TECHNOLOGY OF PHOSPHORITE AND GLAUCONITE-BASED PHOSPHORITE FERTILIZERS IN KARAKALPAKSTAN

In order to develop a simplified technology for obtaining phosphorus fertilizers, the process of chemical activation of Khojakul phosphorite flour with mineral fertilizers, which are the main standard fertilizers in agricultural production, was studied. Decomposition of glauconite with nitric, sulfuric and phosphoric acids was carried out. The process of decomposition of glauconite with acid is normal, but after 1.5-3 hours it decreases sharply. The acid has a debilitating effect on glauconite. KEYWORDS: Phosphorite, glauconite, activate, nitric, sulfuric and phosphoric acids, pH, complex compound fertilizer.
