The paper discusses aspects of the influence of organo-mineral fertilizer, which is poultry waste fermented with the help of a complex of microorganisms, on the structure of the soil. The technology for the preparation of organo-mineral fertilizer is complex and involves cascade fermentation of spent litter masses, their integration with mineral components under conditions of correction of the environmental reaction. This ensures the minimization of losses of biogenic elements (nitrogen, phosphorus, sulfur, and others) in the process of destruction. This approach, on the one hand, reduces the volume of emissions of gas fractions into the atmosphere, and, on the other hand, determines the transition of biogenic elements into mobile forms available for plants in the fertilizer composition. A reliable positive effect of the developed fertilizer on the chemical composition of the soil and its characteristics such as air and water permeability. The use of organo-mineral fertilizer on leached chernozem contributes to the preservation and increase of humus reserves, enrichment of the soil with its mobile components. A change in the characteristics of the physical state of the arable soil layer is shown, which manifested itself in soil decompaction, an increase in the proportion of structural components of an agro-valuable size and the number of water-stable aggregates. The application of fertilizer provides the best agro-physical properties of the soil by reducing the bulk density to 0.25 g/cm3, increasing ACF by 4.5% and VA by 10.6% compared to the unfertilized background.
