This study analyzes the process of activating phosphorite dust using complex compounds of urea with mineral acids (HNO₃·CO(NH₂)₂, H₂SO₄·CO(NH₂)₂, and H₃PO₄(EPA)·CO(NH₂)₂ based on extraction phosphoric acid). Complex fertilizer samples were prepared in various proportions from 9:1 to 1:9 with a total ratio of 10. According to pH analysis, a decrease was observed from 6.84 to 1.51 in urea nitrate, from 6.91 to 1.76 in urea sulfate, and from 6.43 to 2.16 in urea phosphate based on extraction phosphoric acid. This promotes the decomposition of minerals in phosphorite and the conversion of phosphorus into an assimilable form. The obtained results provide an important scientific basis for the development of a new type of efficient complex fertilizers.
