The aims of this investigation were to examine the effect of application of root nodule bacteria (single strain, mixture of strains, microbiological fertilizers Nitragin) on the total number of microorganisms, the numbers of fungi, actinomycetes, azotobacters, free nitrogen-fixing bacteria and ammonifiers and the activity of dehydrogenase, as well as how the application of bacteria affects some parameters of nitrogen fixation (dry matter mass, percentage and content of nitrogen). In the variant with Nitragin, the total number of microorganisms and the numbers of fungi, azotobacters and free N-fixing bacteria increased. The largest number of actinomycetes was found in the variant with the mixture of strains. The largest number of ammonifiers was found in the variant with the single strain. The dydrogenase activity, dry matter mass, percentage and content of nitrogen were increased in the variants with the single strain and the mixture of strains.
