Large amounts of flue gas desulfurization products (FGDs) are produced when SO 2 emissions are trapped in the coal burning process for generation of electricity. FGDs are normally discarded instead of being reused, and reuse on soils could be important in overall management of these products. Glasshouse experiments were conducted to determine effects of various levels of three FGDs (a FGD gypsum, an oxidized FGD þ Mg, and a stabilized FGD) and the control compounds CaCO 3 , CaSO 3 , and CaSO 4
