Abstract

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.

Nitrogen losses
Nitrogen (N) management is commonly defined as 'a coherent set of activities related to the allocation and handling of N in agriculture to achieve agronomic and environmental/ecological objectives' (e.g. Oenema and Pietrzak, 2002). Common agronomic objectives relate to crop yield, crop quality and animal performance, while environmental/ecological objectives commonly relate to minimizing N losses and to increasing N use efficiency (NUE). The objectives of N management are often region-, watershed-, site-, farm-, and/or field- specific. Nitrogen management is evaluated successful when objectives are achieved. Economic costs and associated risks of N management measures are often seen as an obstacle and/or delay for implementing such measures in practice (Sheriff, 2005; Oenema et al., 2011a). Indeed, management measures require additional activities and possible changes in practices, which cost money. Thereby the competitiveness of the farms may decrease. In an open, globalized market, it is necessary to establish a level playing field; otherwise producers will remain reluctant to fully implement measures that put them at a comparative disadvantage. However, there is surprisingly little empirical information about the cost and benefits of improved N management. The objective of this paper is to review available literature, which relates to developed countries.
