Influence Of Coal Combustion Flue Gas Desulfurization Waste On Element Uptake By Maize (Zea Mays L.)

PDF Version Also Available for Download.

Description

A greenhouse study was conducted to determine the effect of coal combustion flue gas desulfurization (FGD) waste from a coal combustion electric power facility on element uptake by maize (Zea mays L.). Unweathered FGD was applied to an Orangeburg Series (Typic Paleudult) soil with an initial soil pH salt of 4.90. The FGD was added at 0, 1, 2, 4, 6, 8, and 10 per cent by weight. The test plant, maize, was harvested after 6 weeks of growth. Within 56 days of the FGD application, all rates of FGD significantly increased pH in the soil and the soil leachate ... continued below

Description

Unweathered FGD was applied to an Orangeburg Series (Typic Paleudult) soil with an initial soil pH salt of 4.90. The FGD was added at 0, 1, 2, 4, 6, 8, and 10 per cent by weight. The test plant, maize, was harvested after 6 weeks of growth. Within 56 days of the FGD application, all rates of FGD significantly increased pH in the soil and the soil leachate above 6.0. The elemental concentration of the maize tissues indicated a characteristic elevation of B, Se, Mo, and As. However, no visual symptoms of toxicity of B or other elements in plants were observed. Increasing level of FGD caused a steady decline in dry weight, with the highest treatment producing plants which had approximately half the biomass of the control plants. Due to elevated concentrations of B and other elements and due to adverse yield effects measured on plants, unweathered FGD would not be a suitable amendment for 6-week old maize on this soil.
