Beef-cattle manure collected from unpaved dirt feedlots has a significantly decreased energy-production potential due to low organic content and dirt contamination. In laboratory batch fermentors beef-feedlot manure of various ages was digested. Compared with fresh manure-gas production at 100%, aged manure produced 16-73% of the gas/kg of volatile solids added. More than 1/2 of the N was lost after the manure had aged 3 months. Economic benefits of CH/sub 4/ and N recovery from manure of different ages are discussed.
