PHOSPHORUS FERTILIZERS BASED ON ACID ACTIVATION OF LOW-ACTIVITY PHOSPHATE RAW MATERIALS

This paper examines the technology for producing phosphorus fertilizers using acid activation of low-activity phosphate raw materials. The influence of acid type, its concentration, and processing regime on the availability of phosphorus in the final product was studied. It is shown that optimal processing parameters significantly increase the content of soluble phosphorus (P₂O₅), which can improve the efficiency of the fertilizers. The results allow recommending the proposed technology for industrial application.
