Several mulching agents were evaluated for their economic feasibility and revegetative responses on surface mines in eastern Kentucky. The most widely used soil amendments are wood fiber mulches. Wood fiber mulch, along with a seed and fertilizer mixture, is suspended in water for a one-step revegetative effort. Alternative mulches, such as processed municipal waste, bark, general sawmill residues, and straw and hay with asphalt binders, were evaluated for their economic feasibility. Each mulching system's equipment, labor, and daily area of application were evaluated. Costs per acre indicated that processed bark was the least expensive to apply on outslopes and hollow fills. The machinery for applying mill residue was more complex and required that the mulch be processed before its application with a truck-mounted thrower unit. In the two most heavily mined regions of eastern Kentucky, bark resources were available in sufficient quantity to revegetate 2956 acres annually at the recommended rate of 45 cu yd/acre. Almost all these mill residues required processing to improve quality, reduce equipment breakage, and increase east of handling. (Author)
