This is confirmed by indicators such as the degree of weathering of the soil mass, according to which the studied soil sialitnym close to having a slight degree of weathering. The maximum value of Shvertmana (maximum degree hydromorphism ) was observed in sod-podzolic soil and leached chernozem. According to the degree of ferruginous soils studied have average and moderately low values​​, and the degree oksidogenez – moderately low, low to very low.
