Uptake of multielements by corn from fly ash-compost amended soil

Abstract

Abstract. Fly ash was collected from a coal-fired power plant in and near the U.S. Department of Energy Savannah River Site to study the feasibility of the application of fly ash compost mixture to soils for the availability and uptake of various elements by corn (Zea mays L.). The crop was grown in potted Ogeechee sandy loam soil using eight treatments: soil alone, soil amended with 15% compost, and soil amended with 2, 5, 10, 15, 20 and 25% of fly ash-amended compost. It was observed that 20-25% fly ash and compost soil ratio treatments generally increased plant growth and the yield. The plant uptake of K, Mn, and Cu increased with increasing percentages (2-25%) of fly ash+compost: soil ratios. The total content of K in plants was positively correlated with the dry matter yield of corn. This study indicates that the application of fly ash blended with compost to soil is beneficial to corn production without causing any deleterious effects on plant growth and plant composition.

Investigation of sewage sludge stabilization potential by the addition of fly ash and lime

“…Furthermore, the combined addition of fly ash and lime in small dosages to sewage sludge may result to an efficient removal of pathogens, although limited efficiency of the pasteurisation process was observed by the addition of fly ash alone to sewage sludge, even at high dosages exceeding 55% on a dry basis [13,14]. During the examination of fly ash potential as a sludge stabilization agent, it was concluded its beneficial role to plant production, without causing any deleterious effects on plant growth or plant composition [15].…”

Wheat and Soil Response to Wood Fly Ash Application in Contaminated Soils

“…Many papers have been published concerning possible land application of coal fly ash (Adriano et al, 1982, 2002; Menon et al, 1990; Carlson and Adriano, 1991; Ghuman et al, 1994; Adriano, 2001; Sajwan et al, 2003). However, little is known about the use of wood fly ash.…”

Adsorption−Desorption Studies of Selected Herbicides in Soil−Fly Ash Mixtures

“…The application of fly ash in agriculture as a fertilizer in order to improve the physical and chemical properties of soil is reported elsewhere (El-Mogazi et al, 1988). The increase of corn growth and yield was reported for soil amendments with fly ash compost in the 2-25% range (Ghuman et al, 1994). The uptake of K, Mn, and Cu was found to increase with increasing percentages of fly ash compost in the same study.…”
