COMPARATIVE CHARACTERISTICS OF SOIL PHYSICAL PROPERTIES OF DIFFERENT TYPES OF CHERNOZEMS ORENBURG ^{[№ 12 ' 2011]}
Density, permeability, and maintenance of soil agronomically valuable aggregates were studied in the Orenburg region of typical chernozem, ordinary divergent slopes and southern black soils. These physical properties of black nozemah are optimal. The results showed that physical factors such as structural condition, soil density and water permeability, and typical chernozem chernozem ordinary northern slopes are much better data than the southern black soil and ordinary chernozem southern slope.
