El maíz (Zea mays L.) en México es importante social, cultural y económicamente. En el municipio de Molcaxac, Pue. la mayor parte de los productores utilizan poblaciones locales de maíz. Sin embargo, no existen estudios en la zona que describan la diversidad y potencial de las poblaciones locales de maíz, y las condiciones socioeconómicas en que se da la producción de este grano. La presente tesis se dividió en dos partes. La primera  tuvo como objetivos evaluar el rendimiento de grano y caracterizar agronómicamente la diversidad de las poblaciones locales de maíz existentes en el municipio de Molcaxac. La segunda parte tuvo como objetivo realizar una descripción general de las principales características de los productores de maíz, así como de su unidad...

Material embodiment and energy flows as efficiency indicators of soybean (Glycine max) production in Brazil
Provedor de dados: Engenharia Agrícola
Autores: Romanelli,Thiago L.; Nardi,Hudson de S.; Saad,Filipe A.
As the requirement for agriculture to be environmentally suitable there is a necessity to adopt indicators and methodologies approaching sustainability. In Brazil, biodiesel addition into diesel is mandatory and soybean oil is its main source. The material embodiment determines the convergence of inputs into the crop. Moreover, the material flows are necessary for any environmental analysis. This study evaluated distinct production scenarios, and also conventional versus GMO crops, through the material embodiment and energy analysis. GMO crops demanded less indirectly applied inputs. The energy balance showed linearity with yield, whereas for EROI, the increases in input and yield were not affected.

Provedor de dados: Horticultura Brasileira
Autores: Ragassi,Carlos Francisco; Carvalho,Agnaldo DF de; Silva,Giovani Olegário da; Pereira,Gabriel Emiliano; Pereira,Arione da S.
ABSTRACT Potato is responsive to intensive agricultural input use; however, it can be produced in less intensive production systems (such as the organic system) by using appropriate production techniques and genotypes adapted to this system. This study aimed to evaluate the performance of advanced potato genotypes for tuber yield under conventional and organic production systems, in order to select potential genotypes to become new cultivars adapted to these systems. Fifteen advanced potato clones and two controls were evaluated under organic and conventional production systems, in 2016 and 2017, in Brasília-DF, Brazil. The experimental design was randomized blocks with three replicates and plots composed of two rows with 10 plants each, spaced 0.35 m...

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

Autores: Dvorak, Petr; Tomasek, Jaroslav; Hamouz, Karel; Jedličková, Michaela.
In the area of potato production, targeted research solving concrete and actual problems of potato producers runs on Czech University of Life Sciences in Prague. In the last few years, we were focused on the production of new potatoes designated for early harvest, and we were focused on capitalization of yielding and qualitative characteristics of colored potato variety. These findings were further utilized and transferred to the system of organic farming. Firstly, we watched the influence of organic farming on yield and quality of tubers. Ecological ways of cultivation had strong negative influences on yield (decrease of 36%). From qualitative characteristics, organic farming increased the content of polyphenols by 10.2%, decreased the content of nitrates...

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: Organic Eprints
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...

Los pros y los contras del percarbonato de sodio
Provedor de dados: Organic Eprints
Autores: Pedersen, Lars-Flemming; Jokumsen, Alfred.
El artículo trata del uso de un agente desinfectante aprobado para acuicultura: percarbonato sódico (SPC). La substancia es un polvo que contiene peróxido de hidrógeno y es fácil de utilizar; cuando se añade a las instalaciones de los peces, el peróxido de hidrógeno se disuelve y se descompone formando oxígeno y agua. Este artículo presenta los resultados de mediciones realizadas en enero de 2017 tras una aplicación práctica en una granja de acuicultura orgánica. El estudio muestra que la aplicación de SPC resultó en una distribución uniforme de peróxido de hidrógeno en el agua, que se mantuvo durante unas pocas horas. Con el tratamiento se observó una liberación simultánea de oxígeno y también un incremento significativo del pH, algo que debe tenerse en...

Anaerobic digestion of residual liquid effluent (brown juice) from a green biorefinery
Provedor de dados: Organic Eprints
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...

Autores: Law-Ogbomo, K.E.; Osaigbovo, A.U.; Ogedegbe, S.
A field was carried out on an ultisol in humid area of Edo State, Nigeria to evaluate the effects of plant density and cattle dung manure application on soil nutrient status and okra pod yield. Treatments consisted of three levels of cow dung (0, 300 and 450 kg N ha-1) and three plant densities (47,619, 66,666 and 83,333 plants per hectare (pph)). A 3 x 3 factorial arrangement fitted into randomized complete block design and replicated three times. Data were collected on soil chemical properties and pod yield of okra. Routine analysis of the soil indicated that the soil was low in nutrient content, thus addition of cattle dung to the soil at various levels influenced the soil nutrient status positively. After cropping with okra, cattle dung application had...

Koens fysiologiske status og indflydelse heraf på produktion og sundhed omkring kælvning afhængig af foderniveau og næringsstofforsyning
Provedor de dados: Organic Eprints
Autores: Ingvartsen, Klaus Lønne; Mogensen, Lisbeth; Larsen, Torben.
Selvforsyning er ikke et regelkrav, men i tråd med det økologiske nærhedsprincip, dvs. at arbejde mest muligt i lukkede næringsstofkredsløb og dermed en fodring baseret på udelukkende hjemmeavlede fodermidler dyrket inden for bedriftens eget arealgrundlag. Det nuværende regelsæt har en minimumsgrænse for grovfodertildeling: 60% af tørstof i den daglige ration, dog 50% af tørstof til køer mindre end 3 måneder fra kælvning. I forbindelse med regelsættet er der imidlertid en række spørgsmål vedrørende dyrenes sundhed og produktion. På den baggrund er der gennemført forsøg med det formål at belyse produktion og metabolske parametre for tre typer 100% økologiske rationer baseret på korn, rapsfrø og kløvergræs dyrket på et givent areal pr. ko.

In aquaculture sector, the most recent legislative framework regarding the organic production in Europe is the Commission Regulation (EC) 710/2009, where chapter for aquaculture animals include requirement for animal welfare conditions in husbandry and maximum stocking densities. In Italy, only ten farms are involved in the supply of certified organic fish and only some pilot projects were carried out for organic farming of different species. Therefore, the purpose of this research was to define or verify the principal standards for organic seabass farming,...

Simulation of nitrate leaching from an organic dairy crop rotation with different manure types and loads
Provedor de dados: Organic Eprints
Autores: Berntsen, Jørgen; Olesen, Jørgen; Petersen, Bjørn Molt; Eriksen, Jørgen.
Introduction  Management of nitrogen in dairy systems is especially difficult due to the use of organic manures and the residual effects of the pasture. During grazing a considerable build-up of soil N is often observed. Ploughing of the grassland is therefore followed by a large mineralization that might exceed the demand of the subsequent crop. This might lead to large amount of nitrate being leached. In addition, rotations dependent on organic manures rather than mineral fertilizers are believed to have a higher risk of nitrate leaching.     The study present results from simulations with the FASSET model (Berntsen et al., 2003) of nitrate leaching and crop growth in organic dairy systems with two types of manures at two different stocking levels....

FEASIBILITY OF INTEGRATING ORGANIC MILK PRODUCTION INTO CERTIFIED SMALLHOLDER ORGANIC FARMS IN KIAMBU AND KAJIADO COUNTIES, KENYA
Provedor de dados: Organic Eprints
Autores: Odhong', Charles.
Organic livestock production can be considered as a system of production that better fulfills animal needs, promotes use of organic and biodegradable input for production and reduce the use of conventional veterinary treatments. As demand for organic dairy products increases in Kenya, especially in Nairobi, so does the need to supply the growing demand. Increased diversification of organic production is needed to meet the growing demand. The objective of this study was therefore to investigate the potential, challenges and feasibility of integrating organic milk production in smallholder crop-livestock farms in Kiambu and Kajiado counties of Kenya and validate the efficacy of Tephrosia vogelii Hook., Tephrosia villosa Pers., and Carica papaya Linn. leaves...

Biologische Helminthenkontrolle bei Weidetieren mit nematophagen Pilzen
Provedor de dados: Organic Eprints
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....

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

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

Antiparasitic activity of chicory (Cichorium intybus) and its natural bioactive compounds in livestock: a review
Provedor de dados: Organic Eprints
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...

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

The current performance of organic farms in relation to animal health often does not surpass the level of conventional production and does not always meet the self-proclaimed aims and the expectations of the consumers. Taking into consideration the specific characteristics of multi-factorial diseases and the need for appropriate living conditions, the question arises which obstacles are decisive for the current situation and need to be changed in order to improve animal health status.   Taking the system approach of organic farming into account, several theses in relation to the most relevant obstacles are discussed. Obstacles seem to be evident in relation to deficits concerning the perception of health problems, lack of a clear goal in relation to the...

Autores: Gordon, Susan H; Forbes, Michael J.
Whether chickens will make proper use of pasture is a problem experienced by producers of free-range and organic chickens. The aims of this project are to identify husbandry techniques and aspects of system design that encourage good pasture use. Two studies have been conducted comprising a winter and a summer flock. The aim of the winter flock was to examine the effect of outdoor artificial shelter on pasture usage. This was done for female Ross 308 birds grown to day 56, and ISA 657 birds grown to day 81. In summer, ISA 657 birds were grown to day 81. Treatments were either standard or enriched brooding, with pasture only or enriched pasture. Standard brooding was in a controlled environment house until day 42. Enriched brooding was in naturally...

Wenn die Schweiz darauf verzichtet, genmanipulierte Pflanzen in die Umwelt freizusetzen, so ist dies vor allem auch eine grossartige Marktchance für die Schweizer Landwirtschaft. Denn Gentech-food ist out, in ganz Europa. Die Schweiz könnte dann das liefern, was eine große Mehrheit gerne möchte: naturnahe und gentechfreie Lebensmittel.  Die Frage ist bloß: Kann sich die Schweizer Landwirtschaft einen Verzicht auf Gentechnik leisten? Dieser Frage ist die Studie "Zukunftsmodell Schweiz - eine Landwirtschaft ohne Gentechnik?" nachgegangen. Untersucht wurden die sechs Kulturen Kartoffeln, Weizen, Mais, Raps, Salat und Reben.  Gentechnische Lösungsansätze und die wichtigen Anbauprobleme der Schweizer Landwirtschaft sind sehr oft nicht deckungsgleich. Die...

Com o enfoque de sustentabilidade, o manejo passa a ser o principal fator a ser utilizado na manutenção e perenidade dos pastos, e, por conseqüência para a condução dos animais em pastoreio. Para que isso ocorra Voisin postulou quatro leis básicas, sendo a primeira relacionada ao Tempo de Repouso adequado, que permita à planta armazenar em suas raízes reservas suficientes para um novo e vigoroso rebrote. A segunda lei prevê que o Tempo de Ocupação de um piquete pelos animais deve ser suficientemente curto para que uma planta não seja pastoreada mais de uma vez em um mesmo período de pastoreio. A terceira lei tem como meta os Rendimentos Máximos, para isto é preciso ajudar os animais que tenham as maiores necessidades nutricionais na obtenção de alta...

Autores: Høgh-Jensen, Dr Henning; Pedersen, Morten B.
A decrease in the use of fertilizers and a decrease in soil fertility direct the research focus towards the ability of the crops to adapt to low potassium conditions and to their ability to utilise sparingly soluble potassium sources. Pea (Pisum sativum), red clover (Trifolium pratense), lucerne (Medicago Sativa L.), barley (Hordium vulgare), rye (Secale cerale), perennial ryegrass (Lolium perenne L.), and oilseed rape (Brassica napus oliefera) were grown in thin layers of soils to study their root morphological plasticity and ability to utilise different potassium pools at 26 and 60 mg exchangeable K kg-1 soil. The legumes (pea, red clover, lucerne) accumulated larger amounts of nitrogen but lower amounts of potassium than rye, ryegrass, barley, and...

Autores: Pers Berglund, Anna.
In order to assess the weed suppressive ability of a pea/barley crop mixture and the component crops in sole cropping, a controlled outdoor experiment was performed at The Swedish University of Agricultural Sciences, Ultuna, Sweden, in the summer of 2015. A substitutive completely randomized ex-perimental design was used with seven treatments and six replicates. The weed species planted in the experiment was Elytrigia repens (L.) Desv. ex Nevski. At three occasions leaf area index (LAI) was optically measured using a LAI-2200C Plant Canopy Analyzer. Two destructive harvests were taken in order to assess the biomass of different plant parts from each of the component species. At the first harvest leaf area was measured in order to calibrate the optical LAI...

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

Anthelmintic activity of forage chicory (Cichorium intybus) and field efficacy of ivermectin against gastrointestinal nematodes in Danish cattle
Provedor de dados: Organic Eprints
Autores: Peña-Espinoza, Miguel.
Parasitism with gastrointestinal (GI) nematodes is ubiquitous in grazing cattle and its control is critical to sustain satisfactory levels of animal health, welfare and productivity. Currently, conventional parasite control strategies relying exclusively on anthelmintic drugs are severely threatened by the development of anthelmintic resistance (AR) in bovine nematodes in several countries. In Denmark, cattle farmers and their veterinarians depend largely on macrocyclic lactones (ML), mainly ivermectin (IVM), for nematode control. However, no studies have evaluated the field efficacy of IVM against GI nematodes in Danish cattle. Alternative control approaches to minimize selection for AR and that can complement the use of the still effective anthelmintics...

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...

Provedor de dados: Organic Eprints
Autores: Rinne, Marketta; Dragomir, Catalin; Kuoppala, Kaisa; Marley, Christina; Smith, Jo; Yanez Ruiz, David.
This literature review evaluates the potential of a range of by-products from the agricultural,greenhouse, forestry, food processing and bioenergy sectors and agro-forestry  systems as feed components in organic and low input dairy systems. The variability of the raw materials further modified by differing processing methods results in wide range of feed materials available. Innovative use of novel and underutilized feed resources has the potential to improve the efficiency of the “green economy”.

Autores: Solemdal, Liv; Ebbesvik, Martha.
Ut fra ei tidsrekke på over 20 år, er det ikke store endringer i engavlinger etter omlegging til økologisk drift ved Tingvoll gard. Avlinga varierer og det er interessant å følge med om avlingsnivået ved første og andre slått fortsatt vil ha en svak nedadgående trend, eller om det har stabilisert seg i forhold dagens driftsopplegg og slåtteregime. I tillegg til å analysere innholdet av næringsstoffer i jorda er det viktig å sørge for at kløveren trives, at det ikke blir for mye ugras og at enga fornyes ofte nok for å opprettholde avlingsnivået.  Tallmaterialet fra Tingvoll gard dokumenterer en god ressursutnytting regnet ut fra næringsbalanse per daa og nitrogen-effektivitet. Disse parametrene peker likevel mot et større overskudd av næringsstoffer de...

Influence of grouping strategy on welfare measurements of organic entire male pigs
Provedor de dados: Organic Eprints
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...

Extrato de alho melhora a superação da dormência de videiras ‘Niagara Rosada’em regiões subtropicais.
Provedor de dados: Organic Eprints
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.

Autores: Hörning, B.; Aigner, S.; Aubel, E.; Schubbert, A.; Simantke, C.; Bussemas, R.; Trei, G.
Fazit:    Die gegenüber früheren Untersuchungen gestiegenen Bestandsgrößen weisen darauf hin, daß sich im ökologischen Landbau ein ähnlicher Strukturwandel wie in der konventionellen Landwirtschaft vollzieht (Wachstum und Spezialisierung). Die Auswertung zeigt ferner, daß die Betriebe zunehmend bemüht sind, bereits jetzt den zukünftigen Haltungsvorschriften der EU-Verordnung zu entsprechen. Fast alle Betriebe führen Weidegang durch und trotz der relativ geringen Bestandsgröße haben die meisten Betriebe bereits Laufställe; Auslaufmöglichkeiten fallen demgegenüber allerdings noch ab.

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...

Nitrate leaching and N2-fixation in grasslands of different composition, age and management
Provedor de dados: Organic Eprints
Autores: Eriksen, J.; Vinther, F.P.
Cut grassland systems usually have high N efficiency and consequently low nitrate leaching, whereas the introduction of grazing animals increases the loss potential dramatically (Jarvis, 2000). It has been demonstrated that nitrate leaching from unfertilised grass-clover swards is lower than from mineral-N fertilised swards grazed by cattle. The possible explanation for this is that the N2 fixation by pasture legumes is regulated by a natural feedback mechanism driven by soil inorganic N levels. The feedback mechanism acts as a limit to N inputs from legumes and consequently regulates the potential for N losses (Ledgard, 2001).  In this paper we report 5 years (1997-2002) of nitrate leaching from four cropping sequences with different grassland frequency...

Provedor de dados: Organic Eprints
Autores: Verwijst, Theo; Lundkvist, Anneli; Krawczyk, Roman; Kaczmarek, Sylvia.
The aim of WP2 is to assess the weed suppressive ability of crop mixtures as a function of species and densities, using a functional approach. During 2016, field experiments and controlled experiments with mixtures of barley and pea were conducted in Sweden and Poland. The performance of crop mixtures was compared to the performance of pure crops with regard to their ability to suppress weeds. In the fields, natural weed populations were used while the controlled experiments employed Elytrigia repens or Sinapis alba as a model weed. The purpose was to quantify weed suppressive ability of the crops, the impact of weeds on crop yield, and to identify crop traits responsible for the effects on weeds and crop yield.     Preliminary results from the controlled...

Infection models with Flavobacterium psychrophilum
Provedor de dados: Organic Eprints
Autores: Madsen, Lone; Dalsgaard, Inger.
High mortalities among rainbow trout (Oncorhynchus mykiss) fry are often the result of infections caused by Flavobacterium psychrophilum, and in Denmark this pathogen can be found in nearly all freshwater fish farms. The infection can be treated with antibiotics, but lower sensitivity against the infection is an increasing problem for some of the used drugs, wherefore alternative treatment methods (e.g. bacteriophages) are investigated. Prophylactic measures (e.g. feed additives) are another approach, so infections with the bacterium can be avoided, before they become a problem. No matter if the focus is on prophylactic or alternative treatment, reliable infection models are needed to evaluate the treatments as well as to get more knowledge about...

Udbyttet i de forskellige sædskifter afhænger mest af jordtype og gødskning. Kløvergræs som grøngødning øger udbyttet i vinterhvede, dog ikke på grovsandet jord. Sædskifter med og uden grøngødning er økonomisk ligeværdige, når omkostninger til maskiner og arbejde tages i betragtning. Helårsgrøngødning er særlig relevant for at forebygge problemer med rodukrudt.

Gulerod (Daucus carota L. subsp. Sativus (Hoffm.) Thell) er en toårig plante og reproduktiv vækst (frøproduktion) sker efter en periode med kort daglængde og lav temperatur (vernalisering). I grønsagsproduktionen (1. år) tilskyndes hurtig rodvækst og gulerodens udvikling frem til færdigt produkt kan gennem- føres i en relativ kort vækstsæson. Frøproduktion (2. år) af gulerod kræver derimod en lang vækstsæson, hvor frøene modner på planten typisk i august-september.       Før i tiden blev frø af sent modnende arter såsom gulerod og kål produceret i Danmark, men i dag foregår denne produktion fortrinsvis i Frankrig og Italien, fordi man dér undgår den sene, våde høst, der kan forringe frøkvaliteten, særligt på grund af svampeangreb.

There is a need for integrating the biomass starting point into the energy manufacturing steps. It will secure that bioenergy is produced with limited use of non-renewable fossil fuel to secure that in the application of biomass a net emission reduction of green house gasses take place along the whole chain.  Intercropping, defined as the cultivation of two or more species simultaneously on the same area of land, is an traditional practice still widespread in the tropics and common in developed countries before the ‘fossilization’ of agriculture. This cropping strategy is based on the manipulation of plant interactions in time and space to optimize resource use and productivity.

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

Management practices’ effect on milk production, somatic cell count and mastitis in Swedish organic dairy farms
Provedor de dados: Organic Eprints
Autores: Wingren, Josefin.
The most common animal health problem in organic dairy production is mastitis. It is considered to be one of the most serious welfare problem in dairy production, as well as an economic problem as it often leads to a reduced milk yield and reduced profit. To combat this problem, the focus in organic dairy production is laid on management strategies to e.g. reduce the use of antibiotics and improve the animal health and welfare. In 2015, the EU-funded project OrganicDairyHealth started in seven European countries, including Sweden. Within the project, an extensive survey on housing, management, health and production was sent out to organic dairy farmers in each country, and this thesis is based on the data from the Swedish survey. This master thesis’ aim...

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

Results from field experiments in 2000 and 2002 showed that intercropping of perennial ryegrass and green manure legumes prolonged the time for nitrogen accumulation in the grass seed crop. The effect on the grass seed yield was dependent on the green manure legume species. However, using the intercropping technique it was possible to achieve seed yield at 1012 kg ha-1 in 2000 and at 829 kg ha-1 in 2000, which is very promising for the future organic seed production of perennial ryegrass.

The core task of sustainable milk production is the conversion of forage into milk, dairy products and, as a by-product, into meat. In Europe and North America, for decades dairy cows were selected for a high genetic merit for milk production under high input farming conditions. It is therefore questionable whether these "high input genotypes" are suitable for forage-based, organic farming systems. The objective of this study was to compare two cow types concerning their suitability for an Alpine organic, low input dairy production system. The cow types used were conventional Brown Swiss (BV) on the one hand and a specific strain of Holstein Friesian (HFL), selected for lifetime performance, on the other. Both cow types were managed within one herd in an...

Diversity of organic livestock systems in Europe
Provedor de dados: Organic Eprints
Autores: Roderick, Steve; Padel, Susanne; Younie, David.
There is significant diversity in livestock production across Europe, as a consequence of a range of climatic, historic and economic factors. Yet there are common standards and goals. Enlargement of the European Union has added emphasis to the importance of this diversity. Statistics representing the recent development of organic farming illustrates the considerable variation across the continent in relation to land use and the main animal species farmed. This paper examines some of the climatic and historical impacts of a diverse Europe and recom-mends a degree of flexibility in the adoption of or-ganic standards.

Symbiotisk N2 fiksering i kløvergræs
Provedor de dados: Organic Eprints
Autores: Vinther, F.P.
Bælgplanter, herunder de forskellige kløverarter, kan ved knoldbakteriers hjælp (symbiose) optage luftens kvælstof (N2) og derved udnytte denne uudtømmelige kvælstofkilde. Processen er ganske enkelt forudsætningen for at kunne drive økologisk jordbrug, og det har derfor stor interesse at kende størrelsen af N-fikseringen og få et bedre kendskab til de faktorer som har betydning for processen. Derved bliver det muligt at optimere produktiviteten og reducere eventuelle miljømæssige effekter af et givet dyrkningssystem.

Searching the critical soil organic carbon threshold for satisfactory tilth conditions – test of the Dexter clay:carbon hypothesis
Provedor de dados: Organic Eprints
Autores: Schjønning, P.; de Jonge, L.W.; Moldrup, P.; Christensen, B.T.; Olesen, J.E.
The concern for deteriorating soil structure at low soil organic matter (SOM) contents calls for better knowledge of SOM interaction with soil minerals as well as guidelines for soil conservation. We measured clay dispersibility in a field with a textural gradient. Our results support the concept of differentiating soil content of clay in a complexed and non-complexed part although our data did not point out an exact clay/OC ratio threshold. Our results also indicated that labile fractions of SOM may play an important role in soil physical behavior. We revisited literature data and found evidence that soil content of fines (&lt;2 or &lt;20 μm) is a major determinant of soil specific surface area (SA). We noted that soil SA coverage with SOM changed...

Intercropping grain peas with barley
Provedor de dados: Organic Eprints
Autores: Alföldi, Thomas; Clerc, Maurice; Stöcklin, Milo.
Intercropping of legumes with cereals is a promising possibility to produce fodder protein while creating few costs and using few resources.    Practicable cultivation methods of intercropping with protein peas/barley and field beans/oats were developed, both with mixing ratios of 80% and 40%, respectively, of the usual local seeding amount for the single crop (possible for winter crops as well as for spring crops).     The grain serves as a support crop, suppresses weeds and provides a risk coverage in years of poor grain legume development.    Since 2010, the acreage of organic peas and beans, mostly grown in mixed cultures, has multiplied.     This increase was also possible due to mills that buy and separate the yield of intercropping systems into its...

Autores: Jokumsen, Alfred; Gesto, Manuel; Buchmann, Kurt; Lorenzen, Niels; Pedersen, Lars-Flemming; Henriksen, Niels Henrik; Schmidt, Jacob; Madsen, Lone; Kania, Per; Pedersen, Per Bovbjerg.
Rainbow trout farming and in particular organic rainbow trout farms are critically challenged by the relatively high prevalence of skin/gill infections caused by various pathogens, especially the parasite Costia (Ichthyobodo necator) and amoebae, which are ultimately lethal for fry/smaller fish. In addition, a Midichloria-like bacterium causes the non-lethal skin disease Red Mark Syndrome (RMS), which results in downgrading/rejection of up to 30% of the fish when placed on the market. Treatment by use of antibiotics/parasitics/ auxiliary compounds is only possible to a limited extent in organic trout production. Hence, solutions to prevent and/or treat costia, amoebae and RMS are urgently needed, not only to secure production of organic rainbow trout in...

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: Organic Eprints
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...

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

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

Mælkens indhold af CLA er interessant ud fra en human ernæringssynsvinklen, idet flere undersøgelser har vist en positiv sammenhæng mellem indtag af CLA og risikoen for cancer. Der blev fundet en betydelig variation mellem bedrifter i mælkens indhold af CLA, og ikke noget entydigt billede af niveauet i konventionel og økologisk mælk. Resultater viser desuden at foderrationens sammensætning påvirker niveauet, men også at der synes at være en forskel mellem de enkelte køer.

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

In a long-term field trial in Therwil, Switzerland, the bio-dynamic, bio-organic and conventional farming systems were compared (DOC trial). The present paper focuses on long-term yield development and on product quality of beetroot. Due to the favourable climate and soil, beetroot yields were generally high. The yield of beetroot in both biological systems was about 75 % that of the conventional system, but the input of nitrogen and potassium was about 60 % lower.

Autores: Ivanova-Peneva, Sonya; Aarnink, Andrè; Verstegen, Martin.
The main aim of this study was to quantify nutrient deposition on the paddock in Dutch organic pig farms. Observations of excreting behaviour of grazing sows were carried out at three farms in each of two measuring seasons (spring/summer and autumn). The nutrient loads of N, P and K were calculated according to their content in urine and faeces, average weight of urine and faeces per excretion, and number of urinations and defecations done in the paddock. The N and P loads on the paddock varied greatly between the organic pig farms (P&lt;0.01 for N, not significant for P and P&lt;0.05 for K).  The total amount of nutrients on two of the farms far exceeded the permitted levels (170 kg.ha-1year-1 for N and 44  kg.ha-1year-1 for P). On all three farms, faeces...

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

Provedor de dados: Organic Eprints
Autores: Hansen, Sissel; Bakke, Haavik, Torleiv; Bergslid, Ildri (Rose) Kristine; Elvatun, Helena; van Gool, Bart; Lunnan, Tor; Røthe, Gunnhild; Walland, Finn.
I denne rapporten presenterer vi seks gårder som viser at det er mulig å forene god økonomi med en miljømessig bærekraftig produksjon, men økonomien var best på de største gårdene. Felles for alle gårdene er næringsrik jord med god jordstruktur og god drenering, fokus på agronomi og godt husdyrstell. Dette resulterte i gode avlinger, god utnytting av tilførte næringsstoff, moderat bruk av energi og moderate utslipp av klimagasser. Fra observasjoner på disse gårdene og diskusjon på arbeidsseminar med gårdbrukerne, prosjektgruppe og inviterte gjester kan vi tipse om noen tiltak for miljøvennlig melkeproduksjon: god drenering, lite kjøring på våt jord, utføre jordarbeiding, gjødsling og høsting straks været og jorda er egnet, slepeslange med stripespreder i...

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

Nitratudvaskning fra økologiske og konventionalle planteavlsbedrifter - simuleringer med FASSET bedriftsmodellen
Provedor de dados: Organic Eprints
Autores: Berntsen, J.; Petersen, B.M.; Kristensen, I.S.; Olesen, J.E.
Med udgangspunkt i regnskabsdata fra Fødevareøkonomisk Institut (FØI) og data fra Centrale Registre (CR) blev importen af kvælstof (N) i gødning til marken til konventionelle og økologiske planteavlere estimeret til hhv. 129 og 51 kg N ha-1 år-1. Desuden blev der med udgangspunkt i den aktuelle afgrødefordeling opstillet et generelt sædskifte for hver af de to systemer. Det opstillede sædskifte for den økologiske planteavl havde en høj andel af vårsæd og desuden 20% kløvergræs, mens den konventionelle planteavl var domineret af kornafgrøder primært i form af vintersæd. Med baggrund i disse model-sædskifter blev N-balancen på markniveau beregnet ved anvendelse af FASSET modellen. Dette inkluderede også N-udvaskning og ændring i jordens Npulje. Alle...

Autores: Norup, Liselotte R.; Ricarda M., Engberg; Steenfeldt, Sanna; Horsted, Klaus; Juul-madsen, Helle Risdahl.
Naturlig modstandskraft er vigtig i fremtidens økologiske produktionssystemer for at opfylde markedets krav og forbedre den overordnede produktivitet. Men udviklingen af et robust immunsystem vil sandsynligvis være på bekostning af andre funktioner såsom vækst og reproduktion. I Organic RDD projektet SUMMER har man undersøgt tarmsundhed og immunsystem hos forskellige afstamninger af slagtekyllinger  med forskellige vækstpotentialer Deimmunologiske undersøgelser viser, at der er forskel på de basale immunfunktioner mellem afstamningerne. Den afstamning med det laveste vækstpotentiale SU51 ser ud til at have et mere robust immunsystem end den afstamning med det største potentiale JA757.

Seed to seed - strenghtening the agricultural production in rural communities
Provedor de dados: Organic Eprints
Autores: Deleuran, L.C.; Boelt, B.
A common assumption is that the quality of the seeds used in many developing countries is poor. Yet, the factors supporting this assumption are not specifically known. Many small farmers in developing countries keep a portion of own produced seed and are very much aware of its importance. However, due to often limited resources the seeds are not given the attention it needs in terms of production, preservation and utilisation. These factors sum up to an unsatisfactory seed quality leading to low agricultural production.  In times of disaster, farmers end up selling or consuming all their seeds and for their next harvest they need to be able to purchase seeds. In many rural areas quality seeds are not available. When buying seeds, the farmers are in most...

Forlænget kælvningsinterval - kan være en fordelagtig produktionsstrategi
Provedor de dados: Organic Eprints
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...

Organic and alike farming in Latin America: state and relevance for small-scale livestock keepers
Provedor de dados: Organic Eprints
Autores: Siegmund-Schultze, Marianna; Valle Zárate, Anne.
While the organic movement is growing, its contribution to small-scale livestock farm-ing in Latin America is contentious. Secondary literature and available statistics were used for this study. Farms and area under certified organic agriculture are rising, but small-scale livestock farming is little represented. The latter is yet to be found in non-certified organic-like farms, offering locally adapted paths to securing livelihoods.

Provedor de dados: Organic Eprints
Autores: Spoolder, H.
Results obtained in the QLIF subproject 4 have provided recommendations to farmers and stakeholders on how to improve organic livestock farming. Progress was made in areas of housing, feeding and management. Often the recommendations are straightforward, and ready for implementation. In other areas challenges remain. In some cases, progress with respect to one objective has created new challenges. In these cases it is difficult to decide whether a change is an overall improvement or not. This leaflet includes a focus on means to prevent and control parasitic infections in pigs and poultry, e.g., by inclusion of dried chicory roots in the diet of sows and boars to reduce the level of roundworm infections. Further, it is stressed that control of Ascaris suum...

Six years results from an organic vegetable crop rotation aimed at self-sufficiency in nitrogen
Provedor de dados: Organic Eprints
Autores: Thorup-Kristensen, Kristian.
One of the main constraints of organic vegetable production is lack of available N, which causes reduced yields and quality of the to the crops. Therefore, we started an organic vegetable crop rotation in 1996 where we could study the possibilities for improved N utilisation. The N supply to the crops is based on the effects of nitrogen catch crops, green manure crops and crop sequences aimed at a high utilisation of precrop effects, whereas no input of any manures are made. Measurements and experiments have been made within the crop rotation to test the effectivenes of the N strategies used.   The results show that it have been possible to maintain good yields of the crops in the rotation. Yields of leek and carrot have been as high as in conventional...

Organic livestock production
Provedor de dados: Organic Eprints
Autores: Sundrum, Albert.
The development towards a sustainable agriculture has been a main objective of organic agriculture from the beginning (IFOAM, 1978), and a declared objective of the newly applied EC-Regulation (1804/1999) on organic livestock production which provides a clear framework for livestock production. The leading idea is based on the voluntary self-restriction in the use of specific means of production with the objectives to produce food of high quality in an animal appropriate and environmentally friendly manner within a nearly complete nutrient farm organism (Sundrum, 1998). With regard to an environmentally friendly production, organic livestock farming is characterised by:   - System-oriented approach,   - Renunciation of mineral nitrogen, pesticides, growth...

Mitigating greenhouse gas emissions from paddy farming by intercropping with other economically useful plants
Provedor de dados: Organic Eprints
Rice is a major staple food crop and a significant natural source of greenhouse gas (GHG) emissions. A major increase in the production of rice will be indispensable in order to feed the burgeoning global population and in turn the GHG emissions –particularly methane and nitrous oxide – are expected to increase, unless new mitigation strategies are developed and applied.  This project explores the potential for developing new rice based cropping system integrated with novel strategies to mitigate GHG emissions. There are a number of aquatic plant species, which exists naturally in rice producing regions and are already part of human consumption in local cultures. We plan to test these plant species for their potential to reduce emissions of methane and...

The crop to be incorporated was a frost susceptible green manure that spontaneously grassed and looked like an old ley. The ground was very dry.   The film shows the following plow dethatchers at work:    • Bugnot 52 Rapidlab  • Mini-8 OVLAC  • Escudero Adero  • Kverneland Ecomat  • Traditional Operating plow    Under wet conditions, the shallow tillage without soil-turning (= with crow's feet dethatchers for example) does not provide an absolutely clean soil. It’s the same with a superficial and complete reversal of a ley.   One strategy would be to till soil superficially (= 3 - 4 cm for example) with crow's feet or cultivator blades to dry vegetation, then moving a disc harrow plow, which, even without causing complete reversal would leave behind a...

Comparison between dual-purpose  and specialized dairy cattle  in pasture-based systems:  change in body condition, locomotion score and cleanliness  from summer to winter season
Provedor de dados: Organic Eprints
Autores: Scholl, Francisca.
This study is an exploratory research comparing the changes of body condition score, locomotion score and cleanliness score between pasture and indoor season in purebred Dutch Friesian, 75% Dutch Friesian, 50% Dutch Friesian, Holstein Bakels and Brown Swiss dairy cattle. The dual-purpose cows were expected to cope better with a change in season and harsher environmental conditions compared to specialized dairy cows. Therefore it was expected that the body condition of the dual-purpose cows would be closer to the optimum or even higher and would barely change over season. The specialized dairy cows were expected to cope less well on pastures and during a change of season, with a body condition under the optimum, higher prevalence of lameness and more dirt...

Estima-se que no Brasil as perdas anuais causadas por pragas durante o armazenamento de grãos equivalem a 10% da produção. O mercado tradicional fornece agrotóxicos para o controle, mas os produtores de base ecológica têm poucas alternativas. Assim, foi objetivo do trabalho verificar a eficácia dos subprodutos do xisto no controle de S. zeamais em sementes de milho. Empregou-se pós de xisto retortado, finos de xisto, calxisto e cinza de xisto (2 e 5 Kg/1000 Kg de sementes), terra diatomácea e testemunha não tratada. Os ensaios foram conduzidos em delineamento inteiramente casualizado, três repetições por local e época de avaliação. A mortalidade foi verificada bimestralmente até 180 dias.

A randomized controlled trial to compare the use of homeopathy and internal Teat Sealers for the prevention of mastitis in organically farmed dairy cows during the dry period and 100 days post-calving.
Provedor de dados: Organic Eprints
Autores: Klocke, P.; Ivemeyer, S.; Butler, G.; Maeschli, A.; Heil, F.
Introduction: Routine use of antibiotics to prevent mastitis in dairy cows is prohibited by organic farming regulations. Internal Teat Sealers have been proposed as an alternative. We compared two drying-off (DO) supporting measures (Internal Teat Sealer and Homeopathy) to an untreated control group to assess their protective effects against clinical mastitis and intra-mammary infections during dry period of dairy cows.  Methods: A field trial with 102 dairy cows from 13 Swiss organic dairy farms was conducted. Cows were randomly assigned to one of three groups within a herd. In the Internal Teat Sealer group (ITS; 36 cows) cows were treated with the commercial ORBESEAL (Pfizer) in all four quarters immediately after the last milking. In the Homeopathy...

Verfahrenstechnische und systemorientierte Strategien zur Emissionsminderung in der Nutztierhaltung im Vergleich [Procedural and system-orientated strategies for reducing emissions in livestock production]
Provedor de dados: Organic Eprints
Autores: Sundrum, Albert.
Zusammenfassung:    Im Bemühen um eine Reduzierung von Emissionen aus der landwirtschaftlichen Nutztierhaltung konkurrieren unterschiedliche Strategien im Hinblick auf Effektivität, Umsetzbarkeit und Nachhaltigkeit. In der herkömmlichen Tierproduktion kommen vorrangig solche Strategien zum Einsatz, bei denen der Austrag betrieblicher und importierter Nährstoffe in nachgelagerten Bereichen der Prozesskette mit Hilfe verschiedener Verfahrenstechniken reduziert wird. Demgegenüber basiert der systemorientierte Ansatz in der Ökologischen Tierhaltung auf dem Vermeidungsprinzip. Dabei wird auf risikobehaftete Produktionsmittel verzichtet und über eine gezielte Verknappung von Ressourcen der Nährstoffinput in den landwirtschaftlichen Betrieb drastisch gesenkt....

Extended lactation may improve cow health and productivity and reduce greenhouse gas emission from organic dairy cows
Provedor de dados: Organic Eprints
Autores: Lehmann, Jesper Overgård; Mogensen, Lisbeth; Kristensen, Troels.
The concept of extended lactation is supposed to improve cow health and productivity and at the same time reduce greenhouse emission from high-yielding organic dairy cows in a product perspective. This effect is achieved through fewer calvings per year and hence a production of fewer replacement heifers, which then reduces the annual herd requirement for feed. We believe that the average milk yield per feeding day – days lactating plus days dry – per cow will be unchanged. However, this requires that the average cow will have to produce milk for a longer timeframe, and thus they will become older before being culled. We believe this will be a derived effect of the improved cow health as the majority of disease incidences occur around the time of calving....

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

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

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

This report was presented at the UK Organic Research 2002 Conference. In order to develop organic dairy production a system study called “The Öjebyn Project” was started in 1990. Öjebyn is a research station of The Swedish University of Agricultural Sciences in northern Sweden. There is 104 hectares of arable land; 58 hectares are grown organically and 46 hectares are grown conventionally. The feed produced on the farm was fed to around 50 dairy cows in each system. There has been a crop rotation of six years and a careful handling of farmyard manure and urine from the dairy cows. The crop yields have been recorded for twelve years as have the quality of each crop in terms of energy, protein and mineral content (P, K, Ca, and Mg). The difference in yield...

In Zukunft kann in der Milchviehhaltung eine weitere Differenzierung in der Intensität der Produktion zwischen den Betrieben erwartet werden. Dies muss auch in den Zuchtprogrammen eine Berücksichtigung finden. Der ökologische Gesamtzuchtwert ist ein Hilfsmittel für Milchviehbetriebe welche im Fitnessbereich und der Grundfutterlebensleistung ihren Schwerpunkt setzen und demgegenüber auf Frühreife, hohe Einsatzleistungen und Höchstleistungen verzichten möchten. In Österreich besteht von Bio-Austria und vom Bio-Institut des LFZ das Bestreben, den ökologischen Gesamtzuchtwert entsprechend dem Bayrischen Modell vollständig zu etablieren. Derzeit können die ÖZW-Zuchtwerte von Zuchtstieren für die Rassen Fleckvieh, und Braunvieh über die Homepage des...

Autores: Nalubwama, Sylvia; Vaarst, Mette; Kabi, Fred; Kiggundu , Muhammad.
Ninety certified organic pineapple producers were interviewed using a semi-structured questionnaire in Luwero and Kayung districts in Uganda. Data was analysed using statistical package for Social Scientists (SPSS). Results indicated that most organic farmers (81.1%) kept mostly cattle in combination with others species (goats, pigs and chickens). There was no significant difference (P&gt;0.05) in the numbers of pigs, poultry and chickens owned per farm in the two districts but there was significant difference (p=0.017) in the numbers of cattle. 62% of the farmers had indigenous breeds of cattle, 97.8% had goats, 87.5% had pigs and 100% of farmers had indigenous chickens. Crop residues formed bulk of feed for cattle (63.2%) and pigs (46%). Goats mostly...

Positiv effekt af kamdyrkning
Provedor de dados: Organic Eprints
Autores: Henriksen, Christian Bugge.
Det netop afsluttede FØJO-II projekt CARMINA har givet følgende hovedresultater: Pløjefri dyrkning kombineret med kamme opsat om vinteren kan reducere udvaskningen af kvælstof på lerjord og er et muligt alternativ til almindelig kartoffeldyrkning. Dybe jordløsninger i vækstsæsonen kan under gunstige omstændigheder øge udbyttet i kartofler. Endvidere har kamdyrkning efter pløjning vist potentiale til at øge udbyttet i majs.

Nitrogen utilization in integrated crop and animal production
Provedor de dados: Organic Eprints
Autores: Seuri, P.
The principles of organic production are based on integration between crop and animal production and self-regulated nutrient intensity. A comparison between specialized dairy and crop farm models and an integrated dairy and crop farm model showed 24 % higher total production per area and higher nitrogen utilization in the integrated system. The main factors were more efficient nutrient circulation, better utilization of legume crops and low intensity of nitrogen on non-legume crops.

Farmland biodiversity and agricultural management on 237 farms in 13 European and two African regions. Data Paper.
Provedor de dados: Organic Eprints
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...

Organic forage seed production
Provedor de dados: Organic Eprints
Autores: Boelt, Birte.
From January 2004 only organically produced seed can be used in organic farming systems within the EU. Optimal forage production relies on the access to improved cultivars of high quality clover and grass seed for forage mixtures. Currently the supply of organic forage seed in Europe i scarce. In Denmark a production of one of the main constituents of forage mixtures, perennial ryegrass (Lolium perenne L.) is established, however, another main constituent, white clover (Trifolium repens L.) is still in request.  In general seed yield in organic production is decreased compared to conventional production. In perennial ryegrass the seed yield reduction is approximately 25% whereas it similarly are 80% in white clover. Until now research initiatives has not...

Økologisk kvalitet skal retfærdiggøre merpris
Provedor de dados: Organic Eprints
Autores: Hermansen, John E.; Horsted, Klaus.
Den sortbrogede danske landrace er meget forskellig fra de moderne krydsninger.   Økologisk svinekød og økologiske kyllinger er betydeligt dyrere end tilsvarende konventionelle produkter. Derfor har mange forbrugere en forventning om, at de økologiske produkter adskiller sig fra de konventionelle - og at kvaliteten retfærdiggør merprisen.  Det er baggrunden for, at der i projektet: Kvalitet og integritet i økologiske æg-, kyllinge- og svinekødsprodukter undersøges strategier for mere forskelligartet svine- og kyllingeproduktion.

Autores: Entz, Martin; Welsh, Cathy; Tenuta, Mario; Chen, Yu Ying; Nelson, Alison; Froese, Jane.
A long-term field study was used to compare soil nitrogen and phosphorous status, and soil aggregate stability in organic and conventional cropping systems.  Two rotations were tested: a grain only and a grain-alfalfa hay rotation.  The organic systems had a lower nitrate leaching potential than the same rotations under conventional management.  After 13 years, one organic system (the grain-alfalfa; no manure return) is suffering serious soil P depletion. However, the grain only and the grain-alfalfa with manure return to land systems had soil P levels similar to the prairie grass control treatment and showed no signs of P deficiency. Despite having lower levels of organic carbon, the organic soils had higher levels of wet aggregate stability than...

ORGANOFINERY: A biorefinery for the production of organic protein rich feed for monogastric animals
Provedor de dados: Organic Eprints
Autores: Fernandez, Maria Santamaria; Uellendahl, Hinrich; Lübeck, Mette.
Nowadays, the organic farming sector is rapidly increasing in order to meet the increasing demand for organic products. However, the scarce availability of organic feed for monogastric animals together with the lack of organic fertilizers are challenging the development of this sector. In this context, a Danish project called Organofinery is focusing on developing a green biorefinery platform for the production of organic protein-rich feed for monogastric animals, of biogas and of organic fertilizer.  In the Organofinery concept, the freshly harvested green biomass is separated by a screw press into a green juice and a press cake. Soluble sugars contained in the green juice are fermented by specific lactic acid bacteria, leading to a drop of the pH and...

Performance of Organic Grain Cropping Systems in Long-Term Experiments
Provedor de dados: Organic Eprints
Autores: Teasdale, John R.; Cavigelli, Michel A.
Organic farming and conventional no-tillage farming systems share many of the same benefits from protecting and improving soils.  A review of recent results from two long-term systems experiments in the mid-Atlantic region of the U.S.A. demonstrates that organic cropping systems with organic amendments can increase soil carbon, nitrogen, and yield potential more than conventional no-tillage, despite the use of tillage in organic systems.  However, reduced-tillage organic systems present challenges for weed control, particularly with simple rotations typical of conventional grain cropping systems.  Organic systems that employ more complex rotations including a hay crop have demonstrated greater potential for improved weed control, increased nitrogen...

A NOVEL GREEN BIOREFINERY CONCEPT: Protein refining by lactic acid fermentation and biogas production from green biomass
Provedor de dados: Organic Eprints
Autores: Fernandez, Maria Santamaria.
The extraction of proteins from leaves, integrated in a green biorefinery, may represent an attractive solution to the increasing demand for protein-rich animal feeds while decreasing the dependency on soybean imports. Thereby such green biorefineries could contribute to the development of more self-sufficient and sustainable agricultural systems in Europe. The framework of this PhD study is a green biorefinery concept for the production of protein concentrate, biogas and fertilizer from organic and locally grown green crops like alfalfa, clover or grass. After the screw pressing of the fresh crops, lactic acid fermentation of the green juice with Lactobacillus salivarius BC 1001 was assessed as the key method for the recovery of proteins. A leaf protein...

Catch Crops in Organic Farming Systems without Livestock Husbandry - Model Simulations
Provedor de dados: Organic Eprints
Autores: Müller, Dr. Torsten; Magid, Dr. Jakob; Jensen, Dr. Lars Stoumann; Nielsen, Dr. Niels Erik; Thorup-Kristensen, Dr. Kristian.
During the last years, an increasing number of stockless farms in Europe converted to organic farming practice without re-establishing a livestock. Due to the lack of animal manure as a nutrient input, the relocation and the external input of nutrients is limited in those organic cropping systems. The introduction of a one-year green manure fallow in a 4-year crop rotation, including clover-grass mixtures as a green manure crop is the classical strategy to solve at least some of the problems related to the missing livestock. The development of new crop rotations, including an extended use of catch crops and annual green manure (legumes) may be another possibility avoiding the economical loss during the fallow year.   Modelling of the C and N turnover in...

The inclusion of diatomaceous earth in the diet of grazing ruminants and its effect on gastrointestinal parasite burdens
Provedor de dados: Organic Eprints
Autores: McLean, Barbara; Frost, David; Evans, Eifion; Clarke, Aldwyn; Griffiths, Bernard.
Two studies were carried out to assess the efficacy of diatomaceous earth as an alternative to anthelmintics in grazing ruminants.  Animals treated with anthelmintics and groups of untreated animals were included for comparison.  Cattle and sheep which received the diatomaceous earth supplement had low Faecal Egg Counts (FEC) for the duration of the experimental period, similar to animals in the anthelmintic groups.  Inclusion of diatomaceous earth in the diet of grazing ruminants may offer some benefits in controlling internal parasites.

Soil mechanical behaviour of sandy loams in a temperate climate: case studies on long-term effects of fertilization and crop rotation.
Provedor de dados: Organic Eprints
Autores: Munkholm, Lars J.; Schjønning, Per; Petersen, Carsten T.
Two case studies on Danish sandy loams investigated long-term effects of fertilization and crop rotation. Case Study 1 compared a diversely cropped organically farmed soil (DFG(1)) with a conventionally farmed soil predominantly growing annual crops (DFA), both receiving animal manure.  In Case Study 2, a diversely cropped organically managed soil DFG(2)) receiving animal manure was compared with an almost exclusively cereal cropped conventionally farmed soil receiving no animal manure (CCC). A multi-level experimental strategy was followed to compare integrating field methods with specialized laboratory methods. Ease of tillage was described in the field and characterized using a drop shatter field test and by measuring aggregate tensile strength. Fitness...

Fôring i økologisk mjølkeproduksjon − kort innføring
Provedor de dados: Organic Eprints
Autores: Strøm, Turid; Ebbesvik, Martha; Lindås, Anitra.
Tiltak for å skape et miljø som tilgodeser husdyras naturlige atferd står sentralt i økologisk husdyrhold. Fôringa skal i størst mulig grad bygge på gårdens egne ressurser. Beite og konservert grovfôr dyrket etter økologiske retningslinjer er de viktigste fôrmidlene  i mjølkeproduksjonen. I et økologisk driftsopplegg bør kyrne ha stor evne til å ta opp og omsette grovfôr. Fôrrasjonen bør være allsidig sammensatt med flere grovfôrslag. Kraftfôrforbruket er ofte lavere enn i konvensjonell mjølkeproduksjon. Dette medfører at en i økologisk mjølkeproduksjon tilstreber en flat mjølkekurve for å redusere toppytelsen. Da blir det lettere å dekke kuas energibehov i topplaktasjonen. De fleste som driver økologisk mjølkeproduksjon, har NRF-kyr, men det er også en...

Feed production on farms without animals is not environmentally sustainable
Provedor de dados: Organic Eprints
Autores: Steinshamn, Håvard; Bleken, Marina A; Thuen, Erling.
Use of high energy feed supplementation can improve the protein retention by the cattle, and it has been suggested as a way to increase the nitrogen (N) effi-ciency of dairy production. However, in praxis feed supplementation is also used to increase the intensity of animal production above the level that can be supported by the farm's local plant production.  A collection of published surveys showed that dairy farms that buy feed are considerably lees N efficient than farms that supply the entire animal ration from their own plant production. The total N emission to the environment per litre milk doubled when 30% of the total feed ration was produced outside the dairy farm. This was so for organic as well as conventional farms. Similar results can be...

Autores: Søegaard, Karen.
Med mindst 60% grovfoder i rationen og 100% økologisk foder er det vigtigt med en stor optagelse under afgræsning, hvilket for-udsætter et stort og godt tilbud af kløvergræs i marken. Udfordringen er både at opfylde det-te behov og samtidig at opnå en høj produkti-vitet i marken. Der er yderligere kommet en ny sædskiftemæssig udfordring, idet kløver-træthed er blevet et udbredt fænomen i de kløverrige sædskifter tæt på gården, hvor af-græsning foregår.    Flere forsøg har vist, at optagelsen øges med stigende tilbud (f.eks. Mayne &amp; Peyraud, 1996). En væsentlig grund hertil er, at køerne har mulighed for at optage mere pr. bid. Men det gælder kun til en vis grænse, da vraggræs med dårlig kvalitet efterhånden vil nedsætte udnyttelsen af kløvergræsset, og...

Korn indgår i alle delforsøgene som den ene behandling i sammenligning med tilskudsfodermidler, som bidrager med en større mængde protein, fedtsyrer eller cellevægge. I nogle forsøg er tilskudsfodermidlerne substitueret på grundlag af fylde, og i andre på grundlag af udbyttet på et givet areal. Proteinrige tilskudsfodermidler gav ved en grundration med højt stivelsesindhold og lav proteinværdi samme eller højere energikorrigerede mælkeydelse end byg.

Contribution of organic agriculture to macro-economic and environmental performance of the countries with economies in transition
Provedor de dados: Organic Eprints
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...

Organic poultry farming
Provedor de dados: Organic Eprints
Autores: Hermansen, John E.; Horsted, Klaus.
The development in organic livestock production can be attributed to an increased consumer inter-est in organic products while, at the same time, farmers are interested in converting to organic pro-duction methods – often stimulated by governmental support or subsidies. It is important that the organic production systems can fulfil the expectations of each of these stakeholders if the organic livestock production is to increase further. This is in particular important if the organic poultry pro-duction should move from the present niche-production to a real player in the food marked, like in the case of beef and milk.     It can be argued that the limited organic poultry production is related to the fact that it is far more difficult for the farmers to...

Practical recommendations    Observations and practical tips  • Pay attention to the soil structure when applying any mechanical operation. During the harvest, offloading should take place at the headlands.  • In the case of a high presence of deep-rooting weeds, choose a double-layer soil preparation (instead of compacting the soil) in order to increase porosity.  • Avoid sowing if heavy rains are expected in the next 5-6 days.  • Include cover crops in the rotation to improve soil structure. Cover crops are a key element to fine-tune direct drilling techniques.   • Directly drilled soil warms up more slowly in...

Comparación de la estructura y rendimientos ganaderos en sistemas de producción tradicional y ecológico de bovino en Extremadura. Comparison of the structure and livestock yields in traditional production systems and ecological bovine Extremadura
Provedor de dados: Organic Eprints
Autores: Rico, S; Escribano, B; Granes, JF; Escribano, AJ; Gaspar, p.
The paper analyzes the structure and performance of beef cattle farms in Extremadura: Conventional (n = 50), Organic with no sales of organic products (n = 37) and Organic farms with sales of organic products (n = 11).    Regarding stocking rate levels, no significant differences were observed among groups. By contrast, significant differences among the three types of farms regarding racial structure (p &lt;0.05). Similarly, significant differences were found (p &lt;0.1) in relation to farm's area, cattle's reproductive management and performance.    The study highlights the similarity between conventional and organic cattle production in Extremadura. This fact could allow a smooth transition of conventional farms to the organic production model.

Na presente revisão, buscou-se apresentar os principais impactos ambientais causados pela pecuária, sobretudo, em relação às emissões de gases efeito estufa (GEE). Além disso, buscou-se apresentar possíveis formas de mitigar essas externalidades. A criação de bovinos, no Brasil, acontece de forma extensiva, muitas vezes em áreas com pastagem degradada e, portanto, de baixa produtividade. Isso possibilita à atividade uma oportunidade de redução do impacto causado ao meio ambiente, uma vez que ações tomadas, no sentido de melhorar o rendimento animal, devem resultar em um menor consumo de recursos naturais (terra e água) e maior eficiência do sistema digestivo animal. Os principais problemas apontados pelos pesquisadores, no que tange à pecuária extensiva,...

Ingen forskel på nitratudvaskning
Provedor de dados: Organic Eprints
Autores: Berntsen, Jørgen.
Registerdata er blevet anvendt til modelberegninger med DJF’s bedriftsmodel FASSET. Beregningerne viste, at på et udsnit af typiske danske jorde var udvaskningen fra både økologiske og konventionelle planteavlere ca. 36 kg N/ha. Forskellen mellem økologisk og konventionel planteavl kom dog til udtryk i ændringer i organisk stof i jorden. Mens økologerne opbyggede ca. 13 kg N/ha om året, tærede de konventionelle ca. 6 kg N/ha om året på jordens organiske stof.      Modellen blev yderligere brugt til at gennemregne effekten af forskellig driftspraksis. Anvendelse af efterafgrøder var klart det mest effektive virkemiddel til at reducere kvælstofudvaskningen. I gennemsnit over et helt sædskifte blev udvaskningen således reduceret med ca. 9 kg N/ha. Det svarede...

Workshop and desk study to appraise technical difficulties associated with organic pullet rearing
Provedor de dados: Organic Eprints
Autores: Gordon, S.
Background  To date, Regulation (EC) 1804/1999 and UKROFS Standards allow conventionally reared pullets up to 18 weeks of age to be brought into systems of organic egg production.  Pullets must be reared according to the rules laid down in Regulation (EC) 1804/1999 and according to UKROFS Standards for at least six weeks, before the eggs may be sold as organic eggs.  The derogation for pullet rearing has been agreed for a transitional period expiring on 31 December 2003.  If pullets are to be reared from day old in an organic system in accordance with Regulation (EC) 1804/1999 and UKROFS Standards this may potentially create a number of technical problems, which may disadvantage UK producers considering organic egg production.  A series of workshops and a...

Minifundios and metropolis: territorial management of organic farming in Ibiúna (São Paulo, Brazil).
Provedor de dados: Organic Eprints
Autores: Abreu, Lucimar Santiago de; Bellon, Stéphane.
In spite of the growing demand in green vegetables from three main cities in São Paulo State, smallscale vegetable farmers are still facing economic problems. Subsequently, the maintenance of small farmers and families depending solely on agriculture appears as very difficult. Organic Farming (OF) is increasingly considered as a possible alternative for designing a "new rural" in Brazilian communities (Abreu, 2000). It is seen as an opportunity for economic valuation of horticulture products (root, fruit and leaf vegetables for salads). The existing demand for this type of product, together with favorable green market prices, especially during summertime, would both stimulate and propitiate an expansion in production (Assis, 2002). The consumer of organics...

The Danish case study on coexistence and seed production of forage and vegetable crops
Provedor de dados: Organic Eprints
Autores: Boelt, B.
Co-existence is defined as the farmers being able to choose between conventional, organic and genetically modified (GM) crop production, in compliance with the relevant legislation on labelling rules and purity standards.  Genes of cultivated plants spread in time and space through pollen and seed dispersal, and in addition handling during transport and processing may also disperse seeds.  The starting point in plant production is the seed. Consequently, suitable measures during cultivation, harvest, transport, storage, and processing are necessary to ensure co-existence in the supply chain of propagated seed.  In crops with restricted production area such as hybrid oilseed rape and vegetables, seed production in confinement may serve as an instrument of...

Effekten af økologiske driftsmetoder på ler-dispergering i kulstof-udpinte jorde
Provedor de dados: Organic Eprints
Autores: Schjønning, P.; de Jonge, L.W.; Olesen, J.E.; Greve, M.H.
Mange danske jorde – især på Øerne – har i dag et lavt indhold af organisk stof som følge af årtiers ensidige kornsædskifter og ringe brug af husdyrgødning. I denne artikel viser vi, at lerpartikler (kolloider) i jord med et lavt indhold af organisk stof frigøres til jordens vandfase (dispergering), hvilket efterfølgende kan have store påvirkninger af vigtige jordfunktioner. Økologiske driftsformer er generelt karakteriseret ved en stor tilbageførsel af organisk stof til jorden og kan derfor potentielt modvirke den omtalte lerdispergering.

This research indicates that it is possible for farmers to convert from an intensive conventional system (Punjab) to organic farming, or to make a living on a smallholding in difficult terrain (Uttarakhand). Both alternatives can provide a good livelihood with sustainable methods. I also found that the organizations that assist the farmers in this transition are crucial, because they teach the farmers new methods and give practical and moral support during a time when they feel uncertain making such a large change in how they make their living. One of them is Navdanya, which has been working in Uttarakhand and in several other states in India for nearly three decades.

Provedor de dados: Organic Eprints
Autores: Liu, Dibo; Pedersen, Lars-Flemming; Lazado, Carlo Cabacang; Strauss, David L.; Meinelt, Thomas.
Peracetic acid (PAA) can improve water quality in a way that does not affect the fish, the farmer nor the environment. This presentation included recent findings of ways to improve PAA water treatment strategies. The study compared two distinct way of applying PAA – either as a pulse or as low dose continuous addition. Selected markers to address potential negative impact on fish welfare were used.  Cortisol expression was temporarily increased following pulse addition but subsequently fish adapted and cortisole expression remained at low, similar levels as measured among control fish and fish exposed to continuous low dose PAA exposure. Pros and cons about PAA application and its consequences were discussed as well.

Økologisk mælkeproduktion. Fodring og management ved høj selvforsyning
Provedor de dados: Organic Eprints
Autores: Kristenseen, Troels.
Overgangen til fodring udelukkende med økologisk foder ses som en væsentlig udfordring, specielt i kombination med at de økologiske principper understøtter at foderet produceres på bedriften.   I fremtidens økologiske mælkeproduktionssystemer forventes derfor øget fokus på selvforsyning med foder. Foderrationen forventes i stigende grad at være baseret på grovfoder, idet udbytte-potentialet under danske dyrkningsbetingelser er klart højest i de typiske grovfoderafgrøder (græs, majs og helsæd) i forhold til mere proteinrige og koncentrerede afgrøder som ærter, lupiner og korn til modenhed. Der er imidlertid behov for mere viden om den mest hensigtsmæssige tilpasning af bedriften således, at en høj selvforsyning med foder, kan ske samtidig med at bedriften...

Catch Crops in Organic Farming Systems without Livestock Husbandry - Simulations with the DAISY model
Provedor de dados: Organic Eprints
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...

Zur Notwendigkeit agrarstruktureller Veränderungen [Necessities for changes in livestock production]
Provedor de dados: Organic Eprints
Autores: Sundrum, Albert.
Das Vertrauensverhältnis zwischen Verbrauchern und Erzeugern tierischer Produkte ist gestört. Durch zurückliegende Skandalmeldungen, aber insbesondere durch die ersten BSE-Fälle in Deutschland, wurde einer breiten Bevölkerungsschicht bewusst, dass die Erzeugung von Lebensmitteln tierischen Ursprungs in vielen Aspekten nicht mit ihren Vorstellungen von Landwirtschaft übereinstimmt. Den Vertrauensverlust allein dem Fehlverhalten Einzelner oder einzelner Berufsgruppen anzulasten, wird den komplexen Strukturen der Erzeugung, des Handels und der Vermarktung sowie der Mitverantwortung der Verbraucher nicht gerecht.   In der tierischen Erzeugung führt die mit der Intensivierung einhergehende Überproduktion unabhängig von der Betriebsgröße seit Jahren zu einem...

Organic clover seed production: Does intercropping with plant species with at strong scent distract the clover seed weevil and increase seed yield?
Provedor de dados: Organic Eprints
Autores: Hansen, Lars Monrad; Boelt, Birte.
A field experiment was conducted in 1999-2001 in order to test if intercropping with other plant species with at strong scent would be able to distract clover seed weevils away from the clover seed field. Intercropping with chives, caraway, oregano or thyme did not have any effect on the number of clover seed weevils registered and white clover seed yield was not affected by any of the treatments. It is concluded, that a well-established white clover seed crop is very competitive against other plant species.

Group suckling in organic sow units
Provedor de dados: Organic Eprints
Autores: Früh, B; Hagmueller, W; Aubel, E; Simantke, C; Schwarz, P; Baumgartner, J.
Group suckling - a combined system of single and group housing of lactating sows - appears a suitable system for organic pig production. The aim of the study was to describe the status quo of group suckling in organic farms. 31 organic sow units in Germany, Austria and Switzerland were investigated. Stockmen were interviewed, stables were inspected and animals were examined during three visits on each farm enterprise, respectively. The majority of farms kept three sows with piglets in one group suckling unit. 76 % of the group suckling sows (n=192) were in a good nutritional condition, 18 % were considered thin and 8 % of sows were too fat. Relatively few sows showed skin lesions caused by poor housing conditions. Only 18 of 203 sows behaved anxiously or...

Learning in context – improved nutrient management in arable cropping systems through participatory research
Provedor de dados: Organic Eprints
Autores: Wivstad, Maria; Naetterlund, Henrik.
Participatory research (PR) provides opportunities to build knowledge relevant to site-specific farms conditions. This study used a PR approach to develop nutrient management strategies in stockless organic farming. A thorough problem identification process was carried out and the problem prioritised was how to combine preceding crop effects with fertilisation strategy in crop rotations. On-farm fertiliser (biogas digestion residues, chicken manure and meat-bone meal) experiments were conducted in spring wheat and winter rapeseed. Significant yield responses were achieved in spring wheat, up to 1200 kg ha-1, and they were higher than in rapeseed. The implications of the results for nutrient management at crop rotation level are discussed.

Frugt og bær trives godt på øerne. En vigtig årsag til dette er at nattefrost i maj kan tage pynten fuldstændigt af frugt- og bærudbytter, men den kolde oplevelse er sjælden, når man er omgivet af lunkent vand, som øboere jo er. Frugt og bær giver også trivsel til dem, der spiser dem. Indholdet af sundhedsfremmende stoffer er i frugt og bær større end i nogen anden landbrugsafgrøde, så det er produkter, vi burde spise flere af.

Effect of seed rate and row spacing in seed production of Festulolium
Provedor de dados: Organic Eprints
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...

Co-existence with GMOs and organic seed production
Provedor de dados: Organic Eprints
Autores: Boelt, B.
Co-existence is defined as the farmers being able to choose between conventional, organic and genetically modified (GM) crop production, in compliance with the relevant legislation on labelling rules and purity standards.  Genes of cultivated plants spread in time and space through pollen and seed dispersal, and in addition handling during transport and processing may also disperse seeds.   Consequently, suitable measures during cultivation, harvest, transport, storage, and processing are necessary to ensure co-existence in the supply chain of propagated seed. With the increasing area of GM-crop production as well as in the number of crops in which GM-varieties are available the need for guidelines to ensure coexistence are becoming increasingly essential....

Organic farming is increasingly being taken up by farmers and agricultural development agencies in tropics. This is in a bid to improve world food security and rural livelihoods in a sustainable way. Long-term field trial that compares organic and conventional systems was set up in sub-humid central Kenya since 2006 to provide a scientific basis for organic agriculture in the region. The project seeks to gather data on how organic farming affects: yield and yield stability; stability of the agro-ecological system; and natural and economic resource efficiency. The experiments were set up at two sites namely Chuka and Thika. Both sites are at an altitude of 1500m asl. While Chuka lies in a high potential area with 2000 mm of rainfall and good soil phosphorus...

GM organisms threaten organic systems: towards sustainability, coexistence and organic seed
Provedor de dados: Organic Eprints
Autores: Boelt, B.; Deleuran, L.C.; Phelps, B.
Until now commercial genetically modified (GM) crops – soy, corn, canola and cotton - and their products have not been successfully segregated from organic or conventional non-GM production systems. Where GM crops are grown, GM contamination may be inevitable. However, physical and legal control measures imposed before the introduction of GM crops may help protect organic standards, supply chain integrity, certification and client confidence, but this is not yet fully tested. IFOAM’s approach to its present position on GM crops may not be sustainable long term as several invasive technologies – GM organisms (especially pharma crops, animals and micro-organisms), nanoparticles, and food irradiation – all challenge organic standards and integrity

A systems approach to the management of arbuscular mycorrhiza: Bioassay and study of the impact of phosphorus supply
Provedor de dados: Organic Eprints
Autores: Kahiluoto, Helena.
The aim of this study was to find out whether utilization of arbuscular mycorrhiza (AM), in crop production in Nordic conditions, can be promoted through management of the cropping system. P fertilization was chosen as the pilot system to manage because it has a major effect on AM and because it is problematic from the viewpoint of sustainability. Our scant knowledge of AM functioning and its effects in the field is mainly due to the methodological problems of research. Therefore, a bioassay of AM effectiviness was developed. In addition, the work demonstrated the challenge of a systems approach to research on low organizational levels of the agroecosystem. The starting point was the goal of sustainable phosphorus management in the food system, focused...

Agricultura em zonas ripárias do sul do Brasil: conflitos de uso da terra e impactos nos recursos hídricos.
Provedor de dados: Organic Eprints
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.

Er kamme et alternativ til pløjning?
Provedor de dados: Organic Eprints
Autores: Bugge Henriksen, Christian.
På Landbohøskolen arbejder vi med et alternativt jordbearbejdningssystem, hvor man i stedet for at pløje hypper jorden op i kamme om efteråret. Opsætning af kamme hvor det øverste jordlag lægges ind i kammen er en langt mere skånsom jordbehandling end pløjning hvor jorden vendes rundt. I forhold til andre former for pløjefri dyrkning har kamme den umiddelbare fordel, at de giver bedre mulighed for at indarbejde husdyrgødning og afgrøderester i jorden, ligesom de giver bedre mulighed for at bekæmpe ukrudtet mekanisk. Vores foreløbige resultater viser desuden at kamme rummer muligheder for at reducere udvaskningen af kvælstof og øge omsætningen af organisk stof.  I det nystartede projekt (CARMINA) undersøger vi mulighederne for at få dyrknings-systemer med...

Zielvorstellungen und Entwicklungsperspektiven für den Ökolandbau aus Naturschutzsicht
Provedor de dados: Organic Eprints
Autores: Oppermann, Rainer; Hoetker, Hermann; Schoene, Florian.
Der Ökolandbau wirtschaftet in der Regel deutlich naturnäher als der konventionelle und integrierte Landbau und kommt somit auch den Naturschutzzielen am nächsten. Dies ist mehrfach durch Untersuchungen belegt, jedoch oftmals nur für einzelne Artengruppen (Pflanzen, Insekten) und Einzelflächen, nicht aber für ganze Landschaften und die Avifauna der Landschaften. Mit dem derzeitigen starken Wachstum der Biobetriebe ist auch eine starke Zunahme der Intensiv-Biobetriebe verknüpft, die z.B. im Grünland oftmals genauso intensiv bzw. wenig naturnah wirtschaften wie konventionelle Vergleichsbetriebe. Dies hat Auswirkungen auf die Ökosysteme und die Fauna der Landschaften.    In dem Vorhaben sollen nun zum einen mit Literaturrecherchen und Expertenbefragungen die...

Status Quo der Ökologischen Bienenhaltung in Deutschland
Provedor de dados: Organic Eprints
Autores: Anspach, Dipl.-Ing.agr. Victor; Herrmann, Dipl.-Ing. Jonas; Möller, Prof. Dr. Detlev.
There is currently an estimated 320 organic beekeepers in Germany. Until recently,  there has been no scientific research conducted on the status of the sector. For this  reason, an empirical study was designed to analyse the structure and specifics of  organic beekeeping. 150 beekeepers are practicing apiculture as their main branch of  production and keeping more than 25 bee hives. This corresponds to 3.3% of all  professional beekeepers in Germany. The number of organic beekeepers and hives is  on the rise, with many beekeepers seeing a great potential in the organic honey market.  Of those practicing organic apiculture, 50% are planning to increase production  over the next 3 years.

Autores: Schrade, Sabine; Keck, Margret; Schick, Matthias.
There was a lack of up-to-date statistics on the working time requirements in suckler  cattle farming under Swiss production conditions. A combination of final and causal  methods for recording working time was used to determine working-time input and  working-time requirements, to survey influence variables and draw up working-time  models using a model calculation system. The total working time spent on suckler  cattle farming varied between 28 and 120 hours per cow per year, with an average of  66 hours per cow per year. Over half of this time was spent on routine work, 20 % on  management work, 19 % on other non-daily work and 3 % on direct marketing, animal  care and animal handling, respectively. The larger the herd size, the lower the time  spent on...

Plantedække øger udnyttelsen af N i økologiske grønsager
Provedor de dados: Organic Eprints
Autores: Thorup-Kristensen, Kristian.
I artiklen præcenteres resultater og erfaringer fra 8 års forsøg med økologisk grønsagssædskifte ved Danmarks JordbrugsForskning i Årslev. En af de centrale resultater er at det har meget stor effekt at holde markerne grønne i efteråret. Selvom der har ingået mange forskellige typer efterårsdække, fra helårsgrøngødning, til efterafgrøder med og uden bælgplanter og endda kålstub der har fået lov at gro videre efter at kålhovederne er høstet, så har det grundlæggende haft den samme effekt. Med plantedække i efteråret efterlades der langt mindre N i jorden som kan udvaskes, men om foråret mineraliseres der væsentligt mere N i jorden som kan udnyttes af den følgende afgrøde. Grøngødning giver naturligvis større mineralisering end f.eks. kålstub, men den...

Organic pig production – With particular reference to Danish production conditions
Provedor de dados: Organic Eprints
Autores: Kongsted, Anne Grete; Hermansen, John E.
While there is a markedly growth in organically farmed land and in the organic food sector as such in Europe and North America, the organic pig sector has not developed correspondingly in most countries. This weaker development seems most likely to be due to difficulties for pig producers to comply with the organic standards, which impose comparatively more pronounced changes in the way of production than e.g. in ruminant production systems. Pigs should have access to roughage and to grazing in the summer period although finishers can be kept in barns if access to an outdoor rum. A common way to comply with these regulations is to have sows on grassland all year round, but to rear the finishers in stables. Outdoor piglet production can be very efficient...

Integrated forage and livestock production
Provedor de dados: Organic Eprints
Autores: Hermansen, John E.; Kristensen, Troels.
Integrated forage and livestock production can be considered at the farm level and at the herd or animal level. At the farm level it is relevant to consider the overall utilization of N in the system in relation to crops and livestock. It is demonstrated that in organic dairy production a high transformation efficiency of N from input to edible products can be achieved compared, with conventional production. In addition, combining dairy and pig production allows an even higher N utilization. At the herd level the quality of grass or clover-grass based forage is extremely important. This holds for the overall intake and milk production in dairy cows and for the intake of clover-grass by grazing sows. In addition the composition of the sward should be...

This article explores the possibilities for rethinking agricultural research for development (R4D) in the light of new challenges characterized by a high degree of scientific uncertainty along with associated intense political differences of interest. New challenges that particularly influence food production in underprivileged regions include global climate change, globalization of food chains, and emerging low-carbon energy systems. We argue that by applying the people-centered sustainable livelihoods approach as a research paradigm in R4D, researchers may be more successful in producing knowledge that is useful to...

A Agroecologia como um campo científico.
Provedor de dados: Organic Eprints
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.

Evaluation and design of multispecies cropping systems with perennials: are current methods applicable?
Provedor de dados: Organic Eprints
Autores: Rapidel, Bruno; Meziere, Delphine; Metral, Raphaël; Dupraz, Christian; Mérot, A; Allinne, Clémentine; Gary, Christian.
The existing methods are applicable to multispecies cropping systems with perennials. However, the particular features of these cropping systems highlight the drawbacks of each of them. Therefore, combining these approaches, where and when it is possible, should be preferred. Whatever the method, evaluation of the new systems requires new indicators development, to account for the multiple productions with very different timescales and serving varying objectives. Development of simple and effective sets of indicators adapted to these systems is a powerful tool to boost the design realm, for practitioners and researchers alike.

Genetics and welfare in organic poultry production. Genetics and welfare in organic poultry production  A discussion on the suitability of available breeds and hybrids
Provedor de dados: Organic Eprints
Autores: Brunberg, Emma; Grøva, Lise; Serikstad, Grete Lene.
Organic production of eggs, broilers and turkey is regulated by international and national regulations and differs from conventional production. Breeds and hybrids selected for conventional production are also used in organic production. Many traits that are important for animal welfare are affected both by environment and genetics. This report gives an overview of the research about how animals with different genetics can be more or less suitable for alternative production systems. Moreover, the answers from a questionnaire among Norwegian poultry producers are reported. Possibilities for the development of animals more suitable for the goals and regulations in organic production are discussed.

The concept of the Danish working group on coexistence
Provedor de dados: Organic Eprints
Autores: Boelt, B.
In the spring of 2002, the Danish Minister for Food, Agriculture and Fisheries initiated  strategy work on the cultivation of authorised GM crops in Danish agriculture. The aim  was to produce a Danish model for the co-existence of GM, conventional and organic  crops in support of the free choice of consumers and to ensure development possibilities  for new and existing agricultural production forms. Three groups were set up, that were  assigned the task of presenting the scientific and legal problems as well as drawing up a  proposal for a Danish co-existence model. These groups were the analysis group  (working group), the legal group and the contact group.

Rangering og udvælgelse af avlsdyr afhængig af produktionssystemet
Provedor de dados: Organic Eprints
Autores: Madsen, Per; Villumsen, Trine.
Tidligere eksperimentelle undersøgelser har vist at en øget anvendelse af grovfoder kan give anledning til en forskellig  rangering af genotyper indenfor en race, dvs. at udvælgelsen af de bedste avlsdyr vil afhænge af i hvilket produktionssystem køerne skal producere. Derfor er der gennemført analyser af data fra kvægdatabasen til afklaring af om der er forskel i den indbyrdes rangering af avlsværdi for mælkeydelse, sundhed og reproduktion afhængig af om køerne står i økologiske eller konventionelle besætninger. Undersøgelsen viste ingen forskel i rangering af avlstyrene afhængig af produktionssystem, men det kan ikke udelukkes at en yderlig forskel i fodring mv. mellem de to systemer vil ændre på resultatet.

Entraves para a certificação orgânica do leite numa central cooperativa de agricultores familiares do oeste catarinense.
Provedor de dados: Organic Eprints
Autores: Frison, Edilza; Rover, Oscar José.
O artigo analisa entraves para a transição agroecológica e adequação às normas de certificação orgânica, em unidades familiares produtoras de leite, a partir do caso de uma central de cooperativas de agricultores familiares, a qual possui 73 propriedades em transição. Os principais entraves identificados derivam da ausência de alternativa para venda do leite orgânico, do desconhecimento dos agricultores sobre normas e técnicas específicas para a produção orgânica, e da falta de apoio técnico e organizacional para geração de alternativas que seriam difíceis de implementar à escala de uma só unidade produtiva. Conclui-se que a precariedade da transição agroecológica colocaria os agricultores em risco, caso se aplicasse com rigor a legislação para a produção...

Organic farming effects on clay dispersion in carbon-exhausted soils
Provedor de dados: Organic Eprints
Autores: Schjønning, P.; de Jonge, L.W.; Olesen, J.E.; Greve, M.H.
Many Danish soils are depleted in organic matter (OM) after decades of intensive cereal cultivation (Schjønning et al., 2009). In this paper we show that clay particles (colloids) in soils that are low in OM content are easily dispersed in the soil water, which in turn has important effects on soil ecosystem functions and services. Organic farming systems generally tend to increase soil OM contents and may thus mitigate the negative effects.

How far can cycles be closed in organic dairy farming?
Provedor de dados: Organic Eprints
Autores: Iepema, ir G; de Wit, ir J.
Abstract - Dutch organic dairy farmers asked for a tool to get insight in the ecological sustainabilty of their farms. For that purpose, the area used for milk production outside the farm was calculated for 17 farmers. As expected, a high variation in external input was found, since diversity in farming was one of the selection criteria for involving the project.   Management factors as selling manure and crop rotation resulted in a smaller total area used per kg produced milk. A deep litter stable and a low clover percentage in the grassland fields caused on the other hand an increasment in total area used per kg milk and thereby a lower degree of closeness of nutrient cycles. The calculation of external hectares (ha) gave the farmers insight in the total...

Introduktion - perspektiver ved 100 pct. økologisk fodring
Provedor de dados: Organic Eprints
Autores: Kristensen, Troels; Sehested, Jakob.
I kapitlet skitseres den økologiske mælkeproduktion i Danmark samt de gældende og kommende rammer herfor. Desuden diskuteres perspektiverne i en økologisk mælkeproduktion baseret på 100% økologisk foder. Mælkeproduktionens omfang er gennem en kraftig vækst nået op på ca. 10% af den indvejede mælk i 2000. Markedet ser på kort sigt ud til at nærme sig en mætning, hvilket afspejler sig i en faldende merpris til producenten. Der identificeres to overordnede tendenser i udviklingen af produktionen inden for rammerne af 100% økologisk fodring: Den ene med en fastholdelse af de nuværende mål omkring produktionsniveau mv. per dyr, opnået ved en tilpasning af grovfoderkvalitet og økologisk dyrket tilskudsfoder. Den anden trend med en drejning mod en mælkeproduktion...

Bedding hygiene, cleanliness and lying behaviour  for heifers housed on wood chip or straw deep  bedding
Provedor de dados: Organic Eprints
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,...

A construção do discurso agroecológico no Movimento dos Trabalhadores Rurais Sem-Terra (MST).
Provedor de dados: Organic Eprints
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...

Effetto dei suoli degradati sul comportamento vegeto-produttivo della vite
Provedor de dados: Organic Eprints
Autores: Zombardo, A.; Puccioni, S.; Perria, R.; Leprini, M.; Priori, S.; Costantini, E.A.C.; Storchi, Paolo.
In Italian vineyards it is common to find  more or less extended areas with chemico-physical or  biological soil deficiencies and problems in plant vigor  and grape production. A reduced agronomic functionality  is caused by wrong soil managements and  improper land preparation before vine plantations. A  strong land transformation alters, in fact, the existing  natural balance, causing loss of organic matter and  nutrients, erosions, reduction of available water and  metal accumulation. This phenomenon affects the  growth of vines and the grape yields. The aim of this  work is to evaluate the effect of degraded soils on the  vineyards of two Tuscan vine-growing regions  (Chianti Classico and Maremma Toscana). In two  farms, we have identified respectively...

Prolonged suckling period in organic piglet production – Effects on some performance and health aspects
Provedor de dados: Organic Eprints
Autores: Bussemas, R.; Weissmann, F.
The organic piglet suckling period typically takes about 6 weeks due to the minimum requirement of the EEC Regulation 2092/91 of 40 days. But piglets weaned in such a period are often characterized by inferior performance and health status. It is the aim of the present study to examine whether a prolonged suckling period of 63 days results in better performance and health status of the piglets. Therefore 36 sows were divided into 2 groups of 18 sows each as a control group with 42 days suckling period and a test group with 63 days suckling period. The rearing period for both the control group and the test group ended on day 77 p.n., which was also the end of the piglets´ data collection period. Three farrowing cycles with 108 litters were recorded. The...

Organic carrot seed production in tunnels
Provedor de dados: Organic Eprints
Autores: Deleuran, L.C.; Boelt, B.
Aiming at developing ways to produce organic GMO-free seeds, trials on different vegetable species were conducted in lightweight tunnels. Organic vegetable seed production is possible in Denmark for some of the late maturing vegetable species - when performed in tunnels. At the Danish Institute of Agricultural Sciences (DIAS) different growing systems in tunnel have been studied in both open pollinated and hybrid carrot (Daucus carota L.) for seed production.  Tunnel production of carrot increases yield and germination percentages compared to normal field conditions and yields in the range of 100 –250 g seeds/m2 can be obtained.    The lightweight tunnel production system can be widely used and modified for small-scale producers also in developing countries.

Effect of topdressing on individual leaf photosynthesis at different position in direct-sown rice with non-woven fabric mulch system
Provedor de dados: Organic Eprints
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...

Provedor de dados: Organic Eprints
Autores: Theodoro, Vanessa Cristina de Almeida; Carvalho, Janice Guedes de; Corrêa, João Batista; Guimarães, Rubens José.
A produção de café orgânico vem se constituindo uma tendência necessária e irreversível do agronegócio brasileiro. Essa atividade tem-se destacado como uma alternativa de renda para alguns cafeicultores, devido à crescente demanda mundial por alimentos mais saudáveis. Entretanto, grande parte das técnicas propostas pela agricultura orgânica está sendo aplicada empiricamente no cultivo de café, principalmente no Estado de Minas Gerais, maior região produtora de café do Brasil. Levando-se em consideração a baixa fertilidade natural dos solos dessa região cafeeira, bem como a elevada extração de nutrientes pelo cafeeiro, objetivou-se neste trabalho identificar possíveis fatores limitantes para a produção orgânica do cafeeiro, relacionados à fertilidade do...

Provedor de dados: Organic Eprints
Autores: Jokumsen, Alfred; Lembo, Giuseppe.
Feed costs account for more than half of the production costs in aquaculture. In particular this concerns organic aquaculture, which has to comply with specific rules for sourcing feed ingredients for organic feed. Thus, specific rules on feeds for carnivorous aquaculture animals request that the feed shall be sourced with the following priorities (EU Reg. 710/2009 art. 25k, as amended by EU Reg. 1358/2014): (a) organic feed products of aquaculture origin; (b) fish meal and fish oil from organic aquaculture trimmings; (c) fish meal and fish oil and ingredients of fish origin derived from trimmings of fish already caught for human consumption in sustainable fisheries; (d) organic feed materials of plant origin and of animal origin;  (e) feed products...

Links between profitability, nitrogen surplus, greenhouse gas emissions, and energy intensity on organic and conventional dairy farms
Provedor de dados: Organic Eprints
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...

The prevention of potato volunteers in organic farming systems by using pigs.
Provedor de dados: Organic Eprints
Autores: Hospers-Brands, A.J.T.M.; Bremer, E.G.H.; Lammerts van Bueren, E.T.
In organic agriculture potato volunteers, presenting an important primary inoculum source for late Blight (Phytophthora infestans), are controlled by mechanical meth-ods. These may be partly replaced by ‘foraging’ livestock animals, such as cattle, sheep, horses, ponies or pigs. Most animals eat only the remaining potatoes on the field surface; however, pigs also dig up potatoes. This paper reports on two experi-ments with pigs (sows or finishing pigs), which appear to be very effective in digging up potatoes that are left in the field after the potato harvest within a reasonable time period. However, the workload for the farmer, problems with animal health and meat quality and possible damage to the soil structure seriously limit the applicability of pigs...

Autores: Costantini, E.A.C.
Il suolo, definito dall’Unione europea come la parte più esterna della crosta terrestre, situata tra la roccia o il sedimento inalterato e l’atmosfera, è un sistema naturale complesso, multi-fase, che tende ad auto-organizzarsi in conseguenza dell’azione dei fattori della pedogenesi e in particolare dell’attività biologica, che ne determina i maggiori dinamismi. Non è quindi un mero substrato inerte, statico, attraverso il quale realizzare le produzioni agricole e forestali o sul quale appoggiare le nostre attività e infrastrutture, ma un essere vivente. Il suolo è un patrimonio naturale che si è formato in prevalenza nei millenni precedenti l’Antropocene, l'era geologica attuale, nella quale l'essere umano e le sue attività causano le principali modifiche...

Improvement of calculation methods for net grassland production under different grassland utilization systems
Provedor de dados: Organic Eprints
Autores: van de Goor, Stijn.
Throughout Europe, grass is major source of nutrition for ruminants. Grass can be grazed, fed fresh, as silage or as hay or in a preserved form as silage or hay. Over the past years summerfeeding has increased at the cost of grazing in dairy herds. One important reason for farmers to house their animals is optimization of grassland utilization. Investigations show than summerfeeding has higher yields than grazing, but is this also the case with net production. This study researched energetic calculation methods for the determination of net grassland production. The energy systems evaluated are the methods of Lantinga, Leisen and the KringloopWijzer (KW). The objective of this paper is to analyse, compare and check the reliability of these energy...

The effect of timing of ridging on soil inorganic nitrogen and potato tuber yield and quality
Provedor de dados: Organic Eprints
Autores: Henriksen, Christian Bugge; Rasmussen, Jesper; Mølgaard, Jens Peter.
Field experiments were conducted on sand and sandy loam from 2000-2002 to determine how timing of ridging affects potato tuber yield and quality depending on soil type and the use of catch crops. On sand, ridging in winter increased nitrogen availability in the 0-50 cm soil layer in spring by 19% from 5.7 to 6.8 mg N/kg soil compared with ridging in autumn (P&lt;0.001) and by 8% from 6.3 to 6.8 mg N/kg soil compared with ploughing in spring (P&lt;0.05). With a total and marketable yield of 27,9 t/ha and 14,2 t/ha respectively, ridging in winter resulted in higher tuber yield than both ridging in autumn and ridging in autumn combined with tilting and re-establishment of ridges in winter. These yield results were comparable to spring ploughing, but because...

Helminth parasites in pigs: challenges and current research highlights
Provedor de dados: Organic Eprints
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...

INTRODUCTION: The Ibores-Villuercas region (located in SW Spain)  is known for its dairy goat farms producing cheeses of high quality (P.D.O. Queso Ibores).  The present study characterizes such farms and assess their sustainability, as a tool to determine which farms present more feasibility to carry out a conversion to the organic system. This conversion could be used as a marketing tool for these farms, and contribute to local  development (both economically and socially), ensuring the maintenance of the farms and rural population while enabling the preservation of valuable landscapes.    METHODOLOGY: farms where classified using cluster analysis. Later, a sustainability assessment of the clusters (groups of farms) was carried out. Finally, farms'...

Autores: Johanssen, Juni Rosann E.; Sørheim, Kristin; Brunberg, Emma; Strøm, Turid.
Denne rapporten omhandler den ene delen av et todelt prosjekt gjennomført av Norsk senter for økologisk landbruk. Formålet med denne delen av prosjektet var å finne ut om bruk av flis til dypstrø kan gi like god dyrevelferd som bruk av halm, og om det er forskjell på kostnader og arbeidsmengde. Det ble gjennomført et forsøk med to binger med ungdyr (kviger) på Tingvoll gard fra 11.1. til 4.4.2016, hvor dypstrø av flis og halm ble sammenlignet. Vi undersøkte dyras liggeatferd, renhet og forekomst av parasitter i dyras avføring. Strøet og dypstrøet ble undersøkt for innhold av mikroorganismer. Resultatene fra forsøket viste at dyra hadde signifikant lengre liggetid på halm enn flis. Det var ikke signifikant forskjell på antall liggeperioder eller tid per...

Biologische Helminthenkontrolle bei Weidetieren mit nematophagen Pilzen
Provedor de dados: Organic Eprints
Autores: Hertzberg, Hubertus.
Aufgrund ihrer weiten Verbreitung und der erheblichen Pathogenität einiger Spezies stellen gastrointestinale Nematoden bei Weidetieren ein Gesundheitsrisiko dar. Die Kontrolle dieser Parasiten basiert seit mehreren Jahrzehnten nahezu ausschliesslich auf dem Einsatz von Entwurmungsmitteln (Anthelminthika). Diese Tatsache hat speziell bei den Magen-Darm-Nematoden (MDN) der kleinen Wiederkäuer und bei den kleinen Strongyliden des Pferdes weltweit zu einer erheblichen Resistenzentwicklung geführt, von denen im Falle der ovinen MDN sämtliche kommerziell verfügbaren Anthelminthika-Klassen betroffen sind. Da sich praxisreife Alternativstrategien für die Parasitenbekämpfung bisher nicht ausreichend etablieren konnten, führt die verschärfte Resistenzlage zu einem...

Simulating crop production and nitrate leaching losses from organic arable crop production
Provedor de dados: Organic Eprints
Autores: Olesen, J.E.; Berntsen, J.
Crop models can be powerful tools to analyse the effect of changes in management of cropping systems on productivity and environmental impact, provided the models have been thoroughly tested. The FASSET model was found to adequately reproduce effects of management (manure and catch crops) and of site (soil and climate) on crop yields and nitrate leaching from a 4- crop rotation with a grass-clover green manure crop in one out of four years. Scenario analyses shown that the nitrate leaching increased relatively more with increasing N fixation in the grass-clover than did the crop yields. The yields could be increased and the nitrate leaching reduced by using catch crops and/or using the grass-clover for biogas instead of a green manure, assuming that the...

Es wird der Einfluss von Stroh- und Gründüngung auf den Ertrag und die Qualität von Öko-Hafer untersucht. 3-jährige Feldversuche zeigen, dass Strohdüngung einen leichten Ertragsrückgang bei Hafer zur Folge hat. Gründüngung dagegen führt sowohl mit Leguminosen als auch mit Gras zu deutlichen Mehrerträgen.  Im zweiten Beitrag (K. Bauer &amp; U. Jäckel) werden 10 Jahre Ökolandbau im Lehr- und Versuchsgut Köllitsch in Sachsen ausgewertet. Dabei zeigt sich, dass trotz negativer Nährstoffbilanzen für N, P, K und Mg lediglich bei K eine Unterversorgung...

Annual self-reseeding legumes and their application into mediterranean cropping systems.
Provedor de dados: Organic Eprints
Autores: Driouech, Noureddin.
Soil fertility management is a major concern in organic farming. According to the EEC Regulation 2092/91, soil fertility must be maintained and/or increased by legumes cultivation. Native Mediterranean legumes ecotypes are more persistent than commercial varieties but their use in catch crop sequences is still limited. The N2-fixing legumes crops as a local resource can be considered as an alternative to improve nitrogen nutrition and to increase crop yields. This study aimed to investigate the agronomic performance of seven annual self-reseeding legumes and the short–term effect of nitrogen supply on the subsequent crops. Results are presented from field experiment on sandy-clay soil, pH 8.1 and 1.6% of organic matter, in the south of Italy, where the...

Linking water treatment practices and fish welfare
Provedor de dados: Organic Eprints
Autores: Zubiaurre, Claire; Pedersen, Lars-Flemming.
Peracetic acids can be used as sanitizers to control water quality in aquaculture systems. As an alternative to formalin, chloramine-T or copper sulphate, PAA has strong anti-microbial effects, degrades quickly and is relatively safe to use. Its mode of action and associated rapid decay can make optimizing treatment protocols a challenge. Continuous low-dose applications seem to be a promising solution. In this  preliminary study behavioral response was used to assess potential correlations with PAA dosage. A behavioral change or response is not necessarily an indication of compromised welfare.   Supportive enzymatic, biochemical and physiological biomarkers can be used along with gill  and epidermal histological measures to evaluate the effects on water...

SUMMER chickens "on herbs"
Provedor de dados: Organic Eprints
Autores: Steenfeldt, S.; Horsted, K.
In the organic RDD project ’SUMMER’, an experiment with organic broilers with access to a large range area with herbs has been performed. The effect of chicken genotypes with different growth rates and different feeding strategies on the animals’ feed intake, growth, welfare, health and meat quality was investigated.  The results so far indicate that it is necessary to use chicken genotypes with lower growth rates for a better welfare, and the focus should be on the individual genotype and its actual nutrient requirements and utilisation of feed from the range area.

Forage based low-input dairy systems include a certain risk of a temporary undersupply with nutrients and energy. Therefore the aim of the present study was to investigate the productive, reproductive and metabolic response of two different dairy cow types to a reduction of concentrate supplementation in an Alpine low-input milk production system. The cow types compared were conventional Austrian Brown Swiss (BS) and a specific strain of Holstein Friesian (HFL). The latter was primarily selected for lifetime performance and Fitness under low-input conditions and is therefore considered by Farmers as being better suited for low-input production systems. Both genotypes were assigned to one of two concentrate supplementation levels, receiving 618 kg (Con) or...

Separasjon av ku og kalv - Atferd hos ku og kalv i melkeproduksjon etter separasjon ved to ulike metoder
Provedor de dados: Organic Eprints
Autores: Johanssen, Juni Rosann E.; Brunberg, Emma; Sørheim, Kristin.
I konvensjonell melkeproduksjon er det ingen krav om at ku og kalv skal være sammen, og tradisjonelt blir ku og kalv separert umiddelbart eller kort tid etter fødsel. I økologisk melkeproduksjon skal kalven die kua i minst tre dager, og den skal ha naturlig melk i minst tre måneder. Forbrukerne er stadig mer opptatt av dyrevelferd, og det er et økende fokus på det å ha ku og kalv sammen lenger i melkeproduksjon. Det er mange fordeler med å ha ku og kalv sammen lenger, men det er også utfordringer. En av utfordringene er at dyra kan vise en sterkere stressrespons etter separasjon sammenlignet med om man separerer de raskt etter fødsel. Det finnes ulike metoder for brå og trinnvis separasjon av ku og kalv, og forskning viser at noen metoder kan gi mindre...

Using Green Biorefinery Technology to Enhance Domestic Self-Sufficiency in Protein Feed Supply – Economic Impacts on Conventional and Organic Farming
Provedor de dados: Organic Eprints
Autores: Jensen, Jørgen Dejgaard; Gylling, M.
This paper examines the sector economic consequences of protein extraction for non-ruminant feeding from grass, using green biorefinery conversion technology to increase domestic self-supply of protein. Impacts for conventional and organic farming are analysed in a partial equilibrium model of the Danish farm sector, which enables assessment of distributional effects between different farm types. The analysis suggests that crop production value and feed costs will increase, leading to a net economic loss in the conventional sector and a small gain for organic farming. Some variation across farm types in terms of adoption of biomass production and economic outcomes were found.

Root Growth and Nitrogen Utilization of a Leek Crop and an Undersown Catch Crop
Provedor de dados: Organic Eprints
Autores: Nielsen, Dr. Kai Lønne; Thorup-Kristensen, Dr. Kristian.
After its late harvest a leek (Allium porrum) crop will normally leave large quantities of nitrogen (N) in the soil which may be subject to leaching. A possible method to reduce N leaching losses is to establish a catch crop before the harvest of the leek crop. It was the aim of this study to investigate the effects of incorporating a catch crop in a leek crop with minimal competition and to monitor how root growth affected N availability across soil depths at different distances between catch and leek crop rows. To reduce competition between both crops leek was planted at 0.5 and 0.75 m row distances and chicory (Cichorium intybus) as a catch crop at an interrow spacing of 0.75 m. Minirhizotron glass tubes were inserted in the  middle of the interrow...

Kvælstof fra luften
Provedor de dados: Organic Eprints
Autores: Vinther, F.P.
Kløvergræs kan hente gratis kvælstof fra luften, men hvor meget drejer det sig egentlig om?  Bælgplanter, herunder de forskellige kløverarter, kan ved knoldbakteriers hjælp (symbiose) optage luftens kvælstof (N2), og derved udnytte denne uudtømmelige kvælstofkilde. Processen er simpelt-hen forudsætningen for at kunne drive økologisk jordbrug, og det har derfor stor interesse at kende størrelsen af N-fikseringen og have kendskab til hvilke faktorer der har betydning for derved om muligt at kunne optimere produktiviteten og reducere eventuelle miljømæssige effekter af et givet dyrkningssystem.

The aim of this study was to collect information about experiences of veterinarians with acupuncture. 27 German veterinarians who regularly used acupuncture on farm animals were interviewed. Most vets had received special training in acupuncture. This treatment method was most often used on horses, followed by cattle (mainly dairy cows). It was especially applied against common diseases which could easily be cured. Treatment costs were higher for horses than for cattle. There has been an increased demand for acupuncture mainly for horses.

Hållbart växtskydd. Analys av olika strategier för att minska riskerna med kemiska växtskyddsmedel
Provedor de dados: Organic Eprints
Autores: Cederberg, C; Wivstad, M; Bergkvist, P; Mattsson, B; Ivarsson, K.
Risker som är förknippade med kemiska växtskyddsmedel kan sammanfattas i fem områden: risker för användare, risker för rester i livsmedel samt i yt- och grundvatten och risker för natursystemet (t.ex. förlorad biodiversitet). De viktigaste fördelarna med växtskyddsmedel är att de bidrar till skördeökningar och att de förbättrar möjligheten till stabila skördenivåer, oavsett årsmån.    Det finns olika strategier för att hantera växtskyddet i dagens jordbruk och beroende på vilken strategi som väljs förändras riskerna som är förknippade med användningen av växtskyddsmedel. Syftet med MAT 21-projektet Hållbart Växtskydd har varit att analysera den miljömässiga hållbarheten i olika växtskyddsstrategier med hjälp av konkreta exempel. Ambitionen är att ge...

Soil Fragmentation and Friability. Effects of Soil Water and Soil Management
Provedor de dados: Organic Eprints
Autores: Munkholm, Lars J.
Soil fragmentation is a primary aim in most tillage operations in order to create a soil environment favourable for crop establishment and growth. Soils vary around the world from those exhibiting a self-mulching nature to those of a hardsetting nature. These extremes have been reported for Australian and other tropical and subtropical soils. In humid temperate climates, soil tillage is generally needed in order to produce a favourable environment for crop establishment and growth. The ease of preparing a favourable arable layer depends on complex interactions between climate, soil and the tillage implement. Especially soil water affects soil strength and fragmentation properties and thereby the ease of preparing a suitable arable layer. Soil management...

Autores: Köppen, Detloff.
Fazit  Mit der Erweiterung der EU wird der ökologische Landbau in den Beitrittsländern zu einer effektiven Alternative der Landbewirtschaftung. Unter Berücksichtigung der spezifischen Ausgangsbedingungen ist ein Marktanteil wie in den westeuropäischen Ländern möglich. Wichtigste Maßnahmen sind:  - die Schaffung der organisatorischen Voraussetzungen,  - die Entwicklung des inländischen Marktes,  - die Erschließung von Exportmöglichkeiten für ausgewählte Produkte.  Dazu muß die gesellschaftliche Akzeptanz weiter verbessert werden.

Anbau der Körnererbse in Mischkultur mit Gerste
Provedor de dados: Organic Eprints
Autores: Klaiss, Matthias; Weidmann, Gilles; Siegrist, Franziska.
Körnererbsen (oder Eiweisserbsen) tolerieren leichte Bodenfröste und können daher im Gegensatz zu Soja auch in kühleren Regionen angebaut werden. Allerdings neigt diese Leguminosenart zur Lagerung, was zu Ertragsausfällen führen kann.  In diesem Praxistipp wird der Anbau von Körnererbsen in Mischkultur mit Gerste propagiert, indem er das dazu erforderliche Vorgehen von der Saatbettbereitung bis zur Ernte detailliert erläutert und Empfehlungen zur weiterführenden Fruchtfolgegestaltung liefert. Weiter regt der Praxistipp dazu an, die Methode durch einen Vergleich der Erntemengen von Rein- und Mischkultur zu testen.

Greenhouse Gas Emissions of Organic and Conventional Foodstuffs in Austria
Provedor de dados: Organic Eprints
Autores: Lindenthal, Thomas; Markut, Theresia; Hörtenhuber, Stefan; Rudolph, Gwendolyn.
The consumer´s choice in quality of foodstuffs can influence GHG-emissions from the food sector. Organic agriculture is discussed as a possible way to reduce GHG-emissions. However the amount of reducing CO2eq per kg of organic products is unclear especially under supermarket conditions. The primary goal of the present study was to compare greenhouse gas emissions (CO2-eq) of organic foodstuffs with conventionally grown ones. All balanced foodstuffs are retail products, processed and marketed by nationwide supermarket companies in Austria.

Kann der Ökolandbau auch in der Zukunft auf die Nutztierhaltung bauen - Wie sieht es in der Praxis aus und wie soll / muss sie sich entwickeln?
Provedor de dados: Organic Eprints
Autores: Rahmann, Gerold; Koopmann, Regine; Oppermann, Rainer.
Die Diskussion über die Tierhaltung im Ökolandbau hat sich in den letzten Jahren beträchtlich intensiviert. Es ist allerdings schwierig, diese Diskussion auf einen einzigen gemeinsamen Nenner zu bringen und eine vorläufige Bilanz zu ziehen. Die  Diskussion wird auf sehr vielen und auf sehr unterschiedlichen Ebenen geführt.  Was sich beim Blick auf die verschiedenen Diskussionslinien allerdings aufdrängt, ist der Eindruck, dass die Zukunft der Ökologischen Tierhaltung von vielen Diskutanten mit beträchtlichen Fragezeichen versehen wird und dass sich diese Fragezeichen keineswegs auf untergeordnete Probleme beziehen.

Einfluss von mykotoxinbelastetem Streustroh auf die Fruchtbarkeit  von Zuchtsauen
Provedor de dados: Organic Eprints
Autores: Gutzwiller, Andreas; Gafner, Jean-Louis.
The effect of bedding straw contaminated with Fusarium mycotoxins (1.4 mg/kg deoxynivalenol  (DON) and 0.9 mg/kg ZON; median values) on the fertility of group housed  sows with daily access to pasture was tested using 48 sows kept on contaminated and  48 control sows kept on uncontaminated straw from mating until farrowing. No abortions  were observed. The contaminated straw neither influenced the pregnancy rate nor  the number and weight of the newborn piglets. DON up to 1.4 mg/kg and ZON up to  0.9 mg/kg in bedding straw seem to have no negative effects in sows having access to  roughage such as pasture grass. Straw without signs of deterioration, even if it may be  contaminated with Fusarium mycotoxins, is a suitable bedding material for pregnant  sows,...

Økonomi i økologisk løkproduksjon
Provedor de dados: Organic Eprints
Autores: Bysveen, Kari; Ebbesvik, Martha; McKinnon, Kirsty.
Landbruksdirektoratet melder om økende etterspørsel og omsetning av økologiske grønnsaker og mener det er potensiale for å øke den norske produksjonen. Økt omsetning skjer både i dagligvarehandelen og i andre salgskanaler som for eksempel storhusholdninger, Bondens marked og abonnementsordninger. Hvorvidt det er interessant for norske grønnsakprodusenter å øke produksjonen av økologiske produkter eller eventuelt legge om til økologisk drift, er blant annet et økonomisk spørsmål. I denne artikkelen presenteres økonomiske kalkyler for økologisk løkproduksjon basert på tre tenkte gårder.

Ny lovende efterafgrøde
Provedor de dados: Organic Eprints
Autores: Thorup-Kristensen, Kristian.
Når efterafgrøder etableres ved undersåning i korn, er det i praksis stort set altid rajgræs der anvendes. Men forsøg med forskellige efterafgrøder har vist at der kan være store fordele ved at vælge andre arter, både i miljøeffekt, i eftervirkning og i andre forhold. Vi har derfor undersøgt en række plantearter udsået som undersåede efterafgrøder i vårbyg. Flere af arterne har vist lovende egenskaber, der er bl.a. identificeret arter med markant dybere rodvækst end vi opnår med rajgræs. Farvevajd, som er en lille korsblomstret plante har vist sig velegnet til undersåning. Den er meget lovende, da den kombinerer en meget dyb rodvækst med lavt C/N forhold i biomassen og dermed en bedre eftervirkning end de fleste andre efterafgrøder.

Nitrogen and Energy Utilization on Conventional and Organic Dairy Farms in Norway
Provedor de dados: Organic Eprints
Autores: Koesling, Matthias.
To improve environmental sustainability it is important that all sectors in a society contribute to improving the utilization of inputs as energy and nutrients. In Norway, dairy farming contributes with an important share to the added value from the agricultural sector, although there is little information available about utilization of energy and nitrogen (N). Many results on sustainability have been published on dairy farming. However, due to Norway’s Nordic climatic conditions, mountainous and rugged topography and an agricultural policy that can design its own prices and subsidies, results from other countries are hardly representative for Norwegian conditions. To bridge this gap, the objective of this study was to analyse if the utilisation of...

Suitability of different dairy cow types for an Alpine organic and low-input milk production system
Provedor de dados: Organic Eprints
Autores: Horn, Marco; Steinwidder, Andreas; Gasteiner, Johann; Podstatzky, Leopold; Haiger, Alfred; Zollitsch, Werner.
The  implementation of  a  seasonal, site adapted, pasture-based milk production system as applied in New Zealand and North Western Europe might be an alternative for the near future in  Alpine regions. As in such a  low-input system the fertility and secondary traits such as robustness  against  metabolic  challenges  of   dairy cows  is   of   crucial  importance,   it  is questionable whether conventional dairy cow types, which were selected primarily for  milk production under high-input conditions, are most suitable. Therefore the aim of this study was to compare two different genotypes concerning their suitability for an organic, low-input milk production system under  Alpine  conditions.  Between  2008  and  2011 records  from 91 lactations of Brown...

Assessing the potential of organic farming for sustainable  livelihoods in developing countries - The case of cotton in India
Provedor de dados: Organic Eprints
Autores: Eyhorn, Frank.
Based on the example of cotton farming in India, this research examines in how far conversion to organic management can be a viable option for improving the livelihoods of farmers in developing countries. While cotton cultivation provides livelihood for an estimated 10 million Indian households, stagnating cotton yields, high input costs and low cotton prices have led many of them into indebtedness. By substituting synthetic fertilizers and pesticides with farm-own resources and labour, organic farming not only could have the potential to improve natural resource management, but also to reduce production costs and obtain a better price for the produce. Development agencies and companies are increasingly trying to utilize this potential by organizing...

NEMATODE COOMUNITIES AS INDICATORS OF SOIL QUALITY IN VINEYARD SYSTEM: A CASE OF STUDY IN DEGRADED AREAS
Provedor de dados: Organic Eprints
Autores: Landi, S.; D'Errico, G.; Simoncini, S.; L'Abate, G.; Priori, S.
The restoring effect of selective agronomic strategies on optimal soil functionality of degraded areas within organic vineyard was evaluated using the nematode community as an indicator of soil quality.  Three different restoring strategies were implemented in two organic farms located in Tuscany (Italy). The relative abundance of nematode trophic groups and the maturity index showed that the use of compost improved soil biological quality and increased the abundance of predators. Instead, dry mulching and green manure applications were useful to control the most dangerous nematodes of grapevines, namely the virus-vector Xiphinema index (Longidoridae).

Carbon footprints of crops from organic and conventional arable crop rotations – using a life cycle assessment approach
Provedor de dados: Organic Eprints
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...

Breeding Goals for Organic Dairy Farming in Denmark Based on the Principles of Organic Agriculture
Provedor de dados: Organic Eprints
Autores: Slagboom, Margot; Wallenbeck, Anna; Rydhmer, Lotta; Thomasen, Jørn Rind; Kargo, Morten.
Organic dairy farming (ODF) is different from conventional dairy farming in management practices, but so far the same breeding goal (BG) is used, based on the same economic models (EM). However, ODF is based on the principles of organic agriculture defined by the IFOAM, which are not easily interpreted in economic terms and it may be  uestionable to use a BG for ODF based on EM. In this study we set up three BGs for ODF in Denmark, one based on the  principles of organic agriculture, one focusing on roughage consumption and feed efficiency, and one focusing on disease resistance. A questionnaire and desired gains index were used to set up the BGs. Correlations between these BGs and BGs based on EM were low. Which BG would be best suitable to use for ODF in...

What are the limiting factors to seed quality in organic production of grass and clover seed and how to improve yield
Provedor de dados: Organic Eprints
Autores: Boelt, Birte; Gislum, René.
In conventional seed production of grasses and clover it is recognised that a low plant density in the seed crop stimulates the reproductive development and hence increase seed yield. Most temperate forage species of grasses and white clover establish slowly and have a relatively poor ground cover, which limits the competition against weeds. In order to optimise quality and yield in organic grass and clover seed production alternative establishment methods have been identified. These methods enhance crop competitiveness against weeds and allow for mechanical weed control.    Establishing the under sown seed crop right between the cereal cover crop row provides a higher ground cover, and the establishment rate of the seed crop is enhanced. This method of...

NJF-seminar Soil Stresses, Quality and Care    Different people understand differently the word soil. The soil can be looked upon as a body of nature and a part of the landscape. To many people soil is the substrate for plant growth and a prerequisite for food production and wealth. A third and perhaps growingly important view is soil as the physical ground for housings, roads and industry.    Soil is important to the whole society, not only for the agricultural sector. Soil has important ecological functions as it interacts with the dead bedrock, the atmosphere, the water, and the living organisms. Important functions are:    Biomass producer and transformer  Geomembrane, filter and buffer  Habitat for living organisms  Raw material and building ground...

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. Using atraditional metric conjoin tapproach based on an additive model, four product characteristics (productionmethod, price, size and information about farmer and rearing conditions)were varied in afractional factorial con-joint design, creating nine profilesof whole chickens. 384 Respondents rated the nine different chickens in terms of taste expectations and...

Co-existence with GMOs and organic seed production
Provedor de dados: Organic Eprints
Autores: Boelt, B.
Co-existence is defined as the farmers being able to choose between conventional, organic and genetically modified (GM) crop production, in compliance with the relevant legislation on labelling rules and purity standards.  Genes of cultivated plants spread in time and space through pollen and seed dispersal, and in addition handling during transport and processing may also disperse seeds.   Consequently, suitable measures during cultivation, harvest, transport, storage, and processing are necessary to ensure co-existence in the supply chain of propagated seed. With the increasing area of GM-crop production as well as in the number of crops in which GM-varieties are available the need for guidelines to ensure coexistence are becoming increasingly essential....

Tema om økologisk mælkeproduktion
Provedor de dados: Organic Eprints
Autores: Mogensen, Lisbeth.
I fremtidens økologiske mælkeproduktionssystemer forventes øget fokus på selvforsyning med foder. Foderforsyningen vil i stigende grad blive baseret på grovfoder som græs, majs og helsæd, der under danske dyrkningsbetingelser har et højere udbyttepotentiale end mere proteinrige og koncentrerede afgrøder som ærter, lupiner og korn til modenhed.

Forsknings- og udviklingsaktiviteter på området reduceret jordbearbejdning
Provedor de dados: Organic Eprints
Autores: Schjønning, P.; Jørgensen, M.H.; Olesen, J.E.; Rasmussen, G.; Munkholm, L.J.; Melander, B.
Der er fra det danske landbrugserhverv formuleret ønske om, at der iværksættes en bedre rådgivning omkring gennemførelse af reduceret jordbearbejdning, herunder direkte såning (FRDK, bl.a. ved mødet i Forskningskontoret 18. januar 2001). Problemstillingen har interesse for såvel konventionelle som økologiske jordbrugere, idet reduceret bearbejdning af jorden som udgangspunkt er positivt for jordkvaliteten. Der er gennemført en lang række undersøgelser omkring reduceret jordbearbejdning og direkte såning i Danmark. En række forhold har dog til dels gjort disse resultater forældede. Det skyldes bl.a. den politisk bestemte udvikling i de dyrkede afgrøder, herunder i særlig grad sædskiftet, som har stor betydning for reduceret jordbearbejdning. De gennemførte...

Autores: Rasmussen, Ilse A.
På en studietur i det sydøstlige Australien besøgte jeg to økologiske landbrug, som begge brugte præparater og såede i forhold til månens stilling. Generelt oplevede jeg en stor interesse for forskellige alternative tiltag - og ikke kun blandt økologer. Jeg stødte på firmaer som BioAg og Biological Farming, der sælger produkter, som skal fremme livet i jorden og dermed også gerne udbytterne. Også på IFOAM- og den videnskabelige ISOFAR-konference fornemmer man, at der er mere gang i biodynamikken og andre alternativer i Australien end herhjemme.

Empirical model for quantification of symbiotic nitrogen fixation in leguminous crops
Provedor de dados: Organic Eprints
Autores: Høgh-Jensen, Henning; Loges, Ralf; Jensen, Erik Steen; Jørgensen, Finn V.; Vinther, Finn P.
Symbiotically fixed N2 (SNF) is an important input of nitrogen (N) in many cropping systems. In spite of this fact, the input of fixed N to a particular cropping system is usually not known, and an exact estimation of the amount of N2 fixed requires laborious measurements. Consequently, there is a demand for a simple and reliable tool to estimate N2 fixation in leguminous crops. A model is here proposed for quantification of SNF in leguminous crops in different arable systems. The model estimates SNF using dry matter yield as input and cropping system specific values for the parameters: N concentration in dry matter and the proportion of the N in the legume that is derived from the atmosphere. Further, the model includes fixed N not included in the...

SUSTAINABILITY OF POULTRY PRODUCTION USING THE EMERGY APPROACH: COMPARISON OF CONVENTIONAL AND ORGANIC REARING SYSTEMS
Provedor de dados: Organic Eprints
Autores: CASTELLINI, Prof C; BASTIANONI, Dr S; GRANAI, Dr C; DAL BOSCO, Dr A; BRUNETTI, Dr M.
The organic production system is an important strategy, compatible with sustainable agriculture, avoiding the use of chemical compounds,limiting the intensity of production and providing controls along the entire chain of production. The aim of this study is to compare conventional and organic poultry production in terms of emergy analysis. The main differences in the two systems were the emergy cost for poultry feed and for cleaning/sanitization of the buildings between successive productive cycles. In both production systems the poultry feed represented more than 50% of the emergy flow. Regarding the agronomic phase, it was shown that almost all the organic crops, avoiding  chemical fertilizers and pesticides, saved around 60% emergy. The emergetic costs...

The aim of the present study was to investigate the effects of prepartum reticuloruminal pH values on postpartum pH values of lactating cows at two concentrate supplementation levels. An indwelling pH measurement system with a wireless data transmitting unit was given to 9 heifers and 11 cows orally 2 weeks before expected calving. The pH was measured from week 2 prepartum to week 6 postpartum. Prepartum, all animals were fed hay and grass silage only. After parturition the animals were assigned to one of two concentrate supplementation levels (Con and Low). During the first 6 weeks postpartum, 5.6 kg and 2.9 kg dry matter per day of concentrates were fed to cows in groups Con and Low, respectively. Before parturition, no effect of the week on the mean pH...

Spisekvalitet af økologisk kød fra unge krydsningsdyr
Provedor de dados: Organic Eprints
Autores: Therkildsen, M.; Vestergaard, M.
Produktionen af økologisk kød fra ungdyr er ikke særligt udbredt i Danmark til trods for et veletableret økologisk mælkeproduktionssystem, som egentlig godt kunne levere tyrekalvene til den økologiske kødproduktion. I stedet bliver disse kalve solgt til konventionelle kødproducenter på grund af lave udbytteresultater i de økologiske produktionssystemer.  Formålet med dette projekt var at afprøve et koncept til production af økologisk kød fra ungkvæg baseret på krydsningsdyr fra malkekøer kødkvægstyre. Resultaterne viser, at kvie- og ungtyrekrydsninger af Limousine x Holstein kan være et alternativ til renracede Holstein ungtyre i økologisk oksekødsproduktion grundet den øgede tilvækst og form-klassificering, aroma og smag hos krydsningsdyrene.

Verhalten und Wachstum von Ferkeln nach der Kastration  unter Injektions- oder Inhalationsnarkose
Provedor de dados: Organic Eprints
Autores: Baldinger, Lisa; Traulsen, I.; Weißmann, Friedrich; Bussemas, Ralf.
In German organic agriculture, general anaesthesia of male piglets before castration is commonly performed by injection of ketamine and azaperone, plus application of the analgesic meloxicam. Inhalation anaesthesia with isoflurane (plus meloxicam) is an alternative with a shorter recovery phase and widely used in Switzerland, but requires reclassification for pigs on a case to case basis in Germany. In order to provide data on piglets´ behavior after castration and potential long-term effects on growth until  weaning, a trial under practical conditions on an experimental farm was conducted. Body weight development until weaning was not affected by the method of  anaesthesia. However, piglets anaesthetised with injection showed significantly more motoric...

A review is given of the last 5 years research on soil structure dynamics carried out at the Danish Institute of Agricultural Sciences. The studies were initiated as part of a large programme focussing on the development of organic farming in Denmark. In organic farming a healthy and living soil is highly valued. Holistic thinking is also a key element in the organic farming concept. In order to integrate a holistic thinking in our soil structure research a multidisciplinary approach was adapted that integrated soil physics, chemistry and microbiology. In addition, soil structure was studied at different levels from undisturbed “whole soil” in the field to specialized reductionistic studies using size separated or remoulded soil in the laboratory.

Energi i økologisk jordbrug. Reduktion af fossilt energiforbrug og produktion af vedvarende energi
Provedor de dados: Organic Eprints
Målsætningen om at reducere forbruget af fossil energi er klart formuleret i de økologiske principper. Desuden er der både forsyningsmæssige og geopolitiske grunde til, at det kan være klogt at fremtidssikre økologisk jordbrug ved at øge selvforsyningsgraden. Men hidtil er der ikke sket en målrettet indsats inden for økologisk jordbrug på dette felt. Analyser i denne vidensyntese viser dog, at potentialet for produktion af vedvarende energi i økologisk jordbrug er stort, således at det teoretisk set er forholdsvis let at blive selvforsynende med det direkte energiforbrug.     I rapporten er der hovedsageligt fokuseret på energiteknologier, som inden for en kort tidshorisont kan implementeres, og på teknologier, som kan udnyttes decentralt på den enkelte...

Modelling root distribution and nitrogen uptake
Provedor de dados: Organic Eprints
Autores: Pedersen, Anders; Thorup-Kristensen, Kristian.
Plant soil and atmosphere models are commonly used to predict crop yield and environmental  consequence. Such models often include complex modelling modules for water movement,  soil organic matter turnover and, above ground plant growth. However, the root modelling in these models are often very simple, partly due to a limited access to experimental data. We present a two-dimensional model for root growth and proliferation. The model focuses on annual crops, and attempt to model root growth of the crops and its significance for N uptake from different parts of the soil volume.

CONVERSION OF A LAMB PRODUCTION SYSTEM TO ORGANIC FARMING: HOW TO MANAGE, FOR WHAT RESULTS?
Provedor de dados: Organic Eprints
Autores: Benoit, Marc; Tournadre, Hervé; Dulphy, Jean-Pierre; Cabaret, Jacques; Prache, Sophie.
Two sheep flocks were managed organically for two years from conversion under different lambing strategies (1 lambing/year vs. 3 lambings every two years). The second system was tested because pf a producer’s interest in high productivity, which is a guarantee of good economic results in conventional production.. Reproduction, feeding, lamb production, carcass quality, health (particularly internal parasitism), economic return of the flock, grass production, and pasture biodiversity were evaluated. The lambs were bred with low therapeutic inputs. No economic advantage of increasing lambing frequency was demonstrated, whereas this strategy complicated management and resulted in higher internal parasitic infection of the lambs, and finally showed lower...

Anaerobic digestion for closing the loop of a biorefinery for organic farming: Production of biogas and organic fertilizer from process residues
Provedor de dados: Organic Eprints
Autores: Fernandez, Maria Santamaria; Ytting, Nanna Karkov; Lübeck, Mette; Uellendahl, Hinrich.
The availability of organic animal feed for monogastric animals and organic fertilizer is in many regions a limiting factor for the further spread of animal breeding and crop cultivation in organic farming. The production of these two commodities is the main target of a green biorefinery concept based on regionally organically grown grass biomass, called Organofinery. Anaerobic digestion of the residual streams after protein separation for the organic feed product is a key process to extract both the energetic and the nutritional value of the residual biomass in the biorefinery. Biogas potentials of the residual streams from the processing of red clover and clover grass (press cake obtained from screw pressing to produce green juice and brown juice after...

Simulating Soil Organic Matter Transformations with the New Implementation of the Daisy Model
Provedor de dados: Organic Eprints
Autores: Petersen, Anders; Bruun, Sander; Jensen, Dr. Lars Stoumann; Hansen, Dr. Søren.
Daisy is a well-tested deterministic, dynamic soil-plant-atmosphere model, capable of simulating water balance, nitrogen balance and losses, development in soil organic matter and crop growth and production in crop rotations under alternate management strategies. Originally it was developed as a system of single models describing each process involved, but recently it has been developed into a framework, which can be used for implementation of several different models of each of the different processes. Thus, for example a number of different models for simulating soil water dynamics can be chosen depending on the purpose of the simulation and the availability of data for parameterisation.   The sub-model simulating soil organic matter is still a fixed...

Autores: Meerburg, BG; Bonde, M; Brom, FWA; Endepols, S; Jensen, AN; Leirs, H; Lodal, J; Singleton, GR; Pelz, H-J; Rodenburg, TB; Kijlstra, A.
From 26 to 28 May 2004 an international seminar was held in Wageningen, the Netherlands, about current knowledge and advice on rodent management on organic pig and poultry farms in Western Europe. This paper summarizes the discussions. Rodent management is necessary to protect the food production chain from health hazards to livestock and humans.Some organic farmers prefer biological rodent control, but since rodents can also transmit diseases this bears certain risks for the production of healthy livestock and safe food. Effective rodent management requires a thorough understanding of the biology of the pest species concerned. These can be divided into two groups: field rodents, such as voles, and commensal rodents like house mice and rats. The objective...

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.

Certified organic agriculture stipulates a range of principles and standards, which govern farmer practices. The recent global expansion of organic agriculture has raised new challenges for organic agriculture, particularly whether management practices in organic farms are subject to the forces of conventionalisation. We studied changes in agroecological practices in certified organic farms in China, Brazil and Egypt. The study takes departure in the conventionalisation hypothesis and the analysis is framed using organic and agroecological principles. The study focuses on agroecological design principles, inherent to organic agriculture, of diversity in crop production, pest, disease and weed management, and soil fertility management. The research design...

Biosafety data improving the regulation of Co-existence
Provedor de dados: Organic Eprints
Autores: Boelt, B.
Co-existence is defined as the farmers being able to choose between conventional, organic and genetically modified (GM) crop production, in compliance with the relevant legislation on labelling rules and purity standards. Genes of cultivated plants spread in time and space through pollen and seed dispersal, and in addition handling during transport and processing may also disperse seeds. Consequently, suitable measures during cultivation, harvest, transport, storage, and processing are necessary to ensure co-existence.

The Role of Animals in Eco-functional Intensification of Organic Agriculture
Provedor de dados: Organic Eprints
Autores: Vaarst, Mette.
Eco-functional intensification is understood as building synergies in multi-functional and resilient agricultural systems in harmony with their surrounding environment and human systems, to the benefit of diversified production of food and beyond, as in, for example, ecosystem services. Integration of animals into eco-functionally intensified agricultural systems to enhance agricultural, ecological and social systems, can contribute to driving a future sustainable development of organic agricultural and food systems. This approach may respond to challenges of an increasing industrialization of livestock in the global north, a process which has led to heavy reliance on external inputs, and, to a large extent, a detachment of animals from farming systems,...

Decentralizing and liberalizing EU regulations on seeds and plant genetic resources. A Danish case study
Provedor de dados: Organic Eprints
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...

Do organic livestock farms differ from low-input conventional ones? Insights based on beef cattle in southern Europe
Provedor de dados: Organic Eprints
Autores: Escribano, A.J.
The objective of this study is to determine whether there are clear differences between conventional (but low-input) and organic beef cattle farms located in the Southwest of Spain. 33 conventional and 30 organic farms were compared in terms of structure, technical management, and performance. The results showed that organic farms (‘All Organic’) mainly focus on the production of calves at weaning age which are fattened in conventional holdings (‘Organic 1’; n= 22). The remaining organic farms (‘Organic 2’; n=11) showed to participate in almost all stages of the agri-value chain. ‘Conventional’ farms were mainly dedicated to producing calves at weaning age (similarly to Organic 1).  Organic 1 had the smallest herd size: 80.18 LU, p&lt;0.05). Organic 2...

Kløversnudebiller og kløvergnavere kan forårsage udbyttetab i hvidkløver til frø. Ved Danmarks JordbrugsForskning er der de sidste fem år lavet et forsøg, der har til formål at bestemme snudebillernes skadevirkning. Der blev i gennemsnit af de fem års forsøg målt et merudbytte på ca. 40 pct. ved at bekæmpe snudebiller. Forsøgene kan ikke bruges til at belyse, hvor mange sprøjtninger det er nødvendigt at udføre mod snudebiller.

Re-thinking Organic Trout Production /(ShelterFish)
Provedor de dados: Organic Eprints
Autores: Jokumsen, Alfred.
Opdræt af regnbueørred, især økologisk ørred, er kritisk udfordret på grund af relativt mange hud/gælle infektioner forårsaget af forskellige patogener, især parasitten Costia (Ichthyobodo necator), som ultimativt er dødelig for yngel/mindre fisk. Dette kan være en trussel mod tilstrækkelig udbud af økologisk yngel til videre produktion, da regelsættet for økologisk akvakultur kræver 100% økologisk yngel. Endvidere forårsager en såkaldt ny ”Rickettsia-lignende" bakterie “rødpletsyge” (RMS), dvs. røde pletter i huden, som medfører ned-klassificering/kassation af op til 30% af fiskene ved slagtning. Behandling ved brug af antibiotika/hjælpestoffer er kun muligt i begrænset omfang i økologisk ørred produktion. Løsninger til forebyggelse og/eller behandling af...

Et længere kælvningsinterval betyder færre golddage samtidig med, at ydelsen i starten af laktationen tilsyneladende kan øges, således at der opnås mindst samme ydelse per årsko. Det kræver imidlertid et højt foderniveau, idet årsydelsen falder mere ved det lange kælvningsinterval end ved normalt kælvningsinterval, når foderniveauet reduceres.

Det sværeste ved hvidkløver er afpudsningen
Provedor de dados: Organic Eprints
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.

Intercropping grain peas with barley
Provedor de dados: Organic Eprints
Autores: Alföldi, Thomas; Clerc, Maurice; Stöcklin, Milo.
Intercropping of legumes with cereals is a promising possibility to produce fodder protein while creating few costs and using few resources.    Practicable cultivation methods of intercropping with protein peas/barley and field beans/oats were developed, both with mixing ratios of 80% and 40%, respectively, of the usual local seeding amount for the single crop (possible for winter crops as well as for spring crops).     The grain serves as a support crop, suppresses weeds and provides a risk coverage in years of poor grain legume development.    Since 2010, the acreage of organic peas and beans, mostly grown in mixed cultures, has multiplied.     This increase was also possible due to mills that buy and separate the yield of intercropping systems into its...

Co-operative or coyote? Producers' choice between intermediary purchasers and Fairtrade and organic cooperatives in Chiapas
Provedor de dados: Organic Eprints
Autores: Milford, Anna Birgitte.
This study of organic and Fairtrade co-operatives in Mexico aims to find out why many coffee producers prefer not to join the certified co-operatives, despite their higher price offer. A study of costs of production of organic coffee concludes that it implies more work, but not necessarily higher yields. A main conclusion of the investigation is that the compulsory organic production methods deters many producers from entering the co-operatives, and that it is more attractive for producers with more free family labour, and less attractive for producers with very little coffee land. However, the study also shows that it is not only economic factors that influence the decisions of the producers on where to sell their coffee.  Previous studies have shown that...

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: Organic Eprints
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...

Cultivars and cultivation systems for organic strawberry production in Norway
Provedor de dados: Organic Eprints
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...

Optimum Returns in Irrigated Groundnut as Influenced by  Poultry Manure Rates at Kadawa in the Sudan Savanna  Ecological Zone of Nigeria
Provedor de dados: Organic Eprints
Autores: Ibrahim, Usman; Rahman, Shehu Abdul.
Groundnut has been reported to be one of the most important oil crops in the world. It plays an important role in the diets of rural populations, livestock feeding and soil fertility particularly in developing world. The yield from farmers’ field has been low due to several factors. Increased groundnut production can be achieved through irrigation to complement the rainy season production while its productivity can be enhanced by the use of a safer and available alternative source of fertilizer like the poultry manure. This work was therefore undertaken to determine economic optimum level of poultry manure in groundnut production under irrigation. To achieve this objectives field trials were conducted during the 2012/2013 and 2013/2014 dry seasons at the...

Autores: Moudry, Jan (Jr.); Friebel, Ludvik; Konvalina, Petr.
Setrvalé zemědělství je v současné době výrazně podporováno Evropskou unií, což se pozitivně odráží i na vývoji ekologického zemědělství členských států. I v České republice je u podílu ekologického hospodaření patrný rostoucí trend, přičemž nezanedbatelný podíl na tom má i nastavení dotačních titulů. Přestože by však tyto měly být vybalancovány takovým způsobem, aby v dostatečné míře podpořily rozvoj šetrného hospodaření ve všech směrech, dochází v ČR v EZ k vysokému nárůstu hospodaření na trvalých travních porostech (TTP) za současného útlumu využívání orné půdy. Článek se zabývá rozborem hospodaření výběrového souboru ekologických podniků, se zaměřením na hospodaření na TTP a využívání agroenvironmentálních programů.

Muttergebundene Kälberaufzucht – mehr lieferbare Milch durch temporären Kalbkontakt?
Provedor de dados: Organic Eprints
Autores: Barth, Kerstin; Kälber, Tasja; Brückmann, Caroline; Häußermann, Angelika; Waiblinger, Susanne.
Die reduzierte Menge an lieferbarer Milch ist ein Nachteil der muttergebundenen Kälberhaltung. Die Limitierung des Kuh-Kalb-Kontaktes könnte eine Lösung sein. In unserer Studie wurden die Kälber in der Nacht zu ihren Müttern gelassen und zwischen Morgen- und Abendmelkzeit separiert (n=18). Die Menge der von diesen Kühen maschinell ermolkenen Milch lag um ca. 14 kg/ Tag niedriger als bei den Kontrollkühen (n=20), die keinen Kontakt zu ihren Kälbern hatten. Diese Differenz ist nicht viel kleiner als in früheren Studien in denen die Kälber permanent Kontakt zu ihren Müttern hatten. Zudem weist der reduzierte Fettgehalt der Milch säugender Kühe auf eine gestörte Alveolarmilchejektion hin. Folglich führt ein begrenzter Kuh-Kalb-Kantakt zu keiner bemerkenswerten...

Biotic and abiotic binding and bonding mechanisms in soils with long-term differences in management
Provedor de dados: Organic Eprints
Autores: Elmholt, Susanne; Munkholm, Lars J.; Debosz, Kasia; Schjønning, Per.
During the last decades Denmark has experienced a growing interest in low-input farming systems like organic farming. These systems rely on a high soil fertility to maintain nutrient availability and plant health. Soil aggregation contributes to this fertility, because it is crucial to soil porosity, aeration and infiltration of water. This paper reports a study of two pairs of differently managed, neighboring fields. The aim was to elucidate long-term effects of the different farming systems on physical and biological variables with influence on bonding and binding mechanisms of soil aggregation. Each pair consists of an organically grown dairy farm soil, based on a forage crop rotation system, including grass (Org-FCS(G)) and a conventionally managed...

The Organic-Conventional Comparative Dairy Systems trial at Massey University began in August 2001, and the organic farmlet achieved certification in August 2003.  The trial is unique because it is the only comparative grassland-based open grazing dairy study in the world.  The organic and conventional systems are managed individually according to best practice, and both are intensively monitored for production, animal health, and environmental impacts.  The systems remained similar for the first two years, but began to diverge in the third and fourth years.  Production has been 10-20% lower on the organic farm, but environmental impacts appear to be less than on the conventional unit, and net incomes would be similar given a 20% price premium for the...

Ekologiskt lantbruk har genomgått en rask utveckling från marginell proteströrelse för ideologiskt medvetna entusiaster på 1970-talet, till en bidragsberättigad del av dagens etablerade lantbruk. Åsikterna om ekologisk djurhållning har varit många och starka genom åren, och en återkommande kritik har gällt djurens hälsa och välfärd. Åtskilliga har menat att ekologiska djur i dessa avseenden har haft det sämre ställt än konventionella  djur. De menar att detta t.ex. visat sig i problem med allt för magra slaktkroppar från ekologiska djur eller från djur som tvingats vistats ute i ur och skur, stundtals i leriga hagar med undermålig hygien, och ett regelverk som lägger hinder för adekvat medicinsk behandling. Åter andra har menat motsatsen – ekologisk...

I Europa er det anerkendt, at forbrugeren skal have mulighed for at vælge mellem økologiske, konventionelle og gen-modificerede afgrøder. Det er også tilkendegivet, at man ønsker at have mulighed for at udnytte de potentialer udviklingen inden for bioteknologi – herunder anvendelse af genmodificerede afgrøder har På samme tid skal det imidlertid sikres, at ingen former for jordbrug afskæres fra fremtidige udviklingsmuligheder. Herfra stammer begrebet ’sameksistens’.    For at sikre sameksistens er det nødvendigt at kunne identificere produkterne fra de forskellige produktionsformer – eksempelvis ved mærkning. Ø-mærket karakteriserer et økologiske produkt, som har gennemgået en certificeret produktion, i hvilken bl.a. anvendelse af genmodificerede afgrøder...

Can weed management in vegetable systems be improved by cover crop species mixtures? Step 2: field implementation
Provedor de dados: Organic Eprints
Autores: Ranaldo, Marzia; Carlesi, Stefano; Costanzo, Ambrogio; Bàrberi, Paolo.
Cover crops are a fundamental tool for weed control, especially in organic and low input farming. Species with different functional traits can be combined in mixtures to enhance weed suppression. Our aim was to test the relative importance of functional diversity and functional composition (i.e. complementarity) in improving and stabilising the agroecosystem services expected from cover crops.  Following a preliminary screening on cover crop functional traits (Step 1), we identified 8 species belonging to 4 functional groups: large seeded legumes, characterized by higher height (Pisum sativum L., Vicia sativa L.), small seeded legumes, able to cover quickly the soil (Trifolium incarnatum L., T. squarrosum L.), highly competitive grasses (Hordeum vulgare...

Avaliação de um modelo de rastreabilidade para produtos orgânicos a partir de certificadoras paranaenses.
Provedor de dados: Organic Eprints
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...

Direct and mediated impacts of product and process characteristics on consumers’ choice of organic vs. conventional chicken (D.6.8)
Provedor de dados: Organic Eprints
Autores: Marian, Livia; Thøgersen, John.
There is a lack 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. Using a traditional metric conjoint approach based on an additive model, four product characteristics (production method, price, size and information about farmer and rearing conditions) were varied in a fractional factorial conjoint design, creating nine profiles of whole chickens. 384 respondents rated the nine different chickens in terms of taste expectations...

Provedor de dados: Organic Eprints
Autores: Tein, Berit; Kauer, Karin; Eremeev, Viacheslav; Luik, Anne; Selge, Are; Loit, Evelin.
The aim of this study was to investigate how different farming systems influenced tuber yields and quality (N, NO3−, P, K, Ca, Mg, dry matter and starch concentrations) of potato as well as how potato cultivation within a crop rotation under different farming systems affects soil quality (pH, Ntot, Corg, plant available P, K, Ca and Mg concentrations). Potato (Solanum tuberosum L.) was part of a five crop rotation experiment in which red clover (Trifolium pratense L.), winter wheat (Triticum aestivum L.), peas (Pisum sativum L.), potato and barley (Hordeum vulgare L.) followed each other simultaneously on a same field. Data presented in this paper concerned the first 3 years of the rotation during 2009–2011. The experiment was performed with six different...

Managing soil fertility in organic farming systems
Provedor de dados: Organic Eprints
Autores: Watson, C.A.; Atkinson, D.; Gosling, P.; Jackson, L.R.; Rayns, F.W.
Complex relationships exist between different components of the organic farm and the quantity and quality of the end products depend on the functioning of the whole system. As such, it is very difficult to isolate soil fertility from production and environmental aspects of the system. Crop rotation is the central tool that integrates the maintenance and development of soil fertility with different aspects of crop and livestock production in organic systems. Nutrient supply to crops depends on the use of legumes to add nitrogen to the system and limited inputs of supplementary nutrients, added in acceptable forms.  Manures and crop residues are carefully managed to recycle nutrients around the farm. Management of soil organic matter, primarily through the...

Modelling dry matter production and resource use in intercrops of pea and barley
Provedor de dados: Organic Eprints
Autores: Berntsen, Jørgen; Hauggard-Nielsen, Henrik; Olesen, Jørgen E.; Molt Petersen, Bjørn; Jensen, Erik Steen; Thomsen, Anton.
The FASSET whole farm model was extended with a sub-model for competition between several plant species for light, water and nitrogen. The new model was tested on intercrops of pea (Pisum sativum L.) and spring barley (Hordeum vulgare L.). A three-year dataset on pea and barley sole crop growth was used for calibration. Two datasets that included detailed measurements of crop production, nitrogen uptake and leaf area indices from two sites were used for testing. An arable organic experiment from three sites including several treatments over four years was also used for testing.    The model predicted the increase in resource utilisation of pea and barley and effects on pea symbiotic nitrogen fixation satisfactorily. The effects of pea interspecific...

Mineralization and microbial assimilation of 14C-labeled straw in soils of organic and conventional agricultural systems
Provedor de dados: Organic Eprints
Autores: Fliessbach, Andreas; Mäder, Paul; Niggli, Urs.
An incubation experiment on straw decomposition was carried out with soils from a long-term field trial at Therwil, Switzerland. Two conventional agricultural systems, one with (CONFYM) and one without manure, an organic system managed according to bio-dynamic farming practice (BIODYN) and an unfertilized control were compared. CONFYM received stacked manure and an additional mineral fertilizer. BIODYN received composted farmyard manure and no mineral fertilizers. Both systems received the same amount of manure based on 1.4 livestock units haˇ1. The aim of the investigation was to explain the large differences in soil microbial biomass and activity between the systems, especially between the manured soils. Di€erences in microbial C-utilization effciency...

Delprojektet om Natur- og miljøscenarier formulerede 4 måder at omlægge 25% af et konkret værkstedsområde til økologisk jordbrug. I scenariet ”Mælk” var det fortrinsvis kvægbrug, der blev omlagt. Scenariet ”1997” var også domineret af mælkeproducenter, men med et tillæg af planteavlsbedrifter. Scenariet ”Planter/svin” omfattede udelukkende svine- og planteavlsbrug, og scenariet ”Selvforsyning” omfattede bedrifter i et udpeget SFL-område, som ikke måtte supplere produktionen med indkøbt foder. Resultaterne pegede på en tendens til fald i kvælstofudvaskningen i hele området i tre scenarier, mens der var uklarhed m.h.t. det fjerde - ”Planter/svin”- scenariet. Belastningen med pesticider blev reduceret. I scenarierne ”Mælk” og ”1997”var reduktionen mindre end...

Nutzung pflanzengenetischer Ressourcen für den ökologischen Landbau am Beispiel von Wintererbsen
Provedor de dados: Organic Eprints
Autores: Urbatzka, MSC Peer; Graß, Dr. Rüdiger; Schüler, Dr. Christian.
Winter peas were cultivated in Germany in the first half of the 20th century for green manure, green forage or as a threshing crop. So far they are mainly used in field ex-periments, e.g. at the University of Kassel. But winter peas are very interesting for or-ganic farming, because of their high N-fixation rate and their ability to suppress weeds effectively. In the vegetation period 2002/2003 twelve genotypes of winter peas from the German genebank in Gatersleben were examined in field trials. In the long and cold winter of 2002/2003 eight different genotypes from Germany, Hungary and the Balkan survived. The yield of the eight accessions as green forage and as a threshing crop (yield between 3 – 4 t/ha) are promising.

Integrated production of tree biomass and piglets - Effect of paddock design on sow excretory behaviour
Provedor de dados: Organic Eprints
Autores: Andersen, H.M-L.; Kongsted, A.G.; Jakobsen, M.
In systems with an integrated production of trees and piglets it is important that the lactating sows are motivated to urinate and defecate adjacent to the trees to reduce nutrient losses. Adding poplar trees in one end of individual pasture-based paddocks did not motivate the sows to choose the area with trees for elimination independent of paddock design. The location of feed and hut influenced the sows’ excretory behaviour and the effect differed between the different combination of feed and hut location. Future work should focus further on overall paddock design to optimize nutrient uptake and to ensure an outdoor system that from both a welfare- and environmentally point of view is sustainable.

Autores: Skonieski, Fernando Reimann; Viégas, Julio; Cruz, Pablo; Nornberg, José Laerte.
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....

Provedor de dados: Organic Eprints
Autores: Beckmann, Uta; Kolbe, Hartmut; Model, Annett; Russow, Rolf.
Die Entwicklung der Landwirtschaft war in den letzten Jahrzehnten gekennzeichnet durch einen beispiellosen Anstieg des Dünge- und Pflanzenschutzmitteleinsatzes sowie durch entsprechend starke Ertragssteigerungen. Die damit verbundenen nachteiligen Umweltwirkungen auf Wasser, Boden und Atmosphäre führten einerseits zur Suche nach Optimierungsstrategien und andererseits zu erhöhten Anstrengungen bei der Prüfung alternativer Bewirtschaftungsformen.  Zur Prüfung von Ackerbausystemen des ökologischen Landbaus wurden ab dem Jahr 1992 komplexe Dauerversuche angelegt. Es wurden Verfahren von viehlosen sowie von viehhaltenden Betrieben simuliert. In den Versuchen wurden außerdem eine stark unterschiedliche Düngungshöhe mit verschiedenen organischen Düngemitteln...

Management of grasslands in intensive dairy livestock farming
Provedor de dados: Organic Eprints
Autores: Kristenseen, Troels; Søegaard, Karen; Kristensen, Ib Sillebak.
By the intensifying of the livestock production with specialised and larger farm units the role of grassland has been reduced. The change in EU policy from a production-oriented marked to a marked where the choice of crop is linked to its added value; grassland has an opportunity to come back. However, the aim for research and farming practice within grassland management should be seen in this new context. The paper reviews different production and management systems, mainly stressed on grazing systems, within intensive dairy farming and aspects of feeding and quality of herbage in order to propose areas of special interest seen in the new context. Farming systems based on homegrown feed, as organic farming and systems based on legumes, need to be further...

Autores: Marques, Paulo Jorge Pazin; Richter, Ana Simone; Nazareno, Nilceu Ricetti Xavier.
A cultura da batata (Solanum tuberosum L.) tem grande importância econômica no Paraná, tendo sido este o maior produtor da batata do Brasil. Mudanças de mercado e tecnológicas fizeram com que os produtores saíssem da atividade. A região metropolitana de Curitiba era a responsável por grande parte da produção da chamada “batata-comum”, que estava na mão de agricultores familiares. Ainda, têm aumentado as restrições legais de uso da terra face à demanda crescente por mananciais de água. Com isso, os produtores locais têm necessidade de converter suas áreas para sistemas alternativos de produção, com a eliminação gradativa de insumos químicos. A Agricultura Biodinâmica oferece possibilidades de produção nas condições descritas, mas não existem trabalhos...

Computer model for simulating the long-term dynamics of annual weeds under different cultivation practices
Provedor de dados: Organic Eprints
Autores: Rasmussen, I.A.; Holst, N.; Pedersen, L.; Rasmussen, K.
A model is being developed which describes the population dynamics of annual weeds and how it is affected by crop rotation, cultivation practices and weed control. The model aims to predict the development of a certain weed species in order to plan crop rotation and cultivation practices to minimize the risk of proliferation. The model does not predict the exact number of weeds expected to be found in a certain year or crop, but rather the general development over a number of years. The model includes documented knowledge, as well as informal expert knowledge, on seed survival in the soil, seed placement in soil after tillage, seed germination with respect to placement in soil, time of year and tillage, weed development in response to crop competitiveness...

Autores: D'Avino, L.; Priori, S.; Schroers, H.J.; Tangolar, S.; Tardaguila, J.; Giffard, B.; Fantappiè, M.; Costantini, E.A.C.
Degraded areas are frequent in vineyards, even if managed by organic farming, mainly caused by soil truncation, soil erosion, or salts enrichment. Recovering strategies implemented in 19 degraded vineyards in 5 countries within the RESOLVE project concerned: (i) composted organic amendments, or seeding of cover crops (including legumes) for (ii) green manure or (iii) dry mulch. The relationships between vineyard management and pedo-climatic conditions are useful to better understand other contributions dealing with RESOLVE project reported in the present special issue. The results suggested that the nature of degradation requires optimum seedbed preparation to grow green manure crops. Whereas dry mulching plants needs less tillage operations (neither...

Så meget koster øko-hømælk at producere
Provedor de dados: Organic Eprints
Autores: Tvedegaard, Niels; Kristensen, Troels.
”Hømælk” er mælk fra køer hvor foderensilagen er skiftet ud med hø. Det foderskifte koster penge! Produktionen kræver fx faciliteter til håndtering og tørring af høet, græsudbyttet i marken falder, der er omkostninger til energi ved nedtørringen og mælkeydelsen falder lidt. Den samlede meromkostning for landmanden er beregnet til ca. 60 øre pr kg mælk. Landmændene oplever til gengæld velfærd i staldene og arbejdsglæde ved produktionsformen.

Strategies to improve quality and safety and reduce cost of production in organic and low-input crop production systems. QLIF subproject 3: Crop production methods
Provedor de dados: Organic Eprints
Autores: Tamm, L.
Organic crop production seeks to produce high quality foods while reducing the inputs in order to promote environmental quality and conserve resources. This necessitates optimal production systems in terms of soil fertility and plant health. Studies in QLIF subproject 3 have shown that soils may gain an improved potential to release N from added amendments through adaptation of management practices. Likewise, long-term management strategies may influence suppressiveness of soils to economically important diseases. Application of manures and other organic soil fertility inputs do not pose any additional safety risk in ready-to-eat vegetables, such as head lettuce, if good farming practice is applied. Even under experimental worst-case conditions, pathogen...

Un marco conceptual para la identificación y evaluación de alternativas agroecológicas en investigación.
Provedor de dados: Organic Eprints
Autores: Tittonell, Pablo Adrián; Grazia, Javier De.
La “modernización” de la agricultura, que en Latinoamérica parece manifestarse a través de la intensificación y de la concentración de recursos productivos, lleva al establecimiento de agroecosistemas no sustentables, con graves consecuencias socio-económicas y ambientales. La investigación agroecológica permite identificar alternativas para contrarrestar tales efectos, com especial impacto en los sectores campesinos de menores recursos. Si bien no es posible hallar estrategias de aplicación universal, los principios agroecológicos básicos pueden hacerse extensivos a diversas situaciones para una mayor eficiencia en investigación. Un marco conceptual ha sido desarrollado para intentar responder: ¿Cómo se puede agrupar y sistematizar la información...

Organic dairy breeding lines? – Possibilities and Requirements
Provedor de dados: Organic Eprints
Autores: Kargo, Morten; Thomasen, Jørn Rind; Wallenbeck, Anna; Hjortø, Line; Slagboom, Margot.
Genomic breeding schemes with large cow reference populations will give room for more line division within dairy cattle breeding and therefore also for organic breeding lines. The reason is that different economic values between organic and conventional production systems are expected in the future and the existence of genotype by environment interaction will presumably be even more recognized. Therefore, correlations between organic and conventional breeding goals are expected to be significantly lower than one. This in combination with increased future “break even” correlations opens up for specific organic breeding lines.

Large variation in nitrogen efficiency among organic and non-organic farms
Provedor de dados: Organic Eprints
Autores: Hansen, Sissel; Koesling, Matthias; Schüler, Maximilian; Fystro, Gustav; Bleken, Marina Azzaroli.
Agricultural production is requested to be environmental friendly and resource efficient. A literature review of farm surveys and prototype farm studies found that increasing use of N fertilizer and imported feed increased the yields and the productivity of dairy farms, but also increased the N-surplus. We studied the N-efficiency and cause of variation in organic and non-organic commercial dairy farms.  Increased amount of purchased-N per ha farmland increased the farm N-surplus per ha on organic  and non-organic farms. Increased amount of purchased-N tended to decrease N-efficiency, but not  on non-organic farms. The correlation between the N-surplus per unit of produce and N-purchase  was weak.  The organic farms had lower N-surplus per ha than the...

Alternative Protein sources in poultry nutrition
Provedor de dados: Organic Eprints
Autores: Steenfeldt, Sanna; Lübeck, Mette; Engberg, Ricarda M.
The supply of protein and essential amino acids will undoubtedly be a great challenge for European poultry nutritionists when the transition to 100% organic feed ingredients for organic poultry production becomes reality. To avoid costly and energy consuming oversea transports connected to the import of soya beans, much research effort has focussed on the exploitation of alternative locally grown protein sources to increase the sustainability of organic production systems. Besides the cultivation of protein crops like legumes (peas, lupin, and faba been) and seeds (sunflower, rapeseed), new approaches including the feeding of protein concentrates from green biomass obtained by bio-refinement are discussed. At present, many of the alternative protein...

Combined free-range piglets and energy crop production: Impact on nitrate leaching
Provedor de dados: Organic Eprints
Autores: Lao, Emanuel Joel.
Keeping sows in the outdoor pasture conveys high risk on environmental pollution through nitrate leaching which might be tremendously high in autumn and winter. Integrating grassland based free-range pigs with selected energy crops has been proposed as one possible approach to reduce nutrient leaching; however the effect has never been quantified. The ecoefficient pig farming that takes care of pig’s animal welfare and possible reduction of nitrate loss into environment may be achieved which will contribute to the Danish Green Growth Agreement of reducing up to 19,000 tons of NO3-N between 2010 and 2015.  Apart from the main focus on NO3-N leaching potential, this experiment also investigated Nmin and phosphorus distributions at various soil depths and...

Cocoa, mainly produced by 5 to 6 millions of smallholder farmers, is considered as one of the most sustainable production system in the humid tropics. Little is known about the sustainability of different cocoa production systems.  A long-term experiment is set up in Alto Beni at 400m above sea level with a humid winter dry climate, 1’540 mm annual rainfall. The trial assesses the sustainability of five cocoa (Theobroma cacao) production systems with the parameters of yield and yield stability, input-output efficiency of nutrients and energy, soil fertility, biodiversity, economic result, climate change mitigation and adaptation. The two-factorial experiment is arranged in an completely randomised block design; the five cocoa treatments, based on local and...

Autores: Battisti, Rafael; Sentelhas, Paulo Cesar; Pilau, Felipe Gustavo; Wollmann, Cássio Arthur.
Eficiência climática (EC) é um índice que demonstra em termos quantitativos a redução produtiva ocasionada pelo déficit hídrico. Assim, este trabalho teve como objetivo avaliar a EC das culturas da soja e do trigo para o estado do Rio Grande do Sul, considerando-se diferentes locais e datas de semeaduras. A EC foi obtida pela relação entre as produtividades atingível (PA) e potencial (PPf), estimadas por meio de modelos de simulação. A PA foi obtida pela estimativa da PPf, a qual foi determinada pelo método de Zona Agroecológica da FAO, deflacionada pelo déficit hídrico em cada uma das fases das culturas para cada data de semeadura, entre os anos de 1979 e 2008. Os resultados evidenciaram que as datas de semeadura influenciam a EC para a cultura da soja, a...

Provedor de dados: Organic Eprints
Autores: Escribano, A.J.; Gaspar, P.; Escribano, M.; Mesias, F.J.; Pulido, F.
INTRODUCTION: The Spanish goat sector's crisis has led to the abandonment of a large number of farms. At present, sector's expectations are reduced, which threatens farms' permanence. This in turn means a loss of agricultural biodiversity, reduced economic activity and loss of rural population. In this context, it is necessary to implement strategies to ensure farms' continuity . In this sense, the conversion to the organic model is proposed in the farms analyzed.   METHODOLOGY: To study the possibility and feasibility of such conversion an analysis of their structure (technical and economic characteristics), an assessment of farms' sustainability (based on social, economic and environmental parameters) has been carried out. For this purpose, the MESMIS...

Kurzumtriebsplantagen als Landnutzungsoption auf vernässtem Grünland und Niedermoorrandgebieten?
Provedor de dados: Organic Eprints
Autores: Koim, Nora; Murach, Dieter.
Short rotation coppice (SRC) of willow variety ‘Tordis’ and poplar variety ‘Max 1’  were established on two grassland trial sites featuring elevated and changing groundwater tables in order to investigate if they offer land users a valid alternative to annual cultivation which often requires continually soil draining on such sites. Using a low-impact planting technique in order to preserve soil carbon storage, ploughing and heavy machinery were avoided, and neither herbicides nor fertilizers were applied. Initial growth was slow in both varieties due to competition for light in dense grass cover. In later growth, the differences between the growth performance of willow and poplar increased. At the two sites (A and B), willow achieved 5.3 m (A) and 3.2 m...

Mindre sygdom i økologisk dyrkede kepaløg
Provedor de dados: Organic Eprints
Autores: Fruekilde, Anne Mette; Bjørn, Gitte.
Sammenlignende forsøg med sorter af kepaløg dyrket økologisk og konventionelt viser væsentligt lavere udbytte i de økologiske løg, i gennemsnit 44% lavere totaludbytte. Det er sansynligvis især problemer omkring etablering der er årsag til det lavere udbytte, bl.a. var plantetallet klart mindst i de økologiske løg, men enkeltløgene var dog også mindre. Samtidig viser resultaterne dog også, at der er mindre sygdom i de økologiske løg, og dermed en lavere frasortering inden salg. Difference i salgbart udbytte (39%) er derfor mindre end ved sammenligning af totaludbytterne.

Provedor de dados: Organic Eprints
Autores: Klarer, F.; Stöger, E.; Bubenhofer, R.; Walkenhorst, M.; Meier, B.
Introduction: In Switzerland, the administration of medicinal plants to livestock is almost completely confined to the use of home remedies. To save this traditional knowledge, which has been handed down through word of mouth, a project aims to collect this information from different regions of Switzerland. Grison home remedies have been evaluated to decide whether or not they can be recommended.  Methods: 32 current or former Grison livestock keepers (average age 59 years) provided information on the home remedies they use or have used to maintain the health of their cattle, sheep, goats, pigs and horses and to treat them. The data collection was conducted by interview (28 on-site, 3 by phone, 1 in writing) with a standardised questionnaire about...

Provedor de dados: Organic Eprints
Autores: Aanensen, Lise; Henriksen, Britt I. F.
På oppdrag fra Relelverksutvalget for økologisk produksjon (RVU) har Bioforsk utført en vurdering av fordeler og ulemper knyttet til luftekravet for okser i økologisk produksjon, samt en utredning av mulige løsninger for lufting av okser. I tillegg er det utført en vudering av alternative metoder for produksjon av økologisk storfekjøtt, for eksempel produksjon av kastrat-, kvige- og kalvekjøtt. Økologisk produksjon av storfekjøtt er vurdert med bakgrunn i kravet om lufting av okser. Regelverket for økologisk produksjon(EU-reg. 2091/92) sier at "(...) okser skal ha tilgang til beiter eller luftegårder. Okser over ett år gamle kan holdes i et husdyrrom med fri adgang til en luftegård hele året, i stedet for å gå på beite i sommerperioden." Nytt regelverk som...

Production Efficiency and Diversification in Mexican Coffee-Producing Districts
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Vedenov,   Dmitry V.; Houston,   Jack E.; Cardenas,   Gabriela.
Coffee production system is analyzed for 24 municipios (districts) in Veracruz, Mexico, from 1997 to 2002.  A stochastic frontier approach is used to estimate an input distance function and to evaluate production efficiency.  Results show the production process to be stable over time despite global price fluctuations.  Production of staple crop (corn) with either coffee or other cash crops results in increased efficiency as a result of the economies of complementarity, while production of coffee with other cash crops leads to lower efficiency.  Factors contributing to higher efficiency included higher population density, road availability, and higher altitude, typically associated with production of higher-quality coffee.

Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Seecharan,   Denny; Jacque,   Andrew Eliel.
Rice imports into Trinidad and Tobago in 2005 represented approximately 95% of domestic demand. Local production has been declining since reaching a peak of 21,000 tonnes in 1992.  Present production is 3,500 tonnes.  Rice is produced under a variety of production systems and on farms of varying sizes, productivity and quality of output.  This paper examines the competitiveness of four production systems used in Trinidad and Tobago, viz.: the transplanting system (ST), the broadcast seeded system (SB)(both being small farms and highly labour intensive), the partially mechanized system of medium sized farms (MM) and a fully mechanized large farm utilizing aerial technology in the production system (CRP).  The methodology involved the collection of data on...

Using 'Inclusive Wealth' to Measure and Model Sustainable Development in Australia: A working example
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Harris,   Michael; Pearson,   Leonie J.
Australia in 1992 adopted the National Strategy for Ecologically Sustainable Development to ensure all future development occurs in a 'sustainable' manner. Measurement of the nation's sustainable development is currently conducted through the OECD Environmental Performance Review and various other ad-hoc indicators or measures have been proposed, such as greening the national accounts (Green Gross National Product) and the Genuine Progress Indicator. No one has identified a clear and precise way to either measure or model sustainable development in Australia. By trialing the implementation of inclusive wealth theory in Australia, this paper aims to identify and comment on the issues of measuring and modelling sustainable development as a stock measure in...

Autores: Pruitt,   J. Ross; Gillespie,   Jeffrey M.; Nehring,   Richard F.; Qushim,   Berdikul.
Using USDA’s Agricultural Resource Management Survey data, factors leading to the adoption of technology, management practices, and production systems by U.S. beef cow-calf producers are analyzed. Binary logit regression models are used to determine impacts of vertical integration; region of the U.S.; farm size, diversification, and tenure; and demographics on adoption decisions. Significant differences were found in adoption rates by region of the U.S., degree of vertical integration, and size of operation, suggesting the presence of economies of size and vertical economies of scope. Results also indicate high degrees of complementarity among technologies, management practices, and production systems.

Technical efficiency and technology gaps in beef cattle production systems in Kenya: A stochastic metafrontier analysis
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Otieno,   David Jakinda; Hubbard,   Lionel J.; Ruto,   Eric.
In this study the stochastic metafrontier method is used to investigate technical efficiency and technology gaps across three main beef cattle production systems in Kenya. Results show that there is significant inefficiency in nomadic and agro-pastoral systems. Further, in contrast with ranches, these two systems were found to have lower technology gap ratios. The average pooled technical efficiency was estimated to be 0.69, which suggests that there is considerable scope to improve beef production in Kenya

Energy balance methodology and modeling of supplementary forage production for cattle in Brazil
Provedor de dados: Scientia Agricola
Autores: Romanelli,Thiago Libório; Milan,Marcos.
Cattle is the main protein source in Brazil and cattle production depends on preserving forage in order to decrease the influence of dry periods on grass production. To minimize such problems, some new techniques have been created to increase the yield which also leads to energy demand increase. Energy balance is a vital tool to evaluate the efficiency of energy consumption in production systems. There is no standard methodology established for this determination. It is also difficult to analyze different management options because of the complexity of the production systems and the interactions among variables. Therefore the purpose of this study is to develop a methodology that supports the development of a model, using a spreadsheet, and to use it to...

Abstract The objective of the present study was to characterize maize silage according to chemical composition, maize silage yield, as well as their predicted milk production. A search was made on studies related to maize silage yield, density, chemical composition (DM, CP, NDF, starch), and dry matter digestibility (DMD). In this study, 41 maize varieties from temperate regions and 101 maize varieties from tropical origin were analyzed. The net energy of lactation (NEL Mcal/kg DM), kilograms of milk per t of silage (kg of milk/t DM), and kilograms of milk per hectare of silage (kg of milk/ha) were determined. A cluster (CL) analysis was performed, and six CL of maize silage were obtained. The CL1 included digestibility for dry matter, crude protein,...

Carcass characteristics and chemical composition of Longissimus muscle of 32 young bulls from four genetic groups slaughtered at 14 months old were evaluated. Experimental design was completely randomized and distributed into four genetics groups: 1. Caracu (CAR); 2. Canchin (CAN); 3. Charolais vs. Caracu (CHC) and 4. Aberdeen Angus vs. Canchin (AAC). Carcass dressing and carcass conformation were lower for CAR than CAN, CHC and AAC genetic groups. No difference has been reported with regard to moisture, ash, crude protein, total lipids and total cholesterol among four genetics groups. The genetic groups influence fatty acid profile on Longissimus muscle in bulls. Cattle with zebu genes had the highest rates in unsaturated fatty acids, saturated fatty...

Improving the yield of rice (Oryza sativa L) in existing irrigated areas rather than further expansion is more likely to be the main source of growth for the crop in Kenya, especially due to limited land and water resources. In order to achieve this, there is need to identify and adopt solutions that are environmentally more sustainable. That is, the production systems adopted should reduce water consumption and increase productivity. This study evaluated whether the System of Rice Intensification (SRI) could increase water use efficiency and crop productivity relative to the conventional production system of continuous flooding. The effects of SRI on total water input and the growth characteristics of three rice varieties were investigated in a split-plot...

Artisanal fishing on the northern coast of Brazil is characterized by a set of different fishery modalities. Using a multidisciplinary approach, 20 fishery production systems were identified, with distinct characteristics regarding technology and purpose. The characteristics of each system were classified into five dimensions (ecological, economic, social, technological and political). Multidimensional scaling revealed that some of these 20 systems have greater similarities. Thus, a total of 10 groups were identified.

Provedor de dados: Brazilian Archives of Biology and Technology
Autores: Santos Neto,José dos; Schwan-Estrada,Kátia Regina Freitas; Sena,José Ozinaldo Alves de; Telles,Tiago Santos.
ABSTRACT The aim of the present study is to evaluate the economic viability of tomato cultivation in a system of organic farming, and to compare it with the conventional farming system. The fixed and variable costs of both cultivation systems were calculated, as well as the costs of disease control with the application of alternative products and pesticides. The revenues were computed using commercial production and the direct sales price. The total cost per area was higher in the conventional system, while the cost per plant was greater in the organic system, since it used a lower plant population density. In the conventional system, 2.33 times more was spent on plant management, due to the fact that the number of sprayings was greater than that carried...

Autores: Schnettler M,Berta; Silva F,Roberto; Sepúlveda B,Néstor.
Credence attributes (production system, animal welfare, traceability, among others) have acquired importance for meat products in developed countries, representing information that must be included on label. A personal survey was administered to 770 consumers in the Bío-Bío and La Araucanía Regions, Chile, to determine the utility of information contained on the label and acceptance of information referred to as credence attributes, as well as to distinguish different consumer segments. The packaging and expiry dates were the most useful aspects of the current information. The greatest degree of agreement with respect to information that should be included was a quality seal, type of animal, handling regarding animal welfare, production system and feeding....
