Technical Abstract: Flue gas desulfurization gypsum (FGDG) is a by-product of conversion of sulfur dioxide into solid waste from coal combustion power generation plant. This by-product is rich in calcium, magnesium, and contains various other essential plant nutrients. The beneficial use of application of this waste as soil amendments to corn is evaluated. Biomass production (six-week old seedlings) was greater with FGDG application 1% by weight of soil as compared to greater rates of application (2-10%) or no application. With increasing rate of FGDG, the concentrations of boron, selenium, and arsenic in the biomass increased. Further investigation is needed to evaluate these elements and examine the impact of grain yield and quality.
