Abstract: In this study, the Soil and Water Assessment Tool (SWAT) was extended with algorithms from a detailed nitrogen turnover model to enhance the model performance with regard to the prediction of nitrogen leaching. The new model, which is further referred to as SWAT-N, includes algorithms for decomposition, growth of nitrifying bacteria, nitrification, nitrificatory as well as denitrificatory N-emissions, N-uptake by plants and N transport due to water fluxes. The model was tested with a lysimeter dataset of a long term fertilisation experiment including crop rotation conducted in Eastern Germany.
