Farm N balances in European landscapes and the effect of measures to reduce N-losses

The farm gate N balance is acknowledged as a valid and reliable indicator for potential nitrogen losses from agricultural systems, and the main driver for N pollution from intensive agricultural landscapes (Dalgaard et al., 2011a). Consequently, to investigate potentials for the reduction of Nlosses and greenhouse gas emissions, farm N balances from study landscapes in Denmark, France, Poland, Scotland, The Netherlands and Italy was collected during the www.NitroEurope.eu research project, and the remarkable differences between both the levels of-, and the within landscape heterogeneity were further investigated.
