Research on saline-alkali soil amelioration with FGD gypsum

Technology basics2.1. Facts of FGD gypsum. Gypsum has been known to be an amelioration agent for saline-alkali soils for more than 100 years; however, it has been used only rarely because of the high cost for the exploitation, transportation, and crushing of natural gypsum. FGD gypsum, therefore, was proposed to substitute natural gypsum.
