“…Problems related to classification, nomenclature and diagnosis of soils transformed due to hydrometamorphism, erosion, justification of terms and formulation of concepts (waterlogging, degradation, physical degradation, slitogenesis (development of vertic properties in soils), permissible erosion rate, etc.) have been covered in works of a large number of authors [ 6,7,8,9]. Views on the soil-forming processes in soils hydrometamorphised soils (without the naming of the latter as such) is presented in works by N.B.…”

The work presents the observational data of soil cover structure dynamics, changes in soil composition and properties under the influence of anthropogenic impact. A decrease of 6.0-7.4% in the share of black soils (Chernozem) over 50 years of observations and a corresponding increase in the area of waterlogged soils associated with closed depressions have been revealed. Due to the high dynamism of soil density with changes in its moisture content, a criterion has been sought to characterize this dependence and a method has been proposed to describe it using dynamic curves. The amplitude of density fluctuations and its dependence on the severity of anthropogenic degradation – 59 -78% – has been established. Correlation analysis confirmed a medium strength relationship (determination coefficient 0.39-0.42) between shrinkage and specific surface area of initial degradation soils and a strong relationship (determination coefficient 0.79-0.86) in meadow-chernozem compacted soils. A strong correlation has been found between the volumetric shrinkage and fines content in the size distribution (determination coefficient 0.84-0.96). A new diagnostic criterion (“T” criterion) for the intensity of hydrometamorphism and, in general, for the physical aspect of anthropogenic soil degradation has been proposed.
