Abstract

The humus state of soils significantly affects their acid-base state, taking into account the pKa, its functional groups and their quantity. The development of the sod soil-forming process in sod-podzolic soils, due to the vertical transfer of Ca, Md, K from horizons B and BC to Ap, with an increase in the intensity of biochemical weathering, led to the neutralization of acidity in the Ap horizon. It has been established that the organic matter of soils has a much larger capacity than the mineral part of soils. It is shown that in the process of excessive moistening of sod-podzolic soils of different degrees of cultivation, the Eh value changes in them in different ways: a greater drop in Eh (DEh/Δt) from -3.3 - in cultivated soil to -5.6 mv/day – in cultivated and with a decrease in Eh in cultivated soil to 235 mv, in cultivated sod-podzolic soil – up to 127 mv. Keywords: HUMUS, SOIL ACIDITY, REDOX STATE, SOD-PODZOLIC SOIL
