Revegetation of an abandoned coal washing site

western Kentucky. The entire site was treated with fertilizer and lime to add nutrients and neutralize the soil pH. Four main treatments and control plots were established. The treatments included bark; straw and manure; bark, sawdust and manure; and a mixture of sewer sludge and kiln dust. Plots were also treated with a water absorbing synthetic polymer. All plots were seeded with various grasses, legumes, and black locust. The site was measured in 1992 after three growing seasons for woody plant biomass and percent ground cover. Significant differences in both woody plant biomass and percent ground cover were found between the treatments. Various reclamation techniques were applied on an abandoned coal washing pond.
