The Establishment and Persistence of Grasses on Acid Gob Amended with Sewage Sludge and/or Limestone

Description
Gob ( coal refuse), which contains pyritic materials, produces sulfuric acid when wetted and oxidized. The acidity together with droughtiness and high surface temperatures create a complex problem for revegetation. Three grasses (reed canarygrass, Phalaris arundinacea L.), tall fescue, ( Festuca arundinacea Shreb.), and redtop, (Agrostis alba L.) were established on an acid gob site void of plants at the Will Scarlet Mine, Peabody Coal Campany, Williamson County, Illinois U.S.A. to evalute the effets of soil amendments. Treatments of sewage sludge to 30 and 60 cm depths of 225 and 450 Mg ha-1 per 30 cm depth, 225 and 450 Mg ha -t sewage sludge plus 45 Mg ha -t limestone for 60 cm depth and 45 and 90 Mg ha-1 of limestone per 30 cm depth were applied. Deep incorporation (30 and 60 cm) of sewage sludge and/or limestone in gob increased soil pH resulting in successful grass establishment and maintenance. The grass canopy cover effectively controlled soil erosion and water pollution. The grass did not accumulate heavy metals to levels considered potentially toxic to livestock. Deep incorporation of sewage sludge and/or limestone is a feasible method for revegetating acid gob without the addition of a soil cover.
