Experiments in reclaiming acidic surface-mined coal lands with raw fly ash from bituminous-coal-fired powerplants were conducted by the Bureau of Mines at two sites in northern West Virginia. Plots at both sites were treated with varying tonnages of fly ash from three area powerplants and were planted with a variety of grasses, legumes, trees, and shrubs. Eight grasses and seven legumes were investigated. Greatest promise for growth under harsh soil conditions was shown by Kentucky 31 Fescue, rye and red top grasses, and Birdsfoot Trefoil, a legume. Survival of trees and shrubs was negligible. Addition of fly ash to the spoil increased the ph to a range tolerable to some types of plant growth, improved the texture of the soil, and increased the available water of the resulting mixture.
