Abstract
Soil erosion is one of the biggest environmental and economic problems of agriculture in Ukraine. Significant losses of topsoil due to water and wind erosion lead to reduced yields, depletion of land resources and economic losses estimated at hundreds of millions of dollars annually. For effective management of soil resources, it is necessary to have accurate forecasts of erosion processes. This study used the Universal Soil Loss Equation (USLE) mathematical model, which allows estimating the average annual soil loss due to water erosion. The study was conducted in the Rohanska territorial community of Kharkiv region, where agricultural land occupies 65% of the area. Analysis of the results showed that a significant part of the community has an erosion hazard level exceeding the permissible limits. Erosion hazard maps constructed on the basis of modeling can be used to plan effective soil protection measures, adapt agricultural technologies, and preserve soil fertility. The use of GIS technologies in combination.
