It is generally accepted that changes in agricultural management during the last decades have had negative effects in the forms of increased erosion and nutrient losses. In our analysis farmers are assumed to maximize expected profits. Economic incentives or direct regulations of agronomic practices may be used to change the farmers' management into a direction that will reduce the losses of nutrients and erosion. In an interdisciplinary research project with economists and ecologists, the effect of different policy measureson erosion and nutrient losses has been analysed. Policy measures analysed were, among others, catch crop requirements and subsidies for spring ploughing instead of autumn ploughing. First, an economic decision making model was ran for farms for a period of 20 years. The model decides the agronomic practice for each year on the different fields for a set of model farms. With the newly developed erosion model, the European soil erosion model (EUROSEM), the effect of the different agricultural practices were analysednot only at the level of single model farms, but also at the landscape level by use of a terrain model.
