Evaluate the environmental risks and benefits from agricultural applications of agricultural and industrial byproducts (e.g., FGD-gypsum, compost/manure) including uses to remediate disturbed soils and to sequester and phytoremediate metal from metal contaminated soils
Develop and/or modify existing analytical methods to evaluate physical and chemical properties of byproducts and the potential environmental risks and benefits from their use in agriculture. <P> Characterize mercury (Hg) emissions from FGD-gypsum amended soils. <P>
Evaluate plant species recommended for phytoextraction of Cd from U.S. contaminated soils requiring remediation to protect food safety.
