Abstract
The article presents the results of studies of changes in the main indicators of fertility of sod-podzolic soils of slope lands under the influence of erosion processes. Determined the ranges of their reduction depending on the degree of erosion, constituting up to 20–30 % on weakly eroded soils, up to 30–40 % on moderately eroded soils, and up to 40 % and more percent on heavily eroded soils.
 The presence of trends in multidirectional changes in the content of humus, mobile phosphorus, mobile potassium and mineral nitrogen in the conditions of industrial crops on soils of various genesis and the degree of manifestation of erosion processes has been established.
