C-14 is an effective tracer in investigating the carbon dynamics in the environment. In this study, the measurements of C-14 in soil organic matter (SOM) in a deciduous forest were used to determine the turnover time and CO $_{2}$ production rate from SOM. In addition, monthly measurements of carbon isotopic ratios in soil-respired CO $_{2}$ and atmospheric CO $_{2}$ were conducted to characterize the seasonal variation of the contribution of each CO $_{2}$ source, such as SOM decomposition and root respiration.
