Influence of the direction of use of deposits on some agrophysical properties of soils

The article presents the results of the assessment of the transformation of the structural composition and density of the composition of the soils of the deposits overgrown with forest, as well as re-developed, in comparison with the areas of pure deposits. The research was carried out in a group of areas of the forest-steppe zone on leached chernozems, dark gray forest and dark brown floodplain soils, as well as in the zone of grass forests on dark gray soils. The direction of use of deposits affects the structural composition, the number of agronomically valuable fractions, the density of addition and the spatial variation of these agrophysical properties. Statistically, a high proportion of the contribution of the direction of use of the deposit to the change in the structural composition of soils and the density of addition has been established.
