Abstract

It is shown that the water content in the upper part of chernozems in Western Siberia in the late fall period exceeds the field capacity. An ice-rich barrier is formed in the humus horizon of these soils at temperatures below zero in the cold period. This barrier has both negative and positive effects. Being impermeable for snowmelt water, it favors the development of erosion processes. At the same time, it prevents infiltration of snowmelt water beyond the soil profile with the formation of a percolative water regime (favoring soil leaching) in the chernozems.
