In a laboratory experiment, mineralization rate of soil organic nitrogen under submerged conditions using 15N tracer was studied. Mineralization rate increased with temperature. Cumulative amount of nitrogen mineralized was expressed as the product of effective temperature and the duration of incubation. The minimum threshold temperature was nearly 10℃ in the range of 20-30℃. Air-drying of soil before submergence promoted mineralization within several weeks after submergence.
