Effect of soil compaction on microbiological activity in the calcareous chernozem soil under sugar beet has been studied. It was found that the number and activity of microorganisms depends on the degree of soil compaction, kind of microorganisms and type enzymes. Soil compaction reduced the total number of aerobic bacteria and the number of ammonifiers, nitrifiers, actinomycetes, fungi, azotobacter, oligonitrophilous bacteria and cellulolytic microorganisms and increased the total number of anaerobic bacteria and denitrifiers. Also, soil compaction reduced the dehydrogenase, protease and urease activities of microorganisms.
