In the Mid-Atlantic region, intensive animal production produces manure nutrients in excess of crop needs, increasing the likelihood of transport to water bodies and degradation of ecosystems and water quality.  In this same region, 150 years of extensive coal mining has severely degraded mined land and impaired streams.  Excess manure could be utilized in mine reclamation, but the large application rates required for successful revegetation could result in significant nutrient discharge.  This greenhouse experiment investigated two approaches to minimizing the potential for nutrient leaching of poultry manure: composting and C/N ratio adjustment.  Columns of mine spoil were amended with fresh manure, manure mixed with short fiber paper mill sludge (C/N ratios of 20 - 40) and 3 rates of composted manure.  Mixes were planted with switchgrass (Panicum virgatum) and leached every four weeks to assess leaching loss of macronutrients.  Each level of compost addition increased switchgrass growth over the unamended spoil and spoil amended with limestone and inorganic fertilizer.  Fresh poultry manure without paper mill sludge exhibited the highest leaching of NO₃ (192 mg column^-1) and P (12 mg column^-1).  In columns with compost, NO₃ and P leaching was minimal, although P decreased by only four fold in the higher levels of compost from fresh manure P levels.  In treatments combining fresh poultry manure and paper mill sludge, increasing the C/N ratio resulted in increased growth of switchgrass and large decreases in the amount of NO₃ and P leached compared to the fresh manure treatment without paper mill sludge.  These results indicate that compost treatments were most effective at limiting NO₃ loss but were not as successful at limiting P loss while co-application of manure with a high carbon material could provide equivalent or superior revegetation results while controlling nutrient loss via leaching.
