Abstract
Currently, due to the rapidly growing population of the planet, with the reduction of arable and irrigated land, providing the population with food and drinking water is becoming increasingly urgent. Despite the enormous achievements in agriculture and livestock farming, this problem remains unresolved at the beginning of the 21st century. One of the most effective ways to solve this problem is to further increase the yield of agricultural crops and the productivity of livestock, poultry, and fish farming. In the world, in almost all developed countries, there is a tendency to increase the production and range of chlorine-free potassium and NPK fertilizers, and feed calcium phosphates. To provide agriculture with chlorine-free potassium and, on their basis, chlorine-free, completely water-soluble NPK fertilizers for drip irrigation and foliar feeding of plants, livestock in feed-grade calcium phosphates, it is necessary to justify a number of decisions: the development of effective methods for producing chlorine-free potassium fertilizers and feed-grade monocalcium phosphate; study of the content of fluorine and other impurities during the concentration of defluorinated and desulfated extraction phosphoric acid (EPA) from phosphorites of the Central Kyzylkum (CK); establishing optimal technological parameters for the conversion process of monosodium phosphate and potassium chloride.
