Amelioration of Coal Mine Spoils through Fly Ash Application as Liming Material

Applications of either flyash from a coal-fired power plant or lime significantly raised the pH of acidic coal mine spoils. Both flyash and lime also increased the availability of phosphorus, potassium, and sulfur, and the uptake of these nutrients and the oven-dried biomass of potted test cultures...

Description
Summary:Applications of either flyash from a coal-fired power plant or lime significantly raised the pH of acidic coal mine spoils. Both flyash and lime also increased the availability of phosphorus, potassium, and sulfur, and the uptake of these nutrients and the oven-dried biomass of potted test cultures of Sudan grass (Sorghum sudanens) and oats (Avena sativa). A significant reduction in bulk density of the mine spoils was observed only with flyash application. Results show that flyash is a potential alternative to lime for amending coal mine spoils in preparation for revegetation.
