Abstract: 

Process based modelling of nitrogen turnover and transport is mainly focused on the plot and field scale. However, scaling up to the landscape level with sufficient topographic gradient and conductivities, Nr is relocated in the landscape through surface runoff, interflow as well as lateral groundwater movement. Cause and effects of NrApproach can therefore be spatially disaggregated, i.e. leached Nr applied uphill on agricultural land can for example lead to gaseous N emissions downhill in riparian plains. In the Danish NitroEurope study landscape, lateral translocation of dissolved nitrogen due to the hydrogeological conditions is likely and indicated by spatially differing concentrations of Nr in the stream water under comparable land use practices.
