Abstract

The features of the granulometric composition and density of the southern chernozem for different types of facies of the Elshano-Guselskaya plain are revealed. Thus, the facies types revealed a decrease in the fractions of physical clay in the facies of hollows (II) and gentle slopes (III) (IIn - 46.14 %, IIIn - 47.03%, IIIs - 45.47%) and a natural increase in the fraction of physical sand on them. On facies of low-level slopes (In, Is), inter-basin watersheds (IVn, IVs), and watershed (V), physical clay dominates or equals physical sand in the soil structure, and is, respectively, 70,98%, 50,42%, 55,10 %, 49,42%, 49,97%.
