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 nitrogenlosses from agricultural systems, and the main driver for N pollution from intensive agriculturallandscapes (Dalgaard et al., 2011a). Consequently, to investigate potentials for the reduction of Nlossesand 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 researchproject, and the remarkable differences between both the levels of-, and the within landscapeheterogeneity were further investigated.
