Abstract: Coal combustion produces carbon dioxides, SOx, NOx and a variety of byproducts such as coal ash, flue gas, precipitate and so on. Flue gas desulphurization gypsum used calcium-based material as absorbent, fixed SO2 in the form of calcium sulphate, eventually produced a kind of flue gas desulfurization byproducts. Flue gas desulphurization gypsum could affect the physicochemical characteristics of soil and plant because it had rich essential elements, especially B and S, so flue gas desulphurization gypsum had wide application in agriculture. The author summarized the characteristics of flue gas desulphurization gypsum and its effects on environment, especially the application in saline soil improvement. Flue gas desulphurization gypsum, which is an effective and safe soil conditioner in agricultural production, has been verified by a lot of field experiments, but the biological process and interaction of lack and excessive application of flue gas desulphurization gypsum need further research.
