The purpose of the work is to study the influence of the main tillage and mineral fertilization on the orientation of mineralization and synthesis processes in typical chernozem. Research methods are microbiological, laboratory and field.Research results. It was established that the minimum value of the total number of microorganisms is observed in the variant with the use of No-till without fertilizers, the average - plowing, the maximum - disking. The introduction of mineral fertilizers leads to an increase in the total number of microorganisms in the No-till variant by 6.36% (N30Р30К45) and 13.5% (N150Р100К120). In the option of disking, the application of fertilizers leads to an increase in the number of microorganisms at the minimum dose of fertilizers (by 13.7%), and to a decrease in the number at the maximum dose of fertilizers by 8.07%. When using plowing, the number of microorganisms decreases even with a minimum dose of fertilizers. The highest level of humus mineralization is observed in the version without fertilizers when No-till is used (23.3%), the average level is when plowing (17.8%), the minimum is when discing (10.1%). The tendency to activate the decomposition of humus compounds at the maximum of the investigated doses of fertilizers is observed both during disking and plowing. The pedotrophicity index in the version without fertilizers has a maximum value when using disking, an average value when using plowing, and a minimum value when using No-till. As a result of application of fertilizers in the dose of N30Р30К45, plowing begins to be characterized by the maximum level of consumption of soil organic matter, when applying fertilizers in the dose of N150Р100К120 – disking.
