Summary

One of the problems in the Baltic Sea region environment is the reduction of surface water pollution by nutrients. Monitoring shows that in spite of significant decreasing of fertilizers in Estonia the nitrogen concentrations tend to increase in some water bodies. Increasing trends may be observed even in the watersheds with very low human activity. Some authors say that it may be due to processes going in drained peat soils (mineralization of organic matters and leaching of nutrients). In current study, described in this paper, the two models SOIL and SOILN, developed for small fields, were used on the watershed scale to model nitrogen transport. The approach was successfully tested on two watersheds (with areas 79 and 481 square kilometers).
