Sequestered Organic Carbon Status in the Soils Supporting Different Tree Plantations in Uttarakhand State of India
Journal Title: International Journal of Research in Chemistry and Environment (IJRCE) - Year 2012, Vol 2, Issue 2
Abstract
The IPCC has identified creation and strengthening of carbon sinks in the soil as a clear option for increasing removal of CO2 from the atmosphere and has recognized soil organic carbon pool as one of the five major carbon pools for the LULUCF. Tree plantation has definite effect on soil properties and dynamics of carbon store in soil. Plantations are good sink of carbon to facilitate carbon store in the soil as well as in biomass. SOC pool was therefore, estimated under different block tree plantations in Uttarakhand state of India. SOC pool under C. cashmeriana was maximum (66.32 t ha-1) followed by Eucalyptus spp. (46.39 t ha-1), P. roxburghii (43.60 t ha-1), T. grandis (42.93 t ha-1), D. sissoo (37.67 t ha-1) and P. deltoides (31.41 t ha-1). A large share of SOC was contributed by C. cashmeriana plantation (24.72 %), followed by Eucalyptus spp. (17.29 %), P. roxburghii (16.25 % ) T. grandis (16.00 %), D. sissoo (14.04 % ) and the least share was held by P. deltoides (11.71 %). One-way ANOVA indicated that SOC pool between the plantations was significantly different at 0.05 level. The mitigation potential of C. cashmeriana was more than two times as that of P. deltoids
