Abstract

Proper identification of erosion processes is possible by a combination of the presented methods. The importance is in exact localization of areas endangered by the erosion with the possibility of designing exact anti-erosion protection. The method of visual identification, verification of erosion processes by soil probes and identification of soil organic matter and soil structure were used. Significant soil loss caused by water erosion has become a global problem. An effective solution of this problem is conditioned by the effective identification of areas under threat of water erosion, which prevails in Slovakia. The aim is to point out the need to combine methods of identification of water erosion processes in order to objectify them for the needs of elimination of water erosion in agricultural practice. For water erosion assessment we used the method of spatial extension and digitisation of surface water erosion results using aerial photographs and modelling of water erosion processes using the universal equation for calculating the loss of soil by water erosion.

Keywords: erosion process, modelling of water erosion, soil probe, soil organic matter, anti-erosion soil protection
