ACTIVATION OF KYZYLKUM PHOSPHORITES WITH UREA NITRATE

One of the ways to effectively use phosphorites is by chemically activating them with mineral acid complex compounds of urea (urea nitrate, urea phosphate, urea sulfate) to obtain complex phosphorus fertilizer with gradual effect [1-4]. Phosphorites with nitric acid compound of urea are processed using non-traditional methods, providing an opportunity to organize the production of phosphorus fertilizers in the places of use
