Abstract:
Soil carbon holds a key part on the Carbon-cycle, as at a 1 m depth, soils store the largest terrestrial carbon pool. Therefore, carbon sequestration could potentially mitigate climate change. In this context present investigation of soil carbon pool was carried out at Tanda, Bhakda and Pipalpadao forest ranges of Tarai Central Forest Division, Western Circle, Uttarakhand, India during 2013-14. Random sampling was done in all the three forest ranges. Total soil sampling was done at 23 sites of Tanda, Bhakda, and Pipalpadao range in the month of February 2014. The average carbon values for Tanda, Bhakda and Pipalpadao ranges were 1.290%, 1.277% and 1.205% respectively at 0-15cm depth of soil profile and 1.047%, 1.053% and 1.007% respectively at 15-30 cm depth of soil profile. The spatial interpolation method, IDW (Inverse Distance Weighting) used to estimate soil organic carbon of unsampled locations with Geographical Information Systems (GIS) modeling. Tanda, Bhakda, and Pipalpadao forests were having soil organic carbon 0.303 million ton, 0.302 million ton and 0.284 million ton respectively.
