A series of test plots were implemented on coal refuse at the J.B. King Mine in south central Utah to determine the effects of soil depth on changes in coal refuse, surface, and subsoil pH and electrical conductivity; correlate the revegetation effectiveness with different soil depths; and compare fertilizer application rates with revegetation success. This preliminary evaluation of the effects of soil depth over coal refuse and fertilizer application rates on vegetation establishment and acid generation within the refuse material indicate that vegetation response is positively correlated with increased soil cover; the addition of fertilizer is beneficial; and sulfide-sulfur compounds will oxidize to form acidic conditions in arid environments.
