Influence of mineral fertilizers and inoculation with microbial preparation Diazobacterin on formation and functioning of microbial associations in rhizosphere of winter rye was studied on sod-podzol soils. It was shown that application of nitrogen fertilizers increase number of microorganisms that utilize mineral and organic nitrogen compounds. The mostpositiveimpactonthedevelopmentof diazotrophswasobserved in variants with doses that do not exceed 60 kg/ha. Application of high fertilizer doses results in intense growth of denitrifying microorganisms. InoculationwithDiazobacterinpromotesgrowthofagricultureimportant microorganisms.
