Effects of drainage, subsoiling, conventional and reduced tillage of hydromorphic black soils on the distribution of total microorganisms, ammonifiers, actinomycetes, free nitrogen-fixing bacteria, cellulolytic microorganisms and fungi have been investigated. The application of drainage had a stimulative effect upon the investigated microorganism groups, although great variability was observed in some years investigated. Significant effect was observed with the depth of drainage. Subsoiling, too, resulted in the increase of investigated microorganism groups. Combination of drainage and subsoiling did not show any proportional effect upon the increase of microorganism number. Presence of all microorganism groups was with reduced tillage.
