Objective. This article deals with production of organomineral fertilizers based on local raw materials cattle dung (cattle). local ores (Kyzilkum phosphorite flour (PF) 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 (NFM) (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. Methods. The obtained results from our side were first studied the quantities of organomineral fertilizers based on cattle dung. bentonite and nitrogen-fixing microorganisms. Cattle dung. bentonite and nitrogen-fixing microorganisms of the type Azotobacterium were used for laboratory research. For this. cattle dung: bentonite ratios were taken in the range of 100:(2.5-5) and the resulting mixture was processed with nitrogen-fixing microorganisms (NFM) grown in Fedorov medium in the ratio of 100:(2.5-5):(0.5-4.0).
