Abstract
Different water management and fertilizer application could lead to an increase in aboveground
soil temperature. This will lead to higher emission of greenhouse gasses. This study investigates
the effect of fertilizer application and irrigation management on the dynamics of aboveground
temperatures in a paddy field. Temperature measurements were recorded at four periods, before
the application of fertilizer (A), a day after (B), two days after (C), and three days after the fertilizer
application (D). Two water managements were also employed, Control (continuous flooding) and
Alternate Wetting and Drying (AWD). The result showed that the fertilizer application prompted
an immediate temperature increase of 1.58% from A to B, followed by a gradual decline of about
8.35 to 10.88% over the subsequent period of measurements (B to D). In the context of irrigation
management, the Alternate Wetting and Drying (AWD) treatment had 0.58% higher temperature
compared to the Control, with greater stability. These results underscore the complex interplay of
factors influencing temperature responses in rice cultivation. Tailored agricultural practices are
essential for optimizing temperature-regulated strategies. Therefore, long-term monitoring is
recommended for a comprehen
