The results of calculations of the properties of various soils of the South of West Siberia over their probabilistic statistical distributions are presented. It is demonstrated that the statistical entropy of the properties can serve as one of the systemic criteria of the evolution and dynamics of top soil under natural and anthropogenic processes. It is established that the entropy of humus content of soil within one zone depends on the grain size distribution. It is proved that deflation, ploughing and irrigation decrease the entropy of humus content, while soil-protecting agriculture increases it.
