An EU-financed project (AIR3-CT93-0852): ťOn-farm development of organic farming systems: the role of livestock and agro-forestryŤ links five European institutions. There are two tasks: (A) On farm research and farmer participation to increase the potential for organic production in regions where there are limited viable livestock enterprises and/or where it is necessary to protect sensitive mediterranean environments, (B) Detailed study to improve nutrient supply and weed control systems for organic arable crops.

The goal of Task A is to develop a basic farm model including: a) Rotation and fertilization strategy, designed to minimize the loss and optimize the efficient use of nutrients; b) Pest, disease and weed management strategies through crop rotation and crop husbandry; c) Establishment and development of an ecological infrastructure. Four objectives were fixed: A1) Conversion and farm design adapted to specific regions in Spain, Greece and France (FR), A2) Weed control, A3) Nutrient supply, A4) Plant extracts effects on various crops (DE).

Task B involves detailed trials on weed control and nutrient supply with two objectives: (B1) Evaluation of weed populations and crop competitiveness to aid prediction of timing of mechanical weed control in organic systems (GB) and (B2) Management of nutrient supply through crop rotation and/or the use of supplementary nutrient sources.
