1994a). 5 kg soil without rice straw (the other side), Treatment 5 - 3 kg soil without rice straw, and Treatment 6 - 3 kg soil with 18 g rice straw. In Treatment 4, soils were separated vertically by a plastic plate that had a Vshape cut on the top. A seeding was transplanted over the plastic plate to develop roots from tillers into both sites equally. Fig. 6. Percentage distribution of the total amount of CH4 emitted in the first and the second halves of the growth period Dynamics of Methane in Rice Fields 39 Methane emission rates were measured by the closed-chamber method (Kimura et al.

This suggests that CH4 production in a submerged soil is accelerated by a higher percolation rate. Cumulative CH4 fluxes were divided into early and late stages at the end of July, when rice plants reached the panicle initiation stage (Table 4).

Pathumthani, and rice-straw compost at Surin). A closed chamber method was used to measure the CH4 emission flux from the rice fields (Minami and Yagi 1988; Kimura et al. 1991b). Methane Emissions from Thai Rice Fields Temporal variations in CH4 flux from a ricefield at Suphan Buri are shown in Fig. 3. The CH4 fluxes were always higher in the afternoon than in the morning, which correlated with the increase in the soil temperature of the surface layer of the soil. Soil temperature measured at a depth of 2 cm ranged from 28 to 33 °C during the dry season and from 21 to 34 "C in the rainy season.
