Anthropogenic activities lead to significant transformations of natural landscapes. In this article, an attempt was made to describe the soil succession in the context of 100-year dynamics of Scots Pine forest stand in Kursk region. The morphological, physical, chemical and physical and chemical characteristics of sandy podzols in the chronological order of pine forests functioning 0 - 70 - 100 years were under analysis. It was revealed that monodominant forest stand of Scots Pine leads to the transformation of soils at the type level. It is noted that forest stand of Scots Pine on Umbric Podzols contribute to the development of the podzolic process at an average rate of formation of the podzolic horizon - 0.11 - 0.17 sm / year. During the time period of the soil succession (100 years), the thickness of the soil profile has increased and the humus reserves in the profile have increased by 47.1%, as well as a total decrease in the content of mineral nutrients is noted. The content of mobile forms of heavy metals (Cu, Zn, Ni, Mn and Co) in the genetic horizons of Carbic Podzols (Arenic) in the time interval of the succession 70 - 100 years decreases by 21.4 - 71.4%.
