ON THE QUESTION OF THE STABILITY OF SOD-PALE-PODZOLIC SOILS FORMED ON POWERFUL LIGHT LOESS-LIKE LOAMS TO AGROGENIC INFLUENCES

Abstract

The article presents а new interpretation of humus-granulometric relations of sod-pale-podzolic light loamy soils as a result of the cultural process of soil formation. The presence of a general principle of the relationship between the fractions of particle size distribution and the humus state, in particular, between the humus content in physical clay, the humus content in the soil and the grain size fractions through dynamic equilibrium constants is shown. An attempt was made to evaluate the degree of soil stability on the basis of indicators of humus-granulometric relations, buffering in the acid and alkaline ranges, and cation exchange capacity. The data obtained can be used as a new method for assessing soil fertility and stability as a result of agrogenic effects.
