It was found that inoculation with nitrogen and application of mineral fertilizers before sowing the seeds of bean crops grown as a secondary crop after winter wheat affected the agrochemical and microbiological properties of the soil. Inoculation of bean seeds with nitrogen before sowing and application of mineral fertilizers in different doses provided an increase in the amount of humus in the topsoil (0-30 cm) layer by 0.021-0.034% compared to the initial values, and the total nitrogen content by 0.006-0.009%. It was found that the increase in the number of mineral fertilizers in the background inoculated with nitrogen before sowing the seeds of beans grown as a secondary crop led to an increase in the number of ammonifiers, oligonitrophils, micromycetes, and actinomycetes compared to the control option.
