Elemental uptake by sorghum sudan grass from a flue gas desulphurization waste amended soil. American Society of Agronomy Annual Meeting. (On CD) Interpretive Summary: Technical Abstract: A greenhouse study was conducted to assess the effect of flue gas desulphurization (FGDW) waste on elemental uptake by sorghum sudan grass (Sorghum sundensis L.). Unweathered FGDW was applied to an Ogeechee loamy soil (Typic Paleudult) at 1, 2, 3, 4, 5, and 6% by weight. The sorghum-sudan grass was grown for six weeks in FGDW amended soils. Harvested plant materials as well as soils were analyzed for various elements. The study indicated that increasing levels of FGDW caused a steady decline in biomass production. In addition, a characteristic elevation of B, Se, Mo, and As in plant tissues was also observed. In this presentation, growth performance, biomass production, elemental uptake and accumulation (leaching potential of FGD amendment) will be discussed. |
