摘要：
For studying depth distribution of major elements in soil profiles, we used preparation of samples which makes it possible to remove carbonates and organic matter without changing actual structure of silicate mineral phases. Such preparation of soil samples also reduces influence of exchange cations on the results of major element chemical analysis. The depth distribution of element oxides and their molecular ratios in profiles of two forest-steppe soils formed in typical for the Middle Volga Region loose deposits were studied. Pretreatment of soils with 1 M CH3COOH and 30% H2O2 provides more realistic information about processes that took place during the formation and evolution of soils and their mechanisms.
