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

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

| O comportamento de vacas leiteiras pode ser influenciado pela natureza do tratamento que recebem dos humanos. Neste trabalho foram comparados 20 estabelecimentos de agricultores familiares que usavam terapia convencional (n=11) ou homeopática (n=9) como principal terapêutica em rebanhos leiteiros. Foram feitas entrevistas com os agricultores, medidas de comportamento humano (como nomear e falar com os animais, contatos positivos ou negativos, condução para a sala de ordenha), e de comportamento animal. Foram encontrados escores de comportamento humano similares entre os dois grupos. A média de distância de fuga foi menor nos rebanhos sob uso de homeopatia do que no convencional (P=0,04). Nos 9 estabelecimentos homeopáticos o medicamento era colocado na... |

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

| Background: Stable soil aggregates are essential for optimal crop growth and preventing soil erosion. However, tillage is often used in agriculture to loosen the soil, which disrupts the integrity of these aggregates. Soil aggregation can be enhanced by bacteria through their ability to produce exopolysaccharides and lipopolysaccharides. These compounds stabilize soil aggregates by “gluing” soil particles together. However, it has yet to be shown how tillage influences the bacterial potential to produce aggregate-stabilizing agents. Therefore, we sampled conventional and reduced tillage treatments at 0–10 cm, 10–20 cm and 20–50 cm from a long-term field trial in Frick, Switzerland. We compared the stable aggregate fraction of the soil and the bacterial... |

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

| This paper shows that general trust in the organic label as well as perceived positive health effects of eating organic products have positive causal effects on actual organic consumption. The data used is panel data for 830 households reporting actual purchases together with responding to a comprehensive concerning questionnaire attitudes in 2002 and 2007. The paper also shows that perceived positive environmental effects and perceived better animal welfare related to organic production have no significant effect on actual behaviour, whereas concern for artificial additives and low price sensitivity increases the organic budget share. Surprisingly enough, households who worry about GMO or pesticides do not seem to have a higher propensity to purchase... |

| This paper aims to perform a meta-analysis of the literature comparing the environmental impacts of organic and conventional farming and linking these to differences in management practises. The studied environmental impacts are related to land use efficiency, organic matter content in the soil, nitrate and phosphate leaching to the water system, greenhouse gas emissions and biodiversity. The theoretic framework uses the driver-state-response framework and literature data were analysed using meta-analysis methodology. Meta-analysis is the statistical analysis of multiple study results. Data were obtained by screening peer reviewed literature. From the paper’s meta-analysis it can conclude that soils in organic farming systems have on average a higher... |

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

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

| The control of perennial weeds in organic crop production needs reconsideration to minimise losses of nutrients through leaching. Long post-harvest periods with mechanical weed control hinder a plant cover with the purpose of taking up nutrients not being utilised by the main crop to maintain soil fertility. To meet the interests of nutrient and weed management, we suggest a new concept for the control of perennial weeds with propagules placed within the plough layer. The concept comprises uprooting and immediate removal of Elytrigia repens rhizomes with modified machinery to allow for a quick re-establishment of a plant cover to avoid longer periods of bare soil. Four passes with a modified cultivator where each pass was followed by rhizome removal and... |

| A new arbuscular mycorrhizal, Paraglomus-like, fungal species (Glomeromycotina) was found and propagated in single-species cultures established from spores coming from Oman, Greece, Tunisia, and New Caledonia. The hyaline spores of the fungus are small, 17–67 μm diam. when globose. Their spore wall consists of an evanescent, 1.0–2.3 μm thick, short-lived outer layer and a laminate, smooth, 3.8–7.3 μm thick inner layer, of which none shows amyloid or dextrinoid reaction in Melzer's reagent. Mycorrhizal structures (arbuscules and hyphae without vesicles) of the fungus stained slightly in Trypan blue, thus like those of the formerly described Paraglomus spp., in which the histochemical feature has been recognized. However, in the phylogenies gained from... |

| Phylogenetic analyses of sequences of the SSU–ITS–LSU nrDNA segment and the RPB1 gene showed that the arbuscular mycorrhizal fungus originally described as Diversispora omaniana does not belong to the genus Diversispora, but represents a separate clade at the rank of genus in the family Diversisporaceae of the order Diversisporales. The closest natural relatives of the fungus proved to be species of the genera Corymbiglomus and Redeckera. Consequently, the new genus was named Desertispora, and Di. omaniana was renamed De. omaniana comb. nov. In addition, the morphological and histochemical features of spores and mycorrhizal structures of a new Diversispora sp., Di. sabulosa, were described and the closest relatives of the species were determined based on... |

| An original and integrative evaluation indicator has been developed to quantify the cumulated damage from major pests and diseases affecting grape bunches: downy mildew, powdery mildew, gray mould and tortricid moths. It made it possible to estimate the associated crop losses and to relate them to the plant protection strategy in different modes of production (organic farming, in-transition, conventional). Thus, overall plant losses were higher in 2012 than in 2011. The in-transition growers’ strategy, with reduced copper doses but increased numbers of sprays, led to a 20% increase in average severity on bunches (essentially due to Downy mildew). The more pragmatic approach of experienced organic growers and conventional ones (higher doses and fewer... |
