This study investigates the N transfer from legumes to neighbouring plants, grasses, legumes and herbs in a temperate grassland. In a field experiment white clover (Trifolium repens), red clover (Trifolium pratense) and lucerne (Medicago sativa) were leaf-labelled with 15N enriched urea. The 15N tracer was measured in above-ground plant tissue of eight neighbouring plants in two subsequent harvests in 2008. The three legumes donated 15N to all neighbouring plants, of which grasses, white and red clover were strong receivers. Results show that N transfer increases with N application and from the 1st to the 2nd cut. |

O presente artigo é uma revisão de literatura elaborada a partir de uma olhar sobre os reflexos da política de modernização agrária na Amazônia no sistema tradicional de uso da terra de agricultores familiares da comunidade São João onde foram implantados sistemas agroflorestais (SAF´s) através do projeto Raízes da Terra. A metodologia utilizada mesclou abordagens quantitativas e qualitativas com a realização de entrevistas, questionários, observações e revisão de literatura em um estudo de caso constituído por 15 famílias de agricultores. As principais conclusões mostram que a implantação de SAF´s foi uma proposta idealizada e organizada por agentes externos à comunidade São João e conhecedores da realidade local, que através do projeto Raízes da Terra,... |

Ersöz, Vehbi. |
Farming since 1983, Vehbi Ersoz always thought there were some problems with the conventional farming methods. Using a different pesticide for each varmint and a different fertilizer for each missing substance in the soil made him question the function and procedures in conventional agriculture. Favoring a more holistic perspective in agriculture, he tried many methods to enrich the soil and increase the soil microorganisms, which in turn do the actual work. In his region he brought many leading and innovative techniques to life. Some of them are greenhouse farming, organic farming, biodynamic agriculture and Shumei method of agriculture. As a side benefit of applying many different techniques, he discovered that methods applied in one philosophy, may in... |

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

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

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... |

The prairie ecosystem that occupied most of the North American continent has been mostly converted into agricultural farmland. The looming global scarcity of fossil fuels has spurred interest in producing ethanol from corn (Zea mays) but legitimate objections remain to the idea of supporting this vision. The purpose of this study was to initiate a prairie restoration on marginal soil of a 16.2 ha. farm in southeastern Minnesota and to determine which restoration procedure (only native grass species versus a mixture of grasses and forbes) was most effective for the establishment of prairie on the land that may yield biomass for biofuels. We planted 11.4Kg./ha. of grasses on 4.7 ha. and 0.70Kg./ha. of forbs on 3.2 ha., in June 2007. An evaluation of... |

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

Deze brochure geeft praktische tips over de aanleg en het beheer van akkerranden. Akkerranden zijn functioneel op het landbouwbedrijf omdat ze schuilplaatsen, overwinteringsplekken en voedsel bieden voor nuttige insecten die helpen bij de plaagbeheersing. Akkerrandenbeheer past binnen geïntegreerde plaagbeheersing op het akkerbouwbedrijf maar in de praktijk lopen veel telers tegen praktische problemen aan. De ervaringen zijn daarom gebundeld in deze brochure met de do’s en don’ts voor akkerrandenbeheer. |
