Organic fertilization is the main agro-technical measure by which the humus regime in the soil is positively influenced. Organic fertilizers are sources of raw material for nutrient humus, but also for the synthesis of stable humus. Both contribute, along with other links of plant culture technology, to maintaining or increasing the humus content of cultivated soils. The article reflects the supply of delluvial chernozem with humus in the application of wine lees, vinasse (waste from winemaking plants) and cereal borhot (waste from the Ethanol Alcohol Production Facility). It has been established that the waste has significantly enriched the soil with humic organic matter. The specific humus increase in the pore layer from 1 ton of waste incorporated as fertilizer was for: wine yeast - 95-99 kg, vinasse - 5-7 kg, cereal borhot - 24-29 kg. The influence of waste on the quality of humus in the soil has been determined and the balance sheet has been calculated.
