Siberia is characterized by specific climatic conditions with cold winter and hot summer. For a long time Western Siberia was considered to have low soil diversity with peat soils being the most abundant component of soil mantle.Differentiated vs. poorly differentiated soils form due to local hydrothermal, topographical and lithological conditions. Cold environments with seasonal and perennial frost action are the major factor, which influence pedogenesis and appearance of the soils. We hypothesized that initially similar substrated transformed into different soils due to divergent evolution.
