The intensity of land use and the level of crop fertilisation in south-eastern and eastern European countries differ from the western European countries. In south-eastern and eastern European (EE) countries lower doses of mineral fertilisers are usually applied while the nutrient ratio is highly unbalanced (much higher proportion of nitrogen to phosphorus and potassium is used), and the input of nutrients in organic form is lower. Adequate fertilization regimes, maintenance of nutrient balance in soil-plant system and land use practices that would bring high agricultural production and reduce the impacts of agriculture on the environment need to gain more understanding in EE countries. Common to many of the EE former communist countries are agriculture systems based on collective farming with all problems that such a management system can bring - inefficiency of agriculture production, wrong use of fertilizers, no respect for the environment. Particularly, the optimal use of nitrogen and phosphorus fertilizers is important due to possible N and P leaching to ground and surface waters and the risk of water eutrophication. The other problem that will be addressed is the high losses of base cations from the land to waters and the resulting acidification of soils.The proposed project will contribute to the exchange of best practices in nutrient management - efficient use of nutrients (N, P, K, Mg, Ca, S,…) from applied fertilisers to achieve highest possible crop production and simultaneously reduced negative impact on the environment (nutrient losses). The mutual exchange of knowledge and experience will be focused on the following topics: (i) nutrients cycling in agroecosystems and comparison of analytical methods used in partner countries for nutrient determination and their efficiency; (ii) environmental impacts of land use (nutrient losses & acidification of soil & eutrophication of water); (iii) conventional and organic farming (nutrient use efficiency).The project will benefit partner organisations in research (improve local management fertilization tools) and training area (enhanced research and education system at universities) and simultaneously will be used to transfer the new knowledge to extension services (farmer advisory systems and farmers). Through the improved farming practices, efficient use of fertilisers and reduced impact on the environment, the socio-economic situation and development of rural areas in the partner EE countries will be improved.
