Introduction
The profile change of the chemical composition of the soil is occur in the process of soil formation as a result of the destruction and formation of new minerals. This phenomenon is accompanied by a variety of basic soil formation processes (BSFP). As an example of the transformation of the parent substrate lead form system the soil profile horizons: O – A – E − B1t – B2t – C [1], which is formed by eluvial-illuvial distribution of substances. Classifying types of distribution of substances in the soil profile [2], selects the type of eluvial-illuvial distribution, which is especially the case for podzol series soils.
