บทคัดย่อ (EN): Methane (CH4) is one of the most important greenhouse gases having a significant impact upon global warming. Today, paddy fields are a major source of methane production. The objective of our experiment is to investigate whether sulfate fertilizer can reduce the amount of methane emissions from the paddy field into the atmosphere, while maintain or increase fertility of the paddy soil, and the rice production of Chainat1. The experi-mental plan was structured using the Randomized Complete Block Design (RCBD), consisting of four treatments: 1) Incorporation of rice stubble without the usage of sulfate fertilizer, 2) Incorporation of rice stubble using sulfate fertilizer, 18 kg SO4/rai, 3) Incorporation of rice stubble using sulfate fertilizer, 32 kg SO4/rai, and 4) Incorporation of rice stubble using sulfate fertilizer, 48 kg SO4/rai. Sulfate was used in the form of fertilizer 16-20-0 (42% SO4). Results showed that there was no significant effect of sulfate on the physical and chemical properties of soil after harvest. The sulfate, at the rates of 18, 32 and 48 kg SO4/rai, insignificantly reduced the amount of methane emis-sions and released 19.3, 14.2, and 11.6 kg CH4/rai. Moreover, sulfate also reduced the quantity of Global Warming Potential (GWP) in decreasing order of 443.9, 326.6, 266.8 kg/rai, respectively; though comparatively insignificant. Additionally, the application of sulfate fertilizer increased rice production two-and-a-half times (1001 to 1094 kg/rai) that of the control without sulfate fertilizer (476 kg/rai). We have concluded that the application of sulfate fertilizer boosts rice yield, but could not mitigate methane emission or GWP in fine textured paddy soil.
