摘要

The ecological features of the humus formation in typical, ordinary, and southern chernozems ofthe Orenburg Cisural region were considered. The fractional–group composition and amphiphilic properties ofthe forest-steppe and steppe chernozem subtypes were studied in relation to the dynamics of the hydrothermalregime, the vegetation, and the biological (enzymatic) activity of these zonal soils. The particular properties of the humus in virgin and arable landscapes were established. Arguments were presented for the probable existence of a genetically controlledrelationship between the fractional–group composition of the humus and itsamphiphilic properties.
