Production rate of CO2 from incubated paddy soil under aerobic condition and that of CH4 under anaerobic condition were measured for periods of more than 100 d. The incubations were undergone at warmer temperature than real condition of rice paddy to \"accelerate\" SOM decomposition several times faster than the real condition. Both production rates of CO2 and CH4 showed rapid decrease to 10^-10 kg-C (kg-dry soil)-1s^-1 for 10 d just after starting the incubations, and then they decreased moderately. For CO2 the variations in carbon isotopic ratios (\u03b413C, \u039414C) were also measured during the incubation. At first the \u03b413C of SOM-derived CO2 was ca. -22 \u2030, and it rapidly decreased to less than -28 \u2030 to become close to that of SOM (-29.2 \u2030). The variation in \u039414C of CO2 also showed slightly higher value for the fist several days than those for the period after 20 d. However, all of \u039414C measurements were less than 0, and this means their 14C ages were older than 1960s, the era of atmospheric nuclear weapon testing, apparently. Since these apparent ages are inconsistent to the time scale of SOM decomposition measured in this study, older SOM as well as modern one might be attributed to source of the CO2.",
