Summary
At temperatures of 20°, 30°, 40°, 50° and 60°C in a Gangetic alluvial soil (G soil, pH 7.6) N-mineralization and nitrification increased with temperature up to 40°C and mineralized N accumulated entirely as nitrate. At 50° and 60°C mineralized N was relatively low and no nitrification occurred. In the Red soil (R soil, pH 5.2) mineralized N increased with temperature up to 40°C, was somewhat less at 50°C and was at a maximum at 60°C. Nitrification was maximum at 30°C but did not occur at 50° and 60°C. In the G soil C-mineralization increased considerably with temperature, whilst in the R soil there were only small differences due to temperature.
