Аннотация:In the humus-enriched horizons of podzolic and peaty-podzolic gleyic soils, 76-90% of the standard CEC is ensured by mineral components in spite of the high humus content. This can be attributed to the presence of Al, which is not displaced into solution during CEC determination, on functional groups of organic acids, as well as to the presence of weakly humified organic matter with low CEC.
