In the years 2013 and 2014 excavations of soil probes and soil samples were carried out on 14 plots. Areas damaged by water erosion with soil type of chernozem were selected. The results of bulk density and total porosity confirmed the compaction of the soil with the worst results at the foot of the slope and in the subsoil. High values of maximum capillary capacity and low values of minimum air capacity indicate a violation of soil structure. The loess covers in the middle of the slope come into contact with precipitation water and agricultural machinery and change in physical properties occures. The decrease in carbonate content in the loess caused by erosion was found in the middle part of the slope and at the point of accumulation. Humus content, as well as phosphorus and potassium content, is significantly reduced due to erosion in the middle part of the slope. It has been confirmed that water erosion has a negative impact on a variety of soil properties, even in the profile depth, and worsens the conditions for good plant growth.
