Abstract/Description: | Plantation forestry emerged as a potential low-cost tool for mitigation of climate change through enhanced soil carbon sequestration. Plantation forestry has definite impact on soil aggregates through better organic carbon dynamics. In view of this a study was carried out in a 4-year old Eucalyptus tereticornis plantation to evaluate the impact on soil aggregate fractions and carbon dynamics in partially reclaimed sodic soil. Results indicated that most of the soil quality enhancing properties concentrated at the soil surface (0-15cm) compared to other soil depths. In general, total carbon (TC), total organic carbon (TOC) and oxidizable organic carbon (OC) decreased with soil depths, whereas, no such pattern was observed in case of total inorganic carbon (TIC). Mean TC was 11.9 g kg-1, which was 16.7% and almost 7 times higher than TOC and TIC, respectively. Total water stable aggregates were found to be 10.9 % higher in surface soil (0-15 cm) than in sub-surface soil (15-30 cm). Aggregate associated carbon of meso-aggregates was more than 5 and 2 times higher to those of the ‘silt+clay’ and microaggregates, respectively. Block plantation of Eucalyptus tereticornis might be a better option for mitigating greenhouse effects by sequestering atmospheric carbon and improving soil aggregate stability, which improves soil health and enhances the productivity of the system. |
