Relative Soil Suitability Assessment (R.S.S.A.) Model for Crops

During the seven-year period of research, 13, 085 samples of soil have been collected in East Croatia. Using the gained soil information, eight indicators which influence relative soils suitability assessment for crops have been singled out. While taking into account the natural laws of selected indicators and, an expert model which describes every indicator via functions has been created. The model was conceived as a tool that could be changed very easily, that is, adapted to various crops and agroecological conditions. Minimal estimated relative soil suitability assessment by Relative Soil Suitability Assessment (R.S.S.A.) model was 34.4%, and maximal was 95.2%. The largest sample number, 7, 768 of them, was located in the moderately suitable class. On the example of Osijek- Baranja County, the model has proved itself to be precise in comparison to the real situation in the field. Also, by implementing the geostatistical method of kriging, a prediction of the production area has been done, and with the maps that have been created through this method, we can easily use to detect problematic agricultural areas.
