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.

Provedor de dados: 21
Autores: Rover, Oscar José; Anchau, Cleusa Teresinha.
O artigo analisa as estratégias de 03 redes de cooperativas que trabalham com leite no Território Oeste de Santa Catarina, verificando sua aproximação com princípios e práticas agroecológicas. Foram estudadas as redes Aurora, Terra Viva e Ascooper, analisando documentos e realizando entrevistas com suas principais lideranças. A agricultura familiar está na base organizacional das 03 redes e ela adotou a produção de pastagem como a principal forma de alimentação dos animais, o que representa uma inovação coletiva no território, ocorrida de forma difusa, sem liderança de nenhum ator social específico. Além da produção à pasto, a Terra Viva e a Ascooper avançaram com a fitoterapia e a homeopatia na sanidade dos animais, mostrando maior ênfase na construção de...

A Century of Synthetic Fertilizer: 1909-2009
Provedor de dados: 21
Autores: Paull, John.
This year marks a centenary of the synthetic fertilizer industry. German chemists, Fritz Haber and Carl Bosch, in 1909 demonstrated their industrial process for the manufacture of ammonia. The achievement won them accolades including Nobel Prizes. The output of their Haber-Bosch process can be used for either peace or war, agriculture or munitions, and the rapid adoption by Germany of this industrial process is credited with prolonging WW1. Most  of the synthetic nitrogenous fertilizer of the past century, and right up to the present, has been manufactured using the Haber-Bosch process. The use of synthetic fertilizers has led to significant negative environmental outcomes. Rudolf Steiner was an early voice against chemical agriculture. Steiner's...

A colonização do mundo rural e a emergência de novos atores.
Provedor de dados: 21
Autores: Brandenburg, Alfio.
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.

A Comparative Analysis of Organic and Conventional Farming Profitability
Provedor de dados: 21
Autores: Brozova, Ivana.
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....

A comparative study of clinical manifestations, haematological and serological responses after experimental infection with Anaplasma phagocytophilum in two Norwegian sheep breeds
Provedor de dados: 21
Autores: Stuen, Snorre; Grøva, Lise; Granquist, Erik G; Sandstedt, Karin; Olesen, Ingrid; Steinshamn, Håvard.
Background: It has been questioned if the old native Norwegian sheep breed, Old Norse Sheep (also called  Norwegian Feral Sheep), normally distributed on coastal areas where ticks are abundant, is more protected against  tick-borne infections than other Norwegian breeds due to a continuously high selection pressure on pasture. The  aim of the present study was to test this hypothesis in an experimental infection study.  Methods: Five-months-old lambs of two Norwegian sheep breeds, Norwegian White (NW) sheep and Old Norse  (ON) sheep, were experimentally infected with a 16S rRNA genetic variant of Anaplasma phagocytophilum (similar  to GenBank accession number M73220). The experiment was repeated for two subsequent years, 2008 and 2009,  with the use of 16...

Provedor de dados: 21
Autores: Oelofse, Myles; Høgh-Jensen, Henning; de Abreu, L.S.; de Almeira, G.F.; Hui, Q.Y.; de Neergaard, Andreas.
Increased demand for certified organic products has led to  an increase in the number of certified organic farms in developing countries. Knowledge of farmer nutrient management practices on certified organic farms in developing countries is limited. Thus, the aim of this study was to investigate the impact of the adoption of certified organic agriculture on farm nutrient flows and nutrient budgets, and evaluate to which degree organic farms comply with organic principles relating to nutrient   management. The study is based on five case studies of different types of certified organic farming systems in Brazil, Egypt and China. Farm nutrient flows and nutrient budgets for nitrogen, phosphorous and potassium were created for each farm. Four of the five...

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...

Provedor de dados: 21
Autores: Kochakinezhad, Hamed; Peyvast, Gholam-Ali; Kashi, Abdol-Karim; Olfati, Jamal-Ali; Asadi, A.
Tomato (Lycopersicon esculentum Mill.) is one of the most popular and versatile vegetables in the world, and organic production with a high yield and desirable quality is a target of many producers. The effect of four different fertilizers (chemical, municipal solid waste compost, cattle manure, and spent mushroom compost) on four commercial tomato cultivars (Redstone, Flat, Peto Pride and Chief) was assessed in this research. The highest yield was obtained with the Chief cultivar when fertilized with chemical fertilizer and the lowest value was obtained with Peto Pride fertilized with 20 tonnes per hectare (t/ha) of cow manure. The difference between the two classes of fertilizers (organic and chemical) was not very high so that organic fertilizers are...

A comparison of soil and water properties in organic and conventional farming systems in England
Provedor de dados: 21
Autores: Hathaway-Jenkins, L. J.; Sakrabani, R; Pearce, Bruce; Whitmore, A. P; Godwin, R. J.
Organic farming and improvements to agricultural sustainability are often seen as synonymous. However, an extensive European review demonstrated that in practice this is not always true. This study aims to compare the status of soil and water properties between separate fields managed in either an organic or a conventional manner. Soil samples were collected from 16 pairs of farms, throughout England, with both arable and grass fields within each pair on similar soil type. Chemical (nutrients, pesticides, herbicides) and physical (aggregate stability, field capacity, shear strength, soil organic matter, infiltration rates) soil properties were measured in four main soil texture classes in organic and conventional fields. The physical soil properties varied...

Provedor de dados: 21
Autores: Borsatto, Ricardo Serra; Carmo, Maristela Simões do.
Na última década, o Movimento dos Trabalhadores Rurais Sem-Terra (MST), que luta pela reforma agrária no Brasil, vem mudando de forma radical o seu discurso para uma proposta mais coerente com as diretrizes preconizadas pela agroecologia. Neste contexto, o intuito do presente trabalho foi o de compreender, a partir de uma abordagem teórico-histórica, a apropriação do conceito agroecologia como bandeira na luta pela reforma agrária defendida pelo MST. Para tanto, partiu-se de revisões sobre as concepções clássicas relativas ao papel do campesinato nas sociedades contemporâneas e buscou-se realizar "pontes teóricas" com os discursos e as ações praticadas pelo MST em sua história, baseando-se em análise documental. Por fim, este artigo conclui que a defesa da...

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...

A field trial on the effects of pure sodium propionate and a combination with herbal extracts on short term development of subclinical ketosis
Provedor de dados: 21
Autores: Dorn, Katharina; Leiber, Florian; Sundrum, Albert; Holinger, Mirjam; Mayer, Philipp; Walkenhorst, Michael.
While glucogenic substances in ketosis prevention are commonly used, there is a lack of clinical studies about the effectiveness of ketosis therapy in particular by means of sodium propionate and herbal extracts. Fresh cows between 5 and 50 days in milk of 25 Swiss and German dairy farms were tested weekly for ketone bodies in blood. From 283 cows, 121 (42.8%) exceeded the threshold of 1.0 mmol/l blood-β-hydroxybutyrate (BBHB). Thereof 84 cows were randomly assigned to three treatments on each farm. Treatment SP-H was composed of sodium propionate (120 g per application) and an aqueous extract of seven herbs (13.5 g drug equivalent per application), treatment SP comprised pure sodium propionate (120 g per application) and treatment PL was a placebo.

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...

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...

A Gardener's Influence on Urban Soil Quality
Provedor de dados: 21
Autores: Tresch, Simon; Moretti, Marco; Le Bayon, Renée-Claire; Mäder, Paul; Zanetta, Andrea; Frey, David; Fliessbach, Andreas.
Gardens are hot spots for urban biodiversity and provide habitats for many plant and animal species, both above- and below-ground. Furthermore, gardens provide a wide range of ecosystem services, including carbon (C) storage and nutrient cycling. Although the soil is the foundation of sustainable gardens providing those ecosystem services, very little is known about the consequences of garden management on soil quality. Here we present a comprehensive assessment of urban garden soil quality, including biotic and abiotic site characteristics combined with land-use history and garden management information in a multivariate evaluation. A set of 44 soil quality indicators was measured at 170 sites of 85 gardens in the city of Zurich, Switzerland, comprising...

A general extrudate bulk density model for both twin-screw and single-screw extruder extrusion cooking processes
Provedor de dados: 21
Autores: Cheng, Hongyuan; Friis, Alan; Høeg Hansen, Jonas; Tolderlund Rasmussen, Hanne.
Effects of extrusion parameters and raw materials on extrudate expansion are respectively investigated in a twin-screw extruder and a single-screw extruder extrusion cooking experiments for fish feed, wheat, and oat &amp; wheat mixture processing. A new phenomenological model is proposed to correlated extrudate bulk density, extrusion parameters and raw material changes based on the experimental results. The average absolute deviation (AAD) of the correlation is 2.2% for fish feed extrusion in the twin-screw extrusion process. For the single-screw extrusion process, the correlation AAD is respectively 3.03%, 5.14% for wheat and oat &amp; wheat mixture extrusion; and the correlation AAD is 6.6% for raw material change effects.

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...

A guide to organic grassland
Provedor de dados: 21
Autores: Philipps, Lois.
Organic farming systems in the UK are traditionally based on ley/arable crop rotations. Up to 70% of the farmed area comprises of mixed grass and legume leys. These leys offer a powerful mechanism for supplying nitrogen through their potential to harvest biologically fixed nitrogen to support both animal production and a subsequent phase of arable cropping.  This bulletin answers some of the common questions about organic grassland management.

A herbal feed additive shows potential to improve metabolic situation in early lactating dairy cows
Provedor de dados: 21
Autores: Walkenhorst, M.; Ivemeyer, S.; Schaette, R.; Mayer, P.; Arndt, G.
The gap between performance and feed intake in early lactating dairy cows often leads to metabolic imbalance which is connected to udder inflammation (UI).  A study with 72 dairy cows calving from November 2010 to March 2011 on 10 Swiss and German farms was conducted to test the effect of a herbal feed additive (HFA) containing mainly Urtica dioica L. (herba), Silybum marianum (L.) Gaert. (fructus), Artemisia absinthium L. (herba) and Achillea millefolium L. (herba).  Cows were stratified (farm and milk yield) randomised divided into three groups. From 14 days prior predicted calving to the end of the following lactation cows received daily 100 g pellets containing A: 100% HFA, B: 50% HFA and 50% alfalfa and C: 100% alfalfa (placebo).

Autores: Hotzel, Maria José; Teixeira, Dayane Lemos; Machado Filho, Luiz Carlos Pinheiro.
Pequenas propriedades leiteiras no sul do Brasil freqüentemente oferecem água para as vacas em um único bebedouro na sala de ordenha, o que pode limitar o consumo de água, com conseqüências negativas na produção e bem-estar animal. Para testar a influencia da restrição de água e dominância social na ingestão de água e no comportamento, 14 animais (novilhas, vacas em lactação e secas) foram submetidos a dois tratamentos num delineamento do tipo cross-over: acesso à água permanente (APer) ou restrito a uma vez ao dia (ARest) durante 17 dias em cada fase. A ingestão de água foi medida diariamente através de um relógio medidor de vazão acoplado à saída de água e o comportamento foi observado entre os dias 13 e 17 de cada fase, por observação visual direta, das...

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...

A growing number of people live in cities. Urban food systems and their impacts on ecosystems and socio-economic conditions are becoming increasingly important. To address the challenge of making urban food systems more sustainable, a rising number of assessments of urban food systems have been published. Some used large quantitative datasets while others were descriptive in nature and/or do not address the whole thematic spectrum of sustainability. In this study, an indicator set was developed, which uses widely available data to address all dimensions of sustainability. The indicators focus on policies and measures of public administration and local politics and are based on the guidelines for Sustainability Assessment of Food and Agriculture Systems...

Autores: Attanasio, Cláudia Mira; Gandolfi, Sergius; Zakia, Maria José B.; Veniziani Junior, José Carlos Toledo; Lima, Walter de Paula.
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...

A localised development of organic farming as a response to the problem of water quality: a new challenge
Provedor de dados: 21
Autores: Vincent, A; Fleury, Philippe.
Initiatives aiming at developing organic farming (OF) to meet water quality stakes are increasing. This article is a comparative study of four such projects. It is based on semi-structured interviews. Two logics for public action are implemented to foster the development of OF in areas facing water quality problems. The first one aims at concentrating actions in water sensitive areas. The main tool that is then mobilized is the use of localized agri-environmental measures supporting conversion to organic farming. The second logic aims at implementing actions for organic development at a geographical scale considered as relevant for developing OF and differing from water sensitive areas. The main actions that are then activated are coordination,...

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...

O fortalecimento de organizações sociais que possibilitaram fazer da produção de leite uma atividade destinada ao mercado provocou profundas mudanças na divisão sexual do trabalho. A análise sociológica das trocas intradomiciliares nos estabelecimentos rurais familiares mostra que tradições culturais, diferenças de poder entre os gêneros e contextos sociais que ampliam diferenças de acesso aos mercados entre homens e mulheres são as bases sociais e culturais de uma hierarquia estruturada segundo sexo e geração, no qual as mulheres, especialmente as mais jovens, ocupam posições de grande desvantagem.

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...

A model simulation analyses of nitrate leaching – does soil organic matter pool structure or catch crop growth parameters matter most?
Provedor de dados: 21
Autores: Pedersen, Anders; Petersen, Bjørn Molt; Eriksen, Jørgen; Hansen, Søren; Jensen, Lars Stoumann.
Modelling of soil organic matter (SOM) turnover has often been developed in order to or to predict crop fertilser demand or to analyse environmental impact of different agriculture management practices. Mechanistic simulation models can be used to predict the mineralization of nitrogen (N) in added organic matter, e.g. from animal manure or incorporated crop residues, and the timing of N availability to the succeeding crops. In this way, mechanistic models may be used to avoid excessive fertilisation and hence to minimise nitrate leaching. The objective of this work was therefore to analyse the consequences of applying different SOM and crop modules (differing in pool structure or parameterisation) in the soil-plant-atmosphere model Daisy on the simulated...

This paper presents a new approach to evaluate the cost effectiveness of agri-environmental policies at sector level. Policy uptake, cumulative environmental effects and public expenditure are identified as the main determinants of cost-effectiveness. On the basis of the sector-consistent, comparative-static, farm group model FARMIS, the determinants of policy cost-effectiveness at sector level are addressed. Firstly, intensity levels for the FARMIS activities are defined in order to model uptake of agri-environmental policies with FARMIS, secondly, life-cycle assessment data is attached to these intensity levels to determine environmental effects of the policies and thirdly, public expenditure is calculated under consideration of transaction costs.

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...

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. However, in the phylogenies gained from...

A new genus, Desertispora, and a new species, Diversispora sabulosa, in the family Diversisporaceae (order Diversisporales, subphylum Glomeromycotina)
Provedor de dados: 21
Autores: Symanczik, Sarah; Al-Yahya'ei, Mohamed N.; Kozłowska, Anna; Ryszka, Przemysław; Błaszkowski, Janusz.
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...

A new integrative assessment indicator for damage caused by major pests and diseases in the vineyard
Provedor de dados: 21
Autores: Delbac, L; Constant, N; Laveau, E; Thiéry, D; Smits, N; Roudet, J; Mérot, A; Wéry, J; Fermaud, M.
An original and integrative evaluation indicator has been developed to quantify the cumulated damage from major pests and diseases affecting grape bunches: downy mildew, powdery mildew, gray mould and tortricid moths. It made it possible to estimate the associated crop losses and to relate them to the plant protection strategy in different modes of production (organic farming, in-transition, conventional). Thus, overall plant losses were higher in 2012 than in 2011. The in-transition growers’ strategy, with reduced copper doses but increased numbers of sprays, led to a 20% increase in average severity on bunches (essentially due to Downy mildew). The more pragmatic approach of experienced organic growers and conventional ones (higher doses and fewer...

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...

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.

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...

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.

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....

At the height of his powers, Rudolf Steiner presented a two-week conference at Oxford. The ‘Oxford Holiday Conference’ was titled ‘Spiritual Values in Education &amp; Social Life’ (Mackenzie, 1922b), and it was this 1922 conference that laid the foundations for establishing Waldorf education in Britain and from there the rest of the Anglo world. The original Waldorf School had been established in 1919 by Rudolf Steiner at the invitation of a German industrialist, Emil Molt, in Stuttgart, Germany. Steiner states that in the Waldorf School he sought "to apply the educational principles arising out of Anthroposophy”. The Stuttgart school began with 150 students and this had grown to 700 by the time of the Oxford Conference. The Oxford Conference ran from...

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.

A project-based system for including farmers in the EU ETS
Provedor de dados: 21
Autores: Svendsen, Gert Tinggaard; Brandt, Urs Steiner.
Farmers in the EU do not trade greenhouse gases under the  Kyoto agreement. This is an empirical puzzle because agriculture is a significant contributor of greenhouse gases (GHG) in the EU and may harvest private net gains from trade. Furthermore, the US has strongly advocated land-use practices as ‘the missing link’ in past climate negotiations. We argue that farmers have relatively low marginal reduction costs and that consequences in terms of the effect on permit price and technology are overall positive in the EU Emission Trading System (ETS). Thus, we propose a project-based system for including the farming practices in the EU ETS that reduces the uncertainty from measuring emission reduction in this sector. The system encourages GHG reduction either...

A especificidade do processo de apropriação privada de terras públicas no Brasil, após 1850, é o ponto de origem dos problemas ambientais atuais no espaço rural, isso porque foi desse período em diante que a ausência de limites ambientais se tornou a regra principal da aliança entre a concentração fundiária e o progresso técnico aplicado à agricultura, comprometendo dramaticamente outras formas de acesso, bem como o uso produtivo ou não produtivo das terras e seus recursos naturais. O estudo de caso realizado na região sudoeste do Paraná, no Sul do Brasil, no entanto, demonstra que, apesar de uma estrutura agrária mais democrática, a regra de ausência de limites ambientais também é reiterada. Naquela região, o impulso básico à degradação ambiental deve-se...

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...

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...

Já no primeiro mandato do presidente Fernando Henrique Cardoso, a política agrária sofreu reorientações significativas, que marcariam seu segundo mandato, a partir da nomeação de Raul Jungmann como ministro do Desenvolvimento Agrário. A reforma agrária finalmente encontrou o seu sujeito, a agricultura familiar, e o Estado encontrou a sua missão agrária como gestor do território. Foram assim estabelecidas as bases concretas para o exercício da função social da propriedade, recuperando o Estado, na prática, o domínio eminente do território do país. Importante providência nesse sentido foi a anulação dos títulos irregulares de propriedade de sessenta milhões de hectares de terra. O governo firmou a prerrogativa do Estado de "rotinizar" a redistribuição da...

Autores: Watson, C.A.; Bengtsson, H.; Ebbesvik, M.; Loes, A-K.; Myrbeck, A.; Salomon, E.; Schroder, J.; Stockdale, E.A.
On organic farms, where the importation of materials to build/maintain soil fertility is restricted, it is important that a balance between inputs and outputs of nutrients is achieved to ensure both short-term productivity and long-term sustainability. This paper considers different approaches to nutrient budgeting on organic farms and evaluates the sources of bias in the measurements and/or estimates of the nutrient inputs and outputs. The paper collates 88 nutrient budgets compiled at the farm scale in 9 temperate countries. All the nitrogen (N) budgets showed an N surplus (average 83.2 kg N ha-1 year-1). The efficiency of N use, defined as outputs/inputs, was highest (0.9) and lowest (0.2) in arable and beef systems respectively. The phosphorus (P) and...

A row cropping system with cover crops for balancing weed and soil fertility management in organic cereal production
Provedor de dados: 21
Autores: Phan, Hong TT; Thorup-Kristensen, Kristian.
This manuscript shows the result from testing the new row cropping system for its ability to produce a balanced combination of inter-row hoeing and undersown cover crop in order to obtain a sufficient N supply and an effective weed control as well as to identify optimal sowing time for high biomass production and cover crop species suited for late undersowing. The new system produced a sufficient N supply and an acceptable weed control effect, leading to an improvement in the subsequent crop yield. Yield in this system is potentially improved further because some managements are suggested to increase its weed control effect, especially for the perennial creeping thistle cirsium arvense.

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...

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...

A Simulation Model of Combined Biogas, Bioethanol and Protein Fodder Co-Production in Organic Farming
Provedor de dados: 21
Autores: Oleskowicz-Popiel, Piotr; Thomsen, Mette Hedegaard; Thomsen, Anne Belinda; Schmidt, Jens Ejbye.
In order to evaluate new strategies for the production of  renewable energy within sustainable organic agriculture, a process-simulation model for a 100 ha organic farm was developed. Data used for the model was obtained from laboratory trials, literature data, consultancy with experts, and results from the BioConcens project (http://www.bioconcens.elr.dk). Different design approaches were evaluated in order to establish the most suitable configuration. Rye grains, clover grass silage, maize silage, whey and cattle manure were selected as raw materials for co-production of fuels, feed and fertilizer at the organic farm, based on the fact that crops grown in organic agriculture act as key carbon sources whereas manure and whey were applied primarily as the...

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...

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.

A weed suppressive index for spring barley (Hordeum vulgare L.) varieties
Provedor de dados: 21
Autores: Hansen, Preben Klarskov; Willas, Jakob; Kristensen, Kristian.
A screening programme for crop variety competitiveness would ideally be based on only a few, non-destructive measurements of key growth traits. In this study we measured the weed suppressive ability of 79 varieties of spring barley in two ways: 1) directly, by weed coverage assessments under weedy conditions at three Danish locations in 2002-2004, and 2) indirectly, by non-destructive measurements of varietal growth traits under weed-free conditions in 17 other experiments in Denmark in 2001-2003. Based on just four varietal growth traits (reflectance, leaf area index, leaf angle and culm length), we successfully developed a method for indexing the weed suppressive ability of spring barley varieties. The suppressive index ranged from 12% in ‘Lux’ and 55%...

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.

Abflammen von Säzwiebeln im Nachauflauf
Provedor de dados: 21
Autores: Laber, H.; Baumgarten, B.; Stützel, H.; Wonneberger, C.
Einleitung:  Für den ökologischen Anbau von Säzwiebeln ist das Abflammen ein wesentliches Glied in der Kette der Maßnahmen zur Unkrautregulation, ohne das ein großflächiger Anbau nicht denkbar wäre. Anders als bei der Möhre und anderen Arten, bei denen das Abflammen vor Auflauf der Kultur durchzuführen ist, sind bei Zwiebeln auch Behandlungen im Nachauflauf möglich. In der Praxis taucht aber immer wieder die Frage auf, bis zu welchem Entwicklungsstadium das Abflammen erfolgen kann, ohne die Pflanzen nachhaltig zu schädigen.    Im Rahmen einer Diplomarbeit (LABER 1990) wurden die Auswirkungen unterschiedlicher Abflammtermine bei Säzwiebeln näher untersucht.    Fazit:  - Abflammbehandlungen im Nachauflauf der Zwiebeln reduzieren den Aufwand beim ersten...

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...

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...

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...

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...

Action research program on the innovations of the Organic economy
Provedor de dados: 21
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.

Actividad insecticida del aceite esencial de Lippia alba (Mill.) N. E. Brown sobre Tribolium castaneum Herbst. en granos de trigo (Triticum aestivum L.)
Provedor de dados: 21
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...

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),...

Adding value to vegetable waste: Oil press cakes as substrates for microbial decalactone production
Provedor de dados: 21
Autores: Laufenberg, Günther; Rosato, Pietro; Kunz, Benno.
In this study several oil press cakes were investigated as exclusive substrates for different moulds and yeasts for the production of flavor-active decalactones via solidstate fermentation (SSF). Experiments are focused on pre-treatment methods for olive cake to remove antimicrobial phenolic substances contained in the oil cake disturbing or even inhibiting microbial growth. Choosing Ceratocystis moniliformis as the reference microorganism best results were obtained by a combination of hot water flushes and enzymatic treatment of the cake. Fermentation with sunflower, olive and linseed cake did not lead to lactone formation in detectable amounts although all of these substrates provided good microbial growth. On castor cake, however, five microorganisms...

Autores: Adler, Steffen.A.; Randby, Åshild.T.
Effekten av tre ulike konserveringsmetoder for bygg på fôropptak og melkekvalitet i økologisk landbruk ble testet i et fôringsforsøk med cross over design med tre perioder á en uke. Kyrne ble tildelt 6,0 kg TS (førstekalvskyr 5,0 kg TS) av enten tørket bygg (Arve), valset bygg ensilert med melasse, eller valset bygg ensilert med syrer. I tillegg til bygg ble kyrne tildelt grassurfôr ad libitum og en mineral/vitamin-blanding. Forsøket ble gjennomført i Bodø i mars 2004.  Alle de tre metodene konserverte bygget godt. Konserveringsmetoden hadde ingen innvirkning på det totale fôropptaket. Kyrne var i sen laktasjon og melkeproduksjonen var lav, men det var ingen forskjell i ytelse mellom konserveringsmetodene for bygg. Innholdet av råprotein var lavt i...

Adoption and Abandonment of Organic Farming: An Emperical Investigation of the Irish Drystock Sector
Provedor de dados: 21
Autores: Läpple, Doris.
There is a considerable literature about the adoption of organic farming. However,  possible abandonment of organic farming has received scant attention.  Thus, relatively little is known about the exit decisions of farmers. In addition,  most studies are based on a static framework where it is not possible to account  for changes in farmer decisions over time. This article attempts to fill this gap in  the literature by investigating the determinants that affect both adoption and  abandonment of organic drystock farming over time. The use of duration analysis  allows for the consideration of cross-sectional and time-varying factors over  the study period from 1981 to 2008. Using this dynamic econometric framework  revealed a significant time effect on...

Adoption of organic farming: Are there differences between early and late adoption?
Provedor de dados: 21
Autores: Läpple, D.; Van Rensburg, T.
Based on the fact that not all farmers adopt a technology at the same time, it is argued in this paper that the distinction between groups is important because early, medium and late adopters respond differently to economic and non-economic factors when they consider whether to take up organic farming or not. The individual effects on adoption between the groups are identified by the use of multinomial logit analysis. The results provide evidence that there are significant differences in the characteristics between the adopter groups. The findings also reveal that the factors that affect adoption play a different role for early, medium and late adopters, particularly with regard to farming intensity, age, information gathering as well as attitudes of the...

Autores: Hossain, Shaikh Tanveer; Sugimoto, Hideki; Ueno, Hideto; Huque, Sheikh Muhammad Rafiul.
Bangladesh now needs to thank its soil health, environment and human health for the country being almost self-sufficient in rice production. The present study has been undertaken to gain knowledge of the level of awareness by farmers and consumers regarding the status of organic rice, and knowledge of demand and marketing opportunities and limitations for organic rice in the country. The present study has highlighted the overall organic rice situation in Bangladesh, which is not yet well documented. The results also demonstrate that farmers and consumers are aware of the hazards of chemical compounds but have little knowledge about organic rice. The present study may open a new window for organic rice research and marketing (both local and export) for all...

Advances in the knowledge of quinoa pests
Provedor de dados: 21
Autores: Rasmussen, Claus; Lagnaoui, Aziz; Esbjerg, Peter.
A wide range of quinoa pests are known throughout the world. The most serious of the Andean pests are Eurysacca melanocampta (Meyrick) and E. quinoae Povolny´ (Lepidoptera: Gelechiidae), found mainly in Peru and Bolivia, which cause considerable yield losses. Insects found elsewhere in the world are polyphagous pests constituting a wide range of potential pests if quinoa is implemented as a crop in those regions. Other major pests include a group of cutworms (Noctuidae). Apart from insects birds cause a major loss through foraging, damaging cotyledonous plants and inflorescences, with yield losses of up to 60%. Cultural practices and host plant resistances will be important components of integrated pest management (IPM). Biological control of the main...

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...

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...

Afgræsningsmarkers eftervirkning
Provedor de dados: 21
Autores: Eriksen, J.
I nitratfølsomme vandindvindingsområder med landbrugsproduktion tilrådes af forsigtighedshensyn en grænseværdi på 50 mg nitrat pr. liter i nedsivningsvandet. Til trods for et lavere udvaskningspotentiale i økologisk end i konventionelt jordbrug, så har økologisk jordbrug ikke altid nitratkoncentrationer under grænseværdien – det gælder især på kvægbrugene. Årsagen er, at intensive afgræsningssystemer forøger tabsrisikoen pga. at drøvtyggere udskiller 75-95% af deres N-indtag i gødningen, og hovedparten af dette bliver afsat i marken under afgræsning. På den måde sker der en betydelig opbygning af N i afgræsningsmarker, og ved ompløjning frigives derfor hyppigt N i et omfang, som den efterfølgende afgrøde ikke er i stand til at udnytte med nitratudvaskning...

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...

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.

Agrarpolitische Bewertung der Umwelteffekte des ökologische Landbaus
Provedor de dados: 21
Autores: Dabbert, S.; Stolze, M.; Häring, A. M.; Piorr, A.
Der ökologische Landbau war ursprünglich ein Teilbereich der Landwirtschaft, der sich weitgehend unabhängig von staatlichen Einflüssen entwickelt hat. Seit Ende der 80er Jahre des vorigen Jahrhunderts nahm der direkte staatliche Einfluss zu, und heute gibt es kein EU-Land mehr, indem der ökologische Landbau nicht direkt durch staatliche agrarpolitische Maßnahmen gefördert wird.   Die wichtigste Begründung, die für die politische Förderung des ökologischen Landbaus genannt wird, sind seine positiven Umwelteffekte. Da es sich bei Umweltgütern um öffentliche Güter handelt, werden diese von den Wirtschaftssubjekten in zu geringem Umfang bereitgestellt. Um eine gesamtwirtschaftlich optimale Lösung zu erreichen, sind daher staatliche Eingriffe gerechtfertigt....

Agrarumweltprogramm mit Ökobilanz im Allgäu zielorientiert gestalten
Provedor de dados: 21
Autores: Haas, Guido.
Mit einer Ökobilanz von 18 Grünlandbetrieben in den drei relevanten Förderprogrammen des Bayerischen Kulturlandschaftsprogramms „Intensiv” - quasi ohne Auflagen, „Extensiviert” - Verbot mineralischer Stickstoffdüngung - und „Ökologischer Landbau” wurden ökologische Schwachstellen des Agrarumweltprogramms festgestellt und wirksame Handlungsansätze abgeleitet. Die Förderung von Intensiv-Betrieben (etwa 43 % aller Betriebe) erfolgt ohne nachweisliche Minderung der Umweltbelastung. Durch Förderung des Verzichts auf mineralische N-Dünger im Programmteil „Extensiviert” (etwa 46 % aller Betriebe) ist eine Entlastung des Naturhaushaltes in den Bereichen Energieverbrauch, Klima und Grundwasser festzustellen. In den im Allgäu zentralen Umweltbereichen...

Agricultores (e pescadores) da Amazônia central brasileira: racionalidades e trajetória recente dos sistemas agrícolas em duas unidades de conservação do Médio Solimões, Amazonas.
Provedor de dados: 21
Autores: Pereira, Kayo Julio Cesar.
O presente artigo apresenta uma análise do papel da agricultura nos sistemas de produção das Reservas Amanã e Mamirauá, descrevendo sua trajetória recente em nove comunidades, e identificando as principais identidades produtivas. Predomina em todas as comunidades um sistema de produção complexo, formado por agricultura, pesca, caça e extrativismo, com a agricultura ou a pesca assumindo função protagônica, de acordo com a estratégia de geração de renda de cada família. Os sistemas agrícolas vêm passando por intenso processo de transformação, diretamente relacionado à intensificação do contato das comunidades com a vida citadina, com a implantação de políticas de conservação e manejo dos recursos naturais e com o incremento da importância dos produtos...

Agricultura apoiada pela comunidade: poderia a experiência dos agricultores americanos ser útil para os agricultores urbanos brasileiros?
Provedor de dados: 21
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....

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...

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.

Agricultura familiar e agroecologia: perfil da produção de base agroecológica do município de Pelotas/RS.
Provedor de dados: 21
Autores: Finatto, Roberto Antônio; Salamoni, Giancarla.
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,...

Autores: Paqualotto, Nayara; Godoy, Wilson Itamar; Verona, Luiz Augusto Ferreira.
O objetivo do artigo é apresentar algumas reflexões sobre os padrões sucessórios da agricultura familiar em agroecossistemas hortícolas de base ecológica no sudoeste paranaense. Os dados apresentados apontam que a mão de obra familiar nestas unidades de produção tem como tendência a sua escassez, visto que grande parte dos envolvidos nas atividades tem idade superior a trinta anos. Dos seis agroecossistemas pesquisados, os jovens integram apenas duas das famílias agricultoras, porém os mesmos não participam das atividades dos agroecossistemas. Este cenário proporciona uma reflexão a respeito do futuro da agricultura familiar e da Agroecologia na região, evidenciando assim a necessidade de ações para o seu fortalecimento, sendo que este é um dos caminhos...

Autores: Anjos, Flávio Sacco dos; Godoy, Wilson Itamar; Caldas, Nádia Velleda; Gomes, Mário Conill.
A aparição do Programa Nacional de Fortalecimento da Agricultura Familiar (PRONAF) marca um momento singular na trajetória do processo de intervenção estatal na agricultura e no mundo rural do Brasil. Apesar de avanços no aperfeiçoamento e ampliação do universo de cobertura, o programa permanece ancorado numa ambigüidade básica tanto em termos do público-alvo a ser beneficiado quanto aos objetivos essenciais que persegue, onde, na retórica oficial, mesclam-se orientações tipicamente produtivistas com compromissos mais amplos, como a geração de empregos, a inclusão social e o desenvolvimento territorial.

Autores: Ribeiro, Eduardo Magalhães; Galizoni, Flávia Maria; Silvestre, Luiz Henrique; Calixto, Juliana Sena; Assis, Thiago de Paula; Ayres, Eduardo Barbosa.
Os regimes agrários peculiares e os baixos níveis relativos dos indicadores sócio-econômicos fizeram com que a região do alto Jequitinhonha, nordeste de Minas Gerais, fosse considerada uma das mais complexas do Brasil. Por isso, vários governos orientaram para lá programas de desenvolvimento rural. Mas esses esforços não produziram bons resultados. Este artigo analisa as relações entre programas públicos e agricultura familiar, fazendo um balanço dos métodos e resultados das últimas três décadas. Conclui pela necessidade de incorporar as especificidades de história, ambientes e sociedade aos programas, que deveriam partir das experiências das organizações da região e se ajustar às ações e à cultura desses agricultores.

Nas últimas décadas, assistimos à revitalização do debate em torno da agricultura familiar pela incorporação das discussões sobre as múltiplas funções da agricultura num rural que não pode mais ser visto como domínio exclusivo da atividade agrícola e dos agricultores. No contexto brasileiro, acreditamos que essa discussão deva ser permeada pela análise de como processos diferenciados de distribuição fundiária e desenvolvimento econômico e o tipo de agricultura resultante geram ruralidades específicas com características como, no caso da agricultura familiar, a manutenção de práticas sociais e de trabalho marcadas pelas relações de parentesco e vizinhança presentes numa sociedade de interconhecimento. Partindo desse princípio, este trabalho analisa a...

Autores: Azevedo, Elaine de; Schmidt, Wilson; Karam, Karen Folador.
A Agricultura Familiar Orgânica, ao se apresentar como um sistema produtivo que objetiva a auto-sustentação da propriedade agrícola, a oferta de alimentos saudáveis e a preservação da saúde ambiental e social, questiona as repercussões negativas do sistema moderno de produção de alimentos e se aproxima da noção de qualidade de vida. Para ilustrar melhor a articulação entre qualidade de vida e Agricultura Familiar Orgânica, buscou-se conhecer as repercussões da adoção de um sistema de produção orgânico sobre a qualidade de vida de agricultores familiares da Associação de Agricultores da Encostas de Serra Geral (AGRECO), em Santa Rosa de Lima, SC. O estudo de campo apresentado nesse artigo ajudou a elucidar a complexidade do conceito de qualidade de vida no...

Agricultural land management, carbon reductions and  climate policy for agriculture
Provedor de dados: 21
Autores: Müller, Adrian.
Agriculture contributes to climate change and at the same time has a huge climate change mitigation potential – this lies mainly in increased soil carbon sequestration. This article discusses the mitigation potential of soil carbon sequestration, the underlying processes and main challenges for its utilization. There are difficulties of reliable quantification, aspects of leakage and system boundaries. Utilization of this mitigation potential is currently mainly via offset mechanisms. Due to the named challenges, offset mechanisms are not adequate for this and more aggregate approaches should be employed.

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...

Agriculture biologique et verrouillage des systèmes de connaissances: Conventionalisation des filières agroalimentaire bio
Provedor de dados: 21
Autores: STASSART, P.M.; JAMAR, D.
La question de la co-existence entre deux systèmes bio, l’un porté par les acteurs historiques, l’autre par les nouveaux acteurs agroindustriels, selon un modèle de bifurcation, est traitée à travers l’hypothèse de conventionalisation. Nous utilisons le cas du système Blanc Bleu Belge et de l’élevage bovin bio belge pour montrer que le problème de la co-existence de ces deux systèmes est à la fois une question empirique et une question théorique. Notre argument est que le concept de « référentiel » (au sens de Jobert et Muller, 1987) est non seulement supérieur d’un point de vue théorique mais qu’il ouvre d’intéressantes perspectives pratiques et ceci pour deux raisons. D’abord parce qu’il permet de comprendre la question et l’enjeu de la co-existence de...

Agrochemical-free, direct-sowing culture of a paddy with non-woven fabric mulch - Timing of puddling and leveling and basal fertilizer application
Provedor de dados: 21
Autores: Hossain, Shaikh Tanveer; Sugimoto, Hideki; Yamashita, Jun; Alcaraz, Joel M.
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...

No artigo é discutido um enfoque científico que pode contribuir para a superação das contradições causadas pelo positivismo e pelo pós-modernismo em relação ao caráter emancipatório da Agroecologia. A partir de uma revisão da bibliografia especializada conclui-se que o conceito de complexidade, considerando-se as suas consequências ontológicas, epistemológicas e sobre o conceito de desenvolvimento sustentável, pode desempenhar um papel fundamental para a superação de tais contradições. Conclui-se também que há, ainda, um imenso trabalho de ordem conceitual, teórica e metodológica a ser realizado para que as atividades científicas desenvolvidas no âmbito da Agroecologia possam se tornar mais coerentes com o caráter emancipatório deste campo.

O que acontece quando consumidores e produtores agroecológicos adotam uma prática econômica alternativa ao consumo convencional? O presente artigo analisa e qualifica as comunidades aprendentes existentes no âmbito desse tipo de prática econômica. O estudo de caso do grupo de consumo coletivo de produtos agroecológicos Trocas Verdes, situado em Campinas (SP), no contexto da agricultura familiar no Brasil, mostrou que as trocas econômicas são também trocas de saberes. Além disso, tais trocas constituem uma práxis em educação ambiental. As três dimensões da sustentabilidade - econômica, social e ambiental - são as categorias de análise utilizadas para determinar o potencial pedagógico existente na articulação de uma prática de consumo coletivo.

A partir de análise da legislação brasileira vinculada ao BEA e de entrevistas realizadas com pesquisadores, legisladores e técnicos do MAPA, buscamos retraçar o ambiente técnico/jurídico que alicerça o BEA no Brasil. As entrevistas foram orientadas por um questionário aberto, realizadas no primeiro semestre de 2011. Consideramos que o BEA possa tornar se um conceito que alberga princípios agroecológicos, recomendáveis na implantação de sistemas de criação e manejos animais, que expressa valores éticos, ecológicos e economicamente justos. Os dados levantados sinalizam para a necessidade de uma maior discussão sobre o tema que ainda se mostra bastante incipiente no Brasil, em especial junto a consumidores. É fundamental para o avanço de BEA no Brasil, as...

Nos últimos anos tanto no Brasil, como na França o tema da agroecologia tem ganhado forte visibilidade na sociedade e ocupado espaços importantes em programas e ações de desenvolvimento rural, bem como, no mundo da pesquisa científica, ensino e no movimento social. Diante desse fato, o objetivo do nosso artigo é o de apresentar os primeiros resultados do projeto Capes-Cofecub1. Primeiramente, analisaremos numa perspectiva cruzada – da sociologia e das ciências agrárias -, a evolução e a dinâmica da agroecologia, indicando as principais ações em curso tendo em conta o processo de institucionalização e estruturação crescente da agroecologia no Brasil e na França. Em seguida, proporemos uma reflexão em torno da agroecologia e ética.

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.

Agroecosystem resilience and farmers’ perceptions of climate change impacts on cocoa farms in Alto Beni, Bolivia
Provedor de dados: 21
Autores: Jacobi, Johanna; Schneider, Monika; Bottazzi, Patrick; Pillco, Maria; Calizaya, Patricia; Rist, Stephan.
Cocoa-based small-scale agriculture is the most important source of income for most farming families in the region of Alto Beni in the sub-humid foothills of the Andes. Cocoa is grown in cultivation systems of varying ecological complexity. The plantations are highly susceptible to climate change impacts. Local cocoa producers mention heat waves, droughts, floods and plant diseases as the main impacts affecting plants and working conditions, and they associate these impacts with global climate change. From a sustainable regional development point of view, cocoa farms need to become more resilient in order to cope with the climate change related effects that are putting cocoa-based livelihoods at risk. This study assesses agroecosystem resilience under...

Agro-environmental evaluation of vineyard management using organic farming and integrated plant production systems
Provedor de dados: 21
Autores: FORGET, D.; LACOMBE, J.; DURAND, A.
Organic farming is often considered to be the most environmentally-friendly crop management system, even if integrated production also aims at decreasing the impact of agriculture on the natural environment. In order to establish references for the agro-environmental evaluation of these two production systems in relation to grape growing, INRA carried out an initial study from 2001 to 2004 at the plot scale. This study focused on two grape varieties (Merlot N and Cabernet Sauvignon) in its Couhins vineyard (Graves cru classé), located on two organically-farmed plots and two plots using integrated production, a system based on the implementation of decision rules aimed at limiting the number of pest control treatments. Production means only differed in...

Agroforestry systems can mitigate the severity of cocoa swollen shoot virus disease

Autores: Andres, Christian; Blaser, Wilma J.; Dzahini-Obiatey, Henry K.; Ameyaw, George A.; Domfeh, Owusu K.; Awiagah, Moses A.; Gattinger, Andreas; Schneider, Monika; Offei, Samuel K.; Six, Johan.
Currently, the only effective treatment for cocoa (Theobroma cacao L.) infected with the cocoa swollen shoot virus disease (CSSVD) is to cut and replant infected trees. Hence, the development of preventive control measures and strategies to mitigate the severity of the disease are of utmost importance. While past research has mainly focused on resistance breeding, mild strain cross protection and vector control, diversification measures such as agroforestry have received relatively less attention, despite their potential to mitigate CSSVD severity.  Therefore, we studied the effects of shade on CSSVD symptom severity, capsid damage and cocoa yield along a gradient of increasing shade tree abundance in smallholder cocoa farms in Ghana. Furthermore, we...

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...

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. The  varieties evaluated incline...

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.

Kvælstof er et værdifuldt næringsstof for opnåelse af et højt frøudbytte, men også i relation til justering af væksten i udlægsmarken. Desværre har mange frøavlere begrænset adgang til kvælstof – dels på grund af en kvælstofnorm, som er fastsat under den økonomisk optimale værdi og dels på grund af begrænset adgang til husdyrgødning på økologiske planteavlsbedrifter. I Forskningsprogram frøavl arbejdes med udvikling af en behovsbestemt gødningsstrategi for at opnå en bedre udnyttelse af den til rådighed værende kvælstofmængde. Imidlertid tyder igangværende forsøg på, at kvælstof findes i ’alternative kilder’ såsom frøgræshalm og grøngødningsafgrøder, men kan de udnyttes i frøavlen?

Autores: Hyvönen, Terho; Jalli, Heikki.
The present study aimed at assessing the invasion of alien weed species in Finland based on a review of their occurrence in the Finnish weed flora. The evaluation was conducted for the three phases of the invasion process, i.e. introduction, naturalization and invasion. The literature review revealed that 815 alien weed species occur in Finland of which 314 are regarded as naturalized. Based on their occurrence in different climate zones, the risk of naturalization of new harmful alien weed species was deemed low for those species not currently found in Finland, but higher for species occurring as casual aliens in Finland. In the latter group, 10 species of concern were detected. Exploration of the distribution patterns of naturalized species within...

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.

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...

Alpha-tocopherol and b-carotene in legume–grass mixtures as influenced by wilting, ensiling and type of silage additive
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.

Alpha-tocopherol and beta-carotene in legume-grass mixtures as influenced by wilting, ensiling and type of silage additive
Provedor de dados: 21
Autores: Lindqvist, H.; Nadeau, E.; Jensen, Søren K.
Effects of wilting, ensiling and type of additive on a-tocopherol 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 and ensiled without additive or with an inoculant or acid. Wilting decreased a-tocopherol concentration by 30% in the Bft + Ti mixture (P = 0.015). Untreated Bft + Ti silage had higher a-tocopherol content than red clover silages (56.9 vs. 34.2 mg/kg DM; P = 0.015). The a-tocopherol concentration of Bft + Ti forages increased during ensiling from 41.1 mg/kg DM in wilted herbage to 56.9, 65.2 and 56.8...

Autores: ROMET, L.; SEVERAC, G.
Aprés avoir été testée, sur un site en 2005 et neuf en 2006, la technique de protection physique des vergers de pommier contre le carpocapse nommée "Alt'Carpo" a été adoptée en vraie grandeur dans 15 vergers provençaux en 2007, et des tests complémentaires réalisés par ailleurs. Le suivi des 15 vergers a confirmé l'efficacité de la protection mono-rang (un filet par rang de pommier), et montré l'effet protecteur anti-grêle et ...coupe-vent. Un test en grande parcelle a comparé la maille "4 x 4" choisie sur les 15 vergers à celle d'un filet anti-grêle classique (plus large). La première a semblé meilleure, mais divers facteurs avaient handicapé le filet anti-grêle. Un test en grande parcelle a comparé les systèmes mono-rang et mono-parcelle (un seul filet...

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.

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.

Alternative management strategies to prevent and control endo-parasite diseases in sheep and goat farming systems - a review of the recent scientific knowledge
Provedor de dados: 21
Autores: Rahmann, Gerold; Seip, Hannah.
Infestation with gastro-intestinal nematodes (GIN) in small ruminants can cause server economic losses and endanger animal welfare. The development of organic farming systems, the increased public awareness for drug residues in agricultural products and the development of resistant strains of parasites have enforced the search for sustainable alternatives.    The aim of this review is to summarise the current scientific knowledge of alternative strategies to prevent and control endo-parasitic diseases in sheep and goat farming systems. Many scientific studies and projects have shown big discrepancies between results obtained under in vitro and in vivo conditions. Often research has been carried out under clinical conditions for extended periods before...

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...

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...

Ziel des 7. Fachgespräches "Pflanzenschutz im ökologischen Landbau" war es, Alternativen zur Kupferanwendung näher zu betrachten und Strategien für die zukünftige Entwicklung von Pflanzenschutzmaßnahmen im ökologischen Landbau zu diskutieren. Bei der Bekämpfung von Schadorganismen kann unter den Produktionsbedingungen des ökologischen Landbaus nur auf eine eng begrenzte Auswahl von Pflanzenschutzmitteln zurück gegriffen werden. Diese dürfen nur bei erwiesenem Bedarf verwendet werden und nur, wenn mit vorbeugenden Maßnahmen der Befall mit Schadorganismen nicht unter Kontrolle gehalten werden kann.

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.

Autores: Heid, Astrid; Hamm, Ulrich.
In Europa werden fast alle männlichen Ferkel routinemäßig kastriert, um die Entstehung von Ebergeruch zu verhindern. In der Regel erfolgt dieser Eingriff ohne Betäubung. Aktuell findet eine Diskussion über die Tierschutzrelevanz der betäubungslosen Ferkelkastration statt und ein Verbot dieser Praxis wird angestrebt. Daher müssen Alternativen zur betäubungslosen Kastration gefunden werden.   Ein wichtiger Faktor bei der Bewertung der Umsetzbarkeit der diskutierten Alternativen zur betäubungslosen Ferkelkastration ist die Bereitschaft der Verbraucher das so produzierte Fleisch auch zu kaufen. Der Beitrag gibt einen Überblick über den aktuellen Stand der Forschung zur Verbraucherakzeptanz der Alternativen zur betäubungslosen Ferkelkastration.

Autores: Tomasek, Jaroslav; Dvorak, Petr.
There were tested water extracts from Syringa vulgaris and Pyrethrum parthenium. They did not prove significant differences of decrease of the air attack of Colorado potato beetle (Leptinotarsa decemlineata), the activity of eggs – laying and the occurrence of larvae in comparison to the control. Interesting trends of lower-eggs lying and a lower larvae occurrence were discovered. The liquid spray against the late blight (Phytophthora infestans) did not significantly decrease neither occurrence of late blight or the yield.  The production of the bio-potatoes is only 0,2 % of all potatoes production in the Czech Republic. The aim of this experiment was to try alternative methods of regulation of Colorado potato beetle and late blight (the biggest harmfull...

At two sites in the Armenhof district, 10 km east of Fulda, Germany, dew samples were collected from June 1996 to June 1997 and investigated for free and protein bound amino acids. 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...

Ammonia volatilization, nitrogen in soil, and growth of barley after application of peat manure and pig slurry
Provedor de dados: 21
Autores: Mattila, Pasi K.
Peat is added to manure, because its low pH and capacity to adsorb ammonia (NH3) give it potential to reduce nitrogen (N) loss. Peat manure was prepared by mixing pig slurry with moderately humified Sphagnum peat. Less than 1% of applied ammoniacal N was volatilized as NH3 from peat manure and pig slurry within 8 h of surface application on clay loam soil according to JTI method. Incorporated manures showed even smaller N loss. The low volatilization was due to the adsorption of manure ammoniacal N by peat, and the infiltration of slurry into harrowed, moist clay soil. In another experiment, peat manure was applied on polypropylene fabric without soil contact. Within the first 3 days there was only 9% reduction in the ammoniacal N of peat manure, but the...

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...

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...

An extract of Penicillium chrysogenum elicits early defense-related responses and induces resistance in Arabidopsis thaliana independently of known signalling pathways
Provedor de dados: 21
Autores: Thürig, Barbara; Felix, Georg; Binder, Andreas; Boller, Thomas; Tamm, Lucius.
An aqueous extract of the mycelium of Penicillium chrysogenum (further called ‘Pen’ induced early defense-related responses such as an extracellular alkalinisation in cell cultures and ethylene production in leaf slices of numerous mono- and dicotyledon plant species, including Arabidopsis thaliana, tomato, tobacco and rice. The Pen-elicitor was sensitive to protease digestion but insensitive to other enzymes, suggesting that the elicitor-active region is a protein or a peptide. Reversed phase, ion exchange and size exclusion chromatography revealed that the Penelicitor is heterogeneous. This prevented further identification of the elicitor. Pen protected A. thaliana from a broad range of pathogens, including an oomycete (Hyaloperonospora parasitica), two...

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...

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...

An Observational Study on Early-Lactation Metabolic Profiles in Swedish Organically and Conventionally Managed Dairy Cows
Provedor de dados: 21
Autores: Fall, Nils; Gröhn, Yrjö T.; Forslund, Kristina; Essén-Gustafsson, Birgitta; Niskanen, Rauni; Emanuelson, Ulf.
The aim of this observational study was to compare indicators of energy balance in early lactation in organically managed dairy cows (OMC) and conventionally managed dairy cows (CMC) under field conditions. The diets of OMC and CMC differ as a consequence of the rules and principles of organic dairy farming. The study was based on clinical examinations and blood samples from cows within the range from 2 wk prepartum to 6 wk postpartum, collected from 20 organic and 20 conventional dairy farms with 3 visits at each farm. The farms were located in a southeastern area of Sweden and ranged in size from 45 to 120 cows. The blood parameters selected to reflect energy metabolism were nonesterified fatty acids, β-hydroxybutyrate, glucose, and insulin. At clinical...

An organic and environmentally friendly growing system for greenhouse tomatoes
Provedor de dados: 21
Autores: Sørensen, Jørn Nygaard; Thorup-Kristensen, Kristian.
Tomato plants were grown in open beds, confined beds, or combined beds with compost based on clover grass hay, deep litter and peat. Plants grown in the confined and the combined beds produced the earliest tomatoes. During the first five weeks of harvest, approximately 18% of the fruits produced in confined beds developed blossom end rot. This disorder was hardly developed in the other growing systems. After five weeks of harvest, these differences in fruit production were unchanged or even increased. Plants grown in the confined beds produced significantly less fruit load compared with the other bed types, especially in 2003. Application of supplemental fertilizer did not significantly increase the fruit production in any year.

Provedor de dados: 21
Autores: VEYSSET, P.; GLOUTON, J.; BEBIN, D.; BECHEREL, F.
in the Massif Central. An organic suckler cattle farm network was set up in order to establish technical and economic references. In 2004, 22 farms were monitored (13 of which had been monitored since 2001). All of these farms are located in economically-depressed areas. One hundred percent of the fodder area is under grassland. Annual crops (cereals and a cereal/pulse mix) take up 13% of the farm area and are used as livestock feed. The stocking rate (1 Livestock Unit/ha of fodder area) is 20% lower on organic farms than on conventional farms. Organic farms use 33% less concentrates per LU, and the meat production/LU is 16% lower than for conventional farms. The poorly structured organic beef market forces organic farmers to sell most of their animals...

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...

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...

Anaerobic mono-digestion of lucerne, grass and forbs - Influence of species and cutting frequency
Provedor de dados: 21
Autores: Wahid, R; Feng, L; Cong, WF; Ward, A; Møller, HB; Eriksen, J.
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...

Análise agroecológica de dois paradigmas modernos.
Provedor de dados: 21
Autores: Goulart, Fernando; Vandermeer, John; Perfecto, Ivette; Matta-Machado, Rodrigo P.
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. Através da crítica agroecológica, ambas as correntes, a...

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.

Analysis of the spatial distribution of organic farming in the Provence-Alpes-Côte d’Azur (PACA) region of France: building a methodology for observation and prospective
Provedor de dados: 21
Autores: GENIAUX, G.; LAMBERT, M.; BELLON, S.
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...

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...

Analytical authentication of organic products: an overview of markers
Provedor de dados: 21
Autores: Capuano, E.; Boerrigter-Eenling, R.; van der Veer, G.; van Ruth , S.M.
Consumers' interest in organic foods is increasing and so is the need for robust analytical tools for their authentication. This review focuses on the most promising biomarkers/analytical approaches that are available for the authentication of organic produce. Food products have been subdivided into two groups: foods of plant origin (crops) and foods of animal origin (meat, milk and dairy products, eggs and fish). For each food category the most suitable biomarkers are presented and their potential for authentication is discussed. In the light of current knowledge, it is unlikely that the authentication of organic food products can be attained by the measurement of a single marker. Analytical approaches based on the measurement of multiple markers and/or...

Anbauverfahren mit Körnerleguminosen im Ökologischen Landbau [Production methods for legume grains in organic agriculture]
Provedor de dados: 21
Autores: Pommer, G.
Für viehlose Ökobetriebe ist beim Anbau von Körnerleguminosen deren Ertragsleistung und die Nachfruchtwirkung auf den sich anschließenden Getreideanbau von Belang. Futtererbse und Ackerbohne erzielten hohe Erträge von über 50 dt/ha, während von der Lupine nur 25 dt/ha geerntet wurden. In der Nachfruchtwirkung auf Winterweizen und nachfolgend Winterroggen konnten nur geringfügig Unterschiede festgestellt werden. Veränderungen in der Anbautechnik der Körnerleguminosen durch engere Reihenabstände oder Zwischenfrüchte führten zu keinen signifikanten Einflüssen auf den Ertrag der Körnerleguminosen oder auf die Erträge der nachfolgenden Getreidearten.

Wheat genetic resources may be grown in organic farming systems or in less favourable areas for bread wheat species. Characteristics of hulled wheat species (23 varieties of einkorn, emmer wheat, spelt wheat) were studied and evaluated within a two-year trial period (which was executed on certified organic fields) and they were compared to characteristics of landraces and modern bread wheat varieties. The main aim of our study was to evaluate the potential uses of genetic resources of wheat in organic farming. The hulled wheat species were resistant to mildew and brown rust. Their grains were less contaminated with DON than the grains of the control varieties. The grain yield rate was reduced. Per hectare crude protein yield was higher in spelt and emmer...

Animal Health and Welfare during transition to organic dairy production: problems, priorities and perspectives
Provedor de dados: 21
Autores: Vaarst, M.; Alban, L.; Mogensen, L; Thamsborg, S.M.; Kristensen, E.S.
During the past few years, organic dairy farming has grown dramatically in Denmark. Consequently, an increasing number of people are encountering this method of production for the first time. Amongst these, many veterinarians have suddenly had to deal with organic herds in their home district, and, meeting examples of poor animal welfare, they have recently started to express some concerns.  Against this background, a so-called “Synthesis of Knowledge” project was initiated  to examine the health and welfare of dairy cattle and the use of medication in the transition to organic production. The aim of the project was to investigate associated problems from the point of view of the dairy herd. Based on qualitative research interviews with vets and...

Animal Health and Welfare in Organic Agriculture
Provedor de dados: 21
Autores: Philipps, Lois.
A brief report is given of the 4th Network for Animal Health and Welfare in Organic Agriculture (NAWHOA) workshop at Wageningen in the Netherlands, held in March 2001.  The workshop focussed on breeding (especially dairy, pigs and poultry) and feeding, as opposed to yield and productivity, with the emphasis on food quality. Feeding was discussed from two angles: feeding for production, and feeding to protect the animal from disease or parasitic infection.    A vision of the future was described, in which higher prices are gained for fewer animals, better housed and with a regional approach to breeding, processing and marketing.

Animal health and welfare in organic livestock production in Europe– current state and future challenges
Provedor de dados: 21
Autores: Hovi, Malla; Sundrum, Albert; Thamsborg, M.S.
Existing data on animal health and welfare in organic livestock production systems in the European Community countries are reviewed in the light of the demands and challenges of the recently implemented EU regulation on organic livestock production. The main conclusions and recommendations of a three-year networking project on  organic livestock production are summarised and the future challenges to organic livestock production in terms of welfare and health management are discussed. The authors conclude that, whilst the available data are limited and the implementation of the EC regulation is relatively recent, there is little evidence to suggest that organic livestock management causes major threats to animal health and welfare in comparison with...

Continuous development is needed within the farm to reach the goal of good animal health and welfare in organic livestock farming. The very different conditions between countries call for models that are relevant for different farming types and can be integrated into local practice and be relevant for each type of farming context. This article reviews frameworks, principles and practices for animal health and welfare planning which are relevant for organic livestock farming. This review is based on preliminary analyses carried out within a European project (acronym ANIPLAN) with participants from seven countries. The process begins with gathering knowledge about the current status within a given herd as background for making decisions and planning future...

Organic livestock production is a means of food production with a large number of rules directed towards a high status of animal welfare, care for the environment, restricted use of medical drugs and the production of a healthy product without residues (pesticides or medical drugs). The intentions of organic livestock production have been formulated by the International Federation of Organic Agriculture Movements (IFOAM) and were further implemented by EU regulation 2092/91 in the year 2000. The consequences of these rules for the health of the animals were not yet fully anticipated at the time these regulations were made and it has become clear that in some cases the rules are not clear enough thereby even hampering the development of the production...

Sixteen meat sheep farms (nine conventional and seven organic) in the centre of France were surveyed to evaluate their economic and production performances (previous interviews) and their strategies related to animal health with particular attention to internal parasites (present interview on health strategies). The organic farms were surveyed in mid-September 2006 and the conventional ones in October 2007. Each interview (1½ or 2 h) included a visit of the farm (with the collection of faeces for evaluation of internal parasites), followed by an open discussion on sheep production and health problems, and parasitic infections, in particular. The discussion was recorded and then transcribed into a word processor file and analysed. The farmers agreed on the...

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...

Provedor de dados: 21
Autores: Andersen, Laura Mørch.
Marginal willingness to pay for eggs carrying labels indicating different productions methods is estimated using Danish purchase data on individual level. Among other things the labels indicate environmental features and different levels of animal welfare for the hens that produce the eggs. Results show that consumers are generally willing to pay for labels indicating animal friendly production methods. It also appears that consumers living in urban areas are willing to pay more for animal welfare than people in rural areas and that people who perceive the level of animal welfare in organic eggs as higher are willing to pay more not only for organic eggs but also for other labels indicating increased animal welfare. The age of the main buyer has no...

Autores: Sørensen, J.T.; Sandøe, P.; Halberg, N.
A proposal as to how to combine animal welfare with other goals using an ethical account for livestock farming is presented. The purpose of an ethical account is to report on the consequences of individual events and routine methods on the farm for all affected parties, and to ensure that the farmer is conscious of his ethical priorities. A procedure for an annual account is presented and the concepts involved in it are explained. Welfare assessment involves information from four sources: the system, the system’s application, animal behaviour and animal health. Welfare assessment is an aid for operational management as well as for strategic planning. This ethical account was developed in collaboration with twenty livestock farms over a period of three...

Animal welfare versus food quality: Factors influencing organic consumers' preferences for alternatives to piglet castration without anaesthesia
Provedor de dados: 21
Autores: Heid, Astrid; Hamm, Ulrich.
Surgical piglet castration without pain relief has been banned in organic farming in the EU since the beginning of 2012. Alternative methods therefore need to be implemented that improve animal welfare and solve the underlying problem of boar taint. This paper explores German organic consumers' preferences for piglet castration without pain relief and three alternative methods. In an innovative approach using a multi-criteria decision making procedure, qualitative data from focus group discussions were compared with quantitative results from Vickrey auctions. Overall, participants preferred all alternatives to castration without pain relief. Different aspects influenced willingness-to-pay for the methods.

Animal-friendly production systems may cause re-emergence of Toxoplasma gondii
Provedor de dados: 21

Toxoplasmosis is still one of the most common parasitic infections in the world, although in Europe improvements in hygiene and the introduction of ‘total’ indoor farming in livestock production have rapidly diminished the problem during the past decades. As a result of public dislike, however, introduction of alternative and more acceptable animal-friendly livestock production systems including outdoor access are gaining ground. Potentially these systems can lead to increased prevalence of certain zoonotic diseases, including Toxoplasmosis. To retain prevalence of this disease in humans at current  levels, emphasis should be on disease control at farm-level.

Annual maize and perennial grass-clover strip cropping to produce biomass for bioenergy – within an organic farming approach
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 maize (Zea mays L.). Maize was established after soil incorporation of a 1st-year grass-clover in a 6-m wide strip, whereas grass-clover was 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 when growing maize in close proximity to grass-clover total dry matter production was reduced with about 50% compared to &gt;150 cm distance. However, it was partly compensated by greater yields by especially the 50-100 cm harvest. In contrast there was no significant...

Anthelmintic effect and intake dynamics of oak (quercus spp.) and walnut (juglans regia) foliage in goats
Provedor de dados: 21
Autores: Heckendorn, F.; Lèbre, A.; Destailleur, V.; Bouy, M.; Spiegler, V.; Lehmann, S.; Hensel, A.
Oak and Walnut are both of ethnoveterinary importance, especially for anthelmintic treatment of ruminants [1,2]. H2O and EtOH-water (1:1) extracts of oak and walnut foliage were used for phytochemical profiling and for in vitro assays with Caenorhabditis elegans and gastrointestinal nematodes (GIN). Oak extracts contained mainly tannins, walnut extracts were dominated by flavonoids. Oak EtOH extract caused significant lethal effects in adult C. elegans (LC50 1.5 mg/mL); motility of GIN L3 larvae was reduced by the EtOH extract but at substantially higher concentrations. Egg hatching was inhibited by both, the oak H2O and EtOH extract. In vivo: 42 lactating Alpine goats carrying natural GIN infections were allocated to 3 feeding groups: oak, walnut 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)...

Provedor de dados: 21
Autores: Simonsen, Marie-Louise Rugholm; Enkegaard, Annie; Bang, Camilla Nordborg; Sigsgaard, Lene.
Laboratory experiments were performed with adult female Anthocoris nemorum (Linnaeus) (Heteroptera: Anthocoridae) at 20°C ±1°C, L16:D8, 60-70% RH to determine voracity and preference on cabbage aphids (Brevicoryne brassicae L.) (Hemiptera: Aphididae), diamondback moth larvae (Plutella xylostella L.) (Lepidoptera: Plutellidae) and Western flower thrips (Frankliniella occidentalis Pergande) (Thysanoptera: Thripidae) (model species for cabbage thrips (Thrips angusticeps Uzel) (Thysanoptera: Thripidae)). When offered individually, A. nemorum readily accepted all three species with no significant differences in consumption. When aphids and moth larvae were offered simultaneously, A. nemorum showed preference for the latter (numbers eaten and biomass consumed)....

Antibiotic use by farmers to control mastitis as influenced by health advice and dairy farming systems
Provedor de dados: 21
Autores: Poizat, Axelle; Bonnet-Beaugrand, Florence; Rault, Arnaud; Fourichon, Christine; Bareille, Nathalie.
Mastitis is a bacterial disease common in dairy farms. Although knowledge about mastitis and its optimal technical management and treatment is now available, some dairy farmers still use antibiotics in inappropriate ways. Antibiotic use by farmers can be influenced by personal restraints and motivations, but it can be assumed that external drivers are also influential. The main purpose of this article is thus to analyse the choices of antibiotic and alternative medicine use for mastitis treatment and investigate the possible influence of two unexplored external drivers in dairy farms: (i) the health advice offered to farmers by farm advisors and veterinarians, (ii) the dairy farming system, as defined by combining the market valuation chosen for the milk,...

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...

Antioxidant effects of ryegrass phenolics in lamb liver and plasma
Provedor de dados: 21
Autores: López-Andrés, P.; Luciano, G.; Vasta, V.; Gibson, T.M.; Scerra, M.; Biondi, L.; Priolo, A.; Mueller-Harvey, I.
Sixteen lambs were divided into two groups and fed two different diets. Eight lambs were stall-fed with a concentrate-based diet (C), and the remaining eight lambs were allowed to graze on Lolium perenne (G). The antioxidant status was measured in the liver and plasma samples before and after solid-phase extraction (SPE) to probe the antioxidant effects that grass phenolic compounds may have conferred onto the animal tissues. The liver and plasma samples from grass-fed lambs displayed a greater antioxidant capacity than the tissues from C lamb group, but only if samples had not been passed through SPE cartridges. Finally, the feed and animal tissues, which had been purified by SPE, were analysed by liquid chromatography combined with mass spectrometry...

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...

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.

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...

Autores: Symanczik, Sarah; Gisler, Michelle; Thonar, Cécile; Schlaeppi, Klaus; van der Heijden, Marcel; Kahmen, Ansgar; Boller, Thomas; Mäder, Paul.
Naranjilla (Solanum quitoense) is a perennial shrub plant mainly cultivated in Ecuador, Colombia, and Central America where it represents an important cash crop. Current cultivation practices not only cause deforestation and large-scale soil degradation but also make plants highly susceptible to pests and diseases. The use of arbuscular mycorrhizal fungi (AMF) can offer a possibility to overcome these problems. AMF can act beneficially in various ways, for example by improving plant nutrition and growth, water relations, soil structure and stability and protection against biotic and abiotic stresses. In this study, the impact of AMF inoculation on growth and nutrition parameters of naranjilla has been assessed. For inoculation three European reference AMF...

Application of processed organic municipal solid waste on agricultural land - a scenario analysis
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.

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...

Applying ant hygiene: can ants protect crops against diseases?
Provedor de dados: 21
Autores: Offenberg, Joachim; Damgaard, Christian.
1. Ants provide ecosystem services to agriculture by controlling arthropod pests. Plant diseases, however, can be more detrimental to plant production than herbivory. Here, we investigate a new type of potential ant service – namely that ant hygiene may extend beyond the ants themselves to also cover their host plants, potentially resulting in protection against plant diseases.   2. We review the literature for support to the idea that ant hygiene, including ant-derived antibiotics, can protect plants against pathogens, and we provide empirical pilot data from a Danish apple plantation further supporting this idea.  3. In a literature search, we found nine studies showing ants reducing pathogen incidence on host plants. These studies cover nine ant species...

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...

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...

Provedor de dados: 21
Autores: Stamer, Andreas; Bär, Markus.
L’alimentation animale s’apprête à subir une pénurie de protéines: Toujours plus d’animaux pour toujours plus d’hommes qui mangent toujours plus de viande et de poisson consomment toujours plus d’aliments protéinés. Le FiBL suit pour l’alimentation des poissons d’élevage une approche très prometteuse: Nourrir des larves de mouches avec des déchets de l’industrie agroalimentaire et les utiliser ensuite pour nourrir les poissons.

Autores: Strüber, Klaus.
Das Projekt aus 2003 (SP 29) wurde in 2004 fortgesetzt. Die Flächen wurden vergrößert, dementsprechend stiegen die Einsatzstunden an und neue Geräte wurden getestet. Auf einem größeren Betrieb in Norwegen wurden Vergleichsdaten unter anderen Bedingungen erhoben.  Im Rechts/Links Versuch zu Bodenverdichtung wurden signifikante Unterschiede im Boden (pH-Wert, Verdichtung) und der Pflanze (Chemie, Physik, Bildekräfte) zu Gunsten des Pferdes ermittelt.       Pferde erzielten gute Leistungen in Gemüsepflege. Die geringe Dieselersparnis würde höher ausfallen, wenn Pferde auch in der Grundbodenbearbeitung eingesetzt werden würden.

Arbuscular mycorrhizae in a long-term field trial comparing low-input (organic, biological) and high-input (conventional) farming systems in a crop rotation
Provedor de dados: 21
Autores: Mäder, Paul; Edenhofer, Stephan; Boller, Thomas; Wiemken, Andres; Niggli, Urs.
Arbuscular mycorrhizal (AM) root colonization was studied in a long-term field trial in which four farming systems currently in use in Switzerland were continuously applied to a randomized set of plots at a single field site from 1978 till 1993. There were two low-input farming systems (organic and bio-dynamic) and two high-input (conventional) farming systems (according to Swiss guidelines of integrated plant production with and without farmyard manure). The systems had an identical 7-year crop rotation and tillage scheme and differed essentially only in the amount and type of fertilizer supplied and in plant protection management. The percentage of root colonization by AM fungi was determined in field samples 2–3 times over the growing season in crops in...

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...

Are standards and regulations of organic farming moving away from small farmers' knowledge?
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.

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...

Arsenic and heavy metal concentrations in agricultural soils in South Savo province
Provedor de dados: 21
Autores: Mäntylahti, Väinö; Laakso, Pirkko.
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...

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...

Arthropod pest management in organic crops
Provedor de dados: 21
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...

Provedor de dados: 21
Autores: Gavioli, Felipe Rosafa; Costa, Manoel Baltasar Baptista.
A partir da emergência da ideia de sustentabilidade, a agricultura adquiriu novas conotações, associadas não apenas ao aspecto produtivo, mas também à conservação dos recursos naturais e dos territórios rurais, em um reconhecimento de sua multifuncionalidade. Com base nesta noção, que valoriza as funções socioambientais desempenhadas pelas famílias rurais e pelas agriculturas praticadas, o presente artigo analisa um assentamento rural no estado de São Paulo, buscando identificar quais são e de que forma se expressam as funções para além da produção neste território particular. Por meio de uma metodologia de cunho quali-quantitativo, observou-se que, no assentamento em foco, a agricultura encerra em si questões de coesão territorial, manutenção da segurança...

As perspectivas da pequena produção familiar na agricultura constitui um tema controvertido na sociologia e na economia rural. 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.

The transmission of Ascaris suum was studied in outdoor reared pigs. From May to June, 2001 6 farrowing paddocks were naturally contaminated with A. suum using experimentally infected seeder pigs. Early July, 1 sow farrowed on each paddock. One piglet per litter was slaughtered every second week starting week 3 post partum (p.p.) for registration of liver white spots and recovery of A. suum from the lungs and the small intestine. The last pigs were slaughtered week 19 p.p. Faeces was examined for eggs and blood was analysed for A. suum specific antibodies. Weaning took place week 7 p.p. by removing the sow. Paddock infection levels were estimated by regular examination of soil samples and in late June and late November using parasite naïve tracer pigs....

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...

Aspekte der Strohmulchanwendung im ökologischen Kartoffelanbau – II.Wirkung auf Potato Virus Y, Leptinotarsa  decemlineata und Knollenertrag
Provedor de dados: 21
Autores: Döring, Thomas F.; Heimbach, Udo; Thieme, Thomas; Saucke, Helmut.
In Praxisversuchen wurde über drei Jahre der Einfluss von Strohmulch auf das Auftreten von PVY (Potato virus Y), den Befall mit dem Kartoffelkäfer (Leptinotarsa decemlineata) und den Knollenertrag in ökologisch angebauten Kartoffeln untersucht. Strohmulch führte in drei von 17 Experimenten zu einer signifikanten Reduktion von PVY, und in weiteren sieben Versuchen gab es einen nicht-signifikanten Trend zur erminderung von PVY. Der Effekt von Strohmulch auf PVY scheint vom allgemeinen Infektionsniveau abzuhängen, welches je nach Jahr, Standort und Sorte unterschiedlich war. So gab es in den Jahren 2002 und 2004 bei allgemein hohem Infektionsdruck eine konsistente PVY-Verminderung. Im Gegensatz dazu konnte im Jahr 2003, bei nur sehr geringem Infektionsdruck,...

Aspekte zur Unkrautregulierung im ökologischen Landbau [Aspects for weed management in organic farming]
Provedor de dados: 21
Autores: Schleuß, Uwe.
Ein zentrales Problem im ökologischen Pflanzenbau ist es, die Schwierigkeiten bei der Regulierung der Unkrautflora in den Griff zu bekommen. Neben den direkten Verfahren der Unkrautregulierung (biologische, thermische oder mechanische Maßnahmen), kommen im ökologischen Landbau vor allem indirekten Maßnahmen eine besondere Bedeutung zu. Neben der Fruchtfolge sind weitere indirekte Unkrautregulierungsmaßnahmen, wie Lichtentzug, Saatgutreinigung, Saatgutqualität, Bodenbearbeitung, Standraum der Kulturpflanzen und Sorteneigenschaften zu nennen.

The aim of this trial was to study the effect of organic housing system on the behaviour, productive performance and the qualitative characteristics of eggs. The experiment was conduced directly in the field on Hy-Line laying hens from the beginning of the productive period (17 weeks of age) till the end of productive career. The animals were divided in two homogeneous groups and assigned to the following housing system: control, conventional cage (18 bird/m2) and organic 6 birds m2 in a covered straw-bedded house with access to a paddock (4 m2/bird). A standard feed with the same nutritive characteristics was given ad libitum to the chickens. For the organic, more  than 80% of the ingredients (maize, wheat and whole soybean) were organically grown, as...

Assessing a treatment on the basis of an individual or a group. An example: the homeopathic treatment of digestive-tract strongyles in sheep
Provedor de dados: 21
Autores: TABEL, J.; SAUVE, C.; CORTET, J.; TOURNADRE, H.; THOMAS, Y.; CABARET, J.
Homeopathic treatments, widely used in organic farming, remain unevaluated. Assessment is difficult since the individuals that respond to treatment are not identified, although it is central to the concept of homeopathic treatment. Classifying lambs into those to be treated (since they have high parasitic infection rate or poor production performances) or that should remain untreated (in other words, even when treated, they will not benefit from treatment) is not simple. The identification of lambs to be treated can be based on parasitological examinations (eggs per gram of faeces), clinical (anaemia or diarrhoea)or production-related (weight gain) results. The classification of lambs was a posteriori and based on dendrograms using UPGMA (unweighted...

Autores: Jones, P. J.; Sok, J.; Tranter, R. B.; Blanco-Penedo, I.; Fall, N.; Fourichon, Christine; Hogeveen, H.; Krieger, M. C.; Sundrum, A.
Many believe the health status of organic dairy herds in Europe should be improved to meet consumers’ and legislators’ expectations to improve animal welfare. This paper reports on a study in four countries that examined dairy farmers’ intentions towards improving the health status of their organic herds through the use of the Theory of Planned Behaviour. It was found that farmers across the countries were positive about taking additional preventative measures to improve the health status of their herds. They believed this would not only improve herd physical performance, such as milk yield and fertility, but also achieve greater cost effectiveness and improved job satisfaction for them. Most study farmers would implement a tailored package of improvement...

Assessing impacts of organic production on pork and beef quality
Provedor de dados: 21
Autores: Sundrum, Albert.
Organic livestock farming is based on a low input production method, aiming to provide products of a high product and process quality rather than maximizing production. The production of a high meat quality corresponds to the expectations of consumers who are both seeking a premium product and who are willing to pay premium prices. This review focuses on the question of whether organic pork and beef production currently meet consumer demands, and it elaborates the potentials and limitations for producing high-quality meats under the current organic framework.   Although defined by specific and basic guidelines, organic livestock production is characterised by largely heterogeneous farming conditions that allow for huge differences in the availability of...

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...

Assessing soil biological characteristics: a comparison of bulk soil community DNA-, PLFA-, and Biolog-analyses
Provedor de dados: 21
Autores: Widmer, F.; Fliessbach, A.; Laczkó, E.; Schulze-Aurich, J.; Zeyer, J.
Soil microbiological analyses may serve as a means for assessing soil characteristics. Standard microbiological culture-techniques, however, leave over 90% of the microorganisms in the environment unaccounted for. Several more recently developed analytical techniques such as DNA, phospholipid fatty acid (PLFA), and community level substrate utilization (CLSU) Ængerprints allow for more detailed analyses of soil microbial communities. We applied analyses of (1) community DNA with PCR and restriction fragment length polymorphism (RFLP), (2) community PLFAs with gas chromatography and mass spectrometry, and (3) CLSU with Biologe gram-negative-plates, to evaluate the biological characteristics of three soils used in pesticide degradation studies. Each of these...

Sustainable development calls upon the farming sector to commit itself to the transmission of natural resources to future generations. The INRA research team of Mirecourt studies the design of environmentally-friendly farming systems. The design of these systems is based on a multitude of objectives, and their evaluation is determined by a wide range of criteria. This work aims at determining the practical conditions for implementing agricultural systems considered to be sustainable from an environmental point of view. Two organic dairy systems considered to be environmentally friendly ex ante have been designed in partnership with the staff of the INRA research team of Mirecourt. A grazing dairy system and a mixed-crop dairy system are being...

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...

This study aimed to gain insight into the microbial quality, safety and bacterial community composition of black soldier fly larvae (Hermetia illucens) reared at different facilities on a variety of organic waste streams. For seven rearing cycles, both on laboratory-scale and in large-scale facilities at several locations, the microbiota of the larvae was studied. Also samples of the substrate used and the residue (= leftover substrate after rearing, existing of non-consumed substrate, exuviae and faeces) were investigated. Depending on the sample, it was subjected to plate counting, Illumina Miseq sequencing and/or detection of specific food pathogens. The results revealed that the substrates applied at the various locations differed substantially 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....

Autores: Zanoli, Raffaele; Gambelli, Danilo; Solfanelli, Francesco; Padel, Susanne.
The purpose is to provide an analysis of the risk factors influencing non-compliance in UK organic farming.  The paper uses a formal econometric model of risk analysis to provide empirical evidence on the determinants of non-compliance in organic farming. A panel of data from the archives of the largest control body in the UK for 2007-2009 is used, and specific analyses are performed for two types of non-compliances. A zero inflated count data model is used for the estimation, taking into account the fact that the occurrences of non-compliance are very sparse.  Results show the existence of strong co-dependence of non-compliant behaviours (i.e. the occurrence of major and critical non-compliance increases the probability of occurrence of the minor one;...

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...

The main objective of "CedABio" was to estimate the environmental and socioeconomic benefits  anticipated in the bovine farming systems adopting an organic production mode. Beyond some obvious  advantages, the goal was to measure and ascertain the real contributions of a change to organic  farming for the dairy and beef farms. To lead this assessment, strong and technically accessible  indicators were selected, tested, and then looked for in 144 livestock farms, located in varied contexts to  take into account territorial diversity. Half of the farms were in organic mode. Their results are compared  with the other half producing in conventional mode, situated in the same zones, with similar structures.  The results and the observations performed in this...

Autores: Rasmussen, Jesper; Nørremark, Michael; Bibby, Bo Martin.
Objective assessment of crop soil cover, defined as the percentage of leaf cover that has been buried in soil due to weed harrowing, is crucial to further progress in post-emergence weed harrowing research. Up to now, crop soil cover has been assessed by visual scores, which are biased and context dependent.  The aim of this study was to investigate whether digital image analysis is a feasible method to estimate crop soil cover in the early growth stages of cereals. Two main questions were examined: (1) how to capture suitable digital images under field conditions with a standard high-resolution digital camera and (2) how to analyse the images with an automated digital image analysis procedure. The importance of light conditions, camera angle, size of...

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...

The debate over agricultural sustainability continues due to the challenges of reducing externalities of intensive farming methods and preserving vital natural capital, but many definitions of sustainability are too wide to allow for a prioritized assessment. This paper uses a more narrow definition of agricultural sustainability focusing on the functional integrity of a system to highlight specific aspects of vital importance for the long-term resilience and reproducibility of agricultural systems. Key areas of resource sufficiency are also identified. Based on a review of scientific literature the relative sustainability of organic agriculture is assessed with a focus on environmental impact and resourceuse in Europe and North America.

Associative Deadlocks and Transformative Capacity: Engaging in Australian Organic Farm Industry Development
Provedor de dados: 21
Autores: Halpin, Darren; Daugbjerg, Carsten.
Recent work on industry policy argues that group and state capacity are important in underpinning (or undermining) the capacity to govern industrial development. Put simply, group capacity - alongside state capacity - is deemed an important ingredient in any recipe for (re)developing national industry. This article further develops the literature on governance and transformative capacity, adding deliberative networking as a key facet. Examining the development of the organic farming sector in Australia, it is argued that the absence of transformative capacity frustrates development. Specifically, although the state has slowly come to see a need for some interaction and facilitation of organic industry development, particularly of a national domestic...

Indkomst, udvikling, nytte, lykke og velfærd er alle begreber, som kan have mange og upræcise betydninger. Så længe de er luftige og svært målbare, er de ikke særligt brugbare. Man må forsøge at gøre dem præcise, veldefinerede og målelige, og det er hvad økonomer har kæmpet for i mere end hundrede år. Nogle af begreberne er dog så veletablerede og veldefinerede, at de ofte får lov at stå alene. En troværdig samfundsforsker må prøve at få et overblik over hele spektret af mulige målbare begreber og indikatorer og med åbent sind analysere fordele og ulemper ved de forskellige begreber, definitioner og beregninger.

Autores: Ramos, Fabricio Tomaz; Nunes, Maria Cândida Moitinho; Campos, Daniela Tiago da Silva; Ramos, Denis Tomás; Maia, João Carlos de Souza.
O uso conservacionista do solo tem-se instituído tema de crescentes discussões devido à remoção de biomas e seu posterior uso agrícola. Hipoteticamente, acredita-se que a avaliação da qualidade agronômica de um solo qualquer, por meio de indicadores conjugados, em vez de interpretações isoladas, é mais adequada para caracterização do efeito antrópico em sistemas agrícolas. Em função disso, objetivou-se diagnosticar alterações em um LATOSSOLO VERMELHO-AMARELO Distrófico típico sob monocultivo de soja e cerrado nativo com base em indicadores físicos e microbiológicos, amostrados de modo inteiramente casualizados na profundidade de 0 a 10 cm.

Attending the First Organic Agriculture Course: Rudolf Steiner’s Agriculture Course at Koberwitz, 1924
Provedor de dados: 21
Autores: Paull, John.
Rudolf Steiner’s Agriculture Course held at Koberwitz (now Kobierzyce, Poland) in 1924 was arguably the world’s first organic agriculture course - although the terms ‘biodynamic agriculture’ and ‘organic farming’ appeared in the decades that followed. Ehrenfried Pfeiffer and others have stated that there were about 60 attendees at the course, while Rudolf Steiner and others have stated that there were about, or more than, 100 attendees. The present study examines the original attendance records to reveal that there were 111 attendees. There were 30 women and 81 men. They came from six countries: Germany (N=61); Poland (N=30); Austria (N=9); Switzerland (N=7); France (N=2); and Sweden (N=2). Of the 60% of enrolees who declared a profession, 38 could be...

Aufgelöste Bauweise in der Sauenhaltung
Provedor de dados: 21
Autores: Simantke, C.
In natürlicher Umgebung leben Sauen mit ihren Ferkeln in Gruppen und suchen zum Wühlen und Fressen, zum Ruhen und zum Koten verschiedene Orte auf. In der bisher üblichen, kompakten Stallbauweise ist eine Trennung dieser Lebensbereiche nur ungenügend zu realisieren. Hier bietet sich eine aufgelöste Bauweise an, die den Bedürfnissen der Tiere und der mit ihnen arbeitenden Menschen so weit wie möglich entgegen kommt. Sie ist kostengünstig und lässt sich gut in Altgebäude integrieren.

Autores: Géneau, Céline; Schlatter, Christian; Daniel, Claudia.
Pollen beetles (Meligethes sp.) are important pests in oilseed rape (Brassica napus). In  our study we wanted to determine which landscape structures have an influence on pollen beetle  population in early spring. The dynamics of pollen beetle population and the damages on rape were  studied on field scale level with 100 sampling points per field and on landscape scale level with 18  organic oilseed rape fields which differed by the complexity of the surrounding landscapes. The  number of pollen beetle was strongly correlated with the distance to a forest. At the beginning of  the flight period more pollen beetles were found close to the forest, later they migrated to the rest of  the field. In addition, agricultural practices appeared to be determinant...

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...

Auswirkungen der EU-Osterweiterung auf den Öko-Landbau in Ost und West: Erste Ergebnisse.
Provedor de dados: 21
Autores: Zander, Katrin; Nieberg, Hiltrud.
Der ökologische Landbau in den neuen Mitgliedsländern der EU hat in den letzten Jahren eine sehr dynamische Entwicklung erfahren. Durch die verstärkte Förderung hat sich die Wirtschaftlichkeit des ökologischen Landbaus nach dem Beitritt zur EU deutlich erhöht. Westeuropäische Erzeuger fürchten die zunehmende Konkurrenz. Mittelfristig werden die östlichen Ökolandwirte ihre Kostenvorteile nur nutzen können, wenn sie Produktivitätsfortschritte erzielen. Auf der Absatzseite sind deutliche Investitionen in die Infrastruktur und in eine effektive Öko-verarbeitung und -Vermarktung erforderlich. Eine steigende inländische Nachfrage in Folge wirtschaftlicher Entwicklung kann den Exportdruck zusätzlich reduzieren, so dass mit einer „Schwemme“ mittel- und...

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.

Autores: Luka, Henryk; Pfiffner, Lukas; Niggli, Urs.
Carabid populations (species diversity and abundance) in different crops were investigated during the period from April to July 1993 to 1995. The study was carried out on two farms in North-Western Switzerland. Nine fields with winter cereals (4x wheat, 2x spelt, 2x barley, lx rye), three rape fields, five spring cultures (3x maize, lx soybeans, lx potatoes) and an arable meadow were studied. In winter cereals, more carabid species were found than in spring cultures. In barley, we recorded fewer carabid species and individuals, larger numbers of hygrophilaus carabids and a more even population structure than in the other cereals. In rape, we recorded the highest numbers of carabid species and individuals, and very large numbers of Amara similata and A...

Authentication of Organic Milk Using δ13C and the  alpha-Linolenic Acid Content of Milk Fat
Provedor de dados: 21
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...

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...

Authentifizierung von Bio-Milch im Labor
Provedor de dados: 21
Autores: Molkentin, Joachim.
In Deutschland ist die Nachfrage nach Bio-Lebensmitteln in den letzten Jahren stetig gestiegen. So erhöhte sich der Absatz von Bio-Trinkmilch in 2007 im Vergleich zum Vorjahr erneut kräftig um 34 Prozent (ZMP, Bonn) und der Bio-Anteil beträgt inzwischen bei Frischmilch knapp elf Prozent. Aufgrund sporadisch resultierender Lieferengpässe bei Bio-Milch sowie der vorhandenen Handelspreisdifferenz besteht zunehmend ein potenzielles Risiko der Falschdeklaration konventionell erzeugter Milch als Bio-Ware.

Automated generation of guidance lines for operational  field planning
Provedor de dados: 21
Autores: Hameed, I.A.; Bochtis, D.D.; Sørensen, C.G; Nørremark, M.
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...

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...

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. A neural network classifier, working on 17 features...

Autumn acaricide applications as a new strategy to control the pear leaf blister mite Eriophyes pyri
Provedor de dados: 21
Autores: Daniel, Claudia; Linder, Christian; Wyss, Eric.
The pear leaf blister mite Eriophyes pyri (Pagenstecher) causes severe damage to pear leaves and fruits. As mites are well sheltered from exposure to plant protection agents during summer and acaricide efﬁcacy is reduced when temperatures are low in early spring, autumn acaricide applications were evaluated to control mites as they migrate to their hibernation sites. Post-harvest sulphur and mineral oil treatments were applied in September 2003 and mites were monitored in the following spring. Only the sulphur treated trees were virtually free of blisters. Sulphur treatments showed an efﬁcacy of 95.3% (one application) to 99.6% (three applications), whereas, mineral oil treatments only had an efﬁcacy of 12.8% (one application) to 69.6% (three...

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)...

Avaliação da trofobiose quanto às respostas ecofisiológicas e bioquímicas de couve e pimentão, sob cultivos orgânico e convencional.
Provedor de dados: 21
Autores: Vilanova, Clélio; Silva Júnior, Carlos Dias da.
De acordo com a Teoria da Trofobiose, todo organismo vegetal fica vulnerável à infestação de pragas e doenças quando excessos de aminoácidos livres e açúcares redutores estão presentes no sistema metabólico, provocando condições favoráveis para sua alimentação, maturação e reprodução. Essas condições podem acontecer a partir de quaisquer distúrbios metabólicos causados pelo estresse fisiológico das plantas. A trofobiose está diretamente relacionada ao manejo agroecológico das culturas, contribuindo para a resistência fisiológica vegetal e sustentabilidade do agroecossistema. O objetivo deste estudo foi avaliar a trofobiose em cultivos orgânico e convencional de hortaliças (couve e pimentão), com base na análise de parâmetros bioquímicos (clorofila,...

Avaliação da utilização de Nim (Azadirachta indica) para o controle parasitário em bovinos de produção leiteira em sistema orgânico.
Provedor de dados: 21
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...

Provedor de dados: 21
Autores: Carvalho, Wellington Pereira de; Wanderley, Alberto Luiz.
O presente estudo se propôs a indicar cultivares de feijão (Phaseolus vulgaris) que tenham melhor desempenho no sistema orgânico, além de mostrar que o rendimento ótimo sustentável conseguido pela agricultura orgânica, pode estar muito próximo do rendimento potencial conseguido pela agricultura convencional. No ano de 2003, foram instalados dois ensaios, um irrigado e outro no período das águas, em uma área de pastagem de baixa fertilidade, situação semelhante à encontrada pelos produtores que se iniciam na produção orgânica sem passar pelo período de conversão, utilizando áreas que se encontram em descanso há alguns anos ou pastagens que não receberam aplicações de agrotóxicos ou adubos de alta solubilidade. No ano seguinte, os mesmos ensaios foram...

Avaliação de um modelo de rastreabilidade para produtos orgânicos a partir de certificadoras paranaenses.
Provedor de dados: 21
Autores: Pinheiro, Keren Hapuque; Bittencourt, Juliana Vitória Messias.
A certificação na produção orgânica é um fator fundamental para que o pequeno produtor possa agregar renda aos seus produtos (OLTRAMARI; ZOLDAN; ALTMANN, 2003). No Brasil há em torno de 20.000 estabelecimentos certificados (EPAGRI, 2009) do total de 90.000 unidades orgânicas existentes (IBGE, 2006), este dado pode estar relacionado com alto custo da certificação e o baixo grau de conhecimento técnico dos produtores para seguir as legislações orgânicas vigentes. Tem-se o exemplo da rastreabilidade como um complexo requisito no processo de obtenção da certificação orgânica, portanto, esta pesquisa tem como objetivo verificar a aceitação de um modelo de rastreabilidade para produtos orgânicos, aplicável na pequena propriedade, a partir de conceituadas...

Balanço e análise da sustentabilidade energética na produção orgânica de hortaliças.
Provedor de dados: 21
Autores: Souza, Jacimar Luiz de; Casali, Vicente Wagner D; Santos, Ricardo HS; Cecon, Paulo R.
Os insumos e serviços utilizados na produção vegetal representam custo energético. Dependendo desses fatores e das produtividades obtidas, a conversão da produção em energia determinará a eficiência energética do sistema. A agricultura orgânica somente atingirá a missão de preservação ambiental se tiver comprovada sustentabilidade energética. Neste trabalho, objetivou-se caracterizar os balanços energéticos dos cultivos orgânicos e analisar sua sustentabilidade, em comparação aos sistemas convencionais. Monitoraram-se campos de produção de dez culturas, de 1991 a 2000 em Domingos Martins-ES. Os dados do sistema convencional foram obtidos pelas médias dos coeficientes técnicos da região. Quantificaram-se os coeficientes técnicos, convertendo suas grandezas...

Balanços energéticos agropecuários: uma importante ferramenta como indicativo de sustentabilidade de agroecossistemas.
Provedor de dados: 21
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. Estudos de Balanços Energéticos visam determinar os pontos de estrangulamento energético fundamentando a busca por tecnologias poupadoras de energia,...

Band-steaming reduces laborious hand-weeding in vegetables
Provedor de dados: 21
Autores: Melander, Bo; Jørgensen, Martin H.; Elsgaard, Lars.
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.

Barley undersown with red clover in organic and conventional systems: nitrogen aftereffect on legume growth
Provedor de dados: 21
Autores: Alaru, Marika; Talgre, Liina; Luik, Anne; Tein, Berit; Eremeev, Viacheslav; Loit, Evelin.
Nitrogen (N) deficiency is a major problem in organic and low-input farming systems. Growing spring cereals with  undersown legumes has a positive effect on soil fertility, enriching it with nitrogen, through symbiosis of legumes  with nodule bacteria. Two hypotheses were tested: 1) undersowing of red clover increases the protein content of  barley grains and 2) mineral N has negative aftereffect on growth of legume plants. The aim of this study was to  investigate the effect of organic (cattle manure, off-season cover crop) and mineral N in organic and conventional  farming systems on (i) barley (Hordeum vulgare L.) grain yield and quality, (ii) biomass yield formation of  undersown red clover (Trifolium pratense L.) and (iii) the aftereffect of mineral...

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...

Bathroom transformation: From hygiene to well-being?
Provedor de dados: 21
Autores: Quitzau, M.; Røpke, I.
Western bathroom standards, which have long been dominated by ideas of hygiene, seem to be in the process of change. Whereas transformations of kitchens have been well studied, little attention has been directed towards the contemporary development of bathrooms. This paper provides a case study of the transformation in design, use and meaning of Danish bathrooms, drawing lines back in history but focusing mainly on current changes. The study looks into the continuous development in physical frameworks, practices and images, interpreting the bathroom as a complex arena, where many different forces interact. The empirical basis comprises a combination of statistics, a review of magazine and media coverage, visits to exhibitions, and qualitative interviews....

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...

Bedding hygiene, cleanliness and lying behaviour  for heifers housed on wood chip or straw deep  bedding
Provedor de dados: 21
Autores: Johanssen, Juni Rosann E.; Sørheim, Kristin; Strøm, Turid; Brunberg, Emma.
The aim of this project was to compare the hygienic quality of the bedding, as well as the parasitic load, cleanliness and lying behaviour in heifers kept on either straw or wood chip deep bedding. Fourteen heifers kept in two pens were housed on straw or wood chip bedding for 43 days, after which the bedding material was switched for 43 additional days. Significantly more mould was found in wood chip than in straw and there was a tendency towards less yeast in wood chip. The heifers had a low faecal parasitic load. The results indicate that the wood chip treatment resulted in somewhat cleaner animals. The heifers had a significantly longer total lying time when kept on straw. In conclusion, wood chip deep bedding could be an option as bedding material,...

Beef Cattle Farms’ Conversion to the Organic System. Recommendations for Success in the Face of Future Changes in a Global Context
Provedor de dados: 21
Autores: Escribano, A.J.
Abstract: Dehesa is a remarkable agroforestry system, which needs the implementation of sustainable production systems in order to reduce its deterioration. Moreover, its livestock farms need to adapt to a new global market context. As a response, the organic livestock sector has expanded not only globally but also in the region in search for increased overall sustainability. However, conversions to the organic system have been commonly carried out without analyzing farms’ feasibility to do so. This analysis is necessary before implementing any new production system in order to reduce both the diversity of externalities that the variety of contexts leads to and the vulnerability of the Dehesa ecosystem to small management changes. Within this context and...

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...

Below-ground nitrogen transfer between different grassland species: Direct quantification by 15N leaf feeding compared with indirect dilution of soil 15N
Provedor de dados: 21
Autores: Høgh-Jensen, Dr Henning; Schjoerring, Dr Jan K.
Nitrogen (N) transfer from one species to another is important for the N cycling in low-input grassland. The accuracy of measurements based on indirect dilution of soil 15N has been questioned. In the present work, estimates obtained by this technique were compared with estimates obtained by a direct 15N leaf feeding technique over two complete growing seasons in red clover-ryegrass and white clover-ryegrass mixtures under field conditions.    The direct technique documented that N transfer between clovers and ryegrass is a bi-directional process. The transfer of N from both clovers to ryegrass occurred within 25 days upon the first labelling event. A very high N transfer occurred from white clover to the associated ryegrass, 4.5 and 7.5 g m-2 in the 1st...

Soil degradation in Brazil is a concern due to intensive agricultural production. Combining conservation practice, such as no-tillage, with winter cover crops may increase microbial activity and enhance soil quality more than  either practice alone. This research evaluated the  benefits of long-term (23 years) winter cover crops and reduced tillage on soil microbial quality indicators in an Oxisol from Paraná State, Southern Brazil. The winter cover treatments were: fallow, black oat, wheat, radish, blue lupin, and hairy vetch in conventional (plow) or no-tillage management; the summer crop was a soybean/maize rotation. Soil quality parameters included organic C, microbial biomass C and N, total and labile  polysaccharide, easily extractable and total...

Benzin aus Pflanzen soll das Klima retten
Provedor de dados: 21
Autores: Bär, Markus.
In den Ländern des Nordens wächst die Nachfrage nach Agrodiesel und Ethanol aus Zuckerrohr, Mais oder Getreide. In den USA machen Agrotreibstoffe bereits 5 Prozent des gesamten Treibstoffverbrauchs aus; erklärte Politik ist es, diesen Anteil zu steigern. In der Schweiz gibt es noch keine ausgewachsene Agrotreibstoffindustrie, sondern lediglich Pilotprojekte. Zeit zu fragen, was da auf uns zukommt und wie es um die Ökologie dieser Treibstoffe steht.

Autores: Meyer, Dietmar; Dittrich, Barbara; Köhler, Brigitte; Schmidtke, Knut; Wunderlich, Beate; Lux, Guido; Kolbe, Hartmut.
In diesem Heft der Schriftenreihe des Landesamtes für Umwelt, Landwirtschaft und Geologie sind folgende drei Beiträge enthalten:    Einfluss des Klimawandels auf Humus- und Stickstoffvorräte im Boden sowie Kompensationsmöglichkeiten durch den Ökologischen Landbau. Am Beispiel von drei Agrarstrukturgebieten in Sachsen wurden zunächst mit Hilfe mehrerer Methoden der Humusbilanzierung die Auswirkungen des Klimawandels bis zum Jahr 2050 ermittelt. Die Ergebnisse zeigen, dass die Humusgehalte auf den Diluvial- und Lößböden leicht und den Verwitterungsstandorten der Bergregionen deutlich abnehmen können. Durch verschiedene Formen des ökologischen Landbaus (Ist-Situation, Marktfrucht, Futterbau, organische Düngung, Umwidmung zu Grünland) kann diesem Trend in...

Bewegung bei Betriebsmitteln für den Öko-Landbau?
Provedor de dados: 21
Autores: Speiser, Bernhard.
In der EU-Öko-Verordnung sind, mit Ausnahme der Pflanzenstärkungsmittel, alle als Betriebsmittel zugelassenen Stoffe einzeln aufgeführt.Nicht aufgeführte Stoffe sind verboten. Doch die Landwirtschaft entwickelt sich weiter – und so kommen ständig neue Betriebsmittel hinzu.Wie wird entschieden, ob sie im ökologischen Landbau eingesetzt werden dürfen oder nicht?  Die einer Entscheidung zugrunde liegenden Kriterien sind in Artikel 7 der EU-Öko Verordnung definiert. Allerdings ist ihre Ausfertigung sehr rudimentär, sodass sich die Diskussionen um Neuzulassungen in die Länge ziehen und das System zu erstarren droht. Im EU-Projekt „Organic Inputs Evaluation“ wurden deshalb entsprechende Verbesserungsvorschläge erarbeitet (Speiser, 2005), die in die gerade...

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...

An analysis of peer reviews of 84 organic farming grant applications, submitted to The Swedish Research Council for Environment, Agricultural Sciences and Spatial Planning (FORMAS) in 2001 was carried out to investigate whether peer reviews were influenced by the peer reviewers’ affiliation to organic agriculture research and to what degree peer reviewers distinguish between scientific quality and societal relevance. Fifteen reviewers were grouped in three groups (1) scientists with affiliation to organic farming research, (2) scientists without affiliation to organic farming research and (3) users of the research. The scientist groups assessed societal relevance of the grant applications and scientific quality as a sum of three scientific criteria and the...

Autores: Kerbage, Laurent; Wyss, Gabriela S.; Granado, José; Weibel, Franco; Alföldi, Thomas; Niggli, Urs.
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.

Bio hält das Wasser rein! Eine ökonomische Bewertung
Provedor de dados: 21
Autores: Kratochvil, R.; Lindenthal, T.
Die Biologisch Landwirtschaft leistet aus folgenden Gründen einen wichtigen Beitrag zum Grundund Trinkwasserschutz: Die Beeinträchtigung durch chemisch-synthetische Pflanzenschutzmittel ist ausgeschlossen. Aufgrund des angestrebten geschlossenen Betriebskreislaufes und rechtlicher Vorgaben ist der Eintrag von Nitrat in das Grund- und Trinkwasser drastisch reduziert.  Ökonomische Berechnungen zeigen, dass die Biologische Landwirtschaft zur Verringerung von Kosten, die gegenwärtig die Allgemeinheit tragen muss, beiträgt. Biologischer Landbau bedeutet damit vorsorgenden Grundwasserschutz anstelle nachsorgender Maßnahmen.

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...

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...

N2O is a major greenhouse gas and the majority of anthropogenic N2O emissions originate from agriculturally managed soils. Therefore, developing N2O mitigation strategies is a key challenge for the agricultural sector and biochar soil treatment is one reported option. Biochar's capacity to increase soil pH and to foster activity of specialized N2O reducers has been proposed as possible mechanisms for N2O mitigation. An experiment was undertaken to investigate whether changes in the community composition of N2O reducers was observed under field conditions after biochar application. The study objective was to assess the abundance and taxonomic composition of the functional marker genes nosZ and nosZ –II across a vegetation period of Zea mays L. after biochar...

In this study, we tested the hypothesis that pyrogenic carbon (biochar) has properties that enable  it to replace fresh organic matter (cattle manure) in seedling substrates. These properties include specific  electrophysiological interactions in soil-plant media, stability and longevity. The experiment was conducted in  the nursery at the State University of Mato Grosso, located in the municipality of Nova Xavantina, between April and June 2011. The experimental design consisted of randomized blocks with ten treatments and four replicates, including a commercial substrate. Linear regression analysis showed a strong positive relationship between manure treatments and number of leaves, fresh and dry biomass, diameter, height and Dickson Quality Index at 30...

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...

Biodiversités « utile » et « nuisible » dans les agrosystèmes : importance pour la lutte biologique par conservation
Provedor de dados: 21
Autores: RIS, Nicolas; ION-SCOTTA, Michela; AL KHATIB, Fadel; Lambion, Jérôme; Warlop, Francois; Bout, Alexandre.
La lutte biologique par conservation repose sur la mise en place d’aménagements dans ou  autour de parcelles cultivées ou de modifications des pratiques culturales de façon à favoriser  la régulation des ravageurs des cultures par des auxiliaires de lutte biologiques indigènes.  Pour être efficaces, les méthodes de lutte biologique par conservation nécessitent toutefois  plusieurs pré-requis : (i) une bonne compréhension de la biodiversité associée aux  agrosystèmes, (ii) l’optimisation des échanges entre la culture et les autres composantes de  l’agrosystème, (iii) la prise en compte d’éventuels effets non-intentionnels associés aux  auxiliaires favorisés. Ces trois points sont discutés dans le cadre d’un programme en cours  dont l’objectif est d’évaluer...

Autores: Birrer, Simon; Zellweger-Fischer, Judith; Stoeckli, Sibylle; Korner-Nievergelt, Fränzi; Balmer, Oliver; Jenny, Markus; Pfiffner, Lukas.
Farmland biodiversity has often been assessed, but seldom at the farm scale, although it is ultimately the farm level at which decisions are taken. Therefore, a credit point system (CPS) was developed based on 32 options known to enhance farmland biodiversity. It was verified whether the resulting CPS score and farm-scale biodiversity are correlated considering four indicator groups (plants, grasshoppers, butterflies and birds) on 133 farms in the Swiss lowland. We further compared the suitability of the CPS score in reflecting farm-scale biodiversity to three alternative habitat measures, i.e. the amount of ecological compensation areas (ECAs, i.e. agri-environment scheme options), ECAs with a high ecological quality and valuable semi-natural elements...

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).

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,...

In the framework of the European project BIOBIO, we compared between countries habitat and cumulated species richnesses of plants, wild bees, spiders and earthworms, measured in 169 conventional and organic farms belonging to 10 case studies in 10 European countries. For the French case study (Gascony Valleys and Hills), correlations between direct (habitat and taxonomic richnesses) and indirect (agricultural practices) indicators of biodiversity within 8 conventional and 8 organic farms, were calculated. Results showed that the main driver of biodiversity at the farm level was the number of cultivated and above all semi-natural habitats, inthe French case study region as well as inthe other regions. This factor partially explained the highest biodiversity...

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...

Biodynamic Agriculture: The Journey from Koberwitz to the World, 1924-1938
Provedor de dados: 21
Autores: Paull, John.
In the last year of his life, the Austrian philosopher Rudolf Steiner challenged the direction and practice of contemporary agriculture. This was an early response to the proliferation of chemical agriculture. Steiner laid the foundation for an alternative agriculture, one that would ‘heal the earth’, in the agriculture course, a series of eight lectures at Koberwitz (now Kobierzyce, Poland) in 1924. Steiner set in train a process that led to the development, articulation, and naming of biodynamic agriculture, culminating in the publication of 'Bio-Dynamic Farming and Gardening' by Ehrenfried Pfeiffer in 1938. Pfeiffer's book appeared in Dutch, English, French, German, and Italian, and fulfilled Steiner's injunction to bring his agricultural lecture course...

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...

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...

Bioethanol production by inherent enzymes from rye and  wheat with addition of organic farming cheese whey
Provedor de dados: 21
Autores: Kádár, Zsófia; Christensen, Anne Deen; Thomsen, Mette Hedegaard; Bjerre, Anne Belinda.
In organic farming, there is a strong effort to minimize  the share of non-renewable resources (e.g. fossil fuels) and use only (preferably on-farm produced) bio-based energy and renewable raw materials, with the aim of achieving sustainable production systems and to become self-sufficient in energy.   Throughout our studies, wheat and rye grain was used as raw material in bioethanol production with the purpose of producing in situ enzymes (during germination) for the hydrolysis of starch in the grains and compared with commercial amylase enzyme preparations. Whey permeate was incorporated into the grain in Simultaneous Saccharification and Fermentation (SSF) process to use a cheap nutrient and water source. The ethanol fermentations were completed by 190...

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...

Biogas and ethanol potentials in selected biomasses for  organic farming
Provedor de dados: 21
Autores: Oleskowicz-Popiel, Piotr; Nielsen, Henrik Bangsø; Thomsen, Anne Belinda; Schmidt, Jens Ejbye.
The production of bioenergy in organic agriculture (OA) can reduce its dependency on fossil fuels and decrease greenhouse‐gases (GHG) emissions; consequently increasing the sustainability of organic farming. Different biomasses were characterized biologically and chemically for their biogas and bioethanol potential at organic farms in Denmark. Batch experiments indicated methane yield [GJ/ha]: 260.7 (fresh maize), 272.7 (maize silage), 127.1 (fresh rye), 169.7 (rye silage), 161.7 (dried rye), 110.5 (fresh clover), 117.8 (clover silage), 72.3 (dried clover), and 41.1 (dried vetch). Theoretical ethanol yield [GJ/ha] showed: 119.8 (fresh maize), 109.2 (maize silage), 36.9 (fresh rye), 39.9 (rye silage), 84.7 (dried rye), 28.9 (fresh clover), 24.4 (clover...

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...

Provedor de dados: 21
Autores: Santamaria-Fernandez, Maria; Molinuevo-Salces, Beatriz; Lübeck, Mette; Uellendahl, Hinrich.
The biogas potential of the residual fractions of four organically grown green crops after protein extraction was studied. The protein extraction method involved screw pressing of freshly harvested biomass to obtain a plant juice, followed by precipitation of the proteins. After protein extraction, 95% of organic matter was still present in the residual press cake and juice. Methane yields in the range of 219–375 and 429–539 ml-CH4 g-VS−1 were obtained for the mono-digestion of press cake and the residual juice, respectively, and up to 81% of the methane potential of the fresh crops was recovered in the two residual fractions when evaluated separately.

Die Verbesserung der Lebensqualität und des Einkommens der Landbevölkerung in Entwicklungsländern setzt deshalb eine Verbesserung der Absatzmöglichkeiten lokaler Agrarerzeugnisse und eine Entwicklung der Subsistenzhin zu einer Marktproduktion voraus. Die große Herausforderung für die Entwicklungszusammenarbeit ist es, den Bauern Wege für eine Verbesserung ihrer Anbaumethoden aufzuzeigen, damit sie von den Marktchancen profitieren können – ohne ihre wirtschaftliche Situation zu verschlechtern, ohne neue Abhängigkeiten zu schaffen und ohne die natürlichen Ressourcen zu beeinträchtigen.    Dieser Herausforderung muss sich auch der Bio-Landbau stellen.Wie kann er in ärmeren Ländern zu...

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...

Biological control of common bunt (Tilletia tritici) in organic farming
Provedor de dados: 21
Autores: Borgen, Anders; Davanlou, Mehrnaz.
Common bunt (Tilletia tritici syn. T. caries) is a significant seed borne plant disease in organic agriculture. General measures in ecological crop protection like crop rotation and manuring practice has in practice failed to control this disease, and direct seed treatment therefore seems to be necessary to ensure yield and food quality. Current study indicate that biological control can give successful control without negative effects on seed germination vigour. A combination of biocontrol agents and milk powder improves the effect of the biocontrol. Application of compost to the soil increases the frequency of this disease. The potential role of biocontrol within the principles of ecological disease management is being discussed.

Biological nitrogen fixation and nitrogen and phosphorus budgets in farmer-managed intercrops of maize-pigeonpea in semi-arid southern and eastern Africa
Provedor de dados: 21
Autores: Adu-Gyamfi, J. J.; Myaka, F.A.; Sakala, W.D.; Odgaard, R.; Vesterager, J. M.; Høgh-Jensen, Henning.
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...

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...

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...

Biologische Helminthenkontrolle bei Weidetieren mit nematophagen Pilzen
Provedor de dados: 21
Autores: Hertzberg, Hubertus; Larsen, Michael; Maurer, Veronika.
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....

Biomass energy in organic farming - the potential role of short rotattion coppice
Provedor de dados: 21
Autores: Jørgensen, Uffe; Dalgaard, Tommy; Kristensen, Erik Steen.
One of the aims of organic farming is to “reduce the use of non-renewable resources (e.g. fossil fuels) to a minimum”. So far, however, only very little progress has been made to introduce renewable energy in organic farming. This paper presents energy balances of Danish organic farming compared with energy balances of conventional farming. In general, the conversion to organic farming leads to a lower energy use (approximately 10% per unit of product). But the production of energy in organic farming is very low compared with the extensive utilisation of straw from conventional farming in Denmark (energy content of straw used for energy production was equivalent to 18% of total energy input in Danish agriculture in 1996).    Biomass is a key energy carrier...

Biomass of weeds, crops and arthropods in conventional and organic cereal fields
Provedor de dados: 21
Autores: Bruus Pedersen, Marianne; Axelsen, Jørgen Aagaard; Tybirk, Knud.
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.

Biomass production, symbiotic nitrogen fixation and inorganic N use in dual and tri-component annual intercrops
Provedor de dados: 21
Autores: Andersen, Mette Klindt; Hauggaard-Nielsen, Henrik; Ambus, Per; Jensen, Erik Steen.
The interspecific complementary and competitive interactions between pea (Pisum sativum L.), barley (Hordeum vulgare L.) and oilseed rape (Brassica napus L.), grown as dual and tri-component intercrops were assessed in a field study in Denmark. Total biomass production and N use at two levels of N fertilisation (0.5 and 4.0 g N/m2), were measured at five harvests throughout a growing season. All intercrops displayed land equivalent ratio values close to or exceeding unity, indicating complementary use of growth resources. Whereas both rape and barley responded positively to increased N fertilisation, irrespective of whether they were grown as sole- or intercrops, pea was strongly suppressed when grown in intercrop. Of the three crops barley was the...

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.

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.

Bio-Weide-Beef – mehr Absatz für Biofleisch
Provedor de dados: 21
Autores: Meili, Eric; Kessler, Hans-Georg.
Die Migros will ihr Bio-Weide-Beef-Programm von 45 auf 90 Tiere pro Woche ausdehnen. Damit steht Biofleischproduzentinnen und -produzenten eine wirtschaftliche Alternative zur Produktion von Knospe-Bankvieh offen. Für Knospe-Bankvieh bestand bisher nur eine beschränkte Nachfrage zu wenig interessanten Preisen. Der Moment ist günstig, ins Bio-Weide-Beef-Programm einzusteigen, sei es zur Produktion von Mastremonten oder von schlachtreifen Bio-Weide-Beef-Tieren.

Biozucht soll dem Standort gerecht werden
Provedor de dados: 21
Autores: Zeltner, Esther.
Wer Biozucht betreibt, züchtet auch standortgerecht. In der Theorie ist dieses Ziel den meisten klar, doch in der Praxis züchten viele Biomilchviehhalter nach wie vor auf milchbetonte Tiere, auch wenn sie gar nicht zum Hof passen. Nach den Gründen suchte ein Seminar für biologische Braunviehzucht am Plantahof.

Birch tar oil is an effective mollusc repellent: field and laboratory experiments using Arianta arbustorum (Gastropoda: Helicidae) and Arion lusitanicus (Gastropoda: Arionidae)
Provedor de dados: 21
Autores: Lindqvist, Isa; Lindqvist, Bengt; Tiilikkala, Kari; Hagner, Marleena; Penttinen, Olli-Pekka; Pasanen, Tiina; Setälä, Heikki.
Populations of two molluscs, the land snail Arianta arbustorum and the Iberian slug Arion lusitanicus, have increased substantially in many places in the northern Fennoscandia in recent years. This has resulted in considerable aesthetic and economic damage to plants in home gardens and commercial nurseries. Birch tar oil (BTO), is a new biological plant protection product, and was tested against these molluscs. In this study we examined whether 2 types of BTO, used either alone, mixed together, or mixed with Vaseline®, could be applied as 1) a biological plant protection product for the control of land snails by direct topical spray application, 2) as a repellent against snails when painted on a Perspex® fence, and 3) as a repellent against slugs when...

Birnenpockenmilbe: Nacherntebehandlung mit Schwefel
Provedor de dados: 21
Autores: Höhn, Heinrich; Linder, Christian; Daniel, Claudia; Wyss, Eric.
Die verschiedenen Exakt- und Praxisversuche sowie die ersten Erfahrungen von Praxisanwendungen zeigen, dass mit einer Nacherntebehandlung mit 2% Schwefel (entspricht 32 kg/ha bei einem Baumvolumen von 10 000 m3/ha) eine erfolgreiche Bekämpfungsmöglichkeit gegen Birnpockenmilben vorliegt. Raubmilben werden nach unserer Erfahrung kaum beeinflusst, da sie zu diesem Zeitpunkt bereits weitgehend die Winterquartiere bezogen haben. Auch andere negative Auswirkungen konnten wir bis jetzt nicht feststellen. Unter Berücksichtigung aller bisher bekannten Fakten muss in Zukunft für die Birnpockenmilbenbekämpfung bevorzugt die neu bewilligte Herbstbehandlung mit Schwefel empfohlen werden.

Black polyethylene mulch is used for weed control in a range of crops under the organic system. The use of black polypropylene mulch is usually restricted to perennial crops. The trial was conducted at Experimental station of Department of Crop Production of the Czech University of Life Science Prague-Uhříněves in Czech Republic. For the experiments were used black polypropylene woven mulch (comparison wit bare soil), two varieties of early potatoes Finka and Katka. Black polypropylene textile was used in potatoes by organic agriculture and it had positive effect on soil temperature (in the depth of 100 mm). Slightly higher soil temperatures under black polypropylene mulch in the vegetation period after planting had favourable influence on earlier stands...

Autores: Schleuß, Uwe.
Bodenbearbeitung und Unkrautregulierung gehören unter den Produktionsbedingungen des ökologischen Landbaus  zu den wichtigsten Maßnahmen, um Erträge zu steigern und zu sichern. Die Unkrautregulierung muss sinnvoll in die pflanzenbaulichen Maßnahmen eingebunden sein, wobei Art und Zeitpunkt der Bodenbearbeitung, Feldhygiene, Zwischenfruchtanbau, Fruchtfolge und Bestandesführung als indirekte Maßnahmen besonders wichtig sind. Verschiedene neuere landtechnische Entwicklungen auf dem Gebiet der Unkrautregulierung können zu deutlichen Produktionsfortschritten beitragen, wobei folgende Anforderungen zu stellen sind: zweckmäßiger Bekämpfungserfolg, hohe Schlagkraft, Reduzierung der Handarbeit, Bodenschonung, ökologische Verträglichkeit, geringer Energieverbrauch...

Autores: Mäder, Dr. Paul; Fliessbach, Dr. Andreas; Dubois, Dr. David; Gunst, Lucie; Fried, Dr. Padruot; Niggli, Dr. Urs.
Um die Effektivität landwirtschaftlicher Anbausysteme zu beurteilen, bedarf es eines Verständnisses der Agrarökosysteme. Eine 21-jährige Studie ergab 20 Prozent geringere Erträge bei ökologischen Anbausystemen gegenüber konventionellen, obgleich der Einsatz von Düngemitteln und Energie um 34 bis 53 Prozent und der von Pestiziden um 97 Prozent geringer war. Wahrscheinlich führen die erhöhte Bodenfruchtbarkeit und die größere biologische Vielfalt in den ökologischen Versuchsparzellen dazu, dass diese Systeme weniger auf Zufuhr von außen angewiesen sind.

Hydrokultur führt bei Bohnen zu höheren Erträgen, ist aber gleichzeitig qualitätsmindernd. Demeter-Saatgut und konventionelles Saatgut wurden jeweils biologisch-dynamisch und in Hydrokultur angebaut.  Die vorliegenden Ergebnisse legen nahe, dass es auch im Pflanzenbau mehr oder weniger artgemäße Anbaubedingungen gibt. Der biodynamische Anbau in Erde erscheint gegenüber der Hydrokultur als weitaus artgemäßer.   Nicht artgemäßer Pflanzenanbau von weißen Bohnen in Hydrokultur prägt sich im Samen ab und lässt sich mit der hier angewendeten empfindlichen Lumineszens-Anregungs-Spektroskopie physikalisch messen und statistisch signifikant von eher artgemäßem biologisch-dynamischen Anbau in Erde unterscheiden.

Kan og vil landbruget bidrage til reduktion af drivhusgasser? Undersøgelser tyder på, at der i landbrugssektoren findes et stort og uudnyttet potentiale for relativt billig reduktion af drivhusgasser. Selvom måling af reduktion i udledning af drivhusgasser inden for landbrugssektoren er behæftet med omfattende usikkerhed, vil man ved at måle reduktion indirekte gennem relative ændringer i produktionsprocesser kunne inkludere landbrugssektoren i reguleringsordninger. Spørgsmålet er, hvordan man kan få landbruget til at bidrage? Vi overvejer brugen af standarder, grønne afgifter og omsættelige kvoter. Vi finder, at landbrugssektoren vil have en ikke ubetydelig interesse i at få tildelt kvoter og deltage i det europæiske kvotesystem, EU ETS. Landbrugets...

May 2006. 380 pages, £55, ISBN 1 84593 078 9.    Global Development of Organic Agriculture is valuable for its both explicit and implicit championing of the diversity of organic agriculture systems - and in particular, its acknowledgment of the legitimacy and value of both certified and non-certified organics. In this, it serves as a useful foil to the fortress organics mentality that sees non-certified organics as some kind of impostor or threat to “the brand”. This book takes as a starting premise the legitimacy and value of both strands of organics, and proceeds...

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...

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...

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...

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...

Breslau (Wrocław): In the footsteps of Rudolf Steiner
Provedor de dados: 21
Autores: Paull, John.
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.

To determine if present commercial broccoli cultivars meet the diverse needs of organic management systems, such as adaptation to low N input, mechanical weed management, and no chemical pesticide use, and to propose the selection environments for crop improvement for organic production, we compared horticultural trait performance of 23 broccoli cultivars (G) under two management (M) systems (organic and conventional) in two regions of the United States (Oregon and Maine), including spring and fall trials. In our trials, location and season had the largest effect on broccoli head weight, with Oregon outperforming Maine, and fall trials outperforming spring plantings.

Broilers reduce the apple sawfly population in organic apple growing
Provedor de dados: 21
Autores: Lindhard Pedersen, Hanne; Olsen, A.; Korsgaard, Maren; Pedersen, Birgitte.
In organic production in Denmark, no pesticides are allowed. The need for alternative pest control is therefore large. Apple sawfly (Hoplocampa testudinea) cause big crop losses in apples. Sawflies infest fruitlets and cause these to drop prematurely after which the pests pupate in the topsoil.    Combined production of hens and fruit trees is a subject often discussed in organic fruit production in Denmark. The feeding poultry may reduce the population of pests, which stay in the soil as a part of their life circle. Yet, very little research has been carried out on this type of production system.

ANOVA-modelling showed a significant response of bryophyte species richness to fertilisation (negative) and defoliation (positive). Species composition of vascular vegetation had no effect on bryophyte richness, but a significant negative relationship was found between vascular plant biomass and species richness of bryophytes. Vascular plant dry weight above 400 g m-2 appeared fatal to bryophytes. At high nutrient levels, bryophytes extinction seemed to be...

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,...

Autores: Niggli, Urs; Andres, Christian; Willer, Helga; Baker, Brian P.
Organic food and farming systems have a great untapped potential to provide the world with healthy, high-quality food that is produced and distributed in an ecologically sound and fair way, but numerous production challenges and barriers slow the adoption of organic practices. Innovations addressing these challenges are not being developed sufficiently because of insufficient capacity in research, development and technologytransfer, especiallyinAfrica, Asia and Latin America. Given the limited resources, as well as the specific needs of organic food and farming systems, different pathways are needed to develop new technologies that are compatible with the principles of organic farming. The Technology Innovation Platform of IFOAM...

Building Resilience through Farmers’ Experiments in Organic Agriculture: Examples from Eastern Austria
Provedor de dados: 21
Autores: Kummer, Susanne; Milestad, Rebecka; Leitgeb, Friedrich; Vogl, Christian R.
Farmers have always lived in changing environments where uncertainty and disturbances are inevitable. Therefore, farmers need the ability to adapt to change in order to be able to maintain their farms. Experimentation is one way for farmers to learn and adapt, and may be a tool to build farm resilience. Farmers’ experiments, as defined in this paper, are activities where something totally or partially new is introduced at the farm and the feasibility of this introduction is evaluated. The theoretical framework applied to study farmers’ experiments is the concept of resilience. Resilience is the capacity of social-ecological systems to cope with change, and is a framework used to assess complex systems of interactions between humans and ecosystems.  This...

Buying Eco-Labelled Produce? Knowledge of Production Standards, Trust in Labels and Organic Consumption
Provedor de dados: 21
Autores: Daugbjerg, Carsten; Smed, Sinne; Andersen, Laura Mørch; Schvartzman, Yonatan.
Eco-labels have an import role in promoting green  consumption. Most eco-labelled products are credence products. The valued process attributes they contain are not observable characteristics even after purchase or consumption and therefore the consumers rely heavily on eco-labels as a guarantee that these attributes are actually delivered when the product is purchased and consumed. However, the label will only have the desired effect if the consumers know the production standards underpinning it and have trust in the label. We test this hypothesis using organic food as our example. The empirical results obtained on the basis of our analysis of detailed survey data from Denmark show that the higher the level of knowledge of labelling attributes, the more...

The turnover of native and applied C and N in undisturbed soil samples of different texture but similar mineralogical composition, origin and cropping history was evaluated at –10 kPa water potential. Cores of structurally intact soil with 108, 224 and 337 g clay kg-1 were horizontially sliced and 15N-labelled sheep faeces was placed between the two halves of the intact core. The cores together with unamended treatments were incubated in the dark at 20°C and the evolution of CO2-C determined continuously for 177 d. Inorganic and microbial biomass N and 15N were determined periodically. Net nitrification was less in soil amended with faeces compared with unamended soil. When adjusted for the NO3-N present in soil before faeces was applied, net nitrification...

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,...

Autores: Kymäläinen, Hanna-Riitta; Sjöberg, Anna-Maija.
The aim of this study was to screen the cadmium (Cd) contents of seed and seed crush of Finnish linseed and to evaluate the acceptable daily dose. The Cd content of Finnish linseed is of interest, since some properties of linseed as the content of fatty acids are different in northern growth locations compared with other growing areas. Seed samples (N = 85) were collected from the experimental farm of Helsinki University and from commercial fields in different locations in southern Finland and Ostrobothnia. In addition, 15 samples of linseed crush were examined. The cadmium contents of the linseed samples, determined with atomic absorption spectroscopy, varied between 0.27 and 1.3 mg kg-1 (dry weight) (mean 0.61 mg kg-1). The Cd contents of the crush...

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...

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.

Can grasslands enhance the ecological service of pollinators? Effects of number of cuttings on availability of floral resources for flower-visiting insects
Provedor de dados: 21
Autores: Dupont, Y.; Strandberg, B.; Bang Madsen, H.; Bygebjerg, R.
Bees and other flower-visiting insects are experiencing periods of food shortage, particularly in intensively managed agricultural landscapes in Europe. As part of the Danish project EcoServe (http://agro.au.dk/ecoserve/ ) we therefore investigated whether increased richness of selected herbaceous species in organic hay fields acted as a floral resource thus enhancing abundance and biodiversity of pollinators. Moreover, we investigated if availability of floral resources was affected by cutting regime (timing and number of cuttings during the growing season) in 11 herbaceous species, which are often used in grassland seed mixtures.    In a field survey, we visited 20 organic hay meadows of different age (3-100 years), and conducted surveys regularly...

Autores: Xie, Yue; Tittarelli, Fabio; von Fragstein, Peter; Bavec, Martina; Canali, Stefano; Kristensen, Hanne Lakkenborg.
The effect of introduction strategy for living mulches (LMs) to reduce the potential nitrate leaching was investigated when grown with vegetables with high nitrogen (N) demand and low use efficiency in four European countries: Italy, Slovenia, Germany and Denmark over 2 yr. The plant N uptake and soil nitrate N content at harvest, in the autumn, and in the following spring were measured below open-pollinated and hybrid cultivars of cauliflower and leek crops. The cultivars performed differently over the 2 yr. In Italy and Slovenia, when LM of burr medic or white clover was broad sown (addition design ADD) at the same time as crop transplanting, the N uptake of crops was hampered without increasing the total aboveground N accumulation. Delaying LM sowing by...

Can N Use and Farm Income be Optimized for Organic Field Vegetable Rotations in Europe?
Provedor de dados: 21
Autores: Schmutz, Ulrich; Firth, Chris; Rayns, Francis; Rahn, Clive.
Most fresh organic vegetables are produced in intensive rotations, which rely heavily on large inputs of nitrogen to maintain the yield and quality of produce demanded by customers. Field vegetable crops often use nitrogen inefficiently and may leave large residues of nitrogen in the soil after harvest, which can lead to damage to soil, water and air quality. The four-year project EU-ROTATE_N "Development of a model-based decision support system to optimize nitrogen use in horticultural crops rotations across Europe" aims to reduce some of these problems. The project, led by HRI Wellesbourne, started in January 2003 and involves seven research organizations from countries in northern, central and southern Europe. Work includes the evaluation of the effects...

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: 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...

Caratteristiche agronomiche e possibilità di utilizzo di Brassica juncea (L.) Czern
Provedor de dados: 21
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...

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...

Carbohydrates in hot water extracts of soil aggregates as affected by long-term management
Provedor de dados: 21
Autores: Debosz, K.; Vognsen, L.; Laborioau, R.
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...

Carbon footprints of crops from organic and conventional arable crop rotations – using a life cycle assessment approach
Provedor de dados: 21
Autores: Knudsen, Marie Trydeman; Meyer-Aurich, Andreas; Olesen, Jørgen E.; Chirinda, N.; Hermansen, J.E.
Many current organic arable agriculture systems are challenged by a dependency on imported livestock manure from conventional agriculture. At the same time organic agriculture aims at being climate friendly. A life cycle assessment is used in this paper to compare the carbon footprints of different organic arable crop rotations with different sources of N supply. Data from long-term field experiments at three different locations in Denmark were used to analyse three different organic cropping systems (‘Slurry’, ‘Biogas’ and ‘Mulching’), one conventional cropping system (‘Conventional’) and a “No input” system as reference systems. The ‘Slurry’ and ‘Conventional’ rotations received slurry and mineral fertilizer, respectively, whereas the ‘No input’ was...

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...

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...

Carbon sequestration potential of organic agriculture in northern Europe - a modelling approach
Provedor de dados: 21
Autores: Foereid, Bente; Høgh-Jensen, Henning.
Decline in carbon content in agricultural soils contributes both to climate change and to soil fertility problems. The CENTURY element dynamics simulation model was tested and adapted for Northern European agricultural conditions using long-term datasets from Askov experimental farm in southern Denmark. The part of the model dealing with decomposition was tested in isolation using a bare fallow experiment and it could predict soil organic matter levels with high accuracy. In the cropping experiments predictions were less accurate. The crop production was not accurately predicted. Predictions were more accurate on loamy than on sandy soils. The model was used to predict the effect of conversion to organic agriculture on carbon sequestration as soil organic...

Carbon stocks, litterfall and pruning residues in monoculture and agroforestry cacao production systems
Provedor de dados: 21
Autores: Schneidewind, Ulf; Niether, Wiebke; Armengot, Laura; Schneider, Monika; Sauer, Daniela; Heitkamp, Felix; Gerold, Gerhard.
Agroforestry systems (AFS) can serve to decrease ecosystem carbon (C) losses caused by deforestation and inadequate soil management. Because of their shade tolerance, cacao plants are suitable to be grown in AFS, since they can be combined with other kinds of trees and shrubs. The potential for C sequestration in cacao farming systems depends on various factors, such as management practices, stand structure and plantation age. We compared conventionally and organically managed cacao monoculture systems (MCS) and AFS in Sara Ana (Bolivia) with respect to C stocks in plant biomass and to amounts of litterfall and pruning residues. The total aboveground C stocks of the AFS (26 Mg C ha−1) considerably exceeded those of the MCS (~7 Mg C ha−1), although the...

Carbon stocks, tree diversity, and the role of organic  certification in different cocoa production systems in Alto  Beni, Bolivia
Provedor de dados: 21
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...

Carotenoids are one of the major food micronutrients in  human diets and the overall objective of this review is to re-examine the role of carotenoids in human nutrition. We have emphasized the attention on the following carotenoids present in food and human tissues: β-carotene, β-cryptoxanthin, -carotene, lycopene, lutein and zeaxanthin; we have reported the major food sources and dietary intake of these compounds. We have tried to summarize positive and negative effects of food processing, storage, cooking on carotenoid content and carotenoid bioavailability. In particular, we have evidenced the possibility to improve carotenoids bioavailability in accordance with changes and variations of technology procedures.

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....

Catch crop strategy and nitrate leaching following a grazed grass-clover
Provedor de dados: 21
Autores: Hansen, E.M.; Eriksen, J.; Vinther, F.P.
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.

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...

Catch crops have little effect on P and K availability of depleted soils
Provedor de dados: 21
Autores: Jensen, Lars Stoumann; Pedersen, Anders; Magid, Jakob; Nielsen, Niels Erik.
It is a well-known fact that catch crops have a significant effect on availability and loss of soil inorganic nitrogen (Thorup-Kristensen et al., 2003) and recently marked effects on soil inorganic sulphur dynamics have also been shown (Eriksen and Thorup-Kristensen 2002; Eriksen et al., 2004).    However, we know much less about the effect of catch crops on phosphorous (P) and potassium (K) mobilisation and availability for the next crop. After several years of organic cash crop production, e.g. vegetables and cereals, yield levels may gradually be limited by soil P and K availability, depending on the initial status at conversion to organic production principles. This is particularly the case during the establishment phase of certain vegetable cultures...

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...

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...

Cats and Goat Whey Associated with Toxoplasma gondii Infection in Pigs
Provedor de dados: 21
Autores: Meerburg, B.G.; Van Riel, J.W.; Cornelissen, J.B.; Kijlstra, A.; Mul, M.F.
In organic livestock production systems, farm-management factors are thought to play an important role in the on-farm prevalence of Toxoplasma gondii. Serological results and the results of an HACCP analysis were combined to determine important risk factors for the prevalence of this protozoan parasite. Mathematical analysis demonstrated that feeding goat whey to pigs and the presence of a high number of cats were positively correlated to T. gondii seroprevalence in pigs. Not covering roughage and the farmers' assumption that pigs can come into contact with cat feces also showed a positive relationship. In order to decrease the risk of T. gondii infecting their pigs, farmers should limit the access and number of cats on their farms and refrain from feeding...

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...

Certification of organic mass catering - a need for harmonization across Europe?
Provedor de dados: 21
Autores: Lukas, Melanie; Strassner, Carola; Løes, Anne-Kristin.
To evaluate the state of the art of organic certification in out-of-home catering, a survey was carried  out among relevant stakeholders in several European countries. The Council Regulation (EC) No  834/2007 about organic production specifically excludes what is called mass catering. Hence, a range  of diverging systems for certification of organic catering and restaurants have been developed. This  study presents opinions about a potential EU-wide harmonisation of an organic certification scheme  for mass catering from relevant stakeholders. Certification bodies and other public authorities as well  as stakeholders close to the catering practice were generally positive towards the idea of a  harmonisation process. Several stakeholders should be involved...

Certified organic agriculture in China and Brazil: Market accessibility and outcomes following adoption
Provedor de dados: 21
Autores: Oelofse, Myles; Høgh-Jensen, Henning; Abreu, L.S.; Almeida, Gustavo Fonseca de; Hui, Qiao Yu; Sultan, Tursinbek; de Neergaard, Andreas.
Based on three case studies in China and Brazil, this paper explores the terms of access for farmers' participation in certified organic agriculture (OA) and investigates the influence of adoption on productivity, nutrient budgets, income and labour use. Small-scale farmers converting to OA require substantial external production-related, marketing and certification support. Access to OA was strongly dependent upon the type of support available to farmers. Organization based on a contract-farming model resulted in OA only being an option available to a narrow group of farmers, whilst OA initiated by a farmer cooperative provided better access. Gross output was significantly higher for oranges, whilst for the other crops gross output was similar. However,...

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...

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...

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...

Changes in the nutrient content of agricultural soil on conversion to organic farming, in relation to farm level nutrient balances and soil contents of clay and organic matter.
Provedor de dados: 21
Autores: Løes, Anne-Kristin; Øgaard, Anne Falk.
Agricultural soil on 12 farms converting to organic farming was sampled in 1989 and 1995 at the same sample points. Concentrations of plant-available (-AL) P, K, Ca and Mg, HNO3-soluble K, tot- N, tot-C and pH were measured in two layers. The average K-AL concentration and pH were reduced in both layers. The average P-AL concentration was reduced in the topsoil. K-AL and P-AL increased in samples with low concentrations and decreased in samples with high and very high concentrations in 1989. The total N concentration increased in the subsoil. Tot-N and tot-C increased in top- and subsoil with a low organic matter content. The net import of P, calculated by farm level nutrient balances, was negatively correlated to the change in kg P-AL per hectare in 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...

Autores: Roepstorff, Allan; Mejer, Helena; Thomsen, Lisbeth E.; Thamsborg, Stig M.; Byrne, Derek V.; Hansen, Laurits L.; Bach Knudsen, Knud Erik; Møller, Kristian.
The carbohydrate inulin is known to reduce the production of skatole in pigs. This is caused by inulin changing the intestinal flora, so that the bacteria that produce skatole are held in check. This change in intestinal flora also reduces the number of intestinal parasites in the pigs. However the high cost of inulin makes its use in pig feed impractical.    Chicory root contains inulin and a series of other carbohydrates and secondary metabolites. Therefore we have examined whether chicory root can replace pure inulin and thereby reduce boar taint, improve the taste of pork and reduce the infection of pigs with pathogenic parasites and bacteria.

Autores: Paull, John.
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...

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...

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...

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...

Cikorierødder forbedrer smag og lugt i økologisk svinekød

Sukkerstoffet inulin er kendt for at kunne nedsætte dannelsen af skatol hos svin. Det skyldes at inulin ændrer tarmfloraen, så bakterier der danner skatol bliver holdt i skak. Samtidig bevirker den ændrede tarmflora at grisene får færre indvoldsorm. Inulin er imidlertid for dyrt til, at det kan betale sig at bruge det i svinefoder.    Cikorierødder indeholder inulin og en række andre kulhydrater plus sekundære metabolitter. Derfor har vi undersøgt om cikorierødder kan erstatte ren inulin og derigennem mindske ornelugten, forbedre smagen og nedsætte grisenes smitte med sygdomsfremkaldende parasitter og bakterier.

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...

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 =...

Clay dispersibility and soil friability – testing the soil clay-to-carbon saturation concept
Provedor de dados: 21
Autores: Schjønning, P.; de Jonge, L.W.; Munkholm, L.J.; Moldrup, P.; Christensen, B.T.; Olesen, J.E.
Soil organic carbon (OC) influences clay dispersibility, which affects soil tilth conditions and the risk of vertical migration of clay colloids. No universal lower threshold of OC has been identified for satisfactory stabilization of soil structure. We tested the concept of  clay saturation with OC as a predictor of clay dispersibility and soil friability. Soil was sampled three years in a field varying in clay content (~100 to ~220 g kg-1 soil) and grown with different crop rotations. Clay dispersibility was measured after end-over-end shaking of field-moist soil and 1-2 mm sized aggregates either air-dried or rewetted to -100 hPa matric potential. Tensile strength of 1-2, 2-4, 4-8 and 8-16 mm air-dried aggregates was calculated from their compressive...

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. The...

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)...

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...

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...

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.

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...

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...

Cocoa and total system yields of organic and conventional agroforestry vs. monoculture systems in a long-term field trial in Bolivia
Provedor de dados: 21
Autores: Schneider, M.; Andres, C.; Trujillo, G.; Alcon, F.; Amurrios, P.; Perez, E.; Weibel, F.; Milz, J.
Cocoa (Theobroma cacao L.) is produced in systems of varying complexity ranging from monoculture with temporary shade to highly diverse agroforests. Producers have to weigh high cocoa yields in the short to medium term in monocultures against higher total system yields in the short term and sustainable production systems in the long term in conjunction with ecosystem services in agroforestry systems (AFs). More long-term data on the comparative agronomic, economic and ecological performance of differently managed cocoa production systems is required to make sound recommendations to farmers. This paper describes the only long-term field trial worldwide comparing different cocoa production systems under conventional and organic management. The factors (i)...

Co-designing innovative cropping systems to improve soil functioning in organic farming
Provedor de dados: 21
Autores: Lefèvre, Vincent; Capitaine, Mathieu; Peigne, Joséphine; Roger-Estrade, Jean.
Organic agriculture is called upon to raise production to meet growing demand all the while ensuring the respect of the environment. In this context, improving the soil biological activity is crucial. Farmers are taking great interest in agroecological practices, such as conservation tillage associated with soil cover crops. The inclusion of these practices into current organic crop management systems calls for profound changes in the whole system.In this paper, we present aeight steps method to help farmers designing innovative prototypes of cropping systems. The method involves three design workshops, starting with a given decontextualized situation, before progressively integrating farmers‟ constraints. The method was run with two groups of six and...

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.

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...

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...

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...

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.

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....

Combined use of herbivore-induced plant volatiles and sex  pheromones for mate location in braconid parasitoids
Provedor de dados: 21
Autores: Xu, Hao; Desurmont, Gaylord; Degen, Thomas; Zhou, Guoxin; Laplanche, Diane; Luka, Henryk; Turlings, Ted C.J.
Herbivore-induced plant volatiles (HIPVs) are important cues for female parasitic wasps to find hosts. Here, we investigated the possibility that HIPVs may also serve parasitoids as cues to locate mates. To test this, the odour preferences of four braconid wasps – the gregarious parasitoid Cotesia glomerata (L.) and the solitary parasitoids Cotesia marginiventris (Cresson), Microplitis rufiventris Kokujev and Microplitis mediator (Haliday) - were studied in olfactometers. Each species showed attraction to pheromones but in somewhat different ways. Males of the two Cotesia species were attracted to virgin females, whereas females of M. rufiventriswere attracted to virginmales.  Male and female M.mediator exhibited attraction to both sexes.

Combining 1,4-dimethoxybenzene, the major flower volatile of wild strawberry Fragaria vesca, with the aggregation pheromone of the strawberry blossom weevil Anthonomus rubi improves attraction
Provedor de dados: 21
Autores: Wibe, Atle; Borg-Karlson, Anna-Karin; Cross, Jerry; Bichao, Helena; Fountain, Michelle; Liblikas, Ilme; Sigsgaard, Lene.
The aggregation pheromone of strawberry blossom weevil [Anthonomus rubi Herbst (Col.: Curculionidae)], a 1:4:1 blend of Grandlure I, II and racemic lavadulol, has been available for pest monitoring for several years but shows low attractancy. Attempts to control A. rubi using the pheromone alone were also unsuccessful. This paper reports the finding that addition of the major flower volatile from wild strawberry flowers [Fragaria vesca L. (Rosaceae)], 1,4-dimethoxybenzene (comprising 98% of the volatiles emitted from wild strawberry flowers), to the aggregation pheromone increased trap catches by over two fold compared to the pheromone alone. There was no significant difference between the response of overwintered or summer emerged adults. Field trials in...

Combining agro-ecological functions in grass-clover mixtures

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...

Combining Luhmann and Actor-Network Theory to see Farm Enterprises as Self-organizing Systems
Provedor de dados: 21
Autores: Noe, Egon; Alrøe, Hugo Fjelsted.
From a rural, sociological point of view no social theories have so far been able to grasp the ontological complexity and special character of a farm enterprise as an entity in a really satisfying way. The contention of this paper is that a combination of Luhmann’s theory of social systems and the actor-network theory (ANT) of Latour, Callon, and Law offers a new and radical framework for understanding a farm as a self-organizing, heterogeneous system.     Luhmann’s theory offers an approach to understand a farm as a self-organizing system (operating in meaning) that must produce and reproduce itself through demarcation from the surrounding world by selection of meaning. The meaning of the system is expressed through the goals, values, and logic of the...

Combining mechanical rhizome removal and cover crops for Elytrigia repens control in organic barley systems
Provedor de dados: 21
Autores: Melander, Bo; Nørremark, Michael; Kristensen, E.F.
Mechanical weed control of perennial weeds in organic crop production over long post-harvest periods is incompatible with the establishment of cover crops for improving soil quality and preventing nutrient leaching. We suggest a new concept that comprises uprooting and immediate removal of vegetative propagules located within the plough layer to allow for quick re-establishment of a plant cover. A field experiment comparing the effects of conventional practices (stubble cultivation) with different combinations of rotary cultivation (1, 2 or 4 passes) and cover crops (none vs rye-vetch-mustard mixture) on Elytrigia repens rhizome removal, shoot growth and suppression of a subsequent barley crop were examined in two growing seasons. Four passes with a...

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...

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. In this study we aimed to (1) improve the effectiveness of existing traps for insect pests in...

Commencement of luteal activity in three different selection lines for milk yield and fertility in Norwegian Red cows
Provedor de dados: 21
Autores: Garmo, Randi T.; Ropstad, E.; Havrevoll, Ø.; Thuen, E.; Steinshamn, H.; Waldmann, W.; Reksen, O.
Relationships among commencement of luteal activity (C-LA), milk yield, and energy balance (EB) were investigated in 3 selection lines of Norwegian Red cows at the Norwegian University of Life Sciences from 1994 through 2001. The cows were selected for low genetic merit for milk yield (LMP), high genetic merit for milk yield (HMP), and a combination of high indices for milk yield and fertility (HI). Breeding values for fertility were based on 56-d nonreturn rate. The material included 268 lactations from 147 cows. Milk samples for progesterone analysis were drawn 3 times weekly from 1994 through 1998, and 2 times weekly from 1999 to 2001. Commencement of luteal activity was defined as the first 2 consecutive measurements of progesterone concentration &gt;3...

L’anthonome des framboises (Anthonomus rubi) et le ver des framboises (Byturus tomentosus) causent de grosses pertes dans les cultures biologiques de framboises. Dans le cadre du projet européen Core Organic 2, le projet «Softpest Multitrap» a testé une nouvelle approche pour controller simultanément ces deux ravageurs avec un piège commun, afin de proposer une alternative aux insecticides. Le but a été de définir la hauteur du piège, son design et lacombinaison de leurres optimale. Nos essais ont montré que le piège doit être posé au sol en combinant une aggregation de phéromones et des composés volatils de fleurs de framboisier pour capturer ces deux insectes. Les pièges doivent être mis en place dès le départ de la végétation (stade BBCH 45–47). Le...

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.

Communities of arbuscular mycorrhizal fungi in arable soils are not necessarily low in diversity
Provedor de dados: 21
Autores: Hijri, Isabelle; Sýkorová, Zuzana; Oehl, Fritz; Ineichen, Kurt; Mäder, Paul; Wiemken, Andres; Redecker, Dirk.
Communities of arbuscular mycorrhizal fungi (AMF) in five agricultural field sites of different management intensities were studied. Variable regions of the ribosomal RNA genes were used to detect and identify AMF directly within colonized roots. Roots from a continuous maize monoculture showed low AMF diversity, in agreement with previous reports on molecular diversity of AMF in agricultural soils. In contrast, a substantially higher diversity of AMF was found throughout the long term `DOK' field experiment, where organic and conventional agricultural practices have been compared side by side since 1978. In this experiment, a 7-year crop rotation is performed under lower levels of inorganic fertilizer input and chemical pest control. These results are in...

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...

Comparing attitudes and characteristics of  organic, former organic and conventional  farmers: Evidence from Ireland
Provedor de dados: 21
Autores: Läpple, D.
Despite an overall growth rate of the organic farming sector in the European Union, a considerable number of farmers  cease organic production each year. Given the commitment of many European governments to increase the size of their  organic farming sectors, reducing the rate of withdrawals from organic production may be an easier option than  attracting new farmers into organic farming. In order to reduce the rate of withdrawals, knowledge about those farmers is  required. However, to date, little is known about farmers who adopt and subsequently abandon organic farming. This  study attempts to fill this gap in the literature by comparing and contrasting the farm and personal characteristics of  organic, former organic and conventional farmers. To this...

Comparing Hemp Seed Yields (Cannabis sativa L.) of an On-Farm Scientific Field Experiment to an On-Farm Agronomic Evaluation Under Organic Growing Conditions in Lower Austria
Provedor de dados: 21
Autores: Vogl, C. R.; Lissek-Wolf, G.; Surböck, A.
Hemp seed yields of the variety Fedora-19 in an on-farm scientific field experiment on small plots and in an on-farm evaluation in 11 hemp fields under practical organic growing conditions in Lower Austria were compared to give a realistic view of the variability of yields. Dry matter seed yields from the on-farm field experiment ranged from 127 to 143 g/m2. Under practical growing conditions, yields ranged from 34 to 151 g/m2 in the sample plots. The reported hemp seed yield after combine harvesting, drying, and cleaning was between 324 kg/ha and 717 kg/ha. The results of the experiment show that harvesting by hand considerably influences yields. Yields of the manual harvest in sample plots indicate a high correlation with yields harvested by the combine...

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...

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’...

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.

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...

The paper describes the results of a comparison between two accreditation criteria: the IFOAM Accreditation Criteria and ISO 65 (EN 45011.   The comparison does not provide an assessment of each norm, and the format of the comparison makes it difficult to make a quick overview on the major differences. In addition, a summary and an assessment of the variations of both norms are missing.     On the other hand, the comparison enables the reader to make their own assessment and as such will be a valuable tool in the discussion and negotiations about recognition of IFOAM Accreditation.

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...

Comparison of energy and greenhouse gas balances of biogas with other transport biofuel options based on domestic agricultural biomass in Finland
Provedor de dados: 21
Autores: Tuomisto, Ms Hanna L.; Helenius, Prof. Juha.
Biofuels have been promoted as a way to reduce greenhouse gas (GHG) emissions, but it is questionable whether they indeed do so. The study compared energy and GHG balances of transport biofuels produced in Finnish conditions. Energy and GHG balances were calculated from a life cycle perspective for biogas when timothy-clover and reed canary grass silages and green manure of an organic farm were used as a raw material. The results were compared with published data on barley-based ethanol, rape methyl ester (biodiesel) and biowaste-based biogas. The energy input for biogas was 22–37% of the output depending on the raw material. The GHG emissions from field-based biogas were 21–36% of emissions from fossil-based fuels. The largest energy input was used in the...

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...

Autores: Nachimuthu, G.; King, K.; Kristiansen, P.; Lockwood, P.; Guppy, C.
In order to develop a method of measuring the level of microbial activity in soil that is suitable for use by farmers, land managers, and other non-scientists, a simple method for determining soil microbial activity was evaluated and compared with two standard techniques. Soils sampled from vegetable farms in south east Queensland were incubated in the laboratory under controlled moisture and temperature conditions. Three methods were used to measure soil microbial activity, a respirometry method and two methods using the cotton strip assay (CSA) technique (image analysis and tensometer). The standard CSA method measured loss of tensile strength over a 35 day incubation period of buried cotton strips using a tensometer. The new CSA technique measured the...

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...

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...

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...

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.

Comparison of Seafood and Agricultural Ecological Premiums1
Provedor de dados: 21
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...

Comparison of Steinernema feltiae, Bacillus thuringiensis israelensis and Azadirachtin to control Sciarids in Organic potted herbs
Provedor de dados: 21
Autores: Koller, Martin.
Sciarids (or ‘Fungus gnat’, Bradysia sp. Diptera: Sciaridae) are one of the most important pests in the organic production of potted herbs. Therefore, a method to easily monitor sciarids in pots was developed and different pest control agents were compared at FiBL CH in 2008. Our experiments showed that control with the nematode Steinernema feltiae was most successful, with an efficacy of 69–90% at 24°C air temperature. Azadirachtin (Neem-seed oil) could be an alternative under hot conditions (&gt;28°C). Bacillus thuringiensis israelensis, however, showed only a minor effect (1-51% efficacy).  Status:

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...

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;...

40 L. dorsi muscles from the left half carcass of suckling lambs raised under both organic and conventional systems were evaluated by a sixteen-member trained panel, following QDA methodology. After developing a common vocabulary for the evaluation of characteristics, 30 meat descriptors in raw and grilled meat were selected. Additionally,overall appreciation was evaluated by 140 consumers in a home-use test. The results obtained show that the appearance of the organic meat was more fibrous, darker, and with a lower aroma intensity than the conventional counterpart, but with no differences in homogeneity or juiciness. In grilled meat, the organic samples had less subcutaneous fat,less fatness, a less fibrous texture and less aroma intensity, but also less...

Organic fanning is increasingly being seen as one sustainable option to farmers, among the alternatives to conventional input intensive farming systems. Uttarakhand in India is promoting organic agriculture state state through registering the farmers and providing them necessary support including marketing in crop sector. However, these registered organic farmers, who maintain two or more than two livestock species under crop-livestock mixed farming systems, not yet geared to organic livestock production per se. As 'organic' is a process claim rather than a product claim, the study on the compatibility of animal husbandry practices of registered organic farmers  with the recommended organic livestock production standards, may provide an idea of the...

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...

The changes in weed:crop competition as affected by the interaction of slurry distribution pattern with crop sowing pattern was examined, using the parameters  dry matter (DM) production, nitrogen (N) uptake and recovery of applied N in spring wheat and weeds. Pig slurry enriched with isotopic nitrogen (15N) was applied either fully incorporated or in concentrated bands. The two slurry distribution patterns were combined with either crop density or distance between the slurry band and seed row. Spring wheat and weeds were sampled separately seven times during the season. A high and fast crop recovery of applied N coincident with a low recovery in weeds may be obtained by at least three management elements: sowing the crop with a high seed density, sowing...

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...

Complex interplay of future climate levels of CO2, ozone and temperature on susceptibility to fungal diseases in barley
Provedor de dados: 21

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.

O presente trabalho teve objetivo de observar o comportamento de variedades de mandioca submetidas a fertilização, nas comunidades dependentes de chuva Pereiros, Mudubim e Caiçara no semiárido brasileiro. Apesar do conhecimento sobre a tolerância da mandioca ao déficit hídrico e solos marginais, pouco se sabe sobre o potencial produtivo de diferentes variedades sob uso de adubação em áreas dependentes de chuva no semiárido. Foram conduzidos experimentos participativos com adubação e variedades de mandioca em três comunidades de áreas dependentes de chuva de Petrolina-PE. Os resultados mostram que apesar do baixo índice pluviométrico no período (entre 209 e 747mm), a calagem e fertilização com fósforo proporcionou melhoria da fertilidade do solo e maiores...

Demand for organic meat is partially driven by consumer perceptions that organic foods are more nutritious than non-organic foods. However, there have been no systematic reviews comparing specifically the nutrient content of organic and conventionally produced meat. In this study, we report results of a meta-analysis based on sixty-seven published studies comparing the composition of organic and non-organic meat products. For many nutritionally relevant compounds (e.g. minerals, antioxidants and most individual fatty acids (FA)), the evidence base was too weak for meaningful meta-analyses. However, significant differences in FA profiles were detected when data from all livestock species were pooled. Concentrations of SFA and MUFA were similar or slightly...

Provedor de dados: 21
Autores: Konvalina, Petr; Capouchova, Ivana; Stehno, Zdenek; Moudry, Jan (Jr.); Moudry, Jan (Jr.).
Tetraploid emmer wheat [(Triticum dicoccum (Schrank) Schuebl] has become a more attractive crop for growing in marginal areas and for the organic farming system. As it provides a lower yield rate and has a specific quality, it is an exclusive food crop. Therefore, the proportion and nutritive quality of particular essential amino acids (threonine, valine, isoleucine, leucine, tyrosine, phenylalanine, lysine, methionine) and the total protein content were studied and evaluated in three-year trials carried out in two different localities. Furthermore, old and modern bread wheat varieties were compared. Results of our research confirmed a high crude protein content in grains of all the landraces of the emmer wheat. The emmer wheat variety contained 5% more...

Volatile compounds in skim milk and nonstandardised milk  subjected to instant infusion pasteurisation at 80°C, 100°C and 120°C were compared with raw milk, high temperature short time pasteurised milk and milk pasteurised at 85°C/30 s. The composition of volatile compounds differed between infusion pasteurisation treated samples and the reference pasteurisations. The sensory properties of skim milk subjected to instant infusion pasteurisation were described by negative attributes, such as cardboard sour and plastic flavours, which are not associated normally with fresh milk. Partial least squares modelling showed good correlation between the volatile compounds and the sensory properties, indicating the predictive and possible causal importance of the...

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...

Composting rapidly degrades DNA from genetically modified plants
Provedor de dados: 21
Autores: Rasmussen, L.D.; Møller, J.; Magid, J.
Organic farmers are concerned about the use of genetically modified plants (GM plants) in conventional agriculture. The concern is mainly focused on the risk of spreading of pollen or seeds from GM plans to adjacent fields.    There has been less focus on the environmental impact of exposing the soil to genetically modified DNA (i.e. transgenic DNA) from GM plants residues left in the field. Yet, the new EU directive on the deliberate release into the environment of genetically modified organisms (EU, 2001) requires a "description of post-release treatment methods for the genetically modified plant material including wastes".

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...

Compressive behaviour of the soil in buffer zones under different management practices in Finland
Provedor de dados: 21
Autores: Räty, Mari; Horn, Rainer; Rasa, Kimmo; Yli-Halla, Markku; Pietola, Liisa.
Soil structure that favours infiltration is essential for successful functioning of vegetated buffer zones. We measured bulk density, air permeability and precompression stress in a clay soil (Vertic Cambisol) and a sandy loam (Haplic Regosol) in Finland, to identify management-related changes in the physical and mechanical properties in the surface soil of buffer zones. In addition, the impact of texture on these properties was studied at depths down to 180?200 cm. Soil cores (240 cm3) were sampled from a cultivated field, from buffer zones harvested by grazing (only in a clay soil) or by cutting and removing the vegetation, and from buffer zones covered with natural grass vegetation. The samples were equilibrated at a matric potential of -6 kPa and...

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...

Provedor de dados: 21
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: 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...

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...

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...

Concepts of Animal Health and Welfare in Organic Livestock Systems
Provedor de dados: 21
Autores: Vaarst, Mette; Alrøe, Hugo Fjelsted.
In 2005, The International Federation of Organic Agricultural Movements (IFOAM) developed four new ethical principles of organic agriculture to guide its future development: the principles of health, ecology, care, and fairness. The key distinctive concept of animal welfare in organic agriculture combines naturalness and human care, and can be linked meaningfully with these principles. In practice, a number of challenges are connected with making organic livestock systems work. These challenges are particularly dominant in immature agro-ecological systems, for example those that are characterized by industrialization and monoculture. Some of the current challenges are partly created by shortages of land and manure, which encourage zero-grazing and other...

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...

Conceptual and user-centric design guidelines for a plant nursing robot
Provedor de dados: 21
Autores: Sørensen, C.G.; Jørgensen, R.N.; Maagaard, J.; Bertelsen, K.K.; Dalgaard, L.; Nørremark, M.
Current service robots have relatively primitive behaviours and limited interaction with the environment. Technological foresights have indicated that the next generation of service robots will demonstrate a high degree of autonomy and reliability, have minimal impact on the environment, and will interact in a flexible way with the user. 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...

Autores: Castel, Laurie; Plessix, Segolene; Gaspari, Chloe; WARLOP, FRANCOIS.
The VERtiCAL research project focused from 2013 to 2018 on the spatial and temporal diversification of fruit tree systems as a relevant mean for reducing pesticide use. The project resulted in the design and assessment of two fruit agroforestry systems (AFS), called "TAB" and "Durette", managed in organic farming and with specific technical and economic characteristics. The project allowed co-design experiences and led to the development of a new tool for ex ante assessment of AFS. First results show a 52% reduction of pesticides on the TAB system compared to a conventional reference system while reaching yield objectives, and a very low reliance to pesticides on the Durette system. As for biodiversity, specific richness of birds increased from 12 to 24...

Confirmation that pulse and continuous peracetic acid administration does not disrupt the acute stress response in rainbow trout
Provedor de dados: 21
Autores: Gesto, Manuel; Liu, Dibo; Pedersen, Lars-Flemming; Meinelt, Thomas; Strauss, David L.; Jokumsen, Alfred.
Peracetic acid (PAA) is considered an eco-friendly alternative to other antimicrobial agents of common use in aquaculture. The literature suggests that fish can habituate to PAA exposure based on a reduction of the fish corticosteroid response to PAA administration after repeated exposures. If that is true, PAA would also be a good option from the point of view of fish physiology. However, stronger evidence is needed to confirm that the use of PAA is welfare-friendly to fish. Besides habituation, other hypothetical factors such as desensitization, physiological exhaustion or PAA-mediated endocrine disruption could potentially explain the reduction in the corticosteroid response after repeated/prolonged PAA exposure. In this study, rainbow trout that had...

Autores: Butler, Gillian; Collomb, Marius; Rehberger, Brita; Sanderson, Roy; Eyre, Mick D.; Leifert, Carlo.
BACKGROUND: Different conjugated linoleic acid (CLA) isomers are known to have contrasting physiology or health effects and there is growing evidence that the profile of natural isomers in milk is influenced by the production system. This survey is the first to compare feeding regimes and concentrations of 14 CLA isomers inmilk from three production systems in the UK.  RESULTS: Total CLA and seven isomers (including C18 : 2 c9t11 which comprised &gt;80% of total) were significantly higher in milk from both organically certified and non certified low input (LI) systems compared with milk from conventional high input farms. Sampling date also affected concentrations of total CLA and nine isomers; being lowest in March and highest in August.  Seasonal...

Consequences of field N2O emissions for the environmental  sustainability of plant-based biofuels produced within an organic farming system
Provedor de dados: 21
Autores: Carter, Mette S.; Hauggaard-Nielsen, Henrik; Heiske, Stefan; Jensen, Morten; Thomsen, Sune T.; Schmidt, Jens Ejbye; Johansen, Anders; Ambus, Per.
One way of reducing the emissions of fossil fuel-derived carbon dioxide (CO2) is to replace fossil fuels with biofuels produced from agricultural biomasses or residuals. However, cultivation of soils results in emission of other greenhouse gasses (GHGs), especially nitrous oxide (N2O). Previous studies showed that field emissions of N2O may contribute significantly to total GHG emissions during biofuel production. Furthermore, N2O may counterbalance a considerable part of the global warming reduction, which is achieved by fossil fuel displacement. In the present study, we related measured field emissions of N2O to the reduction in fossil fuel-derived CO2, which was obtained when agricultural biomasses were used for biofuel production. The analysis included...

Consequences of including adapted white clover in northern European grassland: transfer and deposition of nitrogen
Provedor de dados: 21
Autores: Gylfadóttir, Thórey; Helgadóttir, Áslaug; Høgh-Jensen, Henning.
The interspecific transfer of nitrogen (N) between white clover (Trifolium repens) and smooth meadow grass (Poa pratensis) in legume-based grasslands was assessed under North European field conditions using 15N individual plant leaf labelling. On average 50% of N in the grass was transferred from the white clover and about 6% of N in white clover was transferred from the grass. This corresponds to 2.5 and 0.3 g N m-2 being transferred over the growing season between the two species respectively and demonstrates that a significant part of the total N of the grass is coming through interspecific transfer. The majority of the 15N transferred was within a period of 20 days at relatively low soil temperatures. This implies that there is a need for a new focus...

Consequences of the introduction of cereal - grain legume intercrops in the supply chain. Analysis from the perspective of farmers and cooperatives
Provedor de dados: 21
Autores: Bedoussac, Laurent; Triboulet, P.; Magrini, M.-B.; Rambault, G.; Foissy, Damien; Corre-Hellou, Guénaëlle.
Intercropping (the simultaneous growth of 2 or more species in the same field) is one way to solve some difficulties that organic supply chain has to face. The aim of this article is to assess the consequences and the compatibility with intercrops at 2 levels: i) cropping systems of 18 farmers from north of France and ii) the logistics ofagricultural cooperatives which collect durum wheat in Midi-Pyrenees altogether with two cooperatives that already had experimented intercrops (Terrena and AgriBioUnion).The conclusions of our work is that intercrops seem a priori compatible with farmers’ cropping systems and with the presentlogistic organization of cooperatives but the main difficulty remains the feasibility and the cost in sorting out grains.

Conservation science relevant to action: A research agenda identified and prioritized by practitioners
Provedor de dados: 21
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...

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...

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...

Um dos principais problemas ambientais causados pela agricultura é a degradação dos solos. Dentre as formas de erosão, as voçorocas são as que causam conseqüências mais graves à população rural em termos de perda de área utilizável, assoreamento de rios entre outros. No assentamento Olga Benário este problema é constatado e percebido em algumas áreas pelas famílias assentadas, sendo um fator que traz prejuízos à comunidade, sob o ponto de vista econômico e ambiental. A partir da visualização deste problema, desenvolveu-se um projeto pedagógico no sentido de construir conhecimentos para o entendimento dos processos relacionados com erosão e formação das voçorocas.

Consumer attitudes towards organic fish
Provedor de dados: 21
Autores: Nielsen, Thorkild.
This paper is dealing with consumer’s attitudes to organic fish. It is part of the research project RobustFish. The overall aim of RobustFish was to strengthen the development of Danish organic aqua culture. Surveys performed among consumers showed that the knowledge about sustainability and organic fish is relatively fragmentary; e.g. stories from the media detached from the context “overfishing”, not healthy fish farmed in Asia etc. Very few consumers were able to identify specific rules for organic fish, and often they were mixed up with the MSC certification.

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...

Consumer motivations in the purchase of organic food. A means-end approach
Provedor de dados: 21
Autores: Zanoli, Prof Raffaele; Naspetti, Dr. Simona.
The paper presents partial results from an Italian study on consumer perception and knowledge of organic food and related behaviour. The means-end chain model was used to link attributes of products to the  needs of consumers.  In order to provide insights into consumer motivation in purchasing organic products, 60 respondents were interviewed using “hard” laddering approach to the measurement of means-end chains.  The results (ladders) of these semi-qualitative interviews are coded, aggregated and presented in a set of hierarchical structured value maps. Consumer cognitive structures at different level of experience are reported and discussed.  Even if organic products are perceived as difficult to find and expensive, most of consumers judge them...

Consumer perception of different organic certification schemes in five European countries
Provedor de dados: 21
Autores: Janssen, Meike; Hamm, Ulrich.
With the introduction of the new mandatory EU logo for organic food and farming, the various existing organic certification schemes in the European market face a challenge: Producers and retailers might only continue to display the existing organic logos on product packages if the underlying certification schemes offer consumers an added value compared to the mandatory EU logo and its scheme. The present study aims to identify potential added values that organic certification schemes could incorporate to differentiate themselves from the mandatory EU logo. The study explores consumer awareness and perception of different organic certification schemes and the corresponding logos, about which little is known to date. The qualitative approach with focus group...

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...

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...

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...

Consumer preferences for ‘localness’ and organic food production
Provedor de dados: 21
Autores: Denver, Sigrid; Jensen, Jørgen Dejgård; Olsen, Søren Bøye; Christensen, Tove.
Purpose:  A number of previous studies have analyzed the interface between consumer preferences for organic and local food. While organic food is based on well-defined production criteria, local food is less well defined and is often used to describe a variety of food characteristics. This study investigates Danish consumers’ preferences and trade-offs for organic production and multiple commonly mentioned, dimensions of local food: sales channel, size of company, and geographic location of animals used in the production focusing on differences between consumer segments.     Design/methodology/approach:  The analysis is based on a quantitative survey among 505 consumers and includes a choice experiment concerning preferences for beef salami. Data from the...

Consumer preferences for organic food and for the shares  of meat and vegetables in an everyday meal
Provedor de dados: 21
Autores: Denver, Sigrid; Olsen, Søren Bøye; Christensen, Tove.
It is well established that consumers with positive preferences for organic products generally also tend to have healthy eating habits involving many fruits and vegetables but little meat. While most studies are based on single product comparisons, this study investigates consumer preferences for organic ingredients and content of meat and vegetables in the context of an everyday evening meal. Moreover, we address heterogeneity in preferences. The study is based on an online survey including a choice experiment with 506 consumers. Using principal component and latent class analyses we identify three segments of consumers that differ with respect to preferences for organic production and content of meat and vegetables in their meals. Our findings may be...

Using data from focus group discussions with consumers and a choice experimentconducted in some of Turkey’s major cities, this study investigates whetherTurkish consumers prefer certain organic labelling schemes over others attemptsand to elicit their willingness to pay (WTP) for different organic certificationlogos. Although the level of awareness regarding organic certification logos waslow, consumers’ perceptions of the logos were generally positive. The results ofthe random parameter logit models indicated a positive WTP for the presence ofone of the three tested certification body logos in addition to the mandatorygovernmental logo. Given the low level of certification logo awareness, theconclusion is that both purchasing decisions and perceptions...

Consumer-driven climate change mitigation – will organic food consumption make a positive difference?
Provedor de dados: 21
Autores: Heerwagen, Lennart Ravn; Andersen, Laura Mørch; Sandøe , Peter; Christensen, Tove.
Almost two out of three organic consumers state that mitigating climate change is an important reason for buying organic products. This finding may constitute a challenge for the organic market, considering the conflicting scientific evidence that underlies the belief that organic production is better for the climate than conventional production. However, several studies indicate that consumers of organic food in Denmark and other northern European countries purchase less meat than other consumers, and meat production has been identified as a major contributor to greenhouse gas emissions. Inspired by these findings, we ask whether anthropogenic climate change could be mitigated by patterns of organic food consumption. Using unique Danish data on stated...

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...

Autores: Kesse-Guyot, E.; Péneau, S.; Méjean, C.; Szabo de Edelenyi, F.; Galan, P.; Hercberg, S.; Lairon, D.
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...

Autores: Feldmann, Corinna; Hamm, Ulrich.
This article reviews the scientific literature on local food from the consumer’s perspective and analyses findings through the application of the Alphabet Theory – a newly developed theoretical framework for consumer behavior towards alternative food choices. As consumers’ interest in local food has steadily increased in the past fifteen years, so has the number of research studies on consumers’ attitudes and purchase behavior with regard to local food.  A literature search was carried out on three online catalogues using the search terms ‘local’, ‘regional’, ‘food’, and ‘consumer’. Only articles published in English and from January 2000 until January 2014 were taken into account. In all, the literature search returned 550 scientific articles. This paper...

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...

Berry-based products that have beneficial effects on consumer health are competitive on the market only if consumers understand the benefits of such products. The purpose of this research was to gain in-depth analysis of the factors that influence the consumer choices and behavior towards berry based food products in three different countries, from eastern and western Europe: Romania, France and Turkey. These three countries as a three distinctive markets for organic products were chosen to find out similar and different attitudes and behavior towards organic food consumption. This cross-cultural consumer study aims to contribute to socioeconomic research market actors and policy makers. French consumers appear to be the most loyal consumers of...

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...

Contamination of oilseed rape varieties by pollen and seeds
Provedor de dados: 21
Autores: Simonsen, Vibeke; Damgaard, Christian; Kjellsson, Gösta.
Oilseed rape (Brassica napus) is a common crop in Denmark and mainly cultivated for its content of oil used for food and feed. The species is often genetically modified (GM), e.g. to herbicide tolerance or insect resistance. Spread of the inserted genes is likely to occur not only to the species itself, but also to its close relatives. The study showed a significant difference between phenotypes in the certified seeds and phenotypes in plants and in seeds in the field. The reason for this might be the presence of OSR volunteers from a previous crop surviving in the soil seed bank. This type of contamination is affected by e.g., harvest and post-harvest handling procedures (Fargue et al., 2003) and can consequently be reduced.     More studies on...

Autores: Steenfeldt, S.; Horsted, K.; Sørensen, P.
A study with organic broilers with access to a large range area with herbs was performed and the effect of three broiler genotype (JA757, T851, SU51) with different growth rates and different feeding strategies (HP vs LP) on the animals' feed intake, growth and welfare was investigated. The results so far indicate that feed intake from range and animal welfare is dependent on type of allocated feed and growth rate of the broiler genotype. Thus, gait scores and foot and plumage condition showed that the fastest growing broiler genotype had some problems when fed normal broiler feed, whereas this was not the case for the other genotypes. The fastest growing broilers also ate more pelleted broiler feed compared to the slower growing breeds, which in contrast...

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...

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...

Autores: Jespersen, Lizzie Melby; Baggesen, Dorte Lau; Fog, Erik; Halsnæs, Kirsten; Hermansen, J.E.; Andreasen, Lise; Strandberg, Beate; Halberg, Niels.
The potential contribution of organic farming to the public goods, ‘Nature and Biodiversity’, ‘Environment’, ‘Energy and Climate’, ‘Human Health and Welfare’ and ‘Animal Health and Welfare’ in Denmark is guided and partly secured by the principles and specific requirements of the EU Organic Regulation. However, other factors, such as the production type, farm size, geographical location and—not the least—the management of the farm, also influence the contribution. Using the ban on synthetic pesticides and restricted use of antibiotics, including the requirements to compensate for and prevent such uses in organic farming, as examples, the positive and negative contributions of organic farming in relation to selected public goods were analysed. The...

Contributions to variability of Clinical Measures for use as Indicators of Udder Health Status in a Clinical Protocol
Provedor de dados: 21
Autores: Fossing, C.; Vaarst, M.; Houe, H.; Enevoldsen, C.
A cross-sectional observational study with repeated observations was conducted on 16 Danish dairy farms to quantify the influence of observer, parity, time (stage in lactation) and farm on variables routinely selected for inclusion in clinical protocols, thereby to enable a more valid comparison of udder health between different herds. During 12 months, participating herds were visited 5 times by project technicians, who examined 20 cows and scored the selected clinical variables. The estimates of effect on variables were derived from a random regression model procedure. Statistical analyses revealed that, although estimates for occurrence of several the variables, e.g. degree of oedema, varied significantly between observers, the effects on many of these...

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...

Autores: Caleca, Virgilio; Lo Verde, Gabriella; Lo Verde, Valentina; Palumbo Piccionello, Manuela; Rizzo, Roberto.
Tests on the effect of clays (kaolin and bentonite) and copper products  (hydroxide and oxychloride) in the control of olive fruit fly, Bactrocera oleae (Rossi), and Mediterranean fruit fly, Ceratitis capitata (Wiedemann), were carried out from 2003 to 2006 in olive groves and in organic citrus orchards (satsuma, clementine, ‘Navelina’ orange). Results demonstrate an efficacy of kaolin products in reducing attacks of B. oleae on olives and those of C. capitata on citrus fruits; in olive groves the clays gave similar or better results than copper hydroxide. Bentonite AG/8W showed a significant reduction in punctures by C. capitata. Bentonite products and BPLK kaolin are washed off by rainfall more easily than Surround WP kaolin.

Control of enteric pathogens in ready-to-eat vegetable crops in organic and ‘low input’ production systems: a HACCP-based approach
Provedor de dados: 21
Autores: Leifert, C.; Ball, K.; Volakakis, N.; Cooper, J.M.
Risks from pathogens such as Salmonella, Yersinia, Campylobacter and Escherichia coli O157 have been identified as a particular concern for organic and ‘low input’ food production systems that rely on livestock manure as a nutrient source. Current data do not allow any solid conclusions to be drawn about the level of this risk, relative to conventional production systems. This review describes six Risk Reduction Points (RRPs) where risks from enteric pathogens can be reduced in ready-to-eat vegetables. Changes can be made to animal husbandry practices (RRP1) to reduce inoculum levels in manure. Outdoor livestock management (RRP2) can be optimized to eliminate the risk of faecal material entering irrigation water. Manure storage and processing (RRP3), soil...

Control of the risk of human toxoplasmosis transmitted by meat
Provedor de dados: 21
Autores: Kijlstra, Prof.Dr. Aize; Jongert, Dr. Erik.
One-third of the human world population is infected with the protozoan parasite Toxoplasma gondii. Recent calculations of the disease burden of toxoplasmosis rank this foodborne disease at the same level as salmonellosis or campylobacteriosis. The high disease burden in combination with disappointing results of the currently available treatment options have led to a plea for more effective prevention. In this review we describe Toxoplasma as a hazard associated with the consumption of undercooked meat or meat products and provide an analysis of the various options to control the risk of human toxoplasmosis via this source. Monitoring and surveillance programs may be implemented for pre-harvest control of Toxoplasma infection of farm animals, with the...

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...

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,...

Controlling risks of pathogen transmission by flies on organic pig farms - A review
Provedor de dados: 21
Autores: Meerburg, Dr. BG; Vermeer, MSc., HM; Kijlstra, Prof dr A.
Fly prevention and control on animal production units is necessary to prevent the transmission of pathogens that could affect animal and human health and the maintenance of good hygiene. Organic farmers are often hesitant to apply insecticides for this purpose because of their farming philosophy. Organic production systems are relatively open as pigs generally have access to the outdoors. Here, we investigate the need for fly control and analyse various possibilities that organic farmers have to reduce the number of flies on their farms. We conclude that although biological control looks promising, more research should be done concerning its side effects. Currently, optimal monitoring and prevention seem to offer the best solution.

Provedor de dados: 21
Autores: Ranca, Aurora-Maria; Petrescu, Anamaria; Artem, Victoria; Boloș, P.; Cîlț, Mihaela; Ene, A.S.
The capability of plants of increasing the ecosystem resistance to pests and invasive species is a well-known ecosystem service. However, monocultures (including vineyards) do not exploit the potential of plant diversity. The aims of this research are to develop new viticultural systems based on increased plant diversity within (e.g., cover crops) and/or around (e.g., hedges, vegetation spots, edgings) vineyards by planting selected plant species for the control of arthropods, soil-borne pests (oomycetes, fungi, nematodes), and foliar pathogens. In order to control pests, plants species can either i) repel arthropod pests, ii) attract arthropod pests to a trap crop or iii) attract and/or conserve beneficials. An extensive systematic literature was...

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...

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....

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...

To evaluate the animal nutritional status of copper, molybdenum and cobalt on Norwegian organic farms, soil, herbage and animal blood samples were collected from 27 dairy and sheep farms and analysed for Cu, Mo and Co. The herbage median (10th-90th percentile) Cu, Mo, and Co concentrations (mg/kg DM) and the Cu:Mo ratio in the first cut were 5.3 (3.9-6.8), 1.5 (0.6-4.8), &lt;0.05 (&lt;0.05-0.08) and 3.8 (1.1-8.3) and in the second cut 7.0 (5.7-9.3), 3.3 (1.6-10.1), 0.06 (&lt;0.05-0.15) and 2.0 (0.8-5.2), respectively. The results of mixed model analyses of herbage Cu and Mo indicated that soil pH, soil organic matter content, herbage botanical composition, yield and phenological stage of timothy at harvest mostly influenced the herbage micronutrient...

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...

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...

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...

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...

Provedor de dados: 21
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.

Cover crops and compost influence soil enzymes during 6 years of tillage-intensive, organic vegetable production
Provedor de dados: 21
Autores: Brennan, Eric B.; Acosta-Martinez, Veronica.
Soil enzymes are considered sensitive indicators of soil health but are not well understood in tillage-intensive vegetable systems. The activities of soil enzymes involved in nutrient cycling (β-glucosidase, β-glucosaminidase, alkaline phosphatase, dehydrogenase, aspartase, and L-asparaginase) were evaluated during 6 yr of commercial-scale production in five organic vegetable systems in Salinas, CA. The systems differed in yard-waste compost inputs (none or 15.2 Mg ha–1 yr–1), winter cover crop frequency (annually or every fourth year), and cover crop type (legume-rye, mustard, or rye). Large differences in cumulative organic matter input (7.4 to 136.8 Mg ha–1) from compost and cover crop shoots affected soil enzyme activities. With exception of aspartase,...

Autores: Pedersen, Hanne Lindhard.
With the objective to identify the effect of soil cultivation and nitrogen supply in organic production of blackcurrant a field trial was planted autumn 1996 under unsprayed conditions. The bush rows were cleaned mechanically for weed, and cover crops were established in the alleyways.   During establishment all four cover crops gave a sufficient nitrogen supply. The level of nitrogen in soil and the growth were smallest in the annual sown cover crop. Miniritzotrons were used to follow blackcurrant root growth in total mechanical cleaned plots and plots with sown alleyways. The maximum root dept of blackcurrants of 125 cm were obtained direct under the bush in autumn 1998, whereas the roots only were present down to 40 cm 1.5 meters from the centre of the...

Cowpea (Vigna unguiculata L. Walp.) is an important African food legume suitable for dry regions. It is the main legume in two contrasting agro-ecological regions of Kenya as an important component of crop rotations because of its relative tolerance to unpredictable drought events. This study was carried out in an effort to establish a collection of bacterial root nodule symbionts and determine their relationship to physicochemical soil parameters as well as any geographical distributional patterns. Bradyrhizobium spp. were found to be widespread in this study and several different types could be identified at each site. Unique but rare symbionts were recovered from the nodules of plants sampled in a drier in-land region, where there were also overall more...

Creation of innovative tools for the development of organic dairy production in mountain areas
Provedor de dados: 21
Autores: Dockès , Anne-Charlotte; Boisdon, Isabelle; Experton , Catherine; Fourdin, S.
In the dairy mountain areas, natural constraints and the end of the quota system are sources of difficulties and challenges for the dairy production. High added value schemes, such as organic farming could help farmers and processors to face these challenges. The “Montagne Bio project”, funded by the French Ministry of Agriculture studied and defined the conditions for the success of this development. We studied dairy farmers’ views on organic production, described farm trajectories before and after conversion, and identified factors that contribute to the success or the failure of a conversion or of a collective development project. We tested and assessed a method to carry out projects for the development of organic farming in rural areas and built tools...

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...

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). The utilization...

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...

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...

Crop yield, root growth, and nutrient dynamics in a  conventional and three organic cropping systems with  different levels of external inputs and N re-cycling through fertility building crops
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....

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...

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.

Worldwide interest in soil quality evaluation has increased rapidly throughout the past decade, prompting us to evaluate the long-term impact of four cropping systems on several biological, chemical and physical determinants of soil quality. We hypothesized that after 17 years several of the determinants would show significant differences between conventional cereal and low input/organic rotations. Four crop rotations were imposed on a silt soil from 1982 through 1999. Rotation A was a conventionally managed cereal rotation that received 100% of the recommended mineral fertilizer each year. Rotation B was also managed conventionally from 1982 until 1993, although it received only 50% of the recommended mineral fertilizer. From 1994 through 1999, rotation B...

Autores: Rodionov, A.; Nii-Annang, S.; Fischer, T.; Gattinger, A.; Bens, O.; Raab, T.; Hüttl, R. F.
Application of hydrophilic polymers composed of cross-linked polyacrylate can improve soil water-holding capacity and accelerate the restoration of post-mining substrates. In this work, we studied the persistence of a polyacrylate polymer incorporated into a soil and its impact on plant nutrients at a reclamation site of former lignite mining in Lusatia (Germany). In contrast to autumn application, the incorporation of the polymer enhanced the sequestration of plant-derived carbon in the soil, which was reflected by a significant increase in the concentration of a lignin marker. Attenuated total reflexion–Fourier transform infrared spectra (ATR-FTIR) and total elemental contents in the applied polymer suggested an intensive cation exchange between the...

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...

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...

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...

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. Yield (kg ha-1) was recorded and grain/seed nitrogen content...

Cultivars and cultivation systems for organic strawberry production in Norway
Provedor de dados: 21
Autores: Nes, Arnfinn; Henriksen, Jan Karstein; Serikstad, Grete Lene; Stensvand, Arne.
Cultivars and cultivating methods for organic strawberry production were studied in experiments in open fields and high plastic tunnels during four cropping seasons in southern Norway. In open fields, flowers and fruits were attacked by grey mould when the flowering and harvest seasons were wet, and marketable yield was reduced by up to 20%. Production in high tunnels showed a potential of high yields of fruits of good quality when strawberry powdery mildew was controlled. Berry size varied significantly among the cultivars. ‘Frida’ had the largest fruits followed by ‘Sonata’ and ‘Florence’, while ‘Polka’, ‘Korona’ and ‘Iris’ had the smallest fruits. All cultivars yielded well, but due to fruit decay caused by grey mould the marketable yield was...

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...

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)...

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...

Autores: Granatstein, David; Kirby, Elisabeth; Willer, Helga.
Consumption of organic food has steadily increased in the primary markets of the European Union and North America. However, the statistical information base to describe this growth is either incomplete or inaccessible and sometimes inaccurate. In the USA, fruits and vegetables make up 40% of organic food sales, implying that the expanding overall market has also increased demand for organic temperate fruits such as apple, grape, and strawberry. Organic fruit in several European countries comprises over 5% of all fruit sales. Data on organic temperate fruit production have been compiled by FiBL and Washington State University. In 2006, there were at least 250,000 ha of organic temperate fruit (pome, stone, grapes, and berries) under production worldwide...

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...

Dalmore Farm (1933-1934) was Victoria’s first biodynamic farming venture. A letter, written in Milan, Italy, in Italian in 1934 by Rosa Genoni (1867-1954) \ enables details of this venture to be finally revealed. Rosa wrote of her youngest brother, Ernesto Genoni (1885-1975): “Now Ernesto … is at Dalmore, a farm of my brother Marino (the father of the boy [Alfredo Genoni (1913-1999)] who was sent to us years ago from Australia and we sent him to Dornach where he stayed for two years, and two more to the school at Stuttgart) and in part by my brother Angelo, who asked Ernesto to go and organise the farm biologically”. “Ernesto had a small wooden house built there for his use.

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...

Bei potenziellen Zeichennutzern stößt das Zeichen allerdings auf nur mäßige Akzeptanz, Ziel der Untersuchung war es daher, die Ursachen für die geringe Nutzung des ÖPZs in Industrie und Handel zu analysieren. Den Ergebnissen zufolge ist eine erfolgreiche Einführung des Öko-Prüfzeichens nicht zu erwarten. Gründe hierfür sind in den zu Grunde liegenden Vergabemodalitäten zu suchen, so insbesondere in der Anbindung an die AGÖL-Rahmenrichtlinien und in der Höhe der Lizenzgebühren.

Zukünftige agrarpolitische Reformvorhaben (WTO-Liberalisierung, EU-Agrarfreihandel) werden die Schweizer Landwirtschaft vor neue Herausforderungen stellen. Da sich einzelne Produktionsbereiche in ihrer internationalen Konkurrenzfähigkeit teilweise deutlich unterscheiden, ist davon auszugehen, dass die Auswirkungen einer weiteren Liberalisierung sehr unterschiedlich ausfallen können. Um die Wirkung agrarpolitischer Massnahmen möglichst differenziert analysieren zu können, wurde am Forschungsinstitut für biologischen Landbau (FiBL) das Agrarsektormodell CH-FARMIS auf der Grundlage des deutschen FARMIS Modells entwickelt. Das Modell basiert auf einer repräsentativen Stichprobe von Landwirtschaftsbetrieben. Die Betriebe werden zu Betriebsgruppen...

Decentralizing and liberalizing EU regulations on seeds and plant genetic resources. A Danish case study
Provedor de dados: 21
Autores: Turpin, Grégoire; Boelt, Birte.
In a context of severe plant genetic diversity erosion, the regulatory framework of the European Union on seeds and plant genetic resources is perceived as a limiting factor to practices aiming to conserve cultivated biodiversity. To create more supportive frameworks, some EU member states liberalized seed trade and landraces cultivation regulations at national or regional level. For this paper, a case study of the 2015 cereal and vegetable seed legislation reform in Denmark has been carried out. Interviews with stakeholders of the seed system, with farmers and project leaders impacted by this change and with key informant on the regulation, from NGOs and public authorities, have been carried out. Inductive and deductive analysis methods enabled the themes...

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...

Decomposition and nutrient release of leguminous plants in coffee agroforestry systems.
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...

Decomposition of white clover (Trifolium repens) and ryegrass (Lolium perenne) components: C and N dynamics simulated with the DAISY soil organic matter submodel
Provedor de dados: 21
Autores: de Neergaard, Andreas; Hauggaard-Nielsen, Henrik; Jensen, Lars Stoumann; Magid, Jakob.
Using data from a decomposition study, we aimed to test the parameterisation of the soil organic matter module of the DAISY model, and link measurable plant litter fractions (lignin, water-soluble) with the model defined plant litter pools. Shoot and root material from perennial ryegrass and white clover was incubated in a sandy loam soil at 9 °C for 94 days. Accumulated CO2 evolution, soil mineral nitrogen (N) and soil microbial biomass-N were measured during the incubation. Marked differences in decomposition rates between above- and below-ground material as well as between the two plant species were observed. The DAISY model was used to interpret the incubation results. Decomposition rates and utilisation efficiencies were modified, under the constraint...

Deep roots of Brassica oleracea have high uptake of 15N-nitrate to 2 meters soil depth
Provedor de dados: 21
Autores: Kristensen, H.L.; Thorup-Kristensen, K.
• Deep roots may be important for uptake of NO3- by annual crops. A field experiment with the deep rooted crop curly kale (Brassica oleracea L. convar. acephala (DC.) Alef. var. sabellica L.) was performed to investigate root distribution and N uptake in deep soil layers.  • Root distribution was investigated by use of minirhizotrons and root extractions to 2.4 m depth. The capacity for crop N uptake was studied by deep 15NO3- placement followed by analysis of plant 15N content after 3-30 days.   • The atom percent 15N excess (APE) of plant samples was of similar size after uptake of 15N placed at depths in the range of 0.4-2 m. Root colonisation and start of 15N uptake were synchronized in 2.4 m depth.  • The deep roots had higher inflow of 15N compared...

Autores: Van Zanten, Hannah H.E.; Herrero, Mario; Van Hal, Ollie; Röös, Elin; Müller, Adrian; Garnett, Tara; Gerber, Pierre J.; Schader, Christian; de Boer, Imke J.M.
The need for more sustainable production and consumption of animal source food (ASF) is central to the achievement of the sustainable development goals: within this context, wise use of land is a core challenge and concern. A key question in feeding the future world is: how much ASF should we eat? We demonstrate that livestock raised under the circular economy concept could provide a significant, nonnegligible part (9–23 g/per capita) of our daily protein needs (~50–60 g/per capita). This livestock then would not consume human‐edible biomass, such as grains, but mainly convert leftovers from arable land and grass resources into valuable food, implying that production of livestock feed is largely decoupled from arable land. The availability of these biomass...

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...

Delicious words - assessing the impact of short storytelling messages on consumer preferences for variations of a new processed meat product
Provedor de dados: 21
Autores: Fenger, Morten; Aschemann-Witzel, Jessica; Hansen, Flemming; Grunert, Klaus.
In this paper we present an experiment that tests the possible effect of adding the short type of "story" that is possible on a food label to variations of a product that is differentiated by its ingredients and way of production. We conduct an experiment where consumers have to choose from products consisting partly of this new type of product, partly of conventional products well known to consumers. We find that that while some consumers – especially those seeking stimulation and with a tendency towards variety seeking – will favor the new product, others will remain uninterested. We then test whether the introduction of an additional element of storytelling, on top of the information on ingredients and process, has an effect on choice. We find...

O código florestal brasileiro define como áreas de proteção permanente (APPs) os topos dos morros. Estes foram regulamentados pela resolução CONAMA 303/2002, que estabelece que o terço superior de morros e montanhas, cuja elevação ultrapasse 50 m e declividade seja superior a 30 %, devam ser protegidos. O presente trabalho aplicou e avaliou o uso de modelagem em Sistema de Informações Geográficas para determinar automaticamente áreas de preservação permanente para topos de morros e montanhas, que dispensa a interferência de um operador na definição dos topos e bases dos morros. Para tanto, foi delimitada a área de APP em topo de morro e montanha, para as microrregiões Sudoeste Serrana, Litoral Norte e Extremo Norte do Estado do Espírito Santo em escala...

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...

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...

Density and relative frequency effects on competitive interactions and resource use in pea-barley intercrops
Provedor de dados: 21
Autores: Hauggaard-Nielsen, Henrik; Andersen, Mette Klindt; Joernsgaard, Bjarne; Jensen, Erik Steen.
Intercropping advantages may be influenced by both plant density and relative frequency of the intercrop components. In a field study barley (Hordeum vulgare L.) and pea (Pisum sativum L.) were sole cropped and intercropped at three densities, corresponding to i) half of the recommended, ii) the recommended and iii) twice the recommended plant density. Two intercrops combinations were included holding 1/3pea+2/3barley and 2/3pea+1/3barley relative to the sole crop densities employed.   For three growth intervals within the whole growing period, the relative performance and interactions between the two crops were assessed using the Relative Efficiency Index (REIc). The relative performance of the two species varied over the growing season and was influenced...

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...

Deposition of C and N in the soil from legume-based cover crops – quantification and mineralization.
Provedor de dados: 21
Autores: De Notaris, Chiara; Rasmussen, Jim; Sørensen, Peter; Olesen, Jørgen E.
Legume-based cover crops (CC) provide a wide range of ecosystem services, including nitrate leaching reduction, N fertilizer and soil C sequestration effects. However, the scarcity of information on belowground C and N increases the uncertainty on the magnitude of these effects. With the present study, we quantified soil C and N deposition from legume-based CC (two pure legumes and two mixtures) grown under field conditions, in Denmark. To do so, we labeled CC plants with 13C (CO2) and 15N (leaf-labeling) throughout their growing period, by following a frequent multiple-pulse labeling scheme. Then, we incubated labeled CC roots and soil to investigate C and N mineralization. Cover crops with red clover produced about 2.7 Mg ha-1 aboveground biomass, and...

Autores: Hammershoj, Marianne; Kidmose, Ulla; Steenfeldt, Sanna.
BACKGROUND: Supplying egg-laying hens with different forage materials may influence egg production and quality. The aim  of this study was to examine the short-term effects of standard feed plus 70 g day−1 per hen of three coloured carrot varieties (orange, yellow and purple) as forage material in comparison with a standard feed control on egg production, egg yolk colour and deposition of carotenoids in the yolk.  RESULTS: Carrot supplementation reduced feed intakes significantly, but not on a dry matter basis. Orange carrot treatment significantly reduced egg mass production, whereas yellow and purple carrot treatments did not differ from the control. Egg and yolk weights of all carrot-supplemented treatmentswere significantly lower than those of the...

In den Jahren 1994 bis 1998 hatte der biologische Landbau in Österreich bisher seine stärkste Entwicklung. Die frühe Verankerung von Richtlinien für biologische Produkte pflanzlicher und tierischer Herkunft im österreichischen Lebensmittelbuch, die staatliche Förderung der Umstellung bzw. der Biobetriebe, günstige Bedingungen im Absatz durch den Einstieg der Supermarktketten, die Gründung einer Vermarktungsgesellschaft, eine aktive Verbandspolitik und der Ausbau der Beratung haben dazu beigetragen, dass Österreich in Europa den höchsten Anteil an Biobetrieben erreichte.

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.

Autores: Mäder, Paul; Alföldi, Thomas; Niggli, Urs; Besson, Jean‐Marc; Dubois, David.
Der grosse Spardruck zwingt die Agrarforschungsinstitutionen weltweit, haushälterisch mit ihren Mitteln umzugehen. Die Forschungsschwerpunkte werden deshalb vor allem auf Themengebiete und Versuchsanstellungen gesetzt, in denen Resultate kurzfristig erwartet werden können und welche keine teuren Feldversuche benötigen. Ein Hauptziel moderner agrarwissenschaftlicher Forschung ist jedoch die Entwicklung nachhaltiger Produktionssysteme, die sich nur bedingt in kurzfristig angelegten Versuchen abklären lässt. Die Sicherung einer ausreichenden Nahrungsmittelerzeugung von hoher Qualität, ein haushälterischer Umgang mit nicht erneuerbaren Ressourcen (Düngemittel, Energie) sowie die Erhaltung der Bodenfruchtbarkeit und einer hohen Biodiversität sind wichtige...

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...

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...

Climate change models predict reduced summer precipitations for most European countries, including more frequent and extreme summer droughts. Rainout-shelters which intercept part of the natural precipitation provide an effective tool to investigate effects of different precipitation levels on biodiversity and ecosystem functioning. In this study, we evaluate and describe in detail a fixed-location rainout shelter (2.5×2.5m) with partial interception of natural rainfall. We provide a complete parts list, a construction manual and detailed CAD drawings allowing to rebuild and use these shelters for rainfall manipulation studies. In addition, we describe a rainout-shelter control treatment giving the possibility to quantify and account for potential shelter...

Design and multicriteria evaluation of regionalized test cases in organic crops without animal production
Provedor de dados: 21
Autores: Garnier, J.F.; Fontaine, Laurence; Lubac, Stanislas; Bouviala, M.
What are the performances of different stockless organic crops systems? And more specifically, are there rotations more efficient than other for economic, technical and / or environmental criteria? This work aims to present the method of co-construction of simulated cases for an evaluation of economic, environmental and technical performances, at rotation and production system scale. Fifteen «test cases» have been defined in the partner regions of CASDAR projects ROTAB and ProtéAB and evaluated with a set of quantitative and non-aggregated indicators (tool Systerre ®). The results provided many references at different scales. In the current context, profitability was ensured for all cases studied, but the production environment had a major impact on the...

Autores: Pfiffner, Lukas; Cahenzli, Fabian; Steinemann, Beatrice; Jamar, Laurent; Chor Bjørn, Mona; Porcel, Mario; Tasin, Marco; Telfser, Josef; Kelderer, Markus; Sigsgaard, Lene.
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...

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...

Det sværeste ved hvidkløver er afpudsningen
Provedor de dados: 21
Autores: Boelt, B.
Arealet med hvidkløver til frø var 3853 ha i 2004, hvilket er det største areal siden 1978, og generelt er udviklingen af de danske areal positiv. Følgerne af den afkoblede EU-støtte forventes at være neutral for hvidkløverfrøproduktionens vedkommende. Hos vores største konkurrent, New Zealand, har en øget mælkeproduktion medført en vigende frøproduktion af hvidkløver. Den new zealandske mælkeindustri har stor succes med eksport af tørmælk til Asien, og mælkeproducenterne presser planteavlerne i området Canterbury Plains, hvor hovedparten af New Zealands frøproduktion er placeret. New Zealand er dog fortsat verdens største producent af hvidkløverfrø. En del af produktionen er i øjeblikket under udflytning til Australien.

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....

Autores: Hecht, Mirco; Oehen, Bernadette; Schulze, Jürg; Brodmann, Peter; Bagutti, Claudia.
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...

Determinants of consumer acceptance of alternatives to piglet castration without anaesthesia - a review
Provedor de dados: 21
Autores: Heid, Astrid; Hamm, Ulrich.
In order to prevent the occurrence of boar taint, almost all male piglets are routinely castrated in Europe. Usually, this surgical intervention is carried out without the use of anaesthesia or analgesia. Recently, animal welfare concerns over this practice have been raised and efforts are made to ban surgical castration of piglets without anaesthesia. Therefore, it is necessary to find alternatives to piglet castration without anaesthesia.   An important factor for the implementation of possible alternatives is consumers’ acceptance of and willingness to pay for pork which was produced using these alternatives. Existing research on this topic mainly focused on consumer reactions to meat form entire male pigs. Only a few studies analysed consumer...

Provedor de dados: 21
Autores: Mallia, S.; Piccinali, P.; Rehberger, B.; Badertscher, R.; Escher, F.; Schlichtherle-Cerny, H.
The oxidative stability of butter enriched with unsaturated fatty acids and conjugated linoleic acids (UFA/CLA butter) was evaluated by chemical, sensory and microbiological analyses during 8 weeks of storage at 6 °C and compared with that of conventional butter. The odour-active compounds were analyzed by gas chromatography–mass spectrometry combined with olfactometry, using solid phase microextraction.  Olfactometric analysis showed that both, fresh UFA/CLA butter and fresh conventional butter had similar aroma profiles. After 6–8 weeks of storage, UFA/CLA butter showed stronger fatty (butanoic and 3-methyl butanoic acid), metallic [(E,E)-2,4-nonadienal], green [(E)-2-hexenol] and creamy (2-pentanone) notes compared with the conventional samples.

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...

Development and Daily Management of an Explicit Strategy of Nonuse of Antimicrobial Drugs in Twelve Danish Organic Dairy Herds
Provedor de dados: 21
Autores: Vaarst, M.; Bennedsgaard, T.W.; Klaas, I.C.; Nissen, T.B.; Thamsborg, S.M.; Østergaard, S.
Promotion of animal health and well-being at the individual animal and herd level is an important goal in organic farming. At the same time, chemical products affecting the natural balance among living organisms are prohibited in all areas of the organic farm. From an animal welfare point of view, however, no animal must suffer. Therefore, veterinary drugs are allowed under the European Union’s regulations for organic farming, despite the fact that they are powerful cell toxins affecting both pathogenic and necessary bacteria, and as such in organic terminology, are regarded as “chemical” or “artificial” products. In this article, we present and discuss interviews with 12 Danish organic dairy producers who claim that minimized use or nonuse of...

Development and structuring of the sector of full field organic vegetables in cereal zones
Provedor de dados: 21
Autores: Perret, C.; Béliard, E.; Rigault, A.
The organic vegetable consumption shows a progress that proved to be steady over years. Nevertheless, the offer of organic vegetables remains insufficient. The CasDar program dedicated to organic field vegetables, 2010-2013, aimed at studying the conditions for the development of large-scale production, by technical answers, and by contributing to the organization of the sector. This action, that concerned six regions of the North and the Central France, was led by players of the sector, producers, wholesalers, transformers, distributors. This favored a shared analysis of strengths and weaknesses of the sector. In a second step, the partners developed tools, to meet the identified stakes, that can be used in the zones of production of full field vegetables...

Development and survival of Ascaris suum eggs in deep  litter of pigs
Provedor de dados: 21
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...

Development of a Management Tool to Indicate the Environmental Impact of Organic Viticulture
Provedor de dados: 21
Autores: Fragoulis, Georgios; Trevisan, Marco; di Guardo, Andrea; Scorce, Andrea; van der Meer, Markus; Weibel, Franco; Capri, Ettore.
Organic viticulture is an important part of the European Union organic farming sector, and, according to the most recent surveys, 1.5% of European Union wine originates from organic farms, with an upward trend. This paper describes an environmental impact of an organic viticulture indicator (EIOVI) that can be reliably used in the management of organic vineyards. The EIOVI can be used as a decision support system for farmers and other property managers by evaluating the potential ecological impact of their choices, thus optimizing management options. The tool allows the simulation of vineyard management based on six agricultural and ecological modules. The EIOVI is a fuzzy expert system that calculates the relationship between the modules on the basis of a...

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...

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...

Development of locally-adapted faba bean cultivars for organic conditions in Germany through a participatory breeding approach
Provedor de dados: 21
Autores: Ghaouti, Linmiae; Vogt-Kaute, Werner; Link, Wolfgang.
Organic farming requires cultivars that are specifically adapted to this low input cropping system. Hence, organic farmers and scientists joined in a participatory breeding approach to develop region-specific genotypes of spring faba bean for organic conditions in Germany. A set of 49 genotypes with contrasting degrees of heterozygosity and heterogeneity was used in field trials across five locations in Germany during 3 years 2004, 2005 and 2006. The material involved 18 inbred lines, their 18 polycross progenies, one blend of inbred lines, one blend of polycross progenies, one blend of hybrids and ten checks. Inbred lines are uniform, thus giving the option to be specifically adapted; whereas the polycross progenies and synthetics (Syn-1; predicted from...

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....

Development prospects and challenges for organic farming in the Midi-Pyrénées region of France
Provedor de dados: 21
Autores: MONDY, B.; TERRIEUX, A.; GAFSI, M.; HEMPTINNE, J.L.
With 67,000 ha and 1,200 organic farms (OF), the Midi-Pyrénées region is the biggest agricultural area in France and second only to the Pays de Loire region in number of farms.   Organic farming has developed rapidly over the past 15 years due to the steep increase in the demand for organic products. However, this was not always the case due to several factors linked to technical difficulties: market access, wide use of imports, a trend towards industrialisation, difficulties in mastering techniques, particularly for the production of high quality durum wheat, the ineffectiveness or absence of organisations intended to help producers, etc. As a result, the Midi-Pyrénées Regional Council, which had supported organic farming for a long time, sponsored...

The need for increased sustainability of performance in cereal varieties, particularly in organic agriculture (OA), is limited by the lack of varieties adapted to organic conditions. Here, the needs for breeding are reviewed in the context of three major marketing types, global, regional, local, in European OA. Currently, the effort is determined, partly, by the outcomes from trials that compare varieties under OA and CA (conventional agriculture) conditions. The differences are sufficiently large and important to warrant an increase in appropriate breeding. The wide range of environments within OA and between years, underlines the need to try to select for specific adaptation in target environments. The difficulty of doing so can be helped by...

Greenhouse gas (GHG) emissions from agriculture are a significant contributor to total Danish emissions. Consequently, much effort is currently given to the exploration of potential strategies to reduce agricultural   emissions. This paper presents results from a study estimating agricultural GHG emissions in the form of methane, nitrous oxide and carbon dioxide (including carbon sources and sinks, and the impact of energy consumption/bioenergy production) from Danish agriculture in the years 1990-2010. An analysis of possible measures to reduce the GHG emissions indicated that a 50-70% reduction of agricultural emissions by 2050 relative to 1990 is achievable, including mitigation measures in relation to the handling of manure and fertilisers,...

Die Bedeutung des ökologischen Landbaues für die Gesellschaft
Provedor de dados: 21
Autores: Oppermann, Rainer.
Anlässlich der gemeinsamen Sitzung von Kuratorium und Vorstand der Agrarsozialen Gesellschaft e.V. am 21. März 2002 referierte Dr. Rainer Oppermann zur Bedeutung des Ökologischen Landbaus für die Gesellschaft. Seiner Ansicht nach ist es keine Frage, dass der ökologische Landbau eine feste Größe in der Landwirtschaft ist und dass die Entwicklung eines Wirtschaftsbereichs, der im Jahr 1980 449 Betriebe zählte und heute bei rund 15000 Betrieben angekommen sein dürfte, insgesamt als Erfolgsgeschichte zu bezeichnen ist.

Die Bestimmungsgründe der räumlichen Verteilung des ökologischen Landbaus in Deutschland
Provedor de dados: 21
Autores: Bichler, Barbara; Lippert, Christian; Häring, Anna Maria; Dabbert, Stephan.
Der ökologische Landbau ist in Deutschland räumlich sehr heterogen verteilt und lässt regionale Schwerpunkte erkennen. Generell hängt die räumliche Verteilung des ökologischen Landbaus von mehreren Faktoren ab. So weisen beispielsweise die Standortfaktoren der Betriebe regionale Unterschiede auf, die sich auf die räumliche Verteilung des ökologischen Landbaus auswirken können. Zu den Standortfaktoren landwirtschaftlicher Betriebe zählt auch die räumliche Nachbarschaft.   Im Rahmen dieser Studie wurden die Faktoren, die tendenziell die räumliche Verteilung des ökologischen Landbaus in Deutschland beeinflussen, in vier Kategorien eingeteilt. Es sind dies: natürliche Bestimmungsfaktoren, betriebliche Bestimmungsfaktoren, sozio-ökonomische Bestimmungsfaktoren...

Autores: Stolze, Matthias; Sanders, Jürn.
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.

Die Kirschessigfliege – ein neuer Schädling im Weichobstanbau
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.

Die Landwirtschaft als Medienthema – Inhaltsanalyse Schweizer Zeitungen und Fernsehsendungen zwischen 1996 und 2006
Provedor de dados: 21
Autores: Alföldi, Thomas; Tutkun-Tikir, Aysel.
Mit dem anhaltenden Strukturwandel nehmen persönliche Kontakte zwischen landwirtschaftlicher und nicht-landwirtschaftlicher Bevölkerung ab. Damit steigt die Bedeutung der Medien bei der Meinungsbildung zu landwirtschaftlichen Themen. In der vorliegenden Arbeit wird deshalb die Berichterstattung über die Landwirtschaft in ausgewählten Schweizer Print- und TV-Medien inhaltsanalytisch untersucht. Die Ergebnisse zeigen, dass produktionsorientierte Themen überwiegend positiv, agrarpolitische Themen hingegen deutlich kritischer dargestellt werden. Im Untersuchungszeitraum werden landwirtschaftliche Themen vermehrt im regionalen Kontext präsentiert, stärker personalisiert und zunehmend positiv dargestellt. Insgesamt kann von einer zunehmend positiven...

Die Öko-Zertifizierung in Deutschland aus Sicht der  Produzenten: Handlungsvorschläge zur politischen  Weiterentwicklung
Provedor de dados: 21
Autores: Schulze, Holger; Jahn, Gabriele; Neuendorff, Jochen; Spiller, Achim.
Um den veränderten Anforderungen des ökologischen Marktes gerecht zu werden (z.B. zunehmende Internationalisierung) hat sich der Agrarrat im letzen Jahr (28. Juni 2007) auf eine neue Verordnung zur Produktion und Kennzeichnung von ökologischen Produkten verständigt (VO (EG) Nr. 834/2007).  Die Öko-Kontrolle soll zukünftig europaweit durch staatliche Behörden durchgeführt werden, die nur „genau beschriebene Aufgaben“ an private Öko-Kontrollstellen übertragen dürfen. Insgesamt kann die Neuregelung als deutlicher Schritt zu einem vermehrt staatlichen und formalen Kontrollsystem betrachtet werden. Dieser institutionelle Wechsel bildet die Ausgangsbasis dieses Beitrages, der auf eine Befragung von 126 deutschen Öko-Landwirten beruht.  Im Mittelpunkt der...

Die Preise von Bio-Lebensmitteln als Hürde bei der Agrar- und Konsumwende [Prices for organic food as an obstacle for a new agricultural and consumer policy]
Provedor de dados: 21
Autores: Koerber, Karl von; Kretschmer, Jürgen.
Die Verbraucherpreise für Lebensmittel aus ökologischer Landwirtschaft liegen in der Regel über denen für konventionell erzeugte. Die höheren Preise von Öko-Erzeugnissen stellen für viele Verbraucher eine Kaufbarriere dar. Eine Ausweitung der ökologischen Landwirtschaft auf 20 Prozent innerhalb der nächsten zehn Jahre ist jedoch erklärtes politisches Ziel der deutschen Bundesregierung. Die Mehrkosten für Öko-Produkte sind in diesem Zusammenhang erklärungsbedürftig, um die Konsumenten zu einem vermehrten Kauf zu motivieren. In diesem Beitrag wird die Preisbildung von konventionell und ökologisch erzeugten Produkten vorgestellt. Dabei werden nicht nur die Kosten selbst, sondern auch weitergehende Qualitätsaspekte von Lebensmitteln aus ökologischer und...

Bei den Hauptfunktionen der Landwirtschaft zeichnet sich der Ökologische Landbau durch Nachteile in der Nahrungsmittelversorgung, Unsicherheiten in der Existenzsicherung von Betrieben und Vorteile im Umweltschutz aus. Durchschlagende Verschlechterungen in der Nahrungsversorgung treten erst bei Flächenanteilen über 20% auf Dagegen reagiert der Gewinn von Betrieben sehr sensibel auf Veränderungen im Preisniveau. Bei der Förderung des Ökologischen Landbaus sollte der Staat zu Verfahren greifen, die größere und länger anhaltende Angebotsüberhänge vermeiden.  Beachtliche und vielfältige Vorteile hat der Ökologische Landbau im Umweltschutz aufzuweisen. Die positiven Umweltwirkungen sind jedoch nicht gleichmäßig in allen Betrieben vorhanden.

Provedor de dados: 21
Autores: Ingerslev, Hans-Christian; Strube, M. Lenz; Jørgensen, Louise von Gersdorff; Dalsgaard, Inger; Boye, Mette; Madsen, Lone.
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...

Dietary citrus pulp improves protein stability in lamb meat stored under aerobic conditions
Provedor de dados: 21
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...

Agriculture of the Czech Republic has features of submonate and montane agriculture. More than half of the surface of the Czech Republic are less favourable areas (LFA). Active state support of farming focused on the extensive production and maintenance of the countryside and the other environmental services is the crucial point of a successful development of competitive and economical (from the point of view of the environment) production in LFA. Organic farming is carried out on the area of 6 % of the surface of agricultural land, most of agricultural land is worked with conventional methods of farming. In the Czech Republic there are significant differences between structure of the organic and conventional farming, especially in the share of arable land...

Hulled wheat species (einkorn, emmer, spelt) are presumed to be an alternative to bread wheat in organic agriculture since the yield penalty is less pronounced under organic farming and generally higher prices can be achieved for specialty grains. The present study analyzed differences between wheat species with respect to biomass production, harvest index, grain yield and protein content. Spring hulled wheat genetic resources and bread wheat check cultivars were grown in organic field trials in the Czech Republic and Austria between 2010 and 2012. Generally, hulled wheat species were inferior in grain yield and distribution of assimilates to the grain compared to modern bread wheat. Biomass production of some emmer and spelt landraces was similar to bread...

Resistance to anthelmintics in populations of gastrointestinal nematodes is a major concern in small ruminants. One solution  to limit the spread of anthelmintic resistance is to apply treatments selectively by targeting the most susceptible animals within  a flock. In dairy goats, previous studies have shown that, within a flock, goats in first lactation and those with high level of milk  production were highly receptive to nematode infections. These results provided the rationale for targeted treatments. In dairy  ewes, such epidemiological information on possible factors modulating the susceptibility to parasitism were still lacking. The  objective of the current study was therefore to examine differences in the level of parasite infection and in the...

Autores: Aertsens, Joris; Mondelaers, Koen; Van Huylenbroeck, Guido.
Abstract: Purpose – The organic product market can be considered as an emerging market. Since the 1990s it has experienced rapid growth, and supermarket chains have become the sales channel with the largest market share and are the main driver for further growth. However, different supermarket retail groups have very different strategies concerning the marketing of organic products. The purpose of this paper is to gain insight into the different strategies of retailers who are active in the organic product market and to explain the drivers which may underlie them.     Design/methodology/approach – The strategies of the three most important Belgian retailers that market organic products, and in particular organic beef, are analyzed. Data were collected...

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...

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...

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.

Autores: Denver, Sigrid; Christensen, Tove.
This study investigates the relationship between how consumers prefer to group different varieties of organic and conventional products and their preferences for organic food. Using a web-based questionnaire, 849 Danish respondents were asked to group the content of a virtual basket of organic and non-organic fruit and vegetables into two smaller baskets. Almost half of the consumers placed the products according to whether they were organic or not. These consumers were found to have a significantly higher confidence in the benefits of organic products and stated a significantly higher organic consumption than consumers who placed fruit in one basket and vegetables in the other. Differences in preferences for organic food between the two categories of...

Differentiation of organically and conventionally produced  milk by stable isotope and fatty acid analysis
Provedor de dados: 21
Autores: Molkentin, Joachim; Giesemann, Anette.
Increasing sales of organic milk mean intensified tests for authenticity are required. In addition to comprehensive documentation, analytical methods to identify organic milk, and thus to differentiate it from conventional milk, are needed for consumer protection. Because the composition of milk is fundamentally dependent on the feeding of the cows, thirty-five samples from both production systems in Germany, including farm and retail milk, were collected within 12 months, to reflect seasonal variation, and appropriate properties were analysed. Fatty acid analysis enabled organic and conventional milk to be completely distinguished, because of the higher α-linolenic acid (C18:3ω3) and eicosapentaenoic acid (C20:5ω3) content of the former. Organic milk fat...

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...

Digging for the roots of urban gardening behaviours
Provedor de dados: 21
Autores: Lewis, Olivia; Home, Robert; Kizos, Thanasis.
Urban green spaces make a significant contribution to the social and ecological environment in cities, and the decisions of green space managers have direct impacts at both local and city scales. However most studies have focussed on public green spaces, despite privately managed gardens collectively forming a large proportion of urban green. The aim of this qualitative paper is to understand why people become involved in gardening and why they choose environmentally friendly gardening practices. We conducted semi-structured interviews with 23 gardeners in Lausanne, Switzerland and analysed them according to their content. Three major themes emerged as motivations for gardening: wellbeing, social aspects, and outputs (both tangible, such as food, and...

Digital image analysis offers new possibilities in weed harrowing research
Provedor de dados: 21
Autores: Rasmussen, Jesper; Nørremark, Michael.
Two field experiments were carried out in winter wheat to determine the optimal intensity and timing of weed harrowing. Each experiment was designed to create a series of intensities by increasing the number of passes at varying growth stages. Visual assessments and digital image processing were used to assess crop soil cover associated with weed harrowing. The study showed that winter wheat responded differently to weed harrowing at different growth stages. In autumn, the crop was severely damaged due to high degrees of crop soil cover and poor recovery resulting in crop yield losses in the range of 7 % to 22 %. In early spring, the crop showed some variability in the ability to recover from soil cover. The best results in spring were obtained at growth...

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...

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,...

Urban gardens are popular green spaces that have the potential to provide essential ecosystem services, support human well-being, and at the same time foster biodiversity in cities. We investigated the impact of gardening activities on five soil functions and the relationship between plant (600 spp.) and soil fauna (earthworms: 18 spp., springtails: 39 spp.) in 85 urban gardens (170 sites) across the city of Zurich (Switzerland). Our results suggest that high plant diversity in gardens had a positive effect on soil fauna and soil multifunctionality, and that garden management intensity decreased plant diversity. Indices of biological activity in soil, such as organic and microbial carbon and bacterial abundance, showed a direct positive effect on soil...

There is alack of research into why consumers value process characteristics. In this study, we test the hypothesis that the impact of process characteristics such as organic and free-range on consumers’ choices of food products is at least partly mediated through expected eating quality or taste expectations. In other words, the process characteristics partly function as cues to (eating)quality.

Autores: Lukashyk, P.; Berg, M.; Köpke, U.
Die Rauhaarige Wicke (Vicia hirsuta) kann in konkurrenzschwachen Wintergetreidebeständen des Organischen Landbaus in hoher Dichte und Masse auftreten. Die Folge sind Ertrags- und Qualitätsverluste sowie Ernteerschwernisse. Informationen zur erfolgversprechenden Regulierung von Vicia hirsuta fehlen bislang weitgehend. In faktoriellen Feldversuchen zu Winterweizen und Winterroggen wurden das Verätzen der Wicken durch Einsatz von Kainit, die thermische Kontrolle sowie die mechanische Kontrolle (Striegel) in frühen und späten Entwicklungsstadien geprüft. Erfasst wurden Anzahl und Deckungsgrad der Wicken, die Schäden an der Kulturpflanze, Ertragsparameter (Kulturpflanze) und die Samenproduktion der Wicken.  Die Ergebnisse aus den Versuchsjahren 2002 und 2003...

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...

Discrimination of conventional and organic white cabbage from a long-term field trial study using untargeted LC-MS-based metabolomics
Provedor de dados: 21
Autores: Mie, Axel; Laursen, Kristian Holst; Aberg, K. Magnus; Forshed, Jenny; Lindahl, Anna; Thorup-Kristensen, Kristian; Olsson, Marie; Knuthsen, Pia; Larsen, Erik Huusfeldt; Husted, Søren.
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...

Discrimination of milk carbon footprints from different dairy farms when using IPCC Tier 1 methodology for calculation of GHG emissions from managed soils
Provedor de dados: 21
Autores: Schueler, Maximilian; Hansen, Sissel; Paulsen, Hans Marten.
Quantification of the environmental performance of dairy farms should allow comparisons between farms. We assess whether IPCC Tier 1 methodology for emissions from soil management is sufficiently precise to analyse and differentiate the carbon footprint of milk production between practical dairy farms and whether we can correctly identify which farms have the lowest and the highest GHG emissions per product unit, respectively.  We used data from 20 Norwegian dairy farms which are very similar in structure, but differ in organic/non-organic management and the share of peat soil of their farmland.We assessed the uncertainty of the carbon footprint by running Monte Carlo simulations with the uncertainty ranges given in Tier 1 of the IPCC guidelines. The...

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...

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...

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...

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)...

Distribution and use of grasslands in the Czech Republic and biodiversity of invertebrates
Provedor de dados: 21
Autores: Moudry, Jan (Jr.); Bohac, Jaroslav; Konvalina, Petr; Moudry, Jan; Kolarova, Pavlina.
In the Czech Republic the major focus of organic farming lies in permanent grasslands management. Animal production is mostly focused on non-milk pasture beef-raising on almost the whole farm area. By contrast conventional farms do not grass sufficiently, even in areas with higher elevation. This fact is influenced by subvention programmes motivating farmers to fulfil the agroenvironmental function of agriculture using grassing, however there is no support for agriculture on arable land. Permanent grasslands are predominantly used for beef grazing. Large areas are harvested too, which affects biodiverzity. Grasslands utilized for pasture are rich in biodiversity which enhance ecosystem services. The effect of grassland management on the different taxa and...

Divergent selection on feather pecking behavior in laying hens has caused differences between lines in egg production, egg quality and feed efficiency
Provedor de dados: 21
Autores: Su, Guosheng; Kjaer, Jørgen B.; Sørensen, Poul.
The correlated changes in egg production, egg quality, and feed efficiency due to selection for or against feather pecking (FP) were investigated by analyzing the data from an experiment including two divergent selection lines and a control line. The experiment was conducted with hens at the age of 42 to 46 weeks (hatch 1) and 39 to 43 weeks (hatch 2) in the fifth generation of selection. Number of FP bouts per hour in low FP line (LP) was significantly lower than that in high FP line (HP) (0.38 vs. 2.01), and total plumage score in line LP was significantly better than that in line HP (16.9 vs. 11.6). During the four weeks, egg number and egg mass in line LP were significantly higher than those in line HP (24.4 vs. 18.3, and 1223 g vs. 1132 g).  On the...

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...

Autores: Konvalina, Petr; Moudry, Jan; Suchý, Karel; Capouchova, Ivana; Janovska, Dagmar.
Strong drought tolerance is an important objective in breeding new wheat varieties. We compared the drought tolerance of land races and modern varieties of various spring wheat forms. 13C discrimination (CID) indicated how significantly the tested wheat varieties were inclined to drought tolerance. CID is a trait related to stomatal closure and consequently an important component of the tolerance to drought. Samples were grown in České Budĕjovice (CZ), from 2009 to 2012. Twenty-three varieties, comprising einkorn, emmer, spelt, land races and control variety of bread wheat were grown and tested. Results have shown some varieties achieved low CID values (which meant they were more inclined to the drought tolerance). There were emmer and spelt varieties...

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...

New societal values call for the diversification of agriculture to fit contrasted environments. This process can be depicted by four models defined by two axes, a socio-economic axis (individual logic vs. collective governance), and an agro-ecological axis (analytical vs. systemic approaches). These models differ in: (i) their objectives (from improvement in yield to the empowerment of farmers), (ii) their specific expectations with respect to genotypes (from inherited genetic resources to varieties that represent genetic, ethical and social progress), and (iii) their representations of the environment (from a simple interaction between the bio-physical environment and crop management, to a complex interaction including the skills of stakeholders, outlets,...

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...

Do inspection practices in organic agriculture serve organic values? A case study from Finland
Provedor de dados: 21
Autores: Seppänen, Laura; Helenius, Juha.
In many European countries, organic agriculture has rapidly been transformed from a farmers' movement to an institutionalized part of agricultural policy. In certification, compliance with published organic standards is verified through annual inspections on farms.  In Finland, the role of advice in organic inspections has been the subject of debate. Two inspections are used here to show how the term organic was defined and what the role of advice in relation to compliance was.  Both compliance and advisory types of interaction between the inspector and the farmer were identified along an axis from “input substitution” to “system redesign.”  The findings illustrate the heterogeneity of the processes and definitions of the term organic in connection with...

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.

Do sown wildflower strips enhance the parasitism of lepidopteran pests in cabbage crops?
Provedor de dados: 21
Autores: Pfiffner, Lukas; Merkelbach, L.; Luka, Henryk.
We investigated the parasitism rates of cabbage lepidopteran pest in relation to presence or absence of adjacent sown, species rich wildflower strips at two sites on farms in the region Grosses Moos, Switzerland. Three treatments have been tested: (1) cabbage adjacent to a wildflower strip, (2) cabbage near to a wildflower strip (&gt;10 m up to 90 m), and (3 = control) cabbage without wildflower strip or any other semi-natural habitats nearby. Caterpillars and eggs of Mamestra brassicae, Pieris rapae, and Plutella xylostella (only larvae) have been sampled weekly in the unsprayed cabbage crops at 6 dates (cauliflower) and 9 dates (red cabbage). The parasitism rate of each pest species and its stage of development was recorded.  Caterpillars of M. brassicae...

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...

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...

Does certified organic farming reduce greenhouse gas emissions from agricultural production? Comment on the McGee study
Provedor de dados: 21
Autores: Müller, Adrian; Aguilera, Eduardo; Skinner, Colin; Gattinger, Andreas.
A recent study by McGee (Agriculture and Human Values, 32, 255–263, 2015) from the University of Oregon has led to discussions in international media and on the web. This study addresses an interesting question and applies advanced statistics for its analysis. However, we identify several methodological flaws that invalidate the results. First, McGee tests a hypothesis that does not correspond to his main question and which does not allow McGee to derive the conclusions that are drawn in his paper and reported in the media coverage. Second, the data used are not adequate for the analysis because: i) the dependent variable does not reflect the greenhouse gas emissions characteristics of organic agriculture (e.g. different emission factors in organic and...

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...

Does instrumentalization of “organic farming” lead to enhancement or dissolution? - A case study of the local dissemination processes of organic farming
Provedor de dados: 21
Autores: Noe, Egon.
The dissemination of “organic farming” is a topic of great attention as a measure to environmental regulation, high value food production, etc. and the Danish case of organic agriculture is generally regarded as a success story. The prevailing strategy of the Danish organic movement has been to mobilise non-organic actors in the dissemination of the ‘organic mode of farming’. A strategy that is embedded in a dogmatic belief that the ‘internal conversion’ in terms of values, ideas and thinking almost automatically will follow the ‘external conversion’ into the ‘organic mode’ of farming according to the rules. In this paper farmers’ network-strategy to disseminate organic farming is explored through a longitudinal case study within a local area with a high...

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...

Changes in agriculture might drive changes in biodiversity and are expected to have just as serious an effect as climate change. These changes are results of complex changes in land-use as well as land management, intensification of management and structural developments in agriculture. In this review we present results of a recent research project (ICROFS 2013) focusing on organic farming and biodiversity in Denmark and relate the results to international studies that focus on drivers of biodiversity in the agricultural landscape. The project was organized under five major themes, forming the main sections of the present review paper: Impact on i) plant biodiversity  ii) insect and food-webs in cereal fields, iii) small mammals, iv) natural genetic...

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...

Does organic livestock husbandry uses less energy and produces less greenhouse gas than conventional husbandry? Analysis in   lactating sheep farms
Provedor de dados: 21
Autores: Dakpo, Hervé; LAIGNEL, G; Roulenc, M.; BENOIT, M.
We have undertaken in this work an evaluation of the greenhouse gas (GHG) emissions and the Non-Renewable Energy (NRE) consumption on a sample of 1250 farms-years, operating in sheep meat production, in either organic (OA) or conventional (CA) agriculture, over the period 1987 to 2012, based on the Life Cycle Assessment (LCA) method. There was no significant difference for NRE consumption (79.6 MJ in OA and 79.7 MJ in CA, per kg of carcass); indeed the gains in OA thanks to a lower use of chemical fertilizers and purchase of lesser concentrates feed were offset by the higher level of mechanization (here fuels and equipment). For GHG emissions, we found a significant difference of 5% beneficial to organic production systems (31.1 vs. 32.7 kg CO2 eq/kg...

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....

Does scale matter? Cost-effectiviness of agricultural nutrient abatement when target level varies
Provedor de dados: 21
Autores: Iho, Antti.
Agriculture is facing stringent requirements for nutrient loss reductions. These reductions should be done cost-effectively. For instance, the European Water Framework Directive (WFD) emphasizes cost-effectiveness in reaching good water status in European river basins by 2015. River Basin Management Plans specify the eventual reduction targets, which will differ between the basins. These differences have implications on cost-effectiveness assessments: changing the level of total abatement changes the relative shares of measures in the cost-effective allocation. In this paper we develop a model which determines the cost-effective allocation of three alternative measures to reduce phosphorus loss from fields. The model allows for comparisons with cost and...

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.

Drivers of organic carbon allocation in a temperate slope-floodplain catena under agricultural use
Provedor de dados: 21
Autores: Mayer, Stefanie; Schwindt, Daniel; Steffens, Markus; Völkel, Jörg; Kögel-Knabner, Ingrid.
The distribution of soil organic carbon (OC) in the landscape shows high variability between landform positions.  Soils in depositional sites are characterized by a highly diverse vertical structure and can contain significant amounts of OC over the whole soil profile. However, anthropogenic modifications of the landscape such as land use and artificial drainage can significantly alter the OC balance in a catchment. Here, we analyse the spatial distribution of OC stocks along an agriculturally used catena in a catchment, tributary to the Danube River in the Bavarian Forest in Southern Germany. The combination of geomorphic aspects with highly detailed soil data based on 16 soil profiles along a catena allowed us to closely examine the relationship between...

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. Dette indlæg beskriver drivkræfter bag omlægning til økologisk jordbrug og tilbagelægning til konventionel drift på baggrund af to...

Drosophila suzukii: ein neuer Schädling im Weichobstanbau
Provedor de dados: 21
Autores: Daniel, Claudia.
Die Kirschessigfliege Drosophila suzukii wurde 2008 nach Europa eingeschleppt. Im Mittelmeerraum wurden 2011 starke Schäden vermeldet. In diesem Jahr ist mit Schäden auch nördlich der Alpen zu rechnen. Die Fliegen befallen alles Weichobst (Beeren, Kirschen, Trauben), sowie viele wilde Pflanzen. In diesem Jahr sollten alle sensiblen Kulturen mit Apfelessig-Fallen überwacht werden. Zur Befallsvorbeugung werden der Einsatz von engmaschigen Netzen (0.8 mm), sowie eine frühzeitige, vollständige Ernte und das Vernichten befallener Früchte empfohlen.

Drosophila suzukii: importantes différences dans la sensibilité des cépages de vigne.
Provedor de dados: 21
Autores: Kehrli, Patrik; Cahenzli, Fabian; Daniel, Claudia; Linder, Christian.
Même si la présence de la drosophile du cerisier (Drosophila suzukii) dans les vignobles suisses a provoqué une grande inquiétude auprès des viticulteurs en 2014, les expériences acquises ces deux dernières années montrent que la vigne doit être considérée comme une plante hôte secondaire. Malgré cela, des oeufs peuvent être pondus dans les baies de divers cépages. Avec l’aide des services cantonaux, nous avons échantillonné plus de 90 000 baies dans 500 parcelles en 2015, ainsi que 150 000 baies dans 600 parcelles en 2016. L’analyse de ces données montre que la sensibilité du raisin augmente avec la maturation, que les cépages rouges Acolon, Cabernet Dorsa, Cornalin, Divico, Dornfelder, Dunkelfelder, Galotta, Garanoir, Humagne rouge, Mara, Regent et Syrah...

Drought Tolerance and Perennial Weed Management
Provedor de dados: 21
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...

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...

Dry matter and fibre yields, and the fibre characteristics of five nettle clones (Urtica dioica L.) organically grown in Austria for potential textile use
Provedor de dados: 21
Autores: Hartl, A.; Vogl, C.R.
The aim of the field trial was to quantifiy yield, fibre content and fibre quality of 5 fibre nettle clones cultivated according to the principles of organic farming. The field trial started in 1997 and was organized in a randomised block design with 4 replications per clone. The field trial was situated in Neulengbach, Lower Austria. Since fibre nettle does not provide sufficient yields in the first cultivation year, the harvest of the second and third cultivation year (1998 respectively 1999) was used for calculation of yield per hectar and for the analysis of fibre content and quality.   The dry matter yield (stalks) of the 5 nettle clones in the second cultivation year (1998) lies between 2,3 – 4,7 t/ha. Clone 1 and Clone 7 achieve the highest yields....

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...

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.

Dynamics of a pasture soil microbial community after deposition of cattle urine amended with [13C]urea
Provedor de dados: 21
Autores: Petersen, Søren O.; Roslev, Peter; Bol, Roland.
Within grazed pastures, urine patches are hot-spots of nitrogen turnover since dietary N surpluses are excreted mainly as urea in the urine. This short-term experiment investigated 13C uptake in microbial lipids after simulated deposition of cattle urine at 10.0 and 17.1 g urea-C m-2. Confined field plots without or with cattle urine amendment were sampled after 4 and 14 days, and soil from 0-5 and 10-20 cm depth was analyzed for content and composition of phospholipid fatty acids (PLFAs), and for the distribution of urea-derived 13C among individual PLFAs. Carbon dioxide emissions were quantified and the contributions derived from urea assessed. Initial changes in PLFA composition were greater at the lower level of urea, as revealed by a principal...

Dynamics of mineral nitrogen, water-soluble carbon and potential nitrification in band-steamed arable soil
Provedor de dados: 21
Autores: Elsgaard, Lars.
Steaming of narrow soil bands prior to sowing is a new technique that reduces the need for intra-row weeding in herbicide-free row crops. However, the steam treatment may eliminate both weed seeds and non-target soil organisms, thereby affecting the nutrient cycling in the soil. This study tested the effect of band-steaming on N and C dynamics in a sandy loam soil that was steamed in situ to  maximal temperatures of 70–90°C using a prototype bandsteamer. Soil samples (0–5 cm depth) were collected during 90 days from band-steamed soil, undisturbed control soil, and control soil treated just mechanically with the bandsteamer. In the steamed soil, ammonium concentrations  increased from 1.1 to 20.3 μg NH4+-N g−1 dry weight  during 28 days. This coincided with...

The dynamics of nitrogen (N) in ryegrass intercropped with different forage species with regard to dry matter (DM) accumulation within an agroecological transition system was evaluated. Annual ryegrass was intercropped with black oats (RY + BO), white clover (RY + WC) and forage peanut (RY + FP). The experimental design was completely randomized, with three replications. The study applied the N dilution model for plant tissue which comparatively uses modifiable factors of the environment at optimal levels. The model shows decline in N concentration due to the DM accumulation of temperate grass pastures. Data were compared to model by the root mean square deviation analysis. Dilution coefficient (β), used in all pasture samples, was lower than -0.60....

Dynamics of policy networks. The case of organic farming policy in the Czech Republic
Provedor de dados: 21
Autores: Moschitz, Heidrun; Hrabalova, Andrea; Stolze, Matthias.
To better understand the potential for successful and long-term establishment of environmental policy, the aim of this paper is to explore the network dynamics of a policy field that has become well established in the EU: organic farming. We look at the dynamics of the organic farming policy network in the Czech Republic over a period of ten years by applying a comparative formal network analysis. We focused in particular on the distribution of power between actors and how capacities of policy actors have evolved between 2004 (its year of accession to the EU) and 2014. We conclude that the organic farming policy network in the Czech Republic has been highly dynamic and has changed from one that was decidedly influenced by organic sector organizations to a...

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.

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...

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....

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...

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...

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...

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...

Eating quality of carrots (Daucus carota L.) grown in one conventional and three organic cropping systems over three years.
Provedor de dados: 21
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...

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...

Eco-efficiency and agricultural innovation systems in developing countries: Evidence from macro-level analysis
Provedor de dados: 21
Autores: Grovermann, Christian; Wossen, Tesfamicheal; Müller, Adrian; Nichterlein, Karin.
Agricultural innovation is an essential component in the transition to more sustainable and resilient farming systems across the world. Innovations generally emerge from collective intelligence and action, but innovation systems are often poorly understood. This study explores the properties of innovation systems and their contribution to increased eco-efficiency in agriculture. Using aggregate data and econometric methods, the eco-efficiency of 79 countries was computed and a range of factors relating to research, extension, business and policy was examined. Despite data limitations, the analysis produced some interesting insights. For instance public research spending has a positive significant effect for emerging economies, while no statistically...

The paper has two main objectives: (i) to assess the eco-efficiency of spring barley cultivation for malting in Denmark in a future changed climate (700 ppm [CO2] and +5 °C) through Life Cycle Assessment (LCA) and (ii) to compare alternative future cultivation scenarios, both excluding and including earlier sowing and cultivar selection as measures of adaptation to a changed climate. A baseline scenario describing the current spring barley cultivation in Denmark was defined, and the expected main deviations were identified (differences in pesticide treatment index, modifications in nitrate leaching and change in crop yield). The main input data originate from experiments, where spring barley cultivars were cultivated in a climate phytotron under controlled...

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...

Autores: Aviron, Stéphanie; Nitsch, Heike; Jeanneret, Philippe; Buholzer, Serge; Luka, Henryk; Pfiffner, Lukas; Pozzi, Stefano; Schüpbach, Beatrice; Walter, Thomas; Herzog, Felix.
In ecological cross compliance, farmers have to meet environmental standards in order to qualify for area-related direct payments. Because this is a strong financial incentive, cross compliance is a potentially powerful policy instrument. We monitored the effectiveness of cross compliance in promoting biodiversity on grassland and on arable land in Switzerland over 8 years. We observed measurable benefits for flora, butterflies, ground beetles, and spiders, in terms of species numbers and/or community composition. However, populations of threatened species showed no signs of benefit. While cross compliance has been in force in Switzerland for almost a decade, it has only recently been introduced in the neighbouring European Union. We argue that – provided...

Ecological divergence plays an important role in strong but complex reproductive isolation in campions (Silene)*
Provedor de dados: 21
Autores: Karrenberg, Sophie; Liu, Xiaodong; Hallander, Emelie; Favre, Adrien; Herforth-Rahmé, Joelle; Widmer, Alex.
New species arise through the evolution of reproductive barriers between formerly interbreeding lineages. Yet, comprehensive assessments of potential reproductive barriers, which are needed to make inferences on processes driving speciation, are only available for a limited number of systems. In this study, we estimated individual and cumulative strengths of seven prezygotic and six postzygotic reproductive barriers between the recently diverged taxa Silene dioica (L.) Clairv. and S. latifolia Poiret using both published and new data. A combination of multiple partial reproductive barriers resulted in near‐complete reproductive isolation between S. dioica and S. latifolia, consistent with earlier estimates of gene flow between the taxa. Extrinsic barriers...

Ecological Recycling Agriculture to Enhance Agro-Ecosystem Services in the Baltic Sea Region: Guidelines for Implementation
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...

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...

Autores: Hohmann, Pierre; Jones, E. Eirian; Hill, Robert A.; Stewart, Alison.
The plant health- and growth-promoting biological inoculant (bio-inoculant) Trichoderma hamatum LU592 was transformed with the constitutively expressed green fluorescent protein (gfp) and hygromycin B resistance (hph) genes to specifically monitor the isolate in the root system of Pinus radiata within a strong indigenous Trichoderma population. A modified dilution plating technique was developed to allow the determination of the mycelia proportion of total propagule levels. LU592 was shown to colonize the rhizosphere most effectively when 105 spores per pot were applied compared with inoculum concentrations of 103 and 107 spores per pot. LU592 extended its zone of activity beyond the rhizosphere to at least 1 cm away from the root surface. A positive...

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,...

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...

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...

Economics of organic versus chemical farming for three crops in Andhra Pradesh, India
Provedor de dados: 21
Autores: Sudheer, P. Sri Krishna.
To tackle the challenge of food grain production and food  security, chemical agriculture advocates call for the continuing or higher use of chemical fertilizers and synthetic pesticides. However, the continuous use and higher reliance on these inputs can lead to a reduction in  crop productivity, deterioration in the quality of natural resources and the eco-system. Organic farming offers a solution for sustainable agricultural growth and safeguarding the ecosystem. A conversion from chemical farming to organic farming can be a lengthy process, and during its course the farmer may incur a loss in income. The farmer will switch over only when he is convinced that in the long run, the benefits from organic farming are more than from chemical farming. A study...

Is organic agriculture so special that special social theories and methods are needed? The article investigates the question in two steps: First, the article address the question whether agriculture is special. Second, whether organic agriculture is special. It is concluded that from an economic point of view new research suggests that the organic sector can only be conceptualized and understood in the general social context. If the sector is analyzed as independent of general social context, it will lead to insufficient, and in worst case wrong, understandings and subsequently inadequate policy recommendations.

Effect of alternative strategies for the disinfection of tomato seed infected with bacterial canker (Clavibacter michiganensis subsp. michiganensis)
Provedor de dados: 21
Autores: Kasselaki, A. M.; Goumas, D.; Tamm, L.; Fuchs, J.; Cooper, J.; Leifert, C.
Currently there is a lack of effective seed treatments for bacterial pathogens, with Cu-based compounds (the only chemical treatments permitted under organic farming standards) only providing partial control.  The aim of this study was to quantify the effect of alternative treatments for the control of bacterial canker (Clavibacter michiganensis subsp. michiganensis), a major seed-borne bacterial disease in tomato.  Treatments assessed were acidified nitrite (a treatment previously shown to control the seed-borne fungal disease Didymella lycopersici), antagonistic strains of Bacillus spp. and compost extracts, which were not previously evaluated as treatments for seed-borne diseases. Efficacy of treatments was determined in a seed disinfection assay....

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...

Effect of artificial structuring on the use of laying hen runs in a free-range system
Provedor de dados: 21
Autores: Zeltner, Esther; Hirt, Helen.
1. This study examined whether a free range with roofed boxes with sand to structure the hen run had an effect on the numbers of hens going outside and on the distribution of the hens in the hen run.  2. On a poultry farm with 8 flocks of laying hens of roughly 500 birds per flock, each flock was observed with and without roofed boxes with sand.  3. There was no difference in the number of hens on free range with and without roofed boxes but there was an influence on the distribution.  4. In free range with structures there was a higher percentage of the hens outside in the furthest quarter where the structures were located.  5. We conclude that structures in the free range have an effect on the distribution of laying hens.

Effect of barley-legume intercrop on disease frequency in an organic farming system
Provedor de dados: 21
Autores: Kinane, Dr. J.; Lyngkjær, Dr. M.
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.

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...

The objective was to compare the performance and meat quality of two different pig breeds: The modern crossbred Landrace x Yorkshire (LY) and the traditional Danish Black-Spotted (BS) breed. The LY gilts and four of the BS gilts were inseminated with semen from Duroc (D) boars, the remaining BS gilts were served by BS boars. The experiment was performed on 26 gilts over two years.     RESULTS: The Black Spotted breed in general had smaller litter sizes and weaned on average in terms of kg piglet 35% less than the modern breed combination. Crossbred piglets of BS×D had growth rates from birth to weaning comparable with piglets of LY×D. Black Spotted first parity sows were significantly fatter and less meaty, and the meat was significantly redder and darker...

Provedor de dados: 21
Autores: Sehested, Jakob; Kristensen, Troels; Søegaard, Karen.
The proportions of organic feed and roughage in the feed ration for organic dairy cows have to reach 100 and 60%, respectively, in 2005. The aim of this study was to elucidate the long-term effects of reducing or omitting concentrate supplementation to high genetic merit dairy cows on a basal ad libitum diet of clover-grass (silage and grazing). Three concentrate levels, N, L and L+ (38, 0 and 19% of dry matter (DM) intake, respectively) were investigated in a herd of 60 cows during 3 years. The production in group N was 6723 kg energy corrected milk (ECM) per cow year, based on an intake of 6226 kg DM of which 38% was concentrates. In group L the omission of concentrates reduced intake to 4770 kg DM, and milk production to 5090 kg ECM per cow year. Milk...

Effect of conservation tillage and peat application on weed infestation on a clay soil
Provedor de dados: 21
Autores: Vanhala, Petri; Pietola, Liisa.
Amendment of soil with peat is an attempt to avoid crop yield variation in the transition to conservation tillage, as it improves seedbed conditions and crop growth in drought-sensitive clay soils. Weed infestations were compared in 1999-2000 between the original and peat-amended clay (Typic Cryaquept, very fine, illitic or mixed) under different autumn tillage systems in an oats-barley rotation. In a field experiment, sphagnum peat (H = 4) had been spread (0.02 m 3 m -2 ) on the soil surface in August 1995. Tillage treatments included mouldboard ploughing (to 20 cm) and stubble cultivations of different working depths (8 or 15 cm) and intensity (once or twice). Weed biomass and density were assessed by an area of 1 m 2 per field plot in August 1999-2000...

Provedor de dados: 21
Autores: CASTELLINI, Prof C; MUGNAI, Dr C; DAL BOSCO, Dr A.
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. Instead cooking loss, lightness values, shear values, Fe,...

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...

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.

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....

Effect of deep and shallow root systems on the dynamics of soil inorganic N during 3-year crop rotations
Provedor de dados: 21
Autores: Thorup-Kristensen, K.
Unused inorganic N (Ninorg) left in agricultural soils will typically leach to deeper soil layers. If it moves below the root zone it will be lost from the system, but the depth of the root zone depends on the crop species grown. In this experiment we studied the effect of three-year crop sequences, with different combinations of deep and shallow rooted crops, on soil Ninorg dynamics to 2.5 m soil depth and the possibility of crop utilization of N leached to deep soil layers.    We grew 10 different crop sequences for three years. The crops and catch crops grown were selected to allow different sequences of deep and shallow rooted crops. Very different rooting depths were obtained, from only 0.5 m (leek), to approximately 1.0 m (ryegrass and barley), 1.5 m...

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...

Effect of defoliation height on regrowth of timothy and meadow fescue in the generative and vegetative phases of growth
Provedor de dados: 21
Autores: Virkajärvi, Perttu.
Post-defoliation carbohydrate stores, leaf area and the number of active meristems are important factors affecting the subsequent regrowth of grasses. Defoliation height affects the magnitude of all these factors. Timothy (Phleum pratense L.) and meadow fescue (Festuca pratensis Huds.) are the two most common pasture species in Finland, but little is known about their response to defoliation height. In this study the effect of three defoliation heights, 3, 6 and 9 cm, on the regrowth rates of timothy and meadow fescue in both the generative (June–July) and vegetative (August) phases of growth were examined in two one-year experiment in year 2000 and 2001. In addition, the main postdefoliation parameters were measured and their contributions to regrowth...

Effect of Different Defoliation Systems of Ryegrass–Clover on Yield and Selected Quality Parameters of Organic Potatoes (Solanum tuberosum L.) for Industrial Processing at Harvest and After Storage
Provedor de dados: 21
Autores: Dresow, Jana; Krause, Tanja; Haase, Norbert U.; Loges, Ralf; Heß, Jürgen; Böhm, Herwart.
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...

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...

Effect of differential N and S competition 1 in inter- and sole cropping of Brassica species and lettuce on glucosinolate concentration
Provedor de dados: 21
Autores: Stavridou, Eleftheria; Kristensen, Hanne L.; Krumbein, Angelika; Schreiner, Monika.
Field and greenhouse pot experiments were conducted to evaluate the potential to use intercropping as an alternative method to increase glucosinolates in Brassicas by manipulating nitrogen (N) and sulphur (S) balance by intercropping with lettuce (Lactuca sativa L. var. capitata). In both experiments, four combinations of N and S fertilization were used. In the field experiment no effect of intercropping on the total glucosinolates was found as the growing lettuce was strongly inhibited by the presence of broccoli (Brassica oleracea L. var italic). The reduction in neoglucobrassicin in broccoli from intercropping was probably attributed to the lower N concentrations in broccoli florets. In contrast to this, in the pot experiment both total and individual...

Provedor de dados: 21
Autores: Neri, L.; Santarelli, V.; Di Mattia, C.; Sacchetti, G.; Faieta, M.; Mastrocola, D.; Pittia, P.
The effect ofdipping and vacuum impregnation (VI) pretreatments with lemon juice solution on the quality and stability of organic and conventional frozen apples was investigated. Fresh apples were characterized; organic apples showed, at equal starch and ripeness index, a lower sugar content, and higher acidity than conventional ones. The polyphenol content was slightly higher in organic apples than in conventional ones while polyphenoloxidase activity was similar. No differences in color and firmness were evidenced. Dipping affected organic and conventional apples’ color by determining an increase of lightness (!L∗ ! 4) and h° (!h° ! 6) parameters. VI reduced the lightness of apples (!L∗ ! −3) but the addition of lemon juice counterbalanced the lightness...

Autores: Andrasen, Annette; Sengupta, Mita Eva; Skovgaard, Kerstin; Jensen  , Bent Borg; Thamsborg, Stig MIlan; Kringel, Helene; Petersen, Heidi Huus; Mejer, Helena.
It has been shown that carbohydrates that are resistant to digestion in the small intestine but fermentable  in the caecum and colon (prebiotics) may be adverse to Oesophagostomum detatum establishment in pigs and have a severe negative effect on egg production. However, there is some evidence that O.dentatum may adapt to the presence of chicory in the feed over time, and  is Thus very relevant to examine the long-term effect on the parasite.

Effect of faecal soiling on skatole and androstenone occurence in organic entire male pigs
Provedor de dados: 21
Autores: Thomsen, Rikke; Edward, Sandra E.; Jensen, Bent Borg; Rousing, Tine; Sørensen, Jan Tind.
Production of entire male pigs could be a future strategy for organic pig production.  However, production of entire males leads to increased risk of carcasses with elevated boar taint levels. It is hypothesized that skatole levels in pig meat are affected by soiling with manure and that organic housing facilities can increase the risk of pigs being heavily soiled. Therefore the overall aim of this study was to investigate if increased pig and pen soiling increases skatole concentration in entire male pigs. In 5 herds, 1174 organic entire male pigs were reared in four batches across two seasons, summer and winter. Measurements of pig and pen soiling, as well as fat skatole and androstenone concentration and human sensory tests of fat odour, were performed....

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...

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...

Effect of four plant species on soil 15N-access and herbage yield in temporary agricultural grasslands
Provedor de dados: 21
Autores: Pirhofer-Walzl, Karin; Eriksen, Jørgen; Rasmussen , Jim; Høgh-Jensen, Henning; Søegaard, Karin; Rasmussen, Jesper.
Positive plant diversity-productivity relationships have been reported for experimental semi-natural grasslands (Cardinale et al. 2006; Hector et al. 1999; Tilman et al. 1996) as well as temporary agricultural grasslands (Frankow-Lindberg et al. 2009; Kirwan et al. 2007; Nyfeler et al. 2009; Picasso et al. 2008). Generally, these relationships are explained, on the one hand, by niche differentiation and facilitation (Hector et al. 2002; Tilman et al. 2002) and, on the other hand, by greater probability of including a highly productive plant species in high diversity plots (Huston 1997). Both explanations accept that diversity is significant because species differ in characteristics, such as root architecture, nutrient acquisition and water use efficiency,...

Autores: Kongsted, A.G.; Jakobsen, M.
Organic food production is developing rapidly in Europe and other parts of the world. An important principle in organic production is “to provide living conditions that allow animals to express the basic aspects of their innate behaviour” (IFOAM, 2002). This principle is accentuated in the European regulations on organic production as “the livestock shall have permanent access to open air areas, preferable pasture” (EC No 834/2007).

Autores: Wiking, L.; Theil, Peter K.; Nielsen, Jacob H.; Sørensen, Martin T.
The impact of fresh legume types or silage on the composition of milk fatty acids and transcription of enzymes involved in the synthesis of milk fat in cows was studied. Three groups of cows grazed white clover, red clover and lucerne, respectively. A fourth group of cows was fed maize/grass silage. The cows grazing high proportions of legumes produced significantly more C18:1 trans-11, C18:2 cis9-trans11, C18:2 trans10-cis12 and C18:3 fatty acids than cows fed silage. White clover and lucerne grazing resulted in significantly less output of C18:1 trans9 in milk than red clover grazing and maize/grass silages. The transcription of Stearoyl-CoA desaturase (SCD) in mammary tissue was significantly increased by grassing high proportions legume whereas fatty...

Effect of human-animal relationship and management on udder health in Swiss dairy herds
Provedor de dados: 21
Autores: Ivemeyer, Silvia; Knierim, Ute; Waiblinger, Susanne.
In a cross-sectional study, we investigated the effects of human-animal interactions and management factors on udder health in 46 Swiss dairy herds living in loose-housing systems on farms that participated in the Swiss dairy farm network “pro-Q.” The human-animal relationship was measured by observing milkers´ behavior, cows’ behavior during milking, and cows’ avoidance distance in the barn. Management factors were assessed by questionnaire-guided interviews and observations. Udder health was evaluated using indicators that were calculated from milk recording data over a period of 1 yr before assessment: (1) average somatic cell scores (SCS) per herd and (2) incidence of new infections per herd (NEWINF); and indicators that were calculated from quarter...

Provedor de dados: 21
Autores: Eekeren, Nick J.M.; Bos, Merijn M.; Wit, J. de; Keidel, H.; Bloem, J.
For the purpose of feeding value, drought resistance and nitrogen utilization, other grasses (e.g. Festuca arundinacea and Dactylis glomerata) than the currently widely used perennial rye grass (Lolium perenne) are introduced in dairy farming, either as a monoculture or in a mixture. To study the effect of these grasses on yield and soil chemical and biological quality, the three species were sown in a field experiment in monoculture and in two mixtures.Within two growing seasons, the grass species tested under high soil fertility conditions did not show significant effects on most of the tested soil biological parameters. Only for the mixture of L. perenne and D. glomerata a higher soil NO3− and mineral N content were most probably related to a higher...

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...

The feasibility of the rice-duck system of rice production, practiced in some East Asian countries, is studied in Bangladesh as a sub-project of the Poverty Elimination Through Rice Research Assistance (PETRRA). The Bangladesh Rice Research Institute (BRRI) implements the sub-project in collaboration with two NGOs, FIVDB and BDS, in the northeastern (greater Sylhet) and southern (Barisal) regions of the country. Each demonstration trial, conducted in the field of the farmers, is treated as a replication. In these trials, the rice-duck system is compared with the methods of growing rice solely, as traditionally practiced by the farmers in Bangladesh. Evaluation of the activities carried out under the PETRRA sub-project shows that the rice-duck system is not...

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...

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)...

Effect of legume–grass silages and a-tocopherol supplementation on fatty acid composition and a-tocopherol, b-carotene and retinol concentrations in organically produced bovine milk
Provedor de dados: 21
Autores: Höjer, Annika; Adler, Steffen; Martinsson, Kjell; Jensen, Søren K.; Steinshamn, Håvard; Thuen, Erling; Gustavsson, A.-M.
Two feeding experiments were performed to study the effects of silage botanical composition, regrowth interval and α-tocopherol supplementation on the fatty acid (FA) composition and α-tocopherol, β-carotene and retinol concentrations of milk. In experiment 1, 24 Swedish Red dairy cows were fed two- or three-cut red clover-grass silages (R2 and R3, respectively), or two-cut birdsfoot trefoil-grass silage (B2). In experiment 2, 16 Norwegian Red dairy cows were fed short-term ley silage with red clover (S3) or long-term ley silage with white clover (L3) in combination with supplementation of RRR-α-tocopheryl acetate (1,600 mg/day). The FA proportions in the milk and the recoveries of C18:2n-6 and C18:3n-3 were higher on the red clover diets R2 and S3 than on...

Autores: Aflatuni, Abbas; Uusitalo, Jouko; Ek, Sari; Hohtola, Anja.
Soil acidity commonly limits plant production in the fine sand soil of Northern Finland, which often has a low pH (5.5-6.5) and contains low levels of Ca and Mg. The effect of five liming (10% Mg and 19% Ca) levels, 0, 4, 8, 12, and 16 tons ha -1 , on the herb and essential oil yield and menthol and menthone content of two mint species (peppermint, Mentha x piperita, a variety of Black Mitcham and Sachalin mint, Mentha arvensis var. sacchalinensis) cultivated in fine sand soil in Northern Finland (6440’N and 2505’E) was studied during 1998-2000. Liming clearly increased the pH levels and the Ca and Mg content of the soil. The dry matter content, essential oil quantity, and the menthol or menthone content in mints were not affected by liming. In comparison...

Effect of low and ultra-low temperature applications during freezing and frozen storage on quality parameters for fish
Provedor de dados: 21
Autores: Tolstorebrov, Ignat; Eikevik, Trygve Magne; Bantle, Michael.
The article reviews recent investigations in the application of ultra-low temperatures for high-quality long-term storage of fish. Changes in fish quality were discussed with respect to thermal events, which occur at low and ultra-low temperatures. Excellent stability of proteins was found at temperatures below the end of freezing point, when the unfrozen water content is at its minimum. Lipid oxidation was inhibited by preventing oxygen penetration to fish tissues rather than decreasing storage temperature. Thus, a significant part of fish oils remains unfrozen until temperatures of −110.0°C. The recommended storage temperature for high-quality long-term storage of fish is −35.0°C. Further decreasing storage temperature is unnecessary for industrial needs.

Effect of management of topsoil structure
Provedor de dados: 21
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.

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...

The aim of this study was to assess whether different grazing management affect animal performance and meat fatty acid composition. Thirty-five lambs were divided into three groups: 12 lambs grazed from 9 am to 5 pm (8h group); 11 lambs grazed from 9 am to 1 pm (4hAM group) and 12 lambs grazed from 1 pm to 5 pm (4hPM group). The trial was conducted over 72 days. The 8h lambs had greater DMI (P &lt; 0.0005) and final body weight (P &lt; 0.05) than the 4hPM and 4hAM lambs while carcass weight was not different between the three groups. The meat of the 4hPM lambs contained greater (P &lt; 0.05) percentages of polyunsaturated fatty acids, C18:2 cis-9 trans-11 and lower saturated fatty acids and C18:0 than the meat of the 8h and 4hAM lambs.

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 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...

Autores: Musyoka, Martha W.; Adamty, Noah; Muriuki, Anne W.; Cadisch, Georg.
Increased per capita food production in the tropics is closely tied to soil organic matter and water management, timely nitrogen (N) supply and crop N use efficiency (NUE) which are influenced by farmingsystems. However, there is lack of data on the effect of organic farming systems on NUE and how thiscompares to conventional farming systems under tropical conditions. Therefore, the objectives of thisstudy were to determine the effect of conventional and organic farming systems at low and high management intensities on N uptake and N use efficiency of potato (Solanum tuberosum L.), maize (Zea mays L.),cabbage (Brassica oleracea var.

Effect of organic and conventional practices on the insects natural enemies communities in agricultural landscapes
Provedor de dados: 21
Autores: Puech, Camille; Baudry, J.; Aviron, Stéphanie.
Food security and biodiversity conservation are among the main challenges of modern agriculture. Organic Farming (OF) is considered as a promising type of production to meet these challenges due to the use of alternative practices on organic systems. In particular, biological control of pests by their natural enemies is considered as a possible way to reduce pesticide use in Conventional Farming (CF). The aim of this work is to describe the diversity of practices on winter wheat in organic and conventional farms, and to understand their effects on natural enemies, at field and landscape scales. Entomological surveys and agronomic surveys were carried out in forty fields (twenty under OF and twenty under CF) located in different landscape contexts. The...

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...

Effect of organic growing systems on sensory quality and chemical composition of tomatoes
Provedor de dados: 21
Autores: Thybo, Anette K.; Edelenbos, Merete; Christensen, Lars P.; Sørensen, Jørn Nygaard; Thorup-Kristensen, Kristian.
Tomato plants were grown in open beds, confined beds, or combined beds with compost based on clover grass hay, deep litter and peat. Due to only minor effects of growing systems on sensory quality and chemical composition of tomato fruits is was concluded that it is possible to produce tomato fruits in confined and combined soil bed systems without any loss in eating quality. Actually the results indicate, that a slight increase in quality of tomatoes from the confined and combined systems is obtained. The present result points to the fact that confined and combined growing systems may be new relevant commercial growing systems, in which the quality of tomatoes seems to be ensured, and in which nutrient loss and root diseases contamination can be reduced.

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)...

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...

Nitrate leaching from outdoor pig production is a long-standing environmental problem for surface and groundwater pollution. In this study, the effects of inclusion of poplar trees in paddocks for lactating sows on nitrogen (N) balances were studied for an organic pig farm in Denmark. Vegetation conditions, soil water and nitrate dynamics were measured in poplar and grass zones of paddocks belonging to main treatments: access to trees (AT), no access to trees (NAT) and a control without trees (NT), during the hydrological year April 2015 to April 2016. Soil water drainage for each zone, simulated by two simulation models (CoupModel and Daisy), was used to estimate nitrate leaching from the zones in each paddock. N balances (input minus output) for the...

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...

The aim of this work was to evaluate the effect of pulsed electric field (PEF) pre-treatment on mass  transfer phenomena, water distribution and some physico-chemical parameters of osmo-dehydrated  organic strawberries. For PEF treatments 100 near-rectangular shaped pulses, with fixed pulse width  of 100 ms and repetition time of 10 ms were used. Electric fields strength applied were 100, 200 and  400 V/cm  . Afterwards, samples were subjected to OD treatments carried out in two different hypertonic  solutions (40% w/w), one with sucrose and the other one with trehalose. The results shown that PEF  treatment positively affected the mass transfer during OD even at the lowest electric field strength  applied (100 V/cm), partially preserving the cell...

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...

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...

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...

Effect of Rhizome Fragmentation, Clover Competition, Shoot-Cutting Frequency, and Cutting Height on Quackgrass (Elymus repens)
Provedor de dados: 21
Autores: Ringselle, Bjørn; Melander, Bo.
Quackgrass is a problematic agricultural weed in the temperate zones of the world and is difficult to control without herbicides or intensive tillage. However, it may be possible to control quackgrass with less environmental impact by combining multiple low-intensity control methods. A pot experiment was conducted in July to October 2012 and repeated in June to September 2013 to investigate the effect of rhizome fragmentation, competition from white clover, shoot-cutting frequency, and cutting height on quackgrass. Rhizome fragmentation was expected to result in more, but weaker, quackgrass shoots that would be more vulnerable to shoot cutting and competition. However, by 20 d past planting, rhizome fragmentation did not change the total number of...

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...

Effect of short-term versus long-term grassland management and seasonal variation in organic and conventional dairy farming on the composition of bulk tank milk
Provedor de dados: 21
Autores: Adler, Steffen A.; Jensen, S.K.; Govasmark, Espen; Steinshamn, Håvard.
Bulk tank milk from 28 dairy farms was sampled every second month for 2 yr to assess the effects of grassland management, production system and season on milk fatty acid (FA) composition, concentrations of fat-soluble vitamins, Se, and milk sensory quality. Grassland management varied in terms of time since establishment. Short-term grassland management (SG) was defined as establishment or reseeding every fourth year or more often, and long-term grassland management (LG) was defined as less frequent establishment or reseeding. Fourteen organic (ORG) dairy farms with either short-term or long-term grassland management were paired with 14 conventional (CON) farms with respect to grassland management. Within ORG farms, SG farms differed from LG farms in...

Thanks to positive interactions between species, growing mixtures of cover crops allows improving the ecosystem services provided by cover crop cultivation. In this study, the influence of species diversity but also of species identity and mixture composition on cover crop biomass production and its stability in diverse growing conditions was studied. Several field experiments (varying soil type, preceding crop, soil tillage, sowing density, nitrogen fertilization and spatial replication) were set up in Switzerland during the period 2013−2016. In these experiments, the performance of cover crop species grown as sole crops was compared to that of multispecific mixtures. Part of these experiments followed a simplex design in which four cover crop species...

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.

This study examined the environmental impact of the three common organic pig husbandry systems, indoor (n = 24), partly outdoor (n = 30), and outdoor (n = 10), in eight European countries. Global warming (GWP), acidification (AP), and eutrophication potential (EP) was assessed per 1000 kg pig live weight on 64 farrow-to-finish pig production chains (cradle to farm gate). GWP, AP, and EP varied greatly, and the most important source was feed production, followed by housing. GWP did not differ between systems (p = 0.934), but AP in indoor systems and EP in outdoor systems were higher than in partly outdoor systems (p = 0.006 and p = 0.010, respectively). The higher AP in indoor systems can mainly be explained by NH3 arising from manure spreading, while...

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...

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...

Effect of topdressing on individual leaf photosynthesis at different position in direct-sown rice with non-woven fabric mulch system
Provedor de dados: 21
Autores: Hossain, Shaikh Tanveer; Sugimoto, Hideki; Yamashita, Jun.
Direct sowing with non-woven fabric mulch is the new organic rice cultivation system. We studied the effect of topdressing on individual leaf photosynthesis at different position and grain yield in rice plants cultivated by this system. Leaf photosynthetic rate at the different leaf position per plant (P N-LP) of the third and fourth to lower leaves was higher when the topdressing amount was increased. Without topdressing or in no-fertilizers plots, the P N-LP values of lower leaves were very low. The leaf photosynthetic rate per unit leaf area (P N-LA) decreased gradually as the leaf position became lower. Again, the P N-LA values of the top-dressed plots at the lower leaves were higher than that of plots without topdressing or without fertilizers. The...

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....

Provedor de dados: 21
Autores: Parveaud, Claude-Eric; Gomez, Christelle; Bussi, Claude; Capowiez, Yvan.
In orchards, cover crops are interesting alternative strategies to tillage or chemical herbicides for managing weeds in the tree row. However, little is known about the effect of cover crops on agronomic properties and soil biology in organic orchards. To fill this gap, the effects of two weed managements, a White clover cover crop (CC) versus classical tillage practice (T) on the tree row, were assessed in an irrigated organic Peach orchard. White clover was sown in 2004, 2006 and 2009 in the tree row and ploughed in 2006 and 2008. Root density, earthworm density, water infiltration rate, nitrogen content and water availability were measured in the soil, in the tree row. In 2009, peach root density observed in the superficial layers was higher in CC...

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...

Over three million tonnes (t) of tilapia, mostly Nile tilapia (Oreochromis niloticus, L.), are produced annually making it the second most abundantly produced freshwater fish (FAO, 2010). Tilapia are mouthbreeders that often produce stunted populations under pond conditions; one means of prevention is to produce all-male fish with the additional advantage that males usually grow faster than females. All-male populations can be achieved by supplementing feed with androgens such as 17-α-Methyltestosterone (MT) during days 10–25 post-hatch (Pandian and Sheela, 1995). However, MT is considered to be carcinogenic (Velazquez and Alter, 2004), and Hulak et al. (2008) also showed that effluents of systems in which carp were fed diets containing MT caused...

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...

A range of studies have compared the level of nutritionally relevant compounds in crops from organic and nonorganic farming systems, but there is very limited information on the effect of farming systems and their key components on the protein composition of plants. We addressed this gap by quantifying the effects of different farming systems and key components of such systems on the protein profiles of potato tubers. Tuber samples were produced in the Nafferton factorial systems study, a group of long-term, replicated factorial field experiments designed to identify and quantify the effect of fertility management methods, crop protection practices and rotational designs used in organic, low input and conventional production systems. Protein profiles were...

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...

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...

Autores: Wyss, Eric; Daniel, Claudia.
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: Bürgel, K.; Daniel, Claudia; Wyss, Eric.
Autumn applications of the repellent processed-kaolin particle film (Surround ® WP) might be an alternative to the insecticides commonly used in spring to control the rosy apple aphid, Dysaphis plantaginea (Pass.) (Hom., Aphididae). To assess the mode of action and the impact of kaolin on autumn forms of D. plantaginea, trials were conducted in field cages and in open-fields in autumn 2003. Choice and no-choice experiments in field cages showed that winged aphids landed in significantly lower numbers and gave birth to significantly fewer females on kaolin-treated branches compared with the untreated control. In a first open-field trial, single applications at 10 different dates and with two different concentrations of kaolin were conducted after harvest to...

Autores: Elsgaard, Lars; Elmholt, Susanne; Jørgensen, Martin Heide.
Band-steaming of arable soil at 80–90 °C kill off weed seeds prior to crop establishment which allows an extensive intra-row weed control. Here we evaluated the side-effects of in situ band-steaming on soil respiration, enzyme activities, and numbers of culturable bacteria and fungi in an organic field soil. The results showed that mechanical disturbance created by band-steaming could be neglected as a mediator of microbial changes. Also, soil pH and water content was unaffected by band-steaming. Effects of band-steaming on in situ soil respiration and basal respiration, respectively, were insignificant or slightly stimulatory (P &lt; 0.05). Fluorescein diacetate hydrolysis and arylsulfatase activity were significantly (P &lt; 0.001) inhibited by 25 and...

Autores: Pfiffner, Lukas; Mäder, Paul.
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...

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...

Autores: Sapkota, Tek Bahadur; Askegaard, Margrethe; Lægdsmand, Mette; Olesen, Jørgen Eivind.
Catch crop root growth and nitrogen (N) uptake from both shallower and deeper soil layers is important for N management in arable farming system particularly in climates where excess winter precipitation induces N leaching. We simulated the root growth and biomass yield of three common catch crops [chicory (Cichorium intybus L.), fodder radish (Raphanus sativus L.) and perennial   ryegrass (Lolium perenne L.)] and their effect on soil mineral N in different soil layers by using the FASSET model. The simulated results of catch crops root growth and mineral N in the soil profile were validated against two years (i.e. 2006 and 2007) of observations taken in Foulum and Flakkebjerg, Denmark. Fodder radish had the deepest root system and depleted N from deeper...

Effects of Cattle Slurry on the Growth Potential and Clover Proportion of Organically Managed Grass–Clover Leys
Provedor de dados: 21
Autores: Steinshamn, Håvard.
The growth potential of grass-clover leys as influenced by cattle slurry application and clover content was studied in field experiments during three growing seasons at four locations. A grassland growth model was used to quantify growth potential and to separate the influence of weather variables from factors related to the plant stand. Application of cattle slurry increased the initial relative growth rate (R-s), on average from 0.21 to 0.23 g g(-1) day(-1) of the spring growth. In regrowth the effect of cattle slurry was less pronounced. The effect of cattle slurry declined with increasing R-s of the unfertilized treatment and rose with increasing rate of ammonium N applied by the slurry. The positive response to cattle slurry application on R-s was...

The aim of this work was to evaluate the efficacy of an innovative edible coating, based on chitosan from mushrooms enriched with procyanidins extracted from grape seeds, on fresh blueberry quality maintenance, (weight loss, pH, dry matter, colour, firmness and antioxidant activity) and microbial growth, during 14 days of storage at 4 °C.    For weight loss, pH and dry matter no relevant differences were detected among the control and the differently coated samples at each considered storage time. Chitosan and chitosan + procyanidins coatings promoted a slight decrease of luminosity and an increase of blue hue colour of blueberry samples during the whole storage period. The use of coating promoted an increase in the antiradical activity that was the...

A 2 × 2 factorial continuous experiment was conducted with 28 Norwegian Red dairy cows in early lactation to compare milk content of phytoestrogens when feeding ad libitum white clover (WCS) or red clover (RCS) grass silages prepared from the second and third cut without and with 10 kg/d supplementation of a standard concentrate. The cows were offered either RCS or WCS for 88 d (period 1) and thereafter a mixed red clover-white clover-grass silage for 48 d (period 2). Total dry matter intake and milk yield were not affected by forage type but increased with concentrate supplementation. Intake of isoflavones was several times greater in RCS than in WCS, whereas intake of lignans was  greater in WCS. Concentrate supplementation reduced the intake of most...

To evaluate the influence of compost on soil fertility and plant growth, several medium term and long term field experiments with composts were conducted in different crops.  In two maize experiments, one in a sandy and one in a loamy soil, the influence of different composts and digestates on soil parameters and plant growth were investigated. All products increased pH of the soil and improved the biological soil activity (e.g., enzymatic activities). Immature compost immobilized nitrogen and reduced plant growth. Organic nitrogen fertilizer added during cultivation, could compensate the growth depression.  A full factorial experiment in a 2-years-old organic apple orchard was conducted from 2001-2007.

The use of tanniferous plants or tannins represents one alternative approach to the  control of gastrointestinal parasites in ruminants but most data have been obtained in sheep. The  current study was therefore performed in goats with two objectives: firstly, to investigate the effects  of condensed tannins (CT) on adult populations of Trichostrongylus colubriformis and Teladorsagia  circumcincta; secondly, to examine their effects on the establishment of infective larvae of these  two species. In experiment 1, two groups of kids were infected with 6 000 L3 of T. colubriformis  and 6 000 L3 of T. circumcincta. After 7 weeks, quebracho extracts were administered per os for  8 days to one group. A comparable group which did not receive tannins was included...

Autores: Li, Xiaoxi; Petersen, Søren O.; Sørensen, Peter; Olesen, Jørgen E.
Abstract Legume-based catch crops (LBCCs) may act as an important source of nitrogen (N) in organic crop rotations because of biological N fixation. However, the potential risk of high nitrous oxide (N2O) emissions needs to be taken into account when including LBCCs in crop rotations. Here, we report the results from a one-year field experiment, which investigated N availability and N2O emissions as affected by three LBCCs, i.e., red clover (CL), red clover–ryegrass mixture (GC) and winter vetch (WV), two non-LBCCs, i.e., perennial ryegrass (GR) and fodder radish (FR), and a control (CO) without catch crops. The effect of two catch crop management strategies was also tested: autumn harvest of the catch crop versus incorporation of whole-crop residues by...

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...

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...

Autores: Melander, Senior scientist Bo; Rasmussen, Scientist Gitte.
Manual weeding of intrarow weeds in seeded leek and bulb onion grown organically can be very labour-intensive. Four field experiments, two in direct-sown leek (Allium porrum L.) and two in direct-sown bulb onion (Allium cepa L.), were made in this investigation to study the effects of physical and cultural methods on intrarow weed numbers, time consumption for hand-weeding and marketable yield parameters. The physical methods considered were: pre-emergence flaming and harrowing, and post-emergence hoeing close to the row (only leek) and vertical brush weeding. The cultural methods were: seed priming, slurry placement, and cultivar choice (only leek). Flaming plus brush weeding gave generally the highest intrarow weed control at 92% and 87%, respectively,...

Autores: Vinther, F.P.
Nitrogen (N) accumulating in stubble, stolons and roots is an important component in N balances in perennial ryegrass-white clover swards, and the effects of cutting frequency on the biomass of above- and below-harvest height were studied during two consecutive years. Total dry matter (DM) and total N production, and N2 fixation, were measured at two cutting frequencies imposed in the summers of two years either by cutting infrequently at monthly intervals to simulate mowing or by frequent cutting at weekly intervals to simulate grazing. Total DM production harvested was in the range 3000 - 7000 kg DM ha-1 with lower DM production associated with the frequent cutting treatment, and it was significantly affected by the different weather conditions in the...

Effects of digestate from anaerobic digested cattle slurry and plant materials on soil microbiota and fertility
Provedor de dados: 21
Autores: Johansen, Anders; Carter, Mette S.; Jensen, Erik Steen; Hauggaard-Nielsen, Henrik; Ambus, Per.
Anaerobic digestion of animal manure and crop residues may be employed to produce biogas as a climate-neutral source of energy to provide fertilizers which allow recycling of plant nutrients on the farm. However, compared to fertilizing with the pristine input materials (e.g. raw animal slurry or plant residues), the effect on soil microbiota and soil fertility may be impacted due to the increased content of mineral nitrogen (N) and decreased amount of organic carbon (C); an issue of concern in especially organic farming systems.  An incubation study was performed where 1) water, 2) raw cattle slurry, 3) anaerobically digested cattle slurry + maize, 4) anaerobically digested cattle slurry + grass-clover, or 5) fresh grass-clover was applied to soil at...

Autores: Johansen, Anders; Carter, Mette S.; Jensen, Erik Steen; Hauggaard-Nielsen, Henrik; Ambus, Per.
Soil from the Højbakkegård experimental (BioConcens) field  was amended with nothing (control), each of two anaerobic digested (AD) materials (mixture of AD cattle manure and maize, mixture of AD cattle manure and cut off grass-clover material), raw cattle manure, and grass-clover in five individual treat-ments. The materials were incorporated homogeneously into the soil and sampled destructively at 0, 1, 3 and 9 days after incorporation. Besides, experiments were performed to follow the turnover of these materials, measured as accumulated respiration over a longer period. Measures included available organic soil carbon (cold- and hot-water extractable), soil mineral nitrogen concentration, soil pH, accumulated respiration over a two-week period, emission...

Effects of duration of Organic farming practice on vegetation in Danish field boundaries
Provedor de dados: 21
Autores: Petersen, S.; Axelsen, J.A.; Tybirk, K.; Aude, E.; Vestergaard, P.
Enrichment of biological diversity is assumed to reflect good ecosystem integrity. The aim of the study presented here was primarily to observe, whether organic dairy farming increases the biological diversity of field boundary vegetation when compared to conventional dairy farming. Secondly, the aim was to consider if increasing duration of the organic farming period also increases diversity. Thirdly, ecological interpretations of the data were given by comparing organic and conventional field boundaries in terms of general vegetation community patterns.     The results documented that diversity of plant species was significantly higher within the organic field boundaries. Analysis of community patterns revealed that Ruderal species and species with...

Effects of experimentally planting non-crop flowers into cabbage fields on the abundance and diversity of predators
Provedor de dados: 21
Autores: Ditner, Nadine; Balmer, Oliver; Beck, Jan; Blick, Theo; Nagel, Peter; Luka, Henryk.
Flowery field margins and intersowing of crops with flowers are used as management practices to promote arthropod biodiversity as well as biocontrol agents.  Positive effects of enhancement (in abundance and species richness) of hymenopteran parasitoids on control of Lepidoptera pests have previously been demonstrated. However, effects on predatory arthropods, which may also serve as pest control agents, remain unclear. In an experimental study in cabbage fields we tested how sown flower strips on field margins and intersowing with cornflower affected the species richness, abundance and community composition of ground beetles and spiders. Furthermore, we investigated whether effects of flower margins are dependent on the distance from the field margins. We...

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...

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...

Effects of feeding dairy cows different legume-grass silages on milk phytoestrogen concentration
Provedor de dados: 21
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...

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)...

Autores: D., BAHUAUD; C., MARTINEZ-ORTIZ DE MONTELLANO; S., CHAUVEAU; F, PREVOT; F., TORRES-ACOSTA; I., FOURASTE; H., HOSTE.
The anthelmintic properties of tanniferous plants and of their secondary metabolites represent one possible alternative to  chemotherapy that is currently being explored as a means of achieving sustainable control of gastrointestinal nematodes in  ruminants. Previous in vivo and in vitro results suggest that tanniferous plants can have direct anti-parasitic effect against  different stages of nematodes. However, the mode of action of the bioactive plant compounds remains obscure. The  objectives of the current study were (1) to examine the hypothesis that extracts of tanniferous plants might interfere with  the exsheathment of third-stage infective larvae (L3); (2) to assess the role of tannins in the process by examining the  consequence of adding an...

Autores: Etterlin, Pernille Engelsen; Ytrehus, Bjørnar; Lundeheim, Nils; Heldmer, Eva; Österberg, Julia; Ekman, Stina.
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...

Gardens have effects on the local ecology as well as on the wellbeing of the gardener, but few studies have attempted to study gardens using both ecological and social outcome variables. The aim of this exploratory study is to address this research gap by identifying the characteristics of gardens and the management practices of gardeners that enhance the outcomes of gardening, which we separate into three dimensions: human wellbeing, biodiversity, and soil quality. Data were collected from 18 gardens in Zurich, Switzerland and a typology of gardeners was dentified,which included ‘conservationist’, ‘functional’, ‘minimumeffort’,  ‘child-friendly’, and ‘aesthetic’ gardeners.

Effects of grazing strategy to limiting nitrate leaching in grazed grass-clover pastures on coarse sandy soil
Provedor de dados: 21
Autores: Hansen, E.M.; Eriksen, J.; Søegaard, K.; Kristensen, K.
Urinations of ruminants on grazed pastures increase the risk of nitrate leaching. The study investigated the effect of reducing the length of the grazing season on nitrate leaching from a coarse sandy, irrigated soil during 2006-2007. In both years precipitation was above the long-term mean. The experiment was initiated in a 4-year-old grass-clover in south Denmark. Three treatments were included: grazing only (G), spring cut followed by grazing (CG) and both spring and autumn cuts with summer grazing (CGC). Nitrate leaching was calculated by extracting water isolates from 80 cm depth using ceramic suction cups. Because of considerable variation in measured nitrate concentrations, the 32 installed suction cups per treatment were insufficient to reveal...

Effects of grazing system on production and parasitism of dairy breed heifers and steers grazing wet marginal grasslands
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.

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...

Effects of hot‐water and steam blanching of sliced potato on polyphenol oxidase activity
Provedor de dados: 21
Autores: Moscetti, Roberto; Raponi, Flavio; Monarca, Danilo; Ferri, Serena; Bedini, Giacomo; Massantini, Riccardo.
The worldwide potato production is considered the fourth-most important food sector due to the increasing use of potatoes as raw materials for high-convenience food. Colour is a crucial quality attribute in fresh-cut potatoes, and enzymatic browning, due to polyphenols oxidase (PPO), is related to unacceptability by consumer. Among additives used to minimize discoloration, sulphites are very common, but affected by health-related hazards and marketing issues. Viable alternatives are thermal treatments, used to inactivate enzymes and improve product shelf-life. In this study, the efficacy of hot-water and steam blanching from 80 to 90°C, used to inactivate PPO in 1-cm potato slices, was evaluated in terms of inactivation kinetic, substrate specificity and...

Effects of inter-row hoeing and fertilizer placement on weed growth and yield of winter wheat
Provedor de dados: 21
Autores: Melander, Bo; Cirujeda, Alicia; Jørgensen, Martin Heide.
Inter-row hoeing is known to control tap-rooted and erect weed species more effectively in winter wheat than weed harrowing. However, little is known about its effectiveness for use in the spring in winter wheat grown at wide row spacing (240 mm) under the influence of different placement of fertiliser. Two field experiments, one in 1999 and one in 2000, were conducted to study the influence of fertiliser placement, timing of inter-row hoeing, and driving speed on the weeding effect on different weed species and crop growth. Placement of fertiliser below the soil surface improved crop growth and grain yield in both years compared with placement on the surface, but weeds surviving hoeing were not more suppressed by the improved crop growth. Timing was not...

Effects of inter-varietal diversity, biotic stresses and environmental productivity on grain yield of spring barley variety mixtures
Provedor de dados: 21
Autores: Kiær, Lars P.; Skovgaard, Ib M.; Østergård, Hanne.
Varietal seed mixtures tend to increase and stabilize crop yields, yet their application is sparse. Large-scale cultivation of variety mixtures may require a better understanding of how inter-varietal interactions and their interaction with the environment may influence the grain yield of variety mixtures relative to their component varieties. For this purpose, six variety mixtures of spring barley and 14 component varieties were grown in each of 17 trial environments. A total of 28 observed and a priori plant characteristics, including grain yield, disease severity and weed competitiveness, were derived for each component variety in each trial. The relationship between inter-varietal diversity of each characteristic and the mixing effect on grain yield...

Effects of Land Management Strategies on the Dispersal  Pattern of a Beneficial Arthropod
Provedor de dados: 21
Autores: Marchi, Chiara; Andersen, Liselotte Wesley; Loeschcke, V.
Several arthropods are known to be highly beneficial to  agricultural production. Consequently it is of great relevance to study the importance of land management and land composition for the conservation of beneficial aphid-predator arthropod species in agricultural areas. Therefore our study focusing on the beneficial arthropod Bembidion lampros had two main purposes: I) identifying the physical barriers to the species’ dispersal in the agricultural landscape, and II) assessing the effect of different land management strategies (i.e. use of pesticides and intensiveness) on the dispersal patterns. The study was conducted using genetic analysis (microsatellite markers) applied to samples from two agricultural areas (in Denmark) with different agricultural...

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.

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...

A six-year study was carried out in an organically managed orange orchard located in Sicily (Southern Italy) to assess the effect of compost and organic fertilizers utilisation on soil quality. Adopting a randomized-block experimental design with three replicates, four treatments were carried out. In treatments 1 and 2, two different composts (C1 from distillery by products and C2 from livestock wastes) were applied. The plots of treatment 3 were fertilized using dried poultry manure. The control  treatment was fertilized with mineral/synthetic fertilizers. In order to verify the hypothesis that composts and organic fertilizers improve soil fertility, soil quality was evaluated by selecting dynamic soil parameters, as indicators linked to C and N cycles....

Effects of low-input farming systems on carabids and epigeal spiders a paired farm approach
Provedor de dados: 21
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...

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...

Autores: Sundrum, Albert; Bütfering, L.; Henning, M.; Hoppenbrock, K.-H.
An experiment was conducted to evaluate the effects of a restriction to home-grown feedstuffs and abstinence from supplementation with synthetic amino acids (AA), as ideal objectives in organic pig production according to the IFOAM standards, on growth performance and carcass characteristics. One hundred individually housed pigs were allocated to four dietary treatments and fed from growing through finishing to compare three organic barley/wheat-based diets with an isocaloric conventional diet supplemented with synthetic AA. Protein sources in the organic treatments were either faba beans, supplemented with potato protein to the same AA level as the control diet (FA+PO), peas and lupines (PE+LU) or faba beans and lupines (FA+LU), both without further...

Autores: Søltoft, Malene; Bysted, A.; Madsen, K.H.; Mark, Alicja Budek; Bügel, Susanne; Nielsen, J.; Knuthsen, Pia.
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...

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...

Effects of organic farming on flies in Danish field boundaries
Provedor de dados: 21
Autores: Petersen, Sune.
The primary objective of this study was to see if organic farming increases the diversity and abundance of fly families in field boundaries when compared to similar conventional biotopes. Secondly, it was investigated whether an increasing organic farming period would increase diversity and abundance of flies. Furthermore, the results from the sampling programme were interpreted ecologically in terms of general community patterns by subjecting data to multivariate analysis.    The study revealed that biodiversity of flies was significantly higher within the organic field boundaries, but no difference was observed in terms of the organic farming period. Overall abundance of flies was similar in the groups and therefore affected by neither agricultural...

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 organic plant oils and role of oxidation on nutrient utilization in juvenile rainbow trout (Oncorhynchus mykiss)
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...

Effects of paddock management on vegetation, nutrient accumulation, and intrnal parasites in laying hens
Provedor de dados: 21
Autores: Maurer, Veronika; Hertzberg, Hubertus; Heckendorn, Felix; Hördegen, Philipp; Koller, Martin.
Management of paddocks for free-range layers requires an effort from farmers to minimize the adverse effects of these systems on animal health (e.g., parasites)and environment (e.g., nutrient accumulation and leaching). In this study, we report results from 2 on-farm experiments conducted to investigate (1) the effects of rotational versus continuous use of the paddocks and(2) the effects of wood chips in the area close to the pop holes (openings to the paddock) with regard to turf quality, nutrient load in the soil, and parasite infections. Rotational use of the hen paddocks led to a lower proportion of bare soil close to the house, but not in more distant regions. Covering the area in front of the house with wood chips did not reduce bare areas. Nitrogen...

The effects of plant growth promoting bacteria (PGPB) on the fruit yield, growth and nutrient element  content of strawberry cv. Fern were investigated under organic growing conditions between 2006 and  2008. The experimental plot was a completely randomized design with 3 replicates. Three PGPB strains  (Pseudomonas BA-8, Bacillus OSU-142 and Bacillus M-3) were used alone or in combination as biofertilizer  agent in the experiment. Data through 3 years showed that the use of PGPB significantly  increased fruit yield, plant growth and leaf P and Zn contents. Root inoculation of M3 and floral and foliar  spraying of OSU-142 and BA-8 bacteria stimulated plant growth resulting in significant yield increases.

Autores: Vinther, F.P.; Hansen, E.M.; Olesen, J.E.
The impacts of crop rotation and input of organic matter in the form of green manure crops, straw residues and incorporation of catch crops on crop yield, nitrogen uptake, microbial biomass and activity was studied in unfertilised crop rotations differing in input of plant residues, i.e. high-input rotations with a grass-clover crop and catch crops included and low-input cereal rotations without catch crops. The parameters studied included substrate induced respiration (SIR), hydrolysis of fluorescein diacetate (FDA), arylsulfatase activity (ASA), N mineralisation, N2O emission, and soil respiration. These parameters were measured in bare soil plots, to estimate the effects of previous years crops and input of plant residues. In neighbouring plots crop...

Autores: Riedel, Judith; Kägi, Nora; Armengot, Laura; Schneider, Monika.
Overaged full-sun cacao plantations and the need for sustainable production systems call for combining rehabilitation of plantations with the establishment of agroforestry. We tested the effect of drastic rehabilitation pruning of old cacao tree stock and the introduction of both high- and low-diversity agroforestry on survival, growth and yield of T. cacao in a commercial plantation in peninsular Malaysia over a period of 5 years. We further determined the incidence of pests and diseases of cacao pods and assessed the performance of the whole system for smallholder farmers, including yields of by-crops. Rehabilitation pruning negatively affected cacao tree development and short-term yield. No more effects of pruning on cacao yield were observed starting...

Docks (Rumex spp.) are a considerable problem in grassland production worldwide. We investigated how different cultural management techniques affected dock populations during grassland renewal: (I) renewal time, (II) companion crop, (III) false seedbed, (IV) taproot cutting (V), plough skimmer and (VI) ploughing depth. Three factorial split-split plot experiments were carried out in Norway in 2007–2008 (three locations), 2008–2009 (one location) and 2009 (one location). After grassland renewal, more dock plants emerged from seeds than from roots. Summer renewal resulted in more dock seed and root plants than spring renewal. Adding a spring barley companion crop to the grassland crop often reduced dock density and biomass. A false seedbed resulted in 71%...

Effects of ridging on crop performance and symbiotic N2 fixation of fababean (Vicia faba L.)
Provedor de dados: 21
Autores: Vinther, F.P.; Dahlmann-Hansen, L.
The success of organic cropping systems depends on symbiotic N2 fixation by leguminous crops, and it is important to explore new management systems to improve the nitrogen input through N2 fixation. During two growing seasons the possible advantage of growing fababean in ridges in comparison to the traditional method on the flat was studied. Differences in soil physical parameters resulted in a significantly greater microbial activity and a deeper root system at the flowering stage when grown in ridges than on the flat. Consequently, the amount of fixed N at flowering was significantly greater in ridges than in flat soil. However, during the period from flowering until harvest, when the major part of the N uptake and N2 fixation took place the differences...

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...

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...

Degraded areas in nineteen organically farmed European and Turkish vineyards resulted in producing significantly lower amounts of grapes and excessive concentrations of sugar. Plants suffered from decreased water nutrition, due to shallower rooting depth, compaction, and reduced available water capacity, lower chemical fertility, as total nitrogen and cation exchange capacity, and higher concentration of...

Provedor de dados: 21
Autores: Serenius, Marjo; Huusela-Veistola, Erja; Avikainen, Hanna; Pahkala, Katri; Laine, Antti.
Disease infection in relation to sowing time of winter rye (Secale cereale) was studied in southern Finland in order to compare overwintering capacity of modern rye varieties and to give recommendations for rye cultivation. This was done by using three sowing times and four rye varieties in field trials conducted at three locations in 1999–2001. The early sown rye (beginning of August) was severely affected by diseases caused by Puccinia recondita and Microdochium nivale, whereas postponing sowing for two weeks after the recommended sowing time resulted in considerably less infection. The infection levels of diseases differed among rye varieties. Finnish rye varieties Anna and Bor 7068 were more resistant to snow mould and more winter hardy than the Polish...

Effects of straw mulch on yield, weed development, nitrate dynamics and soil erosion in organically grown potatoes
Provedor de dados: 21
Autores: Döring, Thomas F.; Brandt, M; Heß, J; Finckh , M; Saucke, H.
The application of straw mulch to organic seed potatoes (Solanum tuberosum L.) has been shown to reduce virus incidence. In order to determine the associated agronomic effects of straw mulch, applied at 2.5–5 t ha�1, on soil nitrate dynamics, weed development, tuber yield and soil erosion, 12 field experiments were evaluated. Experiments were conducted on organic farms over 3 years at two locations in a temperate climate (635–709 mm precipitation/year; 8.1 8C mean air temperature) on loamy silt soils. Tuber yield and tuber size distribution were not influenced significantly by mulching. However, the risk of undesirable post harvest N-leaching was significantly reduced due to the immobilization of nitrate–N after harvest at 6.8–7.0 kg N t-1 straw in two...

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...

Effects of supplementing mid-lactation dairy cows with seaweed and vitamin E on plasma and milk α-tocopherol and antibody response to immunization
Provedor de dados: 21
Autores: Kidane, Alemayehu; Nesheim, Ingvild Luteberget; Larsen, Hans Jørgen S.; Thuen, Erling; Jensen, Søren K.; Steinshamn, Håvard.
The objective of the current experiment was to compare the effects of supplementing mid-lactation dairy cows with  all-rac-α-tocopheryl acetate (SyntvE), RRR-α-tocopheryl acetate (NatvE) or seaweed meal (Seaweed) in the presence  of a Control group (no supplemental vitamin E or seaweed) on the concentration of α-tocopherol in plasma and  milk, and antibody response following immunization. The hypothesis was that supplementation of dairy cows  with vitamin E, regardless of its form, would increase plasma and milk α-tocopherol compared to the control  diet and this incremental response would be bigger with NatvE than SyntvE. Furthermore, it was hypothesized  that vitamin E, regardless of its form, will provide an improved adaptive immune response to...

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,...

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:...

Effects of turning to 100% organic feed on metabolic status of Swedish organic dairy cows
Provedor de dados: 21
Autores: Blanco-Penedo, Isabel; Fall, Nils; Emanuelson, Ulf.
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,...

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....

Information is needed about root growth and N uptake of crops under different soil conditions to increase nitrogen use efficiency in horticultural production. The purpose of this study was to investigate if differences in vertical distribution of soil nitrogen (Ninorg) affected root growth and N uptake of a variety of horticultural crops. Two field experiments were performed each over 2 years with shallow or deep placement of soil Ninorg obtained by management of cover crops. Vegetable crops of leek, potato, Chinese cabbage, beetroot, summer squash and white cabbage reached root depths of 0.5, 0.7, 1.3, 1.9, 1.9 and more than 2.4 m, respectively, at harvest, and showed rates of root depth penetration from 0.2 to 1.5 mm day)1 C)1.

Autores: Manninen, Merja; Saarijärvi, Kirsi; Huhta, Harri; Jauhiainen, Lauri; Aspila, Pentti.
The present study evaluated the effects of feeding strategies with alternative feeds on the performance of mature suckler cows and their progeny during indoor feeding and subsequent grazing. In both experiments, a 2 × 2 factorially arranged design consisted of two feeding strategies (Step-up, S; Flat-rate, F) and two diets (Control, C; Alternative, A). The aim of Strategy F was to offer the cows the same amount of energy as offered on Strategy S, but at a constant daily level. In Experiment 1, cows on Diet C were offered grass silage and straw and on Diet A grass silage and a fl our-mill industry by-product. On Strategy S, feeding was stepped with barley (0, 1.5 and 3.5 kg d-1). On Strategy F, barley was offered 1.43 kg per head daily. In Experiment 2,...

Autores: Thuerig, Barbara; Ramseyer, Justine; Hamburger, Matthias; Ludwig, Mathias; Oberhänsli, Thomas; Potterat, Olivier; Schärer, Hans-Jakob; Tamm, Lucius.
In organic agriculture, the control of several diseases is largely depending on copper fungicides. Yet, copper can accumulate in the soil if the annual input exceeds annual uptake by plants, which can have a negative impact on soil fertility. Its use should thus be avoided or reduced.

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.

Efficient use of grassland nitrogen
Provedor de dados: 21
Autores: Eriksen, J.
In nitrate sensitive areas with agricultural production the recommended upper limit of nitrate in percolation water is 50 mg per litre. Organic farming has a lower nitrate leaching potential compared to conventional farming, but may occasionally exceed this limit, especially in the case of dairy crop rotations. In such rotations a considerable build-up of N takes place in grazed grassland. Therefore, organic dairy farming may only present an opportunity to reduce nitrate leaching if this grassland N is efficiently utilised. Losses may occur during grazing, and ploughing of grassland is followed by a large increase in the mineralization of N that often exceeds the need of the subsequent arable crop.    An experimental site at Research Centre Foulum has...

EFRC Cereal Variety and Mixture Trials 2001 – Preliminary Results
Provedor de dados: 21
Autores: Welsh, James.
Of 7 winter wheats grown at 3 sites in southern England in 2001, the highest yielding was the soft wheat Claire; the breadmaking varieties Hereward, Shamrock and Spark did well. Of the feed wheats, Aardvark outyielded Deben. Of various variety mixtures tried, Aardvark/Claire/Deben was highest yielding. When seed was saved from the 2000 harvest of Hereward/Malacca/Shamrock and grown in 2001, it outyielded the first generation mixture, suggesting that some adaptation had occurred, relative composition changing in response to the local conditions.   Winter oats and triticale were trialled at one site in Berkshire. The triticales Ego and Fidelio performed well, as did the winter oat Kingfisher.

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...

Heute arbeiten über 6000 Landwirtschaftsbetriebe in der Schweiz nach den Richtlinien der Bio Suisse. Das sind etwa elf Prozent aller Betriebe.Am stärksten ist der Bio-Landbau in der Bergzone verankert; Rekordhalter ist der Kanton Graubünden mit einem Bio-Bauern-Anteil von 50,3 Prozent. Erstmals in der 25-jährigen Geschichte der Bio Suisse war die Zahl der Bio-Betriebe im Jahr 2005 leicht rückläufig, während die ökologisch bewirtschaftete Fläche zunahm. Der Strukturwandel macht also auch vor dem Bio-Landbau nicht halt (Bio Suisse, 2006).

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,...

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...

Zusammenfassung  Die Entwicklung des ökologischen Landbaus in Europa ist im Wesentlichen durch zwei Faktoren geprägt: Durch die Verbrauchernachfrage nach Öko-Produkten und durch die staatliche Förderung über Flächenprämien und Richtlinien-definition. Es ist daher die politische Herausforderung, die richtige Balance zu finden zwischen staatlicher Unterstützung und den Mechanismen des Marktes zum Erzielen von Premiumpreisen. Ein Aktionsplan ist ein Instrument das geeignet ist, unterschiedliche und miteinander in  Konflikt stehende Politikmassnahmen zu integrieren. Der 2004 vorgestellte EU Aktionsplan für die ökologische Landwirtschaft und ökologisch erzeugte Lebensmittel berücksichtigt relevante Aktionspunkte hinsichtlich Richtlinien-gestaltung, Forschung...

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...

Eine kritische Analyse von Ruschs Theorien zur Bodenfruchtbarkeit als Grundlage für die Bodenbewirtschaftung im Ökologischen Landbau
Provedor de dados: 21
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...

Einfluss verschiedener Zwischenfrüchte als Vorfrüchte für die Ertrags- und Qualitätsleistung von Silomais und Kartoffeln
Provedor de dados: 21
Autores: Schliesser, Ingeborg; Schuster, Martina; Kolbe, Hartmut.
Mehrjährige Gefäß- und Feldversuche des Landesamtes für Umwelt, Landwirtschaft und Geologie in Sachsen zeigen, dass Zwischenfrüchte zu höheren Erträgen bei Silomais oder Kartoffeln führen können. Zudem konnte bei bestimmten Zwischenfrüchten eine deutliche Verringerung des Nitratgehalts im Boden nachgewiesen werden.  Insbesondere der Anbau von Weißem Senf, Sommerraps, Phacelia und Welschem Weidelgras verringerte den Nitratgehalt um bis zu 75 Prozent des Bodenausgangsgehaltes. Ähnliche Wirkung zeigten das Landsberger Gemenge und ein Gemenge aus Phacelia, Buchweizen und Platterbse. Damit können Zwischenfrüchte gut zur Verringerung des Nitrateintrags ins Grundwasser beitragen.    Bei reinen Leguminosen ist die Nitrataufnahme aus dem Boden aufgrund ihrer...

Autores: Luka, Henryk; Lutz, Michael; Blick, Theo; Pfiffner, Lukas.
Der Einfluss von eingesäten Wildblumenstreifen (Buntbrachen) auf die Laufkäfer- und Spinnenfauna der ehemaligen Flachmoorlandschaft und heute intensiv bewirtschafteten Kulturlandschaft "Grosses Moos"  (Schweizer Mittelland: Berner  Seeland) wurde untersucht. Drei mit einheimischen Wild- und Kulturpflanzen eingesäte Wildblumenstreifen verschiedenen  Alters sowie die angrenzenden  Getreidekulturen  in 15 m (Randbereich) und in 70 bis 100 m (Zentrumsbereich) Entfernung vom Wildblumenstreifen wurden mittels Trichterbodenfallen während 10 Fangwochen von Mai bis Juli 1999 beprobt. Von den 123 in 44.161 Individuen nachgewiesenen Laufkäfer- und Spinnenarten wurden insgesamt 110 in Wildblumenstreifen, 85 in den Randbereichen und 82 Arten in den Zentrumsbereichen...

Einfluss von Erwerbsart, Betriebsgröße, natürlicher Erschwernis und Wirtschaftsweise auf die Nachhaltigkeit der österreichischen Milchviehhaltung
Provedor de dados: 21
Autores: Kirner, Dr. Leopold; Bartel-Kratochvil, Dr. Ruth.
Diese Arbeit geht der Frage nach, inwieweit die Merkmale Erwerbsart, Betriebsgröße, natürliche Erschwernis und Wirtschaftsweise die Nachhaltigkeit der österreichischen Milchviehhaltung beeinflussen. Geprüft wird diese Frage mittels Nachhaltigkeitsindikatoren, die dem Netz der freiwillig buchführenden Betriebe im Jahr 2003 entnommen sind. Die Ergebnisse zeigen, dass größere Betriebe und Biobetriebe ein höheres Einkommen erwirtschafteten als kleinere Betriebe und konventionelle Betriebe. Im Rahmen der ökologischen Nachhaltigkeit weisen kleinere Betriebe, Bergbauernbetriebe sowie Biobetriebe tendenziell geringere Umweltbelastungen je Flächeneinheit aus. Demgegenüber konnten in größeren Betrieben, Nicht-Bergbauernbetrieben sowie konventionellen Betrieben...

Einfluss von Futterqualität und Hygienebedingungen auf die Clostridienbelastung in der Milch von Öko-Betrieben in Nordwestdeutschland
Provedor de dados: 21
Autores: Leisen, Edmund.
Im Winter 2001/ 2002 war die Clostridienbelastung in der Milch auf vielen Betrieben höher als in den vorangegangenen Wintern. Im Herbst/Winter 2001/2002 wurden die käsereischädlichen Clostridien in Kot und Milch auf insgesamt 96 Betrieben untersucht. Die Hygienebedingungen ließen sich aus dem Vergleich von Clostridienbelastung in Kot und Milch abschätzen. Zur Ursachenklärung gaben die Betriebe Auskunft über die einzelbetrieblichen Rahmenbedingungen. Zur Einschätzung der Futterqualität standen Futteranalysen sowie eine Beschreibung der Silagequalität zur Verfügung.  Der Grund für die häufig höhere Belastung speziell im Winter 2001/2002 ist auf die witterungsbedingt höhere Clostridienbelastung im Futter zurückzuführen. Positiv wirkten Häckseln und der...

Einfluss von Komposten und Gärgut auf die Bodenfruchtbarkeit
Provedor de dados: 21
Autores: Fuchs, Jacques G.; Berner, Alfred; Mayer, Jochen; Schleiss, Konrad.
Um den Einfluss von Kompost und Gärgut auf die Bodenfruchtbarkeit und auf das Pflanzenwachstum abschätzen zu können wurden hundert, für die Schweiz repräsentative, Proben untersucht.  Die Gehalte an Nährstoffen und an Salz waren vom Ausgangsmaterialien abhängig. Die Gehalte an organischer Substanz sowie die Atmungs- und Enzymaktivitäten nahmen mit zunehmender Kompostreife ab. Bei einigen jungen Komposten konnten Stickstoffblockaden beobachtet werden. Der Nitratgehalt im Kompost erlaubt jedoch vorherzusagen, ob eine N-Immobilisierungsgefahr besteht oder nicht. Die Phytotoxizität der Komposte variierte auch bei den reiferen Produkten sehr stark. Dies weist auf die grosse Bedeutung der Rotteführung und der korrekten Lagerung der Produkte hin. Während die...

Einfluss von Luzernebeständen auf den mikrobiellen Kohlenstoff und Stickstoff in der Ackerkrume und im Unterboden im pannonischen Klimaraum Ostösterreichs
Provedor de dados: 21
Autores: Friedel, Jürgen K; Farthofer, Renate; Pietsch, Gabriele; Freyer, Bernhard.
In ostösterreichischen Ackerbaugebieten ist auch im Ökologischen Landbau die viehlose Bewirtschaftungsform üblich. Der Hauptanteil des Stickstoffbedarfes wird über den Einsatz von Futter- und Körnerleguminosen sowie Leguminosen im Zwischenfruchtanbau gedeckt. Die Nutzung von Futterleguminosen erfolgt als Gründüngung, bei der der Aufwuchs am Feld verbleibt (Mulch). Die Leguminose wird als Reinkultur oder im Gemenge mit Gras angebaut. Es sollte geklärt werden, ob durch die Wurzelmasse und das tiefreichende Wurzelsystem unter Futterleguminosenbeständen die mikrobielle Biomasse bereits nach einmaligem, überjährigen Anbau von Leguminosen, v.a. im Unterboden, gefördert wird. Weiters wurde untersucht, ob Unterschiede aufgrund der Art des Nutzungsregimes (Mulch...

Einflussfaktoren auf den Bekämpfungserfolg beim Hacken
Provedor de dados: 21
Autores: Laber, Hermann; Stützel, Hartmut.
Erhebungen in Praxisbetrieben und Feldversuche haben bei den gleichen Kulturen - Möhren und Zwiebeln - enorme Unterschiede im Bekämpfungserfolg durch Hacken gezeigt (Gemüse Nr. 10/98 - siehe www.orgprints.org/00001192). So konnten in einigen Fällen im Zwischenreihenbereich Bekämpfungserfolge von 100% und selbst im Reihenbereich von nahezu 80% gefunden werden, wo hingegen in anderen Fällen deutlich schlechtere Ergebnisse erzielt wurden.   Die Ergebnisse der Modell- und Feldversuche verdeutlichen, daß für einen befriedigenden Bekämpfungserfolg beim Hacken vier Punkte beachtet werden müssen:  - Der Boden sollte trocken, höchstens leicht feucht sein.  - mindestens ein Tag nach dem Hacken sollte sonniges, trockenes Wetter herrschen.

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...

Elemental composition and phosphorus availability in hydrochars from seaweed and organic waste digestate
Provedor de dados: 21
Autores: Løes, Anne-Kristin; Sandquist, Judit; Meyer, Gregor.
By hydrothermal liquefaction (HTL) of organic matter, hydrochars are produced which may be applied to soil for carbon sequestration. From substrates of wild seaweed and organic waste digestate, we measured the distribution of solids (hydrochars) and liquids after HTL at 150 and  200°C, 50 bar for 1 h. The output of liquids and solids was recorded. Elemental analysis was conducted for essential plant nutrients, potentially toxic elements (PTEs) and silicon in the hydrochars. Sequential extraction of phosphorous (P) was conducted to assess the P availability  for plants. About 20% of the initial dry matter dissolved during HTL of digestate, and 55% for seaweed. More dry matter was dissolved by increased temperature. Except from arsenic in seaweed chars, the...

Eleven years with organic dairy production in Denmark – herd health and production related to time of conversion and compared to conventional production
Provedor de dados: 21
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...

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...

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...

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...

The emergence behaviour of weed species in relation to cultural and meteorological events was studied.  Dissimilarities between populations in dormancy and germination ecology, between-year maturation conditions and seed quality and burial site climate, all contribute to potentially unpredictable variability.  Therefore, a weed emergence data set was produced for weed seeds of Stellaria media and Chenopodium album matured and collected from three populations (Italy, Sweden and UK).  The seeds were collected in two consecutive seasons (1999 and 2000) and subsequently buried in the autumn of the same year of maturation in eight contrasting climatic locations throughout Europe and the USA. The experiment sought to explore and explain differences between the...

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...

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...

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...

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...

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...

Empowered by stigma? Pioneer organic farmers' stigma management strategies
Provedor de dados: 21
Autores: Lähdesmäki, Merja; Siltaoja, Marjo; Luomala, Harri; Puska, Petteri; Kurki, Sami.
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. Our study increases the understanding of the institutionalization process of organic farming by demonstrating how pioneer organic...

Energy analysis of organic crop systems. Impact of intensification level.
Provedor de dados: 21
Autores: COLOMB, B.; GLANDIERES, A.; CARPY-GOULARD, F.; LECAT, N.; PELLETIER, A.; PRIEUR, L.
This study reveals a wide variability in the major parameters of the energy analysis applied to 44 four-year-long organic crop sequences. The intensification level of the systems in terms of the use or nonuse of organic fertilisation on cereals and of irrigation on summer crops (mainly pulses) is largely responsible for this variability. Average energy consumption ranges from 5 000 to 12 270 MJ/ha/year depending on the intensification level. Energy production varies from 35 500 to 43 950 MJ/ha/year. Since energy consumption and production both vary in the same direction with the degree of intensification, the energy gain is stable at an average value of 29300 MJ/ha/year. Energy efficiency decreases from 7.1 MJ/MJ for unfertilised and unirrigated crop...

Autores: Liu, Y.; Langer, Vibeke; Høgh-Jensen, Henning; Egelyng, Henrik.
The development of organic protected cultivation taking place in densely populated areas has raised the question whether it is an environmentally friendly production system. The present study investigated energy consumption of organic pear production in two production systems, namely in traditional Chinese solar greenhouse and in the open field. In both production systems, energy output/input ratio and energy productivity were used as indicators to determine the energy efficiency; yield, cost of production, net economic return pear land area unit and benefit/cost ratio were used to evaluate economic productivity. The analysis results indicated that energy input and energy output in the solar greenhouse were higher than in open field per land area; whereas...

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: 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...

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...

Autores: Liu, Yuexian; Langer, Vibeke; Høgh-Jensen, Henning; Egelyng, Henrik.
The objective of this study was to evaluate the differences in the energy consumption between the production of certified organic pear, green food certified pear, and conventional pear in two areas in China. Data were collected from interviews with farmers during 2007 and 2008. Energy inputs were significantly higher in organic systems compared with conventional and green systems. Fertilizer was the most important contributor to energy consumption in all three farming systems. Three calculation methods for energy value of manure have been found in the literature: substitution method, by-product method, and thermal method. The choise of various calculation methods for estimating the energy value of manure turns out to have great influence on the results in...

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...

Autores: Meyling, Nicolai V.; Navntoft, Søren; Philipsen, Holger; Thorup-Kristensen, Kristian; Eilenberg, Jørgen.
Population dynamics of the cabbage root fly Delia radicum in three different organic and one conventional cabbage cropping systems were evaluated over 3 years. Oviposition was reduced over time, but not affected by organic farming practice. Pupal production was reduced in all organic systems compared to the conventional system in all years, but pupal parasitation rates were similar among systems. More predators of fly eggs were present in the organic system O2. Reduced larval survival rates in the organic systems may be result of increased natural enemy activity and plant effects.

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.

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.

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...

Entropy of energy crops and GHG mitigation
Provedor de dados: 21
Autores: Schäfer, Winfried.
The photosynthesis process generates beside carbon hydrates also complex chemical compounds. The artificial synthesis of such compounds is often impossible or may require high energy input compared to their heat value. In other words, the entropy of energy crops is low compared to fossil fuels. This fact is usually neglected in energy analysis of bio fuels resulting in questionable political decisions concerning renewable energy. The objective of this paper is to demonstrate that the GHG mitigation potential of e.g. fibre crops may be enhanced using them first as raw material for commercial products before processing to fuel at the end of their lifetime. For example, reed canary grass may be used for paper production and after recycling, the used paper can...

Entwicklung der Grundnährstoffgehalte und des pH-Wertes im Boden nach 10-jähriger Bewirtschaftung nach den Richtlinien des ökologischen Landbaus
Provedor de dados: 21
Autores: Gruber, Harriet; Thamm, Uwe.
The following paper shows the impact of organic farming on the development of contents of phosphorus, potassium, magnesium and pH in the soil. The basis is a six-year crop rotation with animal manures (ca. 85 dt/ha/a) in the location of Gül-zow (Mecklenburg-Prepomerania). From 1993 to 2003 samples of soil were taken with aa soil auger in a depth between 0 and 30 cm. The discussion of changes in the nutrient contents are connected with nutrient balances. As a re-sult, organic farming does notnot lead to lower nutrient contents in soil. Only the content of potassium shows a decreasing tendency. The pH is atat a high level and the content of magnesium increases a little.   --  (Sprache des Volltextes: Deutsch)

Entwicklung und politische Rahmenbedingungen des ökologischen Landbaus in Europa
Provedor de dados: 21
Autores: Lampkin, Nic; Padel, Susanne; Foster, Carolyn.
Der Beitrag schildert die Entwicklung und politischen Rahmenbedingungen des ökologischen Landbaus in der EU, wo er in den letzten Jahren aufgrund einer Reihe von Faktoren stark zugenommen hat. Politische Maßnahmen in den Bereichen direkte Flächenförderung zur Umstellung und Beibehaltung des ökologischen Landbaus, staatlich anerkannte Richtlinien und Förderung der Marktstruktur, Regionalentwicklung, Beratung und Forschung werden betrachtet. Dabei zeigt sich, dass einzelne Maßnahmen entgegengesetzt wirken können. In einigen Ländern wurden gute Erfahrungen mit integrierten Aktionsplänen gemacht, ein Weg, der jetzt auch auf europäischer Ebene diskutiert wird und auch in Zukunft dem ökologischen Landbau günstige Rahmenbedingungen schaffen könnte.

Stellt man Nichtfachleuten die Frage, wie die aktuellen ökologischen Probleme unserer Gesellschaft zu lösen sind, kommt es zu zwei typischen Antworten. Heilmittel sind danach die Veränderung der Anreizstrukturen und die Veränderung sozialer Normen und Werte. Dabei wird von den imaginären Antwortenden auch sehr klar vorgeführt, wer denn sein Handeln und die dazugehörigen Grunddispositionen verändern soll. Es sind die Verbraucher im Allgemeinen, die Politik und die Industrie.  Ein zentrales Thema der Umweltsoziologie ist die kulturelle Wahrnehmung von sozial produzierten Umweltproblemen und die Analyse der entsprechenden Reaktionen zur Lösung dieser Probleme. Im Bereich Landwirtschaft werden in dieser Hinsicht die Änderungen der Agrarstruktur, Emissionen,...

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...

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...

Environmental assessment tools for the evaluation and improvement of European livestock production systems
Provedor de dados: 21
Autores: Halberg, Niels; van der Werf, Hayo M.G.; Basset-Mens, Claudine; Dalgaard, Randi; de Boer, Imke J.M.
Different types of assessment tools have been developed in Europe with the purpose of determining the environmental impact of various livestock production systems at farm level. The assessment tools differ in terms of which environmental objectives are included and how indicators are constructed and interpreted. The paper compares typical tools for environmental assessment of livestock production systems, and recommends selected indicators suitable for benchmarking. The assessment tools used very different types of indicators ranging from descriptions of farm management and quantification of input to estimates of emissions of, e.g., nitrate and ammonia. The indicators should be useful in a benchmarking process where farmers may improve their practices...

Environmental Growing Conditions in Five Production Systems Induce Stress Response and Affect Chemical Composition of Cocoa (Theobroma cacao L.) Beans
Provedor de dados: 21
Autores: Niether, Wiebke; Smit, Inga; Armengot, Laura; Schneider, Monika; Gerold, Gerhard; Pawelzik, Elke.
Cocoa beans are produced all across the humid tropics under different environmental conditions provided by the region but also by the season and the type of production system. Agroforestry systems compared to monocultures buffer climate extremes and therefore provide a less stressful environment for the understory cocoa, especially under seasonally varying conditions. We measured the element concentration as well as abiotic stress indicators (polyamines and total phenolic content) in beans derived from five different production systems comparing monocultures and agroforestry systems and from two harvesting seasons. Concentrations of N, Mg, S, Fe, Mn, Na, and Zn were higher in beans produced in agroforestry systems with high stem density and leaf area...

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...

Environmental impacts of organic and conventional agricultural products - Are the differences captured by life cycle assessment?
Provedor de dados: 21
Autores: Meier, Matthias S.; Stoessel, Franziska; Jungbluth, Niels; Juraske, Ronnie; Schader, Christian; Stolze, Matthias.
Comprehensive assessment tools are needed that reliably describe environmental impacts of different agricultural systems in order to develop sustainable high yielding agricultural production systems with minimal impacts on the environment. Today, Life Cycle Assessment (LCA) is increasingly used to assess and compare the environmental sustainability of agricultural products from conventional and organic agriculture. However, LCA studies comparing agricultural products from conventional and organic farming systems report a wide variation in the resource efficiency of products from these systems. The studies show that impacts per area farmed land are usually less in organic systems, but related to the quantity produced impacts are often higher. We reviewed 34...

Environmental life cycle assessment of organic grass protein from multispecies mixtures
Provedor de dados: 21
Autores: Knudsen, Marie Trydeman; Dorca-preda, Teodora; Djomo, Sylvestre Njakou; Kristensen, Troels; Ambye-Jensen, Morten; Møller, Henrik B.; Dupont, Y.L.; Cong, W-F; Eriksen, Jørgen.
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...

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...

Er der krummer i din jord – eller er det bare knolde
Provedor de dados: 21
Autores: Elmholt, S.; Schjønning, P.; Munkholm, L.J.
Jordens krummer er vigtige for vækst. Både vækst af afgrøden og de svampe og bakterier, der laver bindemidler til nye krummer. Vi har undersøgt, hvordan praktisk økologisk og konventionel drift påvirker dette samspil. Et varieret sædskifte med meget græs og husdyrgødning gav gode stabile krummer med højt indhold af biologiske bindemidler. Et ensidigt kornsædskifte med kunstgødning gav i stedet stabile knolde, hvor bindemidlet var ler. Sådan nogle knolde kan give et dårligt såbed, fordi våd jord bliver blød som mudder og tør jord hård som beton.

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.

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.

Die in den Jahren 2009 und 2010 vorgenommenen Beprobungen waren konzipiert, eine Übersicht über die Kupfergesamtgehalte in den deutschen Weinanbau­ge­bieten zu erhalten. Die damit gewonnene Datengrund­lage kann sowohl weiteren spezifischeren Erhebungen als auch der Festlegung von Dauerbeobachtungsflächen dienen und ist Voraussetzung für die Auswahl von Flächen zur Untersuchung der Auswirkungen der Kupferbelastungen auf das Bodenleben im Sinne des Strategie­papiers zum Einsatz von Kupfer als Pflanzenschutzmittel in der Landwirtschaft unter besonderer Berücksichtigung des ökologischen Landbaus.  Insgesamt wurden 2087 Einzelproben aus den Bodenhorizonten bis 5 cm und bis 20 cm von 85 Reblagen an konventionell und ökologisch bewirtschafteten Stand­orten unter...

Autores: Molkentin, Joachim.
Aufgrund der deutlichen Handelspreisdifferenz sowie des begrenzten Rohstoffangebots erhöht der boomende Markt für Biolebensmittel die Gefahr der Falschdeklaration konventioneller Ware. Zum Schutz der Konsumenten wie auch der Produzenten werden daher Verfahren zur Überprüfung der Kennzeichnung benötigt, die – in Ergänzung der betrieblichen Kontrollen – im Zweifelsfall eine Unterscheidung biologisch und konventionell erzeugter Lebensmittel auf Ebene des Detailhandels erlauben.

Ernesto Genoni: Australia’s pioneer of biodynamic agriculture
Provedor de dados: 21
Autores: Paull, John.
Ernesto Genoni (1885-1975) pioneered biodynamic agriculture in Australia. In 1928 he was the first of (ultimately) twelve Australians to join Rudolf Steiner’s Experimental Circle of Anthroposophical Farmers and Gardeners (ECAFG) which was based at the Goetheanum, Dornach, Switzerland. Ernesto trained as an artist for five years at Milan’s prestigious Brera Academy. He visited his brothers in Australia, broad-acre immigrant farmers in Western Australia, in 1912 and 1914 and during these visits he worked on their, and other’s, farms. In 1916 he enlisted in the Australian Imperial Force (AIF) and served as a stretcher bearer on the battlefields of the Somme, France, before being conscripted into the Italian Army and serving jail-time in Italy as a draft...

Autores: Bohne, Heike; Andrea, Bremer; Michaelis, Jan-Peter.
Nach neunjähriger Umstellungszeit von konventionellem Ackerbau zu ökologischer Baumschulwirtschaft und Abfuhr des Aufwuchses waren die Nmin-Gehalte im Boden bei der folgenden Baumschulkultur niedriger als nach einjähriger Umstellungszeit. Im letzten Fall wäre die Stallmistgabe vor der Kultur nicht nötig gewesen.  Eine große Standweite (31250 Pfl./ha) führte bei Rhamnus catharticus, Rhamnus frangula und Corylus avellana zu  höherer Triebanzahl und Gesamttrieblänge und zu einem größeren Sproß-zu-Wurzel-Verhältnis im Vergleich zu einer kleineren Standweite (62500 Pfl./ha). Abgesehen von Rh. catharticus war der N-Entzug bei der größeren Standweite kleiner als bei der kleineren Standweite. Bei gleichem N-Angebot führt die größere Standweite daher zu einer...

Ertragswirksamkeit der Restverunkrautung in Gemüsekulturen nach nichtchemischen Unkrautregulationsmaßnahmen
Provedor de dados: 21
Autores: Laber, Hermann; Stützel, Hartmut.
Um Ertrags- und Qualitätseinbußen zu vermeiden, müssen Gemüsekulturen weitgehend unkrautfrei gehalten werden. Während im Zwischenreihenbereich dieses Ziel mit mechanischen Regulationsmaßnahmen durchaus erreicht werden kann, ist der Bekämpfungserfolg im Reihenbereich der Kulturpflanzen häufig unzureichend. Die hier verbleibenden Unkräuter können bei konkurrenzschwachen Kulturen zu hohen Ertragsausfällen führen.  In den vorliegenden Untersuchungen wurden die Wirkungen der Verunkrautung, die nach thermischen und mechanischen Regulationsmaßnahmen in Möhren-, Zwiebel- und Blumenkohlbeständen verblieb, in Praxisbetrieben und, mit breiterer Variation der Verfahren, auf der Versuchsstation quantifiziert. Auf den Praxisbetrieben wurde das Ziel, unkrautbedingte...

Establishing references to optimise organic fertilisation in organic rice farming in  the Camargue region of France
Provedor de dados: 21
Autores: MOURET, J-C.; HAMMOND, R.; BAYOT, M.; FABRE, D.; THOMAS, C.
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.

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...

Estimating legume N2 fixation in a grass-clover mixture of grazed organic cropping systems using two 15N methods.
Provedor de dados: 21
Autores: Vinther, Finn P.; Jensen, Erik S.
The input of N through symbiotic N2 fixation (SNF) in grass-clover mixtures was determined in an organic cropping system for grazing during three years. The mixture of perennial ryegrass (Lolium perenne L.) and white clover (Trifolium repens L.) was established by undersowing in spring barley (Hordeum vulgare L.) and maintained subsequently for two production years. Dinitrogen fixation was determined using the 15N isotope dilution techniques and two labelling procedures. Using either pre-labelling of the soil with immobilisation of the 15N by addition of a carbon source before establishment of the grass-clover mixture or adding the 15N labelled ammonium to the established crop, resulted in similar estimates of the proportion of N derived from the...

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.

Um dos fatores mais limitantes para a produção de vermicomposto é a disponibilidade de esterco. Neste trabalho, foi avaliado o efeito da substituição parcial do esterco por bagaço de cana e por resíduos de leguminosa (Gliricidia sepium) na vermicompostagem sobre a qualidade do vermicomposto e sobre a bioatividade dos humatos, avaliadas por meio da análise do crescimento radicular e da atividade das bombas de H+ isoladas de raízes de alface. A substituição do esterco por bagaço de cana e por resíduos de leguminosas não acarretou prejuízo às características químicas dos vermicompostos. No entanto, os humatos isolados  dos diferentes vermicompostos apresentaram características químicas distintas,tais como: acidez e propriedades óticas distintas. Os humatos...

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...

Ethical food standard schemes and global trade: Challenging the WTO?
Provedor de dados: 21
Autores: Daugbjerg, Carsten; Botterill, Linda.
Global food trade embodies a range of different  interpretations of the nature of food and its role in society.  On the one hand, the WTO food regulation regime, in particular the SPS agreement, is based upon a somewhat instrumental value of food consumption in which food is seen as a commodity to be traded in accordance with international trade rules.  At the same time, a number of private standards, such as GlobalG.A.P and various organic standards, are emerging which embody broadly postmaterialist values that suggest that food purchasing and consumption are also social, ethical and perhaps even political activities. This paper analyses the relationship between the WTO food trade regime on the one hand and the GlobalG.A.P and organic food trade regimes...

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...

An in-house library of more than 3000 extracts of plant and fungal origin was screened against some major plant pathogens. As one of the hits, an ethyl acetate extract from inflorescences of Verbesina lanata showed significant inhibitory activity in vitro against grapevine downy mildew (Plasmopara viticola), with a MIC100 value of 35 μg/mL. An emulsifiable concentrate formulation with 50 mg/g of the extract was developed for in vivo evaluation. A suspension of the formulation containing 1 mg/mL of extract lowered leaf surface infection of grapevine seedling by 82% compared to the nontreated control. With the aid of HPLC-based activity profiling, the antifungal activity was correlated with a series of lipophilic compounds. Preparative isolation by a...

European perspectives of organic plant breeding and seed production in a genomics era.
Provedor de dados: 21
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...

Reliable assessments of how human activities affect  wildlife populations are essential for effective natural resource management. 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...

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...

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...

Evaluating pea and barley cultivars for complementarity in intercropping at different levels of soil N availability
Provedor de dados: 21
Autores: Hauggaard-Nielsen, Henrik; Jensen, Erik Steen.
Two field experiments were carried out on a temperate sandy loam using six pea (Pisum sativum L.) and five spring barley (Hordeum vulgare L.) cultivars to determine cultivar complementarity in the intercrop for grain yield, dry matter production and nitrogen (N) acquisition. Crops were grown with or without the supply of 40 or 50 kg N ha-1 in the two experiments. Cultivars were grown as sole crops (SC) and as mixed intercrops (IC) using a replacement design (50:50). 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 cultivar performance in intercropping relative to sole cropping.  Barley was the stronger competitor in the...

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...

Evaluation of 14 Old Unsprayed Apple Varieties
Provedor de dados: 21
Autores: Kühn, Birka Falk; Pedersen, Hanne Lindhard.
The performance of 14 old apple varieties planted in three experimental plots was evaluated over four or five seasons. The yield and fruit size were recorded on conventionally grown trees. The level of disease and pests on trees and fruits was estimated in an organically grown unsprayed plot, and the eating quality was evaluated in an unsprayed experimental plot. Large differences in yield and fruit size were found between varieties. It was demonstrated that Holsteiner Cox was the only variety that combined high yield, good fruit size and good eating quality with an acceptably low susceptibility to disease. Most varieties had poor eating quality.  ‘Holsteiner Cox’ had a medium susceptibility to canker and powdery mildew, while susceptibility to apple scab...

Provedor de dados: 21
Autores: Schader, Christian; Lampkin, Nicolas; Christie, Michael; Nemecek, Thomas; Gaillard, Gérard; Stolze, Matthias.
The economic efficiency of financial support of organic farming has been questioned by economists and policy makers. However, little empirical research has been done in order to evaluate the economic performance of these payments. Thus, the aim of this paper is to calculate the cost effectiveness of organic farming support in achieving environmental policy targets compared to other agri-environmental measures. The cost-effectiveness of agri-environmental measures can be understood as a function of policy uptake, environmental effects, and public expenditure. Taking the Swiss agricultural sector as an empirical case study, cost-effectiveness of organic farming support and other single agri environmental measures was calculated. For this purpose, the...

Autores: Hauggaard-Nielsen, Henrik; Johansen, Anders; Carter, Mette S.; Ambus, Per; Jensen, Erik Steen.
To enhance integrity of organic farming it is important not only to deliver high quality food products to a growing market but also to include strategies to reduce the reliance on fossil fuels and decrease total greenhouse gas emissions. In this context, the increased use of perennials within traditionally more annual-based rotations may gain significant importance. The objective of this study was to determine the effect of a strip cropping strategy combining intercropping of a grass-clover based perennial forage crop mixture (soil fertility building (SFB) crop) and maize in strips on the biomass productivity per land area and to determine interactions between strip border rows and associated mechanisms responsible for a potentially improved resource use...

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.

Evaluation of three tools for assessing infection by gastrointestinal parasites in pasture-fed organic lambs
Provedor de dados: 21
Autores: BOUILHOL, M.; CABARET, C.; FOESSEL, M.
Organic meat sheep producers have a very limited array of efficient alternative drugs and limited access to synthetic drugs for controlling internal parasites. The use of targeted selective treatments, e.g., treating only the lambs that cannot cope with infection, would be of interest. The difficulty is to identify those lambs in need of treatment. FAMACHA© (based on an anaemia indicator) has been used with success in tropical areas where the bloodsucker worm Haemonchus contortus is the main gastrointestinal strongyle. The appearance of the wool is sometimes used to determine the necessity of treatment, and a spectrofluorometric analysis of the wool was tested. Shepherds may also detect lambs with poor, medium and good body conditions, on the basis of...

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...

Evaluation Ökomassnahmen: Biodiversität. Effekte ökologischer Ausgleichsflächen auf die Laufkäferfauna
Provedor de dados: 21
Autores: Pfiffner, Lukas; Luka, Henryk; Jeanneret, Philippe; Schüpbach, Beatrice.
Haben ökologische Ausgleichsflächen positive Effekte auf die Laufkäferfauna? In zwei unterschiedlich genutzten Landschaften sind wir dieser Frage nachgegangen. Die Ergebnisse des ersten Erhebungsjahres 1997 zeigen, dass die Arten- und Individuenzahlen der Laufkäfer innerhalb der gleichen Lebensraumtypen stark variieren können. Dies kann teils auf die Qualität dieser Elemente sowie auf Standortverhältnisse und Landschaftseinbettung zurückgeführt werden. Im Ackerbaugebiet wurden mit ökologischen Ausgleichsflächen insbesondere mit Buntbrachen deutlich positive Auswirkungen auf die Laufkäfer erzielt. Die wenig intensiv und extensiv genutzten Wiesen im Futterbaugebiet hingegen unterschieden sich weniger deutlich von den intensiv genutzten Wiesen und Weiden....

Evaluierung von Saflor- und Leindotter-Genotypen zur Nutzung als Ölpflanze im Ökologischen Landbau
Provedor de dados: 21
Autores: Reinbrecht, Dr. C.; Becker, H.C.; von Witzke-Ehbrecht, S.; Claupein, W.
Im Ökologischen Landbau fehlt bislang eine geeignete Ölpflanzenart, deren Samen als Rohstoff für die Speiseölerzeugung dienen können. Raps und Sonnenblumen bieten aufgrund der Schädlingsproblematik, des hohen N-Bedarfes bzw. durch die geringe ökologische Adaptation keine günstigen Voraussetzungen für den Anbau. 2002 wurden in einer zweiortigen Prüfung auf Mikroparzellen unter insgesamt nahezu 1000 Genotypen (Genbank-Akzessionen, Sorten, Zuchtstämme) von Saflor und Leindotter als alternative Arten geeignete Formen für den Anbau gesucht. Die Ergebnisse zeigen, dass beide Arten hinsichtlich ihrer Anfälligkeit für verschiedene Krankheiten und anderer agronomisch relevanter Merkmale hohe genotypische Variation aufweisen, welche direkt im Anbau oder aber als...

Provedor de dados: 21
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...

Evidence for denitrification as main source of N2O emission from residue-amended soil
Provedor de dados: 21
Autores: Li, Xiaoxi; Sørensen, Peter; Olesen, Jørgen E.; Petersen, Søren O.
Catch crops, especially leguminous catch crops, may increase crop nitrogen (N) supply and decrease environmental impacts in cropping systems, but they may also stimulate nitrous oxide (N2O) emissions following spring incorporation. In this 28-day laboratory incubation study, we examined the carbon (C) and N dynamics and N2O evolution after simulated incorporation of residues from three catch crop species into a loamy sand soil, with variable soil moisture (40, 50 or 60% water-filled pore space (WFPS)). The catch crops include two leguminous (red clover and winter vetch) and one non-leguminous species (ryegrass). Plant material was placed in a discrete layer surrounded by soil in which the nitrate (NO3-) pool was enriched with 15N to distinguish N2O derived...

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...

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...

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...

Examples of alien pathogens in Finnish potato production - their introduction, establishment and consequences
Provedor de dados: 21
Autores: Hannukkala, Asko O.
Most pathogens on potato have been imported into Finland via contaminated seed more than hundred years ago. The history of migration and the consequences for potato production of potato wart, blackleg and soft rot, Potato mop-top virus (PMTV) and its vector powdery scab are reviewed as examples of economically important and biologically different potato pathogens. Potato wart spread alarmingly during 1920-1960. Plant quarantine acts and the use of resistant cultivars were successful in eradicating the disease. The pathogens causing blackleg and soft rot increased rapidly in 1960-1970. Development of seed certification schemes after the end of the 1970s decreased disease incidence and made the disease insignificant other than for seed potato production....

Exchangeable potassium and potassium balances in organic crop rotations on a coarse sandy soil
Provedor de dados: 21
Autores: Askegaard, Margrethe; Eriksen, Jørgen; Olesen, Jørgen E.
Crops on sandy soils (&lt;5% clay) are exposed to K deficiency due to the small release and high leaching losses of K. Reliable tools are needed to improve the K management in cropping systems with limited K input, such as organic farming where import of nutrients are restricted according to the EC regulations. We investigated K balances and exchangeable K (Kexch) changes in an organic crop rotation experiment. Potassium leaching decreased from 42 kg ha-1 in 1998/99 to 21 kg ha-1 in 2000/01 as an average of a crop rotation (spring barley, grass-clover, winter wheat and pea/barley) with manure application and without catch crops. In the same period, spring Kexch decreased from 5.0 to 3.0 mg K 100 g-1 soil (0-20 cm). The retention of the straw K left in the...

Exchangeable potassium in soil as indicator of potassium status in an organic crop rotation on loamy sand.
Provedor de dados: 21
Autores: Askegaard, Margrethe; Eriksen, Jørgen.
In organic agriculture, where K may be a limited resource, reliable tools are important in the assessment of K availability in the soil in order to avoid K deficiency.  We investigated the effect of four organic farming systems on the exchangeable K in the plough layer of a six-course crop rotation from 1994 to 1997. The accumulated K balances over the four years varied between   -49 and  +120 kg K ha-1 and the corresponding exchangeable K (0-20 cm) in autumn 1997 was 7.1 and 9.6 mg K 100 g soil-1, respectively, as an average of the crop rotation. The exchangeable K fraction responded to the K application in manure and to the crop in the rotation. In an additional experiment, no yield response to K was found, despite a low level of exchangeable K. The...

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. Feedback from the groups was obtained for 36 'tools', defined as end-user materials, such as technical guides, videos on websites informing about practices in organic...

B vitamins, such as thiamine and riboflavin, are often supplemented in diets for farm animals to prevent deficiencies. However, information on the content of these two B vitamins in organic feedstuffs is scarce. Recently, up-to-date information was published by our group. The objective of this work was to use present data to determine the native contents of thiamine and riboflavin in diets used for monogastric animal feeding in organic farming.   We used the results of our recent study on the native thiamine and riboflavin contents of organic wheat (Triticum aestivum L.), rye (Secale cereale L.), triticale (Triticosecale L.), barley (Hordeum vulgare L.), oats (Avena sativa L.), field peas (Pisum sativum L.), field beans (Vicia faba L.), and blue lupins...

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...

Expected Crop Yield Loss When Converting to Organic Dairy Farming in Denmark
Provedor de dados: 21
Autores: Halberg, N.; Kristensen, I. Sillebak.
Knowledge of differences between organic and conventional crop yields is of interest for farmers, advisors, politicians and research scientists. Based on collected data from Danish organic and conventional mixed dairy farms the yield difference was estimated to be 21-37% in grain crops and 12-18% in fodder beets and grass/clover depending on climatic conditions and soil type. A method is presented to correct for the influence of year and geographic differences using crop and farm-specific simulated potential yields as regression variables in a linear statistical model. An interaction between potential yield and farming system indicates that other growth factors, possibly nutrients, are limiting the yields on organic farms more than on conventional farms....

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: 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,...

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...

Autores: Erb, Karl-Heinz; Lauk, Christian; Kastner, Thomas; Mayer, Andreas; Theurl, Michaela C.; Haberl, Helmut.
Safeguarding the world’s remaining forests is a high priority goal. We assess the biophysical option space for feeding the world in 2050 in a hypothetical zero deforestation world. We systematically combine realistic assumptions on future yields, agricultural areas, livestock feed and human diets. For each scenario, we determine whether the supply of crop products meets the demand and whether the grazing intensity stays within plausible limits. We find that many options exist to meet the global food supply in 2050 without deforestation, even at low crop-yield levels. Within the option space, individual scenarios differ greatly in terms of biomass harvest, cropland demand and grazing intensity, depending primarily on the quantitative and qualitative aspects...

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...

This paper aims to assess the contribution, role, and impacts of the Science-Based Research and Innovation Program (ISRIP) on farmers’ transition to organic production in the Camargue. Focusing on how, and to what extent, research actors have contributed to the innovation pathway, we applied a methods-mix. The Participatory Impact Pathway Analysis (PIPA) was used to uncover complex mechanisms along the innovation process; the Outcome Harvesting method to adapt PIPA to the requirements of an ex-post evaluation, and the Social Network Analysis (SNA) to emphasize actors’ relationships in relation to the development process. We demonstrate that the research has contributed to change by developing co-learning interactions with farmers, although this was not...

Extractability of slurry and fertilizer phopshorus in soil after repeated freezing
Provedor de dados: 21
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...

Extraction of phenolic compounds from organic dried apples:  comparison between conventional, microwave- and ultrasound-assisted extraction methods
Provedor de dados: 21
Autores: Stan, Andreea; Bujor, Oana-Crina; Badulescu, Liliana.
The aim of this study was to compare a conventional assay with microwave- (MAE) and ultrasound- (UAE) assisted extraction methods on the extraction of phenolic compounds from organic dried apples by evaluating the content in catechin, epicatechin, chlorogenic acid and quercitrin. Samples from two apple varieties (Golden Rush and Topaz) were analyzed. Methanol/water (70:30, v/v) was selected as the solvent mixture for the phenolic compounds extractions. The High Performance Liquid Chromatography coupled to diode array detection (HPLC-DAD) were used for the identification and quantification of the respective phenolic compounds. Qualitative analysis revealed similar phenolic profiles in both apple varieties. Whatever extraction method is used, in both apple...

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...

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.

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...

Two experiments were carried out to study the effects of using the new faba bean (Vicia faba L.) cultivar Kontu as a domestic protein source for growing-finishing pigs.In Experiment 1,120 pigs were used with a body weight (BW)of 25–110 kg to study the effects of replacing 0, 25, 50, 75,and 100%of rapeseed meal with faba beans in barley +rapeseed meal based diets. Restrictedly fed grower and finisher diets contained 137–317 and 114–260 g kg–1 faba beans, respectively. A barley +soya bean meal based diet was included as a control. The replacement of rapeseed meal with faba beans exerted a quadratic effect on daily weight gain and on the feed conversion ratio of pigs in the growing period and during total fattening (P &lt;0.05).The growth rate of growing pigs...

Facilitative root interactions in intercrops
Provedor de dados: 21
Autores: Hauggaard-Nielsen, Henrik; Jensen, Erik Steen.
Facilitation takes place when plants ameliorate the environment of their neighbours, and increase their growth and survival. Facilitation occurs in natural ecosystems as well as in agroecosystems. We discuss examples of facilitative root interactions in intercropped agroecosystems; including nitrogen transfer between legumes and non-leguminous plants, exploitation of the soil via mycorrhizal fungi and soil-plant processes which alter the mobilisation of plant growth resources such as through exudation of amino acids, extra-cellular enzymes, acidification, competition-induced modification of root architecture, exudation of growth stimulating substances, and biofumigation. Facilitative root interactions are most likely to be of importance in nutrient poor...

Factoring in the forgotten role of renewables in CO2 emission trends using decomposition analysis
Provedor de dados: 21
Autores: Mohlin, Kristina; Camuzeaux, Jonathan R.; Müller, Adrian; Schneider, Marius; Wagner, Gernot.
This paper introduces an approach for separately quantifying the contributions from renewables in decomposition analysis. So far, decomposition analyses of the drivers of national CO2 emissions have typically considered the combined energy mix as an explanatory factor without an explicit consideration or separation of renewables. As the cost of renewables continues to decrease, it becomes increasingly relevant to track their role in CO2 emission trends. Index decomposition analysis, in particular, provides a simple approach for doing so using publicly available data. We look to the U.S. as a case study, highlighting differences with the more detailed but also more complex structural decomposition analysis. Between 2007 and 2013, U.S. CO2 emissions...

Factors affecting the concentration of Zn, Fe and Mn in herbage from organic farms and in relation to dietary requirements of ruminants
Provedor de dados: 21
Autores: Govasmark, Espen; Steen, Arvid; Bakken, Anne Kjersti; Strøm, Turid; Hansen, Sissel.
To obtain a general picture of the herbage zinc, iron and manganese concentrations and their relation to dietary requirements of ruminants on organic farms, we analysed soil and herbage samples from four regions in Norway. The soil median Zn, Fe and Mn concentrations were 0.18, 13 and 0.84 mg/L, respectively. The herbage median (10th-90th percentile) Zn, Fe and Mn concentrations (mg/kg) in herbage in the first cut were 19 (14-34), 50 (36-88), 34 (22-86) and in the second cut 21 (16-37), 84 (52-171) and 66 (36-205), respectively. The results of mixed model analysis of herbage Zn, Fe and Mn indicate that soil pH, soil texture, soil mineral concentration and botanical composition are the most influencing factors. We conclude that Zn, Fe and Mn did not limit...

Factors correlated with the presence of rodents in outdoor pig farms in Denmark and suggestions for management strategies
Provedor de dados: 21
Autores: Leirs, H.; Lodal, J.; Knorr, M.
The correlation between farm characteristics and the occurrence and importance of rodent pests on outdoor pig farms in Denmark was explored in an extensive questionnaire survey.  Mice occurred on most farms but were only rarely considered a problem, as opposed to rats, which were controlled on more than half of the farms. A series of trapping studies showed a high small-mammal diversity in and around the pigsties. The presence of rats was positively correlated with farm size, the presence of straw stacks near the pigsties and the use of automatic feeders. Rats were considered a problem more often when open drinking basins were used or when feed was stored near the pigsties. The environment of the farm did not play an important role except to some extent...

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...

Factors influencing the conversion to organic farming in Norway
Provedor de dados: 21
Autores: Koesling, Matthias; Flaten, Ola; Lien, Gudbrand.
Determinants of the decision to convert to organic farming methods are examined by applying bivariate analyses and a multinomial logit model to a survey of 1018 Norwegian crop and dairy farmers. The results show that 4% of the conventional respondents plan to convert by 2009, which may imply that the national goal of 10% organically managed area will not be achieved. The analysis indicates that organic farmers, compared to their conventional counterparts, are more likely to have larger farms, more education, be located closer to urban areas, be crop farmers, have 'sustainable and environment-friendly farming' as a goal and hold favourable views about the values of organic farming methods. Even though the farmers who are planning to convert seem to be more...

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....

Factors limiting the grain protein content of organic winter wheat in south-eastern France: a mixed-model approach.
Provedor de dados: 21
Autores: Casagrande, Marion; David, Christophe; Valantin-Morison, Muriel; Makowski, David; Jeuffroy, Marie-Hélène.
Organic agriculture could achieve the objectives of sustainable agriculture by banning the use of synthetic fertilizers and pesticides. However, organic crops generally show lower performances than conventional ones. In France, organic winter wheat production is characterized by low grain protein content. There is a crucial need for better understanding the variability of grain protein content, because millers require batches with values over 10.5% of dry matter. Here, a regional agronomic diagnosis was carried out to identify the limiting factors and crop management practices explaining the variability of grain protein content. The studied field network was a set of 51 organic winter wheat plots in south-eastern France. The mixed-model method was used for...

Autores: Langer, Vibeke; Rohde, Benjamin.
Factors reducing yield of organic white clover seed production were investigated in Denmark. In thirty-six fields from different regions, density of flower heads and their area, and weevils of the genera Apion and Hypera, hatching from flower heads, were assessed. In fifteen of these fields, additional measurements were made in order to calculate potential yield and yieldreducing factors. Flower heads had a mean of ninetytwo florets per head, of which proportionately 0,59 were intact, 0,08 were not pollinated and 0,34 damaged by weevils; 0,16 of the florets contained larvae of Apion species. In intact florets the mean number of seeds was 3,6. Density and size of flower heads were correlated with low density of flower heads leading to significantly more...

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. The objective of the current study...

Pourtant elle ne se situe qu'au 25ème rang mondial en terme de pourcentage de la surface agricole consacrée à l'agriculture biologique, et importe plus de la moitié de sa consommation. Un fort développement de la recherche en ce domaine est réclamé par les associations afin de répondre aux défis écologiques, économiques, énergétiques et sociaux posés à l'agriculture du XXIème siècle. Quelle est exactement la place consacrée à l’agriculture biologique dans la recherche agronomique des différents pays européens ? La reconnaissance de la pertinence de l’agriculture biologique comme domaine de recherche par l'INRA depuis 1999 a-t-elle conduit à une...

Family farmers and major retail chains in the Brazilian organic sector: assessing new development pathways. A case study in a peri-urban district of Sao Paulo
Provedor de dados: 21
Autores: Blanc, Julien.
The expansion of the organic sector in Brazil is seen as a leverage for the social emancipation of the small family farmers. Next to the traditional alternatives circuits of organic food and farming, new powerful capitalistic actors, such as supermarket chains, are rapidly entering the Brazilian organic arena. Can family farming benefit from the development of these “conventional” commercialisation circuits in the organic sector? Research undertaken in 2007, in a green belt rural community of São Paulo, shows how family farmers benefited from the implication of large retail chains in the organic sector and how an economically and ecologically outstanding agriculture may arise from these circumstances. However, we highlight the crucial role played by social...

Får økologiske forbrugere oftere 6 om dagen?
Provedor de dados: 21
Autores: Denver, Sigrid; Christensen, Tove; Krarup, Signe.
Får økologiske forbrugere oftere 6 om dagen?  Ja! 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. Husholdninger med høje økologiforbrug er typisk små – oftest kvinder – har høje uddannelser og er bosiddende i København. Samtidig er den økologiske forbruger en omskiftelig person, som sagtens...

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...

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...

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...

Farm level environmental indicators; are they useful? An overview of Green Accounting Systems for European farms
Provedor de dados: 21
Autores: Halberg, Niels; Verschuur, Gerwin; Goodlass, Gillian.
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...

Farm level factors associated with feather pecking in organic laying hens
Provedor de dados: 21
Autores: Bestman, Monique; Wagenaar, Jan-Paul.
Farm-level factors that could be associated with feather pecking of layers kept in organic farming systems were monitored in 63 flocks from 26 farms located in different areas of The Netherlands. Data on housing and management practices were  collected and plumage damage as a measure of feather pecking was scored at 50 weeks of age or older. No or little plumage damage was found in 18 (29%) flocks, moderate damage in 12 (19%) flocks and severe damage in 33 (52%) flocks. A high percentage of hens in the flock using the outdoor run, a young age at purchase and an increasing number of cockerels present in the flock were found to significantly decrease feather pecking damage at 50 weeks or older. Factors associated with increased usage of the outdoor run were...

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.

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...

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...

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: 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...

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. In 15 environmental and...

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...

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...

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. The objective of the present study was to investigate the influence of botanically different pastures on bovine milk composition and milk susceptibility to oxidation. Two groups of 8 multiparous Norwegian Red dairy cows [mean (standard deviation); 599 (45.1) kg body weight, 73 (15.0) d in milk, 29.9 (2.90) kg milk/d at...

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...

Autores: Marquardt, Svenja; Barsila, Shanker R.; Amelchanka, Sergej L.; Devkota, N.R.; Kreuzer, Michael; Leiber, Florian.
The fatty acid (FA) profile of ghee produced from milk of cattle–yak hybrids grazing five mountain pasture sites along a high-alpine transhumance route in Nepal was analysed. Pastures differed in altitude above sea level(2600–4500 m), time period of being grazed and phytochemical composition of the swards. Additionally, a comparison of ghee from purebred yak and hybrid was performed, with samples produced at two of the sites. Pasture site had a strong effect on almost all FAs. Proportions of oleic, linoleic and a-linolenic acid in ghee were smallest on the highest pasture at 4500 m where the largest condensed tannin concentrations in the forages were found. No systematic site effects were found for c9,t11 conjugated linoleic acid and total polyunsaturated...

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).

Feasibility of risk-based inspections in organic farming: results from a probabilistic model
Provedor de dados: 21
Autores: GAMBELLI, DANILO; Solfanelli, Francesco; Zanoli, Raffaele.
A risk-based inspection system might improve the efficiency of the organic farming certification system and ultimately provide a basis for increased competitiveness of this sector. This requires the definition of an effective inspection procedure that allows statistical evaluation of critical risk factors for noncompliance. In this article, we present a study based on data from selected control bodies in five European countries that is aimed at determining the feasibility of risk-based inspections in the organic sector according to the data that are currently routinely recorded. Bayesian networks are used for identification of the factors that can affect the risk of noncompliance. The results show that previous/concurrent noncompliant behavior explains...

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...

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,...

Feeding mastitis milk to organic dairy calves: effect on health and performance during suckling and on udder health at first calving
Provedor de dados: 21
Autores: Abb-Schwedler, Katharina; Maeschli, Ariane; Boss, Renate; Graber, Hans U.; Steiner, Adrian; Klocke, Peter.
Background  Infection pathways of S. aureus udder infections in heifers are still not well understood. One hypothesis is that calves become infected with S. aureus via feeding mastitis milk. Especially on small-scale farms, pasteurisers are not economic. The purpose of this randomised comparative study was to investigate the influence of feeding milk containing S. aureus genotype B (SAGTB) on the health and development of calves and udder health of the respective heifers. Additionally, a method reducing the bacterial load to obtain safer feeding milk was tested. Thirty-four calves were fed mastitis milk from cows with subclinical SAGTB mastitis. One group was fed untreated milk (UMG). For the other group, milk was thermised at 61°C for one minute (heat...

Feeding trials in organic food quality and health research
Provedor de dados: 21
Autores: Velimirov , A.; Huber, M.; Lauridsen, C.; Rembiałkowska, E.; Seidel, K.; Bügel , S.
Feeding experiments comparing organically and conventionally produced food are performed to assess the overall impact on the animals' health as a model for the effects experienced by the human consumers. These experiments are based on systems research and characterized by their focus on production methods, whole food testing and procedures in accordance with the terms of organic farming. A short review of such experiments shows that the majority of these tests revealed effects of the organically produced feed on health parameters such as reproductive performance and immune responses. Systems research is not just about simple cause-effect chains, but rather about the pluralism of interactions in biological networks; therefore, the interpretation of the...

Feeding weaned piglets and growing-finishing pigs with diets based on mainly home-grown organic feedstuffs
Provedor de dados: 21
Autores: Partanen, Kirsi; Siljander-Rasi, Hilkka; Alaviuhkola, Timo.
In 2000, EU regulations for organic animal production set new guidelines for organic pig feeding requiring that this be based on mainly home-grown organic feedstuffs. Doubts were however raised whether these feeding regimes can maintain good growth performance and carcass quality of pigs. Three experiments were carried out to study different organic feeding regimes in weaned piglets and fattening pigs. In Experiment 1, we evaluated the use of peas and faba beans (0, 120, or 240 g kg-1) in diets for weaned piglets. Piglets fed pea diets performed as well as those fed the control diet, whereas the highest faba bean level resulted in reduced feed intake and growth performance. In Experiment 2, we studied the replacement (0, 33, or 67%) of rapeseed cake with...

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...

Felines Sarcoid bei einer 1-jährigen europäischen Hauskatze ausgelöst durch bovines Papillomavirus Typ 14 in der Schweiz
Provedor de dados: 21
Autores: Kiefer, C.; Tobler, K.; Ramsauer, A.S.; Biegel, U.; Kuehn, N.; Ruetten, M.
Eine einjährige Bauernhofkatze zeigte einen 5 cm grossen Knoten an der linken Nasenöffnung, der aufgrund seiner Lokalisation nur unvollständig entfernt werden konnte. Hinsichtlich der infiltrativ wachsenden, spindelförmigen Proliferation wurde histologisch ein felines Sarkoid diagnostiziert. Die aus dem Gewebe isolierte DNA konnte durch zwei PCRs als solche von bovinem Papillomavirus 14 (BPV-14) identifiziert werden. Die 194 und 549 Basenpaare (bp) langen, amplifizierten Sequenzen waren 99 bzw. 100% identisch mit einer von einem in den USA isolierten Virus, welches mit felinem Sarkoid in Zusammenhang gebracht wurde. Trotz unvollständiger Exzision, ist bis 10 Monate nach der Operation kein Rezidiv aufgetreten.

Fertilizer value and nitrogen transfer efficiencies with clover-grass ley biomass based fertilizers
Provedor de dados: 21
Autores: Benke, Anna Pia; Rieps, Ann; Wollmann, Iris; Petrova, Ioana; Zikeli, Sabine; Möller, Kurt.
In temperate regions, legume-based green manures are a key element of organic rotations.  However, specialized farms lack sufficient mobile organic fertilizers. To gain a better understanding of the N flows and the nitrogen (N) and phosphorus (P) fertilizer value of different clover-grass-based fertilizers (biogas digestate, compost, silage and fresh clover-grass obtained from clover grass ley biomass), we assessed their fertilizer value. Nitrogen and P offtake by the ryegrass was used to assess the shortterm effects. The data were completed using model calculations to assess the field-to-field N-transfer efficiencies and the overall N-transfer efficiencies.  The greatest plant N offtake was achieved with digestates (64%) and the lowest from the compost...

Fertilizer value of urine in pumpkin (Cucurbita maxima L.)cultivation
Provedor de dados: 21
Autores: Pradhan, Surendra K.; Pitkänen, Susanna; Heinonen-Tanski, Helvi.
The fertilizer value of human urine was compared with mineral fertilizer in pumpkin (Cucurbita maxima) cultivation at a dose of 113 kg N ha-1 with no-fertilization used as control. The growth of the vine was better in urine fertilized pumpkins than in mineral fertilized and non-fertilized pumpkins. Total fruit biomass was higher in mineral fertilized plants compared to urine fertilized and non-fertilized pumpkins. Urine fertilized pumpkins may have suffered from lower potassium or higher chloride, thus they produced fewer flowers and fruits. However, total fruit biomass and the number of fruits were slightly higher in urine fertilized plants than in their non-fertilized counterparts, i.e. 17.2 t ha-1 more pumpkin could be produced with urine fertilizer....

Autores: Daniel, Claudia; Wyss, Eric.
Field experiments with foliar applications of Beauveria bassiana ATCC 74040 (product Naturalis-L) were conducted to control the European cherry fruit fly Rhagoletis cerasi Loew (Diptera: Tephritidae), a major pest of cherries in Europe. Naturalis-L was applied at concentrations of 250 ml per 100 l in 7-day intervals during the flight period of R. cerasi.  Flight activity monitored by yellow sticky traps was only slightly affected by treatments. Infection and mycosis of adult cherry fruit flies was shown to be possible under field conditions. Fruit infestation was assessed at harvest. The number of infested fruits was significantly reduced by 65% with foliar applications of Naturalis-L. These results were obtained from five experiments in 2 years with...

Autores: Daniel, Claudia; Keller, Siegfried; Wyss, Eric.
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 applied at a concentration of 5.75x104 CFU/ml. With four applications at seven day intervals the whole flight period of R. cerasi was fully covered. During this period the relative humidity averaged 66.3% (5th June – 6th July), the temperature averaged 20.5°C. Under these conditions only Naturalis-L significantly reduced the number of damaged fruit (efficacy: 69-74%), whereas damaged fruits were not significantly reduced with PreFeRal (efficacy: 27%).

Field biomass as global energy source
Provedor de dados: 21
Autores: Hakala, Kaija; Kontturi, Markku; Pahkala, Katri.
Current (1997–2006) and future (2050) global field biomass bioenergy potential was estimated based on FAO (2009) production statistics and estimations of climate change impacts on agriculture according to emission scenario B1 of IPCC. The annual energy potential of raw biomass obtained from crop residues and bioenergy crops cultivated in fields set aside from food production is at present 122–133 EJ, 86–93 EJ or 47–50 EJ, when a vegetarian, moderate or affluent diet is followed, respectively. In 2050, with changes in climate and increases in population, field bioenergy production potential could be 101–110 EJ, 57–61 EJ and 44–47 EJ, following equivalent diets. Of the potential field bioenergy production, 39–42 EJ now and 38–41 EJ in 2050 would derive from...

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...

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,...

FieldEco – a multi-purpose biologically driven food web model
Provedor de dados: 21
Autores: Axelsen, Jørgen Aagaard; Sønderskov, Mette; Bruus-Pedersen, Marianne; Tybirk, Knud; Eriksen, Jørgen.
We here present a food web model (FieldEco) that has been constructed to simulate complicated eco-system processes in a food web that includes both the soil and above ground ecosystems and connec-tions between them. FieldEco has been designed to work at the species level. The model is driven by climatic input, and both the population dynamics and the interactions between species are simulated according to the ideas presented by Gutierrez (1996).   FieldEco is equipped with a user interface from which it is possible to design an ecosystem of interest from a list of parameterised species. Presently, this list of parameterised species consists mainly of species that are common in Danish agricultural fields, and it is possible to manipulate their biological...

Field-scale spatial variation in yields and nitrogen fixation of clover-grass leys and in soil nutrients
Provedor de dados: 21
Autores: Nykänen, Arja; Jauhiainen, Lauri; Kemppainen, Jukka; Lindström, Kristina.
Biological nitrogen fixation (BNF) plays a crucial role in organic farming and red clover (Trifolium pratense) is cultivated widely in boreal grasslands for BNF. A geostatistical method, model-based kriging, was used to determine the spatial variation in yield, clover content and BNF of clover-grass leys as well as soil chemical properties throughout two fields in 2004-2006. Based on this variation, principal component analysis (PCA) was used to determine the similar patterns of variation. On one location, total dry matter yields of the leys decreased over three production years from 9 700 to 4 100 kg ha-1, clover content from 53 to 26% and BNF from 150 to 40 kg N ha-1, whereas on the other location the yields increased from 6 500 to 7 100 kg ha-1, clover...

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...

Provedor de dados: 21
Autores: Ankamah-Yeboah, Isacc; Nielsen, Max; Nielsen, Rasmus.
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...

Financial relevance of organic farming payments for Western and Eastern European organic farms
Provedor de dados: 21
Autores: Zander, Katrin; Nieberg, Hiltrud; Offermann, Frank.
Organic farming in the European Union has been supported widely since 1994. Against the background of discussions concerning the design and level of organic farming support, and the relevance of organic payments for the economic success of organic farms, the question emerges as to the impact of support payments on the sustainable development of organic farming in Europe. Different databases and methodological approaches have been chosen to demonstrate the role of organic farming payments for the viability of organic farms for selected Western and Eastern European study countries. Economic analyses are based on national farm accountancy data (FADN) in the Western European countries and on ‘typical farms’ in the Eastern European group. As a supplement to the...

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...

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,...

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...

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...

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...

Foliar spraying of vermicompost extracts: effects on fruit quality and indications of late-blight suppression of field-grown tomatoes
Provedor de dados: 21
Autores: Zaller, Johann G.
The effect of foliar sprays with aqueous vermicompost extracts on growth, yields, morphological and chemical fruit quality and natural infection with late blight disease (Phytophthora infestans(Mont.) de Bary)) on three tomato varieties (Lycopersicon esculentum Mill., cv. Diplom F1, cv. Matina, cv. Rheinlands Ruhm) was investigated in a field experiment. Extracts were prepared of vermicompost produced from fruit, vegetable and cotton waste by redworms (Eisenia fetida Sav., Lumbricidae); tap water served as control treatment. Foliar application (spraying) of vermicompost extracts did not affect plant growth, biomass or nutrient allocation, or yields and number of fruits of the three tomato varieties; however, for several dates it significantly reduced the...

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”.

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...

Food and sustainability: local and organic food in Finnish food policy and in institutional kitchens
Provedor de dados: 21
Autores: Risku-Norja, Helmi; Muukka, Eija.
This article probes a number of recent national policy documents in order to capture how sustainability is perceived and expressed in the context of food and what role is given to the alternative food supplies. The goals of food policy and their realization are discussed by reflecting the results from the policy document analysis against the actual use of alternative food in the statutory municipal catering services in Finland. In the policy documents the concept of sustainable development has remained rather abstract; various dimensions such as food security, affordability and access to food, cultural and health aspects are mentioned, but these are not necessarily identified as elements of sustainability. Local and organic foods appear as important items...

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.

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 subsequent quantitative survey (n = 850) tested hypotheses derived from the qualitative research and theoretical literature regarding the...

Food security of small holding farmers: comparing organic and conventional systems in India
Provedor de dados: 21
Autores: Panneerselvam, P.; Hermansen, John E.; Halberg, Niels.
This study compared farm production, crop yield, input cost, and income in organic and conventional farming systems in three states of India: Uttarakhand, Madhya Pradesh, and Tamil Nadu. The results showed that organic farming reduced the input cost without affecting the net margin in all three states. Total food production was found to be comparable for the two systems in two of three states. While yield of rice and wheat generally was lower under the organic systems, yield from intercropping food crops was generally higher. The number of agro-ecological methods and percentage of farms practicing different agro-ecological methods were higher under organic systems than conventional systems. These results suggest that organic farming has the potential to...

Forage cuts as a by-product in organic seed production
Provedor de dados: 21
Autores: Deleuran, L.C.; Boelt, B.
A major problem in organic grass seed production on arable farms is to provide for a sufficient nitrogen supply. A nitrogen-fixing crop may be able to cover the nitrogen requirement - wholly or partly. However mixed cropping of a grass seed and a nitrogen-fixing crop is expected to reduce the establishment of the seed crop, especially for species that require a long establishment period. One way to achieve a satisfactory establishment of the seed crop can be to introduce an intervening year for cutting forage between cover crop harvest and seed harvest. This will enhance tillering, since the light supply for the undersown grass is increased after each cut. However excessive biomass will hinder drying of the crop at maturity and therefore the growth of the...

Provision of an adequate mineral supply in the diets of  ruminants fed mainly on grassland herbage can present a challenge if mineral concentrations are suboptimal for animal nutrition. Forage herbs may be included in grassland seed mixtures to improve herbage mineral content, although there is limited information about mineral concentrations in forage herbs. To determine whether herbs have greater macro- and micromineral concentrations than forage legumes and grasses, we conducted a 2-year experiment on a loamy-sand site in Denmark sown with a multi-species mixture comprised of three functional groups (grasses, legumes and herbs). Herb species included chicory (Cichorium intybus L.), plantain (Plantago lanceolata L.), caraway (Carum carvi L.) and salad...

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...

Forbruget af økologiske varer og ernæringsrigtig kost
Provedor de dados: 21
Autores: Christensen, Tove; Denver, Sigrid; Krarup, Signe.
I Danmark ses i øjeblikket et boom i efterspørgslen efter økologiske fødevarer, der bringer den op på det højeste niveau hidtil. Der kan være mange årsager til denne stigning – eksempelvis menes generelle indkomstløft at være en væsentlig faktor. Igangværende forskning viser desuden, at forbrugerne køber økologiske varer, fordi de forbinder økologi med en lang række positive egenskaber som ren natur, dyrevelfærd, troværdighed, friskhed, kvalitet og sundhed.     Men er der også sammenhæng mellem forbrug af økologiske varer og en ernæringsrigtig kost? Der foreligger ikke entydige forskningsresultater, der bekræfter, at økologiske varianter af den samme vare er et sundere valg. Eksempelvis er risikoen for pesticid- eller medicinrester minimal, mens risikoen...

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...

Forbs enhance productivity of unfertilised grass-clover leys and support low-carbon bioenergy
Provedor de dados: 21
Autores: Cong, W-F; Jing, J; Rasmussen, J; Søegaard, K; Eriksen, J.
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...

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...

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...

Formas sociais de desenvolvimento da horticultura orgânica familiar em áreas de cinturão verde de território de Ibiúna, estado de São Paulo.
Provedor de dados: 21
Autores: Bellon, Stéphane; Abreu, Lucimar Santiago de.
O desenvolvimento da agricultura orgânica (AO) no Brasil tem múltiplas formas. Além de um nicho de mercado ou de uma oportunidade de exportação, consiste numa prática social alternativa, que recria espaços de produção e novas relações entre produtores, mercado e consumidores. Por meio de suas experiências com a AO, em uma comunidade próxima a três metrópoles, horticultores familiares de Ibiúna, SP, criaram entidades coletivas e experimentaram novas práticas sociais. No estudo, mostrou-se como esses minifúndios foram organizados para desenvolver agricultura orgânica e responder a diversos objetivos. Com base nas entrevistas e nas observações de campo, foram consideradas as formas concretas de organização e de desenvolvimento da agricultura orgânica. No...

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...

Forms of Inorganic Phosphorus in Soil under  Different Long Term Soil Tillage Systems and  winter Crops
Provedor de dados: 21
Autores: Tiecher, T.; Santos, D.R.; Kaminski, J.; Calegari, A.
The cultivation of crops with different capacity of P uptake and use under long-term soil tillage systems can affect the distribution of P cycling and inorganic forms in the soil, as a result of higher or lower use  efficiency of P applied in fertilizers. The purpose of this study was to evaluate the effect of long-term cultivation of different winter species under tillage systems on the distribution of inorganic P forms in the soil. In 1986, the experiment was initiated with six winter crops (blue lupin, hairy vetch, oat, oilseed radish, wheat and fallow) on a Rhodic Hapludox in southwestern Paraná, under no-tillage (NT) and conventional tillage (CT ). The application of phosphate fertilizer in NT rows increased inorganic P in the labile and moderately...

Autores: Jokumsen, Alfred.
Den primære proteinkilde i foder til økologiske fisk er fiskemel. Da fiskemel er en begrænset ressource og samtidig ikke er økologisk er der brug for alternativer i form af økologiske vegetabilske proteinkilder. Forskningen er således rettet mod at udskifte en del af fiskemelet med planteprotein bl.a. ved at optimere de økologiske proteinafgrøder med fokus på  de mest kritiske områder i kæden, der forbinder økologisk foderproduktion, økologisk fiskeopdræt og forbrugeren.

Foul Play and the Case of the Organic Eggs
Provedor de dados: 21

The demand for organic food is often reported as exceeding supply. When faced with just such a shortfall in supply, Australian egg supplier G. O. Drew Pty Ltd substituted non-organic eggs to fill the supply gap. That deception has cost the company $295,000, the egg business has been sold, and the owners are no longer egg suppliers or packers.    The 2007 case of ACCC v G. O. Drew Pty Ltd is a milestone for the Australian organic sector - it is the first Australian case where the Australian Consumer &amp; Competition Commission (ACCC) has publicly challenged organic food labelling claims. This compares to at least 16 cases where the ACCC has successfully challenged false and/or misleading Country of Origin labelling (CoOL). Details of the case and...

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....

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.

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.    aus: Haas, G. und Wetterich, F. und Geier, U.

Free-range pigs foraging on Jerusalem artichokes (Helianthus tuberosus L.) – Effect of feeding strategy on growth, feed conversion and animal behaviour
Provedor de dados: 21
Autores: Kongsted, A.G.; Horsted, K.; Hermansen, J.E.
The nutritional contributions from free-range foraging, growth, feed conversion and behaviour were investigated in 36 growing pigs foraging on Jerusalem artichokes (JA) and fed concentrates restrictedly (30% of energy recommendations) or ad libitum. Compared to the ad libitum fed pigs, the pigs fed restrictedly had a significant lower daily gain (560 vs. 1224 g pig_1), improved feed conversion ratio (17.6 vs. 42.8 MJ ME concentrate kg_1 live weight gain) and spent more time foraging JA tubers (7.9 vs. 1.1%). It is estimated that pigs fed restrictedly found approximately 60% of their energy requirement from foraging in the range.

French lag in scientific research on organic farming: a scientometric approach
Provedor de dados: 21
Autores: MOURET, J-C.; HAMMOND, R.; BAYOT, M.; FABRE, D.; THOMAS, C.
France suffers from a large research deficit in most areas related to sustainable development and public health. The case of research on organic farming, within the framework of the broader sector of agronomic research, constitutes a largely under-investigated field. Even if the demand for organic products is rapidly growing in Europe, research in this field still suffers from a lack of funding and researchers.  A bibliometric analysis based on key words from scientific publications (in English only) taken from Thomson Scientific’s ISI Web of Science reference database made it possible to determine sufficiently relevant indicators for a comparison of national research efforts from 2000-2006, and to therefore assess actual research priorities in the area of...

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...

From ‘Additive’ to ‘Multiplicative’ Patterns of Growth.
Provedor de dados: 21
Autores: Schermer, Markus.
Growth processes are often problematic for small-scale farms as they may disturb their delicate balance of basic internal resources, like labor, buildings, machinery, land and animals. Most of these resources cannot be increased in linear processes and the smaller the unit the more problematic the task of realignment of resources becomes. Thus small-scale farmers often feel growth as enforced upon them by outside factors, e.g. a market partners. Growing enterprises in processing and trading need more supply and obviously are not eager to deal with more small suppliers, as this tends to mean higher transaction costs and varying qualities. However, there are examples where dedicated supply chain actors actively engage in preserving small scale structures and...

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...

Autores: Paull, John.
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...

A travers l’exemple du blé dur, les auteurs explorent l’évolution temporelle de la notion d’idéotype mais aussi comment la diversification actuelle des environnements en AB influe sur la diversification des idéotypes et rend nécessaire une démarche dynamique et participative d’amélioration des plantes. Cette façon renouvelée de concevoir et gérer la sélection amène à dépasser la notion d’idéotype, qui reste associée à des critères de sélection a priori, pour préférer le terme de « realtype », qui traduirait la mise à l’épreuve de l’idéotype à la réalité des terrains. Ce n’est donc pas la construction de l’idéotype « par rapport à » mais bien « dans » le contexte qui est recherché et permise par un dispositif collectif représentant la diversité des acteurs...

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,...

From the social to the economical and beyond?: A relational approach to the historical development of Danish organic food networks
Provedor de dados: 21
Autores: Kjeldsen, Chris; Ingemann, Jan Holm.
The organic movement has its roots in a critical attitude  towards the capitalist development of farming and food systems and constitutes in that sense an alternative to conventional food systems. The article aims at exploring which meaning the notions of ‘alternative’ and ‘conventional’ carry, using the historical development of organic food in Denmark as an example. From the 1970s and onwards, organic food networks in Denmark have evolved from being primarily a marginal social movement to becoming included in the market mainstream. The social and spatial settings for organic food networks in Denmark have thus been significantly altered. Using debates on the conventionalisation of organic food systems as the starting point, it is argued in this article...

Urban agriculture is embedded in an urban food system, and its full potential can only be understood by looking into the dynamics of the system.  Involving a variety of actors from civil society, policy, and the market, we conducted a comprehensive analysis of the food system of the city of Basel, Switzerland, including policy and actor analysis, analysis of perceptions on urban agriculture, food flow analysis, and a sustainability assessment. The article presents the results of these analyses and discusses how research can contribute to the societal debate on food systems transformation. We particularly reflect on how the research project became a boundary object in a dynamic process to develop new ideas and activities, as well as to create a space for...

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...

Functional agrobiodiversity – a novel approach to optimize pest control in fruit production
Provedor de dados: 21
Autores: Sigsgaard, Lene.
Fruit growers suffer great economic losses each year due to pest damage. The demand for organic produce is increasing along with the interest from growers to develop sustainable and more resilient production systems and over 20% of the apple production in Denmark is now organic. Available pest management options are limited and prevention is important for resilience. In the project PROTECFRUIT we test the use of functional agrobiodiversity.

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...

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...

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)...

Fungal-mediated multitrophic interactions - do grass endophytes in diet protect voles from predators?
Provedor de dados: 21
Autores: Saari, Susanna; Sundell, Janne; Huitu, Otso; Helander, Marjo; Ketoja, Elise; Ylönen, Hannu; Saikkonen, Kari.
Plant-associated micro-organisms such as mycotoxin-producing endophytes commonly have direct negative effects on herbivores. These effects may be carried over to natural enemies of the herbivores, but this has been rarely explored. We examined how feeding on Neotyphodium endophyte infected (E+) and endophyte free (E−) meadow ryegrass (Scherodonus pratensis) affects body mass, population size and mobility of sibling voles (Microtus levis), and whether the diet mediates the vulnerability of voles to least weasel (Mustela nivalis nivalis) predation. Because least weasels are known to be olfactory hunters, we also examined whether they are able to distinguish olfactory cues of voles fed on E+ and E− diets. Neither body mass of voles nor population size...

Autores: Elmholt, S.; Labouriau, R.
A multi-soil study was conducted in Denmark including 29 sites, 8 classified as ‘Organic’, 11 as ‘Conventional with manure and synthetic fertilisers’ and 10 as ‘Conventional with synthetic fertilisers’. The variability of fungal abundance within the three farming systems and the long-term effects of different farming systems on fungal propagules in soil were evaluated.  Fungal abundance showed large variations within all three farming systems and this variability reduced the possibility to obtain general conclusions on fungal composition in soils under different farming systems. This was illustrated by the results on total propagule numbers of filamentous fungi and yeasts. Penicillium spp. and Gliocladium roseum were more abundant under organic than...

Fusarium Identification by PCR and DON Content in Grain of Ancient Wheat
Provedor de dados: 21
Autores: Konvalina, Petr; Capouchova, Ivana; Stehno, Zdenek; Moudry, Jan (Jr.); Moudry, Jan.
Fusarium infestation and DON content were studied in genetic resources of spring wheat (einkorn, emmer wheat, spelt wheat, intermediate forms of bread wheat). The study aimed at the comparison of grain contamination rates in various wheat species being grown in organic farming systems. The trials were established on certified organic parcels in two different localities in the Czech Republic in 2009 and 2010. The PCR method and specific primers were used to detect Fusarium. The proportion of deoxynivalenol (DON) was indicated and measured by the immuno-affinity chromatography (ROSA® DON Quantitative Test). The grain DON contamination rate (1.25 mg/kg) was set up in compliance with the European Commission (EC) Regulation No. 1126/2007. This regulation sets...

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.

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;...

Gastrointestinal metabolism of phytoestrogens in lactating dairy cows fed silages with different botanical composition
Provedor de dados: 21
Autores: Njåstad, Kari Marie; Adler, Steffen A.; Hansen-Møller, Jens; Thuen, Erling; Gustavsson, Anne-Maj; Steinshamn, Håvard.
Dietary phytoestrogens are metabolized or converted in the gastrointestinal tract of ruminants, only limited knowledge exists on the extent and location of this conversion in vivo. The objective of this study was to quantify the gastro-intestinal metabolism of phytoestrogens in lactating dairy cows fed silages with different botanical composition. Four lactating rumen cannulated Norwegian Red cattle were assigned to a 4?4 Latin square with 1 cow per treatment period of 3 wk. The 4 treatment silages were prepared from grasslands with different botanical compositions: organically managed short-term timothy (Phleum pratense L.) and red clover (Trifolium pratense L.) ley (2 yr old: ORG-SG); organically managed long-term grassland with a high proportion of...

Gene flow and population structure of a common agricultural wild species (Microtus agrestis) under different land management regimes
Provedor de dados: 21
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...

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...

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...

Generating Policy Capacity in Emerging Green Industries: The Development of Organic Farming in Denmark and Australia
Provedor de dados: 21
Autores: Daugbjerg, Carsten; Halpin, Darren.
In many cases, when governments commit themselves to green policy targets,they also imply the development of ‘green’ industries to reach those targets. But, how do governments foster the development of such industries? This is particularly relevant because such industries are often in a very early stage of their evolution. Taking the case of organic farming, we argue that the state’s ability to foster ‘policy capacity’ is critical to the emerging development trajectories of such industries. Focussing on the state’s ability to generate policy capacity in the Danish and Australian organic food sector,this article suggests that policy capacity develops as a result of high levels of state and associative capacity and the ability to create conditions favourable...

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...

Genetic analysis of predicted fatty acid profiles of milk from Danish Holstein and Danish Jersey cattle populations
Provedor de dados: 21
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...

Genetic compatibility determines endophyte-grass combinations
Provedor de dados: 21
Autores: Saikkonen, Kari; Wäli, Piippa R.; Helander, Marjo.
Even highly mutually beneficial microbial-plant interactions, such as mycorrhizal- and rhizobial-plant exchanges, involve selfishness, cheating and power-struggles between the partners, which depending on prevailing selective pressures, lead to a continuum of interactions from antagonistic to mutualistic. Using manipulated grass-endophyte combinations in a five year common garden experiment, we show that grass genotypes and genetic mismatches constrain genetic combinations between the vertically (via host seeds) transmitted endophytes and the out-crossing host, thereby reducing infections in established grass populations. Infections were lost in both grass tillers and seedlings in F1 and F2 generations, respectively. Experimental plants were collected as...

Genetic differences in root mass of Lolium perenne varieties under field conditions
Provedor de dados: 21
Autores: Deru, Joachim; Schilder, Henk; Schoot, Jan Rinze, van der; Eekeren, N. van.
Although grasses have dense rooting systems, nutrient uptake and productivity can be increased, and N-leaching reduced, if rooting is further improved. The variation in root mass of 16 varieties of Lolium perenne was studied under field conditions in two experiments on sandy soil in The Netherlands.The chosen varieties differed in genetic and aboveground characteristics such as ploidy, productivity and grass cover. Root dry matter (RDM) was measured in the 0–8, 8–16 and 16–24 cm soil layers. In summary, we found that RDM of perennial ryegrass differed significantly between arieties under field conditions. These differences were not linked to grass yield, which indicates that it is possible to select perennial ryegrass varieties that combine high...

Genetic Improvement of Livestock for Organic Farming Systems
Provedor de dados: 21
Autores: Boelling, Dorothe; Groen, Ab F.; Sørensen, Poul; Madsen, Per; Jensen, Just.
Over the last two decades, more and more farmers converted from  conventional to organic farming systems. The few breeds and genetic lines which are intensively used in conventional production systems are not necessarily well adapted to the conditions in organic farming, because  genotype * environment interactions may cause individual genotypes performing well in one environment to do poorly in another surrounding.   An example in poultry is given, illustrating that laying hens which were selected for high egg production in a cage, had a considerable decrease in number of eggs laid in a free-range system and furthermore developed unfavourable behaviour patterns like feather pecking. The range of phenotypes produced by one genotype can be determined by...

Genetic Improvement of Livestock for Organic Farming Systems

Autores: Boelling, D.; Groen, A.F.; Sørensen, P.; Madsen, P.; Jensen, J.
Organic farming which experienced a constant rise over the last two decades is a system based on sustainability and on a concept tending towards functional integrity. Legislation as well as the wish to produce separately from conventional farming raise the question whether organic farming should be conducted completely apart from conventional farming or not. This paper discusses the aspects that affect animal breeding under these circumstances, e.g., maintaining genetic diversity by using local breeds and possible G×E interactions which might occur when breeds adapted to conventional farming systems are used in organic farming. Ways of modelling G×E are presented, moreover examples of G×E in dairy cattle, swine, and poultry are given. Trends in selection...

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...

Genetic variation and pathogenicity of Phytophthora infestans isolates collected from organic potato crops of the susceptible cv. Bintje and the moderately resistant cv. Santé were assessed in France, Norway, and the United Kingdom in 2001 and in Switzerland in 2001 and 2002. Population structures differed considerably between the four P. infestans populations. Those from France, Switzerland and the UK were mainly clonal populations showing restricted levels of genetic diversity, whilst those from Norway were mixed A1 and A2 mating type populations with high levels of genetic diversity, suggesting periodical sexual reproduction. Isolates collected from cv. Bintje were on average more aggressive than or comparable to isolates from cv. Santé. Race complexity...

Genetic variation in specific root length in Scandinavian wheat and barley accessions
Provedor de dados: 21
Autores: Løes, Anne-Kristin; Gahoonia, Tara Singh.
Specific root length (SRL, m root g-1 root dry matter) was studied in a broad selection of old and presently grown accessions of spring wheat and barley from Norway and Sweden, at sub-optimal phosphorus conditions in nutrient solution and soil. The results indicated that genotype did not have a significant effect on SRL. A close relationship between root length (RL) and root weight (RW) was found, and more than 70% of the variation in root lengths was explained by root weights of representative and homogenous root samples. In nutrient solution, the relationship between RL and RW was described by the regression equations RL = 0.32RW – 0.19 (R2 = 0.74) for wheat and RL = 0.20RW + 0.73 (R2 = 0.56) for barley. In the soil experiment, the relationships between...

Genetically Modified Organisms (GMOs) as Invasive Species

This paper frames genetically modified organisms (GMOs) as invasive species. This offers a way of considering the reception, diffusion and management of GMOs in the foodscape. “An invasive non-native species is any non-native animal or plant that has the ability to spread causing damage to the environment, the economy, our health and the way we live” (NNSS, 2017). Without any social licence, pesticide companies have thrust GMOs into the foodscape. The release of GMOs has generally been unwelcome, there has been no ‘pull’ factor from consumers and there has been vocal resistance from many. The apologists for GMOs have argued the self-contradictory conceit that GMOs are ‘same but different’. Under this logically untenable stance, GMOs are to be excluded from...

Genotypic differences in growth, yield and nutrient accumulation of spring wheat cultivars in response to long-term soil fertility regimes
Provedor de dados: 21
Autores: Wang, Yaosheng; Magid, Jakob; Thorup-Kristensen, Kristian; Stoumann Jensen, Lars.
Determining genotypic responses to soil fertility may assist selection of cultivars that can be adapted to varied soil fertility regimes, and such selection under field conditions is still limited. A two-year field experiment was conducted in long-term field trials to investigate wheat genotype effects on early growth, yield and nutrient accumulation as affected by varied long-term soil fertility managements and nitrogen (N) fertilization. Results show that the early growth, grain yield and nutrient accumulation of spring wheat plants were strongly affected by soil fertility managements and genotypes. Early shoot and root biomass of singly grown plants and leaf canopy growth under standard growth density was associated with subsequent grain yield of plants...

Ocean Dumping  A German research vessel, the Polarstern, is on a 70 day exercise of dumping 20 tonnes of ferrous sulphate (iron sulphate, FeSO4) in the Southern Ocean at a latitude of 46° south. The LOHAFEX experiment of the Alfred Wegner Institute for Polar &amp; Marine Research project will increase the iron level of the treated ocean area by a factor of up to 24 times “the natural iron concentration”. The target area is 20 kilometres in diameter, i.e. approximately 320 square kilometres. It could be argued that the Southern Ocean being far away from sources of pollution,as well as international media, is an ideal place to conduct such a geo-engineering experiment, and that maybe this ocean fertilization experiment will be the seed for a whole new...

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...

Gesellschaftliche Leistungen des Ökolandbaus
Provedor de dados: 21
Autores: Stolze, Matthias.
Der Biolandbau erbringt mehr gesellschaftliche Leistungen als die konventionelle Landwirtschaft: So belasten Ökolandwirte beispielsweise die Umwelt deutlich weniger als ihre konventionell wirtschaftenden Kollegen. Sie schonen Ressourcen wie Boden, Luft und Wasser und schneiden auch beim Klimaschutz besser ab. Darüber hinaus fördern sie eindrücklich die Biodiversität. Wenn solche Leistungen künftig mit agrarpolitischen Maßnahmen honoriert werden sollen, hat der Ökolandbau die Nase vorn.

Gestalt, Geruch und Geschmack von Weizen im DOK-Versuch
Provedor de dados: 21
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...

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.

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...

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...

Glucosinolate profiling of seeds and sprouts of B. oleracea varieties used for food
Provedor de dados: 21
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....

GMOs and organic agriculture: Six lessons from Australia
Provedor de dados: 21
Autores: Paull, John.
GMO moratoria are in place in Australia, in some states and not in others. Is co-existence possible between organic farming and GMO farming? And if so, under what circumstances? Australia has more certified organic land than any other country, with a reported 12.0 million hectares of certified organic land compared to the world total of 37.5 million hectares. In a recent court case, an organic farmer lost his organic certification because of GMO contamination. A total of 325 hectares of his 478 hectare farm were contaminated with GM canola blown from a neighbouring property, and this resulted in the decertification of most of the farm. The organic farmer sued his neighbour, a GMO farmer, on the basis of nuisance or negligence, he sought damages for loss of...

Gode ideer til giftfri muse- og rottebekæmpelse
Provedor de dados: 21
Autores: Lodal, J.; Knorr, M.; Leirs, H.
I økologisk produktion er det stadig tilladt at anvende antikoagulanter til rottebekæmpelse. Kan brug af kemiske bekæmpelsesmidler i de økologiske bedrifter helt undgås, vil det være i god overensstemmelse med det grundlæggende koncept. Ved avl af frilandsgrise er der yderligere den faktor, at man er meget tættere på den frie natur, så ved brug af kemiske bekæmpelsesmidler har man en potentiel risiko for at påvirke og forgifte ikke-måldyr, altså de dyr der forekommer og ikke optræder som uønskede skadedyr. For at undgå problemer med mus og rotter er de forebyggende foranstaltninger en vigtig forudsætning, og disse skal overvejes både ved etablering og ved den daglige drift. Derved kan den egentlige bekæmpelse begrænses væsentligt.

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...

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...

Provedor de dados: 21
Autores: Ingvordsen, Cathrine Heinz; Gislum, René; Jørgensen, J.R.; Mikkelsen, Teis N; Jørgensen, R.B.
In the present study a set of 108 spring barley (H. vulgare L.) accessions were cultivated under predicted future levels of temperature and [CO2] as single factors and in combination (IPCC, AR5, RCP8.5). Across all genotypes, elevated [CO2] (700 ppm day/night) slightly decreased protein concentration by 5%, while elevated temperature (+5 °C day/night) substantially increased protein concentration by 29%. The combined treatment increased protein concentration across accessions by 8%. This was an increase less than predicted from strictly additive effects of the individual treatments.  Despite the increase in grain protein concentration, the decrease in grain yield at combined elevated temperature and elevated [CO2] resulted in 23% less harvestable protein....

Grain yield increase in cereal variety mixtures: A meta-analysis of field trials
Provedor de dados: 21
Autores: Kiær, Lars P.; Skovgaard, Ib; Østergård, Hanne.
Plant ecology theory predicts that growing seed mixtures of varieties (variety mixtures) may increase grain yields compared to the average of component varieties in pure stands. Published results from field trials of cereal variety mixtures demonstrate, however, both positive and negative effects on grain yield. To investigate the prevalence and preconditions for positive mixing effects, reported grain yields of variety mixtures and pure variety stands were obtained from previously published variety trials, converted into relative mixing effects and combined using meta-analysis. Furthermore, available information on varieties, mixtures and growing conditions was used as independent variables in a series of meta-regressions. Twenty-six published studies,...

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....

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...

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...

Green Food in China
Provedor de dados: 21
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...

Autores: Grüter, Roman; Costerousse, Benjamin; Bertoni, Angelina; Mayer, Jochen; Thonar, Cécile; Frossard, Emmanuel; Schulin, Rainer; Tandy, Susan.
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 use of green manure may contribute to reduce soil erosion and increase the soil organic matter content and N availability in coffee plantations in the Zona da Mata, State of Minas Gerais, in Southeastern Brazil. The potential of four legumes (A. pintoi, C. mucunoides, S. aterrimum and S. guianensis)to produce above-ground  biomass, accumulate nutrients and mineralize N was studied in two coffee plantations of subsistence farmers under different climate conditions. The biomass production of C. mucunoides was influenced by the shade of the coffee plantation.C. mucunoides tended to mineralize more N than the other legumes due to the low polyphenol content and polyphenol/N ratio. In the first year, the crop establishment of A. pintoi in the area took...

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)....

Greenhouse gas emissions from selected Austrian dairy production systems-model calculations considering the effects of land use change
Provedor de dados: 21
Autores: Hörtenhuber, Stefan; Lindenthal, Thomas; Amon, Barbara; Markurt, Theresia; Kirner, Leopold; Zollitsch, Werner.
The aim of this study was to analyze various Austrian dairy production systems (PS) concerning their greenhouse gas emissions (GHGE) in a life-cycle chain, including effects of land-use change (LUC). Models of eight PS that differ, on the one hand, in their regional location (alpine, uplands and lowlands) and, on the other hand, in their production method (conventional versus organic, including traditional and recently emerging pasture-based dairy farming) were designed.  In general, the GHGE-reducing effect of a higher milk yield per cow and year in conventional dairy farming cannot compensate for the advantages of organic dairy production which requires lower inputs. This is shown both for GHGE per kg of milk and GHGE per ha and year of farmland....

Greenhouse gas fluxes from agricultural soils under organic and non-organic management - A global meta-analysis
Provedor de dados: 21
Autores: Skinner, Colin; Gattinger, Andreas; Müller, Adrian; Mäder, Paul; Fließbach, Andreas; Stolze, Matthias; Ruser, Reiner; Niggli, Urs.
It is anticipated that organic farming systems provide benefits concerning soil conservation and climate protection. A literature search on measured soil-derived greenhouse gas (GHG) (nitrous oxide and methane) fluxes under organic and non-organic management from farming system comparisons was conducted and followed by a meta-analysis. Up to date only 19 studies based on field measurements could be retrieved. Based on 12 studies that cover annual measurements, it appeared with a high significance that area-scaled nitrous oxide emissions from organically managed soils are 492 ± 160 kg CO2 eq. ha− 1 a− 1 lower than from non-organically managed soils. For arable soils the difference amounts to 497 ± 162 kg CO2 eq. ha− 1 a− 1. However, yield-scaled nitrous...

Greening the Danes? Experience with consumption and environment policies.
Provedor de dados: 21
Autores: Christensen, T.H.; Godskesen, M.; Røpke, I.; Gram-Hansen, K.; Quitzau, M.-B.
Consumer-oriented environmental policies came high on the political agenda during the 1990s. Internationally, consumers were assigned a key role in environmental policies; also in Denmark, political initiatives were taken to promote sustainable consumer behaviour. In this article, the results of Danish policies related to consumption and environment are assessed by considering first, the environmental impacts of the political measures, and second, whether the policies have succeeded in addressing the dynamics behind increasing consumption. The study combines a theoretical understanding of consumption as an inseparable part of daily practices with empirical analyses of three fiels of consumption: housing, transportation and information and communication...

Grenzen und Möglichkeiten der ökologischen Rindfleischerzeugung in Mecklenburg-Vorpommern
Provedor de dados: 21
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.

Grønkål optager nitrat fra mere end 2 meters dybde
Provedor de dados: 21
Autores: Kristensen, Hanne L.; Thorup-Kristensen, Kristian.
Grønsager kan efterlade meget nitrat i jorden efter høst. Det skyldes at de fleste grønsager kræver en stor tilførsel af kvælstof for at udvikle sig godt, og samtidig er nogle grønsager dårlige til at udnytte det tilførte kvælstof. Hertil kommer at der ofte efterlades kvælstofrige planterester i marken ved høst. De omsættes hurtigt og mineraliseres til nitrat, der risikerer at blive udvasket og dermed forurene vandmiljøet. Både mijømæssigt og agronomisk er det uhensigtsmæssigt at tabe nitrat fra jordbrugssystemet. Det skulle hellere bruges til at give et godt udbytte af afgrøderne - ikke mindst i økologiske dyrkningssystemer.

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...

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...

Die EU Kommission hat im Juni 2010 entschieden, vorerst auf eine EU-weite Regelung für Biowein zu verzichten. Damit wurde eine grosse Chance verpasst für eine einheitliche und konsumentenfreundliche Regelung. Die Regelung hätte auch die Wettbewerbsfähigkeit europäischer Ökoweine gegenüber Konkurrenzprodukten aus Übersee verbessert. Was ist passiert, wie geht es nun weiter? Im EU-Forschungsprojekte ORWINE (2006-2009; www.orwine.org) hat ein europäisches Konsortium von sieben Forschungsinstituten und unter Einbezug von der Produktion, Handel und Konsumentinnen Grundlagen für die Erarbeitung von Kellerrichtlinien entwickelt.

Group composition for fattening entire male pigs underenriched housing conditions - Influences on behaviour,injuries and boar taint compounds
Provedor de dados: 21
Autores: Holinger, Mirjam; Früh, Barbara; Hillmann, Edna.
In organic farming, the production of pork from entire male pigs seems to be the mostpromising alternative to castration, as organic animal husbandry aims at high standards ofanimal welfare and elimination of mutilations. However, previous research on behaviourof entire male pigs was mostly carried out under barren housing conditions and is thus notentirely transferrable to enriched housing conditions. In the present study, we investigatedsingle-sex and mixed-sex groups of entire male pigs and compared them with mixed-sexgroups of castrated male pigs under organic housing conditions. On a commercial farm, 362pigs (average weight 22.7 kg, average age 80 days) were assigned to pens with groups of 20(+1) pigs according to three treatments: single-sex groups...

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.

Growing a local organic movement: The Mexican Network of Organic Markets
Provedor de dados: 21
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....

In the analyses of growing retail bargain power the organic vegetable chain in Denmark has been used as a case study focusing on two commodities: organic carrots and organic iceberg salads. These two were chosen to see if the differences in the length of durability between the two commodities would have an impact on the way contracts were made between producers and retailers/supermarkets.   Both commodities, however, were bargained on a similar basis which is covered by the main outline given in this paper.

GROWING OF THE ORGANIC POTATOES WITH USING OF THE MULCHING MATERIALS
Provedor de dados: 21
Autores: Dvorak, Petr; Tomasek, Jaroslav; Hamouz, Karel.
Mulching which has become more popular lately is an important way of soil protection in the plant production. Mulching massively reduces soil erosion [DÖRING ET AL., 2005], virus vector in seed potatoes [DÖRING ET AL., 2006] and it may also act as a tool for the control of nitrogen losses by immobilization of post-harvest nitrate [DÖRING ET AL., 2005].    Mulch especially reduces water evaporation from soil and helps to maintain stable soil temperature [JI AND UNGER, 2001; KAR AND KUMAR, 2007]. For that reason, the cover of mulch influences soil moisture as well [BRANT ET AL., 2006]. Next, mulching has a positive effect on the weed density, which has been documented by results of some authors [DÖRING ET AL., 2005; JOHNSON ET AL., 2004; SINKEVIČIENE ET AL.,...

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.

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.

Soil sickness is a widespread problem in replanted apple orchards with a complex symptomatology and etiology influenced by soil and climate conditions. Consequently, a conclusive technical solution is still lacking for intensive apple orchards. The present work aims to analyze the morphological and functional changes occurring in the M9 apple root systems growing in pot filled with soil derived from five different European growing areas. For each growing area, the soil was collected from the apple orchard and used directly in the pot or gamma-ray sterilized before potting. Soil from a neighborhood fallow was also used as control for each growing area. In the non-sterilized replant soils plants developed poor root systems due to a limited biomass...

Seit 2010 fallen in vielen europäischen Apfelanbaugebieten einzelne Bäume oder ganze Anlagen durch einen vorzeitigen Blattfall auf. Biologisch bewirtschaftete Apfelanlagen sind dabei häufiger von dieser Pilzkrankheit betroffen als integrierte. Im Rahmen einer Masterarbeit wurde versucht, dem Pilz auf die Spur zu kommen und die Grundsteine für die Resistenzzüchtung zu legen.

Gründüngungen richtig gewählt, mehr Stickstoff für die Hauptkultur
Provedor de dados: 21
Autores: Koller, Martin; Vieweger, Anja; Bauermeister, Regula; Total, René; Suter, Daniel; Mäder, Paul.
Gründüngungen sind wichtig zur Versorgung des Bodens mit Humus und Stickstoff. Sie vermindern das Auswaschen der Nährstoffe sowie die Oberflächenerosion und können das Unkrautwachstum unterdrücken. Die Biorichtlinien fordern neu, als Ersatz zum Bodenschutzindex, einen Mindestanteil Gründüngungen, der entweder ganzjährig oder über den Winter angebaut werden kann. Die Frage der Begrünungsmöglichkeiten nach Gemüseernten im Oktober ist für den Gemüseanbau besonders wichtig.

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...

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.

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...

Happy Growers! Relationship quality in the German organic apply chain
Provedor de dados: 21
Autores: Zander, Katrin; Beske, Philip.
Relational factors between supply chain actors have been acknowledged to contribute significantly to competitiveness. With the example of the German market for organic apples the suitability of the concept of the Relational View for explaining competitiveness was investigated. Structured interviews were conducted with selected actors of the supply chain. Actors at all levels of the supply chain proved to be highly committed and described their business relations as satisfying and trustful. Strong vertical and horizontal collaboration was found. Thus, the Relational View proved to be highly suitable to explain competitiveness in the market for organic apples.

Har holdningen til økologisk jordbrug konsekvenser for valget af forskningsmetoder?
Provedor de dados: 21
Autores: Borgen, Anders.
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.

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....

Hardy varieties in competition with weeds for sustainable agriculture and especially organic farming
Provedor de dados: 21
Autores: FONTAINE, L.; BERNICOT, M.-H.; ROLLAND, B.; POIRET, L.
A three-year programme was begun in 2007 to develop a method for assessing the competitive potential of wheat varieties with respect to weeds and to encourage the adoption of this criterion in selection programmes. The first year of experiments made it possible to identify the most explanatory characteristics of the competitive potential of wheat (using Italian ryegrass to simulate weeds): height first, followed by ground cover and leaf habit. These factors are nevertheless not adequate for totally predicting the competitive potential of wheat varieties and, in particular, intermediate varieties for which wide variations were observed from one situation to another in our experiments. We are now waiting for the results of two additional years of experiments.

Organic farming in Europe has increased rapidly since the early 1990s but still only accounts for a small share of production. This article analyses the structure and financial performance of organic farming in Europe using data from 18 countries. In the countries analysed, organic farms achieved significant price preniia for their outputs and were able to compete financially with conventional farms, with equal or higher profits in most cases, even though yields were up to 40 per cent lower. There was, however, a wide variation in performance within the samples and between countries and farm types. Consumer willingness to pay higher prices for organic products along with European Union and government support payments for organic farming and the design of...

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...

Autores: Bestman, Monique; Wagenaar, Jan-Paul.
From 2007–2008, data on animal health and welfare and farm management during rearing and laying periods were collected from 49 flocks of organic laying hens in the Netherlands. Our aim was to investigate how organic egg farms performed in terms of animal health and welfare and which farm factors affected this performance. The flocks in our study were kept on farms with 34 to 25,000 hens (average 9,300 hens). Seventy-one percent of the flocks consisted of ‘silver hybrids’: white hens that lay brown eggs. Fifty-five percent of the flocks were kept in floor-based housing and 45% of the flocks in aviaries. No relation was found between the amount of time spent outdoors during the laying period and mortality at 60 weeks. Flocks that used their outdoor run more...

Health biomarkers in a rat model after intake of organically grown carrots
Provedor de dados: 21
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,...

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...

Healthy food is nutritious, but organic food is healthy because it is pure: The negotiation of healthy food choices by Danish consumers of organic food.
Provedor de dados: 21
Autores: Ditlevsen, Kia; Lassen, Jesper; Sandøe, Peter.
There is increasing demand for organic food products throughout the Western world. Health concerns have frequently been found to be the main motivation of consumers purchasing organic products, but the literature on consumer preferences and behavior is less clear about what ‘health’ means to consumers of these products, and because of this it remains unclear what exactly drives consumers to choose organic products. This article investigates health from the perspective of consumers, and analyzes negotiations of, and justifications behind, their consumption preferences. The analysis is based on a focus group study conducted in Denmark in 2016. Three different understandings of health can be found when consumers explain their preferences for organic products:...

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...

Heart rate sensor validation and seasonal and diurnal variation of body  temperature and heart rate in domestic sheep
Provedor de dados: 21
Autores: Fuchs, Boris; Sørheim, Kristin; Chincarini, Mattheo; Brunberg, Emma; Stubsjøen, Solveig Marie; Bratsbergengen, Kjell; Hvasshovd, Svein Olaf; Zimmermann, Barbara; Lande, Unni Støbet; Grøva, Lise.
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...

Heat stress effects on farrowing rate in sows: Genetic parameter estimation using within-line and crossbred models
Provedor de dados: 21
Autores: Bloemhof, S.; Kause, A.; Knol, E.F.; Van Arendonk, J.A.M.; Misztal, I.
The pork supply chain values steady and undisturbed piglet production. Fertilization and maintaining gestation in warm and hot climates is a challenge that can be potentially improved by selection. The objective of this study was to estimate 1) genetic variation for farrowing rate of sows in 2 dam lines and their reciprocal cross; 2) genetic variation for farrowing rate heat tolerance, which can be defined as the random regression slope of farrowing rate against increasing temperature at day of insemination, and the genetic correlation between farrowing rate and heat tolerance; 3) genetic correlation between farrowing rate in purebreds and crossbreds; and 4) genetic correlation between heat tolerance in purebreds and crossbreds. The estimates were based on...

The aim of this study was to assess the prevalence of the major helminth infections affecting organic dairy cattle in northern Spain. Milk and faecal samples were obtained from 443 milking cows. Ostertagia ostertargi and Fasciola hepatica exposure was assessed by detection of specific antibodies in milk samples and F. hepatica infection was diagnosed by the detection of coproantigens in faecal samples. Dictyocaulus viviparus and Calicophoron daubneyi infections were diagnosed by conventional coprological techniques. The prevalence of infections caused by F. hepatica was considerable low, but similar to data reported from conventional farming in the same area. The prevalence rate of C. daubneyi infection was higher than previous data mirroring an increase...

Helminth parasites in pigs: New challenges in pig production and current research highlights
Provedor de dados: 21
Autores: Roepstorff, Allan; Mejer, Helena; Nejsum, Peter; Thamsborg, Stig Milan.
Helminths in pigs have generally received little attention from veterinary parasitologists, despite Ascaris suum, Trichuris suis, and Oesophagostomum sp. being common worldwide. The present paper presents challenges and current research highlights connected with these parasites.  In Danish swine herds, new indoor production systems may favour helminth transmission and growing knowledge on pasture survival and infectivity of A. suum and T. suis eggs indicates that they may constitute a serious threat to outdoor pig production. Furthermore, it is now evident that A. suum is zoonotic and the same may be true for T. suis. With these ‘new’ challenges and the economic impact of the infections, further research is warranted. Better understanding of host–parasite...

Hemp (Cannabis sativa L.) as a Resource for Green Cosmetics: Yield of Seeds and Fatty Acids Composition of 20 Varieties under the Growing Conditions of Organic Farming in Austria
Provedor de dados: 21
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...

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...

Herbicide impact on non-target plant reproduction: what are the toxicological and ecological implications?
Provedor de dados: 21
Autores: Boutin, Céline; Strandberg, Beate; Carpenter, David; Mathiassen, Solvejg Kopp; Thomas, P.J.
Declining plant diversity and abundance have been widely reported in agroecosystems of North America and Europe. Intensive use of herbicides within cropfields and the associated drift in adjacent habitats are partly responsible for this change. The objectives of this work were to quantify the phenological stages of non-target plants in in-situ field situations during herbicide spray and to compare plant susceptibility at different phenological stages. Results demonstrated that a large number of non-target plants had reached reproductive stages during herbicide spray events in woodlots and hedgerows, both in Canada and Denmark where vegetation varies considerably. In addition, delays in flowering and reduced seed production occurred widely on plants sprayed...

Herd characteristics influence farmers’ preferences for trait improvements in Danish Red and Danish Jersey cows
Provedor de dados: 21
Autores: Slagboom, Margot; Kargo, Morten; Edwards, David; Sørensen, Anders Christian; Thomasen, Jørn Rind; Hjortø, Line.
ABSTRACT  The aim of this study was to characterize preferences of farmers for breeding goal traits with Danish Red (DR) or Danish Jersey (DJ) cows. A breed-specific survey was established to characterize farmers’ preferences for improvements in 10 traits, by means of pairwise rankings using the online software 1000Minds. These pairwise rankings were based on equal economic worth of trait improvements. The DR survey was filled in by 87 farmers and the DJ survey by 76 farmers. Both DR and DJ farmers gave the highest preference to improvements in mastitis, and the lowest to calving difficulty. By means of a cluster analysis, three distinct clusters of farmers were identified per breed. Comparisons of herd characteristics between clusters suggest that farmers...

Herd health and health management in organic versus  conventional dairy herds in Norway
Provedor de dados: 21
Autores: Valle, Paul Steinar; Lien, Gudbrand; Flaten, Ola; Koesling, Matthias; Ebbesvik, Martha.
Earlier studies from Norway indicate that organic dairy farms enjoy better animal health than conventional dairy farms. However, these studies use veterinary treatment records and may not reflect the true health status since animal health may be handled differently, i.e. there might be different treatment schemes on organic versus in conventional farms. A study of animal health and health handling on both organic (n=149) and conventional (n=159) farms was performed based on information gathered from a mailed questionnaire merged with information from the Norwegian Cattle Health Services and the Norwegian Dairy Herd Recording System. Based on the original health records, there appeared to be many and large differences in herd health (veterinary) treatment...

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...

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...

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.

High damage potential of seed-borne spot blotch in organically grown spring barley in Denmark
Provedor de dados: 21
Autores: Pinnschmidt, Hans O.; Nielsen, Bent J.; Hansen, Henrik J.
Spot blotch of barley (Bipolaris sorokiniana, perfect state: Cochliobolus sativus) occurs wherever barley is grown but is normally not considered a major problem in Danish barley production. It is therefore not included in routine disease surveys or official variety testing in Denmark. However, recommended seed contamination thresholds are 30% for spring barley and 15% for winter barley. Several spring barley varieties were grown under organic (no seed dressing, mechanical weeding) and conventional (seed dressing with fungicides, herbicide application) production conditions at three sites in Denmark in 2003. The harvested seeds were analysed for contamination levels of seed-borne B. sorokiniana using a blotter method. The percentage of seeds contaminated...

High diversity of salmonella serotypes found in an experiment with outdoor pigs
Provedor de dados: 21
Autores: Jensen, A.N.; Lodal, J.; Baggesen,  D.L.
Little is known about the risk of Salmonella infection in outdoor pig production, but seroprevalence data has indicated a higher occurrence of Salmonella in outdoor production systems than in conventional indoor systems. This is perhaps due to the increased exposure to the surrounding environment including contact with wildlife. An unexpected high diversity of Salmonella serotypes, as e.g. S. Uganda and S. Goldcoast, which are not normally isolated from pigs, was detected in connection with an experimental study on transmission of Salmonella in outdoor organic pigs. In order to elucidate the potential source of the different Salmonella serotypes, a small-scale examination of wildlife was performed. Salmonella was not detected in any of a total of 22 rats,...

High Nitrogen Costs of Dairy Production in Europe: Worsened by Intensification
Provedor de dados: 21
Autores: Bleken, Marina Azzaroli; Steinshamn, Håvard; Hansen, Sissel.
Intensification of agriculture has been proposed as one way of minimizing emissions per unit of product, apparently legitimizing the ongoing structural changes in agriculture. We have investigated the relationship between the farming intensity and the nitrogen (N) dissipation by calculating the overall N emission factor (E: total N surplus per unit of N in the produce) from several studies of dairy farms, covering a wide range of environments and production intensities. Fundamental steps were 1) the distinction between trophic levels, mineral, plant and animal N; and 2) the inclusion of N losses related to bought feed. The results show that E increases significantly with the production intensity of the dairy farm. The tradition for separate optimization of...

Autores: Crichton, Stuart O.J.; Kirchner, Sascha M.; Porley, Victoria E.; Retz, Stefanie K.; von Gersdorff, Gardis J.E.; Hensel, Oliver; Sturm, Barbara.
Initial quality grading of meat is generally carried out using invasive and occasionally destructive sampling for the purposes of pH testing. Precise pH and thresholds exist to allow the classification of different statuses of meat, e.g. for detection of dry, firm, and dark (DFD) (when dealing with cattle and sheep), or pale, soft exudative meat (when dealing with pork). This paper illustrates that threshold detection for pH level in beef with different freshness levels (fresh, fresh frozen-thawed, matured, and matured frozen-thawed). Use of support vector machine (SVM) analysis allowed for the classification of beef samples with a pH above 5.9, and below 5.6, with an accuracy of 91% and 99% respectively. Biochemical and physical conditions of the meat...

High yield and low N leaching with barley as a green crop for silage after grass-clover
Provedor de dados: 21
Autores: Hansen, E.M.; Eriksen, J.; Vinther, F.P.
Danish organic farmers experience increasing difficulties with clover soil fatigue due to continuous cultivation of clover. A solution could be to undersow barley with Italian ryegrass after ploughing of grass-clover where the barley could be used as a green crop for silage (i.e., barley harvested at the beginning of heading), and Italian ryegrass could be used for cutting in autumn.   This method offers advantages not only for the farmer but also for the environment. When grass-clover is ploughed there is a high risk of N leaching. However, new field experiments show, that with the suggested method it is possible to reduce leaching to a minimum and simultaneously achieve a high production of roughage.

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...

Autores: Suja, Girija; Sundaresan, Sukumaran; Susan John, Kuzhivilayil; Sreekumar, Janardanan; Misra, Raj Sekhar.
Alternative agricultural systems, like organic farming, that are less chemical intensive, less exploitative and environment friendly are gaining popularity. Elephant foot yam (Amorphophallus paeoniifolius (Dennst.) Nicolson) is an important starchy tuberous vegetable with high nutritive and medicinal values. Since information on the organic farming of tuberous vegetables is scanty, field experiments were conducted in this crop at the Central Tuber Crops Research Institute, India, over a 5-year period. The impact of organic, conventional, traditional and biofertilizer production systems on growth, yield, quality, soil physico-Chemical properties and economics were evaluated in elephant foot yam. Our results show that organic farming favoured canopy growth,...

Autores: Dhamala, NR; Eriksen, J; Carlsson, G; Søegaard, K; Rasmussen, J.
Background and aims While N2-fixation in diversified grasslands including forage legumes and non-legumes has been widely studied, N2-fixation in swards containing only forage legumes remains unclear. In this study, we investigated N2-fixation in pure stands and mixtures of three forage legumes. Methodology N2-fixation, dry matter (DM) and nitrogen (N) yields were quantified in a field experiment for red clover (Trifolium pratense L.), white clover (Trifolium repens L.) and lucerne (Medicago sativa L.) pure stands and mixtures using the isotope dilution method. Results All three forage legume species derived most (around 85%) of their N from atmospheric N2-fixation (%Ndfa). However, no positive effect of species diversity was found in any of the mixtures....

Autores: Shatalina, Margarita; Messmer, Monika; Feuillet, Catherine; Mascher, Fabio; Paux, Etienne; Choulet, Frédéric; Wicker, Thomas; Keller, Beat.
Stagonospora nodorum glume blotch (SNG), caused by the necrotrophic fungus Stagonospora nodorum, is one of the economically important diseases of bread wheat (Triticum aestivum L.). Resistance to SNG is known to be quantitative and previous studies of a recombinant inbred line (RIL) population identified a major quantitative trait locus (QTL) for resistance to SNG on the short arm of chromosome 3B. To localize this QTL (QSng.sfr-3BS) with high resolution, we constructed a genetic map for the QTL target region using information from sequenced flow-sorted chromosomes 3B of the two parental cultivars ‘Arina’ and ‘Forno’, the physical map of chromosome 3B of cultivar ‘Chinese Spring’ and BAC-clone sequences. The mapping population of near-isogenic lines (NIL)...

High-resolution maps of Swiss apiaries and their applicability to study spatial distribution of bacterial honey bee brood diseases
Provedor de dados: 21
Autores: von Büren, Raphael S.; Oehen, Bernadette; Kuhn, Nikolaus J.; Erler, Silvio.
Honey bees directly affect and are influenced by their local environment, in terms of food sources, pollinator densities, pathogen and toxin exposure and climate. Currently, there is a lack of studies analyzing these data with Geographic Information Systems (GIS) to investigate spatial relationships with the environment. Particularly for intercolonial pathogen transmission, it is known that the likelihood of a healthy colony to become infested (e.g., Varroosis) or infected (e.g., American foulbrood-AFB, European foulbrood-EFB) increases with higher colony density. Whether these transmission paths can actually be asserted at apiary level is largely unknown. Here, we unraveled spatial distribution and high-resolution density of apiaries and bacterial honey...

High-temperature treatment for efficient drying of bread rye and reduction of fungal contaminants
Provedor de dados: 21
Autores: Kristensen, E.F.; Elmholt, S.; Thrane, U.
Mycotoxin producing fungi are natural contaminants of cereals and their toxins are harmful to humans and animals. Ochratoxin A (OTA) is among the most important. Heat treatment by drum drying does not eliminate already formed mycotoxins but the technique can reduce the number of viable fungi on the grain. The aim of this study was to establish a drying regime that kills fungal propagules on rye without reducing its quality for baking. Special attention was paid to some important mycotoxin producing species. As drying temperatures and retention time in the drum are essential, the drum drier must be equipped with an effective control unit. Two different control systems were tested. The results showed that fungi colonising the grain can be much more...

Histopathological study of the effect of post leaf fall application of urea on saprotrophic development of the cherry leaf spot pathogen, Blumeriella jaapii
Provedor de dados: 21
Autores: Bengtsson, M.; Hockenhull, J.; Neergaard, E.de.
The formation and development of over-wintering structures of the leaf spot pathogen Blumeriella jaapii in urea treated leaves of sour cherry (Prunus cerasus) during autumn, early winter and in May were studied histopathologically and compared to leaves treated with water. Resin embedding using glycol methacrylate (GMA) and subsequent staining of sections with Amido Black were used. Macroscopic and microscopic studies of B. jaapii in water treated leaves showed that the development of the over-wintering stages begins randomly in individual leaf spots both pre and early post leaf fall. Saprotrophic growth and stroma formation in leaves is completed between six to eight weeks after leaf fall. During the following spring stromata normally develop apothecia or...

Home range and dispersal of the field vole Microtus agrestis in an organic agro-ecosystem
Provedor de dados: 21
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...

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.

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.

Horse Welfare and Natural Values on Semi-natural and Extensive Pastures in Finland: Synergies and Trade-Offs
Provedor de dados: 21
Autores: Saastamoinen, Markku; Herzon, Irina; Särkijärvi, Susanna; Schreurs, Catherine; Myllymäki, Marianne.
In several regions in Europe, the horse is becoming a common grazer in semi-natural and cultivated grasslands, though the pasturing benefits for animals and biodiversity alike are not universally appreciated. The composition of ground vegetation on pastures determines the value of both the forage for grazing animals as well as the biodiversity values for species associated with the pastoral ecosystems. We studied three pastures, each representing one of the management types in Southern Finland (latitudes 60-61): semi-natural, permanent and cultivated grassland. All have been grazed exclusively by horses for several decades. Se aimed to evaluate feeding values and horses' welfare, on the one hand, and impacts of horses on biodiversity in boreal conditions,...

In future, conventionally produced seed will not be allowed for organic farming. Therefore, effective non-chemical methods are needed to control seed-borne diseases. Five important vegetable crops (carrot, cabbage, celery, parsley, lamb´s lettuce) and their most important seed-borne pathogens (Alternaria spp., Phoma spp., Septoria spp., Peronospora valerianellae, Xanthomonas spp.) have been investigated in laboratory, model and field trials.   Hot water treatments were made at temperatures of 40 °C and 50 to 55 °C for 10 to 30 minutes, in some cases to 60 minutes. In most cases, seed health tests were conducted according to ISTA guidelines. In case of seed infestation with Septoria species and P. valerianellae, the number of spores or oospores were counted...

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...

How are nematode communities affected during a conversion from conventional to organic farming in southern French vineyards?
Provedor de dados: 21
Autores: Coll, Patrice; Le Cadre, Edith; Villenave, Cécile.
The rate of conversion from conventional vineyards to organic farming practices is increasing. Organic farming improves some soil properties, although some organic practices have negative effects on soils. The objective of this work was to study the long-term effects of organic farming through the use of soil nematodes as bioindicators of soil processes. Our experimentation was conducted in a commercial vineyard where plots belonged to two types of viticulture: conventional viticulture and organic viticulture (for 7, 11 and 17 years). The nematode community structure and nematode indices were determined. The main result was that organic practices increased soil nematode density.

Biological N2 fixation (BNF), either asymbiotic, associative or symbiotic is considered a free and renewable resource, which should constitute an integral part of sustainable agro-ecosystems globally. Since the 1950ties and the invention of industrial synthesis of N-fertilizer there was a rapid increase in the use of fertilizer N worldwide and a parallel decline in the use of leguminous plants and BNF, especially in the developed world. Fertilizers have boosted crop yields, but the intensive agriculture often associated with heavy fertilizer use has resulted in increasing negative side effects on the atmospheric and aquatic environments. BNF, either alone or in combination with fertilizers and animal manures, may prove to be a better solution to nitrogen...

How Can Positional Concerns Prevent the Adoption of Socially Desirable Innovations?
Provedor de dados: 21
Autores: Salhi, Salima; Grolleau, Gilles; Mzoughi , Naoufel; Sutan, Angela.
We study the role of positional concerns in explaining the (non-) diffusion of profitable and environmentally friendly innovations in situations where there is no conventional prisoner dilemma. Based on anecdotal evidence from farming activities, we introduce the concept of negative positional goods, that is, goods that destroy status in a given reference group, and show how interactions between status concerns and profitability can lead to unexpected outcomes. Several policy implications are drawn.

How can veterinarians be interesting partners for organic dairy farmers? French farmers’ point of views
Provedor de dados: 21
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...

How do farming systems cope with marketing channel requirements in organic horticulture? The case of market-gardening in south-eastern France.
Provedor de dados: 21
Autores: Navarrete, Mireille.
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...

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...

How important is country-of-origin for organic food consumers? A review of the literature and suggestions for future research
Provedor de dados: 21
Autores: Thøgersen, John; Pedersen, Susanne; Paternoga, Maria; Schwendel, Eva; Aschemann-Witzel, Jessica.
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...

The interest of organic farmers in adopting conservation agriculture principles, including minimal soil disturbance, permanent soil cover and crop rotation has been growing since the early 2000s. However, currently there is no network for organic farmers practicing conservation agriculture, and a lack of knowledge on how organic farmers implement conservation agriculture in practice. Consequently, few technical references are available for organic farmers when they start applying conservation agriculture practices, in particular on controlling weeds without the use of herbicides. The main objectives of this study were: (1) to explore the diversity of conservation agriculture techniques (i.e., reduced tillage, no-tillage and green manures) practiced among...

How to construct a robust measure of social capital: Two contributions
Provedor de dados: 21
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...

How to fulfill EU requirements to feed organic laying hens 100% organic ingredients
Provedor de dados: 21
Autores: van Krimpen, M.M.; Leenstra, F.; Maurer, V.; Bestman, M.
From December 2017 onward, including non-organic protein sources in diets for organic poultry will no longer be allowed in the EU. Moreover, in the EU the use of synthetic amino acids in organic diets is prohibited. The main dietary challenge in European organic egg production is to fulfill the protein requirement, especially the methionine (Met) requirement of the hens. Currently available Met-rich ingredients are discussed. In the group of ingredients of plant origin, expelled sunflower seed has a relatively high digestible Met content and is also commonly available. Met content of plant ingredients can be increased by selection of high Met varieties and by specifically breeding on high Met content, e.g. by crossing different breeds. Plant processing...

How to improve consumers' environmental sustainability judgements of foods
Provedor de dados: 21
Autores: Lazzarini, Gianna A.; Visschers, Vivianne H. M.; Siegrist, Michael.
Food production and consumption account for approximately one-third of households' environmental impact. Consumers thus play a major role in the shift towards more sustainable foods and diets. An overall sustainability label or simple guidelines may enable consumers to make more environmentally friendly food choices, but whether such information-based tools improve consumers' ability to choose environmentally sustainable foods has not been empirically investigated. This study's online choice task experiment shows that eco-labels and guidelines marginally increased consumers' accuracy in selecting environmentally friendly foods. Respondents adhered, however, more to guidelines than to eco-labels and led to choices with lower environmental impact. In...

How to manage uncertainty in future Life Cycle Assessment (LCA) scenarios addressing the effect of climate change in crop production
Provedor de dados: 21
Autores: Niero, Monia; Ingvordsen, Cathrine Heinz; Jørgensen, Rikke B.; Hauschild, Michael Z.
When Life Cycle Assessment (LCA) is used to provide insights on how to pursue future food demand, it faces the challenge to describe scenarios of the future in which the environmental impacts occur. In the case of future crop production, the effects of climate change should be considered. In this context, the objectives of this paper are two-fold: (i) to recommend an approach to deal with uncertainty in scenario analysis for LCA of crop production in a changed climate, when the goal of  the study is to suggest strategies for adaptation of crop cultivation practices towards low environmental impacts, and (ii) to implement the suggested approach to spring barley cultivation in Denmark. First, the main implications of climate change for future crop...

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...

Humussphäre ist ein Projekt zu humusaufbauenden und energiesparenden Methoden in der Landwirtschaft. Durchgeführt wird es seit März 2005 auf dem Hof Hollergraben in Norddeutschland, einem 24 Hektar großen landwirtschaftliche Betrieb, der seit 1977 nach biologisch-dynamischen Richtlinien bewirtschaftet wird. Das Projekt Humussphäre untersucht zuerst Methoden, mit denen die Bodenfruchtbarkeit, die Bodengare und der Humusgehalt, also die Lebendigkeit des Bodens auf ein höheres Niveau angehoben werden kann, um dann festzustellen, ob auf diesen Böden Pferde wirtschaftlich und ökologisch erfolgreich eingesetzt werden können.  Im zweiten Jahr des Projektes (2006) wurden vorrangig betriebswirtschaftliche Aspekte des Zugpferde-Einsatzes behandelt.

Humussphäre ist ein Projekt zu humusaufbauenden und energiesparenden Methoden in der Landwirtschaft und versucht, Arbeitspferde in einem 24 ha großen Betrieb einzuführen.  Im vorliegenden Artikel über das Jahr 2007 wird vordergründig über Bodenverdichtungen, Heuernte, Zugkraftmessungen und die Ergebnisse einer Umfrage unter Fuhrleuten berichtet.  Die Bodenverdichtungen von landwirtschaftlich genutzten und vergleichbaren Flächen liegen im Traktorbereich um teilweise 80% höher als im Pferdebereich.   Das Reutern von Heu als Alternative zum Silagerundballen hat sich nicht bewährt.  Mittels einer Zugwaage können alle Arbeiten mit Zugpferden hinsichtlich des Zugkraftbedarfs ermittelt werden und die Geräte dann den Pferden bedarfsgerecht angepasst werden.

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.

Hybridizing money and moral: the case of Value Based Food Chains
Provedor de dados: 21
Autores: Laursen, Klaus Brønd.
Value Based Food Chains (VBFC) differ throughout Europe but are often found to share the same problem of integrating and maintaining their values as the chain grows. In this paper we analyse a number of VBFC that has succeeded in this manoeuvre. We argue that the success of these cases rely on the capability of the VBFC in question to combine both normative values and economic concerns equally, by allowing the two to become hybridised. The hybridisation, we argue, helps securing the reproduction of the central normative values without reducing them to an ‘added value’ to pass from one actor to another. Theoretically, we build our approach on social systems theory together with the theory of essentially contested concepts. Empirically, we draw on a number...

Autores: Wießner, S.; Thiel, B.; Krämer, J.; Köpke, U.
The hygienic quality of head lettuce (Lactuca sativa L.) was investigated after different fertilizer treatments (fresh farmyard manure, composted farmyard manure, stinging nettle extract and calcium ammonium nitrate) in a 2-year field experiment with two trials per year, respectively. For assessment of the hygienic quality the total aerobic bacterial counts, Enterobacteriaceae, coliform bacteria, Escherichia coli and Salmonella were investigated in soil, fertilizer and lettuce samples. Plants were washed with running tap water before analysis. The total aerobic bacterial count, as well as the levels of Enterobacteriaceae and coliform bacteria tended to be slightly higher (not significant) after organic compared to mineral fertilization. No Salmonella was...

Autores: Almeida-Funo, Izabel Cristina da Silva; Pinheiro, Claudio Urbano Bittencourt; Monteles, Josinete Sampaio.
Os tensores ambientais são definidos como qualquer fator que retire energia dos organismos e restrinja qualquer etapa de seu desenvolvimento causando um desequilíbrio no ambiente. Estes tensores, se bem definidos, podem ser utilizados no monitoramento de mudanças ecológicas e alterações hídricas constituindo-se um importante elemento na gestão dos recursos hídricos de uma região. A Baixada Maranhense, um complexo ecossistema alterado semestralmente pelo ciclo de chuvas, tem sido bastante alterado em função de elementos externos inseridos ao longo do tempo. Deste modo, o presente trabalho buscou por meio da etnoecologia identificar e descrever os principais tensores que atuam na região lacustre de Penalva. Os principais resultados obtidos demonstram que...

Identification of Distinct Functional Microstructural Domains  Controlling C Storage in Soil
Provedor de dados: 21
Autores: Steffens, Markus; Rogge, Derek M.; Mueller, Carsten W.; Höschen, Carmen; Lugmeier, Johann; Kölbl, Angelika; Kögel-Knabner, Ingrid.
The physical, chemical, and biological processes forming the backbone of important soil functions (e.g., carbon sequestration, nutrient and contaminant storage, and water transport) take place at reactive interfaces of soil particles and pores. The accessibility of these interfaces is determined by the spatial arrangement of the solid mineral and organic soil components, and the resulting pore system. Despite the development and application of novel imaging techniques operating at the micrometer and even nanometer scale, the microstructure of soils is still considered as a random arrangement of mineral and organic components. Using nanoscale secondary ion mass spectroscopy (NanoSIMS) and a novel digital image processing routine adapted from remote sensing...

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...

Identification of organically farmed Atlantic salmon by analysis of stable isotopes and fatty acids
Provedor de dados: 21
Autores: Molkentin, Joachim; Meisel, Hans; Lehmann, Ines; Rehbein, Hartmut.
Using isotope ratio mass spectrometry (IRMS), the ratios of carbon (δ13C) and nitrogen (δ15N) stable isotopes were investigated in raw fillets of differently grown Atlantic salmon (Salmo salar) in order to develop amethod for the identification of organically farmed salmon. IRMS allowed to distinguish organically farmed salmon (OS) from wild salmon (WS), with δ15N-values being higher in OS, but not from conventionally farmed salmon (CS). The gas chromatographic analysis of fatty acids differentiated WS from CS by stearic acid as well as WS from CS and OS by either linoleic acid or α-linolenic acid, but not OS from CS. The combined data were subjected to analysis using an artificial neural network (ANN). The ANN yielded several combinations of input data...

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...

Identifying factors that influence bird richness and  abundance on farms
Provedor de dados: 21
Autores: Zellweger-Fischer, Judith; Hoffmann, Jael; Korner-Nievergelt, Pius; Pfiffner, Lukas; Stoeckli, Sibylle; Birrer, Simon.
Capsule: Farmers can influence species richness and abundance of typical farmland birds positively, even on rather small farms (20–50 ha) within intensively farmed areas.  Aims: To assess the impact of farm settings, farm characteristics and heterogeneity of habitats on bird species richness and abundance, and to indicate which actions and measures farmers can take to promote farmland birds at a farm level.  Methods: Farmland bird species richness and abundance were modelled as a function of farm settings, farm characteristics and semi-natural habitats on 133 farms. The data were analysed at the farm scale, as this is the ‘operating range’ of a farmer, but also at the territory scale, which represents the range birds (mainly passerines) use during the...

The expansion of livestock production throughout the world has led to increased demand for high protein animal feed. This expansion has created economic benefits for livestock farmers and other actors in the chain, but also resulted in environmental and social side effects. This study aims to identify a set of sustainability issues that cover the environmental, economic and social dimensions of soymeal and beef production chains. The method applied combines the results of multiple studies, including a literature review and stakeholder surveys. Stakeholder surveys were conducted for three different interest groups (business, consumers, and other stakeholders) and two geographical regions (Latin America and the European Union). Our results reveal that the...

Identity as Constraint and Resource in Interest Group Evolution: A Case of Radical Organizational Change
Provedor de dados: 21
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...

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: 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. Il C.R.A.B. ha identificato sette cultivars locali di mais in Piemonte (Pignoletto giallo, Pignoletto rosso, Ostenga, Nostrano...

IL RUOLO DEL GENERE TRICHOGRAMMA NEL CONTENIMENTO DELLE INFESTAZIONI DI MAMESTRA BRASSICAE (L.) SU COLTIVAZIONI BIOLOGICHE DI CAVOLO IN PROVINCIA DI TORINO
Provedor de dados: 21
Autores: PINNA, MASSIMO; SPAGNOLO, SANDRA; GAMBA, URSULA.
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...

La fertirrigazione può essere utilizzata nei sistemi agricoli biologici dove,in sinergia con altre strategie di gestione della fertilità del terreno, può contribuire al raggiungimento di soddisfacenti risultati tecnici ed economici.  Tuttavia, per garantire i vantaggi agronomici ed ambientali propri delle produzioni organiche, la fertirrigazione non dovrebbe essere utilizzata come unica tecnica di fertilizzazione, semplicemente sostituendo ai concimi di sintesi i fertilizzanti organici consentiti in agricoltura biologica.

Ileal digestibility of sunflower meal, pea, rapeseed cake, and lupine in pigs
Provedor de dados: 21
Autores: Nørgaard, J.V.; Fernández, José A.; Jørgensen, Henry.
The standardized ileal digestibility (SID) of CP and AA was evaluated in soybean (Glycine max) meal, sunflower (Helianthus annuus) meal, rapeseed cake, and field pea (Pisum sativum) using 10 pigs and in lupine (Lupinus angustifolius) using 7 pigs. Pigs were fitted with either a T-cannula or a steered ileocecal valve-cannula. Diets contained 170 to 186 g CP/kg DM. Endogenous losses of CP and AA were estimated by feeding a N-free diet. The SID was calculated using the average of Cr2O3 and TiO2 as indigestible markers and corrected for type of cannula. The SID of CP was greater (P &lt; 0.05) for soybean meal and pea compared to sunflower meal, rapeseed cake, and lupine. The SID of Lys and His were lowest (P &lt; 0.05) in sunflower meal, and the SID of Met and...

Ileen Macpherson: Life and tragedy of a pioneer of biodynamic farming at Demeter Farm and a benefactor of Anthroposophy in Australia
Provedor de dados: 21
Autores: Paull, John.
Edith Ileen Macpherson (1898-1984) was a co-founder of Australia’s original biodynamic Demeter Farm (c.1934-1954) along with her partner Ernesto Genoni (1885-1974). Ileen was a member of Rudolf Steiner’s Experimental Circle of Anthroposophic Farmers and Gardeners (from 1936). Ernesto was the first Australian member (from 1928). At their Demeter Farm in Dandenong, Victoria, they practiced biodynamic agriculture on over 40 acres (16 ha) through the years of the Great Depression, through World War II, and for the first decade of the post-war years, producing milk, fruit, and vegetables. Ileen was an early Australian Anthroposophist and follower of Rudolf Steiner. It was a blow to their Demeter Farm enterprise when she fell ill. Eventually she was no longer...

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...

Impact dehulling oat grain to improve quality of on-farm produced feed. 2. Groat breakage and storability
Provedor de dados: 21
Autores: Peltonen-Sainio, Pirjo; Lehtinen, Pekka; Kontturi, Markku; Rajala, Ari; Kirkkari, Anna-Maija.
Dehulling improves markedly the feed value of oat (Avena sativa L.), but good storability of groat mass is required when large quantities of oat are dehulled at any one time. A laboratory model of an impact oat dehuller, similar to a commercial device, was used to study the effects of rotation speed and grain moisture content on groat breakage and the storage life of oat groats. Grain of oat cultivar Salo [from official variety trials, MTT Agrifood Research Finland, Jokioinen (60°49'N), 1996–2000] was dehulled with an impact oat dehuller using rotation speeds of 200 to 500 r min-1 at 50 r min-1 intervals. In an additional experiment, grains were moistened resulting in moisture content ranging from 10% to 18%. Proportion of broken groats and size...

The impact of a cultivar mixture within the rows including the cvs Melrouge (low susceptibility to scab) and Pitchounette (Rvi6 resistant) was assessed during 2008e2009 in an organic apple orchard located in Rhône Valley (Drôme, France), on three important pests and diseases: scab, powdery mildew and rosy apple aphid. In this area, the resistance of Rvi6 gene was effective since the orchard plantation in 2004. The impact of the cultivar mixture was assessed per se, but also associated with sanitation practices to decrease the primary inoculum of scab and mildew, and compared to disease development on pure stands of Melrouge. The cultivar mixture showed a good efficiency to decrease the scab incidence on leaves and fruits; a significant effect on scab...

Quantitative and qualitative analyses among the soil microarthropods can be used in biomonitoring as tools in multi-disciplinary approach to characterize soil quality. Three groups of microarthropods - Collembola and Oribatida as detrivores and Gamasina as predators - were selected to evaluate the impact of different management treatments adopted to recover degraded soil in organic. Differences in arthropod populations between French and Italian sites were registered. In Italy, after two years of recovering treatments, an increase of the abundances of all groups, particularly detritivores in degraded plots, was observed. The population of gamasids increased, in all sites, only in non degraded plots. Soil invertebrates of similar trophic groups, like...

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...

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...

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...

Provedor de dados: 21
Autores: Oehl, Fritz; Sieverding, Ewald; Ineichen, Kurt; Mäder, Paul; Boller, Thomas; Wiemken, Andres.
The impact of land use intensity on the diversity of arbuscular mycorrhizal fungi (AMF) was investigated at eight sites in the “three-country corner” of France, Germany, and Switzerland. Three sites were low-input, species-rich grasslands. Two sites represented low- to moderate-input farming with a 7-year crop rotation, and three sites represented high-input continuous maize monocropping. Representative soil samples were taken, and the AMF spores present were morphologically identified and counted. The same soil samples also served as inocula for “AMF trap cultures” with Plantago lanceolata, Trifolium pratense, and Lolium perenne. These trap cultures were established in pots in a greenhouse, and AMF root colonization and spore formation were monitored over...

Impact of large-scale organic conversion on food production and food security in two Indian states, Tamil Nadu and Madhya Pradesh
Provedor de dados: 21
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...

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....

Impact of low-input farming systems on earthworm populations in cereal crops - a paired farm approach in NW-Switzerland.
Provedor de dados: 21
Autores: Pfiffner, Lukas.
Effects of two different low-input farming systems on earthworms were compared. The study was performed in a 3-year field survey using a paired-farm approach in six different locations in northwestern Switzerland. Earthworms were extracted from soil sampled from 24 winter cereal crops and two herbaceous strips applying a combined method of extracting with a 0.33% mustard solution and a consecutive handsorting.  Differences of earthworm communities were found between and within the farming systems. In 14 of 24 cases, earthworms from organic fields were significantly richer in abundance and biomass than in the low-input integrated crop management farmed plots (ICM=no insecticides, fungicides and growth regulators); whereas the biomass resp. the abundance of...

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...

Impact of organic pig production systems on CO2 emission, C sequestration and nitrate pollution
Provedor de dados: 21
Autores: Halberg, Niels; Hermansen, John E.; Kristensen, Ib Sillebak; Eriksen, Jørgen; Tvedegaard, Niels; Petersen, Bjørn Molt.
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...

Impact of reduced tillage on greenhouse gas emissions and soil carbon stocks in an organic grass-clover ley - winter wheat cropping sequence
Provedor de dados: 21
Autores: Krauss, Maike; Ruser, Reiner; Müller, Tortsen; Hansen, Sissel; Mäder, Paul; Gattinger, Andreas.
Organic reduced tillage aims to combine the environmental benefits of organic farming and conservation tillage to increase sustainability and soil quality. In temperate climates, there is currently no knowledge about its impact on greenhouse gas emissions and only little information about soil organic carbon (SOC) stocks in these management systems. We therefore monitored nitrous oxide (N2O) and methane (CH4) fluxes besides SOC stocks for two years in a grass-clover ley – winter wheat – cover crop sequence. The monitoring was undertaken in an organically managed long-term tillage trial on a clay rich soil in Switzerland. Reduced tillage (RT) was compared with ploughing (conventional tillage, CT) in interaction with two fertilisation systems, cattle slurry...

Impact of reduced tillage on soil organic carbon and nutrient budgets under organic farming
Provedor de dados: 21
Autores: Gadermaier, Florian; Berner, Alfred; Fließbach, Andreas; Friedel, Jürgen Kurt; Mäder, Paul.
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.

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...

Impact of temperature and germination time on the success of a C4 weed in a C3 crop: Amaranthus retroflexus and spring barley
Provedor de dados: 21
Autores: Hyvönen, Terho.
Elevation in temperatures due to climate change could promote the invasion by C4 weed species of arable fields in the boreal region, which are dominated by C3 crops. The success of Amaranthus retroflexus L. (a C4 weed) in spring barley (a C3 crop) was studied at current and elevated temperatures (3°C difference) in a greenhouse experiment in southern Finland. The competition treatments included no competition and four levels of competition with barley, differing in terms of germination time. The success of A. retroflexus was measured as growth (height and biomass) and seed production (number and biomass). Elevation in temperature enhanced seed production of A. retroflexus, but the impact on growth was minor (only difference in plant height in one...

This study investigated the effect of, and interactions between, contrasting crossbreed genetics (US Brown Swiss [BS] x Improved Braunvieh [BV] x Original Braunvieh [OB]) and feeding regimes (especially grazing intake and pasture type) on milk fatty acid (FA) profiles. Concentrations of total polyunsaturated FAs, total omega-3 FAs and trans palmitoleic, vaccenic, a-linolenic, eicosapentaenoic and docosapentaenoic acids were higher in cows with a low proportion of BS genetics. Highest concentrations of the nutritionally desirable FAs, trans palmitoleic, vaccenic and eicosapentaenoic acids were found for cows with a low proportion of BS genetics (0–24% and/or 25–49%) on high grazing intake (75–100% of dry matter intake) diets. Multivariate analysis indicated...

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...

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...

Impact of wildflower strips on biological control of cabbage lepidopterans
Provedor de dados: 21
Autores: Pfiffner, Lukas; Luka, Henryk; Schlatter, Christian; Juen, Anita; Traugott, Michael.
In a 2-year experiment we investigated whether wildflower strips can be used to enhance the control of cabbage moth, Mamestra brassicae L., and cabbage white butterfly, Pieris rapae L. At two sites, including six organically cultivated fields, M. brassicae egg parasitism and predation rates were determined along with an assessment of larval parasitism rates in M. brassicae and P. rapae using a DNA-based approach. Within each field, plots with and without wildflower strips were sampled and a grid design of 3 m x   3 m was used to analyse the spatial pattern of parasitism. The provision of wildflower strips provided an idiosyncratic effect on the control of lepidopterans: parasitism rates in M. brassicae eggs and larvae were not affected, whereas parasitism...

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....

Increasing efficiency in livestock production and reducing the share of animal products in human consumption are two strategies to curb the adverse environmental impacts of the livestock sector. Here,we explore the roomfor sustainable livestock production by modelling the impacts and constraints of a third strategy in which livestock feed components that compete with direct human food crop production are reduced. Thus, in the outmost scenario, animals are fed only from grassland and by-products from food production. We show that this strategy could provide sufficient food (equal amounts of human-digestible energy and a similar protein/calorie ratio as in the reference scenario for 2050) and reduce environmental impacts comparedwith the reference scenario...

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...

Impediments to plant health in table grape production in southeastern France
Provedor de dados: 21
Autores: REYNAUD, C.
At the La Tapy Experimental Station in southeastern France, a plot of table grapes is managed according to the principles of organic farming in order to study potential technical impediments of this growing system compared to another plot that is managed according to the principles of sustainable agriculture. Muscat de Hambourg, the variety common to these two plots, is used as a reference for the different observations. Results are primarily related to the impact of pest management efficiency on vine quality. The qualitative requirement that powdery mildew be absent on table grapes is difficult to fulfil in the case of organic farming, even with several different treatments and frequent applications. Botrytis management is related to climatic conditions;...

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...

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...

Implications of organic management on yield, tuber quality and soil health in yams in the humid tropics
Provedor de dados: 21
Autores: Suja, G.; Sreekumar, J.
Global consciousness of food safety, health and environmental issues has stimulated interest in alternative agricultural systems like organic farming. Since information on organic farming of tuber crops is meagre, a field experiment was conducted in split plot design over a five-year period at Central Tuber Crops Research Institute, India. The aims were to evaluate the impact of organic, conventional and traditional production systems on yield, proximate composition and mineral content of tubers and soil physico-chemical and biological properties in three species of Dioscorea (white yam: D. rotundata, greater yam: D. alata and lesser yam: D. esculenta). The production systems were assigned to main plots and species to subplots. Organic farming (20.34 t...

Importance of Collection Overhangs on the Efficacy of Exclusion Fences for Managing Cabbage Flies (Diptera: Anthomyiidae)
Provedor de dados: 21
Autores: Bomford, Michael K.; Vernon, Robert S.; Päts, Peeter.
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...

Importance of cover crops in alleviating negative effects of reduced soil tillage and promoting soil fertility in a winter wheat cropping system
Provedor de dados: 21
Autores: Büchi, Lucie; Wendling, Marina; Amosse, Camille; Necpalova, Magdalena; Charles, Raphaël.
Reduction of soil tillage is of paramount importance for agricultural soil preservation. However, it is often accompanied by yield reduction and weed management problems. In this perspective, cover crops could play an important role to alleviate weed infestation and sustain yield. In this study, the results from a three-year experiment of cover crop cultivation in different soil tillage treatments is presented, together with results from DayCent simulations on the long term evolution of soil organic carbon and total nitrogen. Eight cover crop treatments were set up as subtreatments in a long term experiment in Switzerland. Cover crops were cultivated for a short two-month period between two winter wheats. Substantial differences in cover crop growth were...

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...

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...

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.

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...

Improving Crop Yield and Nutrient Use Efficiency via Biofertilization - A Global Meta-analysis
Provedor de dados: 21
Autores: Schütz, Lukas; Gattinger, Andreas; Meier, Matthias; Müller, Adrian; Boller, Thomas; Mäder, Paul; Mathimaran, Natarajan.
The application of microbial inoculants (biofertilizers) is a promising technology for future sustainable farming systems in view of rapidly decreasing phosphorus stocks and the need to more efficiently use available nitrogen (N). Various microbial taxa are currently used as biofertilizers, based on their capacity to access nutrients from fertilizers and soil stocks, to fix atmospheric nitrogen, to improve water uptake or to act as biocontrol agents. Despite the existence of a considerable knowledge on effects of specific taxa of biofertilizers, a comprehensive quantitative assessment of the performance of biofertilizers with different traits such as phosphorus solubilization and N fixation applied to various crops at a global scale is missing.

Improving the fatty acid profile of winter milk from housed cows with contrasting feeding regimes by oilseed supplementation
Provedor de dados: 21
Autores: Stergiadis, S.; Leifert, C.; Seal, C.J.; Eyre, M.D.; Steinshamm, H.; Butler, G.
Many studies show concentrations of nutritionally desirable fatty acids in bovine milk are lower when cows have no access to grazing, leading to seasonal fluctuations in milk quality if cows are housed for part of the year. This study investigated the potential to improve the fatty acid profiles of bovine milk by oilseed supplementation (rolled linseed and rapeseed) during a period of indoor feeding in both organic and conventional production systems. Both linseed and rapeseed increased the concentrations of total monounsaturated fatty acids, vaccenic acid, oleic acid and rumenic acid in milk, but decreased the concentration of the total and certain individual saturated fatty acids. Linseed resulted in greater changes than rapeseed, and also significantly...

In situ carbon and nitrogen dynamics in ryegrass-clover mixtures: Transfers, deposition and leaching
Provedor de dados: 21
Autores: Rasmussen, Jim; Eriksen, Jørgen; Jensen, Erik Steen; Esbensen, Kim H.; Høgh-Jensen, Henning.
Carbon (C) and nitrogen (N) dynamics in ryegrass-clover mixtures were investigated in field mezotrons installed to depths of 20, 40 and 60 cm and equipped with suction cups to collect percolating pore water. Ryegrass and clover leaves were cross-labelled with 14C- and 15N-enriched urea and the fate of the two tracers was studied for three months during summer. Transfer of 14C occurred mainly from ryegrass to clover, whereas the largest transfer of 15N was in the opposite direction. The average transfer of N from clover was 40% (±3.1, n=9) of N in ryegrass, whereas the fraction of N in clover donated by ryegrass was 5% (±1.2, n=9). The amount of 14C transferred from ryegrass to clover was 1.7% (±0.1, n=9) of the 14C-activity in the total aboveground biomass...

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...

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...

Incompatibility between fertility building measures and the  management of perennial weeds in organic cropping systems
Provedor de dados: 21
Autores: Melander, Bo; Rasmussen, Ilse A.; Olesen, Jørgen E.
Fertility building measures are important components in improving the productivity of organic cropping  systems without livestock. However, some measures seem to be incompatible with the control of  perennial weeds that can have adverse effects such as significant weed competition. The influence of  fertility building measures (N2-fixing crops in the crop sequence, cover crops and manuring) and the  abundance of perennial weeds were studied in a long-term crop rotation experiment at two locations in  Denmark. The aim was to gain insight into the factors that influence the growth of perennial weed species  occurring in mixed stands. Data were obtained from three cycles of four-year arable crop rotations  comprising various cash crops in rotations with and...

Incomplete split-plots in designs with many entries – a compromise between split-plots and randomized complete block designs
Provedor de dados: 21
Autores: Kristensen, Kristian.
The paper shows how the Alpha-design (also known as generalised lattice) may be used for constructing incomplete split-plot designs and describes 4 different methods (A, B, C and D) of construction. Intra-block efficiency factors and theoretical considerations are used to compare the methods. Based on those considerations method B was considered to be the most appropriate method for trials where tests for interaction between the two factors were important and thus this method was used and most of the paper deals with trials based on this construction method.     The incomplete split-plots were superior to traditional split-plots in most cases – and the increase in efficiency of the designs can be quite large – especially for comparisons involving the...

Incorporating Agroecology Into Organic Research - An Ongoing Challenge
Provedor de dados: 21
Autores: Niggli, Urs.
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...

Incorporation of Nitrogen-15-Labeled Amendments into Physically Separated Soil Organic Matter Fractions
Provedor de dados: 21
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...

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...

Increasing organic consumption by school meals – lessons learned in the iPOPY project
Provedor de dados: 21
Autores: Løes, Anne-Kristin; Nölting, Benjamin.
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)...

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...

Autores: Rasmussen, Ilse A.; Hansen, Preben Klarskov.
Kornafgrøder og –sorter har forskellig evne til at undertrykke ukrudt. Dette skyldes blandt andet sortens evne til at skygge for lyset og optage vand og næringsstoffer. For sorter med en samlet god konkurrenceevne gælder at:    de er langstråede   de har kraftig bladmasse gennem vækstsæsonen   de har en hurtig fremspiring og vækst    Denne viden er udnyttet til at beregne et konkurrenceindeks af sorten overfor ukrudt. De fleste forsøg vedrørende disse forskelle er gennemført under konventionelle forhold, hvor niveauet af næringsstoffer er højt, og ukrudt og andre skadevoldere bekæmpes kemisk.    Under økologiske forhold vil der oftest være en lavere og mere varierende forsyning med næringsstoffer. For at afklare om dette har en betydning for...

Autores: Panneerselvam, P.; Halberg, N.; Vaarst, M.; Hermansen, J.E.
In India, the number of farmers converting to organic farming has increased in the recent past despite the lack of government support in providing knowledge and extension to the farmers. The aim of this article is to investigate the perceived relevance, benefits and barriers to a conversion to organic agriculture in three different Indian contexts - in Tamil Nadu, Madhya Pradesh and Uttarakhand states. In each state, 40 farmers from both organic and conventional systems were interviewed. The findings indicated that conventional producers identified production and marketing barriers as the main constraints to adopting organic farming, while the age and education of the farmer were not deemed a problem. Lack of knowledge and lack of institutional support...

Induction of lactational estrus in organic piglet production
Provedor de dados: 21
Autores: Kongsted, A.G.; Hermansen, J.E.
The longer lactation period required in organic piglet producing herds reduces the potential number of produced litters per sow per year compared with that of conventional production. Induction and use of lactational estrus may be a way to increase the productivity in organic production. However, if lactational estrus is to be beneficial under practical husbandry conditions, it is crucial that the majority of sows are successfully mated within a few days to make batch farrowing procedures possible. The objective of this study was to investigate the occurrence and timing of lactational estrus in an organic outdoor system based on ad libitum feeding, individual housing until Day 35 in lactation, followed by grouping and introduction of a boar and weaning of...

Conclusions  The examination of the question, “why animals on farms” demonstrates the potential of “in-farm research” to gaining in-depth knowledge of the farm. The scientist’s observations and co-working on the farm are a method of choices that allows an accurate evaluation of the current situation of the farm, its atmosphere and the inner perspective of the farmers. It also lets the scientist contrast impressions from a personal point of view and to challenge statements made by the farmers. In addition, farmers were grateful for the “non-economic” assessments of the farm. As a consequence of this work, the reasons farmers give for keeping cows has become more conscious, and their decisions may strengthen their motives while also helping with public...

The effect of degraded soil conditions on microbial communities associating the rhizosphere and roots of grapevines was investigated within the frame of project CORE Organic Plus ReSolVe. Several relationships based on Dice cluster analyses of DGGE gel profiles suggest that fungal and bacterial communities from degraded and non-degraded areas differ. Results also suggest that composted organic amendments had an effect on community structures. However, the comparison of diversity indexes did not show differences between degraded and non-degraded plots. They suggested rich and even diversity of bacteria and fungi in any of the tested samples. Culture dependent analysis emphasized that a high diversity of Streptomyces spp. associates grapevine roots in...

Influence of a dry fractionation of butterfat on the content of fatty acids including conjugated linoleic acids
Provedor de dados: 21
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...

Provedor de dados: 21
Autores: Hilber, Isabel; Wyss, Gabriela S.; Mäder, Paul; Bucheli, Thomas D.; Meier, Isabel; Vogt, Lea; Schulin, Rainer.
Activated charcoal (AC) amendments have been suggested as a promising, cost-effective method to immobilize organic contaminants in soil. We performed pot experiments over two years with cucumber (Cucumis sativus L.) grown in agricultural soil with 0.07 mg kg_1 of weathered dieldrin and 0, 200, 400, and 800 mg AC per kg soil. Dieldrin fresh weight concentrations in cucumber fruits were significantly reduced from 0.012 to an average of 0.004 mg kg_1, and total uptake from 2 to 1 mg in the 800 mg kg_1 AC treatment compared to the untreated soil. The treatment effects differed considerably between the two years, due to different meteorological conditions. AC soil treatments did neither affect the availability of nutrients to the cucumber plants nor their yield...

Autores: Kohler, M.; Leiber, F.; Willems, H.; Merbold, L.; Liesegang, A.
This study investigated the influence of alpine grazing on vitamin D (vitD) and bone metabolism in sheep and goats. 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: Afrose, Sadia; Hammershøj, Marianne; Nørgaard, Jan Værum; Engberg, Ricarda M.; Steenfeldt, Sanna.
The aim of the study was to evaluate mussel meal and starfish meals as protein sources for organic layers by studying the effect on production performance, nutrient digestibility and egg quality. A total of 300 Hisex white laying hens (20-week old) were distributed randomly to 6 dietary treatment groups, each with five replicates, including a control diet providing fish meal, 3 diets providing mussel meal (4, 8 and 12 g/100 g) and 2 diets providing starfish meal (4 and 8 g/100 g). Laying rate, egg mass, feed conversion ratio, mortality and live weight of the hens did not differ among treatments. The egg weight was not different from the egg weights of control diets, but the inclusion of 4 g mussel meal resulted in a lower (P &lt; 0.05) egg weight than 8 g...

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.

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,...

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...

Influence of Different Plant Species on Methane Emissions from Soil in a Restored Swiss Wetland
Provedor de dados: 21
Autores: Bhullar, G.S.; Edwards, P.J.; Olde Venterink, H.
Plants are a major factor influencing methane emissions from wetlands, along with environmental parameters such as water table, temperature, pH, nutrients and soil carbon substrate. We conducted a field experiment to study how different plant species influence methane emissions from a wetland in Switzerland. The top 0.5 m of soil at this site had been removed five years earlier, leaving a substrate with very low methanogenic activity. We found a sixfold difference among plant species in their effect on methane emission rates: Molinia caerulea and Lysimachia vulgaris caused low emission rates, whereas Senecio paludosus, Carex flava, Juncus effusus and Typha latifolia caused relatively high rates. Centaurea jacea, Iris sibirica, and Carex davalliana caused...

Data collected in recent years has shown an enormous  growth in overall consumer health consciousness.  Nowadays the food industry is facing a new profile  of consumers, and these consumers are demanding  healthier options. Packaging claims are considered to  have an influence on consumer purchase decisions for  food products.  In our research we included 289 participants that answered  to our questionnaire that have two parts. The  first part of the questionnaire focuses on attributes  like: price (7 Romanian leu - RON, 12 RON; 1 EUR = 4.59  RON, exchange rate on 30.08.2017), origin (Romania,  European Union), drying method (microwave, sundried,  air-dried), and nutritional claim (with or without  nutritional claim) for a specific organic dried berries...

Influence of EU policy on agricultural nutrient losses and the state of receiving surface waters in Finland
Provedor de dados: 21
Autores: Ekholm, Petri; Granlund, Kirsti; Kauppila, Pirkko; Mitikka, Sari; Niemi, Jorma; Rankinen, Katri; Räike, Antti; Räsänen, Johanna.
In Finland, the first large-scale efforts to control nutrient loading from agriculture got under way with the introduction of the EU Agri-Environmental Program in 1995. We examined whether these efforts have decreased agricultural nutrient losses and improved the quality of receiving waters. To do so we used monitoring data on fluxes of nutrients and total suspended solids in agricultural catchments in 1990–2004 and on the water quality of agriculturally loaded rivers, lakes and estuaries in 1990–2005. No clear reduction in loading or improvement in water quality was detected. Hydrological fluctuations do not seem to have eclipsed the effects of the measures taken, since there was no systematic pattern in runoff in the period studied. The apparent...

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...

Among consumers in Europe and other parts of the world there is an increasing interest in high-value pork positioned with regard to animal welfare (Krystallis et al., 2012). Free-range pork production is considered more animal friendly because the system enables the animals to express their natural behaviour to a large degree. However, outdoor production of growing-finishing pigs on pastures as described by Halberg et al. (2010) has a major drawback in terms of high risk of nitrate leaching (Eriksen et al., 2006ab; Salomon et al., 2007). This is to a large extent related to high stocking densities combined with large input of nutrients from the supplementary feed (Eriksen et al., 2006ab). The use of supplementary feed is often higher in free-range compared...

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)....

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...

Autores: Schmidt, C. S.,; Agostini, F.,; Leifert, C.,; Killham, K.,; Mullins, C. E.,.
The effect of initial inoculum density of the antagonistic bacterial strains Pseudomonas fluorescens 135 and Pseudomonas corrugata 2140 (10(3) to 10(8) CFU per seed pellet) on sugar beet seedling colonisation, in situ bioluminescence and antagonistic activity towards Pythium ultimum was investigated. Populations of the bacteria colonising sugar beet root systems approached an apparent carrying capacity of 10(5) to 10(6) CFU per plant after 12 d growth, irrespective of inoculum density. This meant an up to 320-fold population increase at low inoculum densities and a decrease at high densities. Population densities of both bacteria and their corresponding in situ bioluminescence (resulting from luciferase enzyme expression from the inserted luxAB genes)...

Influence of liquid manure application method on weed control in spring cereals
Provedor de dados: 21
Autores: Rasmussen, K.
Injection of liquid manure (slurry)into the soil is an alternative to the traditional surface application. By the injection method,it is possible to place nutrients closer to the crop sown, thus offering the crop a competitive advantage over weeds. This study compares the response in crop yield, weed density and weed biomass to injection vs. surface application of liquid manure through three growing seasons in barley and oats. The manure applications were combined with treatments of weed harrowing or herbicide  spraying or no treatment at all. The levels of weed control and crop yield obtained by harrowing and herbicides were larger when slurry was injected compared with surface application. Without any weed control treatments,the injection method...

Influence of policy support on the development of organic farming in the European Union
Provedor de dados: 21
Autores: Padel, Susanne; Lampkin, Nic; Foster, Carolyn.
The paper explores the influence of policy support on the development of the organic sector. Policies include the agri-environment (EU Regulation 2078/92), the EU regulation 2092/91 defining organic crop-production in statutory terms and policies to support market and regional development and the information provision of organic farming. Policy makers have been interested in organic farming for its environmental and health benefits and the potential to contribute to the goals of regional development programmes. The evaluation suggests that the variation in support policies alone can not explain the different rates of conversion to organic farming in the EU.

Although reduced tillage is an agricultural practice reported to decrease soil erosion and external inputs while enhancing soil fertility it has still rarely been adopted by European organic farmers. The objective of this study was to assess the long-term interactive effects of tillage [conventional (CT) versus reduced (RT)] and fertilization [slurry (S) versus composted manure/slurry (MCS)] on earthworms and microbial communities in a clay soil under spelt in an organic 6-year crop rotation. Earthworm populations (species, density and biomass, cocoons) were investigated by handsorting the soil nine years after initial implementation of the treatments. Soil microbial carbon (Cmic) and nitrogen (Nmic) were measured by chloroform-fumigation extraction and a...

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...

Influence of storage of deep litter manure on ammonia loss and uniformity of mass and nutrient distribution following land spreading
Provedor de dados: 21
Autores: Hansen, Martin N.
Deep litter manure contains considerable amounts of plant nutrients and is therefore used as a fertiliser in crop production. However, the manurial value of deep litter manure is reduced by ammonia volatilisation and uneven land spreading. Although storage before spreading may improve the spreading evenness of deep litter manure, it may also influence the potential for ammonia losses. A study was therefore designed to investigate how storage of deep litter ma-nure influences spreading evenness and ammonia volatilisation following land spreading. The ammonia volatilisation following land spreading was found to be reduced by 44% following storage, as the ammonium content of the deep litter manure had declined considerably during the storage period.

The extraction of leaf proteins from perennial forage crops within a green biorefinery concept represents a promising approach to face the increasing demand for protein arisen in the organic farming sector to feed monogastric animals. Given the background, the present research aims at assessing the protein extractability from three plant species i.e. chicory, red clover and timothy, at different development stages and investigating lactic acid fermentation as the key method for the extraction of leaf proteins. Based on our results, up to 86% of the proteins in the green juice were recovered in the leaf protein concentrate (LPC) by means of lactic acid fermentation. Red clover presented the highest protein content and resulted in the extraction of 65e98 kg...

Provedor de dados: 21
Autores: Stracke, Berenike A.; Eitel, Joachim; Watzl, Bernhard; Mäder, Paul; Rüfer, Corinna E.
The present study was performed to evaluate the concentrations of phytochemicals (carotenoids and phenolic acids) in wheat varieties grown under comparable organic and conventional conditions over three years as part of a long-term field trial. Phenolic acids of the hydroxybenzoic acid and hydroxycinnamic acid group were quantified by HPLC-DAD after extraction as free, soluble conjugated, and bound forms. Furthermore, the carotenoids lutein and zeaxanthin were determined by HPLC-DAD. There were no statistically significant differences between the two farming systems (sum of carotenoids (microg/g) for 2003, 0.91 +/- 0.55 organic vs 0.96 +/- 0.34 conventional; for 2005, 1.61 +/- 0.22 organic vs 1.33 +/- 0.19 conventional; for 2006, 0.87 +/- 0.33 organic vs...

Influence on the ileal and fecal digestibility of forages inclusion in the diet
Provedor de dados: 21
Autores: Jørgensen, Henry; Carlson, D.; Lærke, H.N.
The present investigation aimed to study the ileal and fecal digestibility of three forages (Clover grass, Clover grass silage and Pea-Barley silage) supplemented to a basal diet. A total of 24 pigs, adapted to eating forages by supplementing a basal feed with clover grass silage from weaning, were fitted with a T-cannula at the terminal ileum at approximate 30 kg LW. For each of the three types of forage, two balance trials with 4 weeks interval were carried out. Two pigs in each test were fed the basal diet while 6 others were fed the basal diet plus forage throughout the whole experiment. The intake of forages was relative low and quite variable and accounted on average for only 10-12 % of the daily dry matter intake. Ileal digestibility estimated by...

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...

After reclamation of open-cast mining pits, soil formation starts from the deposited calcareous loess characterised by its basic physical and chemical properties whereas soil biology and structure need to develop to achieve a fully functional soil. In this study we used a chronosequence approach to elucidate soil formation on agriculturally reclaimed loess soils in an open-cast lignite mining area in Garzweiler (Germany). We selected six fields aged 0, 1, 3, 6, 12, and 24 years after the first seeding in order to observe the initial stage of development of soil properties and assess the role of management with conventional crop rotation in soil structure formation and soil organic carbon (SOC) accumulation. Loess parent material had a strong impact on...

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...

Innovating out of the Fishmeal Trap: The role of Insect-Based Fish Feed in Consumers’ Preferences for Fish Attributes
Provedor de dados: 21
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...

Autores: van der Weide, R.Y.; Bleeker, P.O.; Achten, V.T.J.M.; Plotz, L.A.; Fogelberg, F.; Melander, B.
Weed control within crop rows is one of the main problems in organic farming. For centuries, different weed removal tools have been used to reduce weeds in the crop rows. Stimulated by the demand from organic farmers, research in several European countries over the last decade has focused on mechanisation using harrowing, torsion finger weeding and weeding with compressed air (Pneumat). Intelligent weeders are now being developed which offer more advanced ways to control weeds, including larger ones and to leave the crop plants unharmed. One of the first commercially available intelligent weeders, the Sarl Radis from France, has a simple crop detection system based on light interception, which guides a hoe in and out of the crop row, around the crop...

Les résultats montrent tout d’abord que la filière de produits dits « biologiques » se structure en deux organisations de producteurs qui se différencient, tant par le mode de certification choisie que par leur niveaux d’insertion dans les dispositifs institutionnels conventionnels. Dans les deux cas néanmoins, un frein important est l’absence de maîtrise d’indicateurs sur les conditions d’évaluation économique et financière des produits biologiques. Par ailleurs, trois freins majeurs sont mis en évidence par l’analyse technico-économique et agronomique des exploitations (i) l’absence de référentiels et d’appui technique adaptés aux conditions locales, (ii) la faiblesse et la dispersion concernant l’approvisionnement et l’accès aux intrants adaptés et...

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...

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,...

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,...

Autores: Leiber, Florian; Gelencsér, Tobias; Stamer, Andreas; Amsler, Zivile; Wohlfahrt, Jens; Früh, Barbara; Maurer, Veronika.
Protein sources other than soybean for the diets of poultry are needed for agricultural systems in temperate regions to help avoid some negative social and ecological impacts of large-scale soybean imports from overseas. The aim of the present study was to test the suitability of alternative protein sources in diets for slow-growing organic broiler  chicken. Four experimental broiler diets were tested against a commercial feed for organic broiler chicken fattening (control), containing 255 g kg−1 soybean cake. Each experimental diet was based on the control diet, but 130 g kg−1 of soybean cake was replaced with alternative feeds. The diet ‘HermAlf’ contained 78 g kg−1 Hermetia meal (dried larvae of the black soldier fly, Hermetia illucens) and 52 g kg−1...

Insect growth regulator effects of azadirachtin and neem oil on survivorship, development and fecundity of Aphis glycines (Hemiptera: Aphididae) and its predator, Harmonia axyridis (Coleoptera: Coccinellidae)
Provedor de dados: 21
Autores: Kraiss, Heidi; Cullen, Eileen M.
BACKGROUND: Aphis glycines Matsumura, an invasive insect pest in North American soybeans, is fed upon by a key biological control agent, Harmonia axyridis Pallas. Although biological control is preferentially relied upon to suppress insect pests in organic agriculture, approved insecticides, such as neem, are periodically utilized to reduce damaging pest populations. The authors evaluated direct spray treatments of two neem formulations, azadirachtin and neem seed oil, under controlled conditions for effects on survivorship, development time and fecundity in A. glycines and H. axyridis.    RESULTS: Both azadirachtin and neem seed oil significantly increased aphid nymphal mortality (80 and 77% respectively) while significantly increasing development time of...

Insights to plant-microbe interactions provide opportunities to improve resistance breeding against root diseases in grain legumes
Provedor de dados: 21
Autores: Wille, Lukas; Messmer, Monika; Studer, Bruno; Hohmann, Pierre.
Root and foot diseases severely impede grain legume cultivation worldwide. Breeding lines with resistance against individual pathogens exist, but these resistances are often overcome by the interaction of multiple pathogens in field situations. Novel tools allow to decipher plant–microbiome interactions in unprecedented detail and provide insights into resistance mechanisms that consider both simultaneous attacks of various pathogens and the interplay with beneficial microbes. Although it has become clear that plant‐associated microbes play a key role in plant health, a systematic picture of how and to what extent plants can shape their own detrimental or beneficial microbiome remains to be drawn. There is increasing evidence for the existence of genetic...

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.

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...

Integrated Management of European Cherry Fruit Fly Rhagoletis cerasi (L.): Situation in Switzerland and Europe
Provedor de dados: 21
Autores: Daniel, Claudia; Grunder, Jörg.
Abstract: The European cherry fruit fly, Rhagoletis cerasi (L.) (Diptera: Tephritidae), is a highly destructive pest. The low tolerance for damaged fruit requires preventive insecticide treatments for a marketable crop. The phase-out of old insecticides threatens cherry production throughout the European Union (EU). Consequently, new management techniques and tools are needed. With the increasing number of dwarf tree orchards covered against rain to avoid fruit splitting, crop netting has become a viable, cost-effective method of cherry fruit fly control. Recently, a biocontrol method using the entomopathogenic fungus Beauveria bassiana has been developed for organic agriculture. However, for most situations, there is still a lack of efficient and...

Integrating indigenous knowledge of farmers for sustainable organic farming: An assessment in Uttarakhand state of India
Provedor de dados: 21
Autores: Bodapti, Subrahmanyeswari; Chander, Mahesh.
Success of organic farming largely depends on farmers’ knowledge of ecological systems, environment and on-farm renewable resources, as per the principles of organic farming. A study has been conducted to know the traditional knowledge and indigenous practices being followed by farmers in agriculture and animal husbandry to assess the possibility of integrating with organic farming in Uttarakhand, which is the first state in India promoting organic farming in a systematic way. The farmers of Uttarakhand especially women possessed a vast pool of indigenous knowledge with regards to livestock management leading to reduced dependence on externally purchased inputs as required under organic farming systems. And the farmers were in the practice of utilizing...

Integrating Physical and Cultural Methods of Weed Control – Examples from European Research
Provedor de dados: 21
Autores: Melander, Bo; Rasmussen, Ilse A.; Barberi, Paolo.
Increasing concerns about pesticide use and a steadily increasing conversion to organic farming have been major factors driving research in physical and cultural weed control methods in Europe.   This paper reviews some of the major results achieved with non-chemical methods and strategies especially adapted for row crops (e.g. corn, sugar beet, onion, leek, and carrot) and small grain cereals (e.g. barley and wheat). In row crops, intra-row weeds constitute a major challenge and research has mainly aimed at replacing laborious hand weeding with mechanization. A number of investigations have focussed on optimising the use of thermal and mechanical weeding methods against intra-row weeds, such as flaming, harrowing, brush weeding, hoeing, torsion weeding...

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...

Intensify pastures for livestock production: vermicompost use, an agro-ecological practice
Provedor de dados: 21
Autores: Boval, Maryline; Faverial, J.; Mulciba, P.; Loranger-Merciris, G.L.M.; Sierra , J.
The intensification of animal production at pasture is essential to meet the growing demand for animal products but also for other functions, the maintenance of areas, livelihoods and well-being of populations. This intensification must also take into account the reduction of agricultural land, promote positive interactions with the environment and biodiversity, while ensuring the supply of populations. The use of vermicompost involving the action of earthworms is an example of agro-ecological practices, to participate in the intensification of grassland and which has been studied in the context of a call to project, AGRIBIO3. Besides the fact that this practice makes it possible to achieve a proper recycling and recovery of various manures, it improves...

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...

Interactions between pre- and post-emergence weed harrowing in spring cereals
Provedor de dados: 21
Autores: Brandsæter, Lars O.; Mangerud, Kjell; Rasmussen, Jesper.
Pre- and post-emergence weed harrowing were studied in spring cereals in different environments and with two  types of harrows in Norway during 2004–2006. The objectives were to investigate interactions between pre and post-emergence weed harrowing and the importance of harrow type. We hypothesised that pre- and post-emergence harrowing interact positively, that a combination gives more stable weed control effects than pre- and post-emergence weed harrowing used alone, and that a harrow type with bent tines is more aggressive and suitable on hard-packed soils than a harrow with strait tines. The results only supported the last of these hypotheses. Post-emergence weed harrowing controlled a certain percentage of the present weeds, and this percentage was...

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...

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...

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.

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.

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).

Interspecific competition, N use and interference with weeds in pea-barley intercropping
Provedor de dados: 21
Autores: Hauggaard-Nielsen, Henrik; Ambus, Per; Jensen, Erik Steen.
Field pea (Pisum sativum L.) and spring barley (Hordeum vulgare L) were inter- and sole cropped to compare the effects of crop diversity on productivity and use of N sources on a soil with a high weed pressure. 15N enrichment techniques were used to determine the pea-barley-weed-N dynamics. The pea-barley intercrop yielded 4.6 t grain ha-1, which was significantly greater than the yields of pea and barley in sole cropping. Calculation of Land Equivalent Ratios showed that plant growth factors were used from 25 to 38% more efficiently by the intercrop than by the sole crops. Barley sole crops accumulated 65 kg soil N ha-1 in aboveground plant parts, which was similar to 73 kg soil N ha-1 in the pea-barley intercrop and significantly greater than 15 kg soil...

Provedor de dados: 21
Autores: Júnior, Edner Betioli; Moreira, Wagner Henrique; Tormena, Cássio Antônio; Ferreira, Camila Jorge Bernabé; Silva, Álvaro Pires da; Giarola, Neyde Fabíola Balarezo.
A qualidade física do solo é um dos fatores determinantes da sustentabilidade agronômica, econômica e ambiental no sistema plantio direto (SPD). A compactação do solo tem sido apontada como um dos fatores de redução da qualidade física em solos sob SPD. Contudo, com a utilização do SPD, pode haver o incremento de matéria orgânica do solo e o desenvolvimento de um sistema poroso contínuo e estável, que atenuam os impactos negativos da compactação. O objetivo deste trabalho foi avaliar a qualidade física de um Latossolo Vermelho distroférrico sob SPD durante 30 anos, utilizando o intervalo hídrico ótimo (IHO) e o grau de compactação do solo (GC). Em uma área comercial com histórico de altas produtividades sob SPD, foram coletadas amostras de solo com...

Introduction of Aureobasidium pullulans to the phyllosphere of organically grown strawberries with focus on its establishment and interactions with the resident microbiome
Provedor de dados: 21
Autores: Sylla, Justine; Alsanius, Beatrix. W.; Krüger, Erika; Reineke, Annette; Bischoff-Schaefer , Monika; Wohanka, Walter.
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....

Autores: Salovuo, Heidi; Ronkainen, Pilvi; Heino, Antti; Suokannas, Antti; Ryhänen, Eeva-Liisa.
When an automatic milking system (AMS) is introduced on a farm the milking of cows and related work is changed in many ways compared to farms with traditional milking systems. The objective of this paper was to study the effect of the introduction of robotic milking in Finland on the composition and hygienic quality of milk. The study was carried out on three farms which were the first in Finland to introduce the automatic milking system (Volontary Milking System™). Main chemical composition, somatic cell count, total bacteria count, freezing point, free fatty acids, as well as Bacillus cereus, Clostridium spores, psychrotrophic bacteria and coliforms were determined. After the introduction of the automatic milking system an increase in somatic cell count...

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...

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...

Provedor de dados: 21
Autores: Waldow, F.; Jahn, M.
The objectives of the present study were the determination of treatment threshold values for control of common bunt of wheat (Tilletia tritici) and evaluation of alternative seed treatments. Wheat seed inoculated with the fungus was sown in fields at three sites in Germany from 2002–2004. Seeds of three cultivars – ‘Naturastar’ (highly susceptible), ‘Aron’ (moderately susceptible), and ‘Batis’ (highly susceptible) – were first inoculated with 20, 100 and 1000 spores/seed and treated with Tillecur®, a natural plant strengthener, or hot water before planting. Untreated inoculated seeds were used as control. Bunt infection rates in the resulting wheat plants varied according to inoculum size, cultivar and treatment method, with additional variation between...

Investigations of organic food and health
Provedor de dados: 21
Autores: Brandt, Dr. Kirsten; Kristensen, Erik Steen.
Numerous studies have attempted to elucidate if there is a difference in  the effect on human health, between food produced according to the  organic standards compared with conventionally produced food. While  many studies support a few general trends of differences in food  composition, none have provided any conclusive evidence for differences  in the effects on human health. Most of the studies have been inadequate  in size or focus to allow any definitive conclusions. The major problem is  the complexity of the issue, and the general paucity of knowledge about  the impact of food on health, which means that it is virtually impossible  to tackle all relevant uncertainties in any one study. Instead a whole range  of different types of studies are needed...

In den vergangenen Jahren wurde die Methode der Ökobilanzierung weiterentwickelt und an die Bedürfnisse der Landwirtschaft angepasst. Mit vergleichenden Ökobilanzen wurden bereits bisher die Umweltauswirkungen der biologischen und integrierten Anbauweise erfasst. Diese Arbeiten beschränken sich jedoch auf die Ebene der Einzelkultur. Im vorliegenden Beitrag stellen wir vergleichende Ökobilanzen über eine ganze Fruchtfolgeperiode vor, die wir im Rahmen eines langjährigen Vergleichsversuches (DOK-Versuch) durchführten. Unter diesen Bedingungen schnitt das organisch- biologische Verfahren ökologisch besser ab als das konventionelle/integrierte.

Is an increase in organic consumption accompanied by a healthier diet? A comparison of changes in eating habits among Danish consumers
Provedor de dados: 21
Autores: Denver, Sigrid; Nordström, Jonas; Christensen, Tove.
Several studies have shown that consumers with a high organic consumption often have dietary habits that a more in line with the official recommendations of eating more fruit, vegetables, and less red meat. This paper takes a novel approach by  investigating whether changes in consumption patterns are also related: To what extent is an increase in organic consumption accompanied by improvements in dietary habits? We also investigate what motivates the consumers to change their habits and in what order the changes occur. Many consumers had relatively healthy dietary habits before the increase in purchases of organics. Mainly, households with originally high organic consumption seemed to improve their diet while increasing organic consumption. Reference to...

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...

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...

Is the enzymatic hydrolysis of soil organic phosphorus compounds limited by enzyme or substrate availability?
Provedor de dados: 21
Autores: Jarosch, K. A.; Kandeler, E.; Frossard, E.; Bünemann, E. K.
The mineralization of soil organic phosphorus (P) is catalysed by extracellular phosphatases that hydrolyse different non-phytate phosphomonoesters (e.g., sugar phosphates and nucleotides), inositol phosphates (e.g., phytic acids), and phosphodiesters (e.g., nucleic acids, phospholipids). The availabilities of both the organic P compound and the respective phosphatase enzyme jointly determine whether the hydrolysis reaction is substrate limited (enzyme availability &gt; substrate availability) or enzyme limited (enzyme availability &lt; substrate availability), with potential consequences for overall organic P composition and accumulation in soil. Our objective was to evaluate whether the hydrolysis of various organic P compounds in soil is limited by...

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...

Isolation and characterization of labile organic phosphorus pools in soils from the Askov long-term field experiments
Provedor de dados: 21
Autores: Guggenberger, Georg; Christensen, Bent T.; Rubæk, Gitte H.
Labile soil organic phosphorus (Po) plays a crucial role in plant P nutrition and in environmental eutrophication. This paper discusses recent studies on the nature of labile soil Po and its response to different fertilization practices. Soil material was obtained from the Askov long-term experiment on animal manure and mineral fertilizers. Our analytical approach combined a macroporous anion exchange resin to isolate labile Po and 31P NMR spectroscopy to assess the chemical composition and origin of NaOH-extractable Po. The analyses were carried out on fine earth (&lt;2 mm) and particle-size fractions. The results suggest that the resin extraction isolates an active pool of soil Po that consists primarily of microbially-derived compounds. The size of the...

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...

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...

Nebst der schonenden Verarbeitung spielt auch die Kartoffelqualität eine wesentliche Rolle. Besonders geeignete Posten kommen dieses Jahr neu als «Röstikartoffeln» auf den Markt.

Jordlivet under lupen – ulike modeller for å forstå plantenes næringsopptak
Provedor de dados: 21
Autores: Pommeresche, Reidun.
Jordlivet under lupen – ulike modeller for å forstå plantenes næringsopptak   Mikroorganismer er alfa og omega for fruktbar og god jord. De er jordas ryggrad, immunforsvar og fordøyelsessystem, og de lever i viktige samspill med røtter og andre jordorganismer. Et mer økologisk og biologisk fokus på prosesser i jord må vektlegges i forskning, rådgivning og praksis for å forvalte og bruke jordbruksjorda på en mer bærekraftig måte. For planteernæring er mer enn ionebytte og mineralisering av organisk materiale. I Möschberg i Sveits ble det i januar 2006 arrangert en konferanse som samlet 65 gardbrukerer, forskere og rådgivere med bakgrunn i biodynamisk, organisk-biologisk og økologisk landbruk fra Sveits, Tyskland, Østerrike og Norge. Temaet var...

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...

Kalium-Natrium-Verhältnis in Demeter-Möhren
Provedor de dados: 21
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.

Mange økologiske planteavlere har et stort ønske om at undlade pløjning. Pløjning har mange fordele men også ulemper. Et af formålene med RowCrop-projektet er at udvikle et system, hvor radrensning erstatter ploven. Erfaringer fra RowCrop-forsøget på Foulum viser, at førnævnte system kan lade sig gøre i praksis.

Kaolin clay, a new method for protecting plants against the peach aphid Myzus persicae Sulzer by creating a mineral barrier
Provedor de dados: 21
Autores: GARCIN, A.
The peach aphid Myzus persicae Sulzer is one of the major pests found on peach trees. The CTIFL has been running tests since 2005 to assess the efficacy of Surround® WP, a product containing kaolin that is applied either at the time of leaf fall to prevent winter egg-laying or in the spring to prevent the establishment of fundatrices. The period of application and the production system (organic or conventional) were tested, allowing a comparison with chemical aphicides. The clay product used at leaf fall reduced winter egg-laying by about 50%. Autumn application of Surround® alone was not sufficient to control aphid colonies in the spring, but it could be used as part of a supervised control strategy, combined with the application of mineral oils in late...

Karotten sind ergiebige Quellen an a- und ß-Carotin und weiterer sekundärer Pflanzenstoffe (SPS). Es ist bekannt, dass viele SPS auch für Geschmack, Aroma und Farbe eine Rolle spielen. Der Einfluss von Vorernte- und Nacherntefaktoren auf den Gehalt an SPS gewinnt deshalb zunehmend an Bedeutung. Für die Entwicklung eines Qualitätssicherungskonzepts sind die Kenntnisse über die Auswirkung dieser Faktoren unumgänglich.

Kein Super-GAU für Feldhasen - Naturschutz als Aufgabe einer multifunktionellen Landwirtschaft der Zukunft
Provedor de dados: 21

Dass sich "kontrolliert biologische" Landbewirtschaftung, die auf Pestizide und leichtlösliche Handelsdünger vezichtet, vielfältigere Fruchtfolgen und eine standortgebundene Tierhaltung ohne Futtermittelimporte aus Übersee anstrebt, auch auf die Natur positiv auswirkt, liegt auf der Hand. So zeigt sich auf ökologisch bewirtschafteten Ackerflächen nicht nur ein reicheres Bodenleben, sondern auch eine deutlich höhere Artenzahl der oft pauschal als "Unkraut" abqualifizierten Wildkräuter. Aber ein "Schwarz-Weiß-Denken" - die Umstellung auf Ökolandbau löst alle Naturschutzprobleme - ist Illusion. Einige Beispiele:

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...

Stigende fødevarepriser synes nu at bekræfte Browns logik. Men Kina producerer og eksporterer masser af mad, samtidig med at miljøproblemer plager land og by. Stigende miljøbevidsthed og urbanisering har også fremmet udviklingen af en ‘grøn’ produkt-standard og bidraget til, at Kina nu er en betydende spiller på verdensmarkedet for certificerede økologiske fødevarer.

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...

Klimarelevanz des Agrarsektors der Bundesrepublik Deutschland: Reduzierung der Emission von Kohlendioxid
Provedor de dados: 21
Autores: Haas, Guido; Geier, Uwe; Schulz, Dirk; Köpke, Ulrich.
Der Agrarsektor (Landwirtschaft, Garten- und Weinbau) der Bundesrepublik Deutschland (alt) verbrauchte im Jahre 1990/91 Energie in Höhe von ca. 413,82 PJ, entsprechend einem Anteil von näherungsweise 3,6% des nationalen Gesamtenergie-Einsatzes. Die daraus abgeleitete Kohlendioxid-Emission lag bei insgesamt ca. 27,658 Mio t CO2 und damit näherungsweise bei einem Anteil von insgesamt 3,9% der nationalen Emission. Flächenbezogen verursachte der Agrarsektor eine Kohlendioxid-Emission in Höhe von 2,344 t CO2 je Hektar.      Die von der Bundesregierung Deutschlands angestrebte CO2-Minderung von mittelfristig 25 - 30% kann auch innerhalb des Agrarsektors umgesetzt werden. Durch Optimierung der Produktion und den Einsatz von regenerativen Energien wird dieses Ziel...

Klimaschutz auf Kosten des Bodenschutzes?
Provedor de dados: 21
Autores: Beste, Andrea.
Die Nutzung von Bioenergie hat in den letzten Jahren aufgrund der weltweit wachsenden Energienachfrage und der Probleme des Klimawandels erheblich an Bedeutung zugenommen. Sowohl eine CO2-neutrale Energienutzung, als auch die Möglichkeit zur Einkommensdiversifizierung in der Landwirtschaft ist grundsätzlich zu begrüssen. Einseitige Fruchtfolgen und die Düngung mit C-reduzierten Gärresten führen jedoch zu weiterem Humusabbau. Gerade für den ökologischen Landbau ist die Verwendung von Biogasgülle in Bodenfruchtbarkeitshinsicht fraglich. Humusabbau verstärkt die Folgen des Klimawandels – Extremregenfälle, Hochwassergefahr und Dürre – wesentlich und ist angesichts der Auswirkungen auf die Erntesicherheit geradezu fahrlässig. Statt dessen müssten unsere...

Klimawandel: Anpassung des Betriebes - Größere Extreme verlangen mehr Flexibilität.
Provedor de dados: 21
Autores: Haas, Guido.
Klima und Witterung ändern sich: Es wird ganzjährig wärmer, im Winter nasser, im Sommer trockener, vor allem aber extremer, z. B. im Oberrheingraben, im Rheinland, in Ostdeutschland und Österreich. Rezepte zur Anpassung kann es daher keine geben. Auf den Klimawandel reagiert man am besten mit guter fachlicher Praxis des Ökolandbaus und Aufmerksamkeit unter zwei Prämissen: „Ertragsicherheit vor Maximalertrag“ sowie  „Vielfalt vor Spezialisierung“. Zu bedenken ist, dass kleinräumig hat der Ökolandbau den größten Flächenanteil mit geringer Standortgunst hat.  Doch gestalten Biobetriebe in der Regel vielfältige und damit stabilere Agrar-Ökosysteme. Die Nutzungsintensität  in Produktion und Landschaft ist geringer, die Biotop- und Artenvielfalt höher.

Kløvergræsmarker modvirker drivhuseffekten
Provedor de dados: 21
Autores: Carter, Mette S.; Amus, Per.
Lattergas (N2O) er en drivhusgas, som primært dannes når bakterier i jorden omsætter kvælstof. I Danmark anslås det, at landbrugets udledning af lattergas til atmosfæren udgør ca. 14 procent af det samlede udslip af drivhusgasser.  Ved beregning af udslippet af lattergas antages det at 1.25 procent af det kvælstof, der gødes med på marken, tabes som lattergas.     Dette gælder, når der er tale om gødning med handelsgødning.  Kløverplanter har den særlige egenskab, at de er i stand til at indbygge (fiksere) kvælstof fra luften, hvorved planterne kan medvirke til at ‘gøde’ sig selv og også gøde jorden for efterfølgende afgrøder. Kløvergræs (en blanding af græs og kløver) er derfor en vigtig afgrøde på både økologiske og konventionelle mælkebrug....

Knowledge and precaution. On organic farmers' assessment of new technology
Provedor de dados: 21
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...

Knowledge Asymmetries Between Research and Practice: A Social Systems Approach to Implementation Barriers in Organic Arable Farming
Provedor de dados: 21
Autores: Noe, Egon; Alrøe, Hugo Fjelsted; Thorsøe, Martin H.; Sørensen, Peter; Melander, Bo; Olesen, Jørgen E.; Fog, Erik.
Research in organic cropping systems has identified basic principles for increasing the robustness and production level of organic arable systems. But even though farmers know these principles, they have not implemented them in practice. This paper aims to improve our understanding of this “knowledge gap” using the theory of knowledge asymmetries, and discusses the implications for research, extension and practice. The paper is based on interviews with 10 organic arable farms focused on how to understand the barriers from the perspective and context of the farming system. The findings show that some barriers are due to lack of knowledge of suggested actions, calling for more ordinary dissemination. But this cannot at all explain all the barriers. The...

Knowledge transfer regarding the issue of animal health
Provedor de dados: 21
Autores: Hoischen-Taubner, Susanne; Bielecke, Alexandra; Sundrum, Albert.
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. Based on a socio-cognitive approach to knowledge transfer, different communication techniques (e.g. estimations of...

Koberwitz (Kobierzyce): In the footsteps of Rudolf Steiner
Provedor de dados: 21
Autores: Paull, John.
“Now once again we have made a great step forward!” exclaimed Rudolf Steiner on the drive back from Koberwitz. Koberwitz (now Kobierzyce, Poland) can fairly be regarded as the birthplace of biodynamic agriculture. Rudolf Steiner delivered eight lectures at the Koberwitz Chateau (Schloss Koberwitz) in German in the summer of 1924 (7-16 June). There were 111 attendees, 30 women and 81 men, who came from six countries: Germany, Poland, Austria, Switzerland, France, and Sweden. The audience included farmers, estate managers, doctors, priests, teachers, artists, and engineers who all came to hear Steiner’s vision for agriculture. A witness observed “Seldom have I seen him so joyfully moved after the completion of a task as in this moment after the agricultural...

Die aktuellen Schwierigkeiten im Agrarsektor haben ein bisher nicht dagewesenes Interesse an einer verstärkten Förderung des ökologischen Landbaus durch gezielte agrarpolitische Maßnahmen geweckt. Es werden Zielvorstellungen von bis zu 20% biologisch wirtschaftender Betriebe geäußert. Eine deutliche Zunahme dieser Betriebe ist aufgrund der weitgehend anerkannten und vielfach nachgewiesenen ökologischen Vorzüglichkeit der biologischen Landwirtschaft wünschenswert. Gleichzeitig stellt sich aber auch die Frage nach den ökonomischen und sozialen Konsequenzen einer weitgehenden Umstellung auf ökologischen Landbau.

Konstitution und arttypische Eigenschaften. Beurteilung der Konstitution von Milchkühen anhand der Ausprägung ihrer wesentlichen arttypischen Eigenschaften
Provedor de dados: 21
Autores: Spengler Neff, Anet.
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...

Körnerfrucht mit Solardach trocknen
Provedor de dados: 21
Autores: Haas, G.; Heipertz, C.; Schulze-Lammers, P.; Köpke, U.
Um Getreide und Körnerleguminosen ohne den Einsatz fossiler Energieträger trocknen zu können, wurde 1991 auf dem Versuchsbetrieb für Organischen Landbau Wiesengut/Hennef der Universität Bonn eine Solarkollektorenanlage zur Warmlufterzeugung errichtet. Die Anlage ist seit 8 Jahren im Einsatz und hat sich im Erntebetrieb bewährt. Der Energieeinspareffekt bezogen auf den Gesamtbetrieb ist allerdings vergleichsweise gering, da die Anlage nur wenige Tage im Jahr zum Einsatz kommen kann. Im Falle einer Kombination mit einer Unterdach-Warmluft-Heutrocknung wäre eine höhere Auslastung und Investitionsdeckung gegeben.   aus: Haas, G. Bioland 05/2000

Körnerleguminosen sollten aufgrund ihrer positiven Eigenschaften (N-Fixierung, Energie¬einsparung, Humusaufbau, Nährstoffmobilisierung) fester Bestandteil in Fruchtfolgen ökolo¬gisch wirtschaftender Betriebe sein. In der ökologischen Tierhaltung sind sie der wichtigste Eiweißträger in Futtermitteln.   Die gesamte Anbaufläche von Körnerleguminosen nimmt in Deutschland seit Jahren stark ab. Der Anteil der ökologisch angebauten Körnerleguminosen an der Gesamtfläche steigt dabei kontinuierlich an und beträgt bei Ackerbohnen und Lupinen inzwischen über 40 %. Doch auch im Ökologischen Landbau ist der Anteil der Körner¬leguminosen an der ökologisch bewirtschafteten Ackerfläche seit Jahren rückläufig. In 2008 betrug dieser nur noch 6,2 % der ökologisch...

Kornrensning mod meldrøjer
Provedor de dados: 21
Autores: Borgen, Anders.
Meldrøjer ses i rug som sorte kornlignende legemer på størrelse med kernerne. I virkeligheden er der tale om giftige sklerotierne af svampen Claviceps purpurea, som bestemt ikke hører hjemme i korn, hverken til foder eller menneskeføde.  Forekomst i økologisk korn  Meldrøjer er den eneste udsædsbårne svampesygdom på korn, som ikke har kunnet bekæmpes kemisk, heller ikke i konventionelt jordbrug. Rensning af såsæden har derfor altid været den primære foranstaltning til regulering af denne sygdom, så behandlingen adskiller sig ikke i økologisk og konventionelt jordbrug. De enkelte sklerotier kan have samme længde og bredde som rugkernerne. Derfor kan de ikke alle renses fra på et sold. Der er en lille forskel i vægtfylde og overfladestruktur mellem...

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.

Kubas Biolandbau-Revolution: Auskommen mit den eigenen Ressourcen
Provedor de dados: 21
Autores: Kilcher, Lukas.
Kreislaufwirtschaft, Einsatz betriebseigener Produktionsmittel und regionale Vermarktung sind zentrale Elemente des Biolandbaus. Auf den ersten Blick stehen diese im Widerspruch zu den riesigen Monokulturen Kubas und zu einer exportorientierten Landwirtschaft. Doch die Rückbesinnung auf eigene Ressourcen ist für Kuba eine Notwendigkeit. Der Biolandbau eröffnet den kubanischen Landwirtschaftsbetrieben zusätzliche Marktchancen und neue Wege, eine eigenständige Landwirtschaft umzusetzen.

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...

Kupfer als Pflanzenschutzmittel unter besonderer Berücksichtigung des Ökologischen Landbaus

Autores: Wilbois, Klaus-Peter; Kauer, Randolf; Fader, Beate; Kienzle, Jutta; Haug, Philipp; Fritzsche-Martin, Andreas; Drescher, Norbert; Reiners, Eckhard; Röhrig, Peter.
In den vergangenen 15 bis 20 Jahren hat der Öko-Landbau erhebliche Anstrengungen sowohl bei der Suche nach Kupferalternativen im Pflanzenschutz als auch bei der Minimierung der eingesetzten Kupfermengen unternommen. Allerdings sind bislang und in naher Zukunft keine Präparate oder Verfahren in Sicht, die einen annährend gleichwertigen Ersatz für Kupfer darstellen könnten. Dabei ist darauf hinzuweisen, dass ein gleichwertiger Ersatz nicht durch einen einzelnen Wirkstoff zu schaffen ist, wenn nicht ausgeschlossen werden kann, dass die betreffenden Schaderreger innerhalb kurzer Zeit Resistenzen gegenüber einem solchen Wirkstoff bilden. Unbenommen von allen Schwierigkeiten muss aber die Erforschung von Kupferersatzstoffen und -verfahren forciert werden.  In...

Kurzfristige und langfristige Auswirkungen von zwei Spritzfolgen im Kartoffelbau auf biologische Parameter der Bodenfruchtbarkeit
Provedor de dados: 21
Autores: Fliessbach, Andreas; Buchleither, S.; Peng, S.; Mäder, Paul.
Die Toxizität eines Pflanzenschutzmittels (PSM)wird anhand von Untersuchungen der Herstellerfirmen ermittelt und beruht in der Regel auf der Wirkung eines einzelnen Wirkstoffes oder Produktes auf einen definierten Indikator-Organismus. In der landwirtschaftlichen Praxis werden die Wirkstoffe jedoch häufig in Kombination mit anderen Mitteln oder in rascher Abfolge ausgebracht. Zu den kumulativen Wirkungen von Pestiziden, wie sie in einer Kultur angewendet werden, gibt es bislang nur vereinzelte Untersuchungen (Bromilov et al. 1996; Moorman, 1989; Nicholson und Hirsch, 1998; Schuster und Schröder, 1990).

Autores: Pugliese, Massimo; Gilardi, Giovanna; Gullino, Maria Lodovica; Garibaldi, Angelo.
Alcuni compost, addizionati al suolo o impiegati come componenti di substrati per colture in vaso, possono svolgere un’attività repressiva nei confronti dei patogeni terricoli. Nel biennio 2005-2006 sono stati saggiati, a Grugliasco (TO), in serre in ferro/vetro, compost provenienti da aziende di compostaggio presenti sul territorio piemontese al fine di valutarne la loro capacità repressiva. Dai risultati è emerso l’efficace contenimento nei confronti di F. oxysporum f.sp. basilici, da parte di compost prodotto a partire da rifiuti solidi urbani e fanghi, con una diminuzione fino al 50% di piante morte e un incremento fino al 25% di biomassa prodotta a fine ciclo rispetto a quanto rilevato impiegando un ammendante torboso scelto come riferimento.

Labile phosphorus forms in irrigated and rain-fed semiarid Mediterranean grassy crops with long-term organic and conventional farming practices.
Provedor de dados: 21
Autores: Romamyà, Joan; Rovira, Pere.
The availability of organic fertilisers plays a major role in organic farming systems. Such systems exclude the use of synthetic fertilisers, whilst  aiming to optimise internal nutrient cycling. The low availability of manures, particularly in dry areas, can lead to negative nutrient balances inmany  organic farming systems. Such negative nutrient balances are mainly found for P and K. In this paper,we aim to study the availability of P in irrigated  and rainfed semiarid Mediterranean grassy crops with long-term organic and conventional farming practices. NaHCO3 extracts were prepared from  an array of soils from 16 plots, covering organic and conventional management in rainfed and irrigated conditions.

Lack of increased availability of root-derived C may explain the low N2O emission from low N-urine patches
Provedor de dados: 21
Autores: Carter, Mette S.; Klumpp, Katja; Xavier, Le Roux.
Urine deposition on grassland causes significant N2O losses, which in some cases may result from increased denitrification stimulated by labile compounds released from scorched plant roots. Two 12-day experiments were conducted in 13C-labelled grassland monoliths to investigate the link between N2O production and carbon mineralization following application of low rates of urine-N. Measurements of N2O and CO2 emissions from the monoliths as well as δ13C signal of evolved CO2 were done on day -4, -1, 0, 1, 2, 4, 5, 6 and 7 after application of urine corresponding to 3.1 and 5.5 g N m-2 in the first and second experiment, respectively. The δ13C signal was also determined for soil organic matter, dissolved organic C and CO2 evolved by microbial respiration. In...

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).

Die Fleischqualität von Schlachtlämmern wird von einer Vielzahl von Faktoren bestimmt.  Neben dem Schlachtalter und dem Geschlecht hat v.a. die Fütterung einen grossen Einfluss auf die Fleischqualität. Grundsätzlich führt eine getreidelastige im Vergleich zu einer rauhfutterlastigen Fütterung zu den grössten Unterschieden in der Fleischqualität. Ein weiterer viel diskutierter Einfluss auf die Fleischqualität ist die Rasse. Beispielsweise wird ursprünglichen Rassen, wie z.B. der Heidschnucke, eine besonders hohe Fleischqualität nachgesagt, die sich auch in einem besonderen wildbretartigen Geschmack zeigen soll. Auch in der Schweiz  wird gewissen ursprünglichen Rassen eine speziell gute Fleischqualität zugesprochen.  Dieser Artikel befasst sich mit der...

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.

Land use alters the resistance and resilience of soil food webs to drought
Provedor de dados: 21
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...

Landbrug og landdistrikter før og nu
Provedor de dados: 21
Autores: Ingemann, Jan Holm.
Indtil for få årtier siden var landbrug den dominerende økonomiske, politiske og civilsamfundsmæssige kraft i danske landdistrikter. Med landbrugets strukturudvikling er dette billede radikalt ændrede, og landdistrikterne nu mere differentierede bl.a. afhængig af afstand til bymæssige vækstcentre. Landdistriktspolitik kan derfor ikke længere være sammenfaldende med landbrugspolitik.

Landraces and Obsolete Cultivars of Minor Wheat Species in the Czech Collection of Wheat Genetic Resources
Provedor de dados: 21
Autores: Stehno, Zdenek; Bradova, J.; Dotlacil, Ladislav; Konvalina, Petr.
Proportion of landraces in the Czech collection of wheat genetic resources differentiates deeply among wheat species, 4.2 % in bread, 77.6 % in emmer and 80.0 % in einkorn wheat collection. The set of 10 selected emmer wheat landraces has been characterised by high molecular weight glutenin subunits (HMW-GSs), evaluated for 3 years in field trials and described by grain quality parameters. Emmer wheat accessions distinguished considerably in polymorphisms of HMW-GSs. Out of the total number of 10 studied emmer wheat landraces 5 accessions appeared to be homogeneous in the electrophoretic patterns of HMW-GSs and they were formed by a single glutenin line. Much higher crude protein content in comparison with check bread wheat cultivar was detected in all...

Autores: Hansen, L.; Noe, E.; Højring, K.
Organic agriculture has potential for making a special contribution towards nature and landscape and the farmer plays an important part as decision maker. A qualitative interview study show that the farmer's production strategy often has an inpact on how he acts in relation to nature. At the same time it is difficult for the individual farmer to express concrete expectations of nature quality.

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.

Landschaftspflege mit Ziegen - Die Pflege von Magerrasen kann für Öko-Betriebe ökonomisch sein
Provedor de dados: 21
Autores: Rahmann, Gerold.
Aufgrund ihrer Futterselektion und dem breiten Futterartenspektrum eignen sich Ziegen für die Beweidung von Standorten auf denen Rinder, Pferde und Schafe kein ausreichendes Futter finden würden.  Es gibt allerdings nur wenige Erfahrungen in der Biotoppflege mit Ziegen, sodass es immer wieder zu Fehleinschätzungen und falschen Handlungen kommt.  Hier sollen einige Orientierungswerte zu den Themen Biotop-Arten, Weidemanagement, Tiergesundheit sowie zur Ökonomie angegeben werden, um eine betriebsindividuelle Planung und Umsetzung der Landschaftspflege mit Ziegen zu erleichtern und Fehler zu vermeiden. Ein Schwerpunkt bilden die besonderen Bedingungen bei der Beweidung von verbuschten, hängigen oder feuchten Flächen.

For the restoration of biodiversity in agricultural grasslands, it is essential to understand how management acts as an ecological filter on the resident species. Mowing constitutes such a filter: only species that possess functional traits enabling them to withstand its consequences can persist in the community. We investigated how the timing of mowing modulates this filtering effect for insects. We predicted that two traits drive species responses. Species with larval development within the meadow vegetation will suffer more from mowing than species whose larvae develop in or on the ground, or outside the meadows, while species with a later phenology should benefit from later mowing. We conducted a five‐year experiment, replicated at 12 sites across the...

Latent infection rate of potato seed tubers with Phytophthora infestans (Mont.) de Bary – an underestimated problem
Provedor de dados: 21
Autores: Zellner, Michael; Keil, Sven; Benker, Marianne.
From 2007 to 2009 applying molecular methods a total of 17 batches of seed potatoes were tested for the rates of latent infections with Phytophthora infestans (Mont.) de Bary, the pathogen of late blight. The samples were chosen randomly from different certified European seed potato productions. The average infection rate of the seed potatoes tested was 11%. The highest occurring rate was 38%. The given data show that there is no significant correlation between late blight susceptibility-levels of varieties and rates of latent infestation. There were no statistically significant differences found between seed potatoes from organic and conventional production.

Laying hen performance in different production systems; why do they differ and how to close the gap? Results of discussions with groups of farmers in The Netherlands, Switzerland and France, benchmarking and model calculations
Provedor de dados: 21
Autores: Leenstra, Ferry; Maurer, Veronika; Galea, Fabien; Bestman, Monique; Amsler-Kepalaite, Zivile; Visscher, Jeroen; Vermeij, Izak; van Krimpen, Marinus.
Free range and organic systems expose the laying hen more to unexpected events and adverse climatic conditions than barn and cage systems. In France, The Netherlands and Switzerland the requirements for a hen suitable to produce in free range and organic systems were discussed with farmers. The farmers preferred for these systems a more ‘robust’ hen, more specifically defined as a heavier hen with good eating capacity.  Benchmarking of flocks in a web-based management program in The Netherlands from layer flocks finished in 2008 – 2013 indicated that in earlier years indeed mortality among organic and to a lesser extent free range hens was higher than among barn or cage hens. Feed conversion (kg feed/kg eggs) is higher, but the gap is closing....

Increasing amounts of livestock manure are being applied to agricultural soil, but it is unknown to what extent this may be associated with contamination of aquatic recipients and groundwater if microorganisms are transported through the soil under natural weather conditions. The objective of this study was therefore to evaluate how injection and surface application of pig slurry on intact sandy clay loam soil cores influenced the leaching of Salmonella enterica serovar Typhimurium bacteriophage 28B, Escherichia coli, and Cryptosporidium parvum oocysts. All three microbial tracers were detected in the leachate on day 1, and the highest relative concentration was detected on the fourth day (0.1 pore volume).

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...

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.

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...

Learning and Innovation Networks for Sustainable Agriculture: Processes of Co-evolution, Joint Reflection and Facilitation
Provedor de dados: 21
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...

L'écologisation des pratiques en arboriculture et maraichage. Enjeux et perspectives de recherches
Provedor de dados: 21
Autores: Navarrete, Mireille; Bellon, Stéphane; Géniaux, Ghislain; Lamine, Claire; Penvern, Servane; Sautereau, Natacha; Tchamitchian, Marc.
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. Ces dernières années, la problématique de l'écologisation de l'agriculture, pour une meilleure préservation de l'environnement mais aussi de la santé des consommateurs, a particulièrement accru la pression sur le...

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...

Legehennen bevorzugen langsame Mauser
Provedor de dados: 21
Autores: Zeltner, Esther.
Legehennen werden zunehmend nur noch ein Jahr gehalten. Was sich wirtschaftlich lohnt, ist technisch und ethisch nicht unproblematisch. Bei längerer Nutzungsdauer erfolgt nach einem Legejahr die Mauser, wo sich das Tier regeneriert. Diese heikle Phase, die auch gezielt ausgelöst werden kann, hat das FiBL genauer unter die Lupe genommen.     Legehennen werden heute normalerweise mit zirka 20 Alterswochen vom Aufzuchtstall in den Legehennenstall umgestallt. Diese Umstellung bedeutet für die Hühner Stress. Im Legehennenstall bleiben die Hühner ein Jahr lang. Anschliessend werden sie geschlachtet. Mit 68 Alterswochen ist somit das Leben der meisten Hennen zu Ende.     Die kurze Nutzungsdauer ist aus technischen und ethischen Überlegungen nicht unproblematisch....

Legehennen werden heute normalerweise im Jahresumtrieb gehalten. Die Umstellung vom Aufzuchtstall in den Legehennenstall bedeutet für die Hühner eine Belastung, die umso grösser ist, je mehr sich das Aufzuchtsystem vom Legehennensystem unterscheidet. Mit 68 Alterswochen ist das Leben der meisten Hennen zu Ende. Die kurze Nutzungsdauer ist aus technischen und ethischen Überlegungen nicht unproblematisch. Die jährliche Eingewöhnungsphase der Hühner an den Stall ist für den Legehennenhalter immer mit dem Risiko verbunden, dass eine Herde in ihrer Anpassungsfähigkeit überfordert ist. Die Folge davon kann Federpicken oder sogar Kannibalismus sein.   Mit einer verlängerten Legedauer können die gut im Stall eingelebten Hennen länger genutzt werden und die Zahl...

Legumes are unique plants which contribute with several functions and services of great value for agriculture and society. Including legume food, forage and tree crops in farming systems is one approach to mitigate climate change. We have shown that the ability of the legumes to fix there own N via the symbiosis with rhizobia will reduce CO2 and N2O emissions compared to crops fertilized with industrial N. There is, however, a requirement to better understand the potential residual effects of legumes on N2O emissions. We have similarly shown that legumes have a key role in soilC sequestration and that the inclusion of legumes as sole crops, cover crops or intercrops usually enhances the rate of soil C accumulation even within relative short time periods....

Legumes in Finnish agriculture: history, present status and future prospects
Provedor de dados: 21
Autores: Stoddard, Frederick L.; Hovinen, Simo; Kontturi, Markku; Lindström, Kristina; Nykänen, Arja.
Legumes are important in world agriculture, providing biologically fixed nitrogen, breaking cereal disease cycles and contributing locally grown food and feed, including forage. Pea and faba bean were grown by early farmers in Finland, with remains dated to 500 BC. Landraces of pea and faba bean were gradually replaced by better adapted, higher quality materials for food use. While grain legumes have been restricted by their long growing seasons to the south of the country, red, white and alsike clovers are native throughout and have long been used in leys for grazing, hay and silage. Breeding programmes released many cultivars of these crops during the 1900s, particularly pea and red clover. A.I. Virtanen earned the 1945 Nobel Prize in Chemistry for his...

Leguminosenanbau richtig machen
Provedor de dados: 21
Autores: Loges, Ralf; Dreymann, Sonja; Wichmann, Stefan.
Durch die Fähigkeit Luftstickstoff (N2) biologisch binden zu können, stellen Leguminosen die wichtigste Stickstoffquelle im Ökologischen Landbau dar. Desweiteren liefern Leguminosen je nach Art und Nutzung große Mengen an Ernterückständen, die zur Humusbildung im Boden beitragen können.   Die Planung von Fruchtfolgen erfordert eine Möglichst genaue Abschätzung des Stickstoffeintrages durch Leguminosenanbau sowie der Verfügbarkeit dieses Stickstoffs für die Folgefrüchte.   Der Beitrag enthält eine Übersicht der Ergebnisse der in den letzten zehn Jahren an der Universität Kiel durchgeführten Feldversuche, die sich mit den  pflanzenbaulichen Steuermöglichkeiten der N2-Fixierung, der Ertragsleistung sowie der Lieferung von N bzw. organischer Masse in Form der...

Autores: Altherr, Wendy; Henryk, Luka; Nagel, Peter.
Leistus fulvibarbis Dejean, 1826, wurde zum ersten Mal seit mehr als 100 Jahren wieder für die Schweiz nachgewiesen. Anhand dieses Wiederfunds in Basel soll auf die Fundumstände eingegangen werden und die Verbreitung und mögliche Ausbreitungswege dieser Art diskutiert werden. L. fulvibarbis kommt von Westeuropa über den Mittelmeerraum bis nach Kleinasien vor (Horion, 1941; Turin, 1981) und wird bei Jeannel(1947) als typische Art für ein atlantisches Verbreitungsmuster vorgestellt. In Frankreich ist die Art verbreitet, fehlt aber im Nordosten (Jura und Vogesen) (Deville, 1921; Jeannel, 1941). Im Elsass ist sie bei Callot&amp; Schott (1993) nicht in der Faunenliste erwähnt, sondern nur als alte Meldungen ohne Belege von Bourgeois (ca. 1910) und Scherdlin...

Cet article présente les pratiques et attitudes des responsables de magasins spécialisés envers l’approvisionnement local de leurs produits. Presque deux tiers de ces magasins y ont recours (en majorité des grands magasins), avec des appréciations mitigées : si des avantages évidents, comme la fraîcheur des produits régionaux, sont notés, les distributeurs regrettent un manque de professionnalisme et d’engagement de la part des fournisseurs agricoles. Les consommateurs sont quant à eux très sensibles à l’origine régionale des produits biologiques, plus parce qu’elle est synonyme d’accès direct et de transparence qu’en raison de préoccupations environnementales (« food miles » ou kilomètres alimentaires). Les résultats obtenus nous permettent de proposer...

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...

Autores: Bosona, Techane; Gebresenbet, Girma.
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...

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...

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...

Limitation des populations de ravageurs de l’olivier par le recours à la lutte biologique par conservation
Provedor de dados: 21
Autores: WARLOP, FRANCOIS.
L’olivier est une culture relativement rustique, mais qui peut être fortement attaquée par la mouche Bactrocera oleae (Gmelin), son principal ravageur. Les parasitoïdes de cette mouche sont connus, mais leur impact sur les populations de Diptères demeure faible, faute d’aménagement adéquat du paysage et suite à une intensification abusive des pratiques culturales. Le programme d’installation de bandes florales mené par le Groupe de recherches en agriculture biologique qui a débuté en 2004 vise à rétablir des relations tritrophiques, entre la faune auxiliaire, les espèces d’insectes nuisibles et les plantes adventices, en favorisant l’installation de ces dernières. L’Organisation internationale de lutte biologique et intégrée (OILB) considère que la lutte...

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...

Linking Soil Microbial Activity to Water- and Air-Phase Contents and Diffusivities
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,...

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...

Links between profitability, nitrogen surplus, greenhouse gas emissions, and energy intensity on organic and conventional dairy farms
Provedor de dados: 21
Autores: Flaten, Ola; Koesling, Matthias; Hansen, Sissel; Veidal, Asbjørn.
This study examines the relationships between profitability,nitrogen (N) surplus, greenhouse gas emissions (GHG), and energy intensity and factors influencing these relationships in dairy farming. In-depth data from 10 conventional and 8 organic dairy farms in Western Norway were analyzed. Organic farms had lower N surplus per hectare (local, onfarm) and per unit output (global, cradle-to-farm-gate), and lower estimated GHG emissions and energy intensity per unit output, whereas labor input and farm profits did not differ. Higher profitability tended to be associated with improved performance of the environmental indicators examined.  Intensification through increased use of concentrates tended to improve profit and reduce N surplus, GHG emissions, and...

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.

Local knowledge held by farmers in Eastern Tyrol (Austria) about the use of plants to maintain and improve animal health and welfare
Provedor de dados: 21
Autores: Vogl, Christian R.; Vogl-Lukasser, Brigitte; Walkenhorst, Michael.
Background    The sustainable management of animal health and welfare is of increasing importance to consumers and a key topic in the organic farming movement. Few systematic studies have been undertaken investigating farmers’ local knowledge related to this issue. Ethnoveterinary medicine (EVM) is a discipline focusing on local knowledge and folk methods in veterinary medicine, however most ethnoveterinarian studies primarily address the treatment of animal diseases. Very few studies have explored prophylactic methods.  Methods  An ethnoveterinary research project in Eastern Tyrol (Austria) was conducted in 2004 and 2005 to gather information about local knowledge of animal husbandry from 144 informants, with the emphasis on plants that maintain livestock...

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.

Localisation of primary food production in Finland: production potential and environmental impacts of food consumption patterns
Provedor de dados: 21
Autores: Risku-Norja, Helmi; Hietala, Reija; Virtanen, Hanna; Ketomäki, Hanna; Helenius, Juha.
The potential for and environmental consequences of localising primary production of food were investigated by considering different food consumption patterns, based on conventional and organic production. Environmental impact was assessed according to agricultural land use and numbers of production animals, both of which depend on food consumption. The results were quantified in terms of nutrient balances, greenhouse gas and acid emissions and the diversity of crop cultivation, which indicate eutrophication of watersheds, climate change and landscape changes, respectively.    The study region was able to satisfy its own needs for all farming and food consumption scenarios. Dietary choice had a marked impact on agricultural land use and on the...

Localized application of sewage sludge improved plant nitrogen and phosphorus uptake by rhizobox-grown spring wheat
Provedor de dados: 21
Autores: Wang, Yaosheng; Stoumann Jensen, Lars; Magid, Jakob.
Sewage sludge (SS) can be used as an alternative fertilizer in agriculture. It is normally broad- casted and plowed into soil, but it is not clear if it has a potential as a placement fertilizer. A rhizo- box experiment was conducted to investigate the placement effect of SS and mineral nitrogen (N) fertilizer on shoot and root growth as well as nutrient uptake of spring wheat (Triticum aesti- vum L.). The treatments included localized SS, mixed SS, localized SS and ammonium, local- ized ammonium, and a control without addition of SS and ammonium to examine the effect of SS placement and, further, if ammonium co-localization would enhance the placement effect. The re- sults show that SS fertilization improved soil N and P availability, which significantly...

Localized organic agri-food supply chains in Rhône-Alpes (France): diversity of organisations and highlights of the notion of proximity
Provedor de dados: 21
Autores: Chazoule, Carole; Fleury, Philippe; Vitrolles, D.
For ten years, innovative forms of distribution of organic products have emerged between long and short supply chains. They are often defined as "localized agrifood systems". We based this work on the analysis of 18 localized agrifood systems in the Rhône-Alpes region (France). First, it presents the dynamics of construction and organization of these agrifood systems: diversity of actors involved, relationships between actors and rules that have been gradually established. We used the concept of geographical and relational proximity to analyse these supply chains and to highlight the mechanisms implemented to address the limits of short supply chains, particularly an increasing number of intermediaries. Then we assessed their performances with regard to...

Autores: Frederiksen, Pia; Langer, Vibeke.
Omlægning til økologisk jordbrug er ujævnt fordelt mellem landets amter. Dette hænger sammen med faktorer som bynærhed, bedriftstyper og den regionale indsats, der er gjort for økologien. Men også på lokalt niveau er der en ujævn fordeling af de økologiske bedrifter. Det kan fx skyldes en negativ betydning af sociale barrierer for omlægning, men også en positiv betydning af ildsjæle blandt såvel producenter som rådgivere.

Long and short term changes incrop yield and soil properties induced by the reduction of soil tillage in a long term experiment in Switzerland
Provedor de dados: 21
Autores: Büchi, Lucie; Wendling, Marina; Amossé, Camille; Jeangros, Bernard; Sinaj, Sokrat; Charles, Raphaël.
To address the inﬂuence of soil tillage reduction on crop yield and soil properties, an experiment was set up in 1969 in the western part of Switzerland. A conventional tillage treatment with plough was compared to a minimum tillage treatment and a deep non inversion tillage treatment, converted to no till in 2007. Evolution of crop yield through time was investigated, as well as the soil properties in 2013. Mean soil properties and their stratiﬁcation with depth were assessed. The results showed that, after 44 years, globally, all tillage treatments allowedtomaintainsimilaryieldsinthelongterm.However,duringthesametime,soilpropertieshavechanged deeply.

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...

Autores: López-Rayo, Sandra; Laursen, Kristian H.; Lekfeldt, Jonas D.S.; Grazie, Fabio D.; Magid, Jakob.
Urban waste products such as sewage sludge and organic household waste compost have a potential as fertilizers in agriculture, but evidence from historical field experiments performed in England and Germany with sewage sludge as fertilizer pointed towards negative effects of sludge-derived heavy metal accumulation on soil microbiota and plants. However, sewage sludge has improved in quality during the last half century and source separation of organic household waste has been shown to decrease the concentration of heavy metals in composts made from organic waste. This alongside a growing awareness on the benefits of an increased degree a recycling of nutrients from urban areas to agricultural soils led to the establishment of the CRUCIAL field trial in...

“Strategies” to sustain crop productivity by reducing the fertilizer and lime demands must be developed. The use of plant species that use more efficiently the soil nutrients and tillage systems that provide nutrients accumulation in more labile forms are prerequisites for sustainable agroecosystems. This study aimed to evaluate the long period effect of cultivating different winter species under different soil management systems on vertical distribution of soil nutrients and the soil acidity distribution in soil profile. The experiment was established in 1986 with six winter treatments (blue lupine, hairy vetch, oat, radish, wheat and fallow) under conventional tillage (CT) and no-tillage (NT) in a very clayey Rhodic Hapludox in Southern Brazil.

Long-term effects of cropping system on N2O emission potential
Provedor de dados: 21
Autores: Petersen, Søren O.; Ambus, Per; Elsgaard, Lars; Schjønning, P.; Olesen, Jørgen E.
The potential for N2O emissions outside the main growing season may be influenced by long-term effects of cropping system. This was investigated by collecting intact soil cores (100 cm3, 0-4 cm depth) under winter wheat in three organic cropping systems and a conventional reference within a long-term crop rotation experiment. Average annual inputs of C in crop residues and manure ranged from 1.7 to 3.3 Mg ha-1. A simulated freeze-thaw cycle resulted in a flush of CO2 during the first 48 h, which could be mainly from microbial sources. Other samples were adjusted to approximately –10, -30 or –100 hPa and amended with excess 15NO3- prior to freezing and thawing. Denitrification was the main source of N2O during a 72-h incubation at 22C, as judged from N2O...

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...
