PRINCIPAL TECHNOLOGICAL SCHEME FOR OBTAINING NITROGEN-PHOSPHORUS-CALCIUM FERTILIZER WITH IMPROVED PROPERTIES

Abstract

The study examined the process of obtaining nitrogen-phosphorus-calcium fertilizers based on the incomplete decomposition of washed and treated Central Qizilqum phosphate concentrate. To improve the properties of fertilizers, a method for introducing natural bentonite into the composition of steamed pulp has been proposed. A fundamental technological scheme for the process of obtaining NPSa fertilizers with satisfactory commercial properties has been developed.
