The mineralization of ureaform in the soil has been observed during the three weeks following application in a small plot of a banana ( Musa Cavendishii , var. Cavendish) plantation at two different seasons of the year. In the cooler season ammonium and nitrite accumulated and persisted for 2 weeks. In the warmer season, only ammonium accumulated during 2 days. The rate of mineralization, calculated as a first‐order reaction, was greater at the higher temperature, but the rate constants were about 10 times greater in the field than in previous laboratory experiments. The reasons for this are probably changes in microbiological activity and mineralization of nitrogen from sources other than the fertilizer.
