Limited information is available on the rate of N release and ammonia volatilization from Nitamin, a new N fertilizer developed by Georgia Pacific. One laboratory study was conducted to study N mineralization and ammonia volatilization from urea, urea-ammonium nitrate solution, and Nitamin surface applied at 100 kg N/ha. Soil was packed in acrylic cylinders, thatch was placed on the surface of the soil, and fertilizers were placed on the thatch. The cylinders were placed in a flow-through system in an incubator at 25^oC and air circulating over the soil was bubbled through acid traps to capture the ammonia volatilized. Destructive sampling was carried out periodically for a total incubation time of 180 days. Results showed that urea lost more ammonia (24%) than urea-ammonium nitrate and Nitamin, which were not different from each other (11%). A second laboratory study was carried out to evaluate N mineralization when urea and Nitamin are applied in a band in the soil. The fertilizers were applied at 100 kg N/ha and the incubation was carried out for 180 days with periodic, destructive samplings for inorganic N determination. In general, the rate of N mineralization was greater for urea than for Nitamin.
