Parameters for changing physical, chemical and agrochemical indicators in the soil for the establishment of various biological indicators. Scientific sound (intermediate). A theoretical analysis of modern organic fertilizer systems was carried out, as well as an assessment of their congestion in the minds of the Forest Steppe of Ukraine. It has been established that for an organic fertilizer system of 12 t/ha and 6 t/ha of VRS pus per 1 hectare, stabilization of physical and chemical indicators in the gray fox soil, the sum of the removed bases on the level of 6.0 and 5.40 mg/eq. soil, for the introduction of organo-mineral bioactive fertilizers (OMBD) at a dose of 2 t/ha - 7.0 for the control 4.8 mg/eq per 100 g. 5.0 and matched the control. It was determined that the application of OMBD (2 t/ha) in crops of winter wheat, peas and oats contributes to the activation of the functioning of soil microbiota, which is accompanied by an increase in their number by 1.1-3.2 times, intensification of the transformation of organic matter in the soil and cellulolytic activity in 1.3-1.6 times compared to the control, as well as preservation of nutrient reserves in the soil solution (Ko = 0.4-0.79). It was determined that with organic fertilization systems and the use of the latest bio-organic fertilizers, it is possible to achieve reproduction of the potential fertility of the gray forest soil. It was established that the use of OMBD at a dose of 2 t/ha according to crop yield indicators is at the level of application of 12 t/ha of cattle manure per 1 ha of crop rotation area and reaches 4.85 t/ha for winter wheat grain, 2.53 t/ha for peas and oats 4.04 t/ha with a yield increase of 52 and 44% compared to the control. The level of profitability was 210, 135 and 182%, respectively.
