Abstract

Phosphogypsum is not only a valuable meliorant for saline soils, it is also a multicomponent fertilizer that improves the soil structure and physical properties. Long-term research allowed to prove agronomical and economical efficiency of phosphogypsum application, to develop regulations for its application in agriculture. As the greatest result of all research work phosphogipsum was included to the Goverment subsidy program as gypsum-containing meliorants
