摘要：Terrestrial carbon plays a significant role in mitigation of climate change because it is the second largest store house of carbon. However soil carbon estimation is not common in the forests especially in plantation. Therefore, this study was objectively carried out to assess and compare the soil carbon in public plantation and community planted forests and show variation in soil carbon according to the soil depths. Six plantation areas were selected of Mahottary district. Total 52 sample plots were randomly established on the map of the plantation sites setting the complete random design. After that, the centre point coordinates of each sample plots were recorded and uploaded in GPS. Next, the sample plots were established in the field by navigating the coordinates. Altogether 156 soil samples were collected from three layers specifically 0-10, 10-30 and 30-60cm using soil auger and analyzed in lab using the Walkley and Black method. The result showed that the highest soil carbon was found about 79.13 t ha-1 in Shreepur public plantation while it was the lowest about 15.44 t ha-1 in Jogikuti community planted forest. The soil carbon was the highest in 0-10cm depth, this was followed by soil carbon of 10-30cm and least value was found in 30-60cm. In fact, the estimated records of soil carbon was the highest about 31.46 t ha-1 in Shreepur public plantation in 0-10cm while it was the lowest about 3.45 t ha-1 in Jogikuti CPF in 30-60cm. In fact, soil carbon decreases according to increasing soil depth in a profile. The t-test showed that, there were significant differences in soil carbon of same aged plantations. The soil carbon stock was richer at plantation sites close to natural forest and edge of the pond in comparison to sites of river bank.
