Geostatistical model evaluation for soil tillage suitability on Osijek-Baranya County example

This paper presents a computer model to determine land suitability for soil tillage in eastern Croatian based on geostatistical analysis of soil data. As the basis and source of soil types data was used the Croatian soil suitability map in digital form from which used data of soil types and soil chemical analysis data from the interpretative database fertility control of Osijek-Baranja County, a total of 17 341 samples of soil. Presents the model evaluation arable land workability uses a 6 indicators benefits of which three were identified accurately (pH, humus and elevation), and the remaining three are based on Digital Soil Map of Croatian and pedosystemic units whose inherent properties are ranked relative to particular indicators of suitability for soil tillage. Computer simulation using the described models and kriging geostatistical method obtained results showed that 66% of agricultural land belongs to the class of limited suitability for soil tillage (P3), approximately 21% is moderate and very convenient (P2 and P1), and only ~13% belong to the temporary or permanently unsuitable for soil tillage.
