Аннотация: A comparison of the biological activity and biogenicity of drained and nondrained gleyed agrogray soils (Luvic Greyzemic Stagnic Phaeozems) of Moscow oblast has been carried out using such indicators as microbial biomass carbon (Cmic), basal respiration (BR), and the contents of organic carbon (Corg), particulate organic matter (СPOM), and potentially mineralizable organic matter (C0). It has been found that the СPOM fraction turned out to be one of the indicators of the initial waterlogging stages, while the Cmic and BR indicators are sensitive to the degree of soil hydromorphism. It is proposed to evaluate soil biogenicity using Сorg and СPOM parameters; while С0, Сmic, and BR parameters should be applied to evaluate soil bioactivity. Gleyed agrogray soils at different stages of waterlogging are close in their biogenicity but differ in bioactivity. The humus state of the gleyed agrogray soil changes during the period of efficient functioning of drainage. The gleyed agrogray soil in terms of biogenicity and bioactivity becomes similar to its automorphic zonal analog.
