A statistical developed yield matrix which combine different arabie crops and grassland types with 56 different types of agricultural sites is the bas is for natura/ yield estimation. This yield matrix was combined with additional model approaches dependent on different site charcterisics, weather/climate, plant breeding, and agromanagement information, among them with fuzzy approaches for different nitrogen fertilization and plant protection levels. The integrated assessment of regional crop coverage is realized as the degree of crop coverage taken from (O, 1) using crop-specific stepwise temperature sumfunctions. The regionalization ofyield estimation and crop coverage models is realized by model integration into the Spatial Analysis and Modeling Tool (SAMT). The models are applied to the Qui/low catchment located in the Uckermark region, Germany. Spatial results,are presented and discussed.
