The article provides information on the effects of inoculation with nitragin and application of mineral
fertilizers on the microbiological properties of the soil before sowing the seeds of legumes (soybeans,
beans, mungbeans), grown as a secondary crop after winter wheat. At the end of the vegetation
period of repeated crops, it was observed that the amount of microorganisms in the soil increased
compared to the initial indicators, the amount of ammonifiers and oligonitrophils increased, and the
amount of micromycetes and actinomycetes decreased. Before sowing the seeds of legumes
(soybeans, mungbeans, beans) grown as a secondary crop, the amount of ammonifiers, oligonitrophils
and micromycetes increased, and the amount of actinomycetes increased compared to the control
option in the backgrounds treated with nitrogen-fixing bacteria.
