Fig. 7. Time course of CH₄ oxidation in paddy soils pretreated by varying water content and incubated under the same historic water condition. (a) Soil E (Epiaquepts); (b) Soil H (Hapludults); I, II, III, IV, and V represent air-dry water condition, 25 to 35, 50 to 60, 75 to 85% of soil water-holding capacity and flooding, respectively, during non-rice-growing season. Bars indicate ± one standard deviation.
