| Organic farming systems need to replace nutrients exported via farm products, especially phosphorus (P) which may otherwise become depleted in soil in the long term. In Europe, EU regulations for organic production are shaping the farming systems with respect to inputs of nutrients. Permitted off-farm P sources include conventional animal manure, composted or anaerobically digested organic residues, rock phosphate, and some animal residues such as meat and bone meal. The recent proposed revision of EU regulations for organic production (2014) puts less emphasis on closing nutrient cycles and instead aims at minimizing off-farm inputs, to reduce the risk of importing contaminants. This development, which has received little attention from the organic sector... |

| Organic farming systems rely on the efficient use anrecycling of resources. Currently, nutrients like phosphorus (P) are used only once to produce food and subsequently, lost due to poor recycling. Current regulations concerning the use of alternative P fertilizers are strict, restricting e.g. the use of municipal organic wastes and hampering e.g. the use of sewage sludge due to concerns about heavy metals and other pollutants. However, there is an urgent need to improve the recycling of P from urban areas back to cropland, as the worldwide P reserves are very limited. Furthermore, improvement of agronomic P efficiency due to the choice of P efficie cultivars and agronomic methods (e.g. P mobilization by cover cropping, application of microorganisms suited... |

| Organic farmers adhere to high standards in producing quality food while protecting the environment. However, organic farming needs to improve continuously to keep meeting its ambitious objectives. The project ‘Replacement of Contentious Inputs in Organic Farming Systems’ (RELACS) will foster the development and adoption of cost-efficient and environmentally safe tools and technologies to further reduce the use of external inputs on organic farms across Europe as well as in Non EU Mediterranean countries. Project partners will provide scientific support to develop fair and implementable EU rules to improve current practices in organic farming. Farm advisory networks in 11 European countries will reach out to farmers to ensure effective dissemination and... |
