Radiocarbon (14C) partitioning ratios in the soil solid, liquid, and gas phases was determined by batch sorption experiments using 63 paddy soil and 79 upland soil samples to understand the behavior of 14C in agricultural fields. The mean 14C partitioning ratios for all agricultural soil samples were 35% for the soil solid phase, 5% for the liquid phase, and 60% for the gas phase. A comparison of the 14C partitioning between paddy and upland samples showed significant differences. This difference was caused by soil solution pH. Land use would affect the behavior of the 14C as the sodium acetate form.
