Abstract/Contents:"Nitrogen (N) mineralization from 3 composts was determined in the laboratory. The composts were PBC, made from yard trimmings and biosolids, BED, made from municipal solid waste (MSW), and EC, made from yard trimmings without biosolids. Ammonium and nitrate N were determined in monthly CaCl(@2) leachates of compost/sand mixes (150cc/300cc) in columns. Six replicates of each compost were incubated at 20, 30, and 40C for one year. The PBS, BED, anb EC composts contained, 18.7, 13.7, and 9.9 g N kg(^1), respectively. In general, over 90% of the percolate N was in the nitrate form. Mineralized N generally increased with increasing temperature. At 30 C, total N mineralized during the one-year period was 10.7, 5.8, and 9.0% of the N contained in PBC, EC, and BED composts, respectively."
