Abstract

Soil and terrain properties are the most important environmental elements for char- acterization of within-field variability supporting the management zone definition. This study aims to develop a digital soil mapping approach to map texture related soil property, namely soil plasticity (Ka) using georeferenced machinery data derived from log file created along soil-tillage activities. The results indicated that speed and distance values have the highest correlation with Ka, having values around 0.4–0.5. The development of the regression model resulted in an adjusted R2 value of 0.71, but the p-value was still around 0.2. These results indicate that the approach has a good potential, but statistics need to be improved with data preprocessing.
