Variability of the chernozem biological properties in the «Stone steppe» preserve on different elements of paleocryogenic microrelief in the conditions of various land use

It is shown that spatial variability of the soil biological properties of the «Stone steppe» preserve, determinative the biological activity, soil organic matter and microbial biomass is caused by influence of a relict cryogenic microrelief. In the conditions of various land use (an arable land, a moving steppe, a forest belt) the distinctions of the soil biological properties generated on different elements of a paleocryogenic microrelief (the block, the interblock), increase at an decrease of the anthropogenic load.
