Abstract

The article presents the results of the development of a technology and a production line for the production of bionutrients for use in crop production in order to increase plant resistance to adverse climatic factors and reduce doses of pesticides and mineral fertilizers. The technology is based on the bioconversion of organic animal waste into coprolites (biohumus), uses the nutritional activity of earthworms. and this is a kind of solid-phase fermentation, where the fermented mass is a heterophase system of the type: solid phase - liquid - gas. Compost as the basis for the vital activity of earthworms is prepared by accelerated biotechnological processing of animal manure and other organic materials. Nutrients are converted by worms into coprolites - forms available to plants.. The humus of coprolites differs in chemical composition from humus formed in the soil with the participation of microflora, in that polymerization processes of low molecular weight decomposition products of organic substances develop in the digestive canal of worms and humic acid molecules are formed. The resulting product was tested for effectiveness on winter rye crops. A noticeable increase in resistance to climatic factors and an increase in yield while maintaining high nutritional qualities is shown.
