The article is based on the preparation of a three-component composite mixture based on phosphogypsum, an interpolymer complex and humus and its study. It is known that phosphogypsum is a waste product of the chemical industry.. The results of scientific research and practical experience have convincingly proved the technical feasibility and expediency of using phosphogypsum in the national economy instead of traditional types of natural raw materials. A brief description of phosphogypsum, promising areas of its processing and some statistical data are presented. The article deals with the use of a chemical meliorant based on phosphogypsum for effective fertilization in various soil and climatic zones for cereals, vegetables, industrial and other agricultural crops, to improve the soil structure. That the use of phosphogypsum as a chemical meliorant improves the chemical, physical and water-physical properties of saline soils.
