Summary, etc. The soil CO 2 effl ux is recognized as one of the largest fl uxes in the global carbon cycle, and small changes in the magnitude of soil respiration could have a large consequence on the concentration of CO 2 in the atmosphere. In this study, we analyzed the soil organic carbon (SOC)stocks and CO 2 effl ux from soil respiration in a tropical secondary forest succession grown after abandonment of swidden agriculture in Southern Mexico. The study was conducted in a chronosequence of semievergreen tropical secondary and primary forests in the southern part of Yucatan Peninsula, Mexico. We collected soil samples (up to 30 cm depth)from 32 carbon monitoring plots and analyzed these for physical and chemical soil properties. Soil respiration measurements were carried out by using PP systems EGM-4 (an infrared gas analyzer). Analysis of variance (ANOVA), correlation, and regression was performed to test differences between forest age groups as the independent variable and soil respiration, organic as well as inorganic carbon in soil. Contrary to the hypothesis, SOC in the mineral soil horizon did not increase with forest age. Soil CO 2 effl ux did not correlate to soil organic carbon, it rather correlated to carbonate concentration in the soil. Higher CO 2 effl ux in carbonate rich soils can be explained probably by the faster decomposition but the slower ultimate mixing of organic matter in mineral soils of carbonate origin. However, it needs further investigation in separating soil CO 2 effl ux into autotrophic, heterotrophic, and abiotic fl uxes to better understand the role of carbonate soils in atmospheric CO 2 exchange.
