Abstract

The article presents the results of studying the effect of a solution containing nitrogen-fixing microorganisms (Azotobacter chroococcum) on changes in the chemical composition of composts prepared on the basis of mature compost of cattle manure and bentonite of the Navbakhor deposit, depending on the mass ratios of the initial components and the duration of composting. It is shown that pre-treatment of a mixture prepared on the basis of manure and bentonite using a solution containing nitrogen-fixing microorganisms before composting increases the content of nitrogen, humic substances. It has been established that within two months under optimal conditions, the content of bound nitrogen increases from 0.386 to 1.70%, in addition, the degree of humification of organic substances increases from 50.56 to 65.08%. The optimal conditions are determined. The use of this bioorganic fertilizer makes it possible to provide plants with the necessary nutrients during the growing season without the use of nitrogen-containing mineral fertilizers.
