Abstract: Inoculation is the best way to ensure good nodulation with the proper strain of nitrogen-fixing bacteria for increasedyield in an environmentally safe manner. This investigation was conducted on three -year experiment which was setup in four replications with three-crop rotation (maize-soybean-wheat) at experimental field of the Institute of Fieldand Vegetable Crops, Novi Sad, Serbia. Effects of application of microbiological fertilizer (with nitrogen-fixingbacteria Bradyrhizobium japonicum) on root mass, number and mass of nodes per plant, soil biogeneity (number ofammonifiers, Azotobacter, actinomycetes), as well as the effect on soybean yield were studied. Obtained resultsindicated positive impact of inoculation on nitrogen fixation parameters. The higher amounts of mineral nitrogenhad negative impact on atmospheric nitrogen fixation, that is, by increasing preplanting mineral nitrogen amount inthe soil by 1 kg, the amount of calculated nitrogen from the air was decreased by 1.72 kg. Increasing abundance ofstudied microorganisms in the rhizosphere, as well as soybean yield using microbiological fertilizer was stimulatedby plowing under crop residues. The impact of meteorogical conditions on the effects of inoclutaion was verysignificant.Key words: I
