• Description:
  Strip mine scars, coal refuse piles, and fly ash dumps are solid wastes resulting from the mining and combustion of coal. The total unreclaimed area resulting from these wastes is over 2 million acres. Disposition of these wastes is obviously a monumental problem. Large-scale field experiments in the reclamation of acid surface-mined coal lands and refuse piles with raw fly ash from bituminous-coal-fired powerplants were conducted at several sites in northern West Virginia. Plots were treated with varying tonnages of fly ash from area powerplants and were planted with a variety of grasses, legumes, trees, and shrubs. Greatest potential for growth and survival under harsh soil conditions was shown by Kentucky 31 Fescue, rye and red top grasses, and by Birdsfoot Trefoil, a legume. Application of fly ash to the acid materials increased the ph to a range tolerable to plant growth, improved the texture of the soil, increased the water-holding capacity of the resulting mixture, and added trace nutrients to the soil.
