Abstract

The article deals with the question of changing the microbiological state and biological activity of the soil in different potato fertilizer systems in the short-term crop rotation of Polissya. It was found that with the consistent application of ma-nure with moderate mineral fertilizer standards, the structure of microbiological cenosis of the soil changes: against the background of their aftereffects, the total number of microorganisms increases by an average of 31%, ammonifiers - by 33%, phosphor mobilizing bacteria - by 2.6 times. The coefficients of mineralization and soil oligotrophy are calculated. It has been proved that all biological processes have positive correlation bonds with the total number of microorganisms, bacteria that use mineral nitrogen forms, ammonifiers, phosphoramidizers and actinomycetes.
