The study presents counts of different groups of microorganisms occurring in the upper horizon of black earth (Phaeozems) following long-term maize monoculture growing under various tillage regimes (A -- direct sowing, B -- direct sowing with introduction after 10 years (2008) of a single autumn deep ploughing, C -- direct sowing with introduction after 10 years (2008) of a single autumn deep ploughing together with a full dose of farmyard manure). Samples were collected from two depths (0-15 and 15-30 cm). Numbers of oligotrophs, copiotrophs, actinomycetes and fungi against the background of soil basic physico-chemical properties were determined. The obtained research results were subjected to statistical analysis. It was found that principal physico-chemical properties of the examined soil were, generally speaking, similar. In addition, no significant differences between the numbers of many groups of microorganisms and methods of cultivation were observed irrespective of the depth of soil samples collection.
