This article deals with production of organomineral fertilizers based on local raw materials cattle dung local ores (Kyzilkum phosphorite flour and Navbahor bentonite) and nitrogen-fixing microorganisms. Based on the experiments the following results were obtained. During 60 days the raw materials selected for the experiment were used in optimal proportions: cattle dung: bentonite: nitrogen-fixing microorganisms solution (100:5:0-4) and the main chemistry of organomineral fertilizers obtained on the basis of cattle dung. bentonite. phosphorite flour and nitrogen-fixing microorganisms. Composition (CD:B:PF:NFM=100:5:5:(0-4)) was analyzed. The physico-chemical and commercial properties of the obtained new type of organomineral fertilizers were studied. The contents of organomineral fertilizer samples were analyzed by modern physicochemical methods. Composting cattle dung with local ores and processing the resulting mixture with a solution containing nitrogen-fixing microorganisms allows to further increase humic substances. assimilable forms of phosphorus and. most importantly. increase. Due to the biofixation of atmospheric molecular nitrogen. the amount of nitrogen increased by 3.4- 4.6 times.
