PHOSPHORITES OF KARAKALPAKSTAN AND THEIR USE IN AGRICULTURE AS LOCAL FERTILIZERS
Keywords:
low-grade phosphorite, agriculture, nitrate, urea, potassium chloride, new form,perspective.Abstract
In order to create scientific foundations and develop a technology for producing phosphorus-containing fertilizers, the process of activation of low-grade phosphorites with mineral salts - ammonium sulfate, ammonium nitrate, mono ammonium phosphate (ammophos), urea nitrate, ammonium chloride, potassium chloride and urea was studied. Chemical methods of activation of phosphorites of Karakalpakstan can significantly expand the prospect of supplying agriculture with new forms of phosphorus fertilizers.
