Peculiarities of humus formation and manifestation of biological activity of soils are revealed. The objects of research are grey forest nonpodzolized, alluvial meadow soils as arable land, meadow-marsh soils as hayfield. Humus condition of the studied soils is in satisfactory condition within each soil type. The current state of the humus fund of old-arable grey forest soils is characterized by low humus content and unsatisfactory composition, which is caused by the absence of fertility change. The productivity of meadow-marsh soils is high and considerably exceeds grey forest and alluvial meadow soils. The information obtained on biological activity, can be used in agricultural practice to assess soil productivity, as well as in environmental monitoring.
