One-sided phosphoric fertilizers based on off-balance ore of phosphorites of the central kyzyl kum and their water-insoluble part

This article presents the results of laboratory studies on the production of unilateral phosphorus fertilizers from off-balance ore of phosphorites of Central Kyzylkums. The relative content of digestible form R2O5 by citric acid and trilon B varies within 63.31-76.64% and 62.80-74.89%, respectively. The strength of phosphorus fertilizers is not less than 1.6 MPa. It was determined that the relative content of the digestible form R₂O₅ by citric acid and trilon B in the water-insoluble part of one-sided phosphorus fertilizers is from 39.91 to 57.84%.
