| 内容記述 | The 14C-containing gas production ratios were determined by batch tests using 142 agricultural (upland and paddy) soil samples. Each of the soil samples was suspended in deionized water containing either [1-14C] sodium acetate or [1,2-14C] sodium acetate and shake-incubated for 7 days. Production ratios, on average, were 68.6% for [1-14C] sodium acetate and 59.1% for [1,2-14C] sodium acetate. From the results, the 14C-containing gas production ratio for [2-14C] sodium acetate was calculated to be 49.6%. The carboxyl group of sodium acetate, therefore, is easily released as gas in Japanese agricultural soils. Land use also affected the 14C-containing gas production. The production ratios of upland soil samples were significantly lower than those of paddy soil samples. | |||||
