The Weser River Basin will most likely not meet European water framework directive nitrogen concentration targets by 2015. We use the AGRUM model network connecting hydrological and nutrient transport models with a German agricultural sector model to analyse current and future nitrogen surplus...

Agriculture is to a large part responsible for nitrate leaching into groundwater and rivers in Germany, especially in highly intensive agricultural regions. To evaluate the link between nitrogen surpluses from agriculture and nutrient leaching into ground- and surface waters, a model network to...
