The study identified the patterns of change in podzolic soils forming over different parent rocks at early stages of reforestation upon clear-cutting of pine stands. Soils of the first chronosequence, representing Albic Podzol, demonstrated an illuvial distribution of organic matter down the soil profile, with its maximum deposition in the forest litter. As more time passed since logging, mineral horizons gradually got enriched in organic matter, and a thin organo-mineral horizon with elevated carbon and nitrogen content formed under the forest litter by the age of 8 years. The second chronosequence, representing Entic Podzol, displayed a slight reduction in soil richness upon logging, due to intensive humification and mineralization of organic matter. The study found proof that logging using multifunctional machines helps preserve the living ground cover and the top organic horizons in a substantial part of the logging site. Natural reforestation in sites with soils relatively rich in organic matter proceeded through settlement of deciduous species, whereas sites on poor soils were naturally reforested by pine.
