Soil erosion on agricultural land in Slovenia - Measurements of rill erosion in the Besnica valley

Abstract

The article describes soil erosion in Slovenia. There is little concrete data on soil erosion due to the lack of awareness of this process and the fragmentation of farmland. Long-term measurements of soil erosion have only been done at one location; elsewhere, there have only been short observations and calculations and modeling on the basis of empirical equations. To increase our knowledge of this phenomenon, we took measurements of soil erosion on a field in the Besnica Valley northwest of Kranj. With the decrease of agricultural land use in Slovenia due to natural, social, and economic factors, the amount of material lost to erosion has decreased in the last few decades. For protection from erosion, various preventive methods such as terracing, mulching, and contour plowing are employed. The awareness that protection against erosion is a demanding and long-term task is gradually increasing, but nothing can replace the soil that has been lost due to erosion.
