Summary

The objectives of this study were to quantify fluxes and balances of N, P, K, Cu and Zn in two organic fattening pig outdoor systems, to quantify the load of nutrients in different sub-areas through behavioural studies of defecation and urination and to make an environmental risk assessment. The study forms part of a larger project with the aim of identifying a joint strategy. The outdoor area balance was calculated for N, P, K, Cu and Zn. Total calculated amounts of N, P, K, Cu and Zn in manure were distributed between outdoor sub-areas according to ratios determined in behavioural studies of defecation and urination and by manure mapping. Some proposals for improving the nutrient management and decreasing the negative environmental impact in different outdoor systems are discussed.
