance to pick their own fresh fruit and vegetables, and it’s all free. The idea of open source food took some time to catch on in Todmorden. Public space food plantings, “propaganda gardens”,  are a tangible expression of a set of bigger ideas – including growing local, eating local and fresh, eating seasonal, and knowing the provenance of food. Now, from the local police station to the cemetery, from the health centre to the elderly care home (with raised garden beds at wheelchair height), in tubs on the street and in plots dug by the canal, Todmorden is embracing...

The comparison of nitrogen use and leaching in sole cropped versus intercropped pea and barley
Provedor de dados: 21
Autores: Hauggaard-Nielsen, Henrik; Ambus, Per; Jensen, Erik Steen.
The effect of sole and intercropping of field pea (Pisum sativum L.) and spring barley (Hordeum vulgare L.) and of crop residue management on crop yield, NO3- leaching and N balance in the cropping system was tested in a 2-year lysimeter experiment on a temperate sandy loam soil. The crop rotation was pea and barley sole and intercrops followed by winter-rye and a fallow period. The Land Equivalent Ratio (LER), which is defined as the relative land area under sole crops that is required to produce the yields achieved in intercropping, were used to compare intercropping performance relative to sole cropping. Crops received no fertilizer in the experimental period. Natural 15N abundance techniques were used to determine pea N2 fixation.   The pea-barley...

Provedor de dados: 21
Autores: Weibel, Franco P.; Leder, Alfred.
The choice of suitable cultivars is of central importance to successful organic fruit production. Because of the limited options for plant protection, organic fruit production places particularly high demands on disease and pest tolerance or resistance. Additionally, management aspects must be considered such as marketing options, available sites, and the desired farm structure.

Profitability of twelve small-scale organic vegetable crops grown in a greenhouse in the North East of Scotland
Provedor de dados: 21
Autores: Dybek, Mr Konrad.
The paper examines the profitability of twelve polytunnel vegetable crops grown for an organic box scheme in Scotland. All inputs attributable to specific crops, labour in particular, were recorded during 2008 growing season and expressed in monetary values. Costs of the tunnel construction and maintenance have also been included. Based on sales data and inputs, annual net margins were calculated. Assuming the cost of labour as 7.25 £/hour only five of twelve vegetables were profitable. Results varied from 25.2 £/m2/year for cucumbers to -9.7 £/m2/year (loss) for batavian lettuce, average for all the crops was 3.38 £/m2/year. No significant difference in profitability could be ascertained between the following cultural methods: direct sown versus...

The need to breed crop varieties suitable for organic farming, using wheat, tomato and broccoli as examples: A review
Provedor de dados: 21
Autores: Lammerts van Bueren, E. T.; Jones, S.S.; Tamm, L.; Murphy, K.M.; Myers, J. R; Leifert, C.; Messmer, M.
It is estimated that more than 95% of organic production is based on crop varieties that were bred for the conventional high-input sector. Recent studies have shown that such varieties lack important traits required under organic and low-input production conditions. This is primarily due to selection in conventional breeding programmes being carried out in the background of high inorganic fertilizer and crop protection inputs. Also, some of the traits (e.g., semi-dwarf genes) that were introduced to address problems like lodging in cereals in high-input systems were shown to have negative side-effects (reduced resistance to diseases such as Septoria, lower protein content and poorer nutrient-use efficiency) on the performance of varieties under organic and...

Areas that comprise “damping zones” are important in minimizing the effects of impacts on the environment as they  can affect the conservation unit, and in helping to maintain its natural resources. However, they are not protected and many are handled improperly, compromising the sustainability of the conservation units they should protect. The aim of this study was to evaluate the effect of human disturbance in the damping zone on the soil quality inside the Biological Reserve Serra dos Toledos,Itajubá-MG. For this, there were selected three areas under different activities in the damping zone (pasture, agriculture, and native forest) and three areas sided to those, within the Reserve. They were characterized according to various physical,...

Pressurised liquid extraction of flavonoids in onions.  Method development and validation
Provedor de dados: 21
Autores: Søltoft, Malene; Christensen, J.H.; Nielsen, J.; Knuthsen, Pia.
A rapid and reliable analytical method for quantification of flavonoids in onions was developed and validated. Five extraction methods were tested on freeze-dried onions and subsequently high performance liquid chromatography (HPLC) with UV detection was used for quantification of seven flavonoids.    The extraction efficiencies were lowest for the conventional water bath extraction compared to pressurized liquid extraction (PLE), ultrasonication, ultrasonic liquid processor, and microwave extraction, which yielded similar efficiencies. The reproducibility was in the same range (RSD: 1–11%) for all tested extraction methods. However, PLE was the preferred extraction method because the method can be highly automated, use only small amounts of solvents,...

Survey on natural occurrence of Cydia Pomonella granulovirus in apple orchards of Iran
Provedor de dados: 21
Autores: Rezapanah, M.; Kharrazi-Pakdel, A.; Kamali, K.; Huber, J.
The Cydia pomonella granulovirlls (CpGV) is a very effective biological control agent against codling moth, Cydia pomonella L. (Lep.: Tortricidae). Its isolation from natural populations of codling moth is difficult and only a few isolates have been described in the world, because diseased larvae usually rupture and disintegrate and can not be found on the trees. So, in this survey, lots of corrugated cardboard trap bands were placed around the trunks of apple trees in different regions of Iran and they were surveyed for codling moth larvae infected by CpGV. At least, 11 natural isolates from Northwest and Northeast of Iran were collected and surveyed. Viruses from single or pooled infected larvae were isolated and propagated in the fourth in star larvae...

An Innovative Approach towards Organic Management of Late Blight in Potato under Inhana Rational Farming Technology
Provedor de dados: 21
Autores: Bera, R; Seal, A; Chowdhury, R. Roy; Datta, A; Saha, S; Sengupta, K.
Successful disease combat of crop can ensure healthy return for the farmers. However, limitation in the conventional disease management approach, especially in case of late blight of potato was the background for the present study that aimed at bringing forth an alternative pathway for effective disease management. Integrated farming under Inhana rational farming technology (IRF) was adopted as an alternate protocol. The approach works on the philosophy of the Trophobiosis theory that advocates pest/disease management through plant physiology management. The study was done in two major potato growing zones of West Bengal taking two major potato varieties i.e., Kufri Jyoti and Kufri Chandramukhi. Late blight incidence varied from 2.82 to 7.91% in the IRF...

Autores: Tyystjärvi, Esa; Nørremark, Michael; Mattila, Heta; Keränen, Mika; Hakala-Yatkin, Marja; Ottosen, Carl-Otto; Rosenqvist, Eva.
Automatic identification of crop and weed species is  required for many precision farming practices. The use of chlorophyll fluorescence fingerprinting for identification   of maize and barley among six weed species was tested. The plants were grown in outdoor pots and the fluorescence measurements were done in variable natural conditions.   The measurement protocol consisted of 1 s of shading followed by two short pulses of strong light photosynthetic photon flux density 1700 lmol m-2 s-1) with 0.2 s of darkness in between. Both illumination pulses caused the fluorescence yield to increase by 30–60% and to display a rapid fluorescence transient resembling transients obtained after long dark incubation.

Net blotch severity is best assessed at early grain filling with respect to its effect on grain weight of spring barley
Provedor de dados: 21
Autores: Pinnschmidt, Hans O.; Vollmer, Jeanette H.; Østergård, Hanne; Munk, Lisa.
Appropriate disease assessment methods and parameters reflecting whole-season disease severity levels in field plots remain important issues in studies related to plant disease epidemiology, disease resistance of crop cultivars, and disease-induced yield losses. Such methods and parameters should be yield-related to ensure relevance. Net blotch severity was determined over time in inoculated and non-inoculated field plots of three spring barley varieties by whole plot assessments and by assessments of individual leaves of single main tillers. Disease severity measures such as the area-under-disease-progress-curve, mean and maximum severity as well as severity levels at specific growth stages (GS) were derived from the data. Their relation to thousand grain...

Where is urban food policy in Switzerland? A frame analysis
Provedor de dados: 21
Autores: Moschitz, Heidrun.
Food is increasingly included on the urban agenda in many countries, and comprehensive food policies have been developed in several cities, but the development of articulate urban food policies is still in its infancy in Switzerland. The goal of this paper is to explore the ways in which food is framed in official policies in Switzerland and thereby gain a better understanding of the potential for the development of urban food policies. The analysis is based on a case study approach focusing on the formal frames of food: reconstructed from official policy documents on agriculture, food, health, environment, and planning, at the federal and the local level. The results show that urban food is not a major topic in most policy documents and that the dominant...

Competition and facilitation in synthetic communities of arbuscular mycorrhizal fungi
Provedor de dados: 21
Autores: Thonar, C.; Frossard, E.; Šmilauer, P.; Jansa, J.
Interactions between arbuscular mycorrhizal fungal (AMF) species cocolonizing the same host plant are still little understood in spite of major ecological significance of mycorrhizal symbiosis and widespread occurrence of these fungi in communities rather than alone. Furthermore, shifting the composition of AMF communities has demonstrated consequences for the provision of symbiotic benefits to the host as well as for the qualities of ecosystem services. Therefore, here we addressed the nature and strength of interactions between three different AMF species in all possible two-species combinations on a gradient of inoculation densities. Fungal communities were established in pots with Medicago truncatula plants, and their composition was assessed with...

Autores: Bodenhausen, Natacha; Somerville, Vincent; Desirò, Alessandro; Walser, Jean-Claude; Borghi, Lorenzo; van der Heijden, Marcel G. A.; Schlaeppi, Klaus.
Phosphorus (P) is a limiting element for plant growth. Several root microbes, including arbuscular mycorrhizal fungi (AMF), have the capacity to improve plant nutrition and their abundance is known to depend on P fertility. However, how complex root-associated bacterial and fungal communities respond to changes in P availability remains ill-defined. We manipulated the availability of soil P in pots and compared the root microbiota of non-mycorrhizal Arabidopsis with mycorrhizal Petunia plants. Root bacteria and fungi were profiled using ribosomal operon gene fragment sequencing, we searched for P sensitive microbes and tested whether a P sensitive core microbiome could be identified. Root microbiota composition varied substantially by P availability. A P...

1. Pollination interactions comprise a network of connections between flowers and insect visitors. They are crucial for reproductive success in many angiosperms but are threatened by intensive agricultural practices. Although less intensive approaches, including organic farming, could improve farmland biodiversity, it is not clear whether or not these approaches enhance wild plant pollination and the stability of insect–flower interaction networks.    2. We investigated the effects of organic vs. conventional farming on insect–flower interaction network size and structure, bee and hoverfly diversity, and pollination in 10 pairs of organic and conventional dairy farms in the Republic of Ireland.    3. We found that insect–flower interaction networks on...

Autores: Laursen, Kristian Holst; Hansen, Thomas Hesselhøj; Persson, Daniel Pergament; Schjørring, Jan Kofod; Husted, Søren.
The multi-elemental capacity of Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) is rarely fully utilized in traditional full-quantitative analysis. The main obstacles are limited availability of multi-elemental standards and the need for time-consuming external calibrations. In this study, a novel semi-quantitative quadrupole ICP-MS based method for multi-elemental fingerprinting of plant tissue was developed as a high-throughput alternative to full-quantitative analysis. The main analytical objectives were low data acquisition time (&lt;60 seconds), detailed coverage of the atomic mass range from 7Li to 238U and discrimination power similar to full-quantitative analysis based on chemometric data analysis. The method was tested on grains of different...

Il lepidottero nottuide Mamestra brassicae L. rappresenta un grave problema per le  coltivazioni di cavolo verza presenti in provincia di Torino; le uova, deposte sulla  pagina inferiore delle foglie, sono spesso difficili da individuare e le larve, che si generano da esse, vengono individuate dagli agricoltori quando hanno ormai raggiunto  dimensioni notevoli, tali da renderle meno sensibili agli insetticidi.  Gli Imenotteri Tricogrammatidi possono rappresentare un efficace fattore naturale di  contenimento di questi insetti, ma la loro attività è spesso ostacolata dai prodotti di  sintesi impiegati per la difesa della coltura. Anche i principi attivi naturali come piretro e zolfo bagnabile possono influenzare la loro presenza; alcune osservazioni...

Pseudomonas protegens CHA0 does not increase phosphorus uptake from 33P labeled synthetic hydroxyapatite by wheat grown on calcareous soil
Provedor de dados: 21
Autores: Meyer, G.; Maurhofer, M.; Frossard, E.; Gamper, H. A.; Mäder, P.; Mészáros, É.; Schönholzer-Mauclaire, L.; Symanczik, S.; Oberson, A.
Soil microorganisms exuding organic acids have the potential to solubilize inorganic phosphorus (P), which could improve the P availability to plants growing on calcareous soil. The gluconic acid exuding bacteria Pseudomonas protegens CHA0 can solubilize P under glucose rich in vitro conditions, but evidence on the effectiveness in soil is lacking. This discrepancy in P solubilization between in vitro and in vivo is common for many P solubilizing bacteria. Possible causes for this discrepancy are rarely explored in soil using mechanism oriented approaches. Proposed reasons for limitation of bacterial P solubilization in soil are low persistence of the inoculant or low glucose availability in the plant rhizosphere. To test these two hypotheses we...

Variation in the plant-mediated methane transport and its importance for methane emission from intact wetland peat mesocosms
Provedor de dados: 21
Autores: Bhullar, Gurbir S.; Edwards, Peter J.; Olde Venterink, Harry.
Aims and Methods Vascular plants are known to influence the production, transport and oxidation of methane in wetland soils, but these processes are not well understood. Using plants grown in intact peat cores, we compared the influence upon methane emissions of 20 forb and graminoid species from European wetlands. We measured plant-mediated transport of methane (conduit or chimney effect) using a novel agar-sealing technique that prevented methane exchange from the bare soil to the atmosphere.   Important Findings The plant-mediated transport (chimney effect) represented between 30% and almost 100% of the total methane flux, with graminoids exhibiting greater internal transport than forbs. In general, plants with less dense root tissues and a relatively...

Low level of gene flow from cultivated beets (Beta vulgaris L. ssp. vulgaris) into Danish populations of sea beet (Beta vulgaris L. ssp. maritima (L.) Arcangeli)
Provedor de dados: 21
Autores: Andersen, N.S.; Siegismund, H.R.; Meyer, V.; Jørgensen, R.B.
Gene flow from sugar beets to sea beets occurs in the seed propagation areas in southern Europe. Some seed propagation also takes place in Denmark, but here the crop–wild gene flow has not been investigated. Hence, we studied gene flow to sea beet populations from sugar beet lines used in Danish seed propagation areas. A set of 12 Danish, two Swedish, one French, one Italian, one Dutch, and one Irish populations of sea beets, and four lines of sugar beet were analysed. To evaluate the genetic variation and gene flow, eight microsatellite loci were screened. This analysis revealed hybridization with cultivated beet in one of the sea beet populations from the centre of the Danish seed propagation area. Triploid hybrids found in this population were verified...

Effect of sowing date and straw mulch on virus incidence and aphid infestation in organic faba-beans (Vicia faba L.)
Provedor de dados: 21
Autores: Saucke, H.; Juergens, M.; Döring, Th. F.; Lesemann, D.E.; Fittje, S.; Vetten, H.-J.
The effect of sowing date on aphid infestation and the incidence of aphid-transmitted viruses were investigated in organically managed, small-scale field experiments with two faba bean cultivars over 3 years (2002–04). As an additional factor, strawmulchwas applied in 2 of the 3 years shortly before the start of vector activity in May. Virus incidence was determined using enzyme-linked immunosorbent assay and immunoelectron microscopy. Aphid flight activity was monitored using standard yellow water traps. Bean colonising aphids were assessed throughout the vegetation period by counting the number of plants infested with Acyrthosiphon pisum, Megoura viciae and Aphis fabae. Pea enation mosaic virus and bean yellow mosaic virus were the most abundant...

Effects of green manure storage and incorporation methods on nitrogen release and N2O emissions after soil application
Provedor de dados: 21
Autores: Carter, Mette S.; Sørensen, Peter; Petersen, Søren O.; Ma, Xiuzhi; Ambus, Per.
More efficient use of green manure-derived nitrogen (N) may improve crop yields and reduce environmental impacts in stockless organic arable farming. In this 3-month incubation study, we tested a new strategy where green manure leys are harvested and preserved until the following spring either as compost mixed with straw (grass-clover:straw, 4:1, w:w) or as silage of harvested ley biomass. Grass-clover compost or silage was soil-incorporated by either simulated ploughing (green manure placed at 15 cm depth) or harrowing (green manure mixed into the upper 5-cm soil horizon) in order to assess treatment effects on net release of plant-available N, nitrous oxide (N2O) fluxes, and soil respiration. Grass-clover silage provided the highest net N release with...

Effect of feeding fermentable fibrerich feedstuffs on meat quality with emphasis on chemical and sensory boar taint in entire male and female pigs
Provedor de dados: 21
Autores: Hansen, L.L.; Stolzenbach, S.; Jensen, J.A.; Henckel, P.; Hansen-Møller, J.; Syriopoulos, K.; Byrne, D.V.
Skatole, androstenone and other compounds such as indole cause boar taint in entire male pork. However, female pigs also produce skatole and indole. The purpose of this experiment was to minimise boar taint and increase overall impression of sensory quality by feeding entire male and female pigs with fibrerich feedstuffs. The pigs have been fed three organic diets for either 1 or 2 weeks prior to slaughter of which two diets contained different fermentable fibre-rich feedstuffs – 10–13.3% dried chicory roots or  25% blue lupines. These two treatments were compared with pigs fed with an organic control diet for either 1 or 2 weeks prior to slaughter. Lupines significantly reduced skatole in blood and backfat for both genders after 1 week. Moreover, lupines...

Carbohydrate dynamics in roots and rhizomes of Cirsium arvense and Tussilago farfara
Provedor de dados: 21
Autores: Nkurunziza, Libère; Streibig, Jens Carl.
The information of the source-sink dynamics of carbohydrates during early growth can indicate when perennial weeds are most vulnerable to mechanical control. In this study, carbohydrate contents in the roots or rhizomes of two noxious perennial weeds, Cirsium arvense and Tussilago farfara, and basipetal translocation of photo-assimilates were measured. We used HPLC for carbohydrate measurements and 14C labelling to follow the translocation of photo-assimilates during the early growth. These measurements were related to leaf number and leaf area. Fructan and fructose changed significantly over the experimental periods. Fructan for both species was greatest within two weeks after planting 5-cm long root/rhizome fragments and declined thereafter. After two...

Provedor de dados: 21
Autores: Matos, Eduardo da Silva; Mendonça, Eduardo de Sá; Cardoso, Irene Maria; Lima, Paulo César de; Freese, Dirk.
Leguminous plants used as green manure are an important nutrient source for coffee plantations, especially for soils with low nutrient levels. Field experiments were conducted in the Zona da Mata of Minas Gerais State, Brazil to evaluate the decomposition and nutrient release rates of four leguminous species used as green manures (Arachis pintoi, Calopogonium mucunoides, Stizolobium aterrimum and  Stylosanthes guianensis) in a coffee agroforestry system under two different climate conditions. The initial N contents in plant residues varied from 25.7 to 37.0 g kg-1 and P from 2.4 to 3.0 g kg-1. The lignin/N, lignin/polyphenol and(lignin+polyphenol)/N ratios were low in all residues studied. Mass loss rates were highest in the first 15 days, when 25 % of the...

Root biomass in cereals, catch crops and weeds can be reliably estimated without considering aboveground biomass
Provedor de dados: 21
Autores: Hu, Teng; Sørensen, Peter; Wahlström, E.M.; Chirinda, Ngonidzashe; Sharif, Behzad; Li, Xiaoxi; Olesen, Jørgen E.
Reliable information on belowground plant biomass is essential to estimate belowground carbon inputs to soils. Estimations of belowground plant biomass are often based on a fixed allometric relationship of plant biomass between aboveground and belowground parts. However, environmental and management factors may affect this allometric relationship making such estimates uncertain and biased. Therefore, we aimed to explore how root biomass for typical cereal crops, catch crops and weeds could most reliably be estimated. Published and unpublished data on aboveground and root biomass (corrected to 0–25 cm depth) of cereal crops (wheat and barley), catch crops and weeds were collected from studies in Denmark. Leave one out cross validation was used to determine...

Detecting key parasitoids of lepidopteran pests by multiplex PCR
Provedor de dados: 21
Autores: Traugott, Michael; Zangerl, Petra; Juen, Anita; Schallhart, Nikolaus; Pfiffner, Lukas.
The use of diagnostic polymerase chain reaction (PCR) is a valuable approach to study host–parasitoid interactions. It circumvents problems inherent to rearing parasitoids from Weld-collected hosts or host dissection. Here, we present a PCR-based detection method for Diadegma semiclausum, Cotesia glomerata, and Cotesia rubecula, which are key parasitoids of the three lepidopteran cabbage pests Plutella xylostella, Pieris brassicae, and Pieris rapae, respectively. Primer pairs for the three parasitoid species and Pl. xylostella were developed: they were used either separately in singleplex PCR or combined in multiplex PCR to (1) screen simultaneously for the two Cotesia species or to (2) detect the parasitoid D. semiclausum and identify its host Pl....

Crop responses to 15N-labelled organic and inorganic nitrogen sources
Provedor de dados: 21
Autores: El-Naggar, Ahmed; El-Araby, Ahmed; de Neergaard, Andreas; Høgh-Jensen, Henning.
A major challenge for low¬-external-input farming systems is to secure the N supply. Lack of synchrony between mineralization of organic N sources and plant N requirements is causing many growers to use different techniques to overcome this problem. One of these techniques is the application of soluble water extracts of different farm residues and plants. A field study was conducted to study the crop uptake of applied 15N-labeled alfalfa and clover extracts as compared to the N uptake from15N-glycine and three levels of 15N-(NH4)2SO4. The results show that total N accumulation in the field crops, squash and lettuce, was primarily affected by the amount of added N (P&lt;0.05) and not by the form in which the N was applied (P&gt;0.05).

Autores: Alrøe, Hugo Fjelsted; Moller, Henrik; Læssøe, Jeppe; Noe, Egon.
The focus of the Special Feature on “Multicriteria assessment of food system sustainability” is on the complex challenges of making and communicating overall assessments of food systems sustainability based on multiple and varied criteria. Four papers concern the choice and development of appropriate tools for making multicriteria sustainability assessments that handle built-in methodological conflicts and trade-offs between different assessment objectives. They underscore the value of linking diverse methods and tools, or nesting and stepping their deployment, to help build resilience and sustainability. They conclude that there is no one tool, one framework, or one indicator set that is appropriate for the different purposes and contexts of...

Soil carbon storage and yields of spring barley following grass leys of different age
Provedor de dados: 21
Autores: Christensen, B.T.; Rasmussen, J.; Eriksen, J.; Hansen, E.M.
The inclusion of leys in arable cropping is generally found to improve soil fertility. The effect of leys depends on their botanical composition and management, but the significance of individual management factors remains confounded in most studies. We quantified the effects of one- to six-year-old pure grass leys on soil C (0-20 cm) and yields of three subsequent test crops of spring barley (Hordeum vulgare) under-sown with Italian ryegrass (Lolium perenne). Each ley was a mixture of four grass species (Lolium perenne, Festuca pratensis, Phleum pratense, Poa pratensis), exposed to three to four cuts annually. Only mineral fertilizers were applied (225 kg N ha-1 yr-1). The yield of barley was tested at six rates of N fertilizer (0 to 150 kg N ha-1). The...

Ikke-medicinsk kontrol af indvoldsorm i grise
Provedor de dados: 21
Autores: Mejer, Helena; Roepstorff, Allan.
Der er generelt en højere forekomst af indvoldsorm i økologiske grise i forhold til indendørs grise. For at reducere forekomsten af indvoldsorm kan man bl. a. sørge for at nye dyr er parasitfri, holde en moderat belægningsgrad, samgræsse søer med kvier, bruge næsering, ændre foderets  sammensætning og fodre grisene med rovsvamp. Derudover anbefales det at man benytter foldskifte, så man fjerner grisene fra smittekilden (ormenes fritlevende larver og æg). Et større markforsøg har vist at larver af knudeormen overlever dårligt i det fri og må overordnet anses for at være et mindre problem.  Æg af spolormen og piskeormen kan derimod overleve i flere år selvom især pisleormens æg kan være lang tid om at blive infektive for grise. Grises optag af æg af...

Autores: Gatti, Matteo; Garavani , A; Cantatore, A; Poni, Stefano.
Background and Aims: The increasing interest by the wine market in sparkling white wines challenges how the  desired grape composition can be achieved under the pressure of global warming. The aim of the present study was  to assess the viability of summer pruning as a tool to pilot ripening towards desired compositional patterns.  Methods and Results: Ortrugo was subjected to basal leaf removal applied either at pre-flowering (ELR) or in  lag-phase (LLR) and to bunch thinning (BT; removal of 50% of crop at lag-phase) in comparison with untreated  control (C). Treatments induced large variation in bunch mass (30% less in ELR vs BT), yield per vine (37 and 21%  less in BT and ELR vs C) and total soluble solids at harvest (BT scored 2.9°Brix higher than that...

Provedor de dados: 21
Autores: Daniel, Claudia; Baroffio, Catherine.
Die Kirschessigfliege Drosophila suzukii wurde 2008 nach Europa eingeschleppt und hat im Mittelmeerraum bereits für starke Schäden gesorgt. Im letzten Sommer wurde der neue Schädling erstmals auch in der Schweiz nachgewiesen. Die Fliegen befallen alles Weichobst (Beeren, Kirschen, Trauben) sowie viele Wildfrüchte. In diesem Jahr sollten alle sensiblen Kulturen mit Apfelessig-Fallen überwacht werden. Zur Befallsvorbeugung werden der Einsatz von engmaschigen Netzen, Massenfang mit Fallen sowie das Vernichten befallener Früchte empfohlen. Das BLW hat den Einsatz von Spinosad und Pyrethrum unter Auflagen bewilligt.

The World Trade Organization and Organic Food Trade: Potential for Restricting Protectionism?
Provedor de dados: 21
Autores: Daugbjerg, Carsten.
This paper outlines the global food regulation regime and its institutions, focussing upon the way in which these address organic food trade. While the WTO Agreements have rules for scientifically based policy measures adopted to protect human, animal or plant health or life, there is some disagreement on whether the WTO’s Agreement on Technical Barriers to Trade (addresses food labelling) covers production standards based on ethical values such as those defining organic food standards. Another problem is that two sets of international standards for organic food exist - the Codex Alimentarius guidelines and the standards of the International Federation of Organic Agriculture Movements (IFOAM). Finally, many certification bodies are private organisations...

Propositions for public policies and dissemination of organic farming based upon spatial analyses / Réflexion à partir d’une analyse spatialesur les politiques de soutien et la diffusion de l’agriculture biologique
Provedor de dados: 21
Autores: Allaire, Gilles; Cahuzac, Eric; Maigné, E; Poméon, Thomas; Simioni, M.
Building on three studies conducted on the spatial diffusion of organic farming (OF) in France, the objective of this article is to provide analysis on incentives and obstacles for the development of OF. What restrains the OF adoption is represented by three types of risks (agronomic, economic and moral) which reduce the propensity to convert to organic farming. Our work is based on national data bases on certified farms in 2010 and beneficiaries of aid for conversion to organic farming between 1993 and 2010. If these data do not make it possible to analyse the motivations at the individual level, they provide original findings by their completeness and the mobilization of different spatial and temporal scales, and a set of tools for exploratory and...

Effects of 4 tillage systems on soil structure and soil microbial biomass in organic farming.
Provedor de dados: 21
Autores: Vian, Jean François; Peigné, Joséphine; Chaussod, Rémi; Roger-Estrade, Jean.
Tillage modifies soil structure and crop residue distribution and in turn affects the ability of soil micro-organisms to degrade soil organic matter and release nutrients for crop growth. In organic farming, soil microbiological activity is of primary importance as nutrient supply is mainly dependent on the degradation of soil organic matter by soil micro-organisms. The aim of this work was therefore to study, in organic farming, the effects of four tillage systems [mouldboard ploughing (MP), shallow mouldboard ploughing (SMP), reduced tillage (RT) and shallow soil tillage (ST)] on soil structure, soil microbial biomass (SMB) and its potential activity (Cmin) during the first year following the treatments. To study simultaneously the effects of soil...

Cross vane funnel bucket traps with water and detergent captured significantly more A. rubi than sticky traps. L. rugulipennis catches were higher in the cross vane traps, but catches were impeded by the bee excluder grid. There were fewer of the target pest species captured on sticky traps and these devices tended to capture significantly more by-catch (e.g. Diptera) including beneficial insects, e.g. spiders and Carabidae. In the second experiment, the height of the green cross vane had no effect on the numbers of male L. rugulipennis trapped in the funnel traps. However, the higher cross vanes captured more coccinelids and opiliones. In the A. rubi trials there were significantly more individuals in the full height cross vane compared to the half-height...

Organic livestock production: an emerging opportunity with new challenges for producers in tropical countries
Provedor de dados: 21
Autores: Chander, Mahesh; Bodapati, Subrahmanyeswari; Mukherjee, Reena; Kumar, Sanjay.
Agrochemicals, veterinary drugs, antibiotics and improved feeds can increase the food supply while minimising production costs in various livestock production systems around the world. However, these days, quality-conscious consumers are increasingly seeking environmentally safe, chemical-residue-free healthy foods, along with product traceability and a high standard of animal welfare, which organic production methods are said to ensure. Organic production is not only a challenge for producers in developing countries, it offers new export opportunities as well. Organic agriculture is practised by 1.8 million producers in 160 countries, and production of organically grown food continues to increase steadily by 15% per year. Most tropical countries are now...

Autores: Rehberger, Brita; Bütikofer, Ueli; Bisig, Walter; Collomb, Marius.
There is a growing demand among consumers for food products with natural nutritional-physiological advantages over comparable conventional products. As part of an EU project, a process using dry fractionation is evaluated that enables the targeted lowinput enrichment of conjugated linoleic acids (CLA) in milk fat. Furthermore, the distribution of CLA isomers in the fat fractions was analysed. In the olein fraction for highland butter a CLA enrichment of 15.3% was obtained.  The yield of the CLA rich olein fraction was 44.5% of the total amount of olein and stearin. There were significant increases during the first fractionation step of highland butter for the concentration of the CLA isomer cis-9, trans-11 (P £ 0.05) and during the second fractionation...

Subsoil loosening in a crop rotation for organic farming eliminated plough pan with mixed effects on crop yield
Provedor de dados: 21
Autores: Olesen, Jørgen E.; Munkholm, Lars J.
Compacted subsoil may reduce root growth with resulting effects on plant uptake of water and nutrients. In organic farming systems subsoil loosening may therefore be considered an option to increase nutrient use efficiencies. We investigated the effect of subsoil loosening with a Paraplow to c. 35 cm depth in an organic farming experiment at Foulum (loamy sand) and Flakkebjerg (sandy loam) in Denmark. In each of the years 2000 to 2004 one half of four plots per site were loosened in the autumn in a young grass-clover crop established by undersowing in spring barley. The grass-clover was grown for a year as a green manure crop and followed by winter wheat, lupin:barley and spring barley in the following three years. On-land ploughing was used for all these...

Farmers’ reasons for deregistering from organic farming
Provedor de dados: 21
Autores: Koesling, Matthias; Løes, Anne-Kristin; Flaten, Ola; Kristensen, Niels Heine; Hansen, Mette Weinreich.
Every year since 2002, 150 to 200 farmers in Norway have deregistered from certified organic production. The aim of this study was to get behind these figures and improve our understanding of the reasoning leading to decisions to opt out. Four cases of deregistered organic farmers with grain, sheep, dairy or vegetable production were selected for in-depth studies. The cases were analysed from the perspective of individual competencies and the competencies available in the networks of the selected organic farmers. Besides the conspicuous reasons to opt out of certified organic farming, such as regulations getting stricter over time and low income, personal reasons such as disappointment and need for acceptance were also important. This shows that hard...

Autores: Krieger, Margret; Hoischen-Taubner, Susanne; Emanuelson, Ulf; Blanco-Penedo, Isabel; De Joybert, Manon; Duval, Julie; Sjöström, Karin; Jones, Jones J.; Sundrum, Albert.
Production diseases, such as metabolic and reproductive disorders, mastitis, and lameness, emerge from complex interactions between numerous factors (or variables) but can be controlled by the right management decisions. Since animal husbandry systems in practice are very diverse, it is difficult to identify the most influential components in the individual farm context. However, it is necessary to do this to control disease, since farmers are severely limited in their access to resources, and need to invest in management measures most likely to have an effect. In this study, systemic impact analyses were conducted on 192 organic dairy farms in France, Germany, Spain, and Sweden in the context of reducing the prevalence of production diseases. The impact...

From field to table? The marketing of organic products in Norway
Provedor de dados: 21
Autores: Jervell, A.M.; Borgen, S.O.; Flaten, O.
While 3 percent of the fields in Norway are grown organically in the advent of the 21st century, only a small share of the resulting products reaches the consumers as organic food. A number of factors can explain the relative lack of success of organic products through the value chain. Lack of differentiation from conventional foods may discourage consumers. Extra costs limit the interest of processors and retailers.  The political decisions and subsidies are directed at production, and have few direct effects on the organization of the value chain.   The marketing of organic products has followed different strategies. Organic milk is handled through the national dairy cooperative, and around forty percent is sold as organic varieties of conventional...

Farmland biodiversity and agricultural management on 237 farms in 13 European and two African regions. Data Paper.
Provedor de dados: 21
Autores: Lüscher, Gisela; et al.,  many.
Farmland is a major land cover type in Europe and Africa and provides habitat for numerous species. The severe decline in farmland biodiversity of the last decades has been attributed to changes in farming practices, and organic and low-input farming are assumed to mitigate detrimental effects of agricultural intensification on biodiversity. Since the farm enterprise is the primary unit of agricultural decision making, management-related effects at the field scale need to be assessed at the farm level. Therefore, in this study, data were collected on habitat characteristics, vascular plant, earthworm, spider, and bee communities and on the corresponding agricultural management in 237 farms in 13 European and two African regions.

Økologisk dyrkningssystem til tomat
Provedor de dados: 21
Autores: Sørensen, Seniorforsker Jørn Nygaard; Thorup-Kristensen, Forskningsleder Kristian.
Ved produktion af tomater er der behov for tilførsel af store mængder gødning. Ved økologisk dyrkning kan tilførsel af store mængder organisk gødning medføre risiko for udvaskning. Når planter år efter år dyrkes i den samme jord i væksthus er der en risiko for angreb af jordbårne sygdomme; en risiko som ikke kan forebygges ved sædskifte. Et nyudviklet dyrkningssystem ved DJF Årslev har vist at disse problemer kan undgås. Dyrkningssystemet udnytter fordelene ved både dyrkning direkte i jord og dyrkning i afgrænsede bede. Resultaterne fra forsøget viser at det er muligt at dyrke tomat og opnå helt tilfredsstillende udbytter ved dyrkning i kompost i halvåbne bede hvor det er muligt at recirkulere overskudsvand og genanvende komposten som...

Animal health planning activities are not always providing a satisfactory positive impact on herd health and welfare. Moreover, evaluating the impact of advisory programmes is complex due to multiple interacting elements that influence its outcome. Therefore, measuring solely health outcomes is not sufficient: the whole process of the implementation and use of such programmes should be evaluated. In order to evaluate the impact of an intervention with a Herd Health and Production Management (HHPM) programme a process evaluation framework was designed and used. The intervention involved 20 organic dairy cattle farmers and their advisors, in both France and Sweden. In both countries 20 organic dairy farms were selected as control herds.

Provedor de dados: 21
Autores: Chirinda, N.; Olesen, J.E.; Porter, J.R.; Schjønning, P.
Organic and conventional farming practices differ in the use of several management strategies, including use of catch crops, green manure, and fertilization, which may influence soil properties, greenhouse gas emissions and productivity of agroecosystems. An 11-yr old field experiment on a sandy loam soil in Denmark was used to compare several crop rotations with respect to a range of physical, chemical and biological characteristics related to carbon (C) and nitrogen (N) flows. Four organic rotations and an inorganic fertilizer-based system were selected to evaluate effects of fertilizer type, catch crops, of grass-clover used as green manure, and of animal manure application. Soil was sampled from winter wheat and spring barley plots in Sept 2007, April...

Utilising scripting language for unmanned and automated guided vehicles operating within row crops
Provedor de dados: 21
Autores: Jørgensen, Rasmus N.; Nørremark, Michael; Sørensen, Claus G.; Andersen, Nils Axel.
A flexible high-level control language is an important element in the ongoing task of introducing automated guided vehicles (AGV) to new application domains. A new application domain is row crops, where small AGV’s will perform weed control around individual crop plants. This paper defines the requirements and scope of a process- and behaviour-based scripting language needed to control the weeding AGV in an agricultural row crop. The goal is to traverse and cover the whole field with no human auxiliary input during the field operation. The basis is the transparent and tactical real-time control language (CL) for small mobile robots (SMR). This SMR-CL has been modified to include some necessary motion commands and a supplemental supervisory function to...

Microbial carbohydrates are immediate by-products of microbial metabolism and play an important role in the formation and stabilization of soil structure. The effect of long-term management on soil carbohydrate content and monosaccharide composition was investigated in five. Danish sandy loams under organic and conventional management with animal manure and mineral fertilizers. Hot-water (80°C)extraction was used to measure the distribution and composition of carbohydrates in aggregate size. Carbohydrates released to hot water were determined after hydrolysis as reducing sugars equivalent to glucose. The monosaccharide composition in hot-water extracts was analyzed as the corresponding alditol acetates. Sites with a history of long-term continuos...

People&amp;rsquo;s identity, connection with land, and the adaptation of Indigenous and local knowledge are prerequisites for resilience. Though the Environmental Precautionary Principle (EPP) aims to tackle environmental degradation by privileging the environment in the face of uncertainty, it is not sufficient on its own; it does not take into account the intimate connection between nature and local culture, nor does it prioritize community or cultural wellbeing. We suggest expanding this...

Allocation of added selenium in lettuce and its impact on roots
Provedor de dados: 21
Autores: Simojoki, Asko; Xue, Tailin; Lukkari, Kaarina; Pennanen, Arja; Hartikainen, Helinä.
Allocation of selenium (Se) in lettuce and its impact on root morphology were studied to better understand the growth responses of plants to added Se. Lettuce was grown in vermiculite under controlled growing conditions for seven weeks, and the allocation in the shoots and roots of selenate added in increasing dosages (0, 1, 10, 100, 500 and 1000 µg Se per 3.5-litre pot) as well as morphological variables of the roots were determined. The intermediate additions of 100 and 500 µg Se per pot seemed to produce the highest biomasses, although this was nearly masked by large scatter in the data. The Se contents both in roots and shoots increased roughly proportionally to the amount of Se added. However, at small additions Se was preferentially allocated to...

Grain Characteristics, Chemical Composition, and Functional Properties of Rye (Secale cereale L.) As Influenced by Genotype and Harvest Year
Provedor de dados: 21
Autores: Hansen, H.B.; Møller, B.; Andersen, S.B.; Jørgensen, J.R.; Hansen, Å.
Grain characteristic, chemical composition, and functional properties of rye were measured in 19 different cultivars grown in one location in up to 3 years. The cultivars included 8 adapted hybrids, 7 adapted population cultivars, and 4 nonadapted population cultivars. The results showed a significant influence of both harvest year and genotype on grain characteristics, chemical composition, and functional properties of the grain. Multivariate data analysis confirmed that the variations in the data were explained by yearly and genotype differences. Calculations of variance components showed that the variations in plant height, harvest yield, and protein content were mainly due to genotype differences and to a lesser extent to differences among harvest...

Rhizospheric changes of fungal and bacterial communities in relation to soil health of multi-generation apple orchards
Provedor de dados: 21
Autores: Caputo, F.; Nicoletti , F.; De Luca Picione , F.; Manici, L.
The study focused on changes of rhizosphere microbial communities in apple trees in long-term replanted orchards of Central Europe, aiming at developing cropping practices to mitigate replant problems. It started from the evidence of a previous study which showed that a slight modification  of root-colonizing fungal communities was responsible for a great increase of plant growth in soil samples which had previously been subjected to a gamma-irradiation cycle (25 kGy for 8 h), as compared to that observed in the corresponding untreated native soils.  The study was performed on rhizospheric soil from nine multi-generation apple orchards after a plant growth assay with M9 rootstock plantlets. PCR-DGGE analysis of soil DNA was performed to evaluate fungal and...

Effect of ploughing depth and mechanical soil loading on soil physical properties, weed infestation, yield performance and grain quality in sole and intercrops of pea and oat in organic farming
Provedor de dados: 21
Autores: Gronle, Annkathrin; Lux, Guido; Böhm, Herwart; Schmidtke, Knut; Wild, Melanie; Demmel, Markus; Brandhuber, Robert; Wilbois, Klaus-Peter; Heß, Jürgen.
The effect of ploughing depth and mechanical soil loading on the performance of pea sole crops, oat sole crops and pea–oat intercrops was investigated in field experiments under organic farming conditions at two sites in Germany in 2009 and 2010. The two ploughing depths were short-term shallow ploughing to a soil depth of 7–10 cm and deep ploughing to 25–30 cm. Wheel loads of 26 and 45 kN, which correspond to typical rear wheel loads of field machinery used during sowing operations, were compared to an uncompacted control. Shallow ploughing resulted in a greater penetration resistance in the 14–28 cm soil layer compared to deep ploughing. An increase in mechanical soil loading intensity increased the bulk density and decreased the air capacity in the...

Biologically fixed N2 as a source for the N2O production in a grass clover mixture, measured by 15N2
Provedor de dados: 21
Autores: Carter, Mette S.; Ambus, Per.
The contribution of biologically fixed dinitrogen (N2) to the nitrous oxide (N2O) production in grasslands is unknown. To assess the contribution of recently fixed N2 as a source of N2O and the transfer of fixed N from clover to companion grass, mixtures of white clover and perennial ryegrass were incubated for 14 days in a growth cabinet with a 15N2-enriched atmosphere (0.4 atom% excess). Immediately after labelling, half of the grass-clover pots were sampled for N2 fixation determination, whereas the remaining half were examined for emission of 15N labelled N2O for another eight days using a static chamber method. Biological N2 fixation measured in grass-clover shoots and roots as well as in soil constituted 342, 38 and 67 mg N m-2 d-1 at 16, 26 and 36...

Autores: Elhottová, D.; Koubová, A.; Simek, M.; Cajthaml, T.; Jirout, J.; Esperschuetz, J.; Schloter, M.; Gattimger, A.
The present field study documents substantial changes in the soil microbial community (SMC) and organic matter (SOM) in an upland pasture soil resulting from 10 years of “cattle outdoor over-wintering practice”.  Soils from a long-term investigated pasture area were compared under three different levels of cattle impact (SI – severe, MI – moderate, NI – no impact). Extended polar lipids analysis (PLA) confirmed a qualitatively new microbial community profile and a several-fold increase of the microbial biomass in the impacted soils (SI) compared to the control NI soil. The new SMC was derived from cattle intestine microorganisms, typical by increased content of archaeal phospholipid ether lipids and by new fatty acids indicative for bacterial and fungal...

Nowadays, organically produced products have become more popular than ever and interest in them is still   growing fast. The early blight causal pathogen Alternaria solani has not been considered a great threat to potato in   northern climate conditions in the past and has not been routinely sprayed against. During our study early blight   was evaluated in 2010 and 2011 on the plants of a potato cultivar ‘Reet’ in an organic farming experiment. In our   study, both growing seasons were very favourable for early blight development. Significant differences between   the two cultivation technologies were found (F1,12 = 4.84, p = 0.048). In 2010, the area under disease progress curve   (AUDPC) value was 303 on cover crop (CC) plots and 990 on CC + M (manure)...

Susceptibility of different life stages of Rhagoletis cerasi to entomopathogenic fungi. The effects of six fungus strains (Deuteromycotina: Hyphomycetes) on the mortality of different life stages of the European cherry fruit fly, Rhagoletis cerasi Loew (Diptera: Tephritidae), were assessed in a series of laboratory experiments. All fungus strains caused mycoses in larvae and adults of R. cerasi. Virulence however varied considerably between the strains. Effects on L3-larvae were negligible; none of the fungus strains caused mortalities of more than 25% of larvae. Adults by contrast were highly susceptible to fungal infection. Beauveria bassiana and Paecilomyces fumosoroseus caused 90 to 100% mortality and had a strong influence on fecundity. Metarhizium...

Fine nylon mesh fences (135 cm high) with varying lengths of downward-sloping collection overhangs were evaluated for efficacy in excluding the female cabbage flies Delia radicum (L.) from plots of radish, Raphanus sativus (L.). During three trials conducted in 1994 and 1995, fences without overhangs, fences with 12.5-cm overhangs, or fences with 50-cm overhangs were tested against fences with standard 25-cm overhangs and unfenced control plots. In fenced plots with standard 25-cm overhangs, the mean number of D. radicum females caught on yellow sticky traps placed within plots was 85% less than those caught in corresponding control plots. The mean numbers of D. radicum females caught in fenced enclosures with no overhangs, 12.5-cm overhangs, or 50-cm...

Review: Towards the agroecological management of ruminants, pigs and poultry through the development of sustainable breeding programmes. II. Breeding strategies
Provedor de dados: 21
Autores: Phocas, F.; Belloc, Catherine; Bidanel, J.; Delaby, Luc; Dourmad, J. Y.; Dumont, B.; Ezanno, Pauline; Fortun-Lamothe, L.; Foucras, G.; Frappat, Brigitte; Gonzalez-Garcia, E.; Hazard, D.; Larzul, C.; Lubac, S.; Mignon-Grasteau, S.; Moreno, C. R.; Tixier-Boichard, M.; Brochard, M.
Agroecology uses ecological processes and local resources rather than chemical inputs to develop productive and resilient livestock and crop production systems. In this context, breeding innovations are necessary to obtain animals that are both productive and adapted to a broad range of local contexts and diversity of systems. Breeding strategies to promote agroecological systems are similar for different animal species. However, current practices differ regarding the breeding of ruminants, pigs and poultry. Ruminant breeding is still an open system where farmers continue to choose their own breeds and strategies. Conversely, pig and poultry breeding is more or less the exclusive domain of international breeding companies which supply farmers with hybrid...

The constitution of trust: Function, configuration and generation of trust in Alternative Food Networks
Provedor de dados: 21
Autores: Thorsøe, Martin H.; Kjeldsen, Chris.
Alternative Food Networks (AFN) is often mentioned as a way to reconfigure the link between producers and consumers and build trust in the food system. This article explores the function, configuration and generation of trust in AFNs. The structure is twofold. First we discuss the theoretical underpinnings of trust, in both recent AFN literature and in sociology, and develop a conceptual framework for analyzing trust in AFN. Second, we explore the function, configuration and generation of trust in the Food Communities of Copenhagen and Aarhus (in Danish: “Fødevarefællesskaberne”). The Food Communities are a network of urban consumers sourcing organic products from regional producers. Empirically, the article demonstrates that trust functions as a mechanism...

Roughages for Growing Pigs, with Emphasis on Chemical composition, Ingestion and Faecal Digestibility
Provedor de dados: 21
Autores: Carlson, D.; Lærke, H.N.; Poulsen, H.D.; Jørgensen, Henry.
In 2 experiments, 10 gilts (30 kg initial liveweight) were given a basal diet with fresh or frozen/thawed clover-grass, clover-grass silage or whole-crop pea-barley silage. The faecal digestibility of gross energy (GE), DM, organic matter (OM), dietary fibre (DF) and CP were measured. The 3 roughages, leaves and stems of clover-grass and the basal diets were also tested for in vitro OM digestibility. Roughage intake was similar in both experiments and the average proportion of roughage ingested was 18-19% of DM. There were no differences between fresh and frozen/thawed clover-grass nutrient digestibility values. Glucose (cellulose) and xylose were the main constituents of the non-starch polysaccharides (NSP) in the roughages, with whole-crop pea-barley...

Autores: Vignozzi, N.; Andrenelli, M.C.; L'Abate, G.; Pellegrini, S.
This paper aims to show the effectiveness of different soil management strategies for improving soil structure in degraded areas within two vine farms inTuscany(Italy). The management practices adopted were: Composted organic amendment addition (COMP), Green Manure (GM), Dry mulching (DM) and Control (CONTR). Topsoil samples were taken at the beginning of the trial (2015) and two years later, and analyzed for bulk density (BD) and aggregate stability by wet sieving. The strategies adopted to restore the functionality of degraded vineyard soils diversely affected BD and aggregates stability. In both the farms COMP proved to be the best strategy to reduce BD, while GM and DM gave the best results in terms of aggregate stability increase.

Sustainability and Uncertainty: Bottom-Up and Top-Down Approaches
Provedor de dados: 21
Autores: Jensen, Karsten Klint.
The widely used concept of sustainability is seldom precisely defined, and its clarification involves making up one’s mind about a range of difficult questions. One line of research (Bottom-Up) takes sustaining a system over time as its starting point and then infers prescriptions from this requirement. Another line (Top-Down) takes as its starting point an economical interpretation of the Brundtland Commission’s suggestion that the present generation’s need-satisfaction should not compromise the need-satisfaction of future generations. It then measures sustainability at the level of society and infers prescriptions from this requirement.    These two approaches may conflict, and in this conflict the Top-Down Approach has the upper hand, ethically...

Forbs differentially affect soil microbial community composition and functions in unfertilized ryegrass-red clover leys
Provedor de dados: 21
Autores: Cong, WF; Eriksen, J.
Increasing plant diversity in agroecosystems is proposed to enhance multiple ecosystem services. Adding selected forbs such as caraway (Carum carvi L.) and plantain (Plantago lanceolata L.) to productive grass-clover mixtures can further enhance forage yields, root biomass, uptake of mineral nutrients and improve animal performance. Yet, it remains unclear whether and how adding these forbs to grass-clover mixtures can influence soil microbial communities and associated soil carbon (C) and nitrogen (N) cycling. Based on a three-year grassland experiment varying in species diversity and composition with and without fertilizer application, we determined soil microbial community composition and functions related to C and N cycling under laboratory...

Mit der Halbzeitbewertung der Gemeinsamen Agrarpolitik schlägt die EU-Kommission eine grundsätzlich richtige Richtung ein. Mit neuen, in sich kohärenteren Politikmassnahmen versucht die Kommission die bereits in der Agenda 2000 formulierten Ziele (Wettbewerbsfähigkeit, Ländliche Entwicklung, Nachhaltigkeit) effizienter zu erreichen. Da der ökologische Landbau nicht integrierter Bestandteil der vorgeschlagenen Agrarreform ist, bedarf es eines europäichen Aktionsplanes zur gezielten Förderung des Ökolandbaus.

Autores: Baldivieso-Freitas, Paola; Blanco-Moreno, José M.; Gutiérrez-López, Mónica; Peigné, Joséphine; Pérez-Ferrer, Alejandro; Trigo-Aza, Dolores; Sans, Francesc Xavier.
Earthworms are one of the most important soil macrofaunal groups, and they play a major role in agricultural ecosystems. Agricultural practices, such as reduced tillage, the use of green manures and organic fertilization, can be beneficial for earthworm populations in agricultural systems. However, under a Mediterranean climate, not much is known regarding their response to agricultural management. The aim of this study was to analyse the effects of tillage type, organic fertilization, and green manures on the density and biomass of earthworms in organic arable dryland. The trial was conducted in a four-year crop rotation with a complete factorial design that combined tillage system (mouldboard ploughing vs. chisel), fertilization (composted farmyard...

Sources of nitrogen for winter wheat in organic cropping systems
Provedor de dados: 21
Autores: Petersen, Søren O.; Schjønning, P.; Olesen, Jørgen E.; Christensen, S.; Christensen, B.T.
In organic cropping systems, legumes, cover crops, residue incorporation, and manure application are used to maintain soil fertility, but the contributions of these management practices to soil nitrogen (N) supply remain obscure. We examined potential sources of N for winter wheat (Triticum aestivum L.) in four experimental cropping systems established in 1997 on three soil types. Three of the four systems were under organic management. Topsoil N, depth of the A horizon, and cumulated inputs of N since 1997 were determined at plot level. Labile soil N pools (mineral N, potentially mineralizable N [PMN], microbial biomass N [MBN]) were monitored during two growth periods; at one site, biomass C/N ratios were also determined. Soil for labile N analysis was...

Why farmers should manage the arbuscular mycorrhizal symbiosis
Provedor de dados: 21
Autores: Rillig, Matthias C.; Aguilar‐Trigueros, Carlos A.; Camenzind, Tessa; Cavagnaro, Timothy R.; Degrune, Florine; Hohmann, Pierre; Lammel, Daniel R.; Mansour, India; Roy, Julien; van der Heijden, Marcel G.A.; Yang, Gaowen.
The Tansley review by Ryan &amp; Graham (2018) provided a welcome critical perspective on the role of arbuscular mycorrhizal (AM) fungi in large‐scale industrial agriculture, with a focus on cereals (wheat, Triticum aestivum). They conclude that there is little evidence that farmers should consider the abundance or diversity of AM fungi when managing crops. We welcome many of the points made in the paper, as they give an opportunity for self‐reflection, considering that the importance of AM fungi in agroecosystems is often taken for granted. However, we suggest that it is too early to draw the overall conclusion that the management of AM fungi by farmers is currently not warranted.    We offer the following points to contribute to the discussion. The first...

It has been suggested that conversion to organic farming contributes to soil carbon sequestration, but until now a comprehensive quantitative assessment has been lacking. Therefore, datasets from 74 studies from pairwise comparisons of organic vs. nonorganic farming systems were subjected to metaanalysis to identify differences in soil organic carbon (SOC). We found significant differences and higher values for organically farmed soils of 0.18±0.06% points (mean ± 95% confidence interval) for SOC concentrations, 3.50 ± 1.08 Mg C ha−1 for stocks, and 0.45 ± 0.21 Mg C ha−1 y−1 for sequestration rates compared with nonorganic management. Metaregression did not deliver clear results on drivers, but differences in external C inputs and crop rotations seemed...

Factors in the decision by Swiss farmers to convert to organic farming
Provedor de dados: 21
Autores: Home, Robert; Indermuehle, Annina; Tschanz, Anna; Ries, Elke; Stolze, Matthias.
Demonstrated economic benefits of conversion to organic agriculture, combined with solutions to technical and production-related problems, suggest that farmers in Switzerland should have converted in large numbers to organic production. However, the number of organic farms in Switzerland has remained virtually constant in the last 10 yr, so it appears there are other factors that influence the decision of whether or not to convert. Several studies have sought to identify the factors that influence the decisions by farmers whether or not to convert to organic, but have found a range of factors that appear to be context dependent, while others can be seen as context transcendent, which makes it difficult to draw generalizable conclusions. The aim of this...

Spectral characterisation of red pigment in Italian-type dry-cured ham. Increasing lipophilicity druing processing and maturation
Provedor de dados: 21
Autores: Møller, Jens K.S.; Adamsen, Christina E.; Skibsted, Leif H.
Spectroscopic studies of Parma ham during processing revealed a gradual transformation of muscle myoglobin, initiated by salting and continuing during ageing. Electron spin resonance spectra did, however, conclusively show that the pigment in dry-cured Parma ham at no stage is a nitrosyl complex of ferrous myoglobin as found in brine-cured ham and Spanish Serrano hams. Both near-infra red reflectance spectra of sliced ham and UV/visible absorption spectra of extract of hams, obtained with aqueous buffer or acetone, showed the presence of different red pigments at varying processing stages for both solvents. Especially, the pigment extracted with aqueous buffer exhibited unique spectral features different from those of well-known myoglobin derivatives. At...

Lifestyle, dietary patterns and nutritional status of organic food consumers have rarely been described, while interest for a sustainable diet is markedly increasing. Consumer attitude and frequency of use of 18 organic products were assessed in 54,311 adult participants in the Nutrinet-Santé cohort. Cluster analysis was performed to identify behaviors associated with organic product consumption. Cross-sectional association with overweight/obesity was estimated using polytomous logistic regression. Five clusters were identified: 3 clusters of non-consumers (35%) whose reasons differed, occasional (OCOP, 51%) and regular (RCOP, 14%) organic product consumers. RCOP were more highly educated and physically active than others. They exhibited dietary patterns...

Un sistema di certificazione risk-based per i controlli in agricoltura biologica: un’applicazione tramite Bayesian networks.
Provedor de dados: 21
Autores: Gambelli, Danilo; Solfanelli, Francesco; Zanoli, Raffaele.
The existing method of certification in organic agriculture system, which requires a periodical inspection for all the operators, is inefficient due to the high cost of these controls. A risk based decision support system, that could assist the inspection body during the planning of the annual inspection visits, is advocated to be more cost-effective and efficient. The risk based decision support system is constructed as a Bayesian network; the models incorporate the factors that influence risk of irregularity and analyse their effects by determining probability of non-compliance. Empirical findings using a sample of Italian data on inspection of organic farms, support the idea that the current risk categories used by control bodies in Italy are...

The supply chain and conversion to organic farming in Belgium or the story of the egg and the chicken
Provedor de dados: 21
Autores: Baecke, Eveline; Rogiers, Geert; De Cock, Lieve; Van Huylenbroeck, Guido.
Organic products form a growing segment of the food market. Recent estimates speak about market shares between 1 to 4.25 per cent. In Belgium the share is only 1 per cent, but the market is growing exponentially. Organic farmers in Belgium often have to sell their products as conventional products because of non-efficient marketing systems. Marketing problems are also mentioned as one of the main reasons by conventional farmers for not converting. Most conventional farmers are not only rather sceptical about the long-term perspectives of getting a price premium for organic products, but consider the organisation of the supply chain as one of the main sources of uncertainty and therefore as a constraint for conversion. Therefore more efforts should be made...

The effect of stubble tillage and primary tillage on population dynamics of Canada Thistle (Cirsium arvense) in organic farming
Provedor de dados: 21
Autores: Pekrun, Carola; Claupein, Wilhelm.
Canada Thistle (Cirsium arvense) is a widespread weed in organic farming. It is difficult to control and in many farming enterprises there is a tendency of increase. Reduced frequency and intensity of tillage may be one reason for increasing problems. We studied the impact of stubble tillage and primary tillage on population-dynamics of C. arvense. In this paper results are presented of two field experiments at the ‘Experimental Station for Organic Farming Kleinhohenheim’, one field experiment on ‘Goldener Acker’ at Hohenheim and 19 experiments on organic farms south of Stuttgart. The experiments were carried out between 1998 and 2003.   Results show that inversion in autumn or winter is vital for the control of C. arvense. In an experiment testing various...

Autores: Lammerts van Bueren, Edith T.; Struik, Paul C.; Eekeren, Nick van; Nuijten, Edwin.
How the growing world population can feed itself is a crucial, multi-dimensional problem that goes beyond sustainable development. Crop production will be affected by many changes in its climatic, agronomic, economic, and societal contexts.  Therefore, breeders are challenged to produce cultivars that strengthen both ecological and societal resilience by striving for  six international sustainability targets: food security, safety and quality; food and seed sovereignty; social justice;  agrobiodiversity; ecosystem services; and climate robustness. Against this background, we review the state of the art in plant  breeding by distinguishing four paradigmatic orientations that currently co-exist: community-based breeding, ecosystem-based  breeding,...

Collective action framing genetic engineering resistance in New Zealand
Provedor de dados: 21
Autores: Tucker, C.
The genetic engineering resistance movement in New Zealand constructed strategic and meaningful interpretations of why the genetic engineering technique is problematic and what can be done about it. There are four central interpretations – explored here as collective action frames – that were used by key movement activists in their mobilisation activities. These four frames describe genetic engineering as ‘involving a wide range of issues’, ‘risky’, ‘unnatural’ and as ‘all about the ownership of life’. The characteristics of these frames are explained in this paper, along with an analysis of why it is that activists were able to achieve widespread resonance through their deployment of them. The successful framing and articulation of movement grievances is...

Autores: Christensen, Anne Deen; Kádár, Zsófia; Oleskowicz-Popiel, Piotr; Thomsen, Mette Hedegaard.
Ethanol production by K. marxianus in whey from organic cheese production was examined in batch and continuous mode. The results showed that no pasteurization or freezing of the whey was necessary and that K. marxianus was able to compete with the lactic acid bacteria added during cheese production. The results also showed that, even though some lactic acid fermentation had taken place prior to ethanol fermentation, K. marxianus was able to take over and produce ethanol from the remaining lactose, since a  significant amount of lactic acid was not produced (1–2 g/l). Batch fermentations showed high ethanol yield (*0.50 g ethanol/g lactose) at both 30ºC and 40ºC using low pH (4.5) or no pH control. Continuous fermentation of nonsterilized whey was performed...

Managing Sonchus arvensis using mechanical and cultural methods
Provedor de dados: 21
Autores: Vanhala, Petri; Lötjönen, Timo; Hurme, Timo; Salonen, Jukka.
Perennial sow-thistle (Sonchus arvensis L.) represents an increasing problem in Finland. Options for mechanical and cultural control of S. arvensis were studied in a field experiment on clay soil under organic production. The experiment consisted of different crop sequences: spring cereal (barley, Hordeum vulgare L., in 2001, oats, Avena sativa L., in 2002) with or without inter-row hoeing and/or stubble cultivation, bare fallow, fibre hemp (Cannabis sativa L.), and ley with mowing. In 2003 the entire field was sown to spring wheat. Crop plant and Sonchus shoot density and dry mass prior to cereal harvest and crop yield were assessed. The control effect was rated: bare fallow &gt; ley &gt; cereal with or without inter-row hoeing &gt; poor growth fibre...

Potential and limitations of plant virus epidemiology: lessons from the Potato virus Y pathosystem
Provedor de dados: 21
Autores: Döring, Thomas F.
Abstract Plant virus epidemiology provides powerful tools to investigate key factors that contribute to virus epidemics in agricultural crops. When successful, epidemiological approaches help to guide decisions regarding plant protection strategies. A recent example is epidemiological research on Potato virus Y (PVY) in Finnish seed potato production; this study led to the dentification of the main PVY vector species and helped to determine the timing of virus transmission. However, pathosystems rarely allow research to produce such clear-cut results. In fact, the notorious complexity of plant virus pathosystems, with multiple interactions between virus, vector, plant and environment, makes them often impenetrable even for advanced epidemiological models....

Lord Northbourne, the man who invented organic farming, a biography
Provedor de dados: 21
Autores: Paull, John.
It was Lord Northbourne (Walter James; 1896-1982) who gifted to the world the term ‘organic farming’. His 1940 book Look to the Land is a manifesto of organic agriculture. In it he mooted a contest of “organic versus chemical farming” which he foresaw as a clash of world views that may last for generations. Northbourne’s ideas were foundational in launching the worldwide organics movement, and the book was a turning point in his own life. This biography relies on primary sources to draw a picture of Lord Northbourne. He was a very shy man, a talented artist, a capable linguist, a keen sportsman and an Olympic silver medallist, a graduate and lecturer in agriculture of the University of Oxford, a lifelong farmer, he was profoundly spiritual, an accomplished...

Fresh fruit jointly to vegetables are an essential component of a healthy diet, able to decrease the risk of cardiovascular diseases and cancer. In the last years, their consumption has continued to grow rapidly linked to the increased public awareness of their health benefits, even if it remains below the recommended daily intake in many countries, due to barriers such as complacency and lack of willpower to change the diet. The attributes of berries, like chemical-physical and nutritional characteristics, microbial contamination, chemical contaminants as well as sensorial properties represent some very important quality parameters that must be determined in order to establish the quality of berries after ripening and during storage, until they reach...

Die (hohen) Preise für Öko-Lebensmittel werden von Verbrauchern in nahezu allen Befragungen als bedeutendster Grund angegeben nicht mehr Öko-Lebensmittel zu kaufen. Bei näherer Betrachtung dieses auf den ersten Blick sehr einleuchtenden Arguments ergeben sich allerdings zahlreiche Fragen. Zum einen weisen einige, allerdings schon ältere Untersuchungen darauf hin, dass die tatsächlichen Preiskenntnisse von Verbrauchern bei Öko-Lebensmitteln relativ gering sind. Auf der anderen Seite finden sich in jüngster Zeit auch Hinweise, dass Öko-Lebensmittel teilweise nur geringfügig teurer seien als viele konventionelle Lebensmittel.

Autores: Kas, Martin; Matejkova, Stepanka; Divis, Jiri.
Yields and qualitative parameters of four varieties of table potatoes, such as starch content and tuber size categories, were evaluated in organic and conventional farming during a three-year field experiment in Lukavec, Czech Republic. Potatoes were cultivated after two preceding crops and subjected to analyses. Based on analyses, significant difference between the conventional system and the organic system in the tuber yields was found. Further, the potato yield can be affected year, growing system and preceding crops. A significant influence of the preceding crops upon potato yields was proved. The potato yield after clover was about 8 t.ha-1 greater than after wheat amended with manure. No significant differences in yield were observed among the...

Tidligere ble god fysisk helse, høy tilvekst/ytelse og god fruktbarhet ansett å være ensbetydende med at dyret hadde det bra. I dag regnes ikke dette som tilstrekkelige indikatorer. Atferd, stressmestring og ulike uttrykk for dyrs mentale tilstand står sentralt. Negative indikatorer som sjukdom og atferdsforstyrrelser må vurderes, sammen med tilstedeværelse av positive indikatorer som lek og annen trivselsatferd. Denne artikkelen omhandler i hovedsak de delene av velferdsbegrepet som omfatter trivsel og mulighet for naturlig atferd.

In this paper we present effects of four paired agricultural management practices (organic matter (OM) addition versus no organic matter input, no-tillage (NT) versus conventional tillage, crop rotation versus monoculture, and organic agriculture versus conventional agriculture) on five key soil quality indicators, i.e., soil organic matter (SOM) content, pH, aggregate stability, earthworms (numbers) and crop yield. We have considered organic matter addition, no-tillage, crop rotation and organic agriculture as “promising practices”; no organic matter input, conventional tillage, monoculture and conventional farming were taken as the respective references or “standard practice” (baseline). Relative effects were analysed through indicator response ratio...

Ensiling - Wet-storage method for lignocellulosic biomass  for bioethanol production
Provedor de dados: 21
Autores: Oleskowicz-Popiel, Piotr; Thomsen , Anne Belinda; Schmidt, Jens Ejbye.
Ensiling of humid biomass samples wrapped in plastic bales has been investigated as a wet-storage for bioethanol production from three lignocellulosic biomass samples i.e. maize, rye, and clover grass. During the silage process, lactic acid bacteria fermented free sugars to lactic acid, and consequently by lowing pH, inhibiting other microbes to degrade the polysaccharides. Following silage treatment, enzymatic convertibility tests showed that 51.5%, 36.5%, and 41.9% of the cellulose was converted by cellulytic enzymes in ensiled maize, rye, and clover grass, respectively. In addition, tests of SSF (simultaneous saccharification and fermentation) were carried out using combined enzymatic hydrolysis and fermentation with two different microorganisms...

Role of rodents in transmission of Salmonella and Campylobacter
Provedor de dados: 21
Autores: Meerburg, Dr BG; Kijlstra, Prof dr A.
Salmonella and Campylobacter are generally regarded as the most important food-borne pathogens in the world. Reduction or elimination of these pathogens in the first part of the food chain (on the farm) is important to prevent disease among consumers of animal products. In organic farming, elimination becomes more difficult, as food animals are allowed outdoors and have easy access to potential sources of hazardous pathogens. Whilst  rodents are often associated by organic farmers with infrastructural damage and eating or spoiling of stored feed and products, their zoonotic risks are frequently underestimated. They can amplify the number of pathogens in the environment and transfer them to food animals. Thus organic farmers should be aware of the need for...

Autores: GAUJOUR, E.; AMIAUD, B.; FIORELLI, J.-L.; MIGNOLET, C.; COQUIL, X.
The aim of this work was to identify the impact of farming practices on permanent grassland vegetation during the conversion from conventional to organic farming. We considered functional and species diversities in order to compare the different grassland categories based on the farming practices used over a period of six years - five years before conversion and one year after. We identified three categories of grasslands: those generally cut twice a year, those intensely grazed, and those that were used under diversified practices. We showed that grasslands characterised by cutting and low fertilization level have the highest species richness compared to the other two categories (23.2, 16.9 and 17 species, respectively), and the lowest pastoral index...

Tensile strength of soil cores in relation to aggregate strength, soil fragmentation and pore characteristics
Provedor de dados: 21
Autores: Munkholm, Lars; Schjønning, Per; Kay, Bev D.
Tensile failure of soil is desirable in tillage. Soil tensile strength estimates most often are obtained from compression tests of dry aggregates. As tillage is performed under moist conditions, it would be highly relevant to measure tensile strength at high water contents.    Plough-layer soil was sampled in a compacted soil (PAC) and in a non-compacted reference soil (REF). Tensile strength was measured in a new direct tension test using undisturbed soil cores (4.45 cm in diameter and 5.00 cm in height) adjusted to either -50 or -100 hPa matric potential. The air-filled pore space, a, was determined from water retention measurements. Air permeability, Ka, was determined at -30, -100 and -300 hPa matric potentials and from these measurements an index of...

Methane transport and emissions from soil as affected by water table and vascular plants
Provedor de dados: 21
Autores: Bhullar, Gurbir S.; Iravani, Majid; Edwards, Peter J.; Olde Venterink, Harry.
Background: The important greenhouse gas (GHG) methane is produced naturally in anaerobic wetland soils.  By affecting the production, oxidation and transport of methane to the atmosphere, plants have a major influence upon the quantities emitted by wetlands. Different species and functional plant groups have been shown to affect these processes differently, but our knowledge about how these effects are influenced by abiotic factors such as water regime and temperature remains limited. Here we present a mesocosm experiment comparing eight plant species for their effects on internal transport and overall emissions of methane under contrasting hydrological conditions. To quantify how much methane was transported internally through plants (the chimney...

Aphid (Homoptera: Aphididae) accumulation and distribution near fences designed for cabbage fly (Diptera: Anthomyiidae) exclusion
Provedor de dados: 21
Autores: Bomford, M.K.; Vernon, R.S.; Pats, Peeter.
Aphids accumulate near exclusion fences designed to intercept Delia radicum (L.) movement into fields. Aphid accumulations increase with fence height, but are not affected by fence overhang length. Overall aphid levels are higher in small (4.3 x 4.3 m) enclosed plots than in unenclosed plots. Enclosing large (38 x 38 m) plots does not alter overall aphid catches, but does alter aphid distribution within enclosures. In large enclosures aphid accumulations are higher at enclosure perimeters than interiors, with the highest accumulations near enclosure corners. This concentric distribution is not observed in unfenced areas, and is not altered by the addition of a trap crop inside an enclosure.

Phosphorus (P) should be recycled from organic wastes as much as possible, and input is needed in stockless organic agriculture. Here we assessed 7 organic residues and compared them to mineral P fertilizer and rock phosphate as fertilizer for barley. P availability in the mixtures and residual P availability were also assessed by DGT. The best availability was found in digested liquid manure followed by wood ash, fish sludge, composted solid manure and composted food waste. Meat and bone meal, the commercially available product ladybug and rock phosphate had low P availability at the same level as no P. Only wood ash had significant P available for the next crop. The pH level of the soil did not affect P availability for any of the P sources. DGT...

Agent-based models provide a powerful tool for integration of multiple drivers of ecological systems, but communication of model results is at the same time constrained by the complexity of the model responses. Here, we systematically modify a digital version of a real landscape to produce a set of model landscapes differing in the degree of heterogeneity and test how different landscapes affect abundance and occupancy of six model animal species in four different management scenarios using an agent-based model framework (ALMaSS). ALMaSS is capable of highly detailed modelling of individuals but the outputs can be complex and...

Preference of organic grown carrots in a rat/mice model
Provedor de dados: 21
Autores: Jørgensen, Henry; Velimirov, Alberta; Paoletti, F.; Halekoh, Ulrich; Lauridsen, Charlotte.
Food preference tests represent an approach in food quality research, taking advantage of the instinctive feeding behavior of animals by allowing them to choose between food  samples. A great number of investigations using laboratory mice/rats concerning essential and/or dangerous contents are based on this method and have shown its effectiveness. The selection of food is influenced to some degree by smell and taste, but mostly by wholesomeness and need. The objective of the present study was to investigate the food preference of carrots from different cultivation systems.

Autores: Nkurunziza, Libère; Andreasen, Christian; Liu, Fulai; Streibig, Jens Carl.
The aim of this study was to investigate the effect of controlled soil water deficits on sprouting and shoot growth of Canada thistle, coltsfoots and quackgrass. A gradient of soil water contents was created by establishing different densities of barley. The plants were harvested 14 days after watering was stopped. On Canada thistle and coltsfoots, relative water content (RWC) in leaves was measured prior to harvest and biomass of all weed shoots were recorded at harvest. In terms of shoot biomass and leaf RWC quackgrass was drought tolerant while coltsfoot was drought sensitive and Canada thistle was between the two. The barley cover crop could have had a competitive effect upon the growth of the weeds; the effect, however, was not detrimental compared to...

Ranking the magnitude of crop and farming system effects on soil microbial biomass and genetic structure of bacterial communities
Provedor de dados: 21
Autores: Hartmann, Martin; Fliessbach, Andreas; Oberholzer, Hans-Rudolf; Widmer, Franco.
Biological soil characteristics such as microbial biomass, community structures, activities, and functions may provide important information on environmental and anthropogenic influences on agricultural soils. Diagnostic tools and detailed statistical approaches need to be developed for a reliable evaluation of these parameters, in order to allow classification and quantification of the magnitude of such effects. The DOK long-term agricultural field experiment was initiated in 1978 in Switzerland for the evaluation of organic and conventional farming practices. It includes three representative Swiss farming systems with biodynamic, bio-organic and conventional fertilization and plant protection schemes along with minerally fertilized and unfertilized...

Leder-følge system til græssende køer
Provedor de dados: 21
Autores: Søegaard, Karen.
Køer, der leverer økologisk mælk, skal i praksis fodres med 100% økologisk foder. Derfor spiller afgræsning en aktuel og vigtig rolle for fodringen.    På Rugballegård ved Danmarks JordbrugsForskning undersøgte vi, om det er muligt at maksimere optagelsen under afgræsning ved at bruge et leder-følge system. Ved udbinding havde vi 12 folde, som i løbet af sæsonen blev udvidet til 18 folde efterhånden som væksten af kløvergræsset blev mindre. Malkekøerne græssede to døgn både dag og nat i hver fold, inden de blev flyttet til næste fold, dvs. systemet er et rationsgræsningsprincip.     Det nye er, at kvierne sammen med goldkøerne fulgte efter. Når køerne havde græsset en fold i to døgn, græssede kvierne og goldkøerne folden de næste to døgn. Køerne, der er...

From image to technology: a multidisciplinary approach for improving the quality of organic bread.
Provedor de dados: 21
Autores: ALESSANDRIN, A.; DESMONTS, M.-H.; CHIRON, H.; DUCASSE, M.
This study is part of a research programme devoted to improving the quality of organic bread. It aims to identify and test prototypes of breads approved by consumers. This is achieved by analysing consumer representations and preferences and placing them within the framework of technological, sensory and nutritional dimensions of the products. The multidisciplinary approach implements an original qualitative approach that combines three consumer focus groups made up of both loyal and occasional consumers, and confrontation sessions with the programme scientific partners. Four prototypes of organic breads have thus been formalised and subsequently tested on a sample of 120 consumers from two sites (Angers and Strasbourg). From an operational point of view,...

The Uptake of Organic Agriculture: A Decade of Worldwide Development
Provedor de dados: 21
Autores: Paull, John.
It has been claimed that organic agriculture is the fastest growing agriculture based industry in the world. The land devoted to organic agriculture worldwide has increased over the past decade from 15.8 million hectares to 37.2 million hectares exhibiting a compounding rate of growth of 8.9% per annum. This paper disaggregates the global growth in organic agriculture land over the past decade using country as the unit of analysis. For each country, two indices of organics sector growth are derived, firstly, the actual hectares increase, and secondly, the hectares-multiplier, that is the factor by which the organic hectares have changed over the decade. Growth over the past decade is presented for 71 countries which taken together account for 35.3 million...

In their letter, Leifeld et al.

This was not the case. We included data from all available pairwise field comparisons between OF and CF identified in the literature. The observed difference in external carbon (C) inputs between OF and CF did not result from a bias in the selection of studies/treatments but was attributable to the fact that the field comparisons we analyzed (2) were not from fertilization experiments but from pairwise farming system comparisons where the design and the underlying treatments reflected the current farming practices in...

Consumer preferences for farmed organic salmon and eco-labelled wild salmon in Denmark1
Provedor de dados: 21
Autores: Ankamah-Yeboah, Isaac; Asche, Frank; Bronnmann, Julia; Nielsen, Max; Nielsen, Rasmus.
Sustainably produced food products have rapidly grown in popularity within the last years. Eco-labeling systems to indicate the environmental sustainability of product have also been implemented in the seafood market, with the MSC label for wild fish as the leading one. However, it is not clear whether consumers really notice the values behind an eco-label and how important these attributes are in their purchasing decision. This study analyzes data from a large household scanner panel to investigate actual consumer purchasing behavior and preferences when faced with competing product attributes such as organic and MSC labeled for salmon in Denmark. To accomplish these objectives and explicitly account for consumer heterogeneity, a mixed logit as well as a...

Autores: Daniel, Claudia; Mathis, Samuel; Feichtinger, Georg.
The European cherry fruit fly, Rhagoletis cerasi (L.) (Diptera: Tephritidae), is the most important pest of sweet cherries in Europe. The aim of our experiments was to develop a new, cost-efficient, lead chromate-free and more eco-friendly trap for monitoring and mass trapping of R. cerasi. Five different-colored yellow panels and three different trap shapes were compared to a standard Rebell® amarillo trap in three experimental orchards in 2012. Trap color F, with a strong increase in reflectance at 500–550 nm and a secondary peak in the UV-region at 300–400 nm, captured significantly more flies than the standard Rebell® amarillo trap. Yellow traps with increased reflectance in the blue region (400–500 nm) were least attractive. Trap shape was of minor...

In agricultural systems with low S inputs, crops rely on the release of S from organic forms in the soil. In the Askov long-term experiments, started in 1894 on both sandy and loamy soils, was investigated the soil S status following long-term application of animal manure and mineral fertilizers in the growing season of 1995.  In a field trial with oil-seed rape (Brassica napus, L.) soil analysis, leaf tissue analysis, yield and S-removal in plant material was used to characterize differences in availability of soil S. One half of all plots had 63 kg S/ha as gypsum applied. Fertilization with animal manure or NPK fertilizer increased the content of soil organic C compared with unfertilized plots. This increase was followed by a similar  build-up of organic...

Increasing concentrations of arsenic and heavy metals in agricultural soils are becoming a growing problem in industrialized countries. These harmful elements represent the basis of a range of problems in the food chain, and are a potential hazard for animal and human health. It is therefore important to gauge their absolute and relative concentrations in soils that are used for crop production. In this study the arsenic and heavy metal concentrations in 274 mineral soil samples and 38 organogenic soil samples taken from South Savo province in 2000 were determined using the aqua regia extraction technique. The soil samples were collected from 23 farms.The elements analyzed were arsenic, cadmium, chromium, copper, mercury, nickel, lead and zinc. The median...

Drivkræfter bag landmænds til- og fravalg af økologisk drift
Provedor de dados: 21
Autores: Risgaard, Marie-Louise; Kaltoft, Pernille; Frederiksen, Pia.
I en lang årrække var økologisk jordbrug i Danmark i vækst, og det var nærmest utænkeligt at en større tilbagelægning kunne finde sted – der var end ikke et ord for et sådant fænomen. Imidlertid tyder analyser af avlerlisterne på, at den tilgang der var i antallet af økologer i 1990’erne dækkede over et større antal omlæggere kombineret med et antal bedrifter, der ophørte med økologisk drift. På baggrund af den nuværende situation med nogenlunde ligeligt fordelt tilgang, udvidelse og ophør med økologisk drift – i et arealmæssigt perspektiv – kan der kun gisnes om, hvor det økologiske jordbrug bevæger sig hen i de kommende år.

Changes in farm structure following conversion to organic farming in Denmark
Provedor de dados: 21
Autores: Langer, Vibeke.
Compared with conventional farms, organic farms are expected to be more diverse, less specialized and less intensive, and organic farms as a group are expected to contribute to a more uniform regional distribution of farm types. Data on farm size, crop distribution and livestock intensity prior to conversion and planned after conversion on 448 Danish farms, which began conversion to organic farming in 1997, are presented in adressing two questions: 1) what features characterize Danish farms that convert from conventional to organic farming ?, 2) what do the  farms convert to: do farm types, stocking rates and crop distribution change with conversion ? In 1997, dairy farms dominated among the converting farms in acreage, and a large majority (80-97%) of the...

This review addresses the need for review of this burgeoning literature by summarizing opinions of previous reviews and trends in recent studies on the impacts of climate change on plant health. Sudden Oak Death is used as an introductory case study: Californian forests could become even more susceptible to this emerging plant disease, if spring precipitations will be accompanied by warmer temperatures, although climate shifts may also affect the current synchronicity between host cambium activity and pathogen colonization rate. A summary of observed and predicted climate changes, as well as of direct effects of climate...

The cocoa swollen shoot virus disease is a major factor limiting cocoa (Theobroma cacao L.) productivity for West African farmers. The only treatment against this disease is to cut infected trees and replant with disease-free planting material. Research has recommended the prevention measures: (i) cordon sanitaire (leaving 10-m-wide cocoa-free zone around cocoa), (ii) barrier cropping, (iii) using partly tolerant hybrids, and (iv) removing specific alternative host tree species. Here, we evaluate the current adoption of these measures and identify their adoption constraints. We conducted a quantitative survey with 396 farmers in the Eastern and Western Regions of Ghana, held six focus group discussions and hosted a multi-stakeholder validation workshop...

Autores: Martin, . Jörg.
Beef cattle farmers (single suckling or feeder cattle) must spend special attention to aspects of breeding, management and selling to guarantee a marketable ecological beef production.  These criterions are decisive:  1. The guarantee of excellent quality of forage is the base of ecological beef production.  2. The single suckling must be adapted on habitat to produce store cattle by using combined pure-breeding and cross-breeding programmes.  3. The beef production must be adapted on forage situation of the farms to use the advantages of bulls, bullocks and heifers in production of quality beef.

Training dairy bull calves to stay within light-built electric fences
Provedor de dados: 21
Autores: Martiskainen, Paula; Tuomisto, Leena; Huuskonen, Arto; Mononen, Jaakko.
Training cattle to avoid electric fences before turnout to grazing reduces the risk of the animals breaking out from their paddock. We investigated the time needed for dairy bull calves to learn to avoid a light-built electric fence. Nineteen dairy bull calves were trained to an electric fence in a training yard during seven days. The number of electric shocks the animals received from the training fence was recorded continuously. After the training period, the calves were turned to pasture. Nine of the animals were also grazed the following summer as yearlings, and observed before turnout in a smaller enclosure. The calves got more shocks from the fence during training hour 1 than during any of the following seven hours. The number of shocks the calves...

Differences in Yield Parameters of Emmer in Comparison with Old and New Varieties of Bread Wheat
Provedor de dados: 21
Autores: Konvalina, Petr; Capouchova, Ivana; Stehno, Zdenek; Moudry, Jan.
Emmer wheat (Triticum diccocum Schrank) belonged to the most frequent species of cereals in the past. Nowadays, it is grown in arid and montane areas in particular. Interest in this cereal species has increased, as it is tolerant to biotic and abiotic stressing factors. Therefore, yield parameters were evaluated in three-year (2007, 2008 and 2010) trials that were carried out in two different localities in the Czech Republic. Results of the research were compared to characteristics of four old and two top  modern bread wheat (Triticum aestivum L.) cultivars. The emmer wheat varieties were resistant to usual wheat diseases. They formed their yield by a quantity of productive tillers (2.5), whereas the varieties of bread wheat had less productive tillers...

Autores: Bludau, Maren Jana; Maeschli, Ariane; Leiber, Florian; Steiner, Adrian; Klocke, Peter.
Poor udder health represents a serious problem in dairy production and has been investigated intensively, but heifers generally have not been the main focus of Mastitis control. The aim of this study was to evaluate the prevalence, risk factors and consequences of heifer mastitis in Switzerland. The study included 166,518 heifers of different breeds (Swiss Red Pied, Swiss Brown Cattle and Holstein). Monthly somatic cell counts (SCCs) provided by the main dairy breeding organisations in Switzerland were monitored for 3 years; the prevalence of subclinical mastitis (SCM) was determined on the basis of SCCs ≥100,000 cells/mL at the first test date. The probability of having SCM at the first test date during lactation was modelled using logistic regression....

Zwiebelproduktion über Steckzwiebeln: Die Qualität des Pflanzguts entscheidet für den Ertrag
Provedor de dados: 21
Autores: Koller, Martin.
Im Bioanbau hat der Anbau von Zwiebeln über Steckzwiebel immer noch eine grosse Bedeutung. Zwar eignet sich die Kulturweise gut für den Bioanbau, da die Unkrautbekämpfung im Vergleich zu anderen Zwiebelanbausystemen einfach ist, aber die Schalenfestigkeit und die Lagerfähigkeit der Zwiebeln aus der gesteckten Kultur ist oft mangelhaft. Ziel der durchgeführten Versuche war, neue und bekannte Sorten auf diese Eigenschaften zu prüfen.  Das FiBL hat in Zusammenarbeit mit Bioproduzenten im Jahr 2005 an zwei Standorten Versuche durchgeführt. Getestet wurden Standardsorten sowie Jetset aus zwei Herkünften, eine neue Sorte und zwei Säzwiebelsorten, die im Vorjahr als Steckzwiebeln produziert wurden.

Soil quality aspects of humid sandy loams as influenced by organic and conventional long-term management
Provedor de dados: 21
Autores: Schjønning, Per; Elmholt, Susanne; Munkholm, Lars J.; Debosz, Kasia.
The development of low-input farming systems requires knowledge of the extent to which management characteristics influence the soil as a habitat for micro-organisms and a medium for plant growth. This paper presents a study of long-term effects of organically and conventionally cultivated systems on a range of soil physical, chemical and biological characteristics in Denmark. Seven soils were included, falling into three groups (I¯III). Each group consists of an organically managed soil (Org) referenced by one or two conventionally managed soils (Conv) with the same soil type (sandy loam) and pedological history. All organically managed soils were dairy farm soils (H), which had been organically managed for 46, 47 and 40 years, respectively. They had...

Global Justice and the Shift in Property Rights for Plant Genetic Resources
Provedor de dados: 21
Autores: de Goede, Ludo M.
Although new technologies in plant breeding have the potential to reduce poverty and improve global food security, a shift in property regime for plant genetic resources (PGRs) prevents this potential from being realised. As the emergence of biotechnology has increased the value of PGRs, rents-seeking behaviour by the plant breeding industry spurred the emergence of intellectual property rights (IPRs) for improved plant varieties. Whereas this system is globally implemented through the TRIPS agreement, biodiversity-rich developing countries increasingly use the Convention on Biological Diversity (CBD) to protect their PGRs through state sovereignty. By using an economic perspective, this article aims to explain the appropriation of PGRs and the efficiency...

Autores: Isense, A.; Leiber, F.; Bieber, A.; Spengler, A.; Ivemeyer, S.; Maurer, V.; Klocke, Peter.
Body condition scoring is a common tool to assess the subcutaneous fat reserves of dairy cows. Because of its subjectivity, which causes limits in repeatability, it is often discussed controversially. Aim of the current study was to evaluate the impact of considering the cows overall appearance on the scoring process and on the validity of the results. Therefore, two different methods to reveal body condition scores (BCS), ‘independent BCS’ (iBCS) and ‘dependent BCS’ (dBCS), were used to assess 1111 Swiss Brown Cattle. The iBCS and the dBCS systems were both working with the same flowchart with a decision tree structure for visual and palpatory assessment using a scale from 2 to 5 with increment units of 0.25. The iBCS was created strictly complying with...

The nitrogen supply plays an important role in achieving quality characteristics in organic potato farming. Different defoliation systems of ryegrass–clover may influence the amount of fixed nitrogen available to the tubers. In a field experiment, the effect of different defoliation systems (cutting, mulching and a combination of them) of the pre-crop ryegrass–clover on selected quality attributes of organically grown potatoes, destined for processing into French fries (cv. Agria) or crisps (cv. Marlen), were conducted in two consecutive years (2003 and 2004).  Parameters studied included compounds related to the sensory properties of potato food (tuber dry matter, starch, reducing sugars) as well as nutritional quality (nitrogen,minerals). Selected...

O segmento da agricultura familiar apresenta características específicas na sua organização, como a utilização de mão-de-obra familiar, menor dimensão territorial da unidade produtiva e a lógica ou racionalidade camponesa está voltada em atender as demandas da própria família e não, de imediato, as necessidades do mercado. Estes são alguns dos traços que permitiram sua reprodução ao longo do processo de desenvolvimento capitalista. Por outro lado, estas características representam a possibilidade de transição de um modelo de agricultura convencional, pautado no excessivo uso dos recursos naturais não-renováveis, para um sistema de produção agroecológico, que tem como base os pilares da sustentabilidade (ecológica, econômica, social, cultural,...

Two groups of five adult lactating East Friesian milk sheep and Saanen dairy goats were kept on pastures at 2000 to 2600 m a.s.l. (SA: sheep alpine; GA: goats alpine) and 400 m a.s.l. (SL: sheep lowland; GL: goats lowland). The animals were milked twice daily and the milk yield was measured. Blood, milk, skin and forage samples were collected and the left metatarsi were measured with peripheral quantitative computed tomography. The relative humidity and air temperature were recorded and the ultraviolet B (UVB) radiation was measured with a solar meter at both research stations. In addition, animals from the alpine group were equipped with a...

Autores: Gössinger, Katharina; Freyer, Bernhard.
Corporate Social Responsibility (CSR) gewann in den letzten Jahren in Mitteleuropa enorm an Bedeutung und wird heute bereits von zahlreichen österreichischen Unternehmen in ihre Firmenstrategie miteinbezogen. Doch was steckt hinter dem Konzept, das seinen Ausgang im angloamerikanischen Raum nahm? Ist CSR ein bloßer Marketinggag, oder gelebte Verantwortung? Wie werden CSR-ähnliche Leistungen der Landwirtschaft in der Gesellschaft wahrgenommen? Welche Rolle spielt CSR in der österreichischen Lebensmittelbranche? Welche Bedeutung haben CSR und ähnliche Ansätze im Biobereich?

Clover species in grass-clover silages affects milk fatty acid composition
Provedor de dados: 21
Autores: Steinshamn, Håvard; Thuen, Erling; Brenøe, Ulrik Tutein.
The objective of this study was to examine the effect of clover species on milk fatty acid  (FA) composition. Lactating dairy cows were allocated to two groups and fed grass-clover silage containing either white clover (WC) or red clover (RC), without or with concentrate supplementation. No significant interaction of clover species with concentrate supplementation could be observed. RC milk had significantly higher proportion of polyunsaturated FAs (P&lt;0.001), particularly C18:3n-3 (P&lt;0.001), and contained a higher n-3/n-6 FA ratio (P&lt;0.05) than WC milk. It is concluded that RC silage, independent of concentrate supply, yielded milk with more beneficial FA composition than WC silage.

Autores: Zander, Katrin.
Bedingt durch die aktuelle politische Situation wie auch durch die rückläufigen Preise für konventionelle Gartenbauprodukte sehen sich viele Betriebsleiter veranlasst, über eine Umstellung auf ökologische Erzeugung nachzudenken. Der ökologische Anbau ist europaweit über die VO (EWG) 2092/91 geregelt. Die Einhaltung der Richtlinien dieser VO wird in Deutschland von privaten Kontrollstellen, die unter staatlicher Aufsicht stehen, überwacht. Gerade im Bereich der Sonderkulturen wird die Bedeutung der Richtlinien der nationalen Anbauverbände deutlich, die wesentlich besser als die EU-VO den speziellen Gegebenheiten der gartenbaulichen Produktion Rechnung tragen können.    Die Umstellung auf ökologischen Anbau ist durch die ganzheitliche Sichtweise in der...

Wildlife friendly agriculture: which factors do really  matter? A genetic study on the field vole (Microtus agrestis)
Provedor de dados: 21
Autores: Marchi, Chiara; Andersen, Liselotte Wesley; Damgaard, Christian F.; Olsen, Kent; Jensen Secher, Thomas; Loeschcke, Volker.
The impact of landscape structure and land management on the dispersal of populations of wild species inhabiting the agricultural landscape was investigated by determining the genetic diversity and gene flow of field vole (Microtus agrestis) in three different areas. The main hypotheses were: I) organic farms act as genetic sources and diversity reservoirs for species living in agricultural areas and II) gene flow and genetic structure in the agricultural landscape are influenced by the degree of landscape complexity and connectivity. A total of 443 individuals were sampled within two consecutive years from two agricultural areas and one relatively undisturbed grassland area. Fifteen polymorphic microsatellite loci and the central part of the cytochrome-b...

Self identified research needs of New York organic farmers
Provedor de dados: 21
Autores: Baker, Brian P.; Smith, Douglas B.
A survey of organic farmers in New York State identified problems in need of university research. Weed management was the most frequently mentioned problem by far, identified as significant by two-thirds of the organic farmers. Only a few other problems were listed as significant, including insufficient time for farm work, lack of markets, low prices, and lack of appropriate tools. These were cited by more than a third of the farmers. Drought, insect management, and a lack of a dependable supply of labor were cited by about one-third of the respondents. The survey also examined organic farmers' information sources. They do not use conventional sources of agricultural information, such as the extension service and conventional agricultural media, as much as...

Autores: Soinne, Helena; Peltovuori, Tommi.
The potential effects of freezing on phosphorus (P) chemistry in Finnish soils are not well known. We studied the effects of multiple freeze-thaw cycles on soil P chemistry in a laboratory incubation experiment with one organic and one mineral surface soil. The soils were incubated at +5°C or at alternating +5/–20°C temperatures for 24 weeks, either without amendment or amended with pig slurry or with commercial compound fertilizer (NPK 20–3–9). After incubation, the soils were analyzed for water-soluble reactive and unreactive P, and acid ammonium acetate soluble P (PAAA). Freezing and thawing of soils during the incubation had no significant effect on any of the water-soluble P fractions or PAAA. The outcome was most likely a consequence of the good P...

A rainfall simulation study on the relationships between soil test P versus dissolved and potentially bioavailable particulate phosphorus forms in runoff
Provedor de dados: 21
Autores: Uusitalo, Risto; Aura, Erkki.
Runoff from clayey soils often contains abundant particulate phoshorus (PP), part of which may solubilize in surface waters. Monitoring losses of potentially bioavailable forms of PP is expensive, calling for other ways to predict them. Such predictions could be based on soil loss and available soil P indices, e.g., agronomic P status. To study correlations between P pools in runoff versus soil P saturation (by Mehlich 3 extraction; DPSM3) and acetate soil test P (PAc), 15 clayey soils of south Finland were subjected to laboratory rainfall simulation. Runoff from these simulations was analyzed for concentrations of suspended soil (TSS), dissolved molybdate-reactive P (DRP), total P (TP), and, as normalized to soil loss, potentially bioavailable forms of...

Tracing the Pathways from Research to Innovation: Evidence from Case Studie
Provedor de dados: 21
Autores: Barjolle, Dominique; Midmore, Peter; Schmid, Otto.
The complex process through which agricultural research stimulates innovation and achieves policy goals has commonly been treated as a ‘black box’ in the scientific literature. Statistical correlations between measured expenditure and impacts, where satisfactorily established, have mostly led to details of the research and innovation system being ignored. However, identifying and exploring causal chains of impact propagation can strengthen agricultural innovation. IMPRESA investigated impact mechanisms for research‐based innovations in six case studies using a Participatory Impact Pathway Assessment approach. Several suggestions result for improving performance and public support for agricultural research. Planning for impact is needed at the design phase...

Manipulating cover crop growth by adjusting sowing time and cereal interrow spacing to enhance residual nitrogen effects
Provedor de dados: 21
Autores: De Notaris, Chiara; Rasmussen, Jim; Sørensen, Peter; Melander, Bo; Olesen, Jørgen E.
Legume-based cover crop (CC) mixtures can increase nitrogen (N) availability in arable systems, reducing the need for external N inputs, as they retain soil N and fix atmospheric N2. However, they need sufficient biomass accumulation to influence soil N availability. Early establishment through undersowing can improve CC growth and plant N accumulation, but competition with the main crop should be minimized. This study aimed to investigate the effect of main crop inter-row spacing (12, 18, 24 cm), manure application (without, with) and CC undersowing (early, late, no cover crop) on N accumulation in a legume-based CC mixture and the residual N effect on the following crop. We conducted a field experiment in Denmark with spring wheat as main crop and spring...

Impact of long-term conventional and organic farming on the diversity of arbuscular mycorrhizal fungi
Provedor de dados: 21
Autores: Oehl, F.; Sieverding, E.; Mäder, Paul; Dubois, D.; Ineichen, K.; Boller, T.; Wiemken, A.
Previous work has shown considerably enhanced soil fertility in agroecosystems managed by organic farming compared to conventional farming. Arbuscular mycorrhizal fungi (AMF) play a crucial role in nutrient acquisition and soil fertility. The objective of this study was to investigate the diversity of AMF in the context of a long-term study in which replicated field plots, at a single site in Central Europe (DOK-Trial. Therwil, Switzerland), had been cultivated for 22 years according to two "organic" and two "conventional" farming systems. In the 23rd year, the field plots, carrying an 18-month-old grass-clover stand, were examined in two ways with respect to AMF diversity. Firstly, AMF spores were isolated and morphologically identified from soil samples....

Evaluation of wildlife management through organic farming
Provedor de dados: 21
Autores: Topping, C.J.
Organic farming has often been suggested as a way of  increasing biodiversity in agricultural landscapes, but literature reports a variable success. The drivers in play are multi-factorial and include the particular species groups under consideration, the precise form of organic management, the landscape structural and management context, the area and scale considered, and the historical context. Here ALMaSS, a comprehensive agent-based model simulation system, was used to produce an assessment of the impact of organic and conventional farm types, landscape structure, and management context for six common agricultural wildlife species. ALMaSS outputs can be expressed as a simple index of relative change in abundance and distribution, allowing easy...

Authentication of organically grown plants – advantages and limitations of atomic spectroscopy for multi-element and stable isotope analysis
Provedor de dados: 21
Autores: Laursen, K.H.; Schjoerring, J.K; Kelly, S.D.; Husted, S.
Organic food products are believed to be healthier, safer and more environment-friendly than their conventional counterparts and are sold at premium prices. Consequently, adulteration of organic plants and fraudulent activities for economic profit are increasing. This has spurred the development of sophisticated analytical procedures for testing authenticity. We review the use of multi-element and stable-isotope analysis based on atomic spectroscopy for discriminating between organic and conventional plants. We conclude that inductively-coupled plasma-mass spectrometry, stable-isotope analysis of bulk plant tissue, and compound-specific isotope analysis based on isotope ratio-mass spectrometry are promising tools for documenting the fertilization history...

Autores: Steinshamn, Håvard; Höglind, Mats; Havrevoll, Øystein; Saarem, Kristin; Lombnæs, Inger Helene; Steinheim, Geir; Svendsen, Asgeir.
The purpose of this study was to compare the effect of grazing on mountain (M) versus cultivated lowland pasture (C) on the performance and meat quality of suckling calves (Experiment 1 and 2). In addition, the effect of finishing on C after M on growth and meat quality was assessed (Experiment 2). Animals on C and M had on average similar live weight gain and carcass weight in the first experiment. However, the performance depended on year as gain and carcass weight was higher on C than on M in the first year and vice versa in the second year. In the second experiment the calves on M had lower gain and carcass weight than on C. Three week finishing on C after M compensated to some extent for the lower growth rate on M. Overall, the results indicate that...

Autores: Bellostas, Natalia; Hauggaard-Nielsen, Henrik; Andersen, Mette Klindt; Jensen, Erik Steen.
Intercropping, the practical application of ecological principles such as diversity, interference, competition and coexistence in agriculture, is gaining increasing interest in organic farming. To be able to improve the management of intercrops, a more detailed knowledge is required on aspects of interference between crops. A bioassay and a pot experiment were conducted to assess both the mechanisms and the time of expression of processes involved in the early interference between pea (Pisum sativum L.), barley (Hordeum vulgare L.) and oilseed rape (Brassica napus L.) when grown as intercrops. Conditions of non-limiting nutrient and water supply were chosen to eliminate competition for these growth factors. The bioassay gave no indication of competitive...

To develop a practical methodology for the authentication of organic salmonid products, 130 fillet samples of trout and salmon originating from organic and conventional aquaculture as well as wild stocks (salmon) were collected from the German market over one year. Combined stable isotope analysis of d15N and d13C in defatted dry matter allowed differentiation of organically farmed from conventionally farmed salmon and brown trout, whether raw, smoked or graved. For the additional distinction of organic and wild salmon, a second analysis of d13C in fish lipids was required. Fatty acid analysis completely differentiated the three production types of salmon just by the linoleic acid content in the fish lipids, which was lowest in wild and highest in...

Understanding the development of organic agriculture in Flanders(Belgium): A discourse analytical approach
Provedor de dados: 21
Autores: De Cock, Lieve; Dessein, Joost; de Krom, Michiel P.
Despite a fast-growing national consumer market for organic products and active governmental support for organic agriculture, organic production in Flanders has shown little growth since the late 1990s. Our discourse analytical approach offers important insights into the causes of the limited organic pro-duction capacity in Flanders complementary to more common political-institutional or actor-oriented perspectives. Our analysis reveals that for decades, a competition between two mutually exclusive organicfarming discourses has hindered a collaborative effort to contribute to a growth of the organic agricultural sector by conventional and organic agricultural communities, agricultural policy makers, and food market actors. Such collaboration however,...

Autores: Gravador, Rufielyn S.; Luciano, Guiseppe; Jongberg, Sisse; Bognanno, Matteo; Scerra, Manuel; Andersen, Mogens L.; Lund, Marianne N.; Priolo, Alessandro.
Male Comisana lambs were individually stalled and, for 56 days, were fed concentrates with 60% barley (n = 8 lambs), or concentrates in which barley was partially replaced by 24% or 35% carob pulp (n = 9 lambs in each group). The intramuscular fatty acids were analyzed and the color stability, lipid and protein oxidation were measured in fresh meat overwrapped with polyvinyl chloride film at 0, 3 or 6 days of storage at 4 °C in the dark. Carob pulp increased the concentration of polyunsaturated fatty acids (PUFA) in muscle, including the rumenic acid (P &lt; 0.01), and reduced the saturated fatty acids (P &lt; 0.01) and the n-6/n-3 PUFA ratio (P = 0.01).

Autores: Ellingsen, Kristian; Mejdell, Cecilie M.; Hansen, Berit.
En Internett-basert spørreundersøkelse (QuestBack™) ble sendt ut til 400 norske stordyrpraktikere i januar 2008. Totalt svarte 207 (52 %) veterinærer; 114 (55 %) av disse oppfylte inklusjonskriteriene. I undersøkelsen ble deltakerne spurt om kjennskap til Debios regelverk og ulike parametere relatert til kalvehelse og -velferd i økologiske besetninger. De ble også spurt om hva de betraktet som det største velferdsfortrinnet og det største kritiske punktet relatert til kalvevelferd i økologiske besetninger. Respondentene ble delt i to grupper basert på erfaring fra få (F, n = 70) og mange (M, n = 44) økologiske bruk.   Til tross for at M-gruppen hadde signifikant bedre kjennskap til Debio-reglene enn F-gruppen, vurderte de sitt kunnskapsnivå som...

Magen-Darm Parasiten – Unterscheiden sich Schweizer Schafrassen bezüglich ihrer Anfälligkeit?
Provedor de dados: 21
Autores: Heckendorn, Felix.
Magen-Darm Würmer sind eines der grössten Probleme in der Haltung von kleinen Wiederkäuern. Infektionen mit diesen Parasiten führen je nach Befallsgrad zu erheblichen Einbussen in der Leistung der Tiere und können deren Gesundheit stark beeinträchtigen. Die Kontrolle von Magen-Darm Würmern stützt sich seit über 30 Jahren auf den Einsatz von Entwurmungsmitteln. Der lang jährige Einsatz dieser Mittel ist aber nicht unproblematisch. Bereits vor 15 Jahren gab es erste Berichte über reduzierte Wirksamkeiten von gewissen Entwurmungsmitteln. Weiterführende Studien brachten den Beweis, dass gewisse Wurmpopulationen Resistenzen gegen die Mittel entwickelt hatten. Gegenwärtig sind resistente Magen-Darm Wurmpopulationen weltweit eher die Regel als die Ausnahme und...

Autores: Gamba, Ursula.
La biodiversità è un indicatore della salute dell'ambiente ed è la principale risorsa naturale a subire gli imprevedibili cambiamenti climatici. Molta biodiversità è stata persa: questo aspetto è meglio conoscito come erosione genetica. La riduzione della biodiversità è determinata sia dall'attività umana che dai naturali processi evolutivi.  Istituti di ricerca, governi regionali e associazioni non governative lavorano a diversi livelli per preservare molte specie in via d'estinzione. Ci sono molte associazioni di agricoltori custodi (seed savers) nel mondo che stanno ricercando e conservando cultivars locali di piante.

Autores: Bongiorno, Giulia; Bünemann, Else K.; Oguejiofor, Chidinma U.; Meier, Jennifer; Gort, Gerrit; Comans, Rob; Mäder, Paul; Brussaard, Lijbert; de Goede, Ron.
Soil quality is defined as the capacity of the soil to perform multiple functions, and can be assessed by measuring soil chemical, physical and biological parameters. Among soil parameters, labile organic carbon is considered to have a primary role in many soil functions related to productivity and environmental resilience. Our study aimed at assessing the suitability of different labile carbon fractions, namely dissolved organic carbon (DOC), hydrophilic DOC (Hy-DOC), permanganate oxidizable carbon (POXC, also referred to as Active Carbon), hot water extractable carbon (HWEC) and particulate organic matter carbon (POMC) as soil quality indicators in agricultural systems. To do so, we tested their sensitivity to two agricultural management factors (tillage...

Det glædelige er at selv ret unge økologiske hegn og relativt nyomlagte bedrifter tilsyneladende også har stor betydning for agerlandets natur. En mere varieret hegnsvegetation giver flere levemuligheder også for andre arter, både insekter og højere dyr. Med omtanke kan landmanden altså påvirke og beskytte naturen i skel og hegn via sin daglige drift og dermed bidrage til at forbedre naturen i agerlandskabet.

A long-term field experiment demonstrates the influence of tillage on the bacterial potential to produce soil structure-stabilizing agents such as exopolysaccharides and lipopolysaccharides
Provedor de dados: 21
Autores: Cania, Barbara; Vestergaard, Gisle; Krauss, Maike; Fliessbach, Andreas; Schloter, Michael; Schulz, Stefanie.
Background: Stable soil aggregates are essential for optimal crop growth and preventing soil erosion. However, tillage  is often used in agriculture to loosen the soil, which disrupts the integrity of these aggregates. Soil aggregation can be  enhanced by bacteria through their ability to produce exopolysaccharides and lipopolysaccharides. These compounds  stabilize soil aggregates by “gluing” soil particles together. However, it has yet to be shown how tillage influences the  bacterial potential to produce aggregate-stabilizing agents. Therefore, we sampled conventional and reduced tillage treatments at 0–10 cm, 10–20 cm and 20–50 cm from a long-term field trial in Frick, Switzerland. We compared the stable aggregate fraction of the soil and the bacterial...

Automated intelligent rotor tine cultivation and punch planting to improve the selectivity of mechanical intra-row weed control
Provedor de dados: 21
Autores: Rasmussen, Jesper; Griepentrog, Hans W.; Nielsen, J.; Henriksen, Christian Bugge.
There is much emphasis on technical aspects related to sensor or mapping techniques, which enable so-called intelligent cultivators to target the intra-row spaces within crop rows. This study investigates (i) an expected advantage of an intelligent rotor tine cultivator (the cycloid hoe) in terms of crop-weed selectivity and (ii) an expected synergistic effect between  punch planting and post-emergence weed harrowing in terms of improved crop-weed selectivity. Selectivity is defined as the relationship between weed control and associated crop density decline one week after cultivation, and punch planting is a sowing technique where holes are created in the ground with a minimum of soil disturbance and seeds are inserted into them, without soil disturbance...

How can we approach strategies and innovations specific to organic farmers? Is the appearance of new practices evidence of a modification of the structure of professional organic farming? On the basis of a field study carried out in the Midi-Pyrénées region in France, sociological analysis casts light on several examples of strategies and innovations specific to the world of organic farming and from which they arise. The strategic courses of action taken by organic farmers are therefore analysed in relation to organic farming characteristics, defined as the set of issues, interests, representations and other specific characteristics that structure this socio-professional field.

Cacao agroforestry systems have higher return on labor compared to full-sun monocultures
Provedor de dados: 21
Autores: Armengot, Laura; Barbieri, Pietro; Andres, Christian; Milz, Joachim; Schneider, Monika.
The global demand for cacao has recently increased. To meet this demand, the cultivated area has been expanded in tropical forest areas and production has intensified by replacing traditional agroforestry systems with monocultures. This has led to a loss of biodiversity in cacao-growing areas. More sustainable production systems such as agroforestry and organic managed systems are expected to yield less cacao, but by-crops and premium prices, respectively, might economically compensate for the lower yields. Here, we compared the productivity and the return on labor, that is the return per working day, of four different cacao production systems: agroforestry and monocultures under organic and conventional management. Cacao and by-crop yields, costs,...

Emissions of nitrous oxide from arable organic and conventional cropping systems on two soil types
Provedor de dados: 21
Autores: Chirinda, N.; Carter, M.S; Albert, K.R.; Ambus, P.; Olesen, J.E.; Porter, J.R.; Petersen, S.O.
Conventional cropping systems rely on targeted short-term fertility management, whereas organic systems depend, in part, on long-term increase in soil fertility as determined by crop rotation and management. Such differences influence soil nitrogen (N) cycling and availability through the year. The main objective of this study was to compare nitrous oxide (N2O) emissions from soil under winter wheat (Triticum aestivum L.) within three organic and one conventional cropping system that differed in type of fertilizer, presence of catch crops and proportion of N2-fixing crops. The study was replicated in two identical long-term crop rotation experiments on sandy loam soils under different climatic conditions in Denmark (Flakkebjerg–eastern Denmark and...

Autores: Sundrum, Albert; Rubelowsky, Ina.
To prove the meaningfulness of design criteria in relation to claw disorder and mortality of fattening bulls a cohort analysis was carried out on 50 farms with housing systems characterised by fully slatted floor, deep litter or litter+concrete floor. Hoofs of the bulls were collected after slaughtering and examined for pathological findings. Space allowance, feeding space, pen depth and quality of the floor were integrated into a TGI-40 protocol and related to the incidence of early losses.   Slatted floor pens were characterised by a low space allowance and a low pen depth. In contrast, dimensions of pens with deep litter and litter+concrete floor were clearly larger but showed a wide and overlapping variation in the different design criteria. Hoofs on...

Provedor de dados: 21
Autores: Vogl, Christian R.; Kilcher, Lukas; Schmidt, Hanspeter.
Organic farming is a promising agricultural method with positive effects on the human ecological and social environment. Governments have taken over a major role in defining organic farming by creating legal standards. Many countries all over the world have established a certification and accreditation system in order to protect the justified expectations of consumers with regard to processing and controlling the product quality of organic goods and to protecting producers from fraudulent trade practices. As they are relevant to international trade, these standards do not only influence the organic farming movement on the national level but also have a converse impact across national borders. Organic farming was established in a bottom-up process as...

Is it possible to improve the yield and grain protein concentration of organically-farmed wheat using cover crops or intercrops?
Provedor de dados: 21
Autores: JUSTES, J.; BEDOUSSAC, L.; PRIEUR, L.
The objective of our work was to investigate innovative sustainable cropping systems to produce regular yields of wheat with a satisfactory grain protein concentration in organic farming systems. Achieving good production levels in stockless French organic farming systems is a major challenge due to strong N limitation. Our approach is mainly based on a better valorisation of the natural nitrogen resources from soil mineralisation and symbiotic fixation of legumes, and not by an increase in the use of organic fertiliser. Two experiments were carried out in southwestern France where winter wheat and durum wheat were grown for their use in human consumption (bread and pasta, respectively). On one hand, cover crops were sown in summer and were incorporated in...

Wenn Sauen zusammen säugen
Provedor de dados: 21
Autores: Früh, Barbara.
Die Gruppenhaltung von Sauen mit ihren Ferkeln, das heisst das Umstallen von Sauen und Ferkeln im Alter zwischen zwei und drei Wochen von der Abferkelbucht in einen Gruppensäugestall, ist nichts Neues, kehrt aber auf Biohöfen immer mehr in die Praxis zurück. In einem Projekt wurde diese Haltungsform auf 31 Biobetrieben in Deutschland,Österreich und der Schweiz unter die Lupe genommen. Fazit: Diese Methode bringt verschiedene Vorteile (z.B. geringere Stallbaukosten, geringerer täglicher Arbeitsaufwand, artgerechte Tierhaltung) und kann empfohlen werden.

Risiken und Chancen für Europas Bio-Landbau
Provedor de dados: 21
Autores: Sanders, Jürn.
Der Abbau von Handelshemmnissen hat einen bedeutenden Einfluss auf die agrarpolitischen Rahmenbedingen, denen der Bio-Landbau ausgesetzt ist. Es ist absehbar, dass die zukünftigen Rahmenbedingungen zu einem intensiveren Wettbewerb im Bio-Sektor führen werden und es folglich mehr an den Konsumenten und Konsumentinnen liegt, ob sie durch den Kauf regionaler bzw. europäischer Bio-Produkte den Bio-Landbau in der EU unterstützen. Für die Wirtschaftlichkeit des Bio-Landbaus in Europa ist es besonders wichtig, dass das Budgetvolumen der Green-Box-Maßnahmen nicht beschränkt oder reduziert wird. Sollte sich die Höhe der Direktzahlungen verstärkt nach der erbrachten Umweltleistung richten, würden Bio-Betriebe von dieser Änderung besonders profitieren.

Climatic potential and risks for apple growing by 2040
Provedor de dados: 21
Autores: Kaukoranta, Timo; Tahvonen, Risto; Ylämäki, Arto.
The impact of climatic change in 1971–2040 on the potential production areas and risks to nine apple cultivars (Malus domestica Borkh.) was studied over continental Finland using agro-climatic indices and gridded daily mean (Tm) and minimum temperatures from the Rossby Centre regional atmospheric climate model (RCA3) with SRES A2. Point data on daily minimum temperatures from 14 weather stations and low and high warming scenarios were also used. From the 1970’s to the present day, the areas of successful maturing of fruits have strongly expanded northwards. It is predicted that in 2011–2040, the warming of climate will allow expansion of commercial production in the south-eastern lake area, and a wider selection of cultivars for home gardens up to...

The Glass House: Crucible of Biodynamic Agriculture
Provedor de dados: 21
Autores: Paull, John.
The Glass House (1914) at Dornach, Switzerland, in the precinct of the Goetheanum, is the oldest extant building designed by Rudolf Steiner. The building is intimately associated with the development of biodynamic agriculture. It was in the Glass House that Assya Turgeniev produced the remarkable engraved coloured glass windows of both the first and the present Goetheanum building, and hence the name 'Glass House'. In 1919, with Steiner's approval, Ehrenfried Pfeiffer (1899-1961) and Guenther Wachsmuth (1893-1963) set up a research laboratory in the basement of the Glass House. Thus began two decades of research work by Pfeiffer at Dornach, which culminated in the publication of his book 'Bio-Dynamic Farming and Gardening' (1938) in five languages, Dutch,...

Monitoring recovery after clinical mastitis in dairy cows after 2 different types of treatment
Provedor de dados: 21
Autores: Fossing, C.; Vaarst, M.; Ersbøll, A.K.; Thamsborg, S.
A prospective observational study, split over two periods, was set up to describe initial symptom patterns and convalescence progression of treated clinical cases of mastitis on 29 Danish dairy farms. In the first study period all cows were treated with antibiotics (group A); in the second study period cows were treated with classical homeopathy (group B1) or antibiotics (group B2). Initial symptom and treatment patterns were examined by factor analyses. The 1st analysis included all clinical observations made on treatment day. The difference between the 3 groups in mean scores for revealed factors was tested by Students t-test. The 2nd and 3rd analyses were performed separately for groups A and B1 and included all variables measured. Differences between...

Effect of intercropping normal-leafed or semi-leafless winter peas and triticale after shallow and deep ploughing on agronomic performance, grain quality and succeeding winter wheat yield
Provedor de dados: 21
Autores: Gronle, Annkathrin; Heß, Jürgen; Böhm, Herwart.
Winter peas (Pisum sativum L.) are a promising alternative to spring peas in organic farming. Intercroppingwinter peas and cereals may be a beneficial way to improve lodging resistance in normal-leafed andweed suppression in semi-leafless winter peas. At the same time, there is an increasing interest in areduction in tillage intensity, e.g. shallow ploughing. A normal-leafed, coloured-flowered (cv. E.F.B. 33)and a semi-leafless, white-flowered winter pea (cv. James) were cultivated as sole crops or in intercropswith triticale (Triticosecale Wittmarck) on a loam soil under Northern German conditions during twoseasons (2009/2010, 2010/2011) and compared for winter survival, lodging resistance, yield performance,grain quality and succeeding winter wheat...

Autores: Reisinger, Edgar; Pusch, Jürgen; van Elsen, Thomas.
Der Anbau von Feldfrüchten wird durch Pflanzen beeinträchtigt, die ohne bewusstes Zutun des Menschen auftreten und zu einer Minderung der Erträge führen können. Derartige Kräuter und Gräser werden allgemein als Unkräuter bezeichnet. Die Definition der Unkräuter als unerwünschte und Schaden verursachende Pflanzen erweist sich als einseitig wirtschaftsorientiert. Unter ökologischen Aspekten handelt es sich um Pflanzen, die zusammen mit den Nutzpflanzen auftreten und in ihrer Lebensweise und ihren Standortansprüchen den Kulturpflanzen angepasst sind.

Soil mechanical behaviour of sandy loams in a temperate climate: case studies on long-term effects of fertilization and crop rotation.
Provedor de dados: 21
Autores: Munkholm, Lars J.; Schjønning, Per; Petersen, Carsten T.
Two case studies on Danish sandy loams investigated long-term effects of fertilization and crop rotation. Case Study 1 compared a diversely cropped organically farmed soil (DFG(1)) with a conventionally farmed soil predominantly growing annual crops (DFA), both receiving animal manure.  In Case Study 2, a diversely cropped organically managed soil DFG(2)) receiving animal manure was compared with an almost exclusively cereal cropped conventionally farmed soil receiving no animal manure (CCC). A multi-level experimental strategy was followed to compare integrating field methods with specialized laboratory methods. Ease of tillage was described in the field and characterized using a drop shatter field test and by measuring aggregate tensile strength. Fitness...

Macro- and microscale gaseous diffusion in a Stagnic Luvisol as affected by compaction and reduced tillage
Provedor de dados: 21
Autores: Simojoki, Asko; Fazekas-Becker, Orsolya; Horn, Rainer.
Intensification of mechanical agriculture has increased the risk for soil compaction and deformation. Simultaneously, reduced tillage practices have become popular due to energy saving and environmental concerns, as they may strengthen and improve the functioning of structured soil pore system. Soil aeration is affected by both compaction and reduced tillage through changes in soil structure and in the distribution of easily decomposable organic matter. We investigated whether a single wheeling by a 35 000 kg sugar-beet harvester in a Stagnic Luvisol derived from loess near Göttingen, Germany, influenced the gas transport properties (air permeability, gaseous macro- and microdiffusivities, oxygen diffusion rate) in the topsoil and subsoil samples, and...

Bayesian analysis of the linear reaction norm model with unknown covariate
Provedor de dados: 21
Autores: Su, G.; Madsen, P.; Lund, M.S.; Sørensen, D.; Korsgaard, I.R.; Jensen, J.
The reaction norm model is becoming a popular approach for the analysis of G x E interactions. In a classical reaction norm model, the expression of a genotype in different environments is described as a linear function (a reaction norm) of an environmental gradient or value. A common environmental value is defined as the mean performance of all genotypes in the environment, which is typically unknown. One approximation is to estimate the mean phenotypic performance in each environment, and then treat these estimates as known covariates in the model. However, a more satisfactory alternative is to infer environmental values simultaneously with the other parameters of the model. This study describes a method and its Bayesian MCMC implementation that makes...

Autores: Jaffuel, Goeffrey; Blanco-Perez, Ruben; Büchi, Lucie; Mäder, Paul; Fliessbach, Andreas; Charles, Raphael; Degen, Thomas; Turlings, Ted C.J.; Campos-Herrera, Raquel.
Conservation agriculture is arising as an alternative to conventional agriculture with the aim to have a reduced impact on the environment. This includes the use of cover crops to conserve soil quality by limiting soil erosion, adding organic matter, and enhancing soil nutrient content, as well as water availability, which are all factors that can greatly influence the presence of soil organisms. In the current study, we investigated whether winter cover crops can enhance the persistence of entomopathogenic nematodes (EPN) over the winter season. In a first trial we augmented EPN populations in plots without (bared) and with the cover crops, pea (Pisum sativum) or mustard (Brassica juncea). In late autumn, individual mini-plots in each of the three...

Pflanzenstärkungsmittel sind nicht nur im Bioanbau verbreitet, auch manch anderer Betrieb setzt auf ihre Wirkung, obwohl die Werbung oft viel mehr verspricht, als die «Wundermittel» beim genauen Hinsehen in der Praxis bewirken können. Pflanzenstärkungsmittel, die gemäss Düngeverordnung für den Anbau zugelassen sind, sind im Bioanbau nur dann erlaubt, wenn sie in der offiziellen Hilfsstoffliste für den biologischen Anbau aufgeführt sind. Neben den Handelsprodukten sind selbst hergestellte Aufgüsse und Tees (z.B. Brennnesseljauche) in Gebrauch, auf die hier aber nicht näher eingegangen wird.

Udbytte, frugtkvalitet og angreb af sygdomme i økologisk æbleproduktion bestemmes af et samspil mellem faktorer som tilgængelighed af vand og gødning, grundstammen, plantetætheden og bekæmpelse af sygdomme og skadedyr.    Tidligere forsøg har vist, at den bedste frugtkvalitet og det laveste angreb af sygdomme i semi-tætplantede usprøjtede økologiske æbler (planteafstand på ca. 1,6 m) blev opnået ved relativ lav kvælstof tilgængelighed fra jordens egen mineralisering (se DARCOFenews).

The character of demand in mature organic food markets: Great Britain and Denmark compared
Provedor de dados: 21
Autores: Wier, Mette; O'Doherty Jensen, Katherine; Andersen, Laura Mørch; Millock, Katrin; Rosenkvist, Lars.
We investigate the organic food market in two selected European countries, Great Britain and Denmark, identifying main differences and similarities. We focus particularly on consumer preferences and priorities, labelling schemes, supply and sales channels, as a basis for assessing market stability and prospects for future growth. We employ a unique set of household panel data that includes information on stated values and concerns, as well as registered purchasing behaviour. Most organic food on both markets is produced and processed by large-scale industrialised units and distributed through concentrated mainstream sales channels, consumer confidence being sustained at present by organic labelling schemes that appear to function well. However, a parallel...

Background  Agricultural production is challenged by the limitation of non-renewable resources. Alternative fertilizers are promoted but they often have a lower availability of key macronutrients, especially phosphorus (P). Biological inoculants, the so-called bio-effectors (BEs), may be combined with these fertilizers to improve the nutrient use efficiency.  Methods  The goal of this study was to assess the potential of three BEs in combination with alternative fertilizers (e.g., composted manure, biogas digestate, green compost) to promote plant growth and nutrient uptake in soils typical for various European regions. Pot experiments were conducted in Czech Republic, Denmark, Germany, Italy, and Switzerland where the same variety of maize was grown in...

Autores: Horsted, K.; Allesen-Holm, B.H.; Hermansen, J.E.
1. Studies on the sensory profiling of male broiler breast meat were carried out to evaluate the effect of two very different broiler breeds (JA757 and New Hampshire), two different feed types (broiler and grower feed) and age at  slaughter (82 and 110 d).  2. The sensory profiling consisted of a pilot study, 4 training sessions, and finally the assessment. During the training session a panel of 9 assessors defined 17 attributes, which were used to describe the smell, texture  and flavour of the breast fillets. Each attribute was evaluated on a 15-cm unstructured line scale.  3. The breast meat became significantly less hard, and more juicy and tender in the New Hampshire at 110 d of age, whereas the opposite was found in JA757, which also acquired a more...

Stress and disease resilience differences related to emergence time for first feeding in farmed rainbow trout (Oncorhynchus mykiss)
Provedor de dados: 21
Autores: Gesto, Manuel; Madsen, Lone; Andersen, Nikolaj R.; Jokumsen, Alfred.
Salmonid individuals show a relatively high variability in the time required to abandon the gravel nest where they hatch, the so-called "emergence time". Different behavioral and physiological traits have been shown to be associated to that emergence time in wild salmonids. In general, early- and late-emerging fish have traits resembling those of proactive and reactive stress coping styles, respectively. Proactive fish are considered to be more resilient to stress and probably to disease, so it was hypothesized that fish with different emergence time have different ability to resist repeated episodes of stress without suffering deleterious effects on their welfare or health status. In this study, rainbow trout eyed eggs were hatched and larvae were...

Simulation of Above-Ground Suppression of Competing Species and Competition Tolerance in Winter Wheat Varieties
Provedor de dados: 21
Autores: Olesen, Jørgen E.; Hansen, Preben Klarskov; Berntsen, Jørgen; Christensen, Svend.
Cereal crop species and varieties differ in competitive ability against weeds mainly as influenced by differences in canopy architecture. The FASSET crop model was used to separate the effects of a number of crop traits on the suppressive ability of winter wheat varieties and the ability to tolerate weeds. The model simulated the competition between different varieties of winter wheat and a sown grass mixture for light, water and nitrogen. Crop physiological parameters of eight varieties and one variety mixture were estimated from measurements in a 3-year field experiment. The parameters estimated were thermal time from emergence to flag leaf appearance, thermal time from flag leaf appearance to anthesis, thermal time from anthesis to yellow ripeness,...

Autores: Cabral, Ricardo N; Marouelli, Waldir A; Lage, Daniel AC; Café-Filho, Adalberto C.
The objective of this study was to analyze the temporal progress of septoria leaf spot of tomato, caused by Septoria lycopersici, in different irrigation systems. The experiment was carried out in an organic farming system, in a randomized block design with three replicates. Six irrigation systems were evaluated: GO1L: one drip-line per row of plants; GO2L: two drip-lines; SU: furrow; MIsub: microsprinkler below plant canopy; MIalta: microsprinkler above plant canopy; AS: overhead sprinkler irrigation. Water management strategies varied with soil moisture tensions. Irrigation by drip systems was carried out when soil water tensions reached 15-30 kPa (high moisture), whereas for SU the trigger soil tension was 30-60 kPa (moderate moisture). All other...

Reducing milk induced cross-sucking of group housed calves by an environmentally enriched post feeding area
Provedor de dados: 21
Autores: Ude, Gracia; Georg, Heiko; Schwalm, Anja.
Group housing of calves is an animal-friendly natural and economic way of raising calves. One major disadvantage of artificial milk feeding in group housing systems, however, is the incidence of cross-sucking.  The main objective of this study was the evaluation of tructural and technical modifications of the feeding stall of an automatic teat feeder and the environmentally enriched feeding area in relation to a reduction of cross-sucking after finishing a milk meal.  The experiment was carried out with 168 female calves (German Holstein) of one origin randomly assigned to two treatments: control group and optimized group with a furnished post feeding area and an exercise yard with environmental enrichment. Calves were fed by an automatic teat feeder...

Autores: Dasko, L'ubomír; Drímal, Jozef; Klimekova, Marta; Urgeová, Eva.
Organic agricultural products have increasing share of the food market in Europe. The questions related to benefits of organic versus conventionally produced agricultural crops  are of increasing meaning. In our paper we have focused on assessment of the reaction of the immunity system of potato tubers from both agricultural systems on an external controlled attack of Phytophthora infestans, a pathogenic microorganism. The reaction of organic and conventional potato tubers was expressed via determination of chlorogenic acid. The content of chlorogenic acid in organic potato tubers increased 1.3 times after an attack, compared to potato tubers without a microbial attack. In conventional potato tubers, the increase was 4 times higher in the same way of...

Socio-cultural processes behind the differential distribution of organic farming in Denmark - a case study
Provedor de dados: 21
Autores: Risgaard, Marie-Louise; Frederiksen, Pia; Kaltoft, Pernille.
Conversion to organic farming, along with driving forces and barriers, has been explored intensively during the past decade, while studies on localization and impacts of local socio-cultural processes on conversion to and diffusion of organic farming have been scarce. Concentrations of organic farms in Denmark have been identified at the county level, and moreover there appeared to be large within-county variation in the density of organic farms. The present study explores the local aspects of conversion to organic farming and the factors that may help explain the variations in density and distribution of organic farms within smaller areas. The study is based on nine qualitative interviews with organic farmers from two neighboring areas, referred to as...

Compound-Specific δ15N and δ13C Analyses of Amino Acids for Potential Discrimination between Organically and Conventionally Grown Wheat
Provedor de dados: 21
Autores: Paolini, M.; Ziller, L.; Laursen, K.H.; Husted, S.; Camin, F.
We present a study deploying compound-specific nitrogen and carbon isotope analysis of amino acids to discriminate between organically and conventionally grown plants. We focused on grain samples of common wheat and durum wheat grown using synthetic nitrogen fertilizers, animal manures, or green manures from nitrogen-fixing legumes. The  measurement of amino acid δ15N and δ13C values, after protein hydrolysis and derivatization, was carried out using gas chromatography−combustion−isotope ratio mass spectrometry (GC-C-IRMS). Our results demonstrated that δ13C of glutamic acid and glutamine in particular, but also the combination of δ15N and δ13C of 10 amino acids, can improve the discrimination between conventional and organic wheat compared to stable...

Autores: Branco, Marina Castelo; Liz, Ronaldo S de; Alcântara, Flávia A; Martins, Hélio AG; Hanson, James C.
O projeto "Agricultura Apoiada pela Comunidade" (AAC) é uma alternativa de mercado utilizada na Europa e nos EUA. Neste mercado alternativo, os produtores oferecem a sua produção aos consumidores, sob a forma de cestas de alimentos, alguns meses antes de iniciarem a produção de suas culturas. Algum tempo depois, durante alguns meses, os consumidores irão receber os produtos. Atualmente, diversos países têm uma parcela significativa da sua população vivendo na pobreza. Por isso, diversas políticas públicas foram desenhadas nesses países com o objetivo de reduzi-la. O estímulo à agricultura urbana é uma dessas políticas. No entanto, frequentemente, os produtores urbanos pobres têm dificuldades para adquirir os insumos necessários para manter a sua produção....

Cultivating market relations - diversification in the Danish organic production sector following market expansion
Provedor de dados: 21
Autores: Thorsøe, Martin H.; Noe, Egon.
Developing a model to characterize the influence of the market on organic production has long been sought within agro-food studies. This paper explores how the market influences organic production by looking at the relationship between the market and producers’ engagement in trust and quality building as well as farm level production strategy in the Danish organic food market. Our perspective on the organic market is based on Actor-Network Theory (ANT) and, using qualitative interviews, we identify four market agencements, arrangements of actors endowed with agency: 1) standardizing market agencement, 2) personalizing market agencement 3) specializing market agencement and 4) aesthetifying market agencement. The market agencements enact multiple versions...

The effect of catch crop species on selenium availability for succeeding crops
Provedor de dados: 21
Autores: Stavridou, Eleftheria; Young, Scott D.; Thorup-Kristensen, Kristian.
Background and Aims    Selenium (Se) is an essential nutrient for humans and animals. In order to ensure an optimal concentration of Se in crops, Se fertilisers are applied. Catch crops may be an alternative way to increase Se concentrations in vegetables.    Methods    Three experiments in Denmark between 2007–10 investigated the ability of catch crops (Italian ryegrass, fodder radish and hairy vetch) under different fertiliser regimes to reduce soil Se content in the autumn and to increase its availability in spring to the succeeding crop.    Results and Conclusions    The catch crops (Italian ryegrass and fodder radish) increased water-extractable Se content in the 0.25–0.75 m soil layer in only one of the experiments. Selenium uptake by the catch crops...

Organic products – a matter of public or private values?
Provedor de dados: 21
Autores: Millock, Katrin; Wier, Mette; Andersen, Laura Mørch.
In this paper, we use a unique combination of questionnaire data and real market purchase data on organic food to examine whether stated values can predict purchase behaviour. We are particularly concerned about revealing to which extent organic goods represent private or public benefits, because this has important implications for the need for public intervention.  Our data cover around 2000 households during 1997-2001 and it is combined with a survey administered on the same panel in 2001. We distinguish between private use values (health, taste and freshness attributes) and public non-use values (environmental and animal welfare attributes). We find that public values are on average valued much more than private values according to consumers’ own...

Autores: Elmholt, S.; Schjønning, P.; Munkholm, L.J.; Debosz, K.
In order to improve our understanding of soil aggregation, we have studied the relative importance of bonding and binding mechanisms, especially how they scale according to aggregate size and how they are influenced by farming system and different management options. Topsoil samples were collected from four arable sandy loam soils found as two pairs (FP1 and FP2) of neighbouring fields. One of the fields in FP2 had been grown for decades with annual cash crops without application of organic manures, while the other three fields had been managed with diversified crop rotations and manure dressings. Aggregates were segregated from the bulk soil by promoting brittle failure. The samples of soil structural units were fractionated to 4-8 mm, 0.5-1 mm and...

Einstellung der Verbraucher zu Alternativen zur Ferkelkastration ohne Betäubung im ökologischen Landbau: Qualitative Ergebnisse aus Deutschland
Provedor de dados: 21
Autores: Heid, Astrid; Hamm, Ulrich.
In order to avoid the occurrence of boar taint, castration of piglets without pain relief is a common practice in pork production. Due to increasing animal welfare concerns, the practice will be banned in organic agriculture from 2012 and alternative methods will have to be implemented. An important factor for the successful implementation of such alternatives is consumers’ acceptance of the methods, as consumers’ daily buying decisions are crucial to the further development of the organic pork sector. Thus, this paper explores organic consumers’ attitudes towards piglet castration without pain relief and three alternative methods and examines which aspects of these alternatives are important to consumers of organic products. The analysis of nine focus...

Migration und Ausbreitung der Kirschfruchtfliege innerhalb von Obstanlagen – Möglichkeit der biologischen Bodenbehandlung
Provedor de dados: 21
Autores: Daniel, Claudia; Wyss, Eric.
The European cherry fruit fly (Rhagoletis cerasi) is the only pest insect which makes a  insecticide treatment of cherry fruit necessary. With regard of residue free cherries a biocontrol  method for R. cerasi by soil applications seems attractive. However, soil treatments can only be  effective if the migration of flies is low. In order to examine the potential of soil treatments and to  understand the dispersal behaviour of R. cerasi in orchards, experiments using nettings to cover the  soil were conducted. The experiments were arranged in commercial, organically managed orchards. The nettings reduced fruit infestation by 90%. In addition, it was shown that the flies move only very short distances (less than 5 m) within orchards. Thus, soil treatments...

Preliminary studies on using LAB strains isolated from spontaneous sauerkraut fermentation in combination with mineral salt, herbs and spices in sauerkraut and sauerkraut juice fermentations
Provedor de dados: 21
Autores: Wiander, Britta; Korhonen, H. J. T.
The use of mineral salt, herbs and spices in combination with isolated lactic acid bacteria strains in sauerkraut fermentation was studied. Mineral salt differs from ordinary salt because NaCl is partially replaced by KCl. The mineral salt contains 28% KCl and 57% NaCl. The final NaCl content in the sliced white cabbage mixture was 0.5%. In approximately 20 hours the pH dropped to the desired level. All the pressed sauerkraut juices had a good microbiological quality. The sensory quality of all pressed juices was found to be either good or acceptable.

In this study, we compare the economic performance of organic trout farms to conventional trout and organic agricultural farms. Farm account statistics from Statistic Denmark using financial performance indicators like the degree of profitability and farm solvency ratio shows an impressive organic trout sector. Though organic trout farms could not generate enough income from farm assets in 2010 and 2011, they picked up in 2012. Generally, organic trout farms tend to be equal or better in generating income per unit value of assets and have higher solvency ratios, indicating lower probability of default than alternative conventional trout farms and organic agricultural farms. An average organic trout farm was able to generate incomes of 8% per unit value of...

Ældre marker med kløvergræs kan beskytte grundvandet mod nitrat
Provedor de dados: 21
Autores: Eriksen, J.; Vinther, F.P.; Søegaard, K.
Ændringen i EU's landbrugspolitik (CAP) indebærer en afkobling af landbrugsstøtten og en afvikling af den nuværende hektarstøtte.     Derved øges græsmarkernes værdi fordi græs vil konkurrere bedre med de øvrige grovfoderemner rent prismæssigt.  I fremtiden forventes derfor en betydelig højere græsandel i kvægbrugenes sædskifter end det er tilfældet i dag.    Samtidig betyder strukturudviklingen, at kvæggårdene bliver større og et stigende antal brug ikke kan afgræsse alle marker i sædskiftet, da afgræsning langt fra gården er besværlig eller helt uforeneligt med de daglige rutiner.     Disse forhold forventes at bevirke, at der på kvægbrugene fremover vil være græsmarker, som får lov til at blive betydeligt ældre end de 2-3 år, der hidtil har været mest...

Organic farming often has to deal with a scarcity of readily available nutrients, and this is in contrast to chemical farming which relies on soluble fertilisers. The present study was conducted to ascertain the effect of different combinations of organic manures, rice residues and biofertilisers in organic farming of wheat. The field experiments were carried out on the research farm of Indian Agricultural Research Institute (IARI), New Delhi in 2006-07 and 2007-08. Treatments consisted of a control (no fertiliser) and six fertiliser treatments, namely, farmyard manure (FYM), vermicompost (VC), FYM + rice residue (RR), VC + RR, FYM + RR + biofertilisers (B), and VC + RR + B. FYM and VC were applied on nitrogen basis (60 kg ha-1), whereas RR was applied at...

It is necessary therefore, to determine the functional requirements for a future energy-efficient robotic bioproduction system from the perspective of various stakeholders, together with the development of a high-level framework for designing and prototyping the common functionalities of mobile robots. This study presents technical guidelines for the design of a plant nursing robot. The methodology uses Quality Function...

Efeito do suco de alho (Allium sativum L.) sobre endoparasitas gastrintestinais de ovinos.
Provedor de dados: 21
Autores: Santos, Fernanda Carlini Cunha; Vogel, Fernanda Silveira Flores; Monteiro, Silvia Gonzales.
Os parasitas gastrintestinais de ovinos causam enormes prejuízos a pecuária, tendo como principais sinais clínicos: redução na produção de carne, leite e lã, anemia, diarréia, anorexia e morte súbita. O tratamento preconizado é basicamente através da administração de produtos químicos, sendo que estes estimulam o aparecimento da resistência parasitária. Nesse contexto, a fitoterapia é uma modalidade de tratamento medicinal que vem crescendo muito nestes últimos anos. Com o intuito de avaliar a eficácia do suco de alho (Allium sativum) sobre infecções helmínticas foram utilizados 18 ovinos divididos em três tratamentos. Nos grupos I e II, os animais receberam respectivamente, 15g e 30g de alho em forma de suco, uma vez ao dia durante três dias consecutivos,...

Corporate Responsibility: The Stakeholder Paradox Reconsidered
Provedor de dados: 21
Autores: Jensen, Karsten Klint.
Is it legitimate for a business to concentrate on profits under respect for the law and ethical custom? On the one hand, there seems to be good reasons for claiming that a corporation has a duty act for the benefit of all its stakeholders. On the other hand, this seems to dissolve the notion of a private business; but then again, a private business would appear to be exempted from ethical responsibility. This is what Kenneth Goodpaster has called the stakeholder paradox: either we have ethics without business or we have business without ethics.    Through a different route, I reach the same solution to this paradox as Goodpaster, namely that a corporation is the instrument of the shareholders only, but that shareholders still have an obligation to act...

Issues of scale for environmental indicators
Provedor de dados: 21
Autores: Stein, A.; Riley, J.; Halberg, N.
The value of environmental indicators largely depends upon the spatial and temporal scale that they represent. Environmental indicators are dependent upon data availability and also upon the scale for which statements are required. As these may not match, changes in scales may be necessary. In this paper a geostatistical approach to analyse quantitative environmental indicators has been used. Scales, defined in terms of resolution and procedures, are presented to translate data from one scale to another: upscaling to change from high resolution data towards a low resolution, and downscaling for the inverse process. The study is illustrated with three environmental indicators. The first concerns heavy metals in the environment, where the zinc content is...

Hermetia illucens meal as fish meal replacement for rainbow trout on farm
Provedor de dados: 21
Autores: Stadtlander, Timo; Stamer, Andreas; Buser, Andrea; Wohlfahrt, Jens; Leiber, Florian; Sandrock, Christoph.
In a 7-week on-farm feeding trial rainbow trout(Oncorhynchus mykiss) were provided with a diet containing 28% mechanically de-fatted insect meal prepared from larvae of the black soldier fly, Hermetia illucens (HIM) and compared to a control that received a certified organic and fishmeal based diet. In the test diet insect meal replaced almost 50% of the fishmeal. The whole experiment was conducted under practical conditions on an organically certified rainbow trout farm in Switzerland. Fish of initially 66.5±2.3 g body weight were grown to 125±4.5 g and assessed for their growth performance, as well as analysed for their proximate composition, feed conversion ratio, fatty acid contents and organoleptic properties.

Structural differences in wheat (Triticum aestivum), hemp (Cannabis sativa) and Mischanthus (Mischanthus ogiformis) affect the quality and stability of compost as growing medium
Provedor de dados: 21
Autores: Dresbøll, Dorte Bodin; Thorup-Kristensen, Kristian.
Physical properties as well as process parameters were examined in three different composts based on plant residues. The wheat compost was a mixture of clover-grass and wheat straw in a ratio of 3:5, the Mischanthus compost was composed of the same materials and contained Mischanthus straw in addition in a ratio of 3:2.5:2, and the hemp compost was based on clover-grass, wheat and hemp straw also in a ratio of 3:2.5:2. The wheat and Mischanthus composts both had an initial C/N ratio of 26 and process parameters such as nitrogen losses and mineralisation pattern did not differ between the two compost types. The hemp compost had a much lower initial C/N ratio of 16 as the hemp straw was harvested fresh, resulting in higher losses and more mineralised...

1. Organic farming (OF) enhances top soil organic carbon (SOC) stocks in croplands compared with conventional farming (CF), which can contribute to sequester C. As farming system differences in the amount of C inputs to soil (e.g. fertilization and crop residues) are not enough to explain such increase, shifts in crop residue traits important for soil C losses such as litter decomposition may also play a role.    2. To assess whether crop residue (leaf and root) traits determined SOC sequestration responses to OF, we coupled a global meta-analysis with field measurements across a European-wide network of sites. In the meta-analysis, we related crop species averages of leaf N, leaf-dry matter content, fine-root C and N, with SOC stocks and sequestration...

Winter cereal yields as affected by animal manure and green manure in organic arable farming
Provedor de dados: 21
Autores: Olesen, Jørgen Eivind; Askegaard, Margrethe; Rasmussen, Ilse A.
The effect of nitrogen (N) supply through animal and green manures on grain yield of winter wheat and winter rye was investigated from 1997 to 2004 in an organic farming crop rotation experiment in Denmark on three different soil types varying from coarse sand to sandy loam. Two experimental factors were included in the experiment in a factorial design: 1) catch crop (with and without), and 2) manure (with and without). The four-course crop rotation was spring barley undersown with grass/clover - grass/clover - winter wheat or wheat rye - pulse crop. All cuttings of the grass-clover were left on the soil as mulch. Animal manure was ap-plied as slurry to the cereal crops in the rotation in rates corresponding to 40% of the N de-mand of the cereal crops....

Autores: Paulsen, Hans Marten; Schrader, Stefan; Schnug, Ewald.
Auf die in den 50er und 60er Jahren publizierten Theorien zur Bodenfruchtbarkeit von Hans Peter Rusch wird im organisch-biologischen Landbau heute noch Bezug genommen. Zu nennen sind hier der Rusch-Test zur Einstufung der biologischen Qualität der organischen Substanz und von Böden, die Systematisierung des Abbaus organischer Substanz im Boden und der Humusbildung sowie die Flächenkompostierung. Ruschs Lehren zielen auf eine Verbesserung der Bodengare durch effiziente Zufuhr organischer Substanz und Humusbildung sowie auf die Verbesserung der Ausnutzung von Nährstoffen. Gegen den Geist seiner Zeit grenzte sich Rusch von der Mineraldüngung ab und hebt die auch heute unbestrittene Rolle des Humus für die Bodenfruchtbarkeit hervor. Die tatsächliche Bedeutung...

Different goods, different effects: exploring the effects of generalized social trust in large-N collective action
Provedor de dados: 21
Autores: Sønderskov, Kim Mannemar.
Does generalized social trust help solve large-N collective action problems? This paper argues so, offering a novel explanation for the relationship: People tend to cooperate if they expect others to be cooperating, which implies that people holding generalized social trust more readily cooperate in large-N dilemmas because they expect that most people will cooperate. The paper tests the explanation in a rigorous design. The analyses show a positive, robust effect of generalized social trust on public good provision, but no effect is found in a joint product situation. This supports the hypothesis, indicating that trust specifically enhances cooperation in collective action dilemmas.

Solid-state 13C NMR characterization of surface fire effects on the composition of organic matter in both soil and soil solution from a coniferous forest
Provedor de dados: 21
Autores: Näthe, Kerstin; Delphis, F. Levia; Steffens, Markus; Michalzik, Beate.
Wildfires change the chemical composition of soil organic matter (SOM). Since the effects of fires on organic matter (OM) in soil solution are largely unknown, we sought to compare the quality of dissolved organic matter (DOM) and total organic matter (TOM =DOM +particulate OM) between burned and control sites. The sites were subjected to a low-intensity surface fire in a coniferous forest in Germany dominated by spodic Cambisols derived from Triassic sandstone. Soil solutions from three different soil horizons (O, Ah, Bw), and throughfall (TF) were analyzed using solid state 13C NMR spectroscopy, allowing us to track the initial fire impact on OM vertically through the soil profile and 70 days after the fire. In addition, organic layer samples were...

Partizipative Landschaftsentwicklung im Ökologischen Landbau – Fallbeispiele und Entwicklungsperspektiven
Provedor de dados: 21
Autores: van Elsen, Thomas.
Bei der Initiierung und Installation von Naturschutzzielen in der Kulturlandschaft spielt das Prinzip der Partizipation eine zunehmende Rolle. Um heute im Ökologischen Landbau bewusst Landschaft zu gestalten und zu entwickeln, ist die aktive Einbindung der Bewirtschafter in die Entwicklung von Maßnahmen sinnvoll. Entscheidend für den Erfolg von Bestrebungen, durch partizipative Ansätze zu einer Weiterentwicklung der Kulturlandschaft beizutragen, ist nicht nur der funktionierende Dialog zwischen den beteiligten Akteuren und eine inter- bzw. transdisziplinäre Begleitforschung, sondern auch, ob der Prozess der Landschaftsgestaltung selber zu einem „Dialog“ mit der Landschaft, mit ihrem Arteninventar und mit ihren Entwicklungspotentialen gestaltet werden kann.

Strawberry blossom weevil (SBW), Anthonomus rubi Herbst (Coleoptera: Curculionidae) and European tarnished plant bug (ETB), Lygus rugulipennis Poppius (Hetereoptera: Miridae), cause significant damage to strawberry and raspberry crops. Using the SBW aggregation pheromone and ETB sex pheromone we optimized and tested a single trap for both species. A series of field experiments in crops and seminatural habitats in five European countries tested capture of the target pests and the ability to avoid captures of beneficial arthropods. A Unitrap containing a trapping agent of water and detergent and with a cross vane was more efficient at capturing both species compared to traps which incorporated glue as a trapping agent. Adding a green cross vane deterred...

The effects of six fungus strains (Deuteromycotina: Hyphomycetes) on the mortality of different life stages of the European cherry fruit fly, Rhagoletis cerasi Loew (Diptera: Tephritidae), were assessed in a series of laboratory experiments. All fungus strains were able to cause mycosis to larvae and adults of R. cerasi. However, virulence varied considerably among the strains. Effects on  L3-larvae were negligible. In contrary, adults were highly susceptible to fungus infection. Beauveria bassiana and Paecilomyces fumosoroseus caused 90 to 100% mortality and had a strong influence on fecundity. Metarhizium anisopliae also showed reliable effects. The pathogenicity of Paecilomyces farinosus was low. Higher conidia concentrations lead to higher mortality,...

Exploring The Gap Between Attitudes And Behaviour: Understanding Why Consumers Buy Or Do Not Buy Organic Food
Provedor de dados: 21
Autores: Padel, Susanne; Foster, Carolyn.
The purpose of the paper is to explore the values that underlie consumers purchasing decisions of organic food. It draws on data from focus groups and laddering interviews with a total of 181 regular and occasional consumers of organic food that were contrasted with survey results of other studies.  The results show that most consumers associate organic at first with vegetables and fruit and a healthy diet with organic products. Fruit and vegetables are also the first and in many cases only experience with buying organic product. The decision-making process is complex and the importance of motives and barriers may vary between product categories. Future research should consider tradeoffs that consumers make between values and product as well as consumer...

Wheat/forage legume intercropping in organic grain system: an answer to both weed and nitrogen deficiency issues
Provedor de dados: 21
Autores: Amosse, Camille; Celette, Florian; Jeuffroy, Marie-Hélène; David, Christophe.
Organic grain system managers have to find solutions to nitrogen deficiency and weed infestation. It is especially true when no animals are present on the farm to justify the use of forage legumes despite their interests in the crop succession. Our study focused on the role of four legume cover crop species inserted in a succession of winter wheat and maize on both problems. This insertion consisted in relay-intercropping the legumes under the canopy of wheat. Cover crops were maintained on the field after the harvest of the cereal until the sowing of the subsequent maize crop. The performance of the three crops of the succession was monitored as well as weed development and nitrogen dynamic in the soil-plant system. On the one hand, our results showed...

The secrets of Koberwitz: The diffusion of Rudolf Steiner’s Agriculture Course and the founding of Biodynamic Agriculture
Provedor de dados: 21
Autores: Paull, John.
Rudolf Steiner presented his Agriculture Course to a group of 111, farmers and others, at Koberwitz (Kobierzyce, Poland) in 1924. Steiner spoke of an agriculture to ‘heal the earth’ and he laid the philosophical and practical underpinnings for such a differentiated agriculture. Biodynamic agriculture is now practiced internationally as a specialist form of organic agriculture. The path from proposal to experimentation, to formalization, to implementation and promulgation played out over a decade and a half following the Course and in the absence of its progenitor. Archival material pertaining to the dissemination of the early printed editions of ‘The Agriculture Course’ reveals that within six years of the Course there was a team of more than 400...

Autores: Duval, Julie; Bareille, Nathalie; Fourichon, Christine; Madouasse, Aurélien; Vaarst, Mette.
Organic dairy farmers must live up to the organic goal of ‘good health’ in respect the organic principles and regulation. Veterinarians could be the organic dairy farmers’ expected sparring partners in reaching this goal but have found difficulties to establish advisory relationships with them. The objectives of this study are −from organic dairy farmers’ points of view- (i) to describe farmers’ objectives and strategies regarding herd health, (ii) to describe private veterinarians’ roles in farmers’ animal health promotion strategies and (iii) to identify farmers’ reasons for accepting veterinarians in an advisory role. Fourteen organic dairy farmers were interviewed using qualitative research interviews. Data collection and analysis was performed using a...

Alternativ bekæmpelse af æbleskurv i økologisk æbledyrkning
Provedor de dados: 21
Autores: Lindhard, Hanne; Paaske, Klaus; Bengtsson, Marianne; Hockenhull, John.
Æbleskurv forårsaget af svampen Venturia inaequalis er den skadevolder, som oftest forhindrer en god ydre kvalitet af æbler. Skurv er skyld i brune til sorte pletter på frugten og kan i nogle år og på nogle sorter angribe så kraftigt, at æblerne bliver meget små, misdannede og fuldstændig uegnede til spisning. Denne svampesygdom er årsag til en stor udbytte- og en meget stor kvalitetsnedgang i økologisk produktion.

Effect of pulsed electric fields pre-treatment on mass transport during the osmotic dehydration of organic kiwifruit
Provedor de dados: 21
Autores: Traffano-Schiffo, Maria Victoria; Tylewicz, Urszula; Castro-Giraldez, Marta; Fito, Pedro J.; Ragni, Luigi; Dalla Rosa, Marco.
Recently, some authors have applied pulsed electric fields (PEF) as a pre-treatment of osmotic dehydration,  showing a faster kinetics of dehydration. Osmotic dehydration of fruit tissue shows complex mass transfer mechanism  associated with active and passive transports of the vegetal matrix, usually driven by electrolytes. The aim  of this work was to analyze the effect of different PEF values (100, 250, 400 V/cm) as a pre-treatment of the osmotic  dehydration (61.5 °Bx, up to 120 min) on mass transport mechanism of organic kiwifruit.  A thermodynamic model able to describe the mass transfer and tissue deformation in kiwifruit was developed. It  was possible to conclude that pulsed electric field as a pre-treatment, remove a part of the native...

Alternative versus conventional attitudes in higher agricultural education
Provedor de dados: 21
Autores: Rasmussen, Jesper; Kaltoft, Pernille.
From radical positions it is argued that it will take paradigmatic transformations to develop a sustainable agriculture and that values and attitudes have to be changed. To find out if teachers and students in higher agricultural education are motivated for radical changes a survey based on the Alternative-Conventional Agriculture Paradigm Scale (ACAP-scale) was conducted. The ACAP-scale shows how people relate to the alternative and conventional agricultural paradigm and it shows their overall understanding of how agriculture works and relates to the physical and social environment. This study showed that the ACAP-scale is a suitable method for quantitative assessment of attitudes to agriculture in a broader context. Among students and faculty members at...

Controlled traffic farming increased crop yield, root growth, and nitrogen supply at two organic vegetable farms
Provedor de dados: 21
Autores: Hefner, M.; Labouriau, R.; Nørremark, Michael; Kristensen, Hanne Lakkenborg.
Increased farm machinery weight in agricultural production results in soil compaction. Controlled traffic farming (CTF) restricts traffic to permanent lanes, thereby creating traffic free beds for crop production. Field experiments were conducted at two organic vegetable farms in Denmark, on a sandy loam (2013–2016) and on coarse sand (2013–2015) to investigate CTF effects compared with random traffic farming (RTF) on vegetable yield, root growth, and soil mineral nitrogen (N). Root growth was measured using minirhizotrons. White cabbage, potato, and beetroot yield increased by 27%, 70% and 42%, respectively, in CTF compared with RTF in 2015 and winter squash indicated a yield increase of 43% on sandy loam in 2016. White cabbage (2015) and potato, beetroot...

Could phosphite be a new fungicide for organic farming?
Provedor de dados: 21
Autores: Speiser, Bernhard; Tamm, Lucius.
Quote from the article    "Potassium phosphite, also called «phosphonate», is a salt of phosphonic acid with the formula K2HPO3.    It should not be confounded with phosphates, nor with the organophosphorous insecticides which are also called «phosphonates». Potassium phosphite can be used as a fungicide against oomycetes in various crops. In the early 1990ies, it was extensively tested on organically grown grapevines in Switzerland. It was effective against downy mildew (Plasmopara viticola), and blocked the disease up to 3 days after infection. Phosphite was mobile and very persistent in plants and could be detected in grapes harvested one year after the last application. Analyses of 53 wine samples reveiled that the treatment inevitably leads to...

Boundaries between soil compartments formed by microporous hydrophobic membranes (GORE-TEX®) can be crossed by vesicular-arbuscular mycorrhizal fungi but not by ions in the soil solution
Provedor de dados: 21
Autores: Mäder, P.; Vierheilig, H.; Alt, M.; Wiemken, A.
Various container systems have been described in which soil regions available to hyphae only are separated from the mycorrhizal root region by 30–60 μm mesh screens to study nutrient exchange between plants and fungi in the mycorrhizal symbiosis. The screens designed up to now prevent penetration by roots but allow easy passage of fungal hyphae as well as diffusion or mass flow of water and nutrient solutions. We tested hydrophobic microporous polytetrafluorethylene (PTFE) membranes (GORE-TEXR) with 5 to 15 μm diameter pores in an attempt to obtain a better seal between compartments and to prevent uncontrolled nutrient transport by diffusion or mass flow. We found that these membranes completely prevented diffusion or mass flow of ions between two soil...

Functional Biodiversity
Provedor de dados: 21
Autores: Wolfe, Martin.
Modern conventional agriculture is characterized by monocultures. These are less productive in terms of biomass than natural plant communities, which are usually complex mixtures of species and varieties, and they also require more inputs. A central question for organic agriculture is therefore how far we can move from monocultural to polycultural systems in order to benefit from this biodiversity without loss of yield. Rotations are one way of increasing biodiversity, but other components of the EFRC research programme are relevant:    breeding programmes for wheat and kale aimed at producing crop populations rather than pure lines; variety and species mixtures, especially for cereals;    intercropping legumes with a vegetable rotation (companion...

Impact of spring warming on sowing times of cereal, potato and sugar beet in Finland
Provedor de dados: 21
Autores: Kaukoranta, Timo; Hakala, Kaija.
Historical data were used to determine if the warm springs experienced in recent decades have influenced time of sowing of spring cereals (barley, wheat and oats), potato and sugar beet in Finland. The start of the thermal growing season was used to represent all climatic factors affecting sowing time. Regional anomalies in sowing and start of growing season were computed for the years 1965–2007. The start of the growing season was 2–2.8 days earlier per decade, with a steeper increase since 1980. Sugar beet sowing advanced 2.5 (since 1980 5.2) and potato planting 3.4 (since 1980 4.5) days per decade, more than expected solely due to earlier starts to the growing season. Sowing of spring cereals advanced 0.6, 0.7 and 1.7 days per decade in the east, north...

BACKGROUND: The demand for organic food products has  increased during the last decades due to their probable  health effects, among others. A higher content of secondary metabolites such as carotenoids in organic food products has been claimed, though not documented, to contribute to increased health effects of organic foods. The aim was to study the impact of organic and conventional agricultural systems on the content of carotenoids in carrots and human diets. In addition, a human cross-over study was performed, measuring the plasma status of carotenoids in humans consuming diets made from crops from these agricultural systems.     RESULTS: The content of carotenoids in carrot roots and human diets was not significantly affected by the agricultural...

The purpose of this literature review was to  evaluate if it should be avoided to keep the cow  and calf together after birth because of the risk of  transmission of infectious pathogens from the cow to  the preweaning calf. The sources of transmission of  common infections in newborn calves are described.  E.coli, rotavirus, bovine coronavirus, Clostridium spp.,  Cryptosporidium spp., Giardia and Eimeria spp. are  ubiquitous, and infected calves can excrete extreme  numbers of microorganisms and cause contamination  of the environment. According to the literature, microorganisms in the environment represent a higher risk  than adults for transmission to the newborn, and hygienic  measures and good passive immune status of the  newborn are important...

Conventional farmers converting to organics has contributed to most of the rapid expansion of organic farming in recent years. The new organic farmers may differ from their more established colleagues, which may have implications for the development of the organic farming sector and its distinctiveness vis-à-vis conventional production and marketing practices. The aim of this study was to explore Norwegian organic dairy farmers’ personal and farm production characteristics, farming goals, conversion motives, and attitudes to organic farming, grouped by year of conversion (three groups). A postal survey was undertaken among organic dairy farmers (n = 161). The results show that the newcomers (converted in 2000 or later) were less educated than the early...

Autores: Aagaard-Hansen, J.; Larsen, C.E. Schou; Halberg, N.; Hjortsø, C.N.; Gausset, . Q.; Kabirizi, J.
Conventional research approaches have lost considerable momentum after their astonishing achieve-ments during the green revolution. The negative side of focusing rigorously on production improve-ment was eminent around 1980 and led to considerations of environmental, gender and equity aspects - making agricultural development much more complex than previously. In the search for new ways of addressing the persisting problems of food insecurity and malnutrition, new ways should be explored. Based on the experiences from three international, African research projects, the article argues the case of participatory action research and cross-disciplinarity as some of the key elements in future animal science research in developing countries.

Autores: Vogl, C. R.; Mölleken, H.; Lissek-Wolf, G.; Surböck, A.; Kobert, J.
The interest in hemp (non-drug Cannabis sativa L.) for skin care and cosmetic use is due to the high content of oil, especially unsaturated fatty acids in seed with technological and therapeutic effects. In a field trial on an organic farm, seed weight and content of fatty acids of 20 hemp varieties were surveyed on three different harvest dates. The dry matter seed yields ranged from 27-149 g m2. The varieties Ferimon-12, Fedora-19, and Bialobreszie produced high seed yields on all three harvest dates but yields were not significantly different from a large group of other varieties. Contents of palmitic acid range from 3.1 to 4.1%, of stearic acid from 0.1 to 1.9%, of oleic acid from 3.7 to 9.2%, of linoleic acid from 44.8 to 60.2%, of α-linolenic acid...

Inter-row hoeing for weed control in organic spring cereals – interactions with inter-row spacing and nitrogen rate
Provedor de dados: 21
Autores: Melander, Bo.
Inter-row hoeing has become increasingly important for weed control in organic spring cereals since the introduction of automatic steering systems. The technology requires a widening of current inter-row spacing for spring cereals in order to provide sufficient room for accurate operation of a hoe share between crop rows. However, there is considerable uncertainty about the optimal combination of inter-row hoeing, inter-row spacing and nitrogen rate in terms of weeding effectiveness and crop yield. The aim of this study was to investigate the effect on weed and crop growth of the interaction between five inter-row spacings (125, 150, 200, 250, and 300 mm) and two nitrogen rates (50 and 100 kg NH4-N ha-1). Three field experiments were conducted in spring...

Most studies on the effects of tanniferous plants on nematodes have examined forages but have neglected the woody plants. Therefore, in vitro effects of extracts from 3 woody plants (Rubus fructicosus, Quercus robur, Corylus avellana) have been tested on trichostrongyles and compared to sainfoin, a legume forage. Because some in vivo results indicated that the effects of tannins differed depending on the parasitic species and/or stages, the effects  were measured on third-stage larvae (L3) and adult worms of Teladorsagia circumcincta, Haemonchus contortus and Trichostrongylus colubriformis. The effects of plant extracts varied according to the plant sources, the parasite species and stages. For the woody plants, significant inhibitory effects were obtained...

The viability of cotton-based organic farming systems in India
Provedor de dados: 21
Autores: Eyhorn, Frank; Ramakrishnan, Mahesh; Mäder, Paul.
Cotton farmers in many developing countries are facing decreasing marginal returns due to stagnating yields and high input costs. Conversion to organic management could offer an alternative. In a two year comparative study in central India covering 170 cotton fields, organic farms achieved cotton yields that were on par with those in conventional farms, whereby nutrient inputs and input costs per crop unit were reduced by half. Due to 10–20% lower total production costs and a 20% organic price premium, average gross margins from organic cotton fields were 30–40% higher than in the conventional system. Although the crops grown in rotation with cotton were sold without premium, organic farms achieved 10–20% higher incomes from agriculture. In addition to...

Welche Landwirtschaft für Afrika? Akzeptanz und Potenzial biologischer Methoden
Provedor de dados: 21
Autores: Nicolay, Gian L.
Afrika, dieser grosse, vielseitige und verkannte Kontinent kämpft zurzeit heftig um die Ausrichtung seiner  Landwirtschafts – und Ernährungspolitik. Die Lage ist dramatisch. Südlich des Sahel leiden von den knapp 800 Mio Menschen mindestens ein Drittel an  Hunger und Misere. Ein Grossteil der Ackerböden und Weidegründe ist stark beschädigt und gibt nur noch Bruchteile der üblichen Erträge her. Wälder und Savannenlandschaften sowie Biodiversität stehen unter Dauerdruck und fallen ungebremst dem Landhunger zum Opfer.  Hat die biologische Landwirtschaft das Potenzial, wesentlich zur Ernährungssicherheit, zum guten Leben und zur Regeneration der Bodenfruchtbarkeit beizutragen? Das Forschungsinstitut für biologischen Landbau (FiBL) hat gute Gründe, daran zu...

Nye forskningsmodeller og et anderledes helhedssyn
Provedor de dados: 21
Autores: Kledal, Paul Rye.
De økologiske fødevarekæder er i nogle sammenhænge organiseret som et alternativ til den traditionelle agroindustrielle fødevarekæde, mens de i andre sammenhænge følger den traditionelle kæde fra "jord til bord". Hvorfor gør de det? Og hvilke forskelle og ligheder findes der i organiseringen af de økologiske fødevarekæder inden for mælkeprodukter, grøntsager og kød (fjerkræ, svin, får og kvæg)? Artiklen beskriver nogle af de nye modeltilgange, som SAMSON forskningsprojektet arbejder ud fra i et forsøg på  at forklare nogle af disse forskelle og ligheder.

Contribution of organic agriculture to macro-economic and environmental performance of the countries with economies in transition
Provedor de dados: 21
Autores: Znaor, Darko.
The current agricultural operations cause a number of environmental and socio-economic problems and raise substantial ethical doubts. The call for the shift of the present agricultural paradigm and practices is acknowledged all across Europe. Ten years after the economic transition, the agricultural sector in Central and Eastern Europe (CEE) still undergoes essential transformation. In spite of the policy efforts to restore the pre 90 inputs, low-external input agriculture prevails in most CEE countries. The transition to a market economy caused a huge price disparity between the agricultural commodities and agricultural inputs. The high prices of agri-chemicals and low prices of agricultural produce forced farmers to reduce agricultural inputs or refrain...

Provedor de dados: 21
Autores: Marin, Aldrin Martin Pérez; Menezes, Rômulo Simões César; Silva, Emanuel Dias; Sampaio, Everardo Valadares de Sá Barreto.
Gliricidia sepium é uma leguminosa arbórea que tem sido utilizada em sistemas em aléias no semi-árido nordestino por apresentar bom desenvolvimento em condições de estresse hídrico. Entretanto, há pouca informação disponível sobre o efeito da introdução dessa espécie nos agroecossistemas da região. No presente estudo, objetivou-se avaliar a influência da distância de plantas de Gliricidia sepium sobre características da cultura do milho e do solo e microclima no Agreste Paraibano. O estudo foi realizado no município de Esperança (PB), em área de 0,5 ha, onde, em 1996, foram plantadas fileiras de G. sepium espaçadas 6 m entre si e com 1 m entre as árvores. Nesta área, em 2002, foram delimitadas quatro parcelas de 6 x 8 m e, em cada parcela, foi estabelecido...

Welchen organischen Handelsdünger für den ökologischen Gemüsebau? [Which organic fertilizer for organic horticulture?]
Provedor de dados: 21
Autores: Laber, H.
Welcher der organischen Handelsdünger für den ökologischen Gemüsebau ist der beste? Und welche Rolle spielt die Aufbereitung der Düngemittel? Zur Beantwortung dieser Frage wurden seit Beginn der 90er Jahre im deutschsprachigen Raum über 30 Versuche angelegt, bei denen die verschiedenen organischen Handelsdünger miteinander verglichen wurden. Nach den vorliegenden Versuchsergebnissen erwiesen sich Rizinusschrot, die Horn- und Haarmehlprodukte und auch Blutmehl als gleich wirksame Düngemittel. Auch Maltaflor zeigte vergleichbare Resultate. Mit dem sehr preisgünstig zu beziehenden Rapsextraktionsschrot und den  Leguminosenschroten konnten zumeist akzeptable Ergebnisse erzielt werden.

Effect of information about organic production on beef liking and consumer willingness to pay
Provedor de dados: 21
Autores: Napolitano, Fabio; Braghieri, Ada; piasentier, Edi; Favotto, Saida; Naspetti, Simona; Zanoli, Raffaele.
The present study was aimed to assess the effect of information about organic production on beef liking and consumer willingness to pay. Mean scores of perceived liking were higher for organic beef (OB) as  compared to conventional beef (CB). Expected liking scores were higher for OB than for CB. For OB the expected liking was significantly higher than the perceived liking expressed in blind conditions (negative disconfirmation), whereas for CB no difference was observed. Consumers completely assimilated their liking for OB in the direction of expectations. Consumers showed a willingness to pay for OB higher than the suggested price (P &lt; 0.001), the latter corresponding to the local commercial value for organic beef.  We conclude that the information...

Intensively managed grasslands are dominated by highly productive grass-clover mixtures. Increasing crop diversity by inclusion of competitive forbs may enhance biomass production and sustainable biofuel production. Here we examined if one or all of three forbs (chicory, Cichorium intybus L.; caraway, Carum carvi L.; plantain, Plantago lanceolata L.) included in ryegrass-red clover mixtures enhanced above- and below-ground productivity, and assessed their biofuel potentials, based on a three-year experiment with and without fertilisation as cattle slurry. We determined herbage yield, standing root biomass, and estimated methane energy output and greenhouse gas (GHG) emissions per energy unit using life cycle assessment. Results showed that...

Nutrient supply from organic amendments applied to  unvegetated soil, lettuce and orchardgrass
Provedor de dados: 21
Autores: Hammermeister, A.M.; Astatkie, T.; Jeliazkova, E.A.; Warman, P.R.; Martin, R.C.
Organic sources of nutrients are increasingly being used in horticultural and certified organic production. The nutrient-supplying potentials of poultry manure compost (PM), feather meal (FM), alfalfa meal (AA) and vermicastings (VC) and an unamended control were measured in a growth room experiment. The amendments were applied at rates equivalent to 200, 400 and 800 kg total N ha-1 to a soil of low fertility. Nitrogen supply rates and concentrations were measured over 6 mo in unvegetated pots using PRS™ probes and KCl extraction, respectively. Biomass of lettuce (Lactuca sativa L.) and orchardgrass (Dactylis glomerata L.) and N uptake of orchardgrass were measured. Repeated measures analysis revealed significant amendment × rate × time interaction effects...

Rachel Carson, a Voice for Organics - the First Hundred Years
Provedor de dados: 21
Autores: Paull, John.
Rachel Carson has been described as "an early supporter of organic farming". Publishing in 1962, she awoke a generation past, to the false promises of the “war on weeds”, the “war against the insects” and “better living through chemistry”. Carson wrote to a friend: “there would be no peace for me if I kept silent”. She asked the world to consider: “Can anyone believe it is possible to lay down such a barrage of poisons on the surface of the earth without making it unfit for all life?”. Carson has been described by TIME Magazine as one of “the 100 most influential people of the 20th century” and her book has been described as “the most influential book of the past 50 years”- yet on the occasion of the centenary of her birth, the author found that university...

Nitrat im Grundwasser: Der Streit um die Ursachen
Provedor de dados: 21
Autores: Haas, Guido.
Der Organische Landbau hat in Mitteleuropa seinen Ausgangspunkt unter anderem in der von Rudolf Steiner initiierten Biologisch-dynamischen Wirtschaftsweise. Anlass für Rudolf Steiner, den sogenannten 'Landwirtschaftlichen Kurs' abzuhalten, waren Anfragen von Landwirten zur Überwindung der "degenerierten Produktqualität für Ernährung ('Nährwert') und Saatgut" (STEINER 1924, SCHAUMANN 1996). Die Auswirkung der mineralischen Düngung stand seinerzeit im Mittelpunkt der kritischen Betrachtung.   Allerdings wurden damals nur in vergleichsweise geringen Mengen mineralische Stickstoffdünger ausgebracht. In Deutschland wurden in den Jahren 1928, 1938/39 und 1950/51 lediglich 14, 25 bzw. 26 kg N/ha mineralisch gedüngt. Nach dem Zweiten Weltkrieg bildete das Kernziel...

State of organic seeds in France
Provedor de dados: 21
Autores: Rey, F; Sinoir, N.; Wohrer, J.; Touret, C.; Mazollier, C.
A comprehensive range of investigations carried out between 2010 and 2012 provided information on the state of organic seeds in France. Results fit with the hypothesis that the market is a significant factor influencing the choice of seeds and cultivars (local cultivars, landraces, modern cultivars). Expectations and practices of producers selling on a local market (i.e., direct sale) differ radically from those of producers selling to long food supply chains.  This study showed that the availability and use of organic seeds have significantly improved over the last three years. A vast majority of organic producers willingly use organic seeds, with, on average, 45-70 % (cereals), and 75%-100 % (vegetables) of organic seeds being planted on farms. However,...

Autores: Heyden, Bertold.
Bisher war der ökologische Landbau in Bezug auf die verfügbaren Getreidesorten weitgehend abhängig vom Züchtungsfortschritt im konventionellen Landbau. Immer mehr entwickelt sich dieser Fortschritt aber zum Nachteil: Im Weizenanbau, wo in der konventionellen Landwirtschaft für ein ganz anderes Ertrags- und Stickstoffniveau gezüchtet wird, entsteht das Problem, dass unter ökologischen Anbaubedingungen die erwünschte Backqualität nicht mehr erreicht wird. Und auch die Züchtungsmethoden – Labormethoden bis hin zur Gentechnik – entsprechen nicht den Idealen des Ökolandbaus.

Bovine respiratory syncytial virus and bovine coronavirus in Swedish organic and conventional dairy herds
Provedor de dados: 21
Autores: Wolff, Cecilia; Emanuelson, Ulf; Ohlson, Anna; Alenius, Stefan; Fall, Nils.
Background: Infections with bovine respiratory syncytial virus (BRSV) and bovine coronavirus (BoCV) are endemic  to the cattle populations in most countries, causing respiratory and/or enteric disease. It has been demonstrated that herds can remain free from these infections for several years also in high prevalence areas. Organically managed (OM) dairy herds have been shown to have lower seroprevalence of both viruses compared to conventionally managed (CM) herds. The objective of this study was to challenge the hypothesis of a lower occurrence of BRSV and BoCV in OM compared to CM dairy herds.  In November 2011, May 2012 and May 2013 milk samples from four homebred primiparous cows were collected in  75 to 65 OM and 69 to 62 CM herds. The antibody status...

Group membership and certification effects on incomes of coffee farmers in Uganda
Provedor de dados: 21
Autores: Ssebunya, Brian Robert; Morawetz, Ulrich B.; Schader, Christian; Stolze, Matthias; Schmid, Erwin.
Discrepancies in certification effects on smallholder incomes have been found in scientific literature. Unobserved farmer-group heterogeneity is a likely reason. For the long-standing Robusta coffee farmer-groups in Uganda, we find no significant effect of certification on net-farm income. But, we find 20 percentage point differences in net-farm income between certified and non-certified farmers explained by membership duration. In contrast, the recently founded certified Arabica coffee farmer-groups have positive net-farm income effects of 151 per cent, partly explained by a higher degree of vertical integration. With or without certification, long-standing group membership is found to have positive income effects.

Estimating the incidence of entomopathogenic nematodes in soil by the use of bait insects
Provedor de dados: 21
Autores: Nielsen, Otto; Skovgaard, Ib Michael; Philipsen, Holger.
Soil samples were stored and baited in different ways in order to develop a bait method that could estimate the level of steinernematid nematodes in soil in a time efficient way. The method was based on incidence (proportion of samples with a given species of Steinernema). Tenebrio molitor (Coleoptera) larvae were used as bait and it was concluded that: 1) Repeated baiting in a later period improved the bait result; 2) Extension of the bait periods from one to two weeks was not necessary; 3) The precision of the estimated incidence did not improve noteworthy by taking more than 60-80 samples; 4) The minimum time required to analyse one soil sample was 6 minutes.

Autores: de Vries, Franciska T.; Liiri, M.E.; Bjørnlund, Lisa; Bowker, M.A.; Christensen, Soren; Setälä, Heikki; Bardgett, Richard.
Soils deliver several ecosystem services including carbon sequestration and nutrient cycling, which are of central importance to climate mitigation and sustainable food production. Soil biota play an important role in carbon and nitrogen cycling, and, although the effects of land use on soil food webs are well documented, the consequences for their resistance and resilience to climate change are not known. We compared the resistance and resilience to drought — which is predicted to increase under climate change 2,7 — of soil food webs of two common land-use systems: intensively managed wheat with a bacterial-based soil food web and extensively managed grassland with a fungal-based soil food web. We found that the fungal-based food web, and the processes of...

Delayed nutrient application affects mineralisation rate during composting of plant residues
Provedor de dados: 21
Autores: Dresbøll, Dorte Bodin; Thorup-Kristensen, Kristian.
The hypothesis that delayed addition of nutrient rich material to compost would influence the mineralisation pattern was investigated by studying N turnover in compost based on wheat straw and clover-grass hay. After 7½ weeks of composting almost twice as much N was mineralised when the addition of of some of the N-rich clover-grass hay was postponed, suggesting that this influenced the microbial succession. The delayed addition resulted in a second temperature peak and a decline in the pH. Despite the altered conditions no significant effect was observed on the weight loss or loss of C and N. In conclusion, compost processes can in a simple way be affected by delayed substrate application leading to a higher nutrient availability without altering other...

Systems Theory as a Scientific Approach towards Organic Farming
Provedor de dados: 21
Autores: Høgh-Jensen, Henning.
Systems theory differs from classic analytical science by producing statements in the context of a descriptive system rather than seeking to reduce a complex problematic situation to researchable entities. This paper analyses the validity and applicability of systems theory as a scientific approach towards organic farming. The world-views on which organic farming and systems theory build, respectively, are discussed and the methodological consequences of these world views are clarified.  The world-view inherent in organic farming (the ontological level), as reflected in stewardship towards nature, the ethic of animal husbandry, and the cycling processes in nature, is harmonious with the underlying ideas of systems theory as regards a hierarchical structure...

The ICROFS (International Centre for Research in Organic Food Systems) has conducted an analysis of the effects of organic research in Denmark (1996-2010) on the Danish organic sector and on society in general. Over these 15 years, three national programs and one program with European collaboration have been implemented in Denmark, financed via special government grants that amounted to just over 500 million DKK (approx. € 67 million—or approximately $ 80 million). The analysis itself was carried out as a compilation of information from three perspectives, each of which has been independently documented:  • Interviews with (representatives of) end-users of results from research and development (R&amp;D) investigating their assessment of the challenges in...

Relative ovicidal effect of soil microfungi on thick-shelled eggs of animal-parasitic nematodes
Provedor de dados: 21
Autores: Thapa, Sundar; Meyling, Nicolai V.; Katakam, Kiran Kumar; Thamsborg, Stig Milan; Mejer, Helena.
Thick-shelled eggs of animal-parasitic ascarid nematodes can survive and remain infective in the environment for years. The present study was conducted to assess the effect of two species of soil microfungi (Pochonia chlamydosporia and Purpureocillium lilacinum) on the development and survival of eggs (all of faecal origin) of three ascarid species, Ascaridia galli (chicken roundworm), Toxocara canis (canine roundworm) and Ascaris suum (pig roundworm), in vitro. Ascarid eggs were embryonated on water agar with or without one fungal species, and viability of the eggs was evaluated on days 7, 14, 21, 28, 35 and 42 post set up (p.s.). By day 14 p.s., P. chlamydosporia had reduced the viability of A. galli and T. canis eggs by 70-86% and 52-67%, respectively,...

Risk and Risk Management in Organic and Conventional Cash Crop Farming in Norway
Provedor de dados: 21
Autores: Koesling, Matthias; Ebbesvik, Martha; Lien, Gudbrand; Flaten, Ola; Valle, Paul Steinar; Arntzen, Halvard.
This study presents empirical insight into organic and conventional cash crop farmers' perceptions of risk and risk management strategies, and identifies socio-economic variables linked to these perceptions. The data originate from a questionnaire survey of farmers in Norway. The results indicate that organic farmers perceived themselves to be less risk averse than conventional farmers. For both groups, crop prices and yield variability were the two top rated sources of risk, followed by institutional risks. The two groups evaluated risk management strategies quite similarly; favoured strategies were good liquidity and to prevent and reduce crop diseases and pests. The farmers' evaluation of sources of risk and choice of risk strategies depended on various...

Transição para agricultura de base ecológica: um processo social.
Provedor de dados: 21
Autores: Pacífico, Daniela A.; Soglio, Fábio Kessler Dal.
O presente artigo tem como objetivo analisar o projeto de transição para uma cafeicultura orgânica que foi realizado em duas comunidades rurais no norte do estado do Paraná, em 2003. A partir da pesquisa de campo e das consultas bibliográficas sobre a Agroeocologia e a perspectiva teórica orientada pelo ator (POA) constatou-se que o método de transição, ao se utilizar de um modelo preestabelecido de atividades de transição, impossibilitou a participação do ator social e não contribuiu com o processo de empoderamento desses agricultores acerca da nova cafeicultura que se estabelecia. É destacado que, para o processo de transição ter se dado por completo não apenas o método foi determinante, mas, sobretudo, as conseqüências geradas por ele ainda no decorrer...

Consumer attitudes towards organic versus conventional food with specific quality attributes
Provedor de dados: 21
Autores: Stolz, H.; Stolze, M.; Hamm, U.; Janssen, M.; Ruto, E.
This paper describes the findings from a consumer survey conducted as part of the EU-funded research project QualityLowInputFood (QLIF). The objective was to segment occasional organic consumers with regard to their preferences for organic, conventional and conventional-plus products, i.e., conventional products with a specific attribute that also applies to organic products. In other words, these conventional-plus products are placed between organic and conventional food products. In addition, we aimed at analysing differences between consumer segments regarding their price sensitivity and attitudes towards food. The survey used choice experiments to investigate occasional organic consumer preferences for the different types of products. In subsequent...

Demonstration-scale protein recovery by lactic acid fermentation from grass clover – a single case  of the production of protein concentrate and press cake silage for animal feeding trials
Provedor de dados: 21
Autores: Santamaria-Fernandez, Maria; Ambye-Jensen, Morten; Damborg, Vinni K.; Lübeck, Mette.
There is an increasing interest in green biorefineries for the utilization of green biomass to provide a variety of valuable products. Proteins can be extracted from green biomasses such as alfalfa, clover, or grass and separated into protein-rich concentrates suitable for feeding to monogastric animals. Press cake suitable for feeding ruminant animals is also produced. Full implementation of such a green biorefinery requires knowledge and experience of production at demonstration scale. Moreover, product evaluation in animal-feeding trials requires a large amount of product. There has been collaboration in Denmark between several partners from industry and academia to assess the practicality and scalability of a green biorefining plant producing protein...

Sulphate leaching in an organic crop rotation on sandy soil in Denmark.
Provedor de dados: 21
Autores: Eriksen, J; Askegaard, M.
Sulphate leaching losses may reduce the long-term possibility of maintaining the S supply of crops in low input farming systems. Sulphate leaching and S balances were investigated in an organic dairy/crop rotation (barley [Hordeum vulgare]  grass-clover [Lolium perenne/Trifolium repens]  grass-clover  barley/pea [Pisum arvénse]  winter wheat [Tritucum aestivum]  fodder beet [Beta vulgaris]) from 1994 until 1998. The importance of climatic conditions and use of different organic manure types at different application rates for sulphate leaching were investigated and related to the concurrent nitrate leaching. As an average of years, sulphate leaching from the crop rotation was 20 kg S ha-1, which was equivalent to 60% of the total input to the rotation....

Interactions between nutrition and gastrointestinal  infections with parasitic nematodes in goats
Provedor de dados: 21
Autores: H., Hoste; J.F., Torres-Acosta; V., Paolini; A., Aguilar-Caballero; E., Etter; Y., Lefrileux; C., Chartier; C., Broqua.
Parasitic nematodes of the digestive tract remain one of the main constraints to goat production both in temperate and tropical  countries. The usual mode of control of these gastrointestinal nematodes (GIN) based on the repeated use of anthelmintics  is now strongly questioned because of the increasing development of resistance to these molecules. Among the alternative  methods to anthelmintics currently available, the manipulation of host nutrition in order to improve the host resistance and/or  resilience to parasitic infections seems to represent one of the most promising options to reduce the dependence on conventional  chemotherapy and to favour the sustainable control of gastro intestinal nematode infections. This paper will review the available...

Effect of different levels of collembolan grazing on interspecific competition between microfungi, decomposition of organic matter and bio-availability of nitrogen
Provedor de dados: 21
Autores: Bach, Lisbet; Jørgensen, Helene B; Axelsen, Jørgen.
The effect of selective grazing by a collembolan (Folsomia fimetaria) on the reproduction and ability to degrade wheat straw by 2 species of microfungi was measured. The experiment was performed with 3 different grazing pressures and a control without grazing. The 3 grazing pressures correspond to an initial density of 10.000, 20.000 or 100.000 collembolans/m2. The density cannot however be directly related to a field density, because the soil column was only approximately 2 cm high.  Results show that the most preferred fungus to F. fimetaria, Alternaria infectoria, were only affected in terms of reproduction at the highest grazing pressure of 30 collembolans (as initial density). Both respiration rates and the content of bio-available nitrogen in the...

This model analysis of catch crop effects on nitrate retention covered three soil texture classes sand, loamy sand, sandy loam) and three precipitation regimes in a temperate climate representative for northern Europe (annual precipitation 709-1026 mm) for a period of 43 years.  Simulations were made with two catch crops (ryegrass and Brassica) with different rooting depths, and soil N effects in the next spring were analysed to 0.25, 0.75 and 2.0 m depth to represent the catch crop effect on following crops with different rooting depths. Nitrate retained without a catch crop was generally located in deeper soil layers. In the low precipitation regime the overall fraction of nitrate retained in the 0-2.0 m soil profile was 0.23 for the sandy soil, 0.69 for...

Small‐scale distribution of copper in a Technosol horizon  studied by nano‐scale secondary ion mass spectrometry
Provedor de dados: 21
Autores: Rennert, Thilo; Höschen, Carmen; Rogge, Derek; Steffens, Markus.
Rationale: In contaminated soil, copper (Cu) is commonly distributed among various very small particles. To enlighten the qualitative distribution of Cu in a contaminated Technosol (a soil developed from deposited technogenic material) on the sub‐micron scale, we used nano‐scale secondary ion mass spectrometry (NanoSIMS).  Methods: We studied seven areas (up to 40 μm × 40 μm) on a thin section of a soil horizon by NanoSIMS, measuring 12C−, 18O−, 32S−, 63Cu− and 56Fe16O−. We evaluated the NanoSIMS measurements with a novel digital image processing tool to enlighten the composition of measured areas and thus the distribution of Cu at the sub‐micron scale. Image processing comprised spatial and spectral smoothing, normalization, endmember extraction and...

Interactions between soil organic matter level and soil tillage in a growing crop: N mineralization and yield response
Provedor de dados: 21
Autores: Thomsen, I.K.; Sørensen, P.
Effects of organic matter management and soil loosening on the synchrony between soil N mineralization and crop N demand were studied in a field experiment. Four different levels of organic matter (OM) were applied to a crop rotation during 12 years by various applications of animal manure, straw incorporation and catch crop growing. A spring barley crop was grown to test the influence of the previous OM applications. Soil loosening with a row cultivator was carried out one, two or three times in the first part of the growth season to examine the potential for adjusting soil N mineralization by soil tillage in cropping systems with different OM input. Immediately before each of the soil loosenings and again after one, two and three weeks, plant biomass and...

Autores: Brozova, Ivana.
The present research was aimed at evaluating the economic performance of organic farm enterprises (legal entities) in the Czech Republic on the basis of their production base and financial health. The evaluation was carried out by means of specific financial indicators. The results recorded in the organic farming sector were confronted with those of the conventional agriculture. It stemmed from the analysis that conventionally farming legal entities, as opposed to the organically farming ones, tend to have higher average assets per hectare of farmland. Secondly, as for the structure of assets, fixed assets prevail substantially over current assets. Organic farms, on the contrary, have a significantly higher average value of external financial resources per...

Organic farming is knowledge intensive. To support farmers in improve yields and organic agriculture systems, there is a need to improve how knowledge is shared. There is an established culture of sharing ideas, successes and failures in farming. The internet and information technologies open-up new opportunities for knowledge exchange involving farmers, researchers, advisors and other practitioners. The OK-Net Arable brought together practitioners from regional Farmer Innovation Groups across Europe in a multi-actor project to explore how online knowledge exchange could be improved.

Phylogenetic analyses of sequences of the SSU–ITS–LSU nrDNA segment and the RPB1 gene showed that the arbuscular mycorrhizal fungus originally described as Diversispora omaniana does not belong to the genus Diversispora, but represents a separate clade at the rank of genus in the family Diversisporaceae of the order Diversisporales. The closest natural relatives of the fungus proved to be species of the genera Corymbiglomus and Redeckera. Consequently, the new genus was named Desertispora, and Di. omaniana was renamed De. omaniana comb. nov. In addition, the morphological and histochemical features of spores and mycorrhizal structures of a new Diversispora sp., Di. sabulosa, were described and the closest relatives of the species were determined based on...

Recommendable block sizes: a case study on Finnish official variety trials of barley cultivars
Provedor de dados: 21
Autores: Jauhiainen, Lauri; Öfversten, Jukka; Kangas, Arjo.
Well-established results in the current statistical literature imply that plant breeders should use incomplete block designs wherever spatial variability exists and the number of treatments is large. But the theoretical position does not indicate the recommendable number of cultivars in an incomplete block. In this study we used data from 28 official variety trials conducted in Finland during the period 2001-2005 to study theffect of block size on the efficiency of testing pairwise yield differences of barley cultivars and cultivar rankings. In previous trials some 6-7 cultivars have usually been included in one block. Our results imply that the efficiency of testing procedures could be improved by using a block size as small as 4-5. The results further...

Detailed longitudinal studies of the genetic stability of Pasteurella multocida ssp. multocida, the cause of fowl cholera, have not previously been carried out. Consequently, the aim of the present study was to provide detailed information on the genetic stability and diversity of P. multocida ssp. multocida in poultry flocks over time enabling new insight concerning the molecular epidemiology of this important poultry pathogen.  Longitudinal investigations of the rate and causes of mortality were carried out on two free-range layer farms (A and B) over a period of 11 months. The total mortality of two flocks, A1 and A2, on farm A were 62% and 91%, respectively, while the total mortality of a single flock B1 on farm B was 6%. Postmortem examinations were...

A continuous labelling approach to recover photosynthetically fixed carbon in plant tissue and rhizosphere organisms of young beech trees (Fagus sylvatica L.) using 13C depleted CO2
Provedor de dados: 21
Autores: Esperschütz, J.; Gattinger, A.; Buegger, F.; Lang, H.; Munch, J.; Schloter, M.; Winkler, J.
A continuous labelling experiment using 13C-CO2 was set up in open-top chambers in order to follow fluxes of assimilates from the plant into the rhizosphere. Labelling was performed for one growing season by adding low amounts of CO2 depleted in 13C to the atmosphere of the open-top chambers, resulting in a difference of ∆ 13C 5‰ V-PDB compared to ambient conditions. The label was recovered in both plant parts and soil microbial communities, analysed via phospholipid fatty acid (PLFA) side chains. PLFA 18:2ω6,9 showed a significant incorporation of the 13C label in October, indicating that fungi utilized plant derived carbon. In bacterial PLFA no label incorporation was detected, probably due to a lower use of rhizodeposits or a preference to older carbon...

Stor produktion af grovfoder og lav nitratudvaskning ved dyrkning af grønbyg med italiensk rajgræs efter kløvergræs
Provedor de dados: 21
Autores: Hansen, E.M.; Eriksen, J.; Vinther, F.P.
Har man problemer med kløvertræthed i sine marker kan en løsning være, at dyrke grønbyg (byg høstet ved begyndende skridning) med udlæg af italiensk (ital.) rajgræs. Nye forsøg beskrevet her viser, at dyrkning af grønbyg med udlæg af ital. rajgræs giver mulighed for at reducere udvaskningen af kvælstof (N) til et minimum og samtidig opnå en stor produktion af grovfoder. I modsætning hertil er der normalt stor risiko for udvaskning af kvælstof ved ompløjning af kløvergræs på sandjorde.

Künstliche Besamung von Ziegen
Provedor de dados: 21
Autores: Koopmann, Regine; Fischer, Peter.
Anders als bei Rindern und Schweinen ist die künstliche Besamung (KB) in der deutschen Ziegenzucht bislang ein kaum übliches Verfahren. Hauptursachen dafür sind der Umfang und die Strukturen der Zuchtpopulationen sowie die wirtschaftlichen Rahmenbedingungen für die Züchter. Andere Länder wie Frankreich, Schweiz, Spanien oder auch Schweden zeigen jedoch, dass durch konsequente Besamungszucht der züchterische Fortschritt erheblich gesteigert werden kann. Durch den Spermaeinsatz verschiedener Vatertiere kann wirksam der Inzuchtproblematik im Bestand begegnet werden. Gerade Halter kleinerer Bestände können so ohne eigenen Bock, dessen Geruchsbelästigung nicht zu unterschätzen ist, ihre Herde optimal reproduzieren. Ein genauso wichtiges Argument für die...

Eating Quality of Carrots (Daucus carota L.) Grown in One  Conventional and Three Organic Cropping Systems over Three Years
Provedor de dados: 21
Autores: Edelenbos, Merete.
The eating quality of carrots (Daucus carota L.) was investigated to evaluate the impact of cropping systems (one conventional and three organic systems) and growing years (2007, 2008, and 2009) on root size, chemical composition, and sensory quality. The content of dry matter, sugars, polyacetylenes, and terpenes as well as the sensory quality and root size were related to the climate during the three growing years. A higher global radiation and a higher temperature sum in 2009 as compared to 2007 and 2008 resulted in larger roots, higher contents of dry matter, sucrose, total sugars, and total polyacetylenes, and lower contents of terpenes, fructose, and glucose. No differences were found between conventional and organic carrots with regard to the...

Are there alternatives to copper for controlling grapevine downy mildew in organic viticulture?
Provedor de dados: 21
Autores: Dagostin, Silvia; Schärer, Hans-Jakob; Pertot, Ilaria; Tamm, Lucius.
Downy mildew caused by the obligate biotrophic oomycete Plasmopara viticola is one of the most important and devastating diseases of grapevine. Copper-based fungicides are used to control the disease in organic vineyards. However, since 2006, copper use has been limited by an European Commission regulation. In this study conducted from 2004 to 2007, we tested materials that might replace copper in organic viticulture, under controlled greenhouse and field conditions at two locations in Europe (northern Italy and Switzerland). We tested 112 different treatments, including biocontrol agents, materials of animal origin, homeopathic preparations, inorganic materials, microbial extracts, natural derivatives, plant extracts, physical methods and synthetic...

Influence of different cultivation methods on carbohydrate and lipid compositions and digestibility of energy of fruits and vegetables
Provedor de dados: 21
Autores: Jørgensen, Henry; Knudsen, Knud Erik Bach; Lauridsen, Charlotte.
BACKGROUND  Environmental as well as cultivation factors may greatly influence the chemical composition of plants. The main factors affecting the chemical composition of foodstuff are level and type of fertilizer (conventional and organic cultivation systems), location or soil type, and year of harvest. Organic foods are defined as products that are produced under controlled cultivation conditions characterized by the absence of synthetic fertilisers and very restricted use of pesticides. Very limited information is available regarding the impact of organic cultivation systems on the composition of carbohydrates and fatty acids of fruits and vegetables. The objective was to investigate the influence of organic and conventional cultivation systems on the...

This study investigated the effect of, and interactions between, US Brown Swiss (BS) genetics and season on milk yield, basic composition and fatty acid profiles, from cows on low-input farms in Switzerland. Milk samples (n = 1,976) were collected from 1,220 crossbreed cows with differing proportions of BS, Braunvieh and Original Braunvieh genetics on 40 farms during winter-housing and summer-grazing. Cows with more BS genetics produced more milk in winter but not in summer, possibly because of underfeeding potentially high-yielding cows on low-input pasture-based diets. Cows with more Original Braunvieh genetics produced milk with more (i) nutritionally desirable eicosapentaenoic and docosapentaenoic acids, throughout the year, and (ii) vaccenic and...

Convergence of Participatory Guarantee Systems and Internal Control Systems in an IFOAM European pilot project
Provedor de dados: 21
Autores: van den AKKER, J.
Organisation into Participatory Guarantee Systems was the main model for compliance with organic farming specifications until the beginning of the 1990s, even if it was not officially recognised as such. Control and certification by an independent body then became a requirement (standard EN NF 45011). This European project, initiated by IFOAM in 2005, showed that, among other things, an Internal Control System can provide a guarantee equivalent to that of a certification by an independent body, but on the basis of different tools: the transparency of local networks, the improvement of practices at the group level and the involvement of consumers. As a result, recognition of the Participatory Guarantee Systems by public authorities would reinforce consumer...

How Dr. Ehrenfried Pfeiffer Contributed to Organic Agriculture in Australia
Provedor de dados: 21
Autores: Paull, John.
Ehrenfried Pfeiffer (1899-1961) was 25 years old when Rudolf Steiner (1861-1925) delivered his eight lectures on agriculture from 7th June to 16th June 1924. In those eight lectures at Koberwitz, Rudolf Steiner laid the basis for biodynamic agriculture. Steiner advocated an agriculture informed by anthroposophy, and that the ideas he expounded in the eight agriculture lectures should be developed by experiments, practice and observation. Ehrenfried Pfeiffer took up this task and he spent the rest of his life in the pursuit. Pfeiffer published his book ‘Bio-Dynamic Farming and Gardening’ in 1938. It was the first popular account of bio-dynamic agriculture. In that book Pfeiffer presented the practical results of more than a decade of farming practice and...

Anthelmintic effects of forage chicory (Cichorium intybus) against gastrointestinal nematode parasites in experimentally infected cattle
Provedor de dados: 21
Autores: Peña-Espinoza, Miguel; Thamsborg, Stig Milan; Desrues, Olivier; Hansen, T. V. A.; Enemark, Heidi L.
Two experiments studied the effects of dietary chicory against gastrointestinal nematodes in cattle. In Experiment (Exp.) 1, stabled calves were fed chicory silage (CHI1; n = 9) or ryegrass/clover hay (CTL1; n = 6) with balanced protein/energy intakes between groups. After 16 days, all calves received 10 000 Ostertagia ostertagi and 66 000 Cooperia oncophora third-stage larvae (L3) [day (D) 0 post-infection (p.i.)]. In Exp. 2, calves were assigned to pure chicory (CHI2; n=10) or ryegrass/clover (CTL2; n = 10) pastures. After 7 days, animals received 20 000 O. ostertagi L3/calf (D0 p.i.) and were moved regularly preventing pasture-borne infections. Due to poor regrowth of the chicory pasture, CHI2 was supplemented with chicory silage. At D40 p.i. (Exp. 1)...

Estimation of genetic parameters for novel functional traits in Brown Swiss cattle
Provedor de dados: 21
Autores: Kramer, M.; Erbe, M.; Bapst, B.; Bieber, A.; Simianer, H.
The aim of this study was to estimate genetic parameters and accuracies of breeding values for a set of functional, behavior, and conformation traits in Brown Swiss cattle. These traits were milking speed, udder depth, position of labia, rank order in herd, general temperament, aggressiveness, milking temperament, and days to first heat. Data of 1,799 phenotyped Brown Swiss cows from 40 Swiss dairy herds were analyzed taking the complete pedigree into account. Estimated heritabilities were within the ranges reported in literature, with results at the high end of the reported values for some traits (e.g., milking speed: 0.42±0.06, udder depth: 0.42±0.06), whereas other traits were of low heritability and heritability estimates were of low accuracy (e.g.,...

Somatic embryogenesis (SE) is the most striking and prominent example of plant plasticity upon severe stress. Inducing immature carrot seeds perform SE as substitute to germination by auxin treatment can be seen as switch between stress levels associated to morphophysiological plasticity. This experimental system is highly powerful to explore stress response factors that mediate the metabolic switch between cell and tissue identities. Developmental plasticity per se is an emerging trait for in vitro systems and crop improvement. It is supposed to underlie multi-stress tolerance. High plasticity can protect plants throughout life cycles against variable abiotic and biotic conditions. We provide proof of concepts for the existing hypothesis that alternative...

Autores: Forslund, A.; Ensink, J.; Battilani, A.; Kljujev, I.; Gola, S.; Raicevic, V.; Jovanovic, Z.; Stikic, R.; Sandei, L.; Fletcher, T.; Dalsgaard, A.
Clean water has become one of the main limiting factors in agricultural food production in Europe, especially for countries around the Mediterranean, who now face more severe and frequent seasonal water shortages. In order to overcome water shortages the European Water Framework Directive encourages and promotes the use of treated urban wastewater in agriculture. However, the use of poor quality water in agriculture poses potential health risks. The application of wastewater through subsurface drip irrigation lines could possibly overcome public health concerns by minimizing contact with wastewater by farmers, farm workers but it is uncertain if the risk for consumers of wastewater irrigated produces would be acceptable.

Background:   Organic pig production is expanding and amongst the objectives of organic farming are enhancing animal health and welfare. However, some studies have reported a higher prevalence of lameness and joint condemnation at slaughter in free-range/organic pigs than in conventionally raised pigs. Organic slaughter pigs have free-range housing in which indoor and outdoor access is compulsory, while in conventional farming the pigs are commonly confined to indoor pens. The present study evaluated the effects of free-range and confined housing on lameness prevalence in a herd of 106 finisher pigs, and whether osteochondrosis and Erysipelothrix rhusiopathiae associated arthritis influences these effects. We also evaluated the association between clinical...

Autores: Alaru, Maarika; Talgre, Liina; Eremeev, Viacheslav; Tein, Berit; Luik, Anne; Nemvalts, Anu; Loit, Evelin.
The aim of organic agriculture is to produce food of high nutritional quality in sufficient quantity. Field experiments were conducted to evaluate the effect of organic and conventional growing systems on (i) total amounts and sup-ply of N taken up or applied to plants during a five year crop cycle period and (ii) crops total dry matter (DM) yield obtained during same period. The total DM yields from the organic treatments were 25–33% smaller than from the conventional treatments. The ratio of N output/N input was significantly the smallest in the organic treatment with cattle manure, where only 37% of all supplied N was used by plants during the crop cycle period. The organic fertiliser with faster mineralisation rate and splitting the application of...

Immunological effects of feeding macroalgae and various vitamin E supplements in Norwegian white sheep-ewes and their offspring
Provedor de dados: 21
Autores: Novoa-Garrido, Margarita; Aanesen, Lise; Lind, Vibeke; Larsen, Hans Jørgen S.; Jensen, Søren K.; Govasmark, Espen; Steinshamn, Håvard.
It is assumed that ewes raised in areas with long indoor winter feeding periods need to be supplemented with vitamins or other substances that help to maintain the health status of the animals. Various supplements are available on the market, but the most widely used supplemental antioxidant and vitamin E source is synthetic all-rac-α-tocopheryl acteate. The objective of the present study was to compare potential vitamin E and immune stimulant sources with synthetic vitamin E regarding bioactivity associated with immunological parameters in order to identify alternatives to synthetic vitamin E for small ruminants. Sources tested were meal of the seaweed Ascophylum nodosum and natural RRR-α- tocopheryl acetate. Forty pregnant ewes were randomly allocated to...

Effect of replacing organic grass-clover silage from primary growth with regrowth on N digestion in dairy cows
Provedor de dados: 21
Autores: Naadland, Sondre Stokke; Steinshamn, Håvard; Krizsan, Sophie Julie; Randby, Åshild T.
Clover proportions, and thereby chemical composition of herbage, differ between primary growth (PG) and regrowth (RG) in organic managed grass-clover fields. The characteristics of PG and RG silages suggest different supplementary feeding strategies to sustain an efficient milk production in dairy cows. Silage made of the RG generally offers more crude protein (CP) in the diet than silage made of the PG because of an increasing proportion of clover later in the season. Additionally, grass and clover have different amino acid (AA) profiles. His has been suggested to be the first limiting AA in grass silage, while Met has been suggested to be the primarily limiting AA in red clover silage. Eight rumen cannulated Norwegian Red cows were used in two replicated...

Vitamin contents in forage herbs
Provedor de dados: 21
Autores: Elgersma, A.; Søegaard, K.; Jensen, S.K.
Grasslands provide an important part of the feed used by domestic and wild ruminants. Fresh forages are an important natural source of vitamins in ruminant diets. Most studies in forages have been carried out with perennial ryegrass and legume species such as white clover. As yield and quality data of broad-leaf grassland species are scarce, the aim of this study was to obtain novel information on vitamins in a number of herb species compared to a grass-clover mixture and to get insight into species differences and seasonal patterns across the various harvests and years. Seven herb species and a perennial ryegrass-white clover mixture were investigated in a cutting trial with four harvests (May–Oct) during 2009 and 2010. Vitamin concentrations were highest...

Autores: Wyss, Gabriela.
Landwirtschaftliche Böden können Rückstände von Organochlorpestiziden (OCP) enthalten, welche bis vor 30 Jahren in der konventionellen Landwirtschaft zugelassen waren. Wie das bekannte DDT gehört Dieldrin zu diesen OCPs. Der insektizide Wirkstoff Dieldrin ist im Boden sehr schlecht abbaubar. Das Mittel wurde bis zu Beginn der 70er-Jahre breit im Acker-, Obst-, Wein- und Gartenbau gegen viele Schädlinge eingesetzt. Dann verlor es seine Zulassung. Leider sind auch in heute biologisch bewirtschafteten Parzellen solche Verbindungen vorhanden. Insbesondere Kürbisgewächse sind in der Lage, OCPs aufzunehmen.

Autores: Slagboom, Margot; Kargo, Morten; Edwards, David; Sørensen, Anders Christian; Thomasen, Jørn Rind; Hjortø, Line.
The overall aim of this research was to characterize the preferences of Danish dairy farmers for improvements in breeding goal traits. The specific aims were (1) to investigate the presence of heterogeneity in farmers’ preferences by means of cluster analysis, and (2) to associate these clusters with herd characteristics and production systems (organic or conventional). We established a web-based survey to characterize the preferences of farmers for improvements in 10 traits, by means of pairwise rankings. We also collected a considerable number of herd characteristics. Overall, 106 organic farmers and 290 conventional farmers answered the survey, all with Holstein cows. The most preferred trait improvement was cow fertility, and the least preferred was...

Autores: Keller, Martina; Oberson, Astrid; Annaheim, Kathrin E.; Tamburini, Federica; Mäder, Paul; Mayer, Jochen; Frossard, Emmanuel; Bünemann, Else K.
Lower P-input levels in organic than conventional farming can decrease soil total and available P, which can potentially be resupplied from soil organic P. We studied the effect of 30 y of conventional and organic farming on soil P forms, focussing especially on organic P. Soil samples (0–20 cm) were taken in a field experiment with a nonfertilized control, two organic systems receiving P inputs as animal manure, and two conventional systems receiving only mineral P or mineral P and manure. Soils were analyzed for total, inorganic, organic, and microbial P, by sequential P fractionation and by enzyme additions to alkaline soil extracts. Samples taken prior to starting the experiment were also analyzed. Average annual P balances ranged from –20 to +5 kg...

Leaf stripe resistance of spring barley cultivars
Provedor de dados: 21
Autores: Pinnschmidt, Hans O.; Nielsen, Bent J.
Results of six years of screening trials clearly indicate that effective resistance against barley leaf stripe is available, also in modern cultivars. Among the spring barley cultivars that are currently most widely grown in Denmark, Cabaret, Troon, Sebastian, Justina and Brazil appear most resistant, but only Brazil combines a favourable resistance performance (= low mean and standard deviation of environment-adjusted leaf stripe incidence) with a high number of observations (= years of testing). However, the cultivars appearing most resistant over the years are relatively old ones such as Vada, Alabama, Odin and particularly Scarlett, which has been resistant in all years in which it was tested. Amongst the new cultivars, Marigold, Native and SW Immer...

Review: Pig excretory behaviour
Provedor de dados: 21
Autores: Andersen, Heidi Mai-Lis; Kongsted, A.G.; Jakobsen, M.
Finding ways to motivate pigs to excrete in dedicated areas is of major importance for the environment, human health and animal welfare. This review investigates pigs’ excretory behaviour and the relation to the rearing and housing environment in addition to identifying important knowledge gaps in this respect. Eliminating away from the nest/lying area appears to be innate but evolves over time. Postpartum, piglets urinate and defecate close to the nest, indicating that it is difficult to influence piglets’ choice of elimination area, as this is influenced by the sow’s choice of nest area. At increased age piglets begin to excrete further away from the nest, which is probably related to the fact that piglets start to spend more time away from it. There is...

Er der sammenfald i sædskiftesygdomme blandt arter af frøbælgplanter
Provedor de dados: 21
Autores: Jensen, Birgit.
I et lupintræt areal, hvor der tidligere er observeret alvorlige Fusarium-symptomer i lupin, blev  der udsaaet fem sorter af henholdsvis ært, hestebønne og lupin. I såvel lupin som hestebønne blev der konstateret udbredte symptomer paa rodbrand og visnesyge, mens ærterne var symptomfri. Det tyder på, at specifikke Fusarium patogener fra lupin kan inficere rødder af hestebønne, men ikke ærterødder. De samme fem sorter af ært, hestbønne og lupin blev sået på et ærtetræt areal. Her blev kun ærterne angrebet, idet lupin og hestebønne var uden rodsymptomer. Ud fra dette ene års forsøg ser det således ud til, at ærtepatogenerne er meget specifikke for ært, mens lupin patogener kan gå på både lupin og hestebønne.

Multiple nutrient imbalances in eara-leaves of on-farm cultivated maize in Eastern Africa
Provedor de dados: 21
Autores: Høgh-Jensen, Henning; Kamalongo, D.; Myaka, F.A.; Adu-Gyamfi, J.J.
Maize is a major food crop in eastern and southern Africa and is often cultivated with insufficient supplies of nutrients. The current studies are aimed at diagnosing any potential nutrient limitation in maize under farmers’ conditions using the nutrient content in ear leaf tissue at tasseling stage. The majority of the maize crops were considered below the critical nitrogen (N) content in the ear leaves with mean N content of 1.84%. Phosphorus (P), B and Cu content appeared critically low at three of the four sites. Unique fingerprinting by multivariate statistics was possible for each site when using the proportion of nutrients in the leaf tissue. The content of six macro elements (N, P, K, S, Mg, Ca) at the tasseling stage were found to be able to...

Laying hens are commonly not slaughtered and utilized for food purpose. Slaughtered hens may be hydrolyzed (e.g. at 50°C for 1-2 hours, with additions of enzymes)to produce soluble proteins and oils. Sediments after such hydrolysis are valuable fertilizers, whereas the oil and proteins are valuable food ingredients of high quality.

Non-thermal food processing technologies are becoming more important in the organic food sector because, beyond preserving the organic feature, they could offer organic products with additional benefits in terms of enhanced nutritional content and healthiness as well as better sensory properties that could satisfy the more complex demands of organic consumers. Berries have a well-known health benefits and show increasing market shares in European markets while dehydration can increase the food convenience in terms of extended shelf-life. This study investigates for the first time organic consumers' stated preferences, attitudes and individual differences for a non-thermal organic processing technology. Specifically, we investigated consumers' preferences...

EFFICIENCY OF PRODUCTION ON ARABLE LAND IN ORGANIC AND CONVENTIONAL FARMING
Provedor de dados: 21
Autores: Moudry, Jan (Jr.); Sramek, J.; Konvalina, P.; Moudry, J.; Kopta, D.
One of the most evident difference between conventional and organic farming is yield height. Differences predominantly depend on the crop species and the major drop in yield when organic farming comes in the period of conversion, lower variability feature low-input species. Combination of factors defines overall yield distinction between conventionally and organically grown crops. Even if the organic farming reaches lower yields, differences in costs and prices of products have very strong positive effect on it´s efficiency, which could be even higher when compared to conventional farming.

Kocheigenschaften und Geschmack von ökologisch und konventionell erzeugten Kartoffeln stimmen nicht immer überein. Auch im Lager ist die Entwicklung der Geschmackseigenschaften unterschiedlich: Manche Sorten bevorzugen Kühllager mit konstanten Temperaturen, andere ein Belüftungslager.  Um herauszufinden, wie sich der Geschmack während der Lagerung verändert, fanden in den letzten zwei Jahren in Westfalen-Lippe Testessen nach der Ernte, im Winter und im zeitigen Frühjahr statt. Sechs bis zwölf Tester verkosteten bis zu 18 Sorten. Getestet wurden Kartoffeln aus vorgekeimtem und nicht vorgekeimtem Pflanzgut. Fleischfarbe, Feuchte, Kochfestigkeit und Geschmack sowie der Gesamteindruck der Knolle wurden bewertet. Die Kartoffeln wurden teils in einem Kühllager...

The role of agroecology in sustainable intensification
Provedor de dados: 21
Autores: Pearce, Bruce; Lampkin, Nicolas; Leake, Alastair; Padel, Susanne.
This paper explores how agroecological approaches can contribute to sustainable intensification. There is an ongoing debate on how we can produce the required levels of food the world needs on existing farmland, while minimising environmental impacts. The ‘sustainable intensification’ concept has been proposed to reconcile these two objectives.  In parallel, there is a growing interest in how agroecological approaches can contribute to the world’s food security. We reviewed the evidence for a large range of agroecological practices and made a close comparison between conventional agricultural systems and integrated agriculture, organic farming and agroforestry, comparing on a range of factors.  Overall, the study found that agroecological approaches can...

Orchards, as intensive cropping systems, often have low diversity of plant species, which limits the promotion of natural enemies for pest control. The implementation of agri-environmental schemes, such as flower strips, could enhance biological control. We developed perennial, multifunctional flower strips with native plant species. In the second and third year after sowing, plant diversity and ground cover between flower strips (FS) in the drive alleys and the spontaneous orchard vegetation in control plots (Cont) were compared in 19 experimental blocks of eight organic apple orchards in six European countries. On average 73.7% of the sown plant species were established and plant diversity of FS was on average 43% higher than in Cont. Multivariate...

Low level impurities in imported wheat are a likely source of feral transgenic oilseed rape (Brassica napus L.) in Switzerland
Provedor de dados: 21
Autores: Schulze, Juerg; Brodmann, Peter; Oehen, Bernadette; Bagutti, Claudia.
In Switzerland, the cultivation of genetically modified (GM) oilseed rape (Brassica napus L.) and the use of its seeds for food and feed are not permitted. Nevertheless, the GM oilseed rape events GT73, MS8×RF3, MS8 and RF3 have recently been found in the Rhine port of Basel, Switzerland. The sources of GM oilseed rape seeds have been unknown. The main agricultural good being imported at the Rhine port of Basel is wheat and from 2010 to 2013, 19 % of all Swiss wheat imports originated from Canada. As over 90 % of all oilseed rape grown in Canada is GM, we hypothesised that imports of Canadian wheat may contain low level impurities of GM oilseed rape. Therefore, waste fraction samples gathered during the mechanical cleaning of Canadian wheat from two Swiss...

Provedor de dados: 21
Autores: Blakemore, R.J.
Organic farming supplies more food with less ecological cost than chemical agriculture.  Earthworm aspects of organic farming are twofold: ‘waste’ recycling through compost worms and soil enhancement from endemic field worms.  Bio-physico-chemical benefits from sustained earthworm activity accrue for biodiversity, soil organic matter (SOM = worm-worked humus) derived from carbon sequestration of atmospheric CO2 via photosynthesis/humification and nitrogen N2 fixation from microbes rather than synthetic Haber-Bosch urea, plus greatly improved infiltration and soil-water-storage.    Just as earthworm burrows filter all rainwater, all atmospheric carbon from leaf litter/roots is processed through their intestines in 12 yr cycles as they build topsoil....

Autores: Thoms, Carolin; Gattinger, Andreas; Jacob, Mascha; Thomas, Frank M.; Gleixner, Gerd.
We investigated the link between aboveground and belowground diversity in temperate deciduous forest ecosystems. To this end, we determined the effects of the tree species composition on the biomass and composition of the soil microbial community using phospholipid fatty acid (PLFA) profiles in the Hainich National Park, a deciduous mixed forest on loess over limestone in Central-Germany. We investigated the effects of the leaf litter composition on the microbial community, hypothesizing that distinctive leaf litter compositions increase signature PLFAs. In addition, we studied the impact of clay content, pH and nutrient status of the soil on the microbial community in different surface soil layers. Consequently, soil was sampled from depths of 0–5 cm,...

Autores: Sylla, Justine; Alsanius, Beatrix W.; Krüger, Erika; Reineke, Annette; Strohmeier, Stephan; Wohanka, Walter.
The increasing use of biological control agents (BCAs) against Botrytis cinerea in strawberry raises the question of whether there are any undesirable impacts of foliar applications of BCAs on nontarget microorganisms in the phyllosphere. Therefore, our objective was to investigate this issue within a field study. Strawberry plants were repeatedly sprayed with three BCAs—namely, RhizoVital 42 fl. (Bacillus amyloliquefaciens FZB42), Trianum-P (Trichoderma harzianum T22), and Naturalis (Beauveria bassiana ATCC 74040)—to suppress Botrytis cinerea infections. Microbial communities of differentially treated leaves were analyzed using plate counts and pyrosequencing and compared with the microbial community of nontreated leaves. Plate count results indicate that...

Variable effects of organic farming systems on ground beetle abundance and diversity
Provedor de dados: 21
Autores: Navntoft, S.; Thorup-Kristensen, K.; Eilenberg, J.; Kristensen, K.; Meyling, N.V.
Organic farming should support high levels of biodiversity and rely on biological pest control by natural enemies. Management of organic systems must comply with specific regulations, but within this frame management is not clearly defined. In experimental cabbage fields we studied ground beetle abundance and diversity in three different organic farming systems (O1, O2, and O3). All systems complied with regulations for organic production, but relied on either high (O1) or low (O2 and O3) external input of nutrients. The systems O2 and O3 also included green manures, and in O3 strips of green manure were left between crop rows. A conventional system was included as control. Only organic systems O2 and O3 showed benefits for ground beetles, but in different...

Following the plough: genetic evidence of population  expansions of Perdix perdix during early transition and late intensification of agriculture in Denmark and Western Europe
Provedor de dados: 21
Autores: Andersen, Liselotte Wesley; Jacobsen, Magnus; Kahlert, Johnny; Odgaard, Bent.
The analysis of the haplotype diversity represented by the  sequences of the control region in the mitochondria in Danish partridges identified signals of population expansion as was the case in other European grey partridges. Based on this genetic analysis of the Danish recent and historical grey partridges together with previously analysed grey partridges from Germany, Poland, Hungary, France and Italy, it is hypothesized that the timing of the Grey partridge population expansions up through western Europe and the following dispersal of the grey partridge from the last LGM refugium in the French Pyrenees might be explained by the origin and spread of agriculture through Europe i.e.  “following the plough”.

Certified organic agriculture stipulates a range of principles and standards, which govern farmer practices. The recent global expansion of organic agriculture has raised new challenges for organic agriculture, particularly whether management practices in organic farms are subject to the forces of conventionalisation. We studied changes in agroecological practices in certified organic farms in China,Brazil and Egypt. The study takes departure in the conventionalisation hypothesis and the analysis is framed using organic and agroecological principles. The study focuses on agroecological design principles, inherent to organic agriculture, of diversity in crop production, pest, disease and weed management, and soil fertility management.

Analysis of transition forms towards more ecologically-oriented farming: the case of organic farming and integrated crop protection
Provedor de dados: 21
Autores: LAMINE, C.; MEYNARD, J.-M.; PERROT, N.; BELLON, S.
Interdisciplinary approaches developed concerning the conversion to organic farming show that the types of conversion trajectories can be differentiated on the basis of the progression of crop protection changes within a larger framework where relationships to other “objects” are transformed – the soil, products, rotations, work organisation, marketing, social networks and knowledge acquisition. In the case of integrated plant production, the extent of changes depends on the degree of recomposition of agronomic practices. This transition implies major knowledge acquisition that relies on the support and contribution of advisors and on the group dynamics that develop within a group of farmers. Transitions towards integrated crop protection are, by their...

The objective of the study was to prevent the accumulation of high concentrations of mineral N in the soil during the drainage season by growing the presumably most effective catch crop, Italian ryegrass, undersown in barley as a green crop for silage on sandy soil. Further more, to examine the effect on two fields with different management of the grass-clover ley and therefore a different mineralization potential after ploughing. The green barley/Italian ryegrass treatment was compared with barley grown to maturity with and without an undersown conventional catch crop of perennial ryegrass.

Consumers buy organic food because they believe in the high quality of the product. Furthermore, the EU legal regulatory framework for organic food and farming defines high quality of the products as an important goal of production. A major challenge is the need to define food quality concepts andmethods for determination. A background is described which allows embedding of the quality definitions as well as evaluation methods into a conceptual framework connected to the vision and mission of organic agriculture and food production. Organic food quality is defined through specific aspects and criteria. For evaluation each criterion has to be described by indicators.

Hotspots of soil organic carbon storage revealed by laboratory hyperspectral imaging
Provedor de dados: 21
Autores: Hobley, Eleanor; Steffens, Markus; Bauke, Sara L.; Kögel-Knabner, Ingrid.
Subsoil organic carbon (OC) is generally lower in content and more heterogeneous than topsoil OC, rendering it difficult to detect significant differences in subsoil OC storage. We tested the application of laboratory hyperspectral imaging with a variety of machine learning approaches to predict OC distribution in undisturbed soil cores. Using a bias-corrected random forest we were able to reproduce the OC distribution in the soil cores with very good to excellent model goodness-of-fit, enabling us to map the spatial distribution of OC in the soil cores at very high resolution (~53 × 53 µm). Despite a large increase in variance and reduction in OC content with increasing depth, the high resolution of the images enabled statistically powerful analysis in...

Autores: Haas, Brechtje, de; Hoekstra, Nyncke; Schoot, Jan Rinze, van der; Visser, Eric J.W.; Kroon, Hans, de; Eekeren, N. van.
Grass-clover mixtures show many benefits for sustainable agriculture. In the Netherlands, organic farmers often work together in a so-called partner farm concept, with the aim to close nutrient cycles on a regional level. In this system, arable farms grow one-year grass-clover leys, as fodder for a livestock farm, in exchange for, e.g., manure. This practice could also be used in the transition of conventional farms towards a more circular regenerative and nature inclusive agriculture. In the current experiment we assessed the effect of a range of grass (Lolium perenne: Lp, Lolium multiflorum: Lm) and clover (Trifolium pratense: Tp and Trifolium repens: Tr) monocultures and mixtures on both below- and aboveground parameters in light of benefits for...

État des lieux de la collecte du blé biologique panifiable en France
Provedor de dados: 21
Autores: David, Christophe; Joud, Stéphane.
The collect sector of the organic winter wheat is in deep evolution following a widening of the outlets, on arrival of new operators resulting from the conventional sector and with a strong fluctuation in prices. The technological quality of organic wheat is predicted, in a restrictive way, from the protein content of the grains.  The requirements of food safety and traceability lead to an increase in controls, beyond the constraints of certification. The consolidation of the wheat-flour-bread chain in France induces (I) a reinforcement of the partnerships amongst the actors, (II) the definition of new criteria to assess the quality adapted to organic production but also, (III) new investments from collectors to guarantee technological quality and safety...

Effects on weeds of management in newly converted organic crop rotations in Denmark
Provedor de dados: 21
Autores: Rasmussen, I.A.; Askegaard, M.; Olesen, J.E.; Kristensen, K.
We investigated the effects on annual weeds of location, weed control, manure application and catch crops and their interactions in a crop rotation with cereals and pulses for grain during conversion to organic farming in order to better understand the combined effects of management. An experiment with a four-year crop rotation (spring barley/undersown ley, grass-clover, winter wheat, pea/barley) was carried out from 1997 to 2000 under organic conditions at three locations in Denmark with four treatments: with and without catch crop, and with and without manure. Mechanical weed control was reduced or absent in cereals or pulses with undersown catch crops or grass-clover. Manure application increased weed biomass, but not the proportion of total biomass...

Weed occurrence in Finnish coastal regions: a survey of organically cropped spring cereals
Provedor de dados: 21
Autores: Riesinger, Paul; Hyvönen, Terho.
Weed communities of organically cropped spring cereal stands in the southern and the northwestern coastal regions of Finland (= south and northwest, respectively) were compared with respect to number of species, frequency of occurrence, density and dry weight. Regional specialization of agricultural production along with differences in climate and soil properties were expected to generate differences in weed communities between south and northwest. Total and average numbers of species were higher in the south than in the northwest (33 vs. 26 and 15.6 vs. 10.0, respectively). Some rare species (e.g. Papaver dubium) were found in the south. Fumaria officinalis and Lamium spp. were found only in the south. The densities and dry weights of Lapsana communis,...

Autores: Ringuelet, Jorge Abel; Ocampo, Rafael; Henning, Cynthia; Padín, Susana; Urrutia, María Inés; Dal Bello, Gustavo.
Tribolium castaneum (Coleoptera: Tenebrionidae) es un insecto plaga de granos, muy destructivo en la etapa de almacenamiento y altamente resistente a los fitosanitarios sintéticos. Por esta razón su control químico se realiza con altas concentraciones de insecticidas que aumentan la contaminación ambiental y los peligros para la salud humana. Las tendências actuales en el manejo integrado de plagas se orientan hacia el uso de plaguicidas biológicos o biopesticidas como los extractos vegetales, que no generan resistencia y son de baja toxicidad. En ese sentido, el objetivo del presente trabajo fue estudiar la actividad repelente e insecticida del aceite esencial de Lippia alba (Verbenaceae) quimiotipo carvona-limoneno sobre adultos de T. castaneum, en...

Comparing risk perceptions and risk management in organic and conventional dairy farming: empirical results from Norway
Provedor de dados: 21
Autores: Lien, Gudbrand; Flaten, Ola; Koesling, Matthias; Valle, Paul Steinar; Ebbesvik, Martha.
This study was conducted to explore organic and conventional dairy farmers’ perceptions of risk and risk management, and to examine relationships between farm and farmer characteristics, risk perceptions, and strategies. The data originate from a survey of conventional (n=363) and organic (n=162) dairy farmers in Norway. Organic farmers had the least risk averse perceptions. Institutional and production risks were perceived as primary sources of risk, with farm support payments at the top. Compared to their conventional colleagues, organic farmers gave more weight to institutional factors related to their production systems. Conventional farmers were more concerned about costs of purchased inputs and animal welfare policy. Organic and conventional farmers’...

Autores: Vangdal, E; Picchi, V; Fibiani, M; Lo Scalzo, Roberto.
Plums contain high levels of hydroxycinnamates (neo-chlorogenic acid, Neo-CGA), anthocyanins (ATH) and ascorbic acid. The drying process influences their phytochemical content and plum cultivars are known to have different phytochemical retention after drying, but little data exists regarding to possible differences between conventional (CONV) and organic (ORG) plums. The aim of this study was to evaluate the phytochemical content in three different CONV and ORG plum cultivars (Jubileum, Reeves and Victoria) after freeze drying (FD), conventional oven drying (OD) and solar drying (SD).    The three cultivars responded differently to the methods of drying. Notably, Jubileum decreased its ATH mostly when subjected to OD while its Neo-CGA content was mostly...

Organic Feed: A Bottleneck for the Development of the Livestock Sector and Its Transition to Sustainability?
Provedor de dados: 21
Autores: Escribano, Alfredo J.
Abstract: There is a current need to increase global livestock production in line with consumers’ preferences for more sustainable and ‘natural’ products. Organic farming is considered among the potential production systems and market strategies that could be employed to cope with this change. Animal nutrition is key, as it greatly influences feed efficiency, animal health, and sustainability. Under situations where animal health care is technically more challenging, due to limitations in the use of veterinary drugs (such as in organic farming), the importance of feed is even higher. However, the there is a lack of commercially available permitted feed ingredients and the range of feed additives on the market is limited. This is partially due to the fact...

Consumers’ evaluation of imported organic food products: The role of geographical distance (only abstract - complete manuscript will follow, when published)
Provedor de dados: 21
Autores: Pedersen, Susanne; Aschemann-Witzel, Jessica; Thøgersen, John.
Abstract   Country-of-origin (COO) effects and consumer evaluation of organic food products are rarely studied as a whole. Thus, how consumers evaluate imported organic products is under-researched. The aim of this study was therefore to investigate organic consumers’ preferences for imported organic food products from different origins and the underlying reasons for these preferences, including how COO preferences depend on the consumers’ geographical distance to the COO. We applied a multi-method approach which consisted of in-store interviews (N = 255) and focus groups (six, N = 38) with organic consumers in three German cities located in the north (Hamburg, close to Denmark), west (Münster, close to The Netherlands) and south (Munich, close to...

Survival of the biocontrol agents Coniothyrium minitans and Bacillus subtilis MBI 600 into pasteurised, sterilised and non-sterile soils
Provedor de dados: 21
Autores: Bennett, Amanda J.; Leifert, Carlo; Whipps, John M.
The biocontrol agents Coniothyrium minitans and Bacillus subtilis MBI 600 were added separately to three soil types that had been either sterilised, pasteurised or left non-sterile. Applied as a conidial suspension of 1 X 10(6) cfu g(-1) soil, C. minitans showed good survival in all sterilised, pasteurised and non-sterile soils, remaining at the numerical level at which it was applied for the duration of the 30 d experiment. Applied at a lower rate of 1 X 10(3) cfu g(-1) Soil, C Minitans proliferated in sterilised soil to numbers slightly over 1 X 10(6) cfu g(-1) Soil, whereas no increase was seen in pasteurised or non-sterile soils from this lower application rate. However, although C. minitans was not easily recovered on plates from non-sterile soil, it...

Farming Differentiation in the Rural-urban Interface of the Middle Mountains, Nepal: Application of Analytic Hierarchy Process (AHP)Modeling
Provedor de dados: 21
Autores: Bhatta, G.D.; Doppler, W.
This article investigates the dominant factors of farming  differentiation in the rural-urban interface of the densely   populated Kathmandu Valley, using the Analytic Hierarchy Process (AHP) modeling. The rural-urban interface in the Kathmandu Valley is an important vegetable production pocket which supplies a large amount of the vegetables in the city core. While subsistence farming in the rural area is characterized by a system which integrates livestock and forestry with agriculture, the intensification in the urban fringe is characterized by triple crop rotations and market-oriented intensive vegetable production. Seven factors which were supposed to cause farming variation in the interface were incorporated in the AHP framework and then subjected to...

Bio-fortification and isotopic labelling of Se metabolites in onions and carrots following foliar application of Se and 77Se
Provedor de dados: 21
Autores: Kapolna, Emese; Laursen, Kristian Holst; Husted, Søren; Larsen, Erik H.
The aims were to bio-fortify onions by foliar application of selenium (Se) and to intrinsically label bioactive Se-metabolites in onion and carrot by enriched, stable77Se for use in human physiological studies. Onion bulbs and leaves were enriched in Se by repeated foliar spraying of 10 or 100 μg Se mL-1 solutions of sodium selenite (Se(IV)) or sodium selenate (Se(VI)). ICP-MS analysis of onion leaves and bulbs showed that the Se concentration was enhanced by up to a factor of approximately 50 and 200 in bulbs and leaves, respectively. HPLC-ICP-MS analysis of proteolytic plant extracts showed that foliar application of Se(IV) gave rise to bio-synthesis of a higher fraction of the desired organic Se species and was better tolerated by the plants than...

Farm- and product-level biodiversity assessment of conventional and organic dairy production in Austria
Provedor de dados: 21
Autores: Schader, C.; Drapela, T.; Markut, T.; Meier, M. S.; Lindenthal, T.; Hörtenhuber, S.; Pfiffner, L.
The novel method developed for this study evaluates the impact of farming practices on farmland biodiversity, allowing for the assessment of the biodiversity potential of dairy farms at farm and product levels. We linked farming practices as pressure indicators to the species number and abundance of 11 indicator species groups (ISGs), evaluated semi-quantitatively by expert judgements. We calculated biodiversity potential based on food–web relationships between the ISGs, using Monte Carlo simulations for the analysis of uncertainty of expert assessments. We applied the assessment model to 8925 dairy farms from seven different Austrian regions, using official statistical data sets at farm level and interviews with farmers and experts. The results show that...

Our review concludes that organic standards need to account for a broader set of criteria in order to retain claims to ‘sustainability’. Measurements of the ecological, economic and social outcomes from over 96 kiwifruit, sheep/beef and dairy farms in New Zealand between 2004 and 2012 by The Agricultural Research Group on Sustainability (ARGOS) project showed some enhanced ecosystem services from organic agriculture that will assist a “land-sharing” approach for sustainable land management. However, the efficiency of provisioning services is reduced in organic  systems and this potentially undermines a “land-sparing” strategy to secure food security and ecosystem services. Other aspects of the farm operation that are not considered in the organic standards...

Reduction of ammonia emission by shallow slurry injection: Injection efficiency and additional energy demand
Provedor de dados: 21
Autores: Hansen, Martin N.; Sommer, Sven G.; Madsen, Niels P.
Ammonia (NH3) emission from livestock production causes undesirable environmental effects and a loss of plant available nitrogen. Much atmospheric NH3 is lost from livestock manure applied in the field. The NH3 emission may be reduced by slurry injection, but slurry injection in general, and especially on grassland, increases the energy demand and places heavy demands on the slurry injection techniques used. The reduction in NH3 emission, injection efficiency and energy demand of six different shallow slurry-injection techniques was examined. The NH3 emission from cattle slurry applied to grassland was reduced by all the injectors tested in the study, but there were major differences in the NH3 reduction potential of the different types of injectors....

Autores: Eriksen, J.; Hermansen, J.E.; Strudsholm, K.; Kristensen, K.
Nutrient load and distribution on pasture were investigated with fattening pigs that: 1) spend a proportion of or their entire life on pasture, 2) were fed either restrictively or ad libitum, and 3) were weaned at different times of the year. The N and P retention in pigs decreased the longer they were kept on pasture. The contents of soil inorganic N and exchangeable K were significantly raised compared to the soil outside the enclosures but with no differences between treatments. Pig grazing did not affect extractable soil P. Regular moving of huts, feeding and water troughs was effective in ensuring that nutrients were more evenly distributed on the paddocks. Grass cover, as determined by spectral reflectance, was not related to the experimental...

Studies on the attractional effect of root exudates on hyphal growth of an arbuscular mycorrhizal fungus in a soil compartment-membrane system
Provedor de dados: 21
Autores: Vierheilig, H.; Alt-Hug, M.; Engel-Streitwolf, R.; Mäder, P.; Wiemken, A.
The effects of tomato and bean rhizospheres on hyphal spreading of the arbuscular mycorrhizal (AM) fungus Glomus mosseae were studied using a soil compartment system in combination with hydrophobic polytetrafluorethylene (PTFE) membranes. Both the nylon screen and the PTFE membrane were freely permeable to hyphae but not to roots. Furthermore, the hydrophobic PTFE membrane seemed to be a barrier to the flux of soil solutions containing root exudates. The results show that water soluble exudates of tomato and bean roots greatly stimulate hyphal growth in the soil compartment system used. Moreover, water soluble root exudates of bean exert a clear attractional effect on AM hyphal growth.

Interest Group Capacities and Infant Industry Development: State-sponsored Growth in Organic Farming
Provedor de dados: 21
Autores: Halpin, Darren; Daugbjerg, Carsten; Yonatan Schvartzman , Yonatan.
Both interest group and public policy scholars accept that groups are important to policy formulation and implementation because they hold valuable capacities. However, the literature has not dwelt upon whether, and how, groups develop capacities. In this article we examine the question of group capacity development by focussing on the adaption of specific groups to evolving policy contexts. Taking the example of organic farm policy we look at the impact divergent policy strategies aimed at growing this infant industry sector have had on the way related industry groups have evolved in four countries. This comparative study supports our argument that policy strategy is one key force in shaping the capacities that groups develop over time.

Innovations in low input and organic dairy supply chains - What is acceptable in Europe?
Provedor de dados: 21
Autores: Nicholas, Phillipa; Mandolesi, Serena; Naspetti, Simona; Zanoli, Raffaele.
The growth in organic and low-input farming practices is driven by both market demand for high quality, safe food, and European Union policy support, and these types of farming practices are considered in European Union policies for sustainable production, food quality, healthy life, and rural development. However, many constraints to the development of low-input and organic dairy farming supply chains have been identified, including economic, political, and technical constraints. In order for these types of supply chains to develop and provide further benefits to society, innovations are required to improve their sustainability. However, an innovation will only be taken up and result in desirable change if the whole supply chain accepts the innovation. In...

Autores: Ankamah-Yeboah, Isaac; Nielsen, Max; Nielsen, Rasmus.
The report compares ecolabeled seafood premiums observed in the market with consumers’ stated willingness to pay premiums. Also ecolabeled premiums in the agricultural sector were examined. The next issue addressed was the sensitivity of changes in the price and premiums of ecolabeled seafood. Empirical findings showed that all things being equal, consumers stated willingness to pay reflects in their actual market behavior though they may pay less than stated. Premiums observed in the aquaculture (24-38%) appear to be generally higher than the fisheries (10-13%). Stated premiums for environmentally sound seafood production however ranged from 15-50%. In the agricultural sector, revealed premiums mostly seem to lie in range of 10-50% with few extremes and...

Shaping professional identity for sustainability. Evidence in Finnish public catering
Provedor de dados: 21
Autores: Mikkola, Minna.
Catering for sustainability is often presented as a legitimate perspective for caterers to promote more  equitable economic development locally and across distances through food procurement, integrated  with environmental protection and concern for thewelfare of customers and staff. Caterers are thus seen  as agents responsible for sustainable food systems within their reach. This paper explores how public  caterers use their position and productive intelligence in promoting a sustainable food system within the  power field of their contextual networks. This article crystallises this ‘agency for sustainability’ as  professional identity for sustainability, the shaping of which is analysed in Finnish public catering.

Field efficacy of entomopathogenic fungi to control Rhagoletis cerasi.  Two myco-insecticides, Naturalis-L (Beauveria bassiana) and PreFeRal®WG (Paecilomyces fumosoroseus), were applied against adult R. cerasi Loew (Diptera: Tephritidae) in two orchards in north-western Switzerland in summer 2006. Both products were able to cause mycosis on adult flies under field conditions. However, only Naturalis-L significantly reduced the number of damaged fruits (efficacy: 69-74%), whereas damaged fruits were not significantly reduced with PreFeRal (efficacy: 27%). For B. bassiana living fungal propagules were still detectable seven days after application while the fungal propagules of P. fumosoroseus remained only three days. A control of R. cerasi with...

Autores: Fossing, C.; Vaarst, M.; Wemelsfelder, F.; Thamsborg, S.M.
The aim of this study was to test the application of a novel statistical method, Free Choice. Profiling (FCP), for evaluation of cattle health. Participants were two groups of veterinarians: a group with biomedical background (n=7) and a group, who practiced homeopathy (n=8). Examined animals were 10 dairy cows. Using FCP methodology participants evaluated behavior in relation to health by watching video sequences of the cows, and evaluated health status by conducting clinical examinations. Data was analyzed with Generalized Procrustes Analysis, both separately for the 2 groups and for the merged group. Significant agreement was found between participants for all analyses (p&lt;0.001), particularly regarding behavior (between 70-80%). Semantic...

Economics Evaluation of Apple Production Systems
Provedor de dados: 21
Autores: Bravin, Esther; Mencarelli Hofmann, Daniel; Kockerols, Katharina; Weibel, Franco.
With economic indicators from the full cost account and the cash flow statement it is possible to identify the return-risk profile for the organic and the integrated apple production in Switzerland. The full cost account and the cash-flow time line are composed with the managerial-economical software-tool Arbokost. Due to higher (more than 100%) prices in the organic production, growing organic satisfies more return-oriented producers than growing certified integrated. However, the higher return in the organic production is bound to a higher risk. With the certified integrated production (IFP), return and risk are lower.  ‘Arbokost’ is an economic farm management software tool for fruit growers. Per orchard it reflects a full cost account, the cash flows...

A number of advanced satellite positioning based systems  for agricultural machines have been developed and are commercial available for aiding and supporting navigation  efforts up to full auto-steering. Furthermore, in terms of  the route planning for agricultural field operations, advanced methods based on combinatorial optimisation of fieldwork patterns have recently been introduced. In order to apply and implement these methods in the high-level control system of agricultural machines, an appropriate  representation of the field as a geometrical entity made up of discrete geometric primitives, such as points, lines, and polygons is needed. Preferably, such a representation must be generated in real-time providing the input to the whole accuracy range...

Autores: Moudry, Jan (Jr.); Hartl, Wilfried; Cudlinova, Eva; Moudry, Jan; Konvalina, Petr; Sramek, Jan.
As a very particular agricultural system organic farming encounters many problems. Some of these problems are common to several countries where organic farming is applied. On that ground it might be useful to compare condition and levels of organic farming in more countries, find its common problems and thanks to experience transmission try to eliminate some of these problems preventively.  Mutual comparison of organic farming in the Czech Republic with organic farming in Austria and actual conditions assessment provide to determine main problems of organic farming in both countries.  Within the framework of analysis of organic farming several general problems of organic farming in both countries were defined, e. g. lower yields and higher costs per...

Public perceptions of rural landscapes in land consolidation procedures in Poland
Provedor de dados: 21
Autores: Kupidura, Adrianna; Łuczewski, Michael; Home, Robert; Kupidura, Przemysław.
A high level of fragmentation of farms exists in many parts of Poland, which leads to inefficiency in farm management and a range of logistical problems. Land consolidation is a process that reverses fragmentation by enabling an exchange of plots of equivalent value between participants. The primary aim of land consolidation is to improve spatial and economic conditions for farming by decreasing the number of separate plots that belong to a given farm, adjusting the shape of plots to enable mechanized cultivation of soil, and decreasing the distance between dwellings and cultivated plots. Contemporary consolidation works, performed in compliance with the principles of sustainable development, enable creation of legaland spatial conditions that allow the...

Tillage in the growing season is ineffective as a tool of increased soil N mineralization
Provedor de dados: 21
Autores: Thomsen, Ingrid Kaag; Sørensen, Peter.
Soil tillage serves a number of purposes such as control of weeds, incorporation of crop residues and manures, and maintenance or improvement of soil mechanical properties, including seedbed preparations. As a side-effect, soil tillage may affect turnover of organic matter (OM) by changing the particle size and spatial distribution of crop and manure residues in soil and by increasing the intimacy of residue/soil contacts. By breaking soil structural elements, tillage may contribute further to N mineralization by exposing physically protected organic matter to microbial turnover. Therefore, adjusting the time, intensity and frequency of soil tillage operations may enable optimization of synchrony, defined as the matching through time of N availability and...

A sustainability assessment of organic and conventional beef cattle farms in agroforestry systems: the case of the dehesa rangelands
Provedor de dados: 21
Autores: Escribano, A.J.; Gaspar, P.; Mesias, F.J.; Pulido, A.F.; Escribano, M.
Pasture-based livestock systems are a key element for the maintenance of the dehesa ecosystem. However, adaptative changes (mainly intensification) are reducing their sustainability. As a consequence, sustainable livestock systems must be found and implemented. Due to this, this work assesses the sustainability of 63 beef cattle farms (including organic and conventional ones) with two aims: (i) to identify the most sustainable systems and; (ii) to establish management measures in order to increase farms sustainability. For this purpose, a methodological adaptation of the MESMIS Framework was applied. A cluster analysis allowed us to identify three farms typologies. Typology 1 (organic farms) had the highest scores for the sustainability index (66.75%) and...

Framework in agriculture on the farm level
Provedor de dados: 21
Autores: Haas, G.; Wetterich, F.; Geier, U.
Life Cycle Assessment (LCA) is a method that can be used to assess the environmental impact of agriculture, but impact categories and the functional unit of classical LCA’s must be adapted to the specific agricultural production process. Serving as an example, the framework of a LCA of 18 grassland dairy farms covering three farming intensity levels and carried out in the Allgäu region in southern Germany is presented. By focussing on the chosen impact categories and the respective, suitable functional units, the specific needs and backgrounds of conducting an agricultural LCA are discussed in general.

Rudolf Steiner wrote that “The nearness of the Koberwitz estate to Breslau made it possible to unite the agricultural course with other anthroposophical work”. Each day, after the Agriculture Course was presented at the Koberwitz chateau of Count Keyserlingk, Steiner commuted to Breslau (now Wrocław, Poland) and back. Most attendees of the Agriculture Course stayed at Breslau and commuted daily in the opposite direction. Steiner’s evening karma lectures were delivered in the lecture hall on the top floor of the Viktoria School (now Liceum Ogólnokształçace Nr 1). Wrocław is now a vibrant, prosperous, Polish city, having been forfeited by Germany following WWII. Wrocław is the European Capital of Culture (Europejska stolica kultury) for 2016.

Provedor de dados: 21
Autores: Kratochvil, R.; Kaltenecker, M.; Freyer, B.
A sustainable agricultural and food system is characterized by two qualities: availability of high-quality, healthy food along with the best possible preservation of natural resources. Organic farming is discussed as a solution model for the complementary achievement of both aims.   Taking the region Mostviertel-Eisenwurzen (A) as a case study, the present investigation examines the regional self-reliance in food production by means of three scenarios. In the basic scenario, the current land use of the region is set against the present-day food demand of the local population. The organic scenario assumes that the farming method of the region adheres 100% to the guidelines of organic farming. The food produced is set against the current food demand, as in...

Autores: Arnault, Ingrid; Lombarkia, Nadia; Ondet, Sophie-Joy; ROMET, L.; Brahim, Imene; Meradi, Rahma; Auger, J; Derridj, Sylvie.
Abstract  BACKGROUND    The effects of foliar applications of microdoses of sucrose to reduce the damage by the codling moth have been reported from nine trials carried in France and Algeria from 2009 to 2014. The activity of sucrose alone was assessed by comparison with an untreated control and some treatments with the Cydia pomonella granulovirus or a chemical insecticide. The addition of sucrose to these different treatments was also investigated.  RESULTS    The application of sucrose at 0.01% reduced the means of infested fruits with a value of Abbott's efficacy of 41.0 ± 10.0%. This involved the induction of resistance by antixenosis to insect egg laying. Indeed, it seems that acceptance of egg laying on leaves treated with sucrose was reduced. The...

Autores: Dabbert, Stephan; Häring, Anna.
The rapid development of organic farming over the last decade is partly due to increased consideration of organic farming in policy measures. Examining this view, this article briefly discusses the current state and development of the organic farming sector and three lines of justification for policy support for organic farming: organic farming supplies public goods; the organic farming sector can be defined as an infant industry; and organic farming should be supported for risk precaution. Then, based on the observation that policy makers consider organic farming support justified, an integrated approach to organic farming policy is outlined.

The objective of this study was to estimate herbage intake in Danish Friesian and Danish Jersey steers at an age of 8-9 months on ryegrass / white clover pasture. The steers were turned out on pasture in late April and herbage intake was estimated in June in steers of a mean live weight (± S.D.) of 264 ± 14 kg and 185 ± 25 kg for Danish Friesian and Danish Jersey respectively. Faeces and herbage samples were analysed for alkanes to estimate herbage dry matter intake, dry matter digestibility (DMD) and botanical composition of intake. The weight gains at the time of herbage intake estimation in June (kg/day) were 1.142 ± 265 kg/day and 0.927 ± 168 kg/day for Danish Friesian and Danish Jersey respectively. Daily herbage intake (kg dry matter (DM)) estimated...

In vivo effect of dried chicory root (Cichorium intybus L.) on xenobiotica metabolising cytochrome P450 enzymes in porcine liver
Provedor de dados: 21
Autores: Rasmussen, Martin Krøyer; Zamaratskaia, Galia; Ekstrand, Bo.
Cytochrome P450 (CYP) enzymes are widely studied for their involvement in metabolism of drugs and endogenous compounds. In porcine liver, CYP1A2,2Aand 2E1 are important for the metabolism of skatole.Feeding chicory roots to pigs is known to decrease the skatole concentration in plasma and fat. In the present study we investigated the effect of chicory on CYP mRNA and protein expression, as well as their activity. Male pigs were feed dried chicory root for 16 days before liver samples were collected. By the use of RT-PCR and Western blotting we showed that the mRNA and protein expression of CYP1A2 and 2A were increased in chicory fed pigs. The mRNA expression of CYP2E1 was increased, while there was no effect on protein expression. Activity of CYP1A2 and 2A...

Tillage System Comparison in Organic Farming: Effects on N  Mineralization, Soil Microbial Biomass, and Yield
Provedor de dados: 21
Autores: Grosse, Meike; Haase, Thorsten; Heß, Jürgen.
The nitrogen supply can be a yield-limiting factor in organic farming, especially when reduced tillage is applied. An organic field experiment was conducted from 2007 to 2013 to analyse the potential of the nitrogen supply through the efficient use of green manure crops in different tillage systems. Three farming systems were compared: a stubble cleaner system (SC) and a plough system (PL), both in a cereal-based crop rotation, and another plough system in a crop rotation that included alfalfa grass ley (PLALF). In the fifth year of the experiment, the experimental design was extended into a split plot design, and seven green manure treatments (Lolium perenne, Phacelia tanacetifolia, Sinapis alba, a mixture of Sinapis alba and Trifolium resupinatum,...

This study investigated the influence of the rainbow trout (Oncorhynchus mykiss) commensal intestinal microbiota in connection to an experimental Yersina ruckeri infection, the causative agent of enteric redmouth disease. One marine and one plant diet was administered to two different groups of rainbow trout. The plant-based diet gave rise to an intestinal microbiota dominated by the genera Streptococcus, Leuconostoc and Weissella from phylum Firmicutes whereas phylum Proteobacteria/Bacteroidetes/Actinobacteria dominated the community in the marine fed fish. In connection to the Y. ruckeri bath challenge there was no effect of the diet type on the cumulative survival, but the number of Y. ruckeri positive fish as measured by plate count and the number of...

Macropore flow as influenced by grazing, fertilization and duration of the leys in organic dairy rotations
Provedor de dados: 21
Autores: Lamandé, M.; Eriksen, J.; Krogh, P.H.; Jacobsen, O.H.
Managed grasslands are characterized by rotations of leys and arable phases. Soil structure is inherited from the last tillage operations (ploughing, harrowing) and evolves during the leys because of climate, earthworms and roots activity, fertilisation, cutting operations or cattle trampling. We tested the effects of the duration of the leys, cattle trampling, and fertilisation on the infiltration of water in the soil profile in managed grasslands. The experiment was situated within the dairy crop rotation on loamy sand at the Foulum experimental farm (Denmark). Irrigation experiments were performed in the 1st and the 3rd year of pasture, with or without slurry application or grazing, and in winter rye. Each plot was irrigated during an hour with 18.5 mm...

Autores: Jacobi, Johanna; Andres, Christian; Schneider, Monika; Pillco, Maria; Calizaya, Patricia; Rist, Stephan.
This study compares aboveground and belowground carbon stocks and tree diversity in different cocoa cultivation systems in Bolivia: monoculture, simple agroforestry, and successional agroforestry, as well as fallow as a control. Since diversified, agroforestry-based cultivation systems are often considered important for sustainable development, we also evaluated the links between carbon stocks and tree diversity, as well as the role of organic certification in transitioning from monoculture to agroforestry. Biomass, tree diversity, and soil physiochemical parameters were sampled in 15 plots measuring 48 × 48 m. Semi-structured interviews with 52 cocoa farmers were used to evaluate the role of organic certification and farmers’ organizations (e.g., cocoa...

Estimated N leaching losses for organic and conventional farming in Denmark
Provedor de dados: 21
Autores: Knudsen, Marie Trydeman; Kristensen, Ib Sillebak; Berntsen, Jørgen; Petersen, Bjørn Molt; Kristensen, Erik Steen.
The impact of organic compared to conventional farming practices on N leaching loss was studied for Danish mixed dairy and arable farms using an N balance approach based on representative data. On mixed dairy farms a simple N balance method was used to estimate N surplus and N leaching loss. On arable farms the simple N balance method was unreliable due to changes in the soil N pool. Consequently, the FASSET simulation model was used to estimate N surplus, N leaching loss and the changes in the soil N pool.   The study found a lower N leaching loss from organic than conventional mixed dairy farms, primarily due to lower N inputs. On organic arable farms the soil N pool was increasing over years but the N leaching loss was comparable to conventional arable...

An Analysis of Organic Agriculture in Turkey: The Current Situation and Basic Constraints
Provedor de dados: 21
Autores: Özbilge, Zeynep.
This article gives information about the current situation of Turkish organic agriculture, especially by comparing the official recognition for organic farming in the European Union with that of Turkey and summarizes the existing constraints. The analysis indicates that the further development of Turkish organic agriculture depends upon the development of the domestic organic market and Turkey has to fulfil a number of conditions to provide it. It is needed that the Turkish state both encourages organic production for the domestic market and supports organic agriculture by all means.

Video on mobile phones as an effective way to promote sustainable practices by facilitating innovation uptake in Mali
Provedor de dados: 21
Autores: Sousa, Fernando; Nicolay, Gian; Home, Robert.
A challenge for researchers and other developers of new technologies in agriculture is to find ways of communicating their results and recommendations. This challenge is particularly acute in regions in which farmers have limited access to education and where illiteracy is widespread, such as in the rural areas of Mali. One approach that shows potential, yet remains largely unused by extension services, is the dissemination of educational videos on mobile phones with video and Bluetooth technology (3G mobile phones). It has been shown that the conditions are suitable for this approach to be used in Mali, with 3G mobile phones widely available in the region but there is little empirical evidence of its acceptance and potential impact.

Tolerance of four spring barley (Hordeum vulgare L.) varieties to weed harrowing
Provedor de dados: 21
Autores: Hansen, Preben Klarskov; Rasmussen, Ilse A.; Holst, Niels; Andreasen, Christian.
We investigated the tolerance to weed harrowing of four spring barley varieties and examined the possible interactions between varietal weed suppressive ability and two nutrient levels. Tolerance was defined as the combined effect of crop resistance (ability to resist soil covering) and crop recovery (the ability to recover in terms of yield). The weed harrowing strategy was a combination of one pre- and one post-emergence weed harrowing. In terms of yield, the four varieties responded significantly differently to weed harrowing and the response depended on nutrient level. At the lower nutrient level, weed harrowing caused an increase in yield of 4.4 hkg ha-1 for a strong competitor (cv. Otira), while there was no effect on yield at the higher nutrient...

Timing of post-emergence weed harrowing
Provedor de dados: 21
Autores: Rasmussen, Jesper; Mathiasen, Helle; Bibby, Bo Martin.
The timing of post-emergence weed harrowing was evaluated  for two years in spring barley with crop-weed selectivity and crop recovery as the key parameters measured. selectivity describes the relationship between weed control and crop soil cover immediately after harrowing, with crop soil cover as the percentage of the crop that has been covered by soil due to harrowing. Crop recovery describes the relationship between crop yield loss and crop soil cover in the absence of weeds. Neither selectivity nor crop recovery  was affected by timing within a period of two weeks in the early growth stages of spring barley. Selectivity was unaffected by year and 80% weed control was associated with crop soil cover in the range of 23–33%, for all combinations of year...

Demand for organic foods is partially driven by consumers' perceptions that they are more nutritious. However, scientific opinion is divided on whether there are significant nutritional differences between organic and non-organic foods, and two recent reviews have concluded that there are no differences. In the present study, we carried out meta-analyses based on 343 peer-reviewed publications that indicate statistically significant and meaningful differences in composition between organic and non-organic crops/crop-based foods. Most importantly, the concentrations of a range of antioxidants such as polyphenolics were found to be substantially higher in organic crops/crop-based foods, with those of phenolic acids, flavanones, stilbenes, flavones, flavonols...

The effect of barley-legume intercrop in an organic farming system on disease incidence was investigated. The legumes were lupin, faba bean and pea. Diseases were detected on pea and barley. On pea, only ascochyta blight (Ascochyta pisi) was observed. When either pea variety was intercropped with barley, the level of ascochyta blight was reduced. Net blotch (Pyrenophora teres), brown rust (Puccinia recondita) and powdery mildew (Blumeria graminis f. sp. hordei) (in order of incidence) were monitored on barley between flag leaf emergence and heading. The levels of all three diseases were reduced in every intercrop treatment compared to the barley monocrop. However, this reduction was only statistically significant in the pea treatments for net blotch.

Management of service crops for the provision of ecosystem services in vineyards: A review
Provedor de dados: 21
Autores: Garcia, Léo; Celette, Florian; Gary, Christian; Ripoche, Aude; Valdés-Gómez, Hector; Metay, Aurélie.
Service crops are crops grown with the aim of providing non-marketed ecosystem services, i.e. differing from food, fiber and fuel production. Vineyard soils face various agronomic issues such as poor organic carbon levels, erosion, fertility losses, and numerous studies have highlighted the ability of service crops to address these issues. In addition to their ability to increase soil organic matter and fertility, and reduce runoff and erosion processes, service crops provide a large variety of ecosystem services in vineyards such as weed control, pest and disease regulation, water supply, water purification, improvement of field trafficability and maintenance of soil biodiversity. However, associating service crops with grapevines may also generate...

Interest Group Capacities and Infant Industry Development: State-sponsored Growth in Organic Farming
Provedor de dados: 21
Autores: Halpin, Darren; Daugbjerg, Carsten; Yonatan Schvartzman , Yonatan.
Both interest group and public policy scholars accept that groups are important to policy formulation and implementation because they hold valuable capacities. However, the literature has not dwelt upon whether, and how, groups develop capacities. In this article we examine the question of group capacity development by focussing on the adaption of specific groups to evolving policy contexts. Taking the example of organic farm policy we look at the impact divergent policy strategies aimed at growing this infant industry sector have had on the way related industry groups have evolved in four countries. This comparative study supports our argument that policy strategy is one key force in shaping the capacities that groups develop over time.

Species richness and abundance of vascular plants and several groups of invertebrates (spiders, oribatid mites, diplopods, grasshoppers and bush crickets, ground beetles, butterflies and terrestrial gastropods) were recorded in three calcareous grasslands (Nenzlingen, Movelier and Vicques) in the northwestern Swiss Jura mountains. Species richness varied both between taxonomical groups and between sites (species richness ranges: 96-116 vascular plants, 60-66 spiders, 18 oribatid mites at each site, 1-7 diplopods, 10-16 grasshoppers and bush crickets, 19-21 ground beetles, 32-46 butterflies and 15-21 terrestrial gastropods). Species overlap (number of species that occured at all sites) was relatively large in terrestrial gastropods (59,1%), butterflies...

Catch Crops in Organic Farming Systems without Livestock Husbandry - Simulations with the DAISY model
Provedor de dados: 21
Autores: Müller, Torsten; Thorup-Kristensen, Kristian; Magid, Jakob; Jensen, Lars Stoumann; Hansen, Søren.
This paper presents simulations of the soil-plant-atmosphere model DAISY based on an organic crop rotation with incorporation of different catch crops following pea as a leguminous cash crop. Special emphasise was put on the simulation of N-mineralisation/-immobilisation and of soil microbial biomass N. The DAISY model was able to simulate soil mineral N and soil microbial biomass N after soil incorporation of catch crop plant residues to some extend. Several processes need further attention and may be integrated into the DAISY model: (1) soil tillage induced mobilisation of organic material including considerable amounts of organic N, (2) winter killing of sensitive plant species and varieties, (3) decomposition of plant residues at the soil surface as...

Succès finlandais pour le colza bio
Provedor de dados: 21
Autores: Hokkanen, H.; Menzler-Hokkanen, I.; Daniel, C.
En Finlande, la culture biologique du colza est importante depuis plus longtemps que chez nous. Après un démarrage difficile, les agriculteurs biologiques finlandais ont atteint une surface de près de 3000 hectares de colza. L’expérience finlandaise peut nous être précieuse surtout dans le domaine de la lutte contre le méligèthe et dans celui des sous-semis (semis de couverture).  La Finlande cultive en bio 2000 à 3000 hectares de colza d’été depuis près de 10 ans. L’huile de colza pressée à froid du pays ne se vend pas seulement dans les magasins bio, mais aussi dans la plupart des supermarchés. Cela n’empêche pas la demande de dépasser l’offre, et les huileries prennent de nouveaux producteurs sous contrat.

Members of the organic supply chain need high-quality data to make correct investment decisions, but data with sufficient depth and quality are not widely available in Europe. The quality of available data is a key concern for both data collectors and data users. The aim of this study is to identify whether the commonly used quality attributes (accuracy, coherence, comparability, timeliness, punctuality, accessibility, relevance), which have been developed from the perspective of data collectors, are also appropriate from the perspective of end users of organic market data. A further aim is to assess whether the data quality needs of end users are being met by the existing data. The results of two surveys carried out in Europe, one of data collectors and...

Pflanzenbauliche Strategien für die ökologische Erzeugung von Verarbeitungskartoffeln - 1. Teil: Kleegrasmanagement
Provedor de dados: 21
Autores: Krause, Tanja; Böhm, Herwart; Loges, Ralf; Haase, Norbert U.
Die Erzeugung von Verarbeitungskartoffeln im ökologischen Landbau hat im Gegensatz zu Speisekartoffeln bisher noch eine geringe Bedeutung. Denn ein großer Anteil der ökologisch erzeugten Kartoffeln wird für die Direktvermarktung angebaut, nur rund die Hälfte gehen in den Großhandel oder Industrie. In den letzten Jahren wurden ca. 3.000 bis 5.000 t Kartoffeln zu Chips und vor allen Dingen zu Pommes frites verarbeitet, was einer Anbaufläche von max. 200 ha entspricht. Im Zuge der Ausweitung des ökologischen Landbaus und gleichzeitig steigender Nachfrage der Verbraucher nach Convenience-Produkten wie Chips und Pommes frites könnte die Erzeugung von Verarbeitungskartoffeln den Landwirten neue Einkommensquellen bieten.

Turnover of organic matter in differently textured soils. I. Physical characteristics of structurally disturbed and intact soils
Provedor de dados: 21
Autores: Schjønning, P.; Thomsen, I.K.; Møberg, J.P.; de Jonge, H.; Kristensen, K.; B.T., Christensen.
Soil type effects on organic matter turnover are most often ascribed directly to differences in soil clay content. Since soil texture determines the physical characteristics of soil, aggregation and water holding capacity may be more relevant to address in the search for controls of organic matter turnover. Most studies of microbial processes in soils are based on structurally disturbed soil, where the abiotic conditions for the microbial activity may be quite different from those in intact soils. In this study, basic physical characteristics were determined for structurally disturbed and intact soil samples from differently textured soils. Bulk soil was retrieved from 0–20 cm depth at six locations along a textural gradient in an arable field on...

Increasingly, food consumption occurs in  out-of-home contexts, where organic food can also  have a role to play. Public food services may be  utilised to increase the sustainability of providing  nutrition. Although school meals may be well suited  to integrating organic food and sustainable nutrition  concepts, school food provision systems are very  different across Europe. This paper compares school  food provision systems and their utilisation of organic  food in Denmark, Finland, Germany, Italy and  Norway, discussing how various strategies and instruments  used for organic food procurement in school  meals may increase organic food consumption. Using  five analytical categories—(a) type of school food  service, (b) degree of public financing, (c)...

Life cycle modelling of environmental impacts of application of processed organic municipal solid waste on agricultural land (EASEWASTE)
Provedor de dados: 21
Autores: Hansen, Trine L.; Bhander, Gurbakhash S.; Christensen, Thomas H.; Bruun, Sander; Jensen, Lars S.
A model capable of quantifying the potential environmental impacts of agricultural application of composted or anaerobically digested source-separated organic municipal solid waste (MSW) is presented. In addition to the direct impacts, the model accounts for savings by avoiding the production and use of commercial fertilizers. The model is part of a larger model, Environmental Assessment of Solid Waste Systems and Technology (EASEWASTE), developed as a decisionsupport model, focusing on assessment of alternative waste management options. The environmental impacts of the land application of processed organic waste are quantified by emission coefficients referring to the composition of the processed waste and related to specific crop rotation as well as soil...

Autores: Schmid, Otto.
Im Hinblick auf die Richtlinien besteht heute ein doppeltes Dilemma: Zum einen geben immer öfter staatliche Stellen – anstatt engagierter Bio-Bauern – die Inhalte der Regeln vor. Einst suchte der ökologische Landbau die staatliche Anerkennung, nun wird sie von manchen Akteuren kritisch gesehen. Gewünscht werden hingegen Konzepte, die den Bauern wieder mehr Eigenverantwortung geben. Wie soll das geschehen? Zum anderen ist die Gesellschaft zwar bereit, den Bio-Landwirten ihre positiven gesellschaftlichen Leistungen zu bezahlen, allerdings sind diese in den Richtlinien nicht immer auf den ersten Blick erkenn- und messbar.

Production of tomatoes in the organic system is very important because these are not only the most vegetables widely consume (the second after potato) but also are classified as a functional food. Due to the high content in bioactive compounds, especially lycopene, tomatoes provide nutritional properties and also contribute to maintaining health. In this context, the aim of this study is to compare the nutritional quality parameters of two organic red tomato varieties, Coeur de Boeuf’ and ‘Cher Ami’ grew under controlled conditions in a hi-tech glass greenhouse. The quality parameters analyzed were the titratable acidity, total soluble solids, dry matter, carotenoid and lycopene content. The highest total soluble solid content, lycopene and carotenoid...

Zinc (Zn) deficiency in human populations depending on cereals as a main source of Zn is a global malnutrition problem. In this field study, we investigated the potential of green manure application to increase soil Zn availability and wheat grain Zn concentrations (biofortification) on a Luvisol with different long-term fertilizer management. We also studied cadmium (Cd), as wheat is a major contributor of this undesired non-essential element to human diets. Clover (Trifolium alexandrinum L.), mustard (Sinapis alba L.) or no green manure was grown on field plots which had been managed with farmyard manure or mineral fertilizers for 65 years in Switzerland. After green manure incorporation into the soil, spring wheat (Triticum aestivum L.) was grown on all...

The technological and organizational solutions the agricultural sector has undertaken in the past are not always compatible with the constraints and opportunities that the rural economy and society will face in the future. There is growing agreement that the goal of sustainability cannot be fulfilled without a profound change in the way the economy is organized. Innovation policies are among the most suitable instruments for this purpose. The article, based on the SOLINSA conceptual framework, adopts a network approach to innovation policies. Based on empirical evidence collected from case studies across Europe in the first phase of the project, the paper proposes the concept of Learning and Innovation Networks for Sustainable Agriculture (LINSA).

Autores: Schleuß, Uwe.
In diesem Artikel geht es um die Umweltauswirkungen von Kupfer, die für den Ökolandbau zugelassenen Pflanzenschutzmittel und die Anwendungsgebiete von Kupfer.    Zusammenfassend wird festgehalten, dass momentan auf den Einsatz von Kupfer als Pflanzenschutzmittel im ökologischen Landbau  noch nicht verzichtet werden kann. Um die Umweltauswirkungen auf Boden und Gewässer so gering wie möglich zu halten, muss die Aufwandmenge deutlich reduziert werden. Dabei muss natürlich die fungizide Wirkung erhalten bleiben. Ein Durchbruch beim Ersatz von Kupferpräparaten ist hinsichtlich Wirksamkeit und Kontinuität noch nicht gegeben. Deshalb ist zunehmend mehr Wert auf Präventionsmaßnahmen zu legen.

The aim of this review is to provide an update on factors contributing to quality of carrots, with special focus on the role of pre- and postharvest factors and processing. The genetic factor shows the highest impact on quality variables in carrots, causing a 7–11-fold difference between varieties in content of terpenes, β-carotene, magnesium, iron and phenolics as well as a 1–4-fold difference in falcarindiol, bitter taste and sweet taste. Climate-related factors may cause a difference of up to 20-fold for terpenes, 82% for total sugars and 30–40% for β-carotene, sweet taste and bitter taste. Organic farming in comparison with conventional farming has shown 70% higher levels for magnesium and 10% for iron. Low nitrogen fertilisation level may cause up to...

Soil nutrient levels define herbage yield but not root biomass in a multispecies grass-legume ley
Provedor de dados: 21

The response of above- and below-ground biomass to soil nutrient availability is crucial for estimating belowground carbon input and predicting changes in soil carbon storage. However, the response is far from clear at plant community level, especially for grassland systems. Using a long-term field experiment initiated 123 years ago with varying soil nutrient levels (deficient, sub-optimal, optimal and over-optimal) established by use of two nutrient sources (animal manure or mineral fertiliser), we examined the effects of soil nutrient level and source on herbage yield and composition, root biomass and root-to-shoot (R/S) ratio of an unfertilised multispecies grass-legume ley. Increased nutrient levels enhanced herbage yield, but did not affect root...

Comparing intensive, extensified and organic grassland farming in southern Germany by process life cycle assessment
Provedor de dados: 21
Autores: Haas, Guido; Wetterich, Frank; Köpke, Ulrich.
To reduce the environmental burden of agriculture, suitable methods to comprehend and assess the impact on natural resources are needed. One of the methods considered is the life cycle assessment (LCA) method, which was used to assess the environmental impacts of 18 grassland farms in three different farming intensities - intensive, extensified, and organic - in the Allgäu region in southern Germany.  Extensified and organic compared with intensive farms could reduce negative effects in the abiotic impact categories of energy use, global warming potential and ground water mainly by renouncing mineral nitrogen fertilizer. Energy consumption of intensive farms was 19.1 GJ/ha and 2.7 GJ/t milk, of extensified and organic farms 8.7 and 5.9 GJ/ha along with 1.3...

The study investigated direct anthelmintic effects of sesquiterpene lactones (SL)-containing extracts from forage chicory against free-living and parasitic stages of Ostertagia ostertagi. Freeze-dried leaves from chicory cultivars ‘Spadona’ and ‘Puna II’ were extracted using methanol/water. Total SL were further fractionated by solid-phase extraction and resulting extracts were characterised by high-performance liquid chromatography (HPLC). O. ostertagi eggs from faeces of mono-infected calves were hatched and L1 were used in a larval feeding inhibition assay (LFIA), while cultured L3 were used in a larval exsheathment inhibition assay (LEIA). Adult worms were immediately recovered after slaughter and used for motility inhibition assays (AMIA). Electron...

Obstacles, levers and impacts of organic farming development in Camargue
Provedor de dados: 21
Autores: Delmotte, Sylvestre; Lacombe, C; Couderc, Vincent; Mailly, F; Mouret, J.C.; Lopez-Ridaura, S; Barbier, J.M.
We are presenting an analysis of the obstacles and levers for the development of organic cropping systems in Camargue, documented with a multicriteria analysis of scenarios of organic farming (OF) development. This communication is built using results from on-farm agronomic monitoring, stakeholders and farmers’ interviews and the use of models for integrated assessment of scenarios. At the farm level, the obstacles are related to identification of profitable cropping systems and rotations that include enough rice, conversion being therefore risky as impacting financial management and requiring a labour reorganisation. At the regional level, the constraints are related to the absence of advisory services for technical issues, and to the lack of coordination...

Project for a European technological platform on organic agriculture: Vision for an Organic Food and Farming Research Agenda to 2025
Provedor de dados: 21
Autores: NIGGLI,.
Facing global problems like food security, the unsustainable use of natural resources, the degradation of soils and biodiversity as well as climate change, international experts demand a strategy change in agriculture and in agricultural research. Such a change encompasses not only re-establishing principles like closing cycles in agro-ecosystems, making best use of regulating and supporting ecosystems services but also making use of indigenous or tacit knowledge of farmer communities in addition to technological progress. The reports of the “Millennium Ecosystem Assessment” and of the IAASTD highlighted the need for this change in 2005 and 2008. Influenced by these recommendations, the potential of organic food and farming systems have to be assessed for...

Autores: Kendall, Helen; Kuznesof, Sharron; Dean, Moira; Chan, Mei-Yen; Clark, Beth; Home, Robert; Stolz, Hanna; Zhong, Qiding; Liu, Chuanhe; Brereton, Paul; Frewer, Lynn.
Regulation of food systems exists to ensure safety and enhance consumer confidence in the food which they purchase and consume. However, some regulatory systems fail to instil public confidence. In China for example, trust in the domestic food system is low as a consequence of multiple high-profile food scandals, many of which linked to food fraud. Fraud occurs when food is intentionally adulterated for economic gain and may, but not always, pose a risk to the safety of food. Food authenticity and quality may also be compromised. The focus of this research relates to how Chinese consumers perceive food fraud and make choices in the absence of trust in regulatory systems. Seven focus groups with middle class Chinese participants in tier 1 and 2 cities...

What drives farmers’ sustainability performance? Application of the CSP Modell for the analysis of farmers’ Conditions, adaptation Strategies and sustainability Performances – a case study analysis of German and Swedish producer groups in times of change
Provedor de dados: 21
Autores: Münchhausen, von, Susanne; Knickel, Karlheinz; Milestad, Rebecka; Lasner, Tobias.
This paper aims to explore farmers' conditions, strategies and performances in a context of multi-dimensional policy requirements, market imperfections and globalisation. The basic assumption sees conditions as drivers for farmers’ strategies that then result in performances of the sector. The methodological approach is based on the Conditions-Strategies-Performances (CSP) model which is used for the analysis of three case studies. The model helps to identify changes in framework conditions over time, resources among relevant groups of primary producers, adaptation strategies and finally, to explore the related social, economic and environmental effects. The analysis is based on three case studies, three farmers’ groups in Germany and Sweden. Results show...

Undersåning af bælgplanter til grøngødskning
Provedor de dados: 21
Autores: Sørensen, Dr. Jørn Nygaard; Thorup-Kristensen, Dr. Kristian.
Forsøg ved Danmarks JordbrugsForskning i Årslev har vist, at det er muligt at opnå høje udbytter af salat ved grøngødskning, som blev etableret ved undersåning i korn året forinden. Efter høst af kornet voksede bælgplanterne videre. De opsamlede ikke alene kvælstof fra luften, men også fra jorden. Bælgplanterne medvirkede herved til at nedsætte risikoen for kvælstofudvaskning i løbet af vinteren. Undersåning af bælgplanter til grøngødskning kan ikke alene anvendes ved økologisk dyrkning af grønsager, men også ved konventionel dyrkning hvorved det er muligt at spare på gødningstilførslen.

Root carbon input in organic and inorganic fertilizer-based systems
Provedor de dados: 21
Autores: Chirinda, N.; Olesen, Jørgen E.; Porter, J.R.
In agroecosystems, carbon (C) inputs come from applied manures, plant roots and retained shoot residues. Whereas the manure and shoot derived C inputs can be relatively easily determined, high costs associated with root measurements have caused current knowledge of in situ root C input to remain scant, hence it may be considered a "black box". This study aimed at determining root biomass C and nitrogen (N) in response to nutrient management and soil fertility building measures (green manures and catch crops). We made use of one inorganic fertilizer-based and four organic arable cropping systems in an 11-year-old field experiment on a sandy loam soil. Shoots and roots of catch crop mixtures and cereals sampled in 2008 and 2010 were characterized for dry...

Automated intelligent rotor tine cultivation and punch planting to improve the selectivity of mechanical intra-row weed control
Provedor de dados: 21
Autores: Rasmussen, Jesper; Griepentrog, Hans W.; Nielsen, J.; Henriksen, Christian Bugge.
There is much emphasis on technical aspects related to sensor or mapping techniques, which enable so-called intelligent cultivators to target the intra-row spaces within crop rows. This study investigates (i) an expected advantage of an intelligent rotor tine cultivator (the cycloid hoe) in terms of crop-weed selectivity and (ii) an expected synergistic effect between  punch planting and post-emergence weed harrowing in terms of improved crop-weed selectivity. Selectivity is defined as the relationship between weed control and associated crop density decline one week after cultivation, and punch planting is a sowing technique where holes are created in the ground with a minimum of soil disturbance and seeds are inserted into them, without soil disturbance...

Improving sustainability of organic tomato value chains requires increase of production and reduction of losses and related environmental burden. This paper presents the study conducted on organic tomato produced and consumed in Sweden. Using life cycle analysis (LCA) method with SimaPro8.2 LCA software, the cumulative energy demand (CED) and global warming potential (GWP100) were investigated within the system boundary of cradle-to-consumer gate. The system was modeled as fresh tomato value chain (FTVC) and dried tomato value chain (DTVC). The functional unit (FU) was 1 ton of fresh product at farm that will be delivered to customer either as fresh or dried tomato. Sensitivity analysis was done considering changes in drying energy consumption. The results...

Effects of landscape context on herbivory and parasitism at different spatial scales
Provedor de dados: 21
Autores: Thies, Carsten; Steffen-Dewenter, Ingolf; Tscharntke, Teja.
Local community structure and interactions have been shown to depend partly on landscape context. In this paper we tested the hypothesis that the spatial scale experienced by an organism depends on its trophic level. We analyzed plant-herbivore and herbivore-parasitoid interactions in 15 agricultural landscapes differing in structural complexity using the rape pollen beetle (Meligethes aeneus), an important pest on oilseed rape (Brassica napus), and its parasitoids. In the very center of each landscape a patch of potted rape plants was placed in a grassy field margin strip for standardized measurement. Percent non-crop area of landscapes was negatively related to plant damage caused by herbivory and positively to the herbivores’ larval mortality resulting...

Monitoring and optimization of drying fruits and vegetables process using computer vision: a review
Provedor de dados: 21
Autores: Raponi, Flavio; Moscetti, Roberto; Monarca, Danilo; Calantoni, Andrea; Massantini, Riccardo.
An overview is given regarding the most recent use of non-destructive techniques during drying used to monitor quality changes in fruits and vegetables. Quality changes were commonly investigated in order to improve the sensory properties (i.e., appearance, texture, flavor and aroma), nutritive values, chemical constituents and mechanical properties of drying products. The application of single-point spectroscopy coupled with drying was discussed by virtue of its potentiality to improve the overall efficiency of the process. With a similar purpose, the implementation of a machine vision (MV) system used to inspect foods during drying was investigated; MV, indeed, can easily monitor physical changes (e.g., color, size, texture and shape) in fruits and...

Vigorous seedlings are an important base for vegetable production. Beside the availability of appropriate amounts of nutrients, the health of seedlings is decisive. Soil-borne diseases are a challenging problem in organic seedling production. Here, we present results on the development of disease-suppressive growing media. Three aspects were examined: (i) use of different components of growing media (peat, coconut fiber, wood fiber, compost), (ii) influence of selected organic nitrogen fertilizers and (iii) use of different microorganisms (including commercial biocontrol agents (BCA)). Three plant-pathogen systems were used in this study: cucumber-Pythium ultimum, cress-Pythium ultimum and basil-Rhizoctonia solani. Green waste compost showed a good...

Rothår og fosforopptak i korn
Provedor de dados: 21
Autores: Holten, Jon Magne; Løes, Anne-Kristin.
Lavere nivå av fosfor i jorda er rapportert på gårder med økologisk drift. Jordbruksvekster kan til en viss grad tilpasses lavere fosfornivå ved utvalg og avl for høgere fosforeffektivitet. Danske forsøk har vist at lange rothår kan være en faktor som øker fosforopptaket i korn. Funn fra et nylig avsluttet MSc-arbeid tyder på at det er forskjell i fosforopptaksevne mellom bygg- og hvetesorter, men at andre faktorer enn rothår har vel så i stor betydning for fosforopptaksevnen.

Consumer Perception of Local and Organic Products: Substitution or Complementary Goods?
Provedor de dados: 21
Autores: Naspetti, Simona; Bodini, Antonella.
Many consumers are interested in local products because of the perceived benefits of freshness, stronger taste and higher quality. To consumers the origin attribute represents a strong purchasing criterion. With respect to organic produce, local food products may be perceived either as substitutes or as complementary. A qualitative approach to data collection (focus groups) and to data processing (content analysis) has been used to analyse Italian consumers’ perception with respect to local and organic food products. In the framework of the EU project QLIF (FP6-506358) a discussion guide to focus group interview was used in order to identify important purchase criteria, the willingness to pay, as well as the role of organic food products in purchasing...

Conservation value of the herbaceous vegetation in hedgerows - does organic farming make a difference?
Provedor de dados: 21
Autores: Aude, Erik; Tybirk, Knud; Michelsen, Anders; Ejrnæs, Rasmus; Hald, Anna Bodil; Mark, Susanne.
The aim was to compare and test differences in the conservation value of hedge bottom vegetation on organic and conventional farms. The studied hedgerows (28 organic and 28 conventional) were on average 14 years old and established in the same way, except that organic hedgerows were established and managed without use of pesticides. We investigated three sample plots of 10 m2 in all hedgerows together with a set of 13 explanatory variables. There were no differences in soil texture between hedgerow types but organic farms had higher pH and lower conductivity. Organic farms had higher total N values, which are explained by a slightly higher content of organic matter. There was highly significant interaction between farming type and neighbouring crop type...

Below- and aboveground production in cocoa monocultures and agroforestry systems
Provedor de dados: 21
Autores: Niether, Wiebke; Schneidewind, Ulf; Fuchs, Michael; Schneider, Monika; Armengot, Laura.
Farmers expect yield reduction of cash crops like cocoa when growing in agroforestry systems compared to monocultures, due to competition for resources, e.g. nutrients and water. However, complementarities between species in the use of resources may improve resource use efficiency and result in higher system performance.  Cocoa trees have a shallow rooting system while the rooting characteristics of the associated trees are mainly unknown. This work investigates fine root distribution and production in five cocoa production systems: two monocultures and two agroforestry systems under conventional and organic farming, and a successional agroforestry system. In the organic systems a perennial leguminous cover crop was planted and compost was added, while...

In a field trial comprising organic farming and minimum tillage management strategies in Scheyern, Germany, we evaluated the long-term (21-year) effects of organic farming (use of a diverse crop rotation with legume cover crop and without application of synthetic fertilizer or pesticides) and minimum tillage (6–8 cm depth) on the microbial community structure and microbial residues in Cambisols. Organic farming had a positive effect on microbial biomass, total phospho-lipid fatty acids (PLFA), Gram (+) bacteria, Gram (-) bacteria and the arbuscular mycorrhizal fungi (AMF) indicator PLFA 16:1v5 and amino sugars. The increase in presence of Gram (+) bacteria when compared to integrated farming was also reflected by increased content of bacterial muramic acid...

Simulated nitrogen leaching, nitrogen mass field balances and their correlation on four farms in south-western Finland during the period 2000-2005
Provedor de dados: 21
Autores: Rankinen, Katri; Salo, Tapio; Granlund, Kirsti; Rita, Hannu.
Nitrogen (N) gross balance is one of the indicators designed for following developments in agriculture in the European Union. A nutrient surplus occurs when the quantity of a nutrient applied in fertilizers is greater than that removed during harvest. In this study the usefulness of N balance in studying the fate of N and controlling N leaching from agricultural fields in south-western Finland was evaluated. To estimate N leaching in 2000–2005 the mathematical, process-based model COUP was applied to twelve fields representing four agricultural production sectors. The fields represented conventional cereal production, organic cereal production and both conventional cattle and pig husbandry. Simulated N leaching was lowest from cereal production fields with...

Landscape Structure and Biological Control in Agroecosystems
Provedor de dados: 21
Autores: Thies, Carsten; Tscharntke, Teja.
Biological pest control has primarily relied on local improvements in populations of natural enemies, but landscape structure may also be important. This is shown here with experiments at different spatial scales using the rape pollen beetle (Meligethes aeneus), an important pest on oilseed rape (Brassica napus).  The presence of old field margin strips along rape fields was associated with increased mortality of pollen beetles resulting from parasitism and adjacent, large, old fallow habitats had an even greater effect. In structurally complex landscapes, parasitism was higher and crop damage was lower than in simple landscapes with a high percentage of agricultural use.

Autores: Grando, Stefano; Carey, Joy; Hegger, Els; Jahrl, Ingrid; Ortolani, Livia.
Short food supply chain (SFSCs) initiatives have developed throughout Europe as an alternative to the long industrialized chains characterizing the contemporary global food industry. They are often driven by small-scale actors belonging to different phases of the chain (producers, retailers, consumers) and rooted in specific territorial contexts. Innovative organizational models of SFSCs are attracting interest in the academic field (Jarosz, 2008, Khan and Prior, 2010, Aubry and Kebir, 2013) and beyond (RUAF, 2015). This work contributes to the debate with a focus on the logistics of SFSCs in urban and peri-urban areas across Europe, specifically on the role of local intermediaries in facilitating connections between urban consumers and peri-urban and...

Planos de uso como ferramenta de gestão comunitária dos recursos naturais em unidades de conservação no Brasil 1.
Provedor de dados: 21
Autores: Sacramento, José Maria Cardoso; Schmitz, Heribert.
O objetivo do artigo é analisar os planos de uso de propriedades rurais como instrumento para estabelecer as regras da gestão comunitária dos bens comuns nas diferentes tipos de unidade de conservação. Os planos pretendem contemplar as reivindicações dos camponeses por uma reforma agrária que não apenas garanta a propriedade rural, mas combine a preservação dos recursos naturais com a realização de atividades agroextrativistas. Esse trabalho questiona a contribuição do plano de uso como um elemento orientador para a realização das atividades na unidade de conservação. Demonstramos que o planejamento é uma ideia presente, mesmo de maneira indireta, em diferentes escolas de pensamento que tratam o desenvolvimento rural, como a agroecologia e a permacultura....

The knowledge of factors implicated in agroecosystem diversity is necessary to better evaluate their role. The study aims to link within-field plant diversity, cultural practices, and landscape context with terrestrial predatory arthropods in mango orchards on Reunion. Twenty-four plots distributed within the mango production area have been studied. Arthropods were sampled with pitfall traps. The land plots were grouped into three groups of agricultural practice intensity. The landscape was mapped within a circle of 400 meters around the orchards, which permitted to distinguish three different landscape contexts. Based on 83181 arthropods collected, 65124 were determined as predators, their communities were mainly composed of ants (Hymenoptera: Formicinae)...

A polyocular framework for research on multifunctional farming and rural development
Provedor de dados: 21
Autores: Noe, Egon; Alrøe, Hugo F.; Langvad, Anne Mette S.
The paradox of multifunctionality is that, on the one hand, the specialized functionalities of agriculture only arise because of the functional differentiation of social systems and scientific disciplines and, on the other hand, multifunctionality can only enter as a way to mediate between conflicts, interests and fragmented knowledge when different functions and observations of functions combine. The aim of this paper is to contribute to a theoretical and methodological platform for multidisciplinary research on multifunctional farming. With the notions of polyocular cognition and polyocular communication we introduce a second order, interdisciplinary communication process that can meet the challenge of creating a shared view on multifunctional farming....

Simulating root growth
Provedor de dados: 21
Autores: Pedersen, Anders; Thorup-Kristensen, Kristian; Kristensen, Hanne Lakkenborg; Berntsen, Jørgen.
Dynamic plant/soil models are used to predict crop production, N dynamics and nitrate leaching loss of different cropping systems. To do this, the models simulate various aspects of plant biology, soil biology and soil physics. Correct simulation of root growth is critical for the simulation of nitrate leaching losses. Measurements have been made on crop root growth on two soil types, and the data used to improve the simulation of root growth within the FASSET model. The paper presents the results from root measurements on winter wheat, spring barley and sugar beets, and the root modelling approach we have developed.

Effect of cultural methods on leaf spot (Mycosphaerella fragariae Tul.) incidence in strawberries
Provedor de dados: 21
Autores: Schmid, Andi; Daniel, Claudia; Weibel, Franco.
Introduction:  Leaf spot caused by Mycosphaerella fragariae Tul. is one of the most common diseases of strawberry. The control of leaf spot mostly relies on the application of protective fungicides (MAAS 1998). In organic agriculture the use of copper products is effective (VUKOVITS 1980) but this has a negative influence on soil fertility.(BERGMANN 1993).Therefore its use in strawberry crops should also be reduced.

Influence of catch crops on phosphorous and potassium availability in a depleted loamy soil
Provedor de dados: 21
Autores: Jensen, Lars Stoumann; Pedersen, Anders; Magid, Jakob; Nielsen, Niels Erik.
Although catch crops and green manures are known to greatly influence nitrogen loss and availability for the succeeding crop, an experiment with catch crops and green manures on a long-term nutrient depletion trial showed no ability to mobilize phosphorous and potassium resources on this low fertility site. The study reported here indicated that this may be due to the limited biomass productivity of catch crops on such low fertility soils.

Autores: Hansen, Thomas Hesselhøj; Laursen, Kristian Holst; Persson, Daniel Pergament; Pedas, Pai; Husted, Søren; Schjørring, Jan Kofod.
Quantitative multi-elemental analysis by inductively  coupled plasma (ICP) spectrometry depends on a complete digestion of solid samples. However, fast and thorough sample digestion is a challenging analytical task which constitutes a bottleneck in modern multi-elemental analysis. Additional obstacles may be that sample quantities are limited and elemental concentrations low. In such cases, digestion in small volumes with minimum dilution and contamination is required in order to obtain high accuracy data.     Results  We have developed a micro-scaled microwave digestion procedure and optimized it for accurate elemental profiling of plant materials (1-20 mg dry weight).

Autores: Bloemhof, S.; Mathur, P. K.; Knol, E. F.; van der Waaij, E. H.
Heat stress is known to adversely affect reproductive performance of sows. However, it is important to know on which days or periods during the reproduction cycle heat stress has the greatest effects for designing appropriate genetic or management strategies. Therefore, this study was conducted to identify days and periods that have greatest effects on farrowing rate and total born of sows using 5 different measures of heat stress. The data consisted of 22,750 records on 5,024 Dutch Yorkshire dam line sows from 16 farms in Spain and Portugal. Heat stress on a given day was measured in terms of maximum temperature, diurnal temperature range and heat load. The heat load was estimated using 3 definitions considering different upper critical temperatures....

Comparison between conventional and organic agriculture in terms of nutritional quality of food - a critical review
Provedor de dados: 21
Autores: Jensen, Maja M.; Jørgensen, Henry; Lauridsen, Charlotte.
The consumption of organic foods has been increasing over the last decades and organic products are becoming more visible on the market. Consumers perceive that organic foods are of better quality, more nutritious and healthier, and these perceptions are some of the main drivers of the organic market. Scientific research on organic foodstuffs is contradictory, and knowledge regarding the effect of cultivation system on the nutritive value and the possible relationship with human health could be further explored. Although some systematic differences in the nutritional content, i.e. nitrogen, protein, vitamin C, phosphorous and phenolic compounds of plant products grown under different cultivation systems have been observed, it is a difficult task to prove...

Catch Crop Residues Stimulate N2O Emissions During Spring, Without Affecting the Genetic Potential for Nitrite and N2O Reduction
Provedor de dados: 21
Autores: Duan, Yun-Feng; Hallin, Sara; Jones, Christopher M.; Priemé, Anders; Labouriau, Rodrigo; Petersen, Søren O.
Organic agriculture depends on recycling of N to sustain crop production, and the use of catch crops to prevent leaching losses during winter is part of this strategy. The finding in this study, that catch crop residues were a more consistent source of nitrous oxide emissions in spring than synthetic fertiliser, indicates catch crop residue decomposition may contribute negatively to the climate impact of the farming system. Management practices are needed that reduce the potential for denitrification, which is the main source of nitrous oxide. Possible strategies include cultivation to promote aerobic rather than anaerobic degradation, and timing of manure application to avoid that mineral N from manure accumulates during residue decomposition....

The ranging ability of sasso chickens grown under various types of agroecosystems
Provedor de dados: 21
Autores: Escobin, Jr., Dr Rectorino; Bondoc, Dr. Orville; Lambio, Dr. Angel; Arboleda, Dr. Cecilio; Dagaas, Dr. Claire.
The ranging ability of Sasso chicken was estimated using the ranging score as an indicator.  The chickens were allowed to range in three agro-ecosystems namely, rice-based, rambutan orchard and grassland.  The ranging score was significantly higher in rambutan orchard with 52 m-hr followed by the ranging score in grassland with 48 m-hr.  The ranging score was lowest in rice-based agroecosystem.    The differences in the ranging score among agroecosystem can be attributed mainly to the presence of trees as shade, the soil type, and the predominant weed species in each agroecosystem.  It was found that the higher the ranging score, the more the chicken used their daytime for the ranging acts i.e. “kahig at tuka”.    As a result of ranging, there was a net...

The mineralization rate of a commercial organic fertiliser was evaluated over the course of three years in an organic rice field in the Camargue (France). The effect of different mounts of fertiliser applied at different periods was tested. The organic fertiliser rapidly mineralised under flooded conditions. On the basis of this result, we demonstrated that an adaptation of organic fertilisation practices, similar to those employed for mineral fertilisers, would result in the optimisation of organic fertilisers, leading to improved profitability.

Non-compliance in organic farming: A cross-country comparison of Italy and Germany
Provedor de dados: 21
Autores: Gambelli, Danilo; Solfanelli, Francesco; Zanoli, Raffaele; Zorn, Alexander; Lippert, Christian; Dabbert, Stephan.
This paper describes the Italian and German organic certification systems, including the institutions involved and the definitions of non-compliance and sanctions. Although they are both implementations of the same EU regulatory framework, these systems differ in many respects. Case study data from control bodies on non-compliance and sanctions are presented and analysed using binary choice models. This analysis shows that the occurrence of slight non-compliance and greater farm acreage are significant risk factors that explain severe non-compliance in both countries. However, to implement an efficient risk-based inspection system in the future, the data collection process must be improved and extended to examine personal attributes of  farmers and...

Long-term feasibility of reduced tillage in organic farming
Provedor de dados: 21
Autores: Armengot, Laura; Berner, Alfred; Blanco-Moreno, José Manuel; Mäder, Paul; Sans, F.Xavier.
Agricultural practices, and mainly soil tillage, highly contribute to the emissions of greenhouse gases such as CO2 and N2O. Reducing the tillage improves the quality of the soil and may help mitigating the greenhouse emissions. In Europe, approximately 25 % of the arable land is managed under reduced tillage practices, including both notill and reduced tillage. However, they have been developed mainly in herbicidemanaged systems. The potential increase in weed infestation caused by the lack of soil inversion may threaten crop yields, and is one of the major drawbacks for the adoption of reduced tillage among organic farmers. We report the results from a field experiment comparing the reduced tillage with respect to the conventional tillage in the...

Bio-economic analysis of dual-purpose management of winter cereals in high and low input production systems
Provedor de dados: 21
Autores: Ates, S.; Cicek, H.; Gultekin, I.; Yigezu, Y. A.; Keser, M.; Filley, S. J.
Dual-purpose (DP) management of cereals holds promise to reduce the feed gap and to better integrate crop and livestock systems especially in drylands where forage deficit is severe. However, there is limited information on which cereal species and type of management would be most optimal for both forage and grain production in dry highland environments. A two-year field study (2013–2015) in the Central Anatolian plateau of Turkey investigated the effect of spring defoliation of barley, triticale and wheat varieties at tillering and stem elongation stages and a no-cut (grain-based) system under low- and high-input management on yield and quality of forage, straw and grain. Overall, barley had greater (P &lt; 0.01) forage DM accumulation within the...

Physical properties of synthetic bedding materials for free-stall dairy cow
Provedor de dados: 21
Autores: Ruunaniemi, Jukka; Hautala, Mikko; Ahokas, Jukka.
Rest is a prerequisite for the well-being of cows and they spend 40–50% of the time lying down. In this study the basic physical properties, the friction coefficient, heat flux as a function of time and softness of the bedding materials were measured. The heat flux to the bedding was shown to be large enough to affect the cow’s heat balance. The friction coefficients of most of the tested materials were not within the recommended 0.3–0.5. However, the friction values are only indicative, as the material and the shape of the arti- ficial hoof were not identical to natural hooves. There were also differences of almost an order of magnitude in the softness (Young’s modulus) of the mats. Demands for softness vary according to the type of building and cow’s...

BACKGROUND: Plant extracts might provide sustainable alternatives to copper fungicides, which are still widely used despite their unfavourable ecotoxicological profile. Larch bark extract and its constituents, larixyl acetate and larixol, have been shown to be effective against grapevine downy mildew (Plasmopara viticola) under semi-controlled conditions. The aim of this study was to reduce the gap between innovation and the registration of amarketable product, namely to develop scalable extraction processes and to evaluate and optimise the performance of larch extracts under different conditions.  RESULTS: Toxicologically and technically acceptable solvents like ethanol were used to extract the active compounds larixyl acetate and larixol from bark in...

UPLC Rapid Quantification of Ascorbic Acid in Several Fruits and Vegetables Extracted Using Different Solvents
Provedor de dados: 21
Autores: Cotrut, Ramona; Badulescu, Liliana.
Ascorbic acid or vitamin C is mostly found in natural products such as fruits and vegetables. Ultra performance liquid chromatography (UPLC) method has been developed to compare the ascorbic acid content in some fresh fruits (apple, orange) and vegetables (carrot, beet, cherry tomato) extracts with two different extraction solvents; i) 9% metaphosphoric acid, ii) 3% citric acid.  The compound has been detected and quantified by the use of UPLC equipped with Photodiode Array (PDA) detector.  The amount of ascorbic acid detected in fruits and vegetables extracts prepared with the two solvents mentioned was different. For the orange extracted using citric acid 3% recorded the highest concentration of ascorbic acid (38.2mg/100g FW) higher than with 9%...

Concept for quality management to secure benefits of compost use for soil and plants
Provedor de dados: 21
Autores: Fuchs, J.G.; Berner, A.; Mayer, J.; Schleiss, K.
Use of quality compost can have an important positive impact on soil fertility and plant growth and health. For example, it increases soil humus and improves soil structure and suppressivity towards plant diseases. To obtain these positive results, it is important that the compost quality is appropriate for each use. If used inadequately, the impact of compost can also be negative. The compost producer should be responsible for the quality of his products, and has to communicate the properties of his composts to the users. But to be successful, the compost users have to communicate to the producers the manner in which the compost is to be used. To support compost producers and users in this process, the Swiss producers of compost and digestate published a...

The turnover of soil organic matter on different farm types
Provedor de dados: 21
Autores: Petersen, B.M.; Berntsen, J.
One of the prime factors determining soil fertility is the content of soil organic matter. A huge amount of nitrogen (N) is bound in organic matter, and the yearly mineralisation of N in the field is only a small fraction of the total organic nitrogen.The release and incorporation of organic N is of special relevance for organic farms, where the crop supply mainly depends on N mineralised from organic matter.In order to study the long-term balance between build-up and degradation of organic matter, a simple simulation model was made, calibrated on the basis of long-term data from Sweden, U.K. and Denmark. Briefly, it is a 3-pool model (Figure 1) employing first-order kinetics, which is implemented in C-TOOL. The long-term build up or breakdown of organic N...

Intensiﬁcation of agriculture, combined with poor agronomic practices have increased the incidence of plant parasitic nematodes (PPN) and other soil pathogens in East Africa, which consequently aﬀects crop productivity in small holder farms. The objective of the study was to assess the eﬀectiveness of farming systems in management of PPN and to recommend the best practice to farmers. Therefore, two ﬁeld trials were established, one infarmer ﬁeldsandoneon-station,usingmaize (Zeamays L.), intercroppedwithbeans(Phaseolusvulgaris L.) and in rotationwith beans as asole crop.

Pollen dispersal of genetically modified oilseed rape to organic fields: Analysis of available data and the possibilities for co-existence
Provedor de dados: 21
Autores: Kjellsson, Gösta; Damgaard, Christian.
Results from model estimations based on existing data on gene dispersal in oilseed rape indicate that the GM dispersal by pollen to organic fields primarily can be limited by the use of isolation distances. The results also indicate that because of pollen dilution, large fields are better protected from GM pollen dispersal than smaller fields. For large fields (i.e. field width &gt; 200 m), the risk of dispersal from GM fields by pollen will be limited (approx. 0.1%) at distances above 100 m. For small fields (i.e. width = 50 m), some GM pollen dispersal (up to approx. 0.3%) may be expected even with an isolation distance of 200 m. If the fields are very close, the use of additional protective buffer zones may be required.

Permaculture for Agroecology: Design, Practice, Movement, and Worldview. A Review
Provedor de dados: 21
Autores: Ferguson, Rafter Sass; Lovell, Sarah Taylor.
Agroecology is a promising alternative to industrial agriculture, with the potential to avoid the negative social and ecological consequences of input-intensive production. Transitioning to agroecological production is, however, a complex project that requires diverse contributions from outside of scientific institutions. Agroecologists therefore collaborate with tradtional producers and agroecological movements. Permaculture is one such agroecological movement, with a broad international distribution and a unique approach to system design. Despite a high public profile, permaculture has remained relatively isolated from scientific research. Though the potential contribution of permaculture to agroecological transition is great, it is limited by this...

Drought Tolerance of Land Races of Emmer Wheat in Comparison to Soft Wheat
Provedor de dados: 21
Autores: Konvalina, Petr; Moudry, Jan; Dotlacil, Ladislav; Stehno, Zdenek; Moudry, Jan (Jr.).
As water deficiency becomes a more frequent cause of the reduction in wheat yield levels, the search for donors of drought tolerance to be bred into adapted land races becomes urgent. Drought tolerance has been evaluated by the 13C discrimination method in six land races of emmer wheat (Triticum dicoccum SCHRANK), compared with land races, obsolete cultivars and modern varieties of soft wheat (Triticum aestivum L.). The results of a two-year trial show that most of the genetic resources of emmer wheat, and intermediate land races of wheat are predisposed to drought tolerance. These varieties respond to dry conditions more sensitively, as they close their pores earlier (a lower value of the discrimination of 13C isotope). As for other land races and the top...

Contribution of nitrification and denitrification to N2O emissions from urine patches
Provedor de dados: 21
Autores: Carter, Mette S.
Urine deposition by grazing livestock causes an immediate increase in nitrous oxide (N2O) emissions, but the responsible mechanisms are not well understood. A nitrogen-15 (15N) labelling study was conducted in an organic grass-clover sward to examine the initial effect of urine on the rates and N2O loss ratio of nitrification (i.e. moles of N2O-N produced per moles of nitrate produced) and denitrification (i.e. moles of N2O produced per moles of N2O + N2 produced). The effect of artificial urine (52.9 g N m-2) and ammonium solution (52.9 g N m-2) was examined in separate experiments at 45 and 35% water-filled pore space (WFPS), respectively, and in each experiment a water control was included. The N2O loss derived from nitrification or denitrification was...

Cooling Causes Changes in the Distribution of Lipoprotein Lipase and Milk Fat Globule Membrane Proteins between the Skim Milk and Cream Phase
Provedor de dados: 21
Autores: Dickow, J.A.; Larsen, L.B.; Hammershøj, M.; Wiking, L.
The development in lipoprotein lipase (LPL) activity and free fatty acids were studied in freshly milked non-cooled milk from individual Danish Holstein or Jersey cows, or after storage for up to 24 h at either cooling temperature at 4ºC or at the milking temperature at 31ºC. LPL activity increased in the cream phase upon cooling, while the activity in the skimmed milk was either steady, as observed for Jersey cows, or increased, as seen for the Holsteins, in the skim milk upon cooling for up to 24 h. Storage at 31ºC decreased the LPL activity in both the cream phase and the skim milk phase. The increase in free fatty acids was found to depend on potential lipoprotein lipase activity, incubation temperature, substrate availability, and incubation time....

Autores: Campos, Alessandro Torres; Campos, Aloísio Torres de.
No Brasil, pouca atenção se tem dado às formas e caminhos com que os fluxos energéticos se distribuem nos sistemas produtivos. Na agropecuária, a atenção tem sido voltada a novas fontes de energia (biomassa) ou em tecnologia alternativa, visando a racionalização do uso de energia fóssil ou elétrica. Entretanto, a agricultura tem se desenvolvido baseada fortemente na utilização intensiva de máquinas agrícolas, com conseqüente uso de combustíveis fósseis. Um fator de estrangulamento muito forte no consumo energético geral tem sido a utilização massiva de fertilizantes derivados do petróleo nos agroecossistemas.

Breeding for mycorrhizal symbiosis: focus on disease resistance
Provedor de dados: 21
Autores: Hohmann, Pierre; Messmer, Monika.
Modern plant breeding can no longer afford to ignore the interaction between plants and microbial key players. Increasing evidence suggests (i) that the expression of many plant traits (such as nutrient use efficiency or tolerances against biotic and abiotic stresses) is mediated by beneficial microorganisms and (ii) that there is an exploitable genetic base for the regulation of symbiotic relationships. Arbuscular mycorrhizal fungi (AMF) play a key role in many of these trait expressions. While much is known about their ability to mobilise nutrients (especially phosphorus), the complex mechanisms of AMF-mediated disease resistance have only started to become apparent within the past decade. Besides competition for root space and resources, AMF also have...

Bluetongue virus (BTV) antibodies were analysed in 27 Swiss calves born in 2016 at the age of 16–19 days using competitive enzyme-linked-immunosorbent-assay (cELISA) and virus neutralization test (VNT) (animal trial permission number: 75684). Obligatory documentation proved that 15 of 27 dams were BTV-8 vaccinated once or three times in 2008–2010. The offsprings of the non-vaccinated dams were seronegative. Two of three calves and 11 of 12 calves descending from dams who had been vaccinated one or three times, respectively, had BTV specific serum antibodies. As Switzerland is considered BTV-free from 2010 to 2016, it is likely that BTV-8 antibodies were transferred via colostrum. Furthermore, we confirmed neutralizing cross-reactivity of BTV-8 with BTV-4...

Farmers or consumers may ask about the environmental implications when choosing organic products. Is it sustainable to buy organic products from China or South America? How much does the long-distance transport affect the climate and carbon footprint of the products? And does the organic production in the countries concerned benefit the environment? These are some of the questions raised – and the point of departure for a recently finalized PhD study.

Autores: Carvalho, Daniel F. de; Silva, Dione G. da; Rocha, Hermes S. da; Almeida, Wilk S. de; Sousa, Eraldo da S.
The aim of this study was to quantify the water consumption and the crop coefficients (Kc) for the potato (Solanum tuberosum L.), in Seropédica, Rio de Janeiro (RJ), Brazil, under organic management, and to simulate the crop evapotranspiration (ETc) using the Kc obtained in the field and the ones recommended by the Food and Agriculture Organization (FAO). The water consumption was obtained through soil water balance, using TDR probes installed at 0.15m and 0.30m deep. At the different stages of development, the Kc was determined by the ratio of ETc and reference evapotranspiration, obtained by Penman-Monteith FAO 56. The crop coefficients obtained were 0.35, 0.45, 1.29 and 0.63. The accumulated ETc obtained in the field was 109.6 mm, while the ETc...

This paper reports the results of a seminar on poultry red mite (PRM), Dermanyssus gallinae. Eighteen researchers from eight European countries discussed life cycle issues of the mite, effects of mites on hens and egg production, and monitoring and control methods for PRM in poultry facilities. It was determined that PRM probably causes more damage than envisaged, with the cost in The Netherlands  alone reaching 11 million euro per annum. However a great deal is still unknown about PRM (e.g. reproduction, survival methods, etc.) and that PRM monitoring is an important instrument in recognising and admitting the problem and in taking timely measures. Currently, the most promising control method combines heating the hen house in combination with chemical...

Assim, num Argissolo Vermelho-Amarelo distrófico foram comparados os efeitos de sistemas de cultivo orgânico e convencional, para as culturas do tomate (Lycopersicum esculentum) e do milho (Zea mays), sobre a comunidade de organismos do solo e suas atividades. As populações de fungos,bactérias e actinomicetos, determinadas pela contagem de colônias em meio de cultura, foram semelhantes para os dois sistemas de produção. A atividade microbiana, avaliada pela evolução de CO2, manteve-se superior no sistema orgânico, sendo que em determinadas avaliações foi o dobro da evolução verificada no sistema convencional. O número de espécimes de...

Bioactive Compound Fingerprint Analysis of Aged Raw Pu’er Tea and Young Ripened Pu’er Tea
Provedor de dados: 21
Autores: Pedan, V.; Rohn, S.; Holinger, M.; Chetschik, I.
Abstract: Pu’er tea produced from Camellia sinensis var. assamica is a widely appreciated and consumed beverage that can be divided into two kinds of tea depending on the different fermentation processed used, the special sensory characteristics, and their chemical composition. However, authentication seems to be very important for such teas, as they are traded to comparatively high prices, especially in Europe. The results for selected biochemical markers showed that aged raw pu’er tea contained 210.2 mg GAE/g polyphenols, of which 2.2 mg/g were gallic acid, 16.1 mg/g theogallin, 35.1 mg/g (-)-epigallocatechin gallate, and 40.1 mg/g (-) epicatechin gallate, on average. Young ripened pu’er tea contained about 104.6 mg GAE/g polyphenols, of which 5.5 mg/g...

Earthworm species and burrows related to agricultural management of clover-grass rotations
Provedor de dados: 21
Autores: Krogh, P.H.; Lamandé, M.; Eriksen, J.; Holmstrup, M.
Clover grass is an important element in crop rotations due to its beneficial agronomic properties including nitrogen build-up, biodiversity stimulation and maintenance of soil macropores and it harvests very high levels of earthworm biomass. We studied the relationship between crucial ele-ments of a clover grass crop rotation and earthworm diversity and macropore depth distribution. The dominance of anecics increased from the annual crops to the perenial clover-grass. Aporrec-todea tuberculata decreased significantly Cattle grazing seems to favour coarse macropores made by anecics, Aporrectodea longa and Lumbricus terrestris. Our study stresses the importance of considering subsoil macropores to complete the picture of earthworm influence on soil...

A new arbuscular mycorrhizal, Paraglomus-like, fungal species (Glomeromycotina) was found and propagated in single-species cultures established from spores coming from Oman, Greece, Tunisia, and New Caledonia. The hyaline spores of the fungus are small, 17–67 μm diam. when globose. Their spore wall consists of an evanescent, 1.0–2.3 μm thick, short-lived outer layer and a laminate, smooth, 3.8–7.3 μm thick inner layer, of which none shows amyloid or dextrinoid reaction in Melzer's reagent. Mycorrhizal structures (arbuscules and hyphae without vesicles) of the fungus stained slightly in Trypan blue, thus like those of the formerly described Paraglomus spp., in which the histochemical feature has been recognized.

Concepts of plant health – reviewing and challenging the foundations of plant protection
Provedor de dados: 21
Autores: Döring, Thomas; Pautasso, Marco; Finckh, Maria R.; Wolfe, Martin.
Plant health is a frequently used but ill-defined term. However, there is an extensive literature on general health definitions and health criteria in human medicine. Taking up ideas from these philosophical debates, concepts of plant health are reviewed and a framework developed to locate these concepts according to their position in several philosophical controversies. In particular, (i) the role of values in defining plant health in a naturalist versus a normativist approach; (ii) negative and positive definitions of plant health; (iii) reductionist versus holistic perspectives; (iv) the focus on functionality versus resilience, i.e. the ability of the plant to perform under stress with or without human interference; (v) materialist versus vitalist...

Technique of pneumatic pest control – analyses and a new device
Provedor de dados: 21
Autores: Schäfer, Winfried.
Pest control in organic production of berries, potatoes and vegetables usually employs spreading technique of registered phytopharmaceutical agents. This technique may be supported or even replaced by pneumatic pest control. Pneumatic pest control means suction of pest using a vacuum device similar to a home vacuum cleaner. Up to now there is no evaluation of pneumatic pest control available from an agricultural engineering point of view. This paper concerns the following questions: Which techniques of pneumatic pest control are available and how may these techniques be improved in terms of technical and physical parameters? Based on the answers a new device design is presented.

Reduction of spore spread of common bunt (Tilletia tritici) via combining equipment
Provedor de dados: 21
Autores: Kristensen, Lars; Borgen, Anders.
The disease common bunt (Tilletia tritici syn. T.caries) has become a more frequent problem in Europe during the last 15 year. In organic farming, common bunt causes serious problems for seed producers, and many seed lots are discarded due to contamination with Tilletia tritici. Due to the biology of Tilletia tritici, with spores loosely attached to the surface of the grain, there is a risk that spores can be disseminated via grain handling equipment, including combine harvesters. Preventive efforts should focus on the role of grain handling equipment, and how the fungus life cycle can be broken. We have investigated the dissemination of spores via the combiner after harvesting infected fields. We conducted six trials over three years, counting the number...

To what extent does organic farming rely on nutrient inflows from conventional farming?
Provedor de dados: 21
Autores: Nowak, B.; Nesme, T.; David, Christophe; Pellerin, S.
Nutrient management is a critical factor for organic farming. European organic regulations ban the use of artificial fertilisers. However organic farms may import nutrients coming from conventional farming. In this study we quantified the magnitude of nitrogen (N), phosphorus (P) and potassium (K) inflows from conventional farming to organic farming for 63 organic farms located in three French agricultural districts characterized by their degree of specialisation (crop productions, animal productions or both). Inflows from conventional farming amounted to 23%, 73% and 53% for N, P and K, respectively. These inflows were strongly correlated with farm production systems and positively correlated with the fertilisor demand of the farms.

Jahrzehntelang wurden Milchrinderrassen fast ausschließlich leistungsorientiert gezüchtet. Das hat weltweit zu immer kürzeren Lebenszeiten und immer höheren Krankheitsanfälligkeiten der Tiere geführt, denn Gesundheitsmerkmale sind mit Produktionsmerkmalen negativ korreliert (LOTTHAMMER, 1999). Deshalb sind Zuchtverbände auf der ganzen Welt bestrebt, auch Gesundheitsmerkmale in die Zuchtwertschätzungen einzubeziehen. Für eine Zucht auf bessere Gesundheit wird neben der Erfassung von Krankheitsdaten der Tiere (v.a. in Skandinavien) nach einzelnen Hilfsmerkmalen wie Milchinhaltsstoffe, Exterieurmerkmale, Stoffwechselstabilität oder Fruchtbarkeitsdaten gesucht. Die Gesamtkonstitution der Tiere wird nur bei einer Zucht auf Lebensleistung (Haiger, 2001) wirklich...

Soil amendment with Pseudomonas fluorescens CHA0: lasting effects on soil biological properties in soils low in microbial biomass and activity
Provedor de dados: 21
Autores: Fliessbach, Andreas; Winkler, Manuel; Lutz, Matthias P.; Oberholzer, Hans-Rudolf; Mäder, Paul.
Pseudomonas fluorescens strains are used in agriculture as plant growth-promoting rhizobacteria (PGPR). Nontarget effects of released organisms should be analyzed prior to their large-scale use, and methods should be available to sensitively detect possible changes in the environments the organism is released to. According to ecological theory, microbial communities with a greater diversity should be less susceptible to disturbance by invading organisms. Based on this principle, we laid out a pot experiment with field-derived soils different in their microbial biomass and activity due to long-term management on similar parent geological material (loess). We investigated the survival of P. fluorescens CHA0 that carried a resistance toward rifampicin and the...

Mussels cultured on lines for nine months and harvested in March were boiled to remove shells and processed into a dry meal or a silage acidified by formic acid. Starfish meal was prepared from starfish caught in May, and a starfish juice fraction was obtained by pressing fresh starfish. Commercial fish silage from farmed salmon was also included in the experiment. The standardized ileal digestibility (SID) of crude protein (CP) and amino acids (AA) was evaluated in a Latin square design with pigs (initial weight 39.3 kg) fitted with a simple T-cannula in the terminal ileum. Diets contained 131–162 g CP/kg and 5 g chromic oxide/kg. Endogenous losses of protein and AA were estimated by feeding an N-free diet. On a dry matter (DM) basis, mussel meal...

In a long-term trial, the earthworm populations of two biological farming systems, two conventional systems and one control treatment were compared in a seven year crop rotation on a Luvisol from loess. The earthworms were investigated by handsorting at four dates during 1990-92. Nicodrilus longus (Ude), N. noctumus (Evans), N. caliginosus (Savigny) and Allolobophora rosea (Savigny) were the dominant earthworm species in all treatments. The earthworm biomass and density, the presence of anecic species, and the number of juveniles were significantly higher in the biological than in the conventional or unfertilized plots. In addition, more earthworm species were found in the biological plots. In this trial, plant protection management seems to be the main...

Resigning protein concentrates in dairy cattle nutrition:  a problemor a chance?
Provedor de dados: 21
Autores: Leiber, Florian.
Based on the assumption that the reduction of the use of imported protein concentrates, such as soybean from overseas, is a goal of ecologically sustainable livestock production, this paper is discussing significant aspects of dairy cows’ demand for dietary protein. These aspects are put in a general context of rumen fermentation efficiency. The main question is, whether new perspectives on optimal rumen functioning could be found, which allow to develop low-input feed evaluation systems for dairy cattle, especially in organic livestock systems. It is argued that besides the reduction in concentrated feedstuff, such systems should base on aspects of feeding behaviour and feed diversity. Such approaches are expected to avoid nutrition-based metabolic...

In economic terms, resilience in farming has to do with the capacity of a farm business to survive various risks and other shocks. Despite its importance, resilience has seldom been directly considered in evaluations of economic sustainability. A whole-farm stochastic simulation model over a 6-year planning horizon was used to analyse organic and conventional cropping systems using a model of a representative farm in Eastern Norway. The relative economic sustainability of alternative systems under  changing assumptions about future technology and price regimes was examined in terms of financial survival to the end of the planning period. The same alternatives were also compared in terms of stochastic efficiency. To model the risk of business failure...

The increasing global demand for chocolate and related products has intensified their production systems by both replacing traditional agroforestry systems with monocultures and increasing the use of synthetic external inputs and machinery. High dependence on non-renewable energy is a clear symptom of unsustainability in food production systems. Consequently, more sustainable agricultural practices should be promoted. With a special focus on non-renewable energy, this work compares: i) the cumulate energy demand (CED), ii) energy return on investment (EROI), and iii) energy return on labour of four different cacao production systems: two agroforestry systems and two monocultures under organic and conventional management.

Inter-row hoeing for weed control in organic spring cereals – interactions with inter-row spacing and nitrogen rate
Provedor de dados: 21
Autores: Melander, Bo.
Inter-row hoeing has become increasingly important for weed control in organic spring cereals since the introduction of automatic steering systems. The technology requires a widening of current inter-row spacing for spring cereals in order to provide sufficient room for accurate operation of a hoe share between crop rows. However, there is considerable uncertainty about the optimal combination of inter-row hoeing, inter-row spacing and nitrogen rate in terms of weeding effectiveness and crop yield. The aim of this study was to investigate the effect on weed and crop growth of the interaction between five inter-row spacings (125, 150, 200, 250, and 300 mm) and two nitrogen rates (50 and 100 kg NH4-N ha-1).

Public policies and organic farming
Provedor de dados: 21
Autores: GUYOMARD, H.
When markets fail, there may be justification for some market regulations by governments. There are at least four recognised causes of market failures that may call for government intervention in agriculture: negative and positive externalities (notably environmental externalities), public goods, insufficient information and market power (a few buyers or sellers are able to exert power on prices). This reading key of public economics is here used to analyse to what extent government intervention in organic farming is justified. We then examine various corrective steps that governments may take on the example of the French plan in favour of organic farming.

Life cycle assessment of fossil energy use and greenhouse gas emissions in Chinese pear production
Provedor de dados: 21
Autores: Liu , Y.; Langer, V.; Høgh-Jensen, H.; Egelyng, H.
An environmental life cycle assessment (LCA) was performed  in China to investigate environmental consequences of the life cycle of pears in terms of fossil energy use and greenhouse gas emissions. The assessment identified activities that contributed significantly to pears’ environmental impacts from the cradle to the point of sale. Cultivation was identified as having the greatest greenhouse gas emissions in pear production chains, followed by the process of storage and transportation. The contribution from fossil energy use differed in the production chains since environmental performance does not follow the farming system (organic-conventional) but is co-determined by topography and thus machine use, by market demands to seasonality of products and...

Cultivar differences in early spatial distribution of wheat, onion and lettuce roots
Provedor de dados: 21
Autores: Andresen, Marianne; Dresbøll, Dorte Bodin; Thorup-Kristensen, Kristian.
Organic plant production is generally dependent on import of plant nutrients from conventional farming 26 systems. With increasing focus on reducing the conventional import, increased nutrient use efficiency is an 27 aim in organic agricultural systems. One way to achieve this is by choosing nutrient efficient cultivars or by 28 breeding for such. It is especially in the plant establishment phase, that an efficient nutrient uptake is 29 important. At this stage, plants have limited root growth and thereby limited soil contact and nutrient 30 uptake. The possibility of the initial roots to exploit as large a volume as possible will therefore increase 31 nutrient uptake. In addition, in early spring nutrient levels in the soil are low as mineralization is...

In some cases, this model has afforded an opportunity to scale up from direct marketing by aggregating products from multiple producers and efficiently assembling and delivering them to large networks of consumers. Box schemes generally seek to attract consumers to their products based on the distinctive attributes and values associated with their food. This paper explores the spatial organization and the organizational dynamics of five multi-farm box schemes in relation to their stated values and marketing strategies using cases from Sweden, Denmark, Austria, and the United States.     Different aspects of ecological and...

O objetivo desse artigo é apresentar os resultados do levantamento dos agricultores familiares em processo de transição agroecológica no Território do Caparaó-ES, e discutir os fatores que afetam esse processo. O estudo revela o potencial dos sistemas agroecológicos para proporcionar maior sustentabilidade à produção familiar. Entretanto, os agricultores identificados enfrentam grandes dificuldades para desenvolverem este potencial, destacandose a falta de mais tecnologias e de assistência técnica com enfoque agroecológico, a falta de uma modalidade de crédito rural que atenda as exigências e peculiaridades do processo de transição e a falta de apoio à comercialização justa.

Short-term effects of tillage on mineralization of nitrogen and carbon in soil
Provedor de dados: 21
Autores: Kristensen, Hanne L.; Debosz, Kasia; McCarty, Greg W.
Tillage is known to decrease soil organic nitrogen (N) and carbon (C) pools with negative consequences for soil quality. This decrease is thought partly to be caused by exposure of protected organic matter to microbial degradation by the disturbance of soil structure. Little is known, however, about the short-term effects of tillage on mineralization of N and C, and microbial activity. We studied the short-term effects of two types of tillage (conventional plough- and a non-inverting-tillage) on mineralization and microbial N and C pools in a sandy loam under organic plough-tillage management. The release of active and protected (inactive) N by tillage was further studied in the laboratory by use of 15N labelling of the active pool of soil N followed by...

ENVIRONMENTAL POLICY PERFORMANCE REVISITED:  DESIGNING EFFECTIVE POLICIES FOR GREEN MARKETS
Provedor de dados: 21
Autores: Daugbjerg, Carsten; Sønderskov, Kim Mannemar.
Studies of environmental policy performance tend to concentrate on the impact of particular policy institutions or of single policy instruments. However, environmental policies most often consist of a package of policy instruments. Further, these studies pay no or very little attention to policy instruments directed at the demand-side of the market. Therefore this article develops a policy typology for government intervention aimed at creating green markets. The typology distinguishes between four types of policies based on the balance between supply-side and demand-side policy instruments applied. On the basis of the typology, a hypothesis on their ability to expand green markets is generated and tested in a comparative analysis of the performance of...

Maintaining or enhancing the stock of soil organic carbon (SOC) is a key factor in sustaining the soil resources of the world. The objective of this research was to study the effect of different farming systems (conventional farming with mineral fertilizers and crop specific fertilization vs. organic farming with organic fertilizers (catch crops and composted manure)) under the same 5-crop rotation (red clover, winter wheat, pea, potato, barley undersown with red clover) system on the SOC stock and the stability of SOC. The second aim was to quantify plant C inputs to the soil and to identify the relationship between C sequestration rate and C input. Data presented in this paper concerned the first rotation during 2008–2012. The main factors were farming...

Vom Aschenputtel zum Lieblingskind. Zur politischen Förderung des Ökolandbaus
Provedor de dados: 21
Autores: Dabbert, S.; Häring, A. M.
The rapid development of organic farming over the last decade is partly due to increased consideration of organic farming in policy measures. Examining this view, this article briefly discusses the current state and development of the organic farming sector and three lines of justification for policy support for organic farming: organic farming supplies public goods; the organic farming sector can be defined as an infant industry; and organic farming should be supported for risk precaution. Then, based on the observation that policy makers consider organic farming support justified, an integrated approach to organic farming policy is outlined.  from: Dabbert, S. und Häring, A. M.

Health of cows, calves and young stock on 26 organic dairy herds in Sweden
Provedor de dados: 21
Autores: Hamilton, C; Hansson, I; Ekman, T; Emanuelson, U; Forslund, K.
The health and housing of the stock on 26 organic dairy herds in four countries in eastern Sweden were studied for one year. The herds ranged in size from 12 to 64 cows, and their milk production from 3772 to 10,334 kg per cow per year. A large-animal practitioner visited the farms three times during the year, and a random sample of a third of the cows in each herd were examined. The calves and young stock and their housing were also studied. The calves were in good condition in all but four herds; their serum immunoglobulins varied from almost none to high levels. The young stock were in good condition and in good housing in 20 herds. No cows with clinical signs of metabolic disorders were found. Body condition scores were adequate or good except in two...

Organizações sociais e agroecologia: construção de identidades e transformações sociais.
Provedor de dados: 21
Autores: Bauer, Márcio André Leal; Mesquita, Zilá.
No presente trabalho, procuramos discutir as transformações ocorridas no espaço da agricultura familiar pós-Revolução Verde, especialmente a partir do movimento contestatório engendrado por organizações sociais que defendem o ideário agroecológico. Inicialmente, procurou-se compreender como a identidade a e realidade social são construídas e reconstruídas socialmente. Utilizou-se uma abordagem fenomenológica para investigar como se dá a ruptura com a realidade convencional e a transição para a agroecologia. Com base nas evidências empíricas, é possível dizer que a agroecologia participa da ressignificação positiva da identidade social dos agricultores. Entretanto, o reconhecimento da nova identidade passa pelo questionamento da realidade dominante a partir...

Feeding with chicory roots reduces the amount of odorous compounds in colon and rectal contents of pigs
Provedor de dados: 21
Autores: Jensen, M.T.; Hansen, L.L.
Sixteen pigs (eight entire males and eight females) were given individually two diets, control and control added 25% chopped chicory roots for 2 months before slaughter. Samples were taken from the contents in colon and rectum and subjected to GC-MS analysis for amount of odour impact compounds. The compounds 2-pentanone, ethylbutyrate,  propylpropionate, butyric acid, ethyl-2-methylbutyrate, p-cresol, indole and skatole showed a significant difference between the two treatments. The esters, which have relatively pleasant, often fruity odours, increased in the chicory treatment, whereas the malodorous compounds, p-cresol, indole and skatole decreased in the chicory treatment. The measured amounts of compounds were corrected for their odour thresholds as...

Manici, L. M., Kelderer, M., Caputo, F., Nicoletti, F., De Luca Picione, F. and Topp A. R. 2015.   Replant disease of fruit tree orchards has a multifactorial etiology, mainly due to the decline in soil biodiversity along with an increase in root rot pathogens, which can be principally countered with appropriate cropping practices. Therefore, a study on the impact of cover crops on plant health of young fruit trees in long-term orchards was performed. Bioassays were performed over two consecutive growing cycles using soil from a multigeneration apple orchard affected by replant disease. First, a cycle was performed with three cover crops (alfalfa, barley, marigold) and apple rootstock plantlets; at the end, the above-ground part of the plant was removed...

Autores: Weibel, Franco P.; Lemcke, B.; Monzelio, U.; Giordano, I.; Kloss, B.
With field trials over 3 years in a commercial organic orchard in Switzerland we have tested the efficacy of Armicarb® (potassium-bi-carbonate) for flower thinning in organic apple production. Over time, Armicarb was tested on 11 cultivars, at different application periods, in different concentrations, and always in comparison to other agents that are already allowed for thinning in organic fruit production in the European Union as e.g. lime sulphur, molasses, mechanical rope-thinner or combinations of methods. Armicarb proved to be an efficient and reliable thinning agent with an efficacy similar to the now recommended methods with rope device, molasses or lime sulphur but has the advantage to be an environmentally very friendly product. On the other...

It’s not always about growth! Development dynamics and management in food businesses and chains
Provedor de dados: 21
Autores: Münchhausen, von, Susanne; Häring, Anna Maria; Kvam, Gunn-Turid; Knickel, Karlheinz.
Growing small and medium enterprises face specific challenges, especially when they aim to maintain high quality products and processes. While growing, they tend to converge either towards niche markets or mainstream commodity markets, and as a result sacrifice higher quality and value. With this paper, we aim to show more about the growth processes of small and medium size enterprises and their related food supply chains. The focus is on the management of individual businesses, the coordination and cooperation along chains and the required realignment during growth. Particular attention is paid to discontinuities and an identification of the factors that limit or enable the sustainable development of food enterprises and chains. The methodological...

Effect of arbuscular mycorrhizal colonization and two levels of compost supply on nutrient uptake and flowering of pelargonium plants
Provedor de dados: 21
Autores: Perner, Henrike; Schwarz, Dietmar; Bruns, Christian; Mäder, Paul; George, Eckhard.
Two challenges frequently encountered in the production of ornamental plants in organic horticulture are: (1) the rate of mineralization of phosphorus (P) and nitrogen (N) from organic fertilizers can be too slow to meet the high nutrient demand of young plants, and (2) the exclusive use of peat as a substrate for pot-based plant culture is discouraged in organic production systems. In this situation, the use of beneficial soil microorganisms in combination with high quality compost substrates can contribute to adequate plant growth and flower development. In this study, we examined possible alternatives to highly soluble fertilizers and pure peat substrates using pelargonium (Pelargonium peltatum L’Her.) as a test plant. Plants were grown on a peat-based...

The roots of organic agriculture
Provedor de dados: 21
Autores: Paull, John.
It was concern about the replacement of traditional organic fertilizers by the then new chemical fertilizers that precipitated the early stirrings of disquiet about the prevailing direction of agriculture and which has grown into today’s organic agriculture movement. Unease about the issue of synthetic fertilizers preceded the current era of concerns about manufactured nanomaterials in food and farming, genetically modified organisms (GMOs), antibiotic-fattened farm animals, and synthetic pesticides. When Dr Rudolf Steiner was urged to give a series of lectures on agriculture at Koberwitz (now Kobierzyce, Poland) in 1924, those farmers were concerned about the encroachment of chemical fertilizers into their domain and their worries were that this was...

The use of desalinated-dried jellyfish and rice bran for controlling weeds and rice yield
Provedor de dados: 21
Autores: Hossain, Shaikh Tanveer; Sugimoto, Hideki; Asagi, N.; Araki, T.; Ueno, H.; Morokuma, M.; Kato, H.
To achieve higher rice production, rice-growing countries have used great amounts of synthetic chemical compounds (chemical fertilizers and pesticides) that can have adverse effects on the environment and humans. Organic products and organic farming technologies are friendlier to the environment and more conducive to sustainable agriculture but require different inputs, knowledge and skills. Weed control is one of the major challenges in organic rice cultivation. The present study proposes and tests the use of desalinated-dried jellyfish chips in the development of sustainable rice production. Vast amounts of jellyfishes have been found in the Sea of Japan (Nomura's jellyfish, Nemopilema nomurai Kishinouye) and Japan inland sea areas (Water jelly, Aurelia...

Autores: Molkentin, Joachim.
The carbon stable isotope ratio (δ13C) and the alpha-linolenic acid (C18:3ω3) content of milk fat were analyzed to examine their applicability as general markers for the authentication of organic retail milk in Germany. To record the variable effect of feeding, including the seasonal influence on milk composition, three conventionally and three organically produced brands of retail milk were collected biweekly during a period of 18 months. Altogether 286 milk samples were analyzed. Threshold values for the identification of German organic milk were established and allowed to delimit almost all conventional samples. Organic retail milk was always above a minimum C18:3ω3 content of 0.50% and below a maximum δ13C of -26.5‰. The universal and strongly negative...

The Challenges of Governing Urban Food Production across Four European City-Regions: Identity, Sustainability and Governance
Provedor de dados: 21
Autores: Reed, M.; Mettepenningen, E.; Swagemakers, P.; Dolores Dominguez Garcia, M.; Jahrl, I.; Koopmans, M. E.
The development of food production in cities has raised some important questions about the governance of these activities and the role of city-regions. In this paper through four European case studies– Bristol (UK), Ghent (Belgium), Vigo (Spain), and Zurich (Switzerland) –we consider the ways in which food is governed at the city level. Our case studies demonstrate the role played by citizens in urban food and the challenges this brings to city-region governance.

Arthropod food webs in organic and conventional wheat farming systems of an agricultural long-term experiment: a stable isotope approach
Provedor de dados: 21
Autores: Birkhofer, K.; Fließbach, A.; Wise, D.H.; Scheu, S.
1 Agricultural intensification not only alters the structure of arthropod communities, but also may affect biotic interactions by altering the availability of basal resources. We analyzed variations in stable isotope ratios (15N/14N and 13C/12C) of fertilizers, plants, prey and generalist predators in organic and conventional farming systems in a long-term agricultural experiment [DOK trial (bioDynamic, bioOrganic, Konventionell)]. Two basal resources with pronounced differences in carbon isotope signatures, wheat litter (C3 plant) and maize litter (C4 plant), were used to uncover differences in food web properties between the two farming systems (conventional versus organic).  2 Predators incorporated significantly higher proportions of carbon from wheat...

Nutrient supply to organic agriculture as governed by EU regulations and standards in six European countries
Provedor de dados: 21
Autores: Loes, A-K.; Bünemann, E.; Cooper, J.; Hörtenhuber, S.; Magid, J.; Oberson, A.; Möller, K.
Organic farming systems need to replace nutrients exported via farm products, especially phosphorus (P) which may otherwise become depleted in soil in the long term. In Europe, EU regulations for organic production are shaping the farming systems with respect to inputs of nutrients. Permitted off-farm P sources include conventional animal manure, composted or anaerobically digested organic residues, rock phosphate, and some animal residues such as meat and bone meal. The recent proposed revision of EU regulations for organic production (2014) puts less emphasis on closing nutrient cycles and instead aims at minimizing off-farm inputs, to reduce the risk of importing contaminants. This development, which has received little attention from the organic sector...

Input output accounting systems in the European community - an appraisal of their usefulness in raising awareness of environmental problems
Provedor de dados: 21
Autores: Goodlass, G.; Halberg, N.; Verschuur, G.
Input Output Accountingsystems (IOAs) can be used to identify farming practices which are not ‘environmentally neutral’ and thus unlikely to be sustainable in the long term. In an EU sponsored project, European countries were surveyed and over 50 farm level IOAs identified. The subjects covered by the IOAs included nutrients, pesticides, energy, soil/habitat, conservation, wastes (e.g.packagingandtyres)and other items such as veterinary products. Nearly half the IOAs covered more than one subject and nutrient budgets were the most commonly included(91% of the IOAs studied). Looking at the 30 single subject systems, most (26)were nutrients with only three pesticide and one energy based system. In total 50 systems covered nutrients. Overall, where specified,...

In France Fruit production is cultivated on 140 thousand hectares, mainly conducted on intensive training system. Very few elements are available on low input training systems while they have to integrate the Global rule under the frame of Ecophyto 2018. In order to evaluate if another system of cultivation will be possible, a project has been developed to highlight the main factors to be integrated in low input training system. A low input multilocal experimental design has thus been investigated on apricot in two main regions of production: Rhone valley and Roussillon. A set of 9 common cultivars with 20 replications each, planted in a complete single-tree randomization design has been established.  As already observed in apple orchard, a larger set of...

Effect of seed rate and row spacing in seed production of Festulolium
Provedor de dados: 21
Autores: Deleuran, L.C.; Gislum, R.; Boelt, B.
Establishment methods have proven to be of major importance for grass seed production. The objective of this research was to test the effect of different sowing techniques on plant establishment and the subsequent seed yield. Perennial ryegrass (Lolium perenne L.) is used as the model grass due to its large importance in Danish agriculture.  In a three-year trial six different methods of under-sowing of perennial ryegrass in a spring barley cover crop were employed. Perennial ryegrass was either sown directly at different depths within the spring barley (Hordeum vulgare L.) rows or placed 2, 6 or 12 cm from the spring barley rows. Results of dry matter yield indicate that the best establishment of the grass occurred when placing the grass 6 or 12 cm from...

Consumers’ evaluation of imported organic food products: The role of geographical distance
Provedor de dados: 21
Autores: Pedersen, Susanne; Aschemann-Witzel, Jessica; Thøgersen, John.
Country-of-origin (COO) effects and consumer evaluation of organic food products are rarely studied in combination. The aim of this study was therefore to investigate organic consumers’ preferences for imported organic food products from different origins and the underlying reasons for these preferences, including how consumers’ COO preferences depend on the geographical distance to the COO. We employed a multi-method, qualitative approach consisting of in-store interviews (N = 255) and focus groups (six, N = 38) with organic consumers in three German cities located in the north (Hamburg, close to Denmark), west (Münster, close to The Netherlands) and south (Munich, close to Austria). The interviews confirmed the well-known preference for domestic (also...

Linking species traits to agroecosystem services: a functional analysis of weed communities
Provedor de dados: 21
Autores: Bàrberi, P.; Bocci, G.; Carlesi, S.; Armengot, L.; Blanco-Moreno, J.M.; Sans, F. X.
There is a growing interest in the use of functional approaches for the study of weed assemblages, to disentangle underlying processes determining their composition and dynamics. Functional approaches are based on the assumption that weed community composition and dynamics can be best explained by a set of species traits expressing their response to agricultural disturbance. This knowledge should help develop more sustainable, ecologically based weed management systems. Trait‐based data required for this kind of analysis are available from various sources, but most of them either cover mainly non‐weedy species or, in the case of weed‐focussed trait databases, they cover a limited number of species. In this work, we present a trait database for 240 weed...

Elytrigia repens population dynamics under different management schemes in organic cropping systems on coarse sand
Provedor de dados: 21
Autores: Rasmussen, Ilse A.; Melander, Bo; Askegaard, Margrethe; Kristensen, Kristian; Olesen, Jørgen E.
Elytrigia repens is a rhizomatous perennial weed prevalent in organic cropping systems in Scandinavia. This study analysed the population dynamics of E. repens in a long-term crop rotation experiment on coarse sand in Denmark in order to gain insights into the factors influencing its population changes, especially those important for outbreaks of E. repens infestations. Data were obtained from three cycles of four-year crop rotations with various cash crops and annual grass-clover subjected to four treatment combinations: with and without animal manure and with and without catch crops. E. repens was controlled by different tillage and mowing strategies between and within crops. Pulses and spring cereals caused the highest population increases, especially...

Residual effect and nitrate leaching in grass-arable rotations: Effect of grassland proportion, sward type and fertilizer history
Provedor de dados: 21
Autores: Eriksen, J.; Askegaard, M.; Søegaard, K.
A key point in designing grass-arable rotations is to find the right balance between number of cultivations versus the length of the grass phase. In a field experiment, we investigated the effect of cropping history (grazed grass-clover and ryegrass, proportion of grassland and previous fertilizer use) on crop growth and nitrate leaching in two years following grassland cultivation. In the final year, the effect of perennial ryegrass as a catch crop was investigated. The nitrogen fertiliser replacement value (NFRV) of grassland cultivation was higher at 132 kg N ha-1 in the rotation with 75% grassland compared to on average 111 kg N ha-1 in rotations with 25 and 38% grassland and the NFRV of ryegrass in the rotation was higher than that of grass-clover....

Provedor de dados: 21
Autores: Adamsen, Christina E.; Hansen, Mette L.; Møller, Jens K.S.; Skibsted, Leif H.
Aqueous phosphate buffer extracts and acetone/water extracts of pigments from Parma ham were assessed as antioxidants by (1) electron spin resonance spectroscopy using a spin probing technique to evaluate their efficiencies as scavengers of free radicals, and (2) by electrochemical measurement of oxygen depletion rate in an aqueous methyl linoleate emulsion to evaluate their efficiencies as chain-breaking antioxidant, and using both methods, compared with the effect of apomyoglobin and nitrosylmyoglobin. Aqueous phosphate extracts and acetone/water extracts of Parma ham pigment both scavenged a semi-stable nitroxide radical (Fremy's salt), and both extracts reduced the rate of oxygen consumption for lipid peroxidation (initiated by metmyoglobin) very...

Freqüentemente recorre-se à ciência para legitimar a prioridade atribuída ao desenvolvimento de sementes transgênicas na pesquisa agronômica, e a proteção privilegiada concedida aos direitos de propriedade intelectual sobre tais sementes. Alega-se que as sementes transgênicas incorporam conhecimento científico, mas não as sementes selecionadas na agricultura tradicional; e que o conhecimento científico sustenta não haver, além da agricultura que faz uso substancial de sementes transgênicas, maneira alternativa nenhuma de alimentar a humanidade. Ambas as alegações são questionadas por meio de um argumento que reconhece na agroecologia uma séria alternativa (pelo menos parcialmente) à predominância da biotecnologia na agricultura,uma alternativa que não...

In den ersten drei Jahren hat der seit 2002 laufende Langzeitversuch Frick (Schweiz) bereits viele spannende Ergebnisse zu Tage gefördert. Unerwartet war, dass Weizen, der in Parzellen gewachsen war, welche lediglich im Versuchsjahr mit biologisch-dynamischen Präparaten behandelt wurden, weniger Fusarientoxine enthielt und mit den bildschaffenden  Methoden klar von nicht behandelten Weizenproben unterschieden werden konnte.    Sehr bedeutsam sind auch die Ergebnisse zur Bodenfruchtbarkeit: Reduziert bearbeitete Böden waren schon nach kurzer Zeit belebter, wiesen etwas mehr Humus auf und auch die Symbiosepilze fühlten sich dort wohler als in gepflügten Böden.

Quality characteristics of edible linseed oil
Provedor de dados: 21
Autores: Nykter, Minna; Kymäläinen, Hanna-Riitta; Gates, Fred; Sjöberg, Anna-Maija.
In this review the quality properties of linseed oil for food uses are discussed as well as factors affecting this quality. Linseed oil has a favourable fatty acid composition with a high linolenic acid content. Linseed oil contains nearly 60% á-linolenic acid, compared with 25% for plant oils generally. The content of linolenic acid and omega-3 fatty acids is reported to be high in linseed grown in northern latitudes. The composition of fatty acids, especially unsaturated fatty acids, reported in different studies varies considerably for linseed oil. This variation depends mainly on differences in the examined varieties and industrial processing treatments. The fatty acid composition leads also to some problems, rancidity probably being the most...

Categorisation of dairy production systems: A strategy for targeting meaningful development of the systems in Uganda
Provedor de dados: 21
Autores: Mubiru, S.L.; Tenywa, J.S.; Halberg, N.; Romney, D.; Nanyeenya, W.; Baltenweck, I.; Stall, S.
Dairy production is a major contributor towards national economies and household food security and incomes in sub-Saharan Africa (SSA). Milk production in the region is estimated at 1.27 million metric tonnes year-1. However, this level of milk production is inadequate for the existing human population who would require 103 million metric tonnes year-1. In Uganda, milk production only meets approximately 20% of the population's nutritional requirements. As such, methods need to be sought to increase milk production in the region.     Research efforts have made strides in identifying the causes of the production-demand gap in the SSA region and a spectrum of interventions to bolster the productivity. Unfortunately, these efforts have by far yielded...

Opportunities and Barriers for Niche Marketing of Lamb in European LFAs  based on Consumer Attitudes to Product Quality
Provedor de dados: 21
Autores: Rahmann, Gerold; Ashworth, Stuart; Boutonnet, Jean-Paul; Brunori, Gianluca; Papadopoulus, Ilias.
With commodity prices continuing to decrease and with policy constraint that farmers  cannot easily increase their incomes by increasing volumes of production, they must  find alternative ways to maintain their standard of living. This can be achieved by  either niche marketing of agricultural products or by environmental payments, which  are either paid by the government or the consumer.  The results of a consumer survey carried out in Less Favoured Areas in Scotland,  Germany, Greece, France and Italy to assess consumer attitudes of what constitutes  the quality of lamb and the extent to which this provides an opportunity to exploit  niche marketing, are discussed. Consumers generally have much less interest in the  use of regional labelling,...

Autores: COQUIL, X.; TROMMENSCHLAGER, J-M.; BAZARD, C.; DESPRES, S.; DELABY, L.
We compared the use of three farm grown cereal/protein mixes (oat/fava bean, barley/lupin, triticale/pea), that were used to complement lactating dairy cow diets based on hay consisting of alfalfa/orchard grass and perennial grassland. The trial took place in 2007 at the INRA experimental station of Mirecourt, where an organic mixed-crop dairy system is being prototyped. The experiment was carried out in a Latin square with three groups of eight cows (50% Holstein, 50% Montbéliarde). The cows were fed 4 kg/cow/day of one of the three cereal/protein mixes, 8 kg DM/cow/day of alfalfa/orchardgrass hay, and permanent grassland hay ad libitum. The three diets were indicative of the animals’ needs. Diets had no significant effect on milk production (20.3...

Auch für den Ökolandbau wurden die Ziele mit der Umsetzung der EWG-VO 2092/91 und der darin enthaltenen Richtlinie zur Tierhaltung (EG-VO 1804/99) neu definiert. Die Tiergesundheit soll vor allem durch Vorsorge, Auswahl geeigneter Rassen, Fütterung und Umweltbedingungen sowie angepasster Leistungsniveaus gewährleistet werden.

Threshold levels for seed borne diseases in organic cereals
Provedor de dados: 21
Autores: Nielsen, Bent J.
Seed borne diseases can cause serious problems in organic seed production where there is no control methods implemented in practice. Current practice in organic agriculture is to analyse the seed and to discard the seed lot if the infection by diseases exceeds the threshold levels.   There is no tolerance list specific for organic agriculture. In Denmark we use the same threshold values as recommended in conventional agriculture for seed treatment.

Raps – die Königsdisziplin im Bioackerbau
Provedor de dados: 21
Autores: Daniel, C.; Dierauer, H.; Schärer, F.; Ramseier, H.; Bovigny, C.; Jossi, W.; Humphrys, C.
Der Rapsanbau ist risikobehaftet, aber durchaus interessant: Es lässt sich ein ähnlich hoher Deckungsbeitrag erwirtschaften wie mit Weizen. Und die Nachfrage nach kalt gepresstem Biorapsöl übersteigt das Angebot deutlich. Gute Zeiten für Einsteigerinnen und Einsteiger die sich – gut vorbereitet – an die «Königsdisziplin» des Bioackerbaus wagen wollen.  Die Anbaufläche von Bioraps in der Schweiz konnte seit dem Jahr 2000 von 5 auf 150 Hektaren gesteigert werden. Eine Erfolgsgeschichte mit Fortsetzung: Die Biofarm Genossenschaft sucht weitere Produzenten, um die anhaltend grosse Nachfrage nach kalt gepresstem Biorapsöl zu decken.

Hyperspectral imaging for the determination of potato slice moisture content and chromaticity during the convective hot air drying process
Provedor de dados: 21
Autores: Amjad, Waseem; Crichton, Stuart O.J.; Munir, Anjum; Hensel, Oliver; Sturm, Barbara.
Hyperspectral imaging (HSI) was utilised for the determination of moisture content of potato slices with three thicknesses (5 mm, 7 mm, 9 mm) at three drying temperatures (50 °C, 60 °C, 70 °C) during convective drying in a laboratory hot air dryer. The Page, thin-layer drying model was found better to explain the drying kinetics with a fitting accuracy of R2 (0.96–0.99) and lowest reduced Chi-square (0.00024–0.00090), Root mean square errors (RMSE) (0.014–0.026), and relative percentage error (1.5%–5.1%) under the used drying conditions. Spectral data were analysed using partial least squares regression (PLS) analysis, a multivariate calibration technique, alongside Monte Carlo Uninformative Variable Elimination (MCUVE-PLS) and competitive adaptive...

Enhancing agroecological innovations with a multi-level approach to experimental research needs
Provedor de dados: 21
Autores: LE PICHON, V.; Filleron, Emmanuelle; Ricavy, I.; Taussig, C.; Bellon, Stéphane.
Public policies clearly aim at an ecologisation of agriculture. However, few concrete goals or incentives have been established to mobilize the experimental research. Applied to 13-year results of four experimental stations of the South-East of France, the Direct-Indirect-System multi-level analysis grid showed a diversification of their experimental strategies. These three levels of analysis, combined with the identification of different types of agroecosystems, appears as promising for instigating assessment and determining agroecological innovation priorities for an experimental station, a territory or a food chain.

Nitrogen (N) utilisation by crops has to be improved to minimize losses to the environment. We investigated N use efficiency of animal manure and mineral fertiliser and fate of fertiliser N not taken up by crops in a conventional (CONMIN) and a bioorganic (BIOORG) cropping system of a long-term field experiment over three vegetation periods (winter wheat–soybean–maize). Microplots planted with wheat received a single application of 15N-labelled slurries (either urine or faeces labelled) or mineral fertiliser. At the end of each vegetation period we tested whether higher microbial activity and larger microbial biomass in BIOORG than CONMIN soils, and lower long-term N input level in BIOORG, affected use efficiency and fate of fertiliser N not taken up by...

Human urin indeholder mange værdifulde næringsstoffer. I stedet for at oprense næringsstofferne fra spildevandet, kan urin med fordel tilbageføres til landbruget som organisk gødning. Samtidig ville man mindske østrogenbelastningen til de meget sårbare vandmiljøer. Men hvordan vil østrogenbelastningen i jord være ved brug af human urin i forhold til almindelige organiske gødninger?

Managing the necessary cross-disciplinary approach to organic farming research programmes: example of an organic bread programme.
Provedor de dados: 21
Autores: VIAUX, P.; TAUPIER-LETAGE, B.; ABECASSIS, J.
This programme was developed within a cross-disciplinary approach resulting from five project proposals focusing on the organic wheat, flour and bread sector. More than 30 researchers from nine academic research laboratories, five technical centres, three development agencies and four industrial firms were involved in the project, covering a large area of expertise (from genetics to sociology). The programme adopted a reverse engineering approach, starting from consumer expectations and travelling, link-by-link, up the food chain. A qualitative study of consumer perception and expectations showed that organic bread was perceived as a natural, nourishing and healthy product, and that although its organoleptic characteristics (volume, texture, etc.) were a...

Agricultura em zonas ripárias do sul do Brasil: conflitos de uso da terra e impactos nos recursos hídricos.
Provedor de dados: 21
Autores: Martini, Luiz Carlos Pittol; Trentini, Élen Cristin.
O trabalho apresenta e discute a questão da proteção de zonas ripárias em áreas agrícolas do Sul do Brasil, em especial no Estado de Santa Catarina, em que predomina agricultura familiar praticada em pequenas propriedades. As exigências legais determinadas pelo Código Florestal brasileiro de 1965 são apresentadas frente às limitações para atendimento da lei impostas por fatores culturais, do meio físico e do tamanho das propriedades agrícolas. Para ilustração do problema, são confrontadas as duas correntes preponderantes no debate a respeito da utilização de áreas ripárias em Santa Catarina: aplicação dos dispositivos legais existentes versus flexibilização da lei para atender usos atuais em áreas de preservação permanente.

Population varieties can meet the needs of organic farming as they are composed of diverse genotypes and have nutritional and sensory characteristics of interest. Their intra-specific genetic variability helps to adapt to the diversity of soil and climate conditions, management practices and needs. Moreover, an integrated organic bread sector has emerged willing to use more wheat populations. To explore sensory and nutritional potential of bread wheat populations, hedonic tests, sensory profile and nutritional analyses were implemented on eight wheat population varieties and one modern variety. Hedonic tests revealed consensus among consumer when ranking according to specific sensory characteristics and showed preferences for red wheat breads. Descriptive...

Heard health management in organic pig production using a quality assurance system based on Hazard Analysis and Critical Control Points
Provedor de dados: 21
Autores: Bonde, M.; Sorensen, J.T.
Health and welfare problems in organic pig production may differ form problems in conventinal pig herds as a result of differences in management. Control of animal health problems in organic herds is affected by the restrictions in medicine use and prophylactic medication as well as by the risk of wildlife contact and difficulties in cleaning and and disinfectin imposed by the access to outdoor areas. To monitor risk factors for diseases and to control these risk factors as a means to prevent diseases, we suggest the implementation of health management based on Hazard Analysis Critical Control Point (the HACCP concept). The development of a HACCP system requires the quantification of risk factors by means of epidemiological studies of alternatively by an...

Autores: Jensen, Maja M.; Jørgensen, Henry; Halekoh, Ulrich; Watzl, Bernhard; Thorup-Kristensen, Kristian; Lauridsen, Charlotte.
BACKGROUND:  Organic food is perceived as being of better quality and healthier than conventional foods although the scientific research on organic foodstuffs is highly contradictory. The aim of the present study was to investigate if an intake of carrots from four different cultivation systems grown in two consecutive years would influence various biomarkers of health in a rat model. All rats were fed a diet with 40% carrot content. The carrots were grown under conventional (C), “minimalistic” organic (O1), organic (O2), or “very” organic cultivation systems (O3). A control group (CO) being fed standard rat chow was included. RESULTS: The plasma α-tocopherol concentration was higher in the O2 carrot-based diet than in the C carrot based-diet in one year,...

Auxin-mediated relationships between apple plants and root  inhabiting fungi: impact on root pathogens and potentialities  of growth-promoting populations.
Provedor de dados: 21
Autores: Manici, L.; Kelderer, M.; Caputo, F.; Mazzola, M.
This study aimed to elucidate the relationship between plant hosts and root-colonizing fungi recovered from apple orchard soils that had been replanted over multiple generations. Functional relationships of three groups of filamentous fungi (Ceratobasidium sp., Cylindrocarpon-like group and Fusarium acuminatum) with apple rootstocks were evaluated  in plant growth bioassays. The Cylindrocarpon-like group and Ceratobasidium sp. showed a relationship with the host plant varying from pathogenic to commensal through to mutualistic for the latter group, while that of F. acuminatum tended to be mutualistic. Seven fungal isolates of each group, which induced the highest plant growth in bioassays, were evaluated for auxin (IAA) and gibberellin (GA3 and GA4)...

Airborne biological hazards in different pig fattening systems
Provedor de dados: 21
Autores: Diefenbach, H.; Hartung, E.; Sundrum, A.; Lohmeyer, M.; Rieger, M.A.
In this research project two organic and two conventional housing systems for fattening pigs are assessed in regard to the emission of microorganisms, endotoxins and dust. The concentrations of microorganisms and endotoxins varied between the different housing systems while no distinct differences for the dust concentrations were observed. Endotoxins concentrations reached up to 14 495 EU/m³ (median) in deep litter stable, indicating the high exposure with biological agents during farm work. The differences between the stables could not be assigned to the organic or conventional kind of husbandry but to the management of the systems.  Copyright © by BIOLIFE, s.a.s.

Gastrointestinal helminths in calves and cows  in an organic milk production system
Provedor de dados: 21
Autores: da Silva, Jenevaldo Barbosa; Rangel, Charles Passos; da Fonseca, Adivaldo Henrique; Soares, João Paulo Guimarães.
The main aim of this study was to determine the distribution of populations of gastrointestinal helminths in lactating crossbred cows and calves during the grazing season in an organic milk production system. In addition, the potential importance of the peripartum in relation to the parasite load was examined. Between January 2007 and December 2008, parasitological fecal examinations were performed on cattle belonging to the Integrated Animal Production Program of Embrapa Agrobiology. The cows' parasite load remained low during the study period, and there were no statistical differences (p &gt; 0.05) in comparisons between the seasons. The average egg count showed a positive correlation (0.80) with the peripartum, such that egg elimination per gram (p &lt;...

Das Ziel der Untersuchungen war nachzuweisen, ob unterschiedliche Aufzuchtmethoden – konventionelle und ökologische – Qualitätsunterschiede erzeugen, die mit physikalischen Methoden wie z. B. Farbmessungen und Dynamischer Differenz-Kalorimetrie (DDK) erkennbar sind. Die Farbmessungen enthüllten bemerkenswerte Helligkeitsunterschiede. Geräucherte Forellen aus konventioneller Zucht waren deutlich heller als Forellen aus ökologischer Zucht. Dieser Unterschied von L* konnte schon am Rohmaterial festgestellt werden. Bei Kühllagerung glichen sich die Unterschiede jedoch aus. Die Rot- und Gelbwerte wurden nicht signiﬁkant von der Aufzuchtmethode beeinﬂusst und änderten sich auch nicht wesentlich während der Kühllagerung. Auf der Grundlage früherer Untersuchungen...

Germination: a means to improve the functionality of oat
Provedor de dados: 21
Autores: Kaukovirta-Norja, Anu; Wilhelmson, Annika; Poutanen, Kaisa.
The biochemical and physiological reactions of germination have long been utilised to produce barley malt for brewing and other purposes. Also some oat malt has been produced as raw-material of ale and stout production. The main goals of malting have been the degradation of grain storage components to soften the kernel structure, synthesis of amylolytic enzymes and production of nutrients for brewing yeast. Also flavour and colour attributes have been important. During the recent years interest has arisen also in the secondary metabolites produced during germination, which can have valuable health promoting properties and act as bioactive or functional compounds in foods. By using a tailored germination/malting process a desired combination of valuable...

Pflanzliche Dünger zur Stickstoffversorgung einer Tomatenkultur im Folientunnel im Ökologischen Landbau
Provedor de dados: 21
Autores: Rührer, Judith; Friedel, Jürgen K.; Freyer, Bernhard.
Die Nachfrage nach Obst und Gemüse aus Ökologischem Anbau hat nach Angaben der Zentralen Markt- und Preisberichtstelle (BRD) 2001um rund 50% zugenommen. Als eines der beliebtesten Bio-Gemüse gilt die Tomate (Lycopersicon lycopersicum). Die Tomatenkulturen stellen aufgrund ihrer langen Vegetationsdauer (25 Wochen) hohe Ansprüche an die Versorgung mit Stickstoff (N). Seit die meisten tierischen Eiweißdünger im Jahr 2001 verboten wurden (seit kurzem sind viele wieder erlaubt), wird aufgrund geringer Erfahrungen mit Stickstoffdüngern, die dem System des Ökologischen Landbaus entsprechen,  zunehmend das industrielle Nebenprodukt Vinasse als systemfremder und schnellverfügbarer  N-Dünger verwendet.Da es kaum Untersuchungen zum Einsatz pflanzlicher...

Energy self-reliance, net-energy production and GHG emissions in Danish organic cash crop farms
Provedor de dados: 21
Autores: Halberg, N.; Dalgaard, R.; Olesen, J.E.; Dalgaard, T.
Organicfarming(OF)principles include the idea of reducing dependence of fossil fuels, but little has been achieved on this objective so far in Danish OF. Energy use and green house gas (GHG)emissions from anaverage 39 ha cash crop farm were calculated and alternative crop rotations for bio-energy production were modeled. Growing rape seed on 10% of the land could produce bio-diesel to replace 50–60% of the tractor diesel used on the farm. Increasing grass-clover area to 20% of the land and using half of this yield for biogas production could change the cash crop farm to an etenergy producer, and reduce GHG emissions while reducing the overall output of products only marginally. Increasing grass-clover area would improve the nutrient management on the farm...

Climate Change, Agriculture and Development in Croatia
Provedor de dados: 21
Autores: Legro, Susan; Znaor, Darko; Landau, Seth.
Both the challenges and potential benefits of climate change mitigation and adaptation are particularly apparent in Croatia's agricultural sector. In 2004, this sector emitted 3.558 Gg of CO2 equivalent, comprising 12 percent of the country’s anthropogenic GHG emissions in that year. Soil management accounted for 62 percent of these emissions, enteric fermentation (associated with animal digestive systems) accounted for 25 percent, and manure management for 13 percent. However, recent research suggests that the GHG emissions generated by Croatian agriculture and related activities (e.g., energy, farm-inputs, trade, transport, agricultural research, veterinary services) are responsible for 18 percent of all anthropogenic GHG emissions in Croatia.

Autores: Titze, Andreas; Jakobs, Marion.
The influence of different fertilization (NPK, PK, 0) and cutting frequency (2, 4 or 6 cuts) on dry matter yield, feeding value and plant composition of the sward of fen soil permanent grassland was investigated over five years. A randomizedblock design with plots was used, with three blocks. Effect of N application (NPK with 140 kg N/ha per year) was very low, because of a high N-mineralisation rate in the fen soil. Under intensive management (4 or 6 cuts) the PK-treatment (without N) reached a high feeding value as well as a high dry matter yield. This result may be very important for organic grassland farming on fen soils. Deficiencies in soil nutrients (0-treatment), especially potassium, reduce dry matter yield, high quality forage plants content of...

Provedor de dados: 21
Autores: Kristensen, T.; Thamsborg, S.M.; Andersen, H.R.; Søegaard, K.; Nielsen, L.
Production and endoparasitism in first grazing season of Holstein heifers and steers were investigated in two grazing seasons, at low-lying peaty soil. In year 2000, forty animals were included in a 2 x 2 factorial, replicated experiment with two sexes (steers vs. heifers) and two stocking rates (SR): normal vs. low (840 vs. 420 kg live weight per ha at turn out) in a set stocking grazing system. Mean grass height over the entire season were 6.3 ± 4.8 cm (mean ± s.d.) at normal SR and 9.8 ± 6.1 cm at low SR. Mean daily live weight gain during grazing was significantly (P &lt; 0.001) lower at normal SR (256 ± 147 g) compared to low (468 ± 142 g) but sex did not significantly affect the daily gain.

Este artigo analisa o processo de conversão para a olericultura orgânica por meio de estudos de caso junto a agricultores com comercialização em supermercados ou feiras específicas, constatando que o Estado sempre esteve à margem do processo de difusão da agricultura orgânica, determinando o estabelecimento de uma cultura de “independência” por parte desse setor produtivo. Pelo fato de a produção de hortaliças exigir um contato constante com o mercado e o processo de inovação tecnológica, há uma baixa demanda de apoio por parte pelos agricultores, independentemente do estrato socioeconômico. O artigo mostra também que ações públicas destinadas a promover a conversão para sistemas orgânicos têm maior receptividade junto a produtores familiares, em função da...

Since January 2008 the ration for organic herds has been required to be 100% organic (Regulation No. 889/2008). However, this may not satisfy the high energy demands of early lactation cows. We thus investigated the possible effects of 100% organic feed on the energy balance in Swedish organic dairy herds as indicated by the following blood parameters (n = 739 observations): Beta-hydroxybutyrate (BHBA), non-esterified fatty acid (NEFA) and insulin, and the occurrence of clinical ketosis (n = 8769 observations). Thirteen organic and 13 conventional herds were visited and blood samples from 81 cows around parturition ( &gt;= 3 cows per herd) were used. The metabolic status of the same herds under the previous rules was available for comparison. The BHBA,...

N use efficiencies and N2O emissions in two contrasting, biochar amended soils under winter wheat-cover crop-sorghum rotation
Provedor de dados: 21
Autores: Hüppi, Roman; Neftel, Albrecht; Lehmann, Moritz F.; Krauss, Maike; Six, Johan; Leifeld, Jens.
Biochar, a carbon-rich, porous pyrolysis product of organic residues, is evaluated as an option to tackle major problems of the global food system. Applied to soil, biochar can sequester carbon and have beneficial effects on nitrogen (N) cycling, thereby enhancing crop yields and reducing nitrous oxide (N2O) emissions. There is little understanding of the underlying mechanisms, but many experiments indicated increased yields and manifold changes in N transformation, suggesting an increase in N use efficiency. Biochar's effects can be positive in extensively managed tropical agriculture, however less is known about its use in temperate soils with intensive fertilisation. We tested the effect of slow pyrolysis wood chip biochar on N use efficiency, crop...

Vorblütebehandlungen mit Kaolin gegen den Gemeinen Birnenblattsauger (Cacopsylla pyri)
Provedor de dados: 21
Autores: Daniel, Claudia; Wyss, Eric.
The European pear sucker Cacopsylla pyri (L.) (Homoptera: Psyllidae) – one of the main pest insects in pear production – is commonly controlled by spraying broad-spectrum insecticides, which may have serious side-effects on beneficial arthropods. Recently, a new approach to fruit pest management has arisen in the form of processed-kaolin particle film technology (product name Surround® WP). The white kaolin particle film repels insects without killing them. Therefore, side effects on beneficial arthropods are expected to be low. This new approach triggered the present study to control C. pyri. In spring 2003 a small-plot field trial was conducted to assess the impact of pre-flowering kaolin treatments on the first generation of C. pyri. Multiple...

Autores: Pommeresche, Reidun.
This study focusses on the spider fauna in two organically managed leys in different stages of a crop rotation and in one permanent pasture, all on the Tingvoll Farm in northwestern Norway. Spiders were collected by means of pitfall traps; the sampling period lasted from 28 April to 23 June 2000. Altogether 2415 specimens, representing 48 species, were found. A DCA-analysis shows differences in the spider populations found in the leys compared with the pasture, but less difference between the young and older ley. However, the number of species and the dominance pattern of the spider populations differ between the young and older ley. A total of 16 species were found in the young ley, 26 species in the older ley and 34 species in the pasture. Bathyphantes...

Compared with the soil from the recently established pasture, an increase of total soil C and N was observed along with pasture age. Greenhouse gas emissions were low and not significantly different among the soils from younger pastures (0–5 years), but especially N2O emissions increased markedly in the soil from 16-year-old grass–clover. Low emissions might mainly be due to an early C limitation occurring in the soils from younger pastures, which was also corroborated by   decreasing levels of...

Der ökologische Fußabdruck: biologische Mutterkuh- und konventionelle Mastrinderhaltung im Vergleich
Provedor de dados: 21
Autores: Kratochvil, Dr. Ruth; Dekker, Sanne.
Der ökologische Fußabdruck ist ein Werkzeug, um den anthropogenen Naturverbrauch vor dem Hintergrund einer nachhaltigen Entwicklung zu bilanzieren. Im vorliegenden Artikel wurde der ÖFA für Rindfleisch aus ökologischer Mutterkuh- und konventioneller Mastrinderhaltung berechnet. Bedingt durch extensive Grünlandbewirtschaftung, höheren Stallgebäude- und Strohbedarf sowie niedrigere tierische Leistungen ist der ÖFA für Rindfleisch aus Mutterkuhhaltung fünf Mal so hoch wie jener für Rindfleisch aus konventioneller Mastrinderhaltung. Im Ökologischen Landbau wird somit die Qualität des Produktionssystems mit einer höheren Quantität an direktem Flächenverbrauch sichergestellt. Die mangelnde Berücksichtigung qualitativer Aspekte stellt somit die Anwendbarkeit des...

Molecular markers to exploit genotype-environment interactions of relevance in organic growing systems
Provedor de dados: 21
Autores: Backes, Gunter; Østergard, Hanne.
One of the substantial differences between conventional and organic growing systems is the degree to which the farmer can control biotic and abiotic stresses; for organic growing systems varieties are needed with a broad adaptation to annually varying factors, while at the same time a good specific adaptation is necessary with respect to more constant climate and soil conditions. This combination of requirements implies that varieties for organic farming need to be better characterised with respect to genotype x environment interactions than varieties for conventional farming. Such interactions, which often are found for quantitatively expressed traits, are in general difficult to deal with in phenotypic selection. New approaches for QTL analyses (e.g....

Combatting Cocoa Swollen Shoot Virus Disease: What do we know?
Provedor de dados: 21
Autores: Andres, Christian; Gattinger, Andreas; Dzahini-Obiatey, Henry K.; Blaser, Wilma J.; Offei, Samuel K.; Six, Johan.
Cocoa Swollen Shoot Virus Disease (CSSVD) is one of the major factors limiting cocoa (Theobroma cacao L.) productivity in West Africa. The only cure for CSSVD is to cut out visibly infected trees and the official eradication campaign in Ghana has cut out more than 200 million trees since 1946. 80 years of research on preventive control measures have mainly focused on resistance breeding, mild strain cross-protection (inoculation of cocoa seedlings with a mild strain of the virus to protect against the severe strain) and control of mealybug vectors. Meanwhile, diversification measures such as agroforestry (for shading) or barrier (strip) cropping have received less attention. Despite promising results, CSSVD is more prevalent in the field than ever before....

Over 72 days, 33 lambs were fed: concentrates in stall (S), grass at pasture for 8 hours (8 h), or grass at pasture for 4 hours in the afternoon (4 h-PM). The 4 h-PM treatment did not affect the carcass yield compared to the 8 h treatment. Meat colour development after blooming was unaffected by the treatments. The 4 h-PM treatment increased the proportion of polyunsaturated fatty acids (PUFA; Pb0.0005) and of the highly peroxidizable fatty acids (HP-PUFA; Pb0.001) in meat compared to the 8 h treatment. The S treatment increased lipid oxidation (higher TBARS values) and impaired colour stability (higher H* values) of meat over storage compared to the 8 h and 4 h-PM treatments (Pb0.0005 and P=0.003, respectively). No difference in meat oxidative stability...

Autores: Oehl, F.; Oberson, A.; Tagmann, H.U.; Besson, J.M.; Dubois, D.; Mäder, P.; Roth, H.-R.; Frossard, E.
The aim of this work was to assess to which extent organic farming practices would affect the accumulation of total and available phosphorus (P) in a cropped soil in comparison to conventional practices. In order to achieve this, soil samples were taken from a long-term field trial comparing a non-fertilised control (NON), two conventionally cultivated treatments (MIN, CON), and two organically cultivated treatments (ORG, DYN). Soil samples were taken from each treatment at two depths (0-20 and 30-50 cm) before starting the field trial (1977) and at the end of every three crop rotations (1984, 1991 and 1998). They were then analysed for total P (Pt ), total inorganic P (Pi ), total organic P (Po) and isotopically exchangeable Pi . After 21 years, the...

The objective of this work was to analyze the growth of champa fruit (Campomanesia lineatifolia) as a function of growing-degree days (GDD) in the municipality of Miraflores, in Boyacá, Colombia. Thirty trees were selected at random, and 100 flowers in full bloom were marked in each tree. From the 26th day after flowering until harvest, 10 samples were taken every 15 days to determine the fruit parameters and growth rate. Temperature was recorded to calculate the GDD. From flowering until harvest, 1,489.1 GDD were accumulated over 145 days. Dry and fresh matter mass of pulp, seed, and total fruit were fitted to a logistic growth model, and three growth stages (S1, S2 and S3) were defined. In the S1, growth was slow, and the relative growth remained nearly...

Biodiversity enhancement and utilization - Pest control in brassicas
Provedor de dados: 21
Autores: Luka, Henryk; Barloggio, Guendalina.
In cabbage fields parasitoid wasps (Hymenoptera) use the eggs or larvae of pest butterflies and moths for their own reproduction, ultimately killing them, playing an important role in the biological plant protection strategy. An efficient way to promote this parasitoids in the crop field is to provide them with flower strips as well as companion plants, e.g. cornflower (Centaurea cyanus), that will provide them with food (nectar) and shelter. Between 2007 and 2010 we conducted experiments to test the olfactory attractiveness of different flowers as well as the influence of their nectar on the regulation of the cabbage moth (Mamestra brassicae) as well as on the lifespan and parasitation performance of its antagonists (egg and larval parasitoids).

The aim of the experiment was to investigate the effect of grass mulch and the term of its application on the yield and quality of potatoes and weed biomass under organic system. The experiment with 2 varieties of early potatoes (Finka and Katka), 2 row spacings (28 000 and 38 000 tubers per hectare) and 2 terms of grass mulch application (after planting and after second hoeing) was carried out in the Czech Republic in 2008. Results showed that the yield was influenced mostly by mulching (55.9 %), then by variety (39.2 %) and by growth structure (4.9 %). The highest yield was reached in the variant with grass mulch applicated after planting. The yield of this variant increased statistically about 9.3 t/ha in comparison with control variant (bare soil)....

Autores: Olesen, Jørgen E.; Rasmussen, Ilse Ankær; Askegaard, Margrethe; Kristensen, K.
The possibilities for increasing total grain yield in organic cereal production through manipulation of crop rotation design were investigated in a field experiment on different soil types in Denmark from 1997 to 2000. Three experimental factors were included in the experiment in a factorial design: 1) proportion of grass-clover and pulses in the rotation, 2) catch crop (with and without), and 3) manure (with and without). Three four-course rotations were compared. Two of the rotations had one year of grass-clover as a green manure crop, either followed by spring wheat or by winter wheat. The grass-clover was replaced by winter cereals in the third rotation. Animal manure was applied as slurry in rates corresponding to 40% of the nitrogen (N) demand of the...

Este texto tem por objetivo problematizar a noção de mundo rural e analisar as condições de emergência de novos atores. A partir da ideia de colonização do rural, os personagens que reagem ao processo de racionalização unilateral da vida social e biológica são definidos como novos atores, na medida em que reconstroem relações com o ambiente social e natural. A ação de novos atores inscreve-se no contexto de um campo de disputa de linguagens ecossociais e de distintas ruralidades, construindo-se uma racionalidade que se contrapõe ao domínio da racionalidade instrumental: a racionalidade ambiental ou ecológica.

Fazit  Auch im Ökologischen Landbau gibt es Forschungsbedarf für Resistenzzüchtung, die Schwerpunkte sind aber teilweise andere als im konventionellen Bereich.   Bei Ährenfusariosen kann der Ökologische Landbau die vielfältigen Bestrebungen der konventionellen Züchter nutzen, in dem er die Resistenz bei der Sortenwahl berücksichtigt. Bereits mittelanfällige Sorten könnten hier einen ausreichenden Schutz bieten.  Bei Mutterkorn ist dringender Handlungsbedarf bei Roggen geboten, da hier mit Kulturmaßnahmen wenig Fortschritte zu erzielen sind. Die genetischen Unterschiede lassen gute Selektionsmöglichkeiten erwarten. Bei Triticale scheint aufgrund der bisherigen Ergebnisse wegen des geringen Befalls keine Züchtung erforderlich zu sein.

Autores: Munkholm, L.J.; Schjønning, P.; Jørgensen, M.H.; Thorup-Kristensen, K.
Plough pans have been shown to severely hamper root development, limit rooting depth and reduce crop yields. We evaluated the effect of plough pan compaction on root and yield response for a winter wheat in a field trial conducted in two neighbouring fields (B3 and B4) on a sandy loam. Plots were mechanically loosened to a depth of 35 cm in 1997 (B3 and B4) and again in 1998 (only B4). Perennial grass/clover was grown with limited traffic intensity in 1998-1999 and 1999-2000 for B3 and B4, respectively. The perennial grass/clover was ploughed under in spring 2000 (B3) and spring 2001 (B4) and oats established. After harvest of oats, winter wheat was established. Recompaction treatments were applied to the mechanically loosened plots in 2000 and 2000+2001...

Residual effect and leaching of N and K in cropping systems with clover and ryegrass catch crops on a coarse sand
Provedor de dados: 21
Autores: Askegaard, Margrethe.
The objective of this investigation was to explore the possibility to use clover catch crops instead of ryegrass in organic crop production on coarse sand. Two field experiments were performed, which included different animal manure regimes and different soil K- and N-levels. The residual effect of the clover catch crop on the yields of a succeeding spring barley test crop was significantly higher than for the ryegrass. When animal manure (70 kg total-N ha-1) was added to the succeeding spring barley in the ryegrass system the difference between the clover and ryegrass catch crops disappeared. Thus clover appeared to have the potential for substituting animal manure. Leaching of nitrate-N and K were estimated by means of porous ceramic suction cups...

Approaches for field assessment of resistance to leaf pathogens in spring barley  varieties
Provedor de dados: 21
Autores: Pinnschmidt, H.O.; Hovmøller, M.S.; Østergård, H.
The resistance of spring barley varieties to powdery mildew, leaf rust, leaf scald and net blotch was characterized by using results from inoculated small-plot nurseries and larger survey plots subject to natural infection. The experiments were conducted in different environments. Both trial types often yielded complementary results with respect to the ranking of varieties suggesting that a recommended variety characterization should include both naturally infected survey-type trials and nursery trials in which the most relevant pathogen isolates and/or isolate mixtures or populations are used for inoculation. Average and median values of the diseased leaf area of a variety were highly correlated with each other and with the genotype main effect determined...

Autores: Ankamah-Yeboah, Isaac; Jacobsen, Jette Bredahl; Olsen, Sø'ren Boye.
The purpose of the study was to examine the potential market impacts of the use of insect-based protein for fish feed as an innovative approach out of the fish-meal trap.   An online questionnaire was used to elicit information on fish consumption choices among 610 German consumers using a Discrete Choice Experiment. Mixed logit and latent class logit models were used to model consumers’ preference heterogeneity.   Results showed, that consumers’ preferences for fish attributes such as filets, freshness, ecolabelling and domestic production are heterogeneous and important in consumption choices. The minor share of the respondents was sensitive, while the remaining was indifferent regarding the use of insect based protein as feed in trout production. For...

Impact of low-input meadows on arthropod diversity at habitat and landscape level
Provedor de dados: 21
Autores: Jeanneret, Ph.; Pfiffner, L:; Pozzi, S.; Walter, Th.
In Switzerland, in order to preserve and enhance arthopod diversity in grassland ecosystems (among others), farmers had to convert at least 7 % of their land to ecological compensation areas – ECA. Major ECA are low input grassland, traditional orchards, hedges and wild flower strips. In this paper the difference in species assemblages of 3 arthropod groups, namely spiders, carabid beetles and butterflies between intensively managed and low input meadows is stressed by means of multivariate statistics. On one hand, the consequences of these differences are analysed at the habitat level to promote good practices for the arthropod diversity in grassland ecosystems. On the other hand, the contribution of each meadow type to the regional diversity is...

Provedor de dados: 21
Autores: Weibel, Franco P.; Chevillat, Véronique S.; Rois, Elena; Tschabold, Jean-Luc; Stadler, Walter.
The aim of our study was to find new thinning methods for organic apple production able to fulfil the standards of Bio Suisse, the main label organisation of the organic food sector in Switzerland.   The 17 trials reported were carried out during flowering period in the years 2003, 2004 and 2005 on the cultivars ‘Pinova’, ‘Gala’, ‘Maigold’, ‘Elstar’, ‘Breaburn’, ‘Golden Delicious’ and ‘Otava’ at different sites. The results confirm the good efficiency of mechanical thinning with the rope thinner and the thinning potential of vinasse, a by product of molasses. Different vinasse products were tested (K-Vinasse, light-vinasse, N Vinasse; NK-Vinasse) and it was observed that those containing less nitrogen had a minor thinning effect. To avoid phytotoxicity on...

Redistribution of sulphur during generative growth of barley with different sulphur and nitrogen status.
Provedor de dados: 21
Autores: Eriksen, J; Nielsen, M; Mortensen, JV; Schjørring, JK.
The effect of S and N application on the distribution and redistribution of S compounds in spring barley (Hordeum vulgare L.) was investigated in pot experiments by determination of changes in the content of total-, sulphate- and thiol-S in leaves, ears and stems during the grain-filling period. Nitrogen and sulphur had a clear interactive effect on the yield of all plant parts with little or no effect of S at low N application rates and similar low effect of N without S application. The sulphate concentration in the different plant parts was markedly affected by the S application rate. This effect was most pronounced in leaves, less in stems and least in ears. In S-replete plants leaf S decreased during grain development by an average of 28%, while in...

Formation of canker lesions on stems and black scurf on tubers in experimentally inoculated potato plants by isolates of AG2-1, AG3 and AG5 of Rhizoctonia solani: a pilot study and literature review
Provedor de dados: 21
Autores: Lehtonen, Mari J.; Wilson, Paula S.; Ahvenniemi, Paavo; Valkonen, Jari P.T.
Development of black scurf on potato tubers (cv. Nicola) was compared in plants inoculated with isolates of Rhizoctonia solani of three anastomosis groups (AG2-1, AG3 and AG5) which occur in potato crops in Finland. All isolates induced stem canker lesions but only isolates of AG3 formed efficiently black scurf on progeny tubers. Among the AG2-1 and AG5 isolates tested, only one AG2-1 isolate formed a few sclerotia on 13.5 % of the progeny tubers in one experiment. The data indicate that isolates of AG3 differ from those of AG2-1 and AG5 in having a higher ability to form sclerotia on tubers. Therefore, while AG2-1 and AG5 isolates have a broader host range, AG3 is more efficient in producing black scurf, which provides this anastomosis group with more...

Growth, competitive strength and herbage quality of herbs in multispecies leys
Provedor de dados: 21
Autores: Søegaard, K.; Eriksen, J.; Askegaard, M.
Herbs are established in many organic grasslands due to  expected beneficially properties of nutritive value and biodiversity. However, knowledge about grassland herbs is limited. Three mixtures were therefore established at different grazing/cutting management and slurry application. The competitiveness of the species varied very much. Plantain (Plantago lanceolata) and lucerne (Medicargo sativa) competed best under cutting, opposite chicory (Cichorium intybus) that competed best under grazing. Caraway (Carum carvi), burnet (Poterium sanguisorba) and lotus (Lotus coniculatus) had a relative low competitiveness. Slurry application did not affect the proportion of non-leguminous herbs. The nutritive value differed very much. Caraway had the highest and...

Organic foods trade – a criterion for ecological culture and challenges Bulgaria faces
Provedor de dados: 21
Autores: Ivanova, Daniela; Vasileva, Elka.
The market of organic foods demonstrates a considerable development in the recent years – from a small niche serving a limited number of customers, today it is a market with increasing consumption. The demand of organic products is the result of consumers’ informed needs for healthy and safe foods and their ecological requirements. This is the most dynamic sector of the foodstuffs market in the world but the share of organic sales compared to the total amount remains around 2%.   The paper examines in comparison the possibilities for development of organic agriculture and the organic foods market in Bulgaria in the period of accession to the European union. Based in the assumption that by buying organic products consumers take into account the need of...

Driftsformen har begrænset effekt på jordens evne til at holde på vandet
Provedor de dados: 21
Autores: Schjønning, P.; Iversen, B.V.; Jacobsen, O.H.
Mængden af organisk stof, som man påvirker med almindelig landbrugsdrift, har ikke nævneværdig indflydelse på jordens vandholdende evne.  Anvendelse af husdyrgødning i stedet for mineralsk gødning kan heller ikke forventes at påvirke jordens ledningsevne for vand i pløjelaget.   I forhold til ekstreme driftsformer med et ensidigt (korn-)sædskifte og uden anvendelse af organisk gødning vil en økologisk driftsform give både et større porevolumen og et mere forgrenet poresystem.   Et højt næringsstofniveau giver – uanset tildelingsmetode – flere store porer og bedre ledningsevne for vand i jordlaget under pløjedybde.

Effects of green manure storage and incorporation methods on nitrogen release and N2O emissions after soil application
Provedor de dados: 21
Autores: Carter, Mette S.; Sørensen, Peter; Petersen, Søren O.; Ma, Xiuzhi; Ambus, Per.
More efficient use of green manure-derived nitrogen (N) may improve crop yields and reduce environmental impacts in stockless organic arable farming. In this 3-month incubation study, we tested a new strategy where green manure leys are harvested and preserved until the following spring either as compost mixed with straw or as silage of harvested ley biomass. Grass-clover compost or silage was soil-incorporated by either simulated ploughing (green manure placed at 15 cm depth) or harrowing (green manure mixed into the upper 5-cm soil horizon) in order to assess treatment effects on net release of plant-available N, nitrous oxide (N2O) fluxes, and soil respiration. Grass-clover silage provided the highest net N release with similar results for the two...

Dry matter yield, chemical composition and estimated extractable protein of legume and grass species during the spring growth
Provedor de dados: 21
Autores: Solati, Z; Jørgensen, U; Eriksen, J; Søegaard, K.
BACKGROUND: Knowledge of the variation of extractable protein amount in legumes and grasses as affected by harvest time is important for identifying optimal combinations to enable a high protein production in a biorefinery. The extractability of protein was estimated using the Cornell Net Carbohydrate and Protein System across six harvests during the spring growth.  RESULTS: The estimated extractable protein [g kg−1 dry matter (DM)] defined as the easily available fractions B1+B2 was significantly higher in white clover and lucerne at all harvests while, if the more cell wall attached fraction B3 can be extracted, white clover had the highest extractable protein amongst all species. Total yield of B1+B2 per ha was higher in white clover and red clover at...

We have examined the effect of Pen, an aqueous extract of the dry mycelium of Penicillium chrysogenum, on plant–pathogen interactions. Pen controlled a broad range of pathogens on several crop plants under greenhouse and ﬁeld conditions. Pen protected grapevine from downy and powdery mildew (caused by Plasmopara viticola and Uncinula necator), tomato from early blight (caused by Phytophthora infestans), onion from downy mildew (Peronospora destructor) and apple trees from apple scab (caused by Venturia inaequalis) to a similar extent as fungicides such as copper and sulphur or well-known inducers such as benzothiadiazole or b-aminobutyric acid. Pen had no major direct fungicidal eﬀect and is thus supposed to protect plants by activating their defense...

Provedor de dados: 21
Autores: Petersson, Anneli; Thomsen, Mette Hedegaard; Hauggaard-Nielsen, Henrik; Thomsen, Anne Belinda.
To meet the increasing need for bioenergy several raw materials have to be considered for the production of e.g. bioethanol and biogas.In this study, three lignocellulosic raw materials were studied, i.e. (1) winter rye straw (Secale cereale L), (2) oilseed rape straw (Brassica napus L.) and (3) faba bean straw (Viciafaba L.). Their composition with regard to cellulose, hemicellulose, lignin, extractives and ash was evaluated, as well as their potential as raw materials for ethanol and biogas production. The materials were pretreated by wet oxidation using parameters previously found to be optimal for pretreatment of corn stover (195 1C, 15 min, 2 g l_1 Na2CO3 and 12 bar oxygen). It was shown that pretreatment was necessary for ethanol production from all...

The rapidly growing demand for organic food requires the availability of analytical tools enabling their authentication. Recently, metabolomic fingerprinting/profiling has been demonstrated as a challenging option for a comprehensive characterisation of small molecules occurring in plants, since their pattern may reflect the impact of various external factors. In a two-year pilot study, concerned with the classification of organic versus conventional crops, ambient mass spectrometry consisting of a direct analysis in real time (DART) ion source and a time-of-flight mass spectrometer (TOFMS) was employed. This novel methodology was tested on 40 tomato and 24 pepper samples grown under specified conditions. To calculate statistical models, the obtained data...

Leaching of soil organic carbon and nitrogen in sandy soils after cultivating grass-clover swards
Provedor de dados: 21
Autores: Vinther, F.P.; Hansen, E.M.; Eriksen, J.
Dissolved organic matter is the basis for many of the biogeochemical processes in the soil. Several studies have focused on the formation and losses of dissolved organic matter in forest systems, whereas a limited number have dealt with this aspect in agricultural soils. The purpose of this study was to estimate the leaching of dissolved organic carbon (DOC) and nitrogen (DON), with focus on the period after cultivating grass-clover swards. Grass-clovers were ploughed in the spring prior to sowing cereals followed by either catch crops or bare soil. The concentrations of DOC and DON decreased with soil depth and ranged at 90 cm soil depth between 7 and 21 mg C L-1, and between 1 and 3 mg N L-1, respectively in a sandy loam soil, and between 16 and 63 mg C...

Root pruning reduces root competition and increases crop growth in a living mulch cropping system
Provedor de dados: 21
Autores: Båth, Birgitta; Kristensen, Hanne L.; Thorup-Kristensen, Kristian.
In two field experiments, growth of white cabbage in pure stands was compared with that of cabbage grown in living mulch systems to reduce pest attacks. The roots of the living mulch were pruned early in the season, with the aim of reducing competition and increasing growth of the white cabbage. Root pruning was shown to increase the above-ground biomass of white cabbage, with two prunings giving higher cabbage yields than one, but there were clear differences between the living mulch species tested (red clover, birdsfoot trefoil, salad burnet, winter rye). Below-ground growth and competition were examined by measuring root distribution in minirhizotrons and uptake of 15N placed at different soil depths. These studies showed that the ability of mulch...

Autores: Sharifi, Shervin; Karimi, Javad; Hosseini, Mojtaba; Rezapanah, Mohammadreza.
Rosaceae longhorned beetle, Osphranteria coerulescens, is an important pest of fruit trees that attacks all fruit trees belonging to the family Rosaceae in cold regions of Iran. The potential efficacy of two species of entomopathogenic nematodes (EPN), Heterorhabditis bacteriophora and Steinernema carpocapsae, against last instar larvae of this pest was tested under Laboratory conditions. In plate assays, the larvae were susceptible to both EPN species but were more susceptible to S. carpocapsae (65.0-97.5% mortality) than H. bacteriophora (42.5-87.8%). Both nematode species were able to penetrate and reproduce within O. coerulescens larvae, but reproduction rate for H. bacteriophora was higher than those of S. carpocapsae; however, the penetration rate...

Autores: Touret, Claire.
Scaling up, the organic farming is more and more faced with competitiveness price trends which lead through pressures and tensions to production systems that neglect the environmental and social issues. Therefore biological farmers are forced to wonder about their economic organization model. What model will make it possible to optimize costs without affecting the best practices in social and environmental fields? To contribute to the discussion, the FNAB leads an action research program, where the producers endorse researchers' role. They developed their research question and the linked issues, and then questioned researchers about the main concepts that would help them. In a next step, they built together a theoretical model allowing them to analyze...

Autores: Häring, D.A.; Scharenberg, A.; Heckendorn, F.; Dohme, F.; Lüscher, A.; Maurer, V.; Suter, D.; Hertzberg, H.
Tanniferous forage plants can have beneficial effects on ruminant productivity and health (improved protein supply, bloat safety and antiparasitic properties). However, condensed tannins can also lower palatability, voluntary feed intake and digestibility. The aim of our interdisciplinary project was to generate basic knowledge on plant management, feed palatability and the antiparasitic properties of tanniferous forage plants for their practical application in agronomy, focusing on their usefulness in controlling gastrointestinal nematodes in organic farming. We found that Onobrychis viciifolia (sainfoin), Lotus corniculatus (birdsfoot trefoil) and Cichorium intybus (chicory) were suitable for cultivation under the given temperate climatic conditions,...

Provedor de dados: 21
Autores: Flaten, Ola; Lien, Gudbrand; Koesling, Matthias; Løes, Anne-Kristin.
This article examines the characteristics of and reasons for Norwegian farmers’ ceasing or planning to cease certified organic production. We gathered cross-sectional survey data in late 2007 from organic farmers deregistering between January 2004 and September 2007 (n = 220), and similar data from a random sample of farmers with certified organic management in 2006 (n = 407). Of the respondents  deregistering by November 2007, 17% had quit farming altogether, 61% now farmed conventionally, and 21% were still farming by organic principles, but without certification. Nearly one in four organic farmers in 2007 indicated that they planned to cease certification within the next 5-10 years. From the two survey samples, we categorised farmers who expect to be...

Organic market-gardening farming systems are extremely diverse, ranging from the extensive to the very intensive, although all follow organic standards. This study aimed to analyze the extent to which the diversity of farming ystems in southeastern France may be explained by the marketing channels adopted by growers. Eighteen organic market gardeners were surveyed. Three types of growers were identified, differentiated by the way they combine farming  and marketing systems: (1) growers selling a diversity of food products through local marketing channels, which allows them to increase plant species biodiversity and enhance natural regulations in accordance with agro-ecology principles; (2) specialized growers selling a limited number of food products...

In perennial grasslands R. obtusifolius (broad-leaved dock) is often surrounded by certain plant species. Thus, it is hypothesized for the current study that Rumex can affect their neighbouring plant species by allelopathic interactions. To test this hypothesis, in a series of laboratory and field experiments aqueous extracts of green R. obtusifolius leaves were sprayed on seeds of 14 herbaceous plant species (graminoids, non-leguminuous forbs and leguminuous forbs) commonly native to perennial grasslands and its effects on seed germination compared with those with tap water spraying. An allelopathic effect was defined as inhibitory influence of Rumex extracts on seed germination relative to tap water. Generally, results of the laboratory experiments...

In many crops, the intensive use of pesticides causes major problems both for the environment and for natural ecosystem services. Apple is Europe's most frequently produced orchard fruit, requiring high pesticide input to combat the most important apple insect pests, Dysaphis plantaginea (Passerini) and Cydia pomonella (L.). Here we sought to control these pests by promoting natural enemies using sown perennial flower strips. We trialled these in the alleyways of organic apple orchards in seven European countries. Visual assessments over two years revealed a higher number of natural enemies on plant parts, and specifically in D. plantaginea colonies on trees, in flower strip plots than on trees in control plots with standard orchard vegetation. Trees in...

Do organic farmers feel happier than conventional ones? An exploratory analysis
Provedor de dados: 21
Autores: Mzoughi , Naoufel.
We examine the relationship between organic farming and subjective well-being or life satisfaction. Applying an ordered probit model to a sample of French farmers located in the Provence-Alpes-Côte d'Azur (PACA) area (Southeast), we find that organic farmers report higher levels of life satisfaction, compared to the conventional ones. Moreover, this positive relationship holds for both recently-converted and earlier-converted farmers. Our findings also show that subjective well-being is positively associated with income, profitability, satisfaction at work, social recognition, and good health.

Fate of 15N- and 14C from labelled plant material: Recovery in perennial ryegrass-clover mixtures and in pore water of the sward
Provedor de dados: 21
Autores: Rasmussen, J.; Gjettermann, B.; Eriksen, J.; Jensen, E.S.; Høgh-Jensen, H.
The below ground C and N dynamics leading to organic and inorganic N leaching from perennial ryegrass-clover mixtures are not well understood. Based on the hypothesis that four different plant materials would degrade differently, a 16 months field experiment was conducted to determine (i) the source strength of labelled plant residues in dissolved inorganic N (DIN) and dissolved organic N (DON) in pore water from the plough layer, and (ii) the plant uptake of organically bound N. Litterbags containing 14C- and 15N-labelled ryegrass or clover roots or leaves were inserted into the sward of a ryegrass-clover mixture in early spring. The fate of the released 14C and 15N was monitored in harvested biomass, roots, soil, and pore water percolating from the...

Treatment of Organic Livestock with Medicinal Plants: A Systematic Review of European Ethnoveterinary Research
Provedor de dados: 21
Autores: Mayer, Maria; Vogl, Christian R.; Amorena, Michele; Hamburger, Matthias; Walkenhorst, Michael.
Background: The EC Regulation for Organic Farming states that organic livestock should be treated preferably with phytotherapeutic products. In spite of the high importance of organic livestock in Europe, primarily ruminants, today almost no phytotherapeutic product is registered for livestock. Also, scientific information regarding veterinary phytotherapy is rare. The aim of this paper is to find approaches to cope with health problems of organic ruminants in Europe on the basis of findings from the European ethnoveterinary medicine (EuEVM). Methods: A systematic review of ethno-biomedicinal papers was conducted with the aid of the Scopus database, and 75 papers, from European countries were analyzed regarding ethnoveterinary information. Results: A total...

Qualitative and quantitative evaluation of glucosinolates in cruciferous plants  during their life cycles
Provedor de dados: 21
Autores: Bellostas, Natalia; Sørensen, Jens Christian; Sørensen, Hilmer.
Glucosinolates produced by Brassica species were investigated in relation to biofumigation, a term used to describe the effects some allelochemicals, including glucosinolate derived products, may have on soil-borne pathogens or other herbivores. Four Brassica species of the U-triangle, namely B. nigra (L.) Koch, B. carinata Braun, B. juncea (L.) Czern. and B. rapa L. were compared with respect to their qualitative and quantitative glucosinolate profiles in roots, stems, leaves and reproductive organs. Plants were monitored at four different development stages and the total glucosinolate content as well as their dry matter production as an indication of their potential biomass under field conditions were determined. Glucosinolate levels of up to 120 ìmol g...

Revealed preference analysis of characteristics models
Provedor de dados: 21
Autores: Blow, Laura; Browning, Martin; Crawford, Ian.
Characteristics models have been found to be useful in many areas of economics. However, their empirical implementation tends to rely heavily on functional form assumptions. In this paper we develop a revealed preference approach to characteristics models. We derive the necessary and su¢ cient empirical conditions under which data on the market behaviour of heterogeneous, price-taking consumers are nonparametrically consistent with the consumer characteristics model. Where these conditions hold, we show how information may be recovered on individual consumer’s marginal valuations of product attributes. In some cases marginal valuations are point identi…ed and in other cases we can only recover bounds.  Where the conditions fail we highlight the role which...

Downy mildew caused by the oomycete Plasmopara viticola is the most devastating pathogen of grapevine. In this study, extracts of the bark of eight important northern forestry species were screened to find extracts showing activity against this pathogen and to identify the active compounds. Extracts from all eight species showed activity against P. viticola, the most promising, dichloromethane extracts of three Larix species, almost completely protecting grapevine from downy mildew under semi-controlled conditions. Five promising lead compounds were isolated: larixol, larixyl acetate, lariciresinol and lariciresinol acetate from Larix species and 7a,15-dihydroxydehydroabietic acid from Pinus sylvestris. These compounds showed 90%e100% efficacy. Larixol and...

Production and processing of organically grown fiber nettle (Urtica dioica L.) and its potential use in the natural textiles industry: A review
Provedor de dados: 21
Autores: Vogl, C. R.; Hartl, A.
In Europe, the perennial stinging nettle was cultivated during the 19th century until the Second World War and has a long history as a fiber plant. Clone varieties dating back to the early 20th century are still maintained at European research institutions. The fiber content of clones ranges from 1.2 to 16% dry matter, and fiber yields range from 0.14 to 1.28 Mg/ha. Varietal purity of fiber nettle can only be achieved by planting cuttings. The harvesting of fiber starts in the second year of growth and the crop may produce well for several years. Several agronomic practices influence fiber quality, but causal relations are not yet well understood. Various parts of the fiber nettle plant can be used as food, fodder and as raw material for different purposes...

Autores: Munkholm, Lars J.; Kay, Bev D.
The effect of water regime on aggregate-tensile strength, rupture energy, and friability index was studied in two experiments on sandy loam soils (Glossic Phaeozem/WRB 1998). In Exp. 1, soil from a long-term, 5-yr crop rotation receiving animal manure (dairy farm and grass, DFG) was compared with a soil (continuous cereal crop, CCC), which had grown almost continuous cereals and not received animal manure. In Exp. 2, soil from compacted plots (PAC) and uncompacted reference plots (REF) was sampled. The soil was air-dried and separated into four aggregate-size classes (i.e., 1–2, 2–4, 4–8, and 8–16 mm). Aggregate-tensile strength and rupture energy were measured on air-dry aggregates and on aggregates adjusted to -10, -30, -100, -350 kPa, and -166 MPa...

The formation of the International Federation of Organic Agriculture Movements (IFOAM) at Versailles, France, in 1972 set organic food and farming on a strong future trajectory. It was an initiative of France’s Nature et Progrès, and driven by its then President, Roland Chevriot. IFOAM was founded with the support of a small cluster of kindred organisations: Rodale Press of the USA; the Soil Association of the UK; the Soil Association of South Africa; and the Swedish Biodynamic Association. None of these five organisations bore the term ‘organic’ in their title, nevertheless, the choice of name acknowledged ‘organic’ as the term to signify their common cause. It secured ‘organic’ as the core narrative element and as the international descriptor of what is...

Effect of nose ringing and stocking rate of pregnant and lactating outdoor sows on exploratory behavior, grass cover and nutrient loss potential
Provedor de dados: 21
Autores: Eriksen, J.; Studnitz, M.; Strudsholm, K.; Kongsted, A.G.; Hermansen, J.E.
Nose ringing of outdoor sows is practiced to reduce grass sward damage for environmental reasons but conflicts with natural behaviour considerations. We investigated effects of ringing pregnant and lactating outdoor sows on foraging and explorative behaviour, grass cover and nutrient deposition. The experiment included both ringed and unringed sows. For unringed sows the paddocks were either used continuously throughout the experiment or divided into two and sows were moved half way through the experimental period leaving the first used paddock for regrowth. Ringing did not prevent the sow’s rooting, but rooting was less pronounced, when sows were ringed. On average, ringing increased grass cover from 14 to 38% and from 64 to 81% in paddocks with pregnant...

Despite the recent interest in organic agriculture, little research has been carried out in this area. Thus, the objective of this study was to compare, in a dystrophic Ultisol, the effects of organic and conventional agricultures on soil organism populations, for the tomato (Lycopersicum esculentum) and corn (Zea mays) crops. In general, it was found that fungus, bacterium and actinomycet populations counted by the number of colonies in the media, were similar for the two cropping systems. CO2 evolution during the cropping season was higher, up to the double for the organic agriculture system as compared to the conventional. The number of earthworms was about ten times higher in the organic system. There was no difference in the decomposition rate of...

Abstract. The emissions of nitrous oxide (N2O) and leaching of nitrate (NO3) have considerable negative impacts on climate and the environment. Although these environmental burdens are on average less per unit area in organic than in non-organic production, they are not smaller per unit of product. If organic farming is to maintain its goal of being an environmentally friendly production system, these emissions should be mitigated. We discuss the impact of possible triggers within organic arable farming practice for the risk of N2O emissions and NO3 leaching under European climatic conditions, and possible strategies to reduce these. Organic arable crop rotations can be characterised as diverse with frequent use of legumes, intercropping and organic...

Organic farming and agroforestry are considered as sustainable alternative agricultural practices for intensive agriculture. In a long-term field trial in Scheyern Germany, we evaluated the effects of 21-year organic farming and 4-year agroforestry (robinia and poplar) on microbial community and microbial residues. Microbial biomass and microbial community were determined by fumigation–extraction method and the analysis of phospholipid fatty acid (PLFA), respectively. Microbial residues were evaluated by the measurement of amino sugars. The results showed that organic farming had significantly positive effect on soil organic carbon (SOC) but that it tended to decrease microbial biomass C (MBC), PLFA functional guilds, muramic acid (MurN), and glucosamine...

Urban Organic Farming in Austria with the concept of Selbsternte ("self -harvest"): An agronomic and socio-economic analysis
Provedor de dados: 21
Autores: Vogl, C. R.; Axmann, P.; Vogl-Lukasser, B.
In Vienna, consultants, organic farmers and green-minded consumers have developed a new concept of urban organic farming, called Selbsternte (`self-harvest'). Organic farmers prepare a plot of arable land (the Selbsternte plot) and sow or plant rows composed of 18-23 plant species. In mid-May the plots are divided into subplots that contain 2-6m of  every sown species and are rented to so-called self-harvesters for a period of about 136 days. In 2002 Selbsternte was being practiced at 15 plots in Vienna or in neighboring cities, represented by 861 subplots, with a total area of 68,740m2, and managed by 12 organic farmers for 861 registered self-harvesters. At the Roter Berg plot, experimental subplots were established to evaluate yields and the value of...

The distance between forests and crops affects the abundance of Drosophila suzukii during fruit ripening, but not during harves
Provedor de dados: 21
Autores: Cahenzli, Fabian; Bühlmann, Irene; Daniel, Claudia; Fahrentrapp, Johannes.
Drosophila suzukii (Matsumura; Diptera: Drosophilidae) is an invasive pest with the ability to reproduce not only in various soft fruit crops, but also in numerous wild hosts. Forests and forest edges harbor many wild hosts, provide suitable microclimatic conditions and are therefore thought to enhance the abundance of D. suzukii. Although the comprehension of pest activity based on specific landscape elements is important to implement efficient management strategies, knowledge of how forests affect the abundance of D. suzukii in nearby crops is very limited. We conducted a monitoring study with liquid baited traps across different crops at different distance from the forests. During fruit ripening, more flies were captured in crops closer to forests...

Grass silage for growing-finishing pigs in addition to straw bedding: Effects on behaviour and gastric health
Provedor de dados: 21
Autores: Holinger, Mirjam; Früh, Barbara; Stoll, Peter; Kreuzer, Michael; Hillmann, Edna.
In organic and other enriched housing systems, straw is commonly used as enrichment material for pigs. Its positive effects on health and behavioural welfare are well known. However, potential additional impacts of roughages (other than straw) have rarely been investigated. On six organic farms, we therefore investigated how providing grass silage affects behaviour, gastric health and performance of growing-finishing pigs. Per farm, two to four pens were included in the experiment, with group sizes ranging from five to 26 pigs (total n = 368), and stocking density ranging from 1.65 to 3.50 m2 per pig during finishing. Groups were provided with either grass silage (SIL) or straw (CON) in a rack. Long-stack straw was used as bedding material in all pens....

Effect of production system, alternative treatments and calf rearing system on udder health in organic dairy cows
Provedor de dados: 21
Autores: Wagenaar, J.-P.; Klocke, P.; Butler, G.; Smolders, G.; Nielsen, J.H.; Canever, A.; Leifert, C.
In the last decade the main goals of organic dairying have been to attain acceptable levels of milk production, increase opportunities for animals to perform species own behaviour, resulting in improved animal welfare and animal health, and minimize the use of therapeutic interventions, including the reduction of the (preventive) use of antibiotics. Maintaining animal health without the use of therapeutic interventions is a major challenge for organic dairy farmers. In particular, udder health remains a major problem in both conventional and organic farming. In the QualityLowInputFood (QLIF) project udder health status and management were assessed in different production systems and European regions. These studies suggest that good udder health can be...

Carbon isotope discrimination and water use efficiency relationships of alfalfa genotypes under irrigated and rain-fed organic farming
Provedor de dados: 21
Autores: Moghaddam, Ali; Raza, Amir; Johann, Vollmann; M.Reza, Ardakani; Wolfgang, Wanek; Gabriela, Gollner; Juergen K., Friedel.
Carbon isotope discrimination (∆) has been proposed as a method for evaluating water use efficiency (WUE) in C3 plants and as a precise technique for screening plants with higher tolerance under water deficit conditions. In this research, 18 alfalfa genotypes from different geographical origins were evaluated under irrigated and rain-fed conditions in organically manged fields in Austria. Significant differences were found amongst harvests for ∆-shoot under both conditions while genotype by harvest interaction was only significant under irrigated condition. Drought stress under rain-fed condition reduced the overall mean of water use efficiency and carbon isotope discrimination responses(up to 34%), but the ratios of reduction differed for characters and...

Autores: Thorup-Kristensen, Kristian.
I artiklen præcenteres resultater og erfaringer fra 8 års forsøg med økologisk grønsagssædskifte ved Danmarks JordbrugsForskning i Årslev. En af de centrale resultater er at det har meget stor effekt at holde markerne grønne i efteråret. Selvom der har ingået mange forskellige typer efterårsdække, fra helårsgrøngødning, til efterafgrøder med og uden bælgplanter og endda kålstub der har fået lov at gro videre efter at kålhovederne er høstet, så har det grundlæggende haft den samme effekt. Med plantedække i efteråret efterlades der langt mindre N i jorden som kan udvaskes, men om foråret mineraliseres der væsentligt mere N i jorden som kan udnyttes af den følgende afgrøde. Grøngødning giver naturligvis større mineralisering end f.eks. kålstub, men den...

Autores: Springer, Bettina.
Der Strukturwandel ist in vollem Gang. In den letzten 15 Jahren sind viele Landwirtschaftsbetriebe in der Schweiz aufgegeben worden – umliegende oder verwandte Betriebe haben «profitiert». Sie sind gewachsen, haben ihre Strukturen gewandelt. Wo vor 15 Jahren inmitten von 17 ha Wiesland ein Anbindestall für 15 Kühe, Jungvieh und Kälber stand, steht heute auf der neu gebauten Güllengrube ein Laufstall für 40 Kühe. Auch Heuraum musste zusätzlich gebaut werden, ein weiterer Traktor angeschafft werden, und ein neuer Doppelschwader war nötig. Natürlich, wie sollten denn die 48 ha bewirtschaftet werden?

Comparison of part-time grazing and indoor silage feeding on milk production
Provedor de dados: 21
Autores: Sairanen, Auvo; Khalili, Hannele; Virkajärvi, Perttu; Hakosalo, Jenni.
Cows were assigned randomly to indoor silage feeding (with 2 h outdoor exercise) or part-time grazing treatment in two different experiments. One group was kept in confinement with ad libitum grass silage within each experiment. The other group had ad libitum grass silage indoors and they were put out on grass pasture during part of the 24 hour period, 12 hours (night, Experiment 1) and 6 hours (day, Experiment 2) in June, July and August. In Experiment 2, the concentrate (9 kg d-1) was given at two crude protein levels: high crude protein [185 g kg-1 dry matter (DM)] and low crude protein (135 g kg-1 DM). In Experiment 1, night-time grazing increased total DM intake and milk (3.9 kg d-1) production. There was interaction between month and forage feeding...

Alternative fungicides to control apple scab in organic apple production:  results of an orchard trial in 2003
Provedor de dados: 21
Autores: Lindhard, Hanne; Paaske, Klaus; Bengtsson, Marianne V.; Hockenhull, John.
Apple scab, caused by the fungus Venturia inaequalis, is the disease that most often decreases yield and causes loss of fruit quality in organic apple production. Damage to the fruits consists of brown to black spots, but in some years and on some varieties attacks can result in small misshapen fruits, that are totally unsuitable for fresh consumption.

Autores: Garmo, Randi T.; Martin, A.D.; Thuen, E.; Havrevoll, Ø.; Steinshamn, H.; Prestløkken, E.; Randby, Å.; Eknæs, M.; Waldmann, A.; Reksen, O.
Progesterone profiles in Norwegian Red cows were categorized, and associations between the occurrence of irregularities in the profiles and the commencement of luteal activity were investigated. The cows were managed in 3 feeding trials from 1994 to 2001 and from 2005 to 2008 at the Norwegian University of Life Sciences. The cows were followed from calving, and the milk samples collected represented 502 lactations from 302 cows. Milk samples for progesterone analysis were taken 3 times weekly from 1994 throughout 1998 and from 2005 to 2008 and 2 times weekly from 1999 to 2001. Commencement of luteal activity was defined as the first day of 2 consecutive measurements of progesterone concentration ≥3 ng/mL not earlier than 10 d  after calving. Delayed...

A comparative study of nitrate leaching from intensively managed monoculture grass and grass-clover pastures
Provedor de dados: 21
Autores: P.S., Hooda; M., Moynagh; I.F., Svoboda; H.A., Anderson.
Nitrate leaching losses from intensively managed monoculture grass and grass-clover pastures were measured during 1994-96 at a long-term experimental farm in south-west Scotland. Field-size lysimeter plots were established in 1993 on the existing pastures on a silty clay loam non-calcareous gley. No fertilizer-N was applied to the grass-clover, while the monoculture grass was fertilized with c.240 kg N ha-1 year-1, but both swards received 2-3 cattle slurry applications annually (120-390 kg total N ha-1 year-1). The pastures supported 2-3 cuts for silage conservation, and were grazed by dairy cattle and stocked with sheep during the winter months.   Initially, leachate nitrate concentrations from the fertilized grass were considerably larger than those...

Motives for buying local, organic food through English Box Schemes
Provedor de dados: 21
Autores: Hashem, Shadi; Migliore, Giuseppina; Schifani, Giorgio; Schimmenti, Emmanuele; Padel, Susanne.
The aim is to explain the growing interest of English consumers in local organic food sold through box schemes, by providing insights into the motives of customers of such schemes and examining the relationship with their awareness about problems of the agro-food system.  A mixed methods approach combined in-depth interviews with 22 box scheme customers with a quantitative survey of 416 consumers, analysed by means of Principal Component Analysis (PCA) and an Ordered Logit model.  Consumers of small local organic box schemes in England are both altruistically and hedonistically motivated. This includes a strong political motivation to change the current food system, as shown by the strong influence of an anti-globalisation factor and wanting to support...

Follow-up of stable isotope analysis of organic  versus conventional milk
Provedor de dados: 21
Autores: Molkentin, Joachim; Giesemann, Anette.
Analysis of the stable isotope ratio of carbon (δ13C) and α-linolenic acid (C18:3ω3) content in milk fat is a useful indicator of organic milk production. Referring to corresponding measurements, further analyses of stable isotope ratios were performed in 120 samples of conventionally and organically produced whole milk collected from German retailers during a period of 18 months.  Conventional milk predominantly exhibited higher δ15N values than organic milk, the latter of which never exceeded a maximum δ15N threshold value of 5.50‰. Measurements of δ34S did not differ significantly between organic and conventional milk. Because δ13C, in general, is related to maize consumption, δ13C in milk protein and δ13C in milk fat were equally suited for...

A flexible tool for simulation of soil carbon turnover
Provedor de dados: 21
Autores: Petersen, B.M.; Olesen, J.E.; Heidmann, T.
Existing models of soil organic matter (SOM) turnover are implemented within rigid and often complex modelling environments, which makes the testing of influence of SOM model structure a rather difficult task.  A new soil carbon turnover simulation tool is presented (C-TOOL v. 1.0). It facilitates the construction of a wide range of user-definable SOM models based on linked SOM pools and a decay described for each pool by first order kinetics. Simulation of carbon isotopes 13C and 14C is facilitated. No programming is necessary for defining or redefining models, as the model structure is given in set-up files. The program is fast, and can utilise a range of time-steps, which enhances the computation of steady level SOM contents.  The ability of C-TOOL to...

Design of an organic farming crop rotation experiment
Provedor de dados: 21
Autores: Olesen, Jørgen E.; Askegaard, Margrethe; Rasmussen, Ilse Ankær.
A field experiment is conducted which focuses on crop rotations for cereal production in organic farming. The objective of the experiment is to explore the possibilities for both short-term and long-term increases in organic cereal production through manipulation of crop rotation design on different soil types. This paper describes the design of a rather complex experiment, and later papers will describe and discuss the results. Three factors are included in the experiment in a factorial design with two replicates: A) fraction of grass-clover and pulses in the rotation (crop rotation), B) catch crop (with or without catch crop or bi-cropped clover), and C) manure (with or without animal manure applied as slurry). All fields in all rotations are represented...

Overview of supply and demand for concentrated organic feed in the EU in 2002 and 2003. Summary of draft project report of EEC 2092/91 (Organic) Revision
Provedor de dados: 21
Autores: Padel, Susanne.
Annex IB of the EU Regulation on organic farming (2092/91) sets out that animals on organic farms should be fed with feed stuffs from organic farming systems. Only if organic feed is not available in sufficient quantity and quality, can a set percentage of those non-organic components be used that are listed in Annex II. The derogations for using conventional feed are due to expire in August 2005 and currently negotiations in Brussels are concerned with what rules will apply after August. Several Organisation of  the organic sector have already taken significant steps to reduce the reliance on conventional feed for ruminants. In Denmark, all organic cattle have to be fed 100% organic diets, and BIOLAND and DEMETER in Germany have also included this in...

Co-production of ethanol, biogas, protein fodder and  natural fertilizer in organic farming – evaluation of a concept for a farm-scale biorefinery
Provedor de dados: 21
Autores: Oleskowicz-Popiel, Piotr; Kádár, Zsófia; Heiske, Stefan; Klein-Marcuschamer , D.; Schmidt, Jens Ejbye.
The organic farming community has long been recognized for its environmental awareness and has been seeking ways to reduce greenhouse gas emissions and become energy independent. In that regard, ethanol can substitute a fraction of the gasoline used by farming equipment, whereas biogas can fuel the production of heat and electricity for the farm. We investigated the addition of a biorefinery to an organic farm, where ethanol was produced from germinated rye grains and whey and the effluent was separated into two streams: the protein-rich solid fraction, to be used as animal feed, and the liquid fraction, which can be co-digested with clover grass silage to produce biogas. The effluent from the anaerobic digestion process was assumed to serve as natural...

Co-operative or coyote? Producers’ choice between intermediary purchasers and Fairtrade and organic co-operatives in Chiapas
Provedor de dados: 21
Autores: Milford, Anna Birgitte.
Coffee producers in many parts of the world have the option of either becoming a member of and selling their coffee to a Fairtrade and organic co-operative, or selling it to a ‘‘coyote’’, the Central American nickname for intermediary purchaser. This study investigates why different producers make different choices, looking at both material and immaterial costs and benefits of the two choices. A qualitative study from Chiapas (Mexico) finds that a main reason for not choosing the co-operatives is the production requirements that follow organic certification. A survey on production costs confirms that members of an organic co-operative have more work hours than nonmembers in the same area. A probit analysis indicates that both coffee plot size and number of...

Robustness in the mineral supply from temporary grasslands
Provedor de dados: 21
Autores: Høgh-Jensen, Henning; Søegaard, K.
The current study examined the capacity of different temporary grassland legume-grass mixtures under different N supply levels to supply similar amounts of elements in systems where the herbage is cut and feed. Mixtures showed a good robustness in supplying equal amounts of mineral elements in the combined herbage as well as equal concentrations in dry matter of mineral elements compared to the same species in monocultures. The reasons for the mixed systems to be able to buffer differences in N supply levels as well as different compositions of the mixtures were that legume leaves and stems had similar concentrations of mineral elements, whether in monocultures or in mixtures with grasses. Grasses in mixture with legumes had however higher N, Ca, S, Zn, Cu...

Autores: Mogensen, Lisbeth; Troels, Kristensen.
A total of 246 Danish Holstein cows were included in three experiments. In each experiment, Barley (B) was compared with another type of supplementary feeds: a Concentrate mixture (C), Grass pellets (G), or Fodder beets (F). The concentrate mixture resulted in a higher (P = 0.002) milk yield (25.9 vs 23.7 kg), a tendency of a lower (P = 0.07) fat content (4.08 vs 4.25%), and a higher (P = 0.006) ECM yield (25.7 vs 24.1 kg) compared to feeding barley as supplement at the same energy level. Grass pellets resulted in a lower (P = 0.01) milk fat content (3.74 vs 4.07%), a tendency of a lower (P = 0.12) protein content (3.14 vs 3.23%), but no different milk or ECM yield compared to feeding barley as supplement at the same dry matter level.

Autores: Halpin, Darren; Daugbjerg, Carsten.
While group scholars have long noted instances of change in overall form – say from amateur scientific group to environmental campaign group – the literature is short on persuasive accounts of the mechanism(s) that drive or constrain such radical change. How can we explain groups getting from form A to form B? In this article we explore how tools from the historical institutionalism literature might aid in the analytical process. Specifically we focus on the combination of focussing events, internal challengers to the status-quo, and the capability of challengers to demonstrate to key audiences that the ‘radical’ change is in some way consistent with the founding ideology of the group. We demonstrate the application of this approach by examining a case of...

Effects of feeding finisher pigs with chicory or lupine feed for one or two weeks prior to slaughter with respect to levels of Bifidobacteria and Campylobacter
Provedor de dados: 21
Autores: Jensen , Annette Nygaard; Mølbak, Lars; Hansen, Laurits Lydehøj; Baggesen, Dorte Lau.
Prebiotics are non-digestible oligosaccharides acting by stimulating the growth of bacteria being beneficial for the gastrointestinal health of the host and may serve as a means to prevent pathogens. This study aimed to assess if inclusion of chicory or lupines (prebiotics) in the diet of pre-slaughter pigs for just 1 or 2 weeks could change the composition of their intestinal microbiota, stimulate the growth of bifidobacteria and help to lower the level of the important foodborne pathogen Campylobacter spp.  A total of 48 pigs of initial 90 kg live weight were fed with either a lupine (organic concentrate with 25% blue lupine seed), chicory (organic concentrate with 10% dried chicory roots) or control (100% organic concentrate) diet for 1 week (24 pigs)...

Quantifying biological nitrogen fixation of different catch crops, and residual effects of roots and tops on nitrogen uptake in barley using in-situ 15N labelling
Provedor de dados: 21
Autores: Li, Xiaoxi; Sørensen, Peter; Li, Fucui; Petersen, Søren O.; Olesen, Jørgen E.
Background and aims  Contributions of legume-based catch crops (LBCCs) to succeeding cereals may be significant. We quantified biological N fixation (BNF) and residual N effects of contrasting CC tops and roots.    Methods  BNF of three LBCCs (red clover, winter vetch, perennial ryegrass-red clover mixture) was quantified in microplots by 15N labelling. Their residual effects on spring barley were tested against two non-LBCCs (perennial ryegrass, fodder radish) after spring incorporation of CC tops or roots in monoliths.    Results  Total N accumulated in LBCCs was 153–226 kg N ha−1, of which 62–66 % was derived from BNF in tops and 31–46 % in macro-roots (0–18 cm soil). Macro-roots represented 31–50 % of total plant N. LBCCs showed similar capacity for...

Provedor de dados: 21
Autores: Laursen, Kristian Holst; Hansen, Thomas Hesselhøj; Persson, Daniel Pergament; Schjørring, Jan Kofod; Husted, Søren.
The multi-elemental capacity of Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) is rarely fully utilized in traditional full-quantitative analysis. The main obstacles are limited availability of multi-elemental standards and the need for time-consuming external calibrations. In this study, a novel semi-quantitative quadrupole ICP-MS based method for multi-elemental fingerprinting of plant tissue was developed as a high-throughput alternative to full-quantitative analysis. The main analytical objectives were low data acquisition time (&lt;60 seconds), detailed coverage of the atomic mass range from 7Li to 238U and discrimination power similar to full-quantitative analysis based on chemometric data analysis. The method was tested on grains of different...

The special quality of foods from alpine grazing systems concerning their fatty acid (FA)composition is well established. However, the contribution of different specific vegetationtypes and the animal’s genotype to this alpine effect is still unclear. In the present study,the FA profiles of muscle and adipose tissue lipids were determined in lambs that hadgrazed either an intensively managed lowland pasture or one of three characteristic alpinevegetation types differing in plant species number and composition, forage quality andamount, and composition of phenolic compounds and FA. On each vegetation type and intwo subsequent years, two groups of lambs (seven Engadine sheep, ES; and seven ValaisianBlack Nose sheep, VS) grazed for 9 weeks and were...

Cirsium arvense responses to stubble cultivation and   catch crops in organic cropping systems
Provedor de dados: 21
Autores: Holst, Niels; Melander, Bo; Rasmussen, Ilse A.; Hansen, Preben Klarskov.
Field studies on perennial weeds, such as Cirsium arvense, are necessary to study the systemic effects of weed control. In this study we analyse the responses in above-ground C. arvense biomass and crop yield from results obtained in two organic field experiments, both combining stubble cultivation with post-harvest catch crops. A range of catch crops was investigated, varying in both species mixture and method of establishment, yet stubble cultivation was the only treatment found to reduce C. arvense density. The effect was even seen only in one year when a harsh winter acted synergistically with soil tillage. C. arvense exhibited density-dependent growth, in terms of above-ground biomass at harvest, with an estimated max. exponential growth rate of...

Organic food labels as a signal of sensory quality-insights from a cross-cultural consumer survey
Provedor de dados: 21
Autores: Hemmerling, Sarah; Obermowe, Tim; Canavari, Maurizio; Sidali, Katia Laura; Stolz, Hanna; Spiller, Achim.
Organic food labels are promising tools to transmit the positive image of organic products to consumers. Besides health-related aspects and environmental concerns, declaration of organic quality may have a positive impact on consumers’ taste perception. Many studies have proven the positive image of organic products, but very few have considered the link between labeling a product as organic and the consumer’s evaluation of sensory quality. This paper therefore investigates how organic consumers from six European countries (Germany, France, Italy, Poland, Switzerland, and the Netherlands) are influenced by the information that strawberry yogurt is produced organically or conventionally. Within the framework of a European Union-funded research project, a...

Pioneers of organic farming often faced social challenges as their innovative ideas on agriculture not only encountered opposition in the conventional farming community, but led to stigmatization of organic farmers as social deviants. In this study, we examine what kind of stigma management strategies pioneer organic farmers engage with in order to cultivate an alternative positive image of themselves. Our research is based on the interviews with 14 pioneer organic farmers. Based on a qualitative analysis of interviews, we provide a model of those strategies that the creation of from a stigmatized to valued identity requires.

The advantages of low input livestock production on large or unfenced pastures, including high animal welfare, positive impacts on biodiversity and low production costs may be challenged by losses due to undetected disease, accidents and predation. Precision livestock farming (PLF) systems enable remote monitoring on an individual level with the potential for predictive warning. Monitoring body temperature (Tb) and heart rate (HR) could allow for development of early warning systems for not only sickness and behavior, but also oestrus or parturition. In this study, we tested physiological sensors in free grazing Norwegian white sheep in Norway. Forty Tb sensors and thirty HR sensors were surgically implanted in 40 lambs and 10 ewes; 20 lambs in one herd...

O vime contribui para a manutenção de mais de 1.400 unidades produtivas familiares no Planalto Sul Catarinense. A espécie tradicionalmente utilizada é o Salix x rubens, que apresenta boa aceitação entre os produtores. Esses, porém, reclamam do declínio das lavouras e da elevada taxa de ramificação do vime produzido. O presente trabalho avaliou as condições de implantação e a produtividade dos vimais dessa região. A aplicação do método adaptado de Summer &amp; Farina (1986) aos dados coletados permitiu o estabelecimento de regiões de insuficiência, balanço e excesso para as principais características de implantação das lavouras. O adensamento e a redução do tamanho da estaca no plantio, que vem ocorrendo na região, estão reduzindo a longevidade dos vimais.

The objective of this article is to determine the economic performance of organic farms compared with conventional farms. The analysis included a set of farms the concentration of which is in natural and climatic conditions typical for this type of farming high. The outputs may be therefore considered representative and generalised.  In order to determine the performance of these farms, their production basis was first assessed by using the indicators of available assets and assets coverage resources. Consequently, their efficiency was assessed based on the profit. For the purposes of comparison, the profit was (in various forms) converted to a hectare of agricultural land. The economic results were also compared with the average level achieved in the EU....

Provedor de dados: 21
Autores: Mohammadreza, Davari; Shriniwas, Sharma; Mohammad, Mirzakhani.
The present investigation was undertaken to assess the residual influence of organic materials and biofertilizers applied to rice and wheat on yield, nutrient status, and economics of succeeding mung bean in an organic cropping system. The field experiments were carried out on the research farm of IARI, New Delhi during crop cycles of 2006 to 2007 and 2007 to 2008 to study the effects of residual organic manures, crop residues, and biofertilizers applied to rice and wheat on the performance of succeeding mung bean. The experiment was laid out in a randomized block design with three replications. Treatments consisted of six combinations of different residual organic materials, and biofertilizers included residual farmyard manure (FYM) and vermicompost (VC)...

CN-SIM - a model for the turnover of soil organic matter. I: Long term carbon development
Provedor de dados: 21
Autores: Petersen, B.M.; Berntsen, J.; Hansen, S.; Jensen, L.S.
A computer model is presented that describes the flow of C and N in the soil. It employs a structure with conceptual compartments. Organic matter is represented by seven different compartments, two for added matter, two for soil microbial biomass, one for microbial residues, one for native organic matter, and one for inert organic matter. The latter pool probably represents both truly inert matter, and matter with a very slow turnover. This paper describes the parameterisation and performance of this model on selected long-term field data from United Kingdom, Sweden and Denmark. Statistical methods were employed to optimise parameters, and obtain proximate confidence intervals for these parameters. Very satisfactory simulations could be acquired, using the...

Provedor de dados: 21
Autores: Madsen, Helena; Talgre, Liina; Eremeev, Viacheslav; Alaru, Maarika; Kauer, Karin; Luik, Anne.
The effects of different winter cover crops and their combination with composted cattle manure on weeds and crop yields were investigated within a five-field crop rotation (barley undersown with red clover, red clover, winter wheat, pea, potato) in three organic cropping systems. The control system (Org 0) followed the rotation. In organic systems Org I and Org II the winter cover crops were used as follows: ryegrass (Lolium perenne L. in 2011/2012) and a mixture of winter oilseed-rape (Brassica napus ssp. oleifera var. biennis) and winter rye (Secale cereale L.) in 2012/2013 before pea; winter oilseed rape before potato and winter rye before barley. In Org II system composted cattle manure was also applied. In comparison with the control system, the...

New Challenges in Underprivileged Regions Call for People-Centered Research for Development
Provedor de dados: 21
Autores: Høgh-Jensen, H.; Oelofse, M.; Egelyng, H.
The need for enhancing food production and availability in underprivileged regions of the world requires the attention of scientists. This article explores the possibilities for rethinking agricultural research for development (R4D) in the light of new challenges characterized by a high degree of scientific uncertainty along with associated intense political differences of interest. New challenges that particularly influence food production in underprivileged regions include global climate change, globalization of food chains, and emerging low-carbon energy systems. We argue that by applying the people-centered sustainable livelihoods approach as a research paradigm in R4D, researchers may be more successful in producing knowledge that is useful to...

Provedor de dados: 21
Autores: Lund, Ivar; Dalsgaard, Johanne; Hansen, Jonea Høeg; Jacobsen, Charlotte; Holm, Jørgen; Jokumsen, Alfred.
The study compared the effect of four either fresh or force oxidized organic plant oils in diets for juvenile rainbow trout (Oncorhynchus mykiss) in which 47% of conventional LT fish meal protein was substituted by a mixture of 3 organic plant protein concentrates. Fish oil was completely substituted with either organic linseed oil; rape seed oil; sunflower oil or grape seed oil and evaluated based on feed intake, feed utilization, growth and digestibility. None of the plant oils affected feed intake and growth parameters. Organic plant oils had all a positive effect on lipid digestibility as compared with the fish oil based control diet, despite the very different FA profiles. The organic vegetable oils did not undergo autoxidation, as opposed to the fish...

Four New Strategies to Grow the Organic Agriculture Sector
Provedor de dados: 21
Autores: Paull, John.
This paper presents four new strategies for growing the organic agriculture sector. Globally there are 51 million hectares of certified organic agriculture land and a further 39 million hectares of wild culture land. For the past two decades organic agriculture has been growing at 11.9% per annum, thereby doubling the size of the sector every six years. Nevertheless, despite ten decades of advocacy for organics, only 1.1% of the world’s agricultural land is certified organic. From the outset, the strategy has been to advance the sector ‘one farm at a time’. This strategy has left the organics sector well short of the vision of the pioneers of organics who saw organic farming as a universal solution and a practice suited for all farmers and all agriculture....

A Agroecologia como um campo científico.
Provedor de dados: 21
Autores: Borsatto, Ricardo Serra; Carmo, Maristela Simões do.
Este texto teórico aborda os desafios de a Agroecologia se consolidar como um campo científico, visto que muitos pesquisadores envolvidos em sua temática requerem para ela o status de Ciência, ao mesmo tempo em que a sua postura epistemológica questiona severamente os paradigmas vigentes no campo científico. Aqui se defende que a Agroecologia pertence também ao campo científico, não negando que ela possa pertencer a outros campos, e que esse pertencimento é estratégico para evitar o seu desvirtuamento. A partir disso remete ao funcionamento dos campos científicos na busca de elementos que auxiliem a Agroecologia a superar as críticas, marginalizações e preconceitos de uma nova ciência que deseja estabelecer os seus novos paradigmas.

In vitro pepsin digestibility and amino acid composition in soluble and residual fractions of hydrolyzed chicken feathers
Provedor de dados: 21
Autores: Adler, Steffen A.; Slizyte, Rasa; Honkapää, Kaisu; Løes, Anne-Kristin.
Beta-keratin in poultry feathers is a structural protein that is resistant to degradation due to disulfide and hydrogen bonds. Feather meal can be a valuable feed compound if the digestibility can be increased. The objective of the present study was to analyze the effects of chemical, enzymatic, and pressure-thermic treatments for chicken feathers on solubility, in vitro protein digestibility (IVPD), and amino acid composition of solubilized and residual fractions. Two experiments were conducted. In experiment 1, models for solubility and IVPD were developed including the above factors applying a central composite face-centered design. Addition of sodium hydroxide (NaOH) and sodium sulfite (Na2SO3), and autoclaving time affected solubility and IVPD of the...

Impact of drying techniques, seasonal variation and organic growing on flavor compounds profiles in two Italian tomato varieties
Provedor de dados: 21
Autores: Paolo, D; Bianchi, G; Morelli, C; Speranza, G; Campanelli, G.; Kidmose, Ulla; Lo Scalzo, R.
The industrial transformation of tomato (Lycopersicon esculentum Mill.) produces processed foods, such as dried  tomatoes. In this study two varieties (SaAb and PerBruzzo), grown in three cropping systems (one conventional and two organic ones), were processed by two types of small-scale drying (oven or sun drying), over two years of production. The dried samples were analyzed for their non-volatile and volatile composition, relating the results with sensory analysis. The multivariate analysis performed on collected data allowed a detailed comparison of the effects of processing, year-to year variation and cropping systems. Results indicated that drying methods mainly influenced the composition and flavor profile, also affected by the production year. The...

Soil treatments and rootstocks for organic apple production
Provedor de dados: 21
Autores: Lindhard Pedersen, Hanne; Pedersen, Birgitte.
The apple variety 'Retina' is recommended for organic production in Denmark. Yet, there is no knowledge regarding the optimal rootstock for this variety. Better knowledge is also needed on production techniques, such as weed control, where different machinery for mechanical weeding is available.     Therefore, we tested the combined effect of different rootstocks and weeding techniques including soil covering with straw. As organic growers discus the necessity of weed cleaning at all, the natural vegetation was used as control treatment in the trials.

Farm size and landscape composition in relation to landscape changes in Denmark
Provedor de dados: 21
Autores: Levin, Gregor.
This paper explores relationships between farm size and landscape composition in terms of densities of uncultivated landscape elements and sizes of agricultural fields. The study is based on national agricultural registers for Denmark and on aerial photo interpretation of three study areas, representing different Danish landscape types.  Results indicate significantly smaller fields and significantly higher densities of unculti-vated landscape elements on small farms (&lt;25ha). At national level, current differences between small and large farms are to some extent caused by landscape changes between 1998 and 2004. Analyses of the study areas indicate that current differences between small and large farms mainly evolved between 1982 and 2002, while the...

Autores: Bjørnskov, C.; Svendsen, G.T.
How to construct a robust measure of social capital? This paper offers two contributions. The first is an attempt to establish a broad social capital measure based on four indicators, the Freedom House Index, an index of perceived corruption from Transparency International, and scores on civic participation and generalized trust. This measure is then applied by comparing the level of social capital in 25 countries from Western and Eastern Europe. Our nine-cluster analysis shows that Switzerland has the highest score, followed by the Netherlands and Scandinavia. At the other end of the continuum we find post-communist countries and southern Italy. The findings for this specific sample suggest that institutions matter for social capital and the relationship...

Inadequate rodent control is considered to play a role in Toxoplasma gondii infection of pigs. This issue was addressed in the current study by combining a 4-month rodent control campaign and a 7-month longitudinal analysis of T. gondii seroprevalence in slaughter pigs. Three organic pig farms with known rodent infestation were included in the study. On these farms, presence of T. gondii in trapped rodents was evaluated by real-time PCR. All rodent species and shrews investigated had T. gondii DNA in brain or heart tissue.

Säen, Stecken oder Pflanzen: Welches Verfahren eignet sich für Biozwiebeln am besten?    Semer, planter ou repiquer: Quel est le meilleur procédé pour les oignons bio?
Provedor de dados: 21
Autores: Vieweger, Anja; Koller, Martin; Lichtenhahn, Martin.
Biozwiebeln werden vor allem als Steckzwiebeln angebaut. Das schnelle Wachstum am Anfang und die gegenüber Säzwiebeln verkürzte Kulturzeit erleichtern die Unkrautbekämpfung wesentlich. Der Anbau über Steckzwiebeln hat allerdings auch Nachteile: Nur wenige Zwiebelsorten sind für diesen Anbau geeignet und diese haben eine eher schlechte Lagerfähigkeit, weil sie weniger schalenfest als übliche Säzwiebelsorten sind. Auf Steckzwiebeln können zudem Krankheiten übertragen werden. Alternativ verwenden einige Biobetriebe Zwiebel-Jungpflanzen, um der Kultur einen Vorsprung gegenüber dem Unkraut zu geben.   Auf dem Betrieb von Samuel Lüscher in Holziken AG (Schweiz) wurden die drei Kulturverfahren in einem Versuch einander gegenübergestellt, wobei das Hauptinteresse...

Ozonated water and chlorine effects on the antioxidant properties of organic and conventional broccoli during postharvest.
Provedor de dados: 21
Autores: LIMA, Giuseppina Pace Pereira; MACHADO, Tatiana Marquini; OLIVEIRA, Luciana Manoel de; BORGES, Luciana da Silva; PEDROSA, Valber de Albuquerque; VANZANI, Paola; VIANELLO, Fabio.
There is growing interest in studies on sanitizers other than chlorine that can maintain the quality of organic products without affecting their phytochemical content. The effects of using chlorinated and ozonized water treatments, as sanitizing procedures, on the post-harvest quality of organic and conventional broccoli (Brassica oleracea L.) cv. Italica was evaluated. The biochemical parameters (chlorophyll, polyphenols, flavonoids, vitamin C and antioxidant capacity) of the broccoli samples were analyzed at day 0 (arrival of the plant from the field, original features), and 1, 4 and 7 days after harvest. The polyamine analysis was performed on arrival of the plant from the field and on the first and seventh days. The cultivation procedure influenced...

Reduction of viability of soil borne inoculum of common bunt (Tilletia tritici) by collembolans
Provedor de dados: 21
Autores: Dromph, Karsten; Borgen, Anders.
Teliospores of Tilletia tritici  (syn. T.caries) were fed to five species of collembolans: Onychiurus cebennarius, Mesaphorura macrochaeta, Folsomia fimetaria, Proisotoma minuta and Orchesella villosa. Faeces were collected from all species. Only faeces from M. macrochaeta did not contain teliospores. Ingestion by the four other collembolan species reduced germination rates of T. tritici teliospores from 76.5% in the control to below 3% after ingestion. There were no significant differences between the germination rates after ingestion by the different collembolan species. Two soil types, a sphagnum based potting medium and a coarse sandy field soil, were inoculated with 0.1, 0.2 or 0.3 mg of teliospores, and incubated with 15  F. fimetaria or P. minuta...

Eine der bedeutendsten Erkrankungen in der Milchviehherde ist die Euterentzündung. Die Ursachen der Mastitis sind vielfältig. Daher muss diesem Krankheitskomplex ein ganzheitliches Konzept entgegengesetzt werden.    Um von einer Euterentzündung sprechen zu können, müssen Erscheingungen wie Rötung, Schwellung, Schmerz, vermehrte Wärme oder Abweichungen im Aussehen oder der Zusammensetzung der Milch vorliegen. Ist mindestens eines der angegebenen Symptome mit den fünf Sinnen des Menschen ohne Hilfmittel zu erkennen, spricht man von einer klinischen Euterentzündung (eine Flocke im Vorgemelk = klinische Mastitis!). Von größerer Bedeutung sind jedoch die weniger offensichtlichen Erkrankungen, die so genannten chronisch subklinischen oder unspezifischen...

The organic seed regulations framework in Europe – current status and recommendations for future development
Provedor de dados: 21
Autores: Döring, Thomas F.; Bocci, Riccardo; Hitchings, Roger; Howlett, S. A.; Lammerts van Bueren, E.T.; Pautasso, Marco; Raaijmakers, M; Rey, F; Stubsgaard, Anke; Weinhappel, M.; Wilbois, Klaus-Peter; Winkler, Louisa; Wolfe, M S.
Organic agriculture regulations, in particular European regulation EC 889/2008, prescribe the use of organically produced seed. For many cultivated plants, however, organic seed is often not available. This is mainly because investment in organic plant breeding and seed production has been low in the past. To bridge the gap between organic seed supply and demand, national and European regulations define certain circumstances under which organic producers are permitted to use non-organically produced seed. While the organic sector currently depends on these concessions, they also threaten to impede a further increase in the demand for organic seed, thereby potentially restraining present and future investment in organic seed production and plant breeding....

Common Couch-grass control with less tillage
Provedor de dados: 21
Autores: Melander, Bo; Rasmussen, Ilse A; Bertelsen, Inger.
Control of Common Couch-grass often conflicts with the need to retain nutrients in organic cropping systems, as it involves intensive tillage in the post-harvest period. Thus, preferably the soil should be cropped through the entire year to prevent nutrient leaching from the root zone. Research has shown that new control strategies may combine the reduction of couch infestations and a soil cover with plants during the post-harvest period. This may have potential for practical implementation.

Extracts from a History of the Organic Agriculture Movement in Australia
Provedor de dados: 21
Autores: Paull, John.
Australia’s involvement in the organic movement has proceeded in four district waves of activity. The First Wave (1920s &amp; 1930s) was that of the Australian anthroposophists who joined Rudolf Steiner’s Agricultural Experimental Circle of Anthroposophic Farmers and Gardeners and culminated with the ‘coming out’ of biodynamic agriculture in 1938 with Ehrenfried Pfeiffer’s book Bio-Dynamic Farming and Gardening and in Australia with Bob Williams presenting the first public lecture on biodynamics at the home of Walter Burley and Marion Mahoney Griffin. The Second Wave of organic agriculture in Australia (1940s &amp; 1950s) is anchored by the coining of the term ‘organic farming’ in 1940, in England and it saw the founding of the first associations in...

Climate change and prolongation of growing season: changes in regional potential for field crop production in Finland
Provedor de dados: 21
Autores: Peltonen-Sainio, Pirjo; Jauhiainen, Lauri; Hakala, Kaija; Ojanen, Hannu.
Climate change offers new opportunities for Finnish field crop production, which is currently limited by the short growing season. A warmer climate will extend the thermal growing season and the physiologically effective part of it. Winters will also become milder, enabling introduction of winter-sown crops to a greater extent than is possible today. With this study we aim to characterise the likely regional differences in capacity to grow different seed producing crops. Prolongation of the Finnish growing season was estimated using a 0.5º latitude × 0.5º longitude gridded dataset from the Finnish Meteorological Institute. The dataset comprised an average estimate from 19 global climate models of the response of Finnish climate to low (B1) and high (A2)...

Field Simulation of Transgenic Seed Admixture Dispersion in Maize with a Blue Kernel Color Marker
Provedor de dados: 21
Autores: Dietiker, Dominique; Oehen, Bernadette; Ochsenbein, Christian; Westgate, Mark E.; Stamp, Peter.
Seed purity in maize (Zea mays L.) has been almost neglected in coexistence studies. In this study, the impact of initial seed admixture was assessed in 20 fields (17 integrated pest management [IPM] and three organics) in the Swiss Midlands in 2007 and 2008 and a seed admixture threshold was proposed. The bluekernelled French hybrid Adonis was used as a color-marker admixture. In 2009, its pollen production was assessed relative to those of two commercial hybrids (LG 32.12 and DKC 2960) that released 41 and 62%, respectively, less pollen than Adonis. Adonis was added to commercial yellow hybrid seeds at a proportion of 1:99. On average, the seed admixture at harvest was 2.8 times greater than the seed admixture at sowing. The greater pollen production of...

Mapping of common bunt resistance gene Bt9 in wheat
Provedor de dados: 21
Autores: Steffan, Philipp; Torp, Anna-Maria; Borgen, Anders; Backes, Gunter.
Increasing organic wheat production in Denmark, and in other wheat-producing areas, in conjunction with legal requirements for organic seed production, may potentially lead to a rise in common bunt occurrence. As systemic pesticides are not used in organic farming, organic wheat production systems may benefit from genetic resistances. However, little is known about the underlying genetic mechanisms and locations of the resistance factors for common bunt resistance in wheat. A double haploid (DH) population segregating for common bunt resistance was used to identify the chromosomal location of common bunt resistance gene Bt9. DH lines were phenotyped in three environments and genotyped with DArTseq and SSR markers. The total length of the resulting linkage...

There is an urgent need to identify and evaluate management practices for their biophysical potential to maintain productivity under climate change while mitigating greenhouse gas (GHG) emissions from individual cropping systems under specific pedo-climatic conditions. Here, we examined, through DayCent modeling, the long-term impact of soil management practices and their interactions on soil GHG emissions and GHG intensity from Swiss cropping systems. Based on experimental data from four long-term experimental sites in Switzerland (Therwil, Frick, Changins, and Reckenholz), we robustly parameterized and evaluated the model for simulating crop productivity, soil C dynamics and soil N2O emissions across a range of management practices and pedo-climatic...

Transmission dynamics of Ascaris suum in Danish organic pig farms
Provedor de dados: 21
Autores: Katakam, Kiran Kumar; Thamsborg, Stig Milan; Dalsgaard, Anders; Mejer, Helena.
Although Ascaris suum is the most common nematode in pig farms, the on-farm transmission dynamics is not well described. Hence we performed a 1-year field study on organic pig farms, mapping egg contamination levels in pens and on pastures (dry sows, lactating sows and starters) and infection levels in animals. In conclusion, recovery of infective eggs was limited in deep litter compared to shallow litter, but many deep litter eggs were still viable.  A. suum transmission takes place both indoors and outdoors. Highly infective bedding material should be stored, composted or treated before spreading on crops and never used for pastures.

Functional agrobiodiversity and agroecosystem services in sustainable wheat production. A review
Provedor de dados: 21
Autores: Costanzo, Ambrogio; Bàrberi, Paolo.
Agrobiodiversity can improve the sustainability of cropping systems in a context of low external inputs and unpredictable climate change. Agrobiodiversity strategies to grow wheat are breeding ad hoc cultivars for organic and low-input systems, wheat–legume intercrops and living mulches, cultivar mixtures, and the use of genetically heterogeneous populations. However, applying those strategies can fail due the lack of a well-focused framework. Therefore, we need a better integration between breeding and management and a clear focus on crop traits related to key agroecosystem services. Here, we review the use of agrobiodiversity in wheat production, focusing on breeding and management. We discuss five agroecosystem services: (1) weed reduction, (2) nitrogen...

On his final visit to Britain, Rudolf Steiner delivered three lectures a day during the Anthroposophical Society’s Summer School at Torquay (11-22 August 1924). Steiner took one day out of this hectic schedule to be a tourist for a day. The decision took him as far west as he ever ventured in his lifetime - to Tintagel on the west cost of Cornwall. The Tintagel visit occurred just two months after Steiner’s Agriculture Course and less than six weeks before Rudolf Steiner retreated from public life entirely. On this, his tenth visit to Britain, Steiner lectured on Anthroposophy and Waldorf education. The opportunity for agriculture lectures in Britain never arose, and there had been no Anglo attendees at the Koberwitz course. However, the Tintagel day trip...

Although organic beef marketing has long lagged behind that of organic products of plant origin, it has grown considerably since the late 1990s, when the large retailers entered the market. Whereas in 2000-2001 the value of the Australian certified organic beef was only $32 million (farm-gate prices), with less than two thirds going to the organic market, by 2005 the estimated production had doubled to around $60 million (farm-gate prices), with virtually all of the produce being sold in the organic market. About three quarters of this is currently sold through the domestic market. Dominant export markets have moved from Japan and the UK to the USA.

Discrimination of semi-natural plant communities from abandoned fields by ordination and neural networks
Provedor de dados: 21
Autores: Ejrnæs, Rasmus; Liira, Jaan; Poulsen, Roar S.
This study deals with the succession from abandoned fields to semi-natural grassland and heathland vegetation and the discrimination between these types of habitat. We hypothesise that semi-natural condition may be indicated by species lists of vascular plants. A statistical classification model is developed, based on 2059 reference samples from Danish ancient grasslands and heathlands, and abandoned fields of varying age. This Succession Model is shown to discriminate effectively between abandoned fields and semi-natural habitats, and it is suggested to be useful for the detection of conservation-worthy abandoned fields. A test of four hypotheses regarding the model prediction of naturalness of abandoned fields revealed that successional age, period of...

Strip cropping of alternating perennial grass-clover and annual rye - vetch intercrops when grown within an organic farming system
Provedor de dados: 21
Autores: Hauggaard-Nielsen, Henrik; Johansen , Anders; Carter, Mette S.; Ambus, Per; Jensen, Erik Steen.
A field experiment was carried out including alternating perennial ryegrass (Lolium perenne L.) – clover (Trifolium repens + Trifolium pretense L.) pasture mix with annual vetch (Vicia villosa L.) – winter rye (Secale cereale L.) intercrops. The annuals were established after soil incorporation of a 1st-year grass-clover in a 6-m wide strip, whereas the perennials were established without incorporating the 1st-year grass-clover in an equivalent 6-m wide strip. This resulted in an early interspecific competitive advantage for the perennial strip and especially limiting growth of the rye component. Relative clover proportion in the sward increased with increasing distance to the annual strip indicating more available soil mineral N in the interface between...

Production of trichothecenes and other secondary metabolites by Fusarium culmorum and F. equiseti on common laboratory media and a soil organic matter agar: An ecological interpretation
Provedor de dados: 21
Autores: Hestbjerg, Helle; Nielsen, Kristian F.; Thrane, Ulf; Elmholt, Susanne.
Fusarium culmorum and F. equiseti were characterized with regard to production of trichothecenes and other secondary metabolites. Results following growth on laboratory media are interpreted with the aim of increasing the understanding of fungal metabolism in the field environment. While trichothecene production was detected for 94 of 102 F. culmorum isolates, only eight of 57 F. equiseti isolates were positive. Profiles of secondary metabolites were compared following growth on Yeast Extract Sucrose agar (YES), Potato Sucrose Agar (PSA) and an agar medium, prepared from Soil Organic Matter (SOM), which was included to simulate growth conditions in soil. SOM supported the production of chrysogine by F. culmorum. The two species utilized the media...

Managing soil carbon for climate change mitigation and adaptation in Mediterranean cropping systems: A meta-analysis
Provedor de dados: 21
Autores: Aguilera, Eduardo; Lassaletta, Luis; Gattinger, Andreas; Gimeno, Benjamín S.
Mediterranean croplands are seasonally dry agroecosystems with low soil organic carbon (SOC) content and high risk of land degradation and desertification. The increase in SOC is of special interest in these systems, as it can help to build resilience for climate change adaptation while contributing to mitigate global warming through the sequestration of atmospheric carbon (C). We compared SOC change and C sequestration under a number of recommended management practices (RMPs) with neighboring conventional plots under Mediterranean climate (174 data sets from 79 references). The highest response in C sequestration was achieved by those practices applying largest amounts of C inputs (land treatment and organic amendments). Conservation tillage practices...

Prevalence of Anaplasma phagocytophilum infection and effect on lamb growth
Provedor de dados: 21
Autores: Grøva, Lise; Olesen, Ingrid; Steinshamn, Håvard; Stuen , Snorre.
Background: A major challenge in sheep farming during the grazing season along the coast of south-western  Norway is tick-borne fever (TBF) caused by the bacteria Anaplasma phagocytophilum that is transmitted by the tick  Ixodes ricinus.  Methods: A study was carried out in 2007 and 2008 to examine the prevalence of A. phagocytophilum infection  and effect on weaning weight in lambs. The study included 1208 lambs from farms in Sunndal Ram Circle in Møre  and Romsdal County in Mid-Norway, where ticks are frequently observed. All lambs were blood sampled and  serum was analyzed by an indirect fluorescent antibody assay (IFA) to determine an antibody status (positive or  negative) to A. phagocytophilum infection.

Predicting grain yield and protein content in winter wheat and spring barley using repeated canopy reflectance measurements and partial least squares regression
Provedor de dados: 21
Autores: Hansen, P.M.; Jørgensen, J.R.; Thomsen, A.
By providing both spatial and temporal information remote sensing may function as an important source of data for site-specific crop management. This technology has been used for nitrogen application strategies to obtain optimum yield and grain quality. Here, the objective was to use early repeated remotely sensed multi-spectral data to predict grain yield and quality for winter wheat (Triticum aestivum L.) and spring barley (Hordeum vulgare L.). The crops were sown with two different seeding rates and a wide range of nitrogen strategies were applied. Multi-way partial least squares regression (N-PLS) was used to predict grain yield and protein content. The results were compared with unfold-PLS1 and PLS1 using reflectance data from the last measurement...

EFFECTS OF ANAEROBIC DIGESTION AND SEPARATION OF PIG SLURRY ON ODOR EMISSION
Provedor de dados: 21
Autores: Hansen, Martin N.; Kai, Peter; Møller, Henrik B.
Storage and land application of livestock manure causes considerable odor nuisance to the surrounding neighborhood. Anaerobic digestion and separation of slurry change composition and physical properties of slurry and may therefore lessen the odor pollution during storage and land application. An experiment was set up to study the effects of anaerobic digestion and separation of slurry on the emission of odor. Odor concentration above treated and untreated slurry was compared during storage and following land application using GC/MS analysis and dynamic dilution olfactometry. Slurry concentrations of malodorous volatile fatty acids were reduced by between 79 to 97% by anaerobic digestion, while concentrations of malodorous phenolic and indolic odor...

Long term farming systems affect soils potential for N2O production and reduction processes under denitrifying conditions
Provedor de dados: 21
Autores: Krause, Hans-Martin; Thonar, Cécile; Eschenbach, Wolfram; Well, Reinhard; Mäder, Paul; Behrens, Sebastian; Kappler, Andreas; Gattinger, Andreas.
N2O is a potent greenhouse gas with an atmospheric lifetime of 114 years which also contributes to ozone layer destruction. Mitigating N2O emissions is especially challenging to the agricultural sector that is responsible for the majority of anthropogenic N2O release. In order to develop effective mitigation strategies, a detailed understanding of drivers for N2O production and reduction in agriculturally managed soils is needed. Denitrification is recognized as one of the most important source processes for N2O emissions from soils. However, the last step in denitrification, the reduction of N2O to N2 is the only known sink for N2O in soil. Although the impact of single parameters on denitrification is quite well documented, there is still a knowledge gap...

Flavone C-glycosides, phenolic acids and nitrogen content in leaves of barley subject to organic fertilization treatments
Provedor de dados: 21
Autores: Nørbæk, R.; Folsted, D.; Bleeg, I.S.; Christensen, B.T.; Brandt, K.; Kondo, T.
From the leaves of barley, Hordeum vulgare, one new flavone C-glucoside and three known flavone glucosides were isolated and characterized by 1H, 13C NMR and MALDITOF-MS. The novel flavone C-glucoside was isovitexin 7-O-b-(6’’’-O-(E)-p-coumaroyl)glucoside and the known compounds were isovitexin 7-O-b-(6’’’-O-(E)-feruloyl)glucoside, isoorientin 7-O-b-(6’’’-O-(E)-feruloyl)glucoside and tricin 7-O-b-glucoside. The sum of all the flavone glycosides and soluble phenolic acids in the leaves decreased with increased rate of plant nutrients given in animal manure and with increased crop yield. All major phenylpropanoids showed the same general response to nutrient level. The concentration of nitrogen in the leaves was not directly related to nutrient application...

Biodegradability screening of soil amendments through coupling of wavelength-scanned cavity ring-down spectroscopy to multiple dynamic chambers
Provedor de dados: 21
Autores: Bai, Mo; Köstler, Martin; Kunstmann, Jürgen; Wilske, Burkhard; Gattinger, Andreas; Frede, Hans-Georg; Breuer, Lutz.
A system was developed for the automatic measurements of 13CO2 efflux to determine biodegradation of extra carbon amendments to soils. The system combines wavelength-scanned cavity ring down laser spectroscopy (WS-CRDS) with the open-dynamic chamber (ODC) method. The WS-CRDS instrument and a batch of 24 ODC are coupled via microprocessor-controlled valves. Determination of the biodegradation requires a known d13C value and the applied mass of the carbon compounds, and the biodegradation is calculated based on the 13CO2 mixing ratio (ppm) sampled from the headspace of the chambers. The WS-CRDS system provided accurate detection based on parallel samples of three standard gases (13CO2 of 2, 11 and 22 ppm) that were measured simultaneously by isotope ratio...

Autores: Pommeresche, Reidun; Løes, Anne-Kristin; Torp, Torfinn.
The density and diversity of springtails (Collembola) in the upper soil layer (0–3.8 cm) were studied in a perennial grass-clover ley in NW Norway during April–June 2012. The study was part of a field experiment comparing yields and soil characteristics after application of non-digested slurry (NS) versus anaerobically digested slurry (DS) from dairy cows. In total for three sampling dates, 39 species of springtails were identified. In the Control plots receiving no manure, the density level was around 30 000 individuals (ind.) m2 throughout the whole season. Three days after slurry application (40 t ha -1), the density of springtails had dropped significantly; from 55 214 to 7410 ind. m2 in the NS treatment and from 41 914 to 10 260 ind. m2 in the DS...

The effect of the organic production system on broiler carcass and meat quality was assessed. Two hundred and fifty Ross male chickens were assigned to two different systems of production: conventional, housing in an indoor pen (0.12 m2/bird); organic, housing in an indoor pen (0.12 m2/bird) with access to a grass paddock (4 m2/bird). At 56 and 81 days of age twenty chickens per group were slaughtered to evaluate the carcass traits and the characteristics of breast and drumstick muscles (pectoralis major and peroneus longus). The organic chickens had carcasses with a higher breast and drumstick percentages and lower level of abdominal fat. The muscles had lower pHu and water holding capacity.

Nutrient availability affects carbon turnover and microbial physiology differently in topsoil and subsoil under a temperate grassland
Provedor de dados: 21
Autores: Liang, Zhi; Olesen, Jørgen E.; Jensen, Johannes L.; Elsgaard, Lars.
Increasing subsoil organic carbon inputs could potentially mitigate climate change by sequestering atmospheric CO2. Yet, microbial turnover and stabilization of labile carbon in subsoils are regulated by complex mechanisms including the availability of nitrogen (N), phosphorous (P), and sulfur (S). The present study mimicked labile organic carbon input using a versatile substrate (i.e. glucose) to address the interaction between carbon-induced mineralization, N-P-S availability, and microbial physiology in topsoil and subsoils from a temperate agricultural sandy loam soil. A factorial incubation study (42 days) showed that net losses of added carbon in topsoil were constant, whereas carbon losses in subsoils varied according to nutrient treatments. Glucose...

Autores: Arncken, Christine; Mäder, Paul; Mayer, Jochen; Weibel, Franco P.
BACKGROUND: Consumers expect organic produce to have higher environmental, health and sensory related qualities than conventional produce. In order to test sensory differences between bio-dynamically, bio-organically and conventionally grown winter wheat (Triticum aestivum L., cv. Runal), we performed double-blinded triangle tests with two panels on dry wholemeal flour from the harvest years 2006, 2007 and 2009 and from two field replicates of the ‘DOK’ long-term farming system comparison field trial near Basel, Switzerland. Yield and quality parameters were also assessed.  RESULTS: Significant farming system effects were found for yield (up to 42% reduction in the organic system), thousand kernel weight, hectolitre weight and crude protein content across...

Improved field margins highly increase slug activity  in Switzerland
Provedor de dados: 21
Autores: Eggenschwiler, Lisa; Speiser, Bernhard; Bosshard, Andreas; Jacot, Katja.
Most field margins on arable land in Switzerland are narrow and intensively managed. As a consequence, field margins generally harbour few plant and animal species. To enhance biodiversity in arable landscapes, sown species-rich field margins, so-called improved field margins, were introduced in 2008 as a part of the Swiss agri-environment scheme. Here, we tested whether improved field margins increase slug activity density. Slug activity density in and next to improved field margins was compared to slug activity in and next to conventional field margins. Over a period of 3 years, slugs were sampled in three regions in northern Switzerland in late spring using bait stations. Our results show that improved field margins have higher slug activity density, of...

The emissions of nitrous oxide (N2O) and leaching of nitrate (NO3) from agricultural cropping systems have considerable negative impacts on climate and the environment. Although these environmental burdens are less per unit area in organic than in non-organic production on average, they are roughly similar per unit of product. If organic farming is to maintain its goal of being environmentally friendly, these loadings must be addressed. We discuss the impact of possible drivers of N2O emissions and NO3 leaching within organic arable farming practice under European climatic conditions, and potential strategies to reduce these. Organic arable crop rotations are generally diverse with the frequent use of legumes, intercropping and organic fertilisers. The...

Analysis of the distribution of organic farming and its determinants is a major challenge for the construction of scenarios related to the evolution of organic farming that take the set of factors that limit or facilitate conversions and their sustainability into account. In order to support different development scenarios for organic farming in view of environmental and marketing challenges, an econometric and geostatistic study was initiated in the PACA region. The approach consists of three stages. The first stage involves the construction, over a 20-year period, of a longitudinal spatial database concerning certified organic producers and distributors. This database is georeferenced at the plot level. It will then be necessary to statistically analyse...

Assessing varietal resistances to control common wheat bunt under organic cereal production and soft wheat, in particular
Provedor de dados: 21
Autores: FONTAINE, L.; du CHEYRON, P.; MORAND, P.; SKIKERS, S.
Common wheat bunt (caused by the fungus Tilletia caries or Tilletia foetida) is a disease whose incidence is clearly on the rise in organic farming, jeopardising the balance of the French organic cereal sector. Control methods adapted to organic farming must be found, especially since we know that no seed treatment is 100% effective. The use of varietal resistance appears particularly promising for limiting the spread of the disease. Since 2000, an experiment whose purpose is to assess the resistance of soft wheat varieties to Tilletia caries is conducted each year by the French plant institute, ARVALIS. These experiments make it possible to identify the existence of a wide behavioural variability with respect to this pathogen among the different varieties...

O artigo analisa entraves para a transição agroecológica e adequação às normas de certificação orgânica, em unidades familiares produtoras de leite, a partir do caso de uma central de cooperativas de agricultores familiares, a qual possui 73 propriedades em transição. Os principais entraves identificados derivam da ausência de alternativa para venda do leite orgânico, do desconhecimento dos agricultores sobre normas e técnicas específicas para a produção orgânica, e da falta de apoio técnico e organizacional para geração de alternativas que seriam difíceis de implementar à escala de uma só unidade produtiva. Conclui-se que a precariedade da transição agroecológica colocaria os agricultores em risco, caso se aplicasse com rigor a legislação para a produção...

Codigestion of manure and organic waste at centralized biogas plants: process imbalances and limitations
Provedor de dados: 21
Autores: Nielsen, H.B.; Angelidaki, I.
The present study focuses on process inhibitions in Danish centralized biogas plants. Collection of data from the plants and a number of interviews showed that inhibitions occur frequently. High concentrations of ammonia, long chain fatty acids or other inhibitory compounds, and foaming in prestorage tanks are well known causes of inhibition. These problems mainly occurs due to: 1) inadequate knowledge about the waste composition and 2) its degradation characteristics, 3) inadequate process surveillance especially with regard to volatile fatty acids and 4) insufficient pre-storage capacity causing inexpedient mixing of the different waste products in the pre-storage tanks.

Auswirkungen reduzierter Hofdüngergaben im Bioackerbau
Provedor de dados: 21
Autores: Dubois, David; Mäder, Paul; Fliessbach, Andreas; Strasser, Fredi.
Im Biolandbau ist das Idealbild eines gemischt wirtschaftenden Betriebes mit Vieh und Pflanzenbau weit verbreitet. Aus wirtschaftlichen Zwängen wird der Trend zu viehschwachen oder gar viehlosen Biobetrieben immer wichtiger. Untersuchungen der FAL und des FiBL im DOK-Versuch zeigen, dass sich, wenn die Bewirtschaftung nicht angepasst wird, die Reduktion der Hofdüngergaben ungünstig auf Ertrag, Unkrautbesatz und Bodenfruchtbarkeit auswirkt.

Health and cost implications of choosing an organic diet - empirical insights from Danish household panel data
Provedor de dados: 21
Autores: Denver, Sigrid; Christensen, Tove.
Health and cost considerations have repeatedly been found to constitute the main arguments for respectively buying and not buying organic food. The present paper contributes to this line of research by studying not only the dietary but also the budgetary consequences of choosing the organic varieties. Using purchase data for a large sample of Danish households, we found that households with higher organic consumption have healthier diets as measured in terms of more vegetables and fruits but less fat/confectionary and meat. Furthermore, for the vast majority of households it was found that buying organic foods did not increase food expenditures - possibly due to differences in diet composition. The key to these findings lies in the adoption of a holistic...

Influence of chicory roots (Cichorium intybus L) on boar taint in entire male and female pigs
Provedor de dados: 21
Autores: Hansen, L.L.; Mejer, H.; Thamsborg, S.M.; Burne, D.V.; Roepstorff, A.; Karlsson, A.H.; Hansen-Møller, J.; Jensen, M.T.; Tuomola, M.
Boar taint is an off-flavour of pork caused primarily by a microbial breakdown product, skatole and a testicular steroid, androstenone. As skatole is produced in the large intestine from tryptophan, it is possible that some "bioactive" ingredients could modify protein fermentation and, in the process, diminish boar taint. The aim of this study was to examine the effect of inulin-rich chicory roots (Cichorium intybus L.) on boar taint. In the first of three trials individually penned, entire males and females were given an organic concentrate in which 0·25 of the daily energy intake was replaced with crude chicory roots for 9 or 4 weeks prior to slaughter. In the second trial, entire male pigs were given diets that included, either crude chicory roots,...

Autores: De Cock, Lieve; Taragola, Nicole; Dessein, Joost; Crivits, Maarten.
Networks are considered to gain potential for supporting  innovation. To understand how networks can maximally support the grower’s innovation process, a conceptual framework was constructed based on five dimensions: (i) creative idea generation, (ii) knowledge assemblage, (iii) learning process, (iv) coalition building and (v) institutional innovation. This paper explores how recently established networks for creating and exchanging knowledge in organic horticulture in Flanders can contribute to the innovation capacity of the organic horticultural community. Our analysis shows that each network has its rationality and assists its members, the organic grower and the organic sector as a whole, directly or indirectly, during their innovation process. The...

Autores: Bennedsgaard, Torben Werner; Klaas, I.C.; Vaarst, M.
With the aim of phasing out the use of antimicrobials 23 Danish organic dairy producers from the same organic dairy company participated in Stable School farmer groups from February 2004 to March 2005 in order to go through a common learning and development process towards their common goal. Data on production and herd health were evaluated from two years before to three years after the start of the Stable Schools. For comparison, data was collected from the remaining 35 herds delivering to the same dairy company, 118 organic dairy herds delivering to other dairies and 115 conventional herds. On average, the project herds were smaller with lower production and had half the incidence rate of mastitis treatment than the organic herds from other dairies...

Importance of growth characteristics for yield of barley in different growing systems: will growth characteristics describe yield differently in different growing systems?
Provedor de dados: 21
Autores: Kristensen, Kristian; Ericson, Lars.
The interest in organic grown cereals has increased the need for variety tests under organic growing systems and/or the knowledge on whether growth characteristics describe yield differently under conventional and organic conditions. This paper is a contribution to that question by examining the relationships between some important growth characteristics in barley trials in both systems in Northern Sweden and in Denmark. Mixed model analyses were used for regressions of growth characteristics (or transformations of those) on yield (and log-transformed yield), allowing the slope to depend on the growing system.  The analyses showed that diseases seemed to have a less negative effect on yield in the organic growing system than in the conventional growing...

Co-production of ethanol, biogas, protein fodder and  natural fertilizer in organic farming – evaluation of a  concept for a farm-scale biorefinery
Provedor de dados: 21
Autores: Oleskowicz-Popiel, Piotr; Kádár, Zsófia; Heiske, Stefan; Klein-Marcuschamer , D.; Simmons, Blake A.; Blanch, Harvey W.; Schmidt, Jens Ejbye.
The addition of a biorefinery to an organic farm was  investigated, where ethanol was produced from germinated   rye grains and whey, and the effluent was separated into two streams: the protein-rich solid fraction, to be used as animal feed, and the liquid fraction, which can be co-digested with clover grass silage to produce biogas. A method for ethanol production from rye was applied by utilizing inherent amylase activity from germination of the seed. Biogas potential of ethanol fermentation effluent was   measured through anaerobic digestion trials. The effluent from the trials was assumed to serve as natural fertilizer. A technoeconomic analysis was also performed; total capital investment was estimated to be approximately 4 M USD. Setting a methane...

A new concept for the control of Elytrigia repens in organic crop production
Provedor de dados: 21
Autores: Melander, Bo; Nørremark, Michael; Fløjgaard, Erik.
The control of perennial weeds in organic crop production needs reconsideration to minimise losses of nutrients through leaching. Long post-harvest periods with mechanical weed control hinder a plant cover with the purpose of taking up nutrients not being utilised by the main crop to maintain soil fertility. To meet the interests of nutrient and weed management, we suggest a new concept for the control of perennial weeds with propagules placed within the plough layer. The concept comprises uprooting and immediate removal of Elytrigia repens rhizomes with modified machinery to allow for a quick re-establishment of a plant cover to avoid longer periods of bare soil. Four passes with a modified cultivator where each pass was followed by rhizome removal and...

Conservation practices are important in improving the environmental protection of agroecosystems in semiarid regions, as these are considered to be fragile environments. Soil-quality indicators are useful elements in evaluating the impact of some agricultural management practices, and the use of recognized indicators which are able to be measured by farmers is an innovative approach that seeks to integrate both scientific and local knowledge. This study aimed to evaluate the impact of various management practices through indicators of soil quality related to soil structure, in areas of family farming where agroecological consortiums are employed. These indicators were identified as important by the farmers themselves, and methodologies were suggested for...

The popularity of organic food and the farming area managed according to organic agriculture practices have been increasing during the last years. It is not clear, whether foods from organic and conventional agriculture are equal with respect to nutritional quality. We chose wheat (Triticum aestivum L., cv. Titlis) as one of the most important crop plants to determine a range of substances relevant for human nutrition in crops from organic and conventional agriculture systems. Wheat grains of 2003 originating from a long term field experiment, the Swiss DOK trial, consisting of bio-dynamic, bio-organic and conventional farming systems were used.

Nitrate leaching in an organic dairy/crop rotation as affected by organic manure type, livestock density and crop.
Provedor de dados: 21
Autores: Eriksen, J; Askegaard, M; Kristensen, K.
In dairy farming systems the risk of nitrate leaching is increased by mixed rotations (pasture/arable) and the use of organic manure. We investigated the effect of four organic farming systems with different livestock densities and different types of organic manure on crop yields, nitrate leaching and N balance in an organic dairy/crop rotation (barley – grass-clover – grass-clover – barley/pea – winter wheat – fodder beet) from 1994 until 1998. Nitrate concentrations in soil water extracted by ceramic suction cups ranged from below 1 mg NO3-N/l in 1st year grass-clover to 20-50 mg NO3-N/l in the winter following barley/pea and winter wheat. Peaks of high nitrate concentrations were observed in 2nd year grass-clover, probably due to urination by grazing...

Autores: Hein, Lisa; Sørensen, Lars Peter; Kargo, Morten; Buitenhuis, Albert Johannes.
The objective of this study was to assess the genetic variability of the detailed fatty acid (FA) profiles of Danish Holstein (DH) and Danish Jersey (DJ) cattle populations. We estimated genetic parameters for 11 FA or groups of FA in milk samples from the Danish milk control system between May 2015 and October 2016. Concentrations of different FA and FA groups in milk samples were measured by mid-infrared spectroscopy. Data used for parameter estimation were from 132,732 first-parity DH cows and 21,966 first-parity DJ cows. We found the highest heritabilities for test day measurements in both populations for short-chain FA (DH = 0.16; DJ = 0.16) and C16:0 (DH = 0.14; DJ = 0.16). In DH, the highest heritabilities were also found for saturated FA and...

Disconnection of the ‘organic’ food production from the ‘organic network’? - A Danish actor network case study
Provedor de dados: 21
Autores: Noe, Egon.
The Danish case of organic agriculture is generally regarded as a success story. But the enrolment of new actors and the growing economic interest may lead to a change of the ideological foundation of organic agriculture. The scope of this paper is to explore what happens to organic agriculture through the process of dissemination of the organic mode of farming and enrolment of conventional farmers into organic farming from an Actor Network Theory (ANT) approach. This is explored through an in-depth case study of the local development and dissemination processes of organic farming. 11 organic farmers and two local advisors were interviewed. The narratives of the local organic network give the outlines to three phases in the network building. 1) The pioneer...

Anbauversuche der letzten Jahre in Forschung und Praxis zeigen jedoch: Unter Regenschutz und mit Totaleinnetzung lassen sich Biokirschen ertragssicher und wirtschaftlich produzieren. Auch mit den heute gefragten grossfruchtigen Sorten.

Differences in Yield Parameters of Emmer in Comparison with Old and New Varieties of Bread Wheat
Provedor de dados: 21
Autores: Petr, Konvalina; Ivana, Capouchová; Zdeněk, Stehno; Jan, Moudry.
Emmer wheat (Triticum diccocum Schrank) belonged to the most frequent species of cereals in the past. Nowadays, it is grown in arid and montane areas in particular. Interest in this cereal species has increased, as it is tolerant to biotic and abiotic stressing factors. Therefore, yield parameters were evaluated in three-year (2007, 2008 and 2010) trials that were carried out in two different localities in the Czech Republic. Results of the research were compared to characteristics of four old and two top  modern bread wheat (Triticum aestivum L.) cultivars. The emmer wheat varieties were resistant to usual wheat diseases. They formed their yield by a quantity of productive tillers (2.5), whereas the varieties of bread wheat had less productive tillers...

The Bio-Economy Concept and Knowledge Base in a Public Goods and Farmer Perspective
Provedor de dados: 21
Autores: Schmid, Otto; Padel, Susanne; Levidov, Les.
Currently an industrial perspective dominates the EU policy framework for a European bio-economy. The Commission’s proposal on the bio-economy emphasises greater resource-efficiency, largely within an industrial perspective on global economic competitiveness, benefiting capital-intensive industries at higher levels of the value chain. However a responsible bio-economy must initially address the sustainable use of resources. Many farmers are not only commodity producers but also providers of quality food and managers of the eco-system. A public goods-oriented bio-economy emphasises agro-ecological methods, organic and low (external) input farming systems, ecosystem services, social innovation in multi-stakeholder collective practices  and joint production...

Comparing the Effect of Continuous Drying and Drum Drying on Fungal Contamination of Bread Grain
Provedor de dados: 21
Autores: Elmholt, S.; Kristensen, E.F.; Thrane, U.
This Research Note concludes that both drum drying and ordinary continuous drying efficiently dry the grain but that drum drying is much more efficient in reducing the number of surface dwelling fungal propagules on the grain, both yeasts and filamentous fungi. This includes the toxigenic species, Fusarium culmorum, as well as other fusaria. It also includes the dark filamentous fungi, Alternaria infectoria and Cladosporium spp. Both drying techniques seemed to stimulate growth of Eurotium spp., probably due to heat activation of ascospore germination.

Crop cover improves the nitrogen status in vegetable crop rotations
Provedor de dados: 21
Autores: Thorup-Kristensen, Kristian.
Results from an organic vegetable rotation, and from a number of specific experiments with catch crops, shows that autumn crop cover strongly improves N availability for the succeeding crop. Though many different types of crop cover have been involved, from full year green manures, to short term catch crops and green manures and even white cabbage stubble allowed to continue growth after harvest, they have all had a similar effect on N dynamics in the field. With crops actively growing in the field until the late autumn, much less N is left in the soil, and the risk of leaching loss is strongly reduced. In the subsequent spring, mineralization of N from the crop residues leads to increased N availability for the succeeding crop. This main effect was found...

Colza – La discipline reine des grandes cultures bio
Provedor de dados: 21
Autores: Daniel, C.; Dierauer, H.; Schärer, F.; Ramseier, H.; Bovigny, C.; Jossi, W.; Humphrys, C.
La culture du colza est risquée mais intéressante: elle permet de réaliser une marge brute aussi élevée qu’avec du blé. Et la demande d’huile de colza pressée à froid est nettement supérieure à l’offre. Les temps sont donc favorables pour ceux qui – bien préparés – désirent s’attaquer à la «discipline reine» des grandes cultures biologiques.  Depuis 2005, la surface des cultures biologiques de colza a passé en Suisse de 5 à 150 hectares. Une histoire à succès qui continue: les coopératives Biofarm et PROGANA cherchent de nouveaux producteurs pour couvrir la demande durablement forte d’huile de colza biologique pressée à froid.

Ökolandbau-Hemmnisse für die Umstellung
Provedor de dados: 21
Autores: Stolze, Matthias.
Die vorgestellten Überlegungen zur Situation des ökologischen Landbaus in Deutschland anhand des Erklärungsmodells von Michelsen et al. (2001) zeigen insgesamt, dass Deutschland in den Bereichen 1 bis 3 (Etablierung eines unabhängigen Öko-Sektors, Politische Initiativen hinsichtlich Richtlinien und Kontrollen, Staatliche Transferzahlungen für den ökologischen Landbau) gute Voraussetzung für die Ausdehnung des ökologischen Landbaus aufweist. Die nähere Auseinandersetzung zeigt aber auch deutlich, dass in allen drei Bereichen Defizite herrschen, die der Entwicklung des Öko-Landbaus entgegen stehen.   Aus Verbrauchersicht ist insbesondere das Fehlen eines einheitlichen und im Lebensmittelmarkt weit verbreiteten Kennzeichens für Öko-Produkte sowie die...

Open access publishing: What is world’s best practice?
Provedor de dados: 21
Autores: Paull, John.
Open access publishing delivers on the dream of centuries - the free and unfettered access to the written word. However there are shades of openness and the question raised is 'what is world's best practice for open access publishing?'  Four criteria are proposed  to generate a star rating for an open access journal - for ‘openness’ - with a star available for meeting each criterion, to a maximum of four. The open access criteria for scoring star ratings are: (1) There is no barrier to access for the reader; (2) It is free to the author/s; (3) Copyright is retained by the author/s; and (4) The paper can be freely distributed under licence. The Journal of Organic Systems 'ticks all the boxes' to rate as a four-star open access journal.

Organic farming may contribute substantially to future agricultural production worldwide by improving soil quality and pest control, thereby reducing environmental impacts of conventional farming.  We investigated in a comprehensive way soil chemical, as well as below and aboveground biological parameters of two organic and two conventional wheat farming systems that primarily differed in fertilization and weed management strategies. Contrast analyses identified management related differences between "herbicide-free" bioorganic (BIOORG) and biodynamic (BIODYN) systems and conventional systems with (CONFYM) or without manure (CONMIN) and herbicide application within a long-term agricultural experiment (DOK trial, Switzerland). Soil carbon content was...

In France Fruit production is cultivated on 140 thousand hectares, mainly conducted on intensive training system. Very few elements are available on low input training systems while they have to integrate the Global rule under the frame of Ecophyto 2018. In order to evaluate if another system of cultivation will be possible, a project has been developed to highlight the main factors to be integrated in low input training system. A low input multilocal experimental design has thus been investigated on apricot in two main regions of production: Rhone valley and Roussillon. A set of 9 common cultivars with 20 replications each, planted in a complete single-tree randomization design has been established.  As already observed in apple orchard, a larger set of...

Spatial variability of symbiotic N2 fixation in grass-white clover pastures estimated by the 15N isotope dilution method and the natural 15N abundance method
Provedor de dados: 21
Autores: Hansen, Jacob P.; Vinther, Finn P.
Aiming at estimating the spatial variability in N2 fixation, and to evaluate the appropriateness of the 15N isotope dilution (ID) method and the natural 15N abundance (NA) method in reflecting spatial variability under the influence of cattle grazing, the symbiotic N2 fixation in grass-white clover mixture was studied. At the Foulum site, where the ID method was used, differences in the climatic conditions between the two years of investigations caused a considerable difference in plant growth rates and proportion of clover. Consequently, the total N2 fixation in ungrazed reference plots was significantly less in 1998 than in 1997, being 5.9 and 12.5 g N m-2, respectively. In both years there was a wide range in concentration of inorganic N in the soil...

Herbage dry-matter production and forage quality of three legumes and four non-leguminous forbs grown in single-species stands
Provedor de dados: 21
Autores: Elgersma, A.; Søegaard, K.; Jensen, S.K.
Agronomic data on most broad-leaved species of grasslands are scarce. The aim of this study was to obtain novel information on herbage DM yield and forage quality for several forb species, and on species differences and seasonal patterns across harvests and in successive years. Four non-leguminous forbs [salad burnet (Sanguisorba minor), caraway (Carum carvi), chicory (Cichorium intybus) and ribwort plantain (Plantago lanceolata)] and three leguminous forbs [yellow sweet clover (Melilotus officinalis), lucerne (Medicago sativa) and birdsfoot trefoil (Lotus corniculatus)] and a perennial ryegrass–white clover mixture were investigated in a small-plot cutting trial in Denmark during 2009 and 2010. Plots were harvested four times per year. On average, annual...

Sulphate leaching and sulphur balances of an organic crop rotation on three Danish soils
Provedor de dados: 21
Autores: Eriksen, J.; Olesen, J.E.; Askegaard, M.
Sulphate leaching may reduce the long-term possibility of maintaining the sulphur (S) supply of crops in low input farming systems. Sulphate leaching and S balances were investigated in an organic cereal crop rotation with barley (Hordeum vulgare), grass-clover (Lolium perenne/Trifolium repens and pratense), winter wheat (Triticum aestivum) and barley/pea (Pisum sativum) in mixture at three sites during the first 3 years after conversion to organic farming. Sulphate leaching decreased significantly during the 3 years, and the concentration of drainage water was lowered 1.85.5 times in the third year. Similarly, the S-content of the crops decreased significantly over the years, reflecting lower soil S availability. Sulphur application to spring barley at...
