Description: Study on active and labile carbon-pools can serve as a clue for soil organic carbon dynamics on exposure to elevated level of CO"2. Therefore, an experimental study was conducted in a Typic Haplustept in sub-tropical semi-arid India with wheat grown in open top chambers at ambient (370@mmolmol^-^1) and elevated (600@mmolmol^-^1) concentrations of atmospheric CO"2. Elevated atmospheric CO"2 caused increase in yield and carbon uptake by all plant parts, and their preferential partitioning to root. Increases in fresh root weight, volume and length have also been observed. Relative contribution of medium-sized root to total root length increased at the expense of very fine roots at elevated CO"2 level. All active carbon-fractions gained due to elevated atmospheric CO"2 concentration, and the order followed their relative labilities. All the C-pools have recorded a significant increase over initial status, and are expected to impart short-to-medium-term effect on soil carbon sequestration.
