Description: Organic amendments can be included in minesoil revegetation treatments to produce high-density ground covers or increase the yield of pasture and forage crops. They may provide an alternative to the "topsoiling" requirements under current surface-mining laws and regulations. In this study, shredded hardwood bark, composted municipal waste, and a tannery waste were applied to an acidic minesoil. Supplemental inorganic amendments including fertilizer, agricultural lime, and an alkaline waste from an SO2 scrubber system were applied alone and in combination with the organic amendments. Treatment comparisons were based on vegetation response and chemical and physical characteristics of the minesoil after treatment. Organic amendments are not required for establishing vegetation though some reduced the time required to produce an acceptable cover. Site characteristics, land use objectives, and the availability of organic materials determine the appropriate amendment for a specific site.
