| Earthworm proliferations of 57–122% (mean +78.5%) under adjacent (i.e., same soil/climate) organic vs. conventional fields related to improved soil quality and higher yields of 16–80% (mean +39.1%) in winter wheat, tropical paddy rice and sugarcane. Soil moisture differences ranged -11–41% (mean +12.0%) while soil carbon in SOM humus ranged 26–128% (mean +64.9%). Correlation (r >0.835) of earthworms is with crop yield and both soil H2O & C storage hence atmospheric CO2 reduction via photosynthesis / humification. A 1,000 yr-old pasture at Haughley had highest earthworms (424 m-2), stored 222 t ha-1 carbon in its soil organic matter (SOM), plus moisture capacity was 90.9% above an adjacent arable field. Relating to global climate change,... |

| The main aim of OK-net Arable project is to make available tools that facilitate exchange of knowledge and promote co-production of knowledge relevant for farmers to help them improve organic arable cropping. This report is the main outcome of task 3.3 of the project. The goal of this task was to identify criteria for relevant end-user and education material, select the best materials among those already available and develop new material, based on state-of-the-art research results and best practices (deliverable D3.1) and the recommended methods and tools for knowledge exchange (deliverable D3.2) in each of the thematic areas important for organic arable farmers (soil quality & fertility, nutrient management, weed control, pest & disease control... |

| Introduction Most agricultural operations, such as soil tillage, manuring, grazing, and irrigation, pose a serious threat to water quality. Agriculture is a heavy water user and a serious water polluter (nutrients, pesticides, salts, pathogens, heavy metals, oxygen-depleting and radioactive substances, etc.). In addition, agriculture threatens water habitats. The UN “Convention for the Protection and Use of Transboundary Watercourses and International Lakes” ratified at Helsinki in 1992 obliges the signatory countries to further prevent, control and reduce water pollution from point and non-point sources. The implementation of the Convention is co-ordinated by the UN Economic Commission for Europe. In October 1999, this organisation commissioned a study... |

| Intensive mechanical soil cultivation and herbicide treatment was often the preferred technology in vineyards in the second half of the 20th century. In the last decades we increasingly experienced the disadvantages of these technologies: soil degradation, erosion and deflation damages. The use of well-adapted cover-crop mixtures could be an alternative. In 2012 we started to study three different species-rich cover crop mixtures (Biocont-Ecovin, Legume mixture, Grass-herb mixture) in Hungarian vineyards. For 2013 we detected lower weed coverage in the inter-rows sown with the Grass-herb and Legume mixtures, while in control and Biocont-Ecovin inter-rows we detected increasing weed coverage. In the third year (2014) we found in case of every plot that... |

| The development and promotion of improved crop varieties as well as efficient seed production, distribution, and marketing systems have contributed significantly to increased agricultural production and food security in Kenya. However, these impacts have not been replicated in the semi-arid midlands due to climatic, soil, and institutional factors. Following the liberalization of agriculture in the late 1980s, there has been greater participation of the private sector, non-governmental organizations, and voluntary agencies in the area. This study examined the extent to which these developments affected farmers’ access to dryland crops. The study found that the low quantity of seed traded, high cost of production, and high seed supply prices constrained the... |

| This paper examines current situation in Russian agricultural and food sector and evaluates forthcoming development. Russia's agricultural production diminished by half at the beginning of the 1990s, and since that the production has hardly grown. In fact, Russia is one of the biggest food importers in the world. Particularly in livestock sector the situation is difficult. Number of livestock has not grown according to expectations and production does not satisfy domestic demand. Crop husbandry, by contrast, has export potential, but fluctuations in export volumes have been great. Furthermore, quality of grain has not always met standards. Russia's food industry has grown rapidly in the past few years, even though Russia has not reached self-sufficiency.... |
