The study of vital activity regulation of soil microorganisms is one of the general problems of soil microbiology. One of the factors influencing the existence and reproduction of bacteria in terrestrial ecosystems are fertilizers introduced into the soil. The effect of mineral fertilizers on the reproduction of bacterial complexes in soils of diverse types at different temperatures (4 ° C and 20 ° C) was studied. Mineral fertilizing promotes the active reproduction of saprophytic bacteria in calcaric cambisol (CCS) and distric cambisol soils (DCS). The variants with fertilizers can be arranged according to their effect on the reproduction of saprophytic bacteria in following order, regardless of the soil type: soil with nitric fertilizer > soil with phosphoric fertilizers > soil with potash fertilizer. Introduction of nitric or phosphoric fertilizers at 20 °C was more successful in CCS. It was found that application of mineral fertilizers positively affects the conservation and reproduction of bacteria in soils of diverse types. Prolonged application of mineral fertilizers reveals a positive effect on bacterial complexes, regardless of the soil type.
