Research of the Process of Obtaining Organo-Mineral Fertilizer Based on Nitrogen Acid Decomposition of Non-Conditional Phosphorites of Central Kyzylkumes and Poultry Cultivation Waste

The article presents the results of decomposition of substandard phosphorites at a non-full rate of nitric acid (10-50% of stoichiometry on CaO), followed by its processing by bird droppings in various ratios. The optimal parameters for obtaining organic mineral fertilizers are determined, the techn...

Description
Summary:The article presents the results of decomposition of substandard phosphorites at a non-full rate of nitric acid (10-50% of stoichiometry on CaO), followed by its processing by bird droppings in various ratios. The optimal parameters for obtaining organic mineral fertilizers are determined, the technological scheme is given and the material balance is calculated, the possibility of obtaining nitrogen-phosphorus-humus fertilizers based on substandard phosphorites and bird droppings is shown, by composition (wt.%): P2O5 total - 6.53; Р2О5 acceptable - 4.04; СаО total - 17.12; N - 4.21; organic matter - 28.38; humic acids - 9,12, fulvic acids - 5,25, water-soluble organic substances - 4,2; pН – 5,93.
