Reducing phosphorus export from croplands

Reducing phosphorus export from croplands with FBC fly ash and FGD gypsum. The FGD reduced water-soluble phosphorus with the little effect on plant-available phosphorus . From an environmental perspective, FBC fly ashes may contain boron, selenium and other trace element concentrations that may be toxic to plants and animals if applied to cropland or pastures in large amounts. Therefore

Introduction to FGD Gypsum

Introduction to FGD Gypsum. FGD Gypsum is a unique synthetic product derived from flue gas desulfurization (FGD) systems at electric power plants. Sulfur dioxide emission control systems used by coal-fired power plants remove sulfur from combustion gases using "scrubbers." One particular type of scrubber that uses lime or limestone reagent (i.e., a substance used in a chemical reaction to
