Processing of Local Agro Ores of Karakalpakstam for High-Efficiency Fertilizer

Abstract

The chemical composition of glauconite sands and zhelvak phosphorites of Karakalpakstan used as raw materials for production of complex mixed fertilizers has been studied. Physical and mechanical characteristics and chemical compositions of raw materials - glauconite sand and gelvac phosphorites of Krantau, Khujakul and Beshtyubinsk deposits are given. Several methods of introducing glauconite sand and gelvac phosphorites into the soil have been studied. Thermal analysis of the studied complex glauconite-containing fertilizers consisting of glauconite, monoammonium phosphate and potassium chloride is also provided.
