ABSTRACT
Carbon sequestration and maintaining it in an ecosystem level has been highly appreciated to keep the atmospheric carbon concentration up to a considerable level to minimize the risks of climate change. Research result from northeast India suggested that degraded soils under managed rubber plantations have considerable potential for carbon sequestration. The rate of soil carbon sequestration in terrestrial ecosystems is greatly influenced by its vegetative cover. Changes in soil organic carbon (SOC) stock in forest soil due to land use change may induce a large effect in atmospheric carbon concentration. The SOC sequestration rate for different aged plantation was calculated from SOC stock difference between any two plantation ages divided by differences in age of the plantation. Thus, for each study site, a total of 36composite soils were prepared for subsequent air drying. Air dried soils were sieved through 100-micron mesh for SOC concentration analysis.
