The relentlessly increase of atmospheric carbon dioxide (CO2) concentration due to release from different sources leads to global warming and climate change which are a cause for great concern demanding in-depth research on CO2 emission from soil under different forest cover. Forest cover can reverse the increasing CO2 in the atmosphere, thus, contributes to mitigate climate change. Forest stored about half of the organic carbon (C) contained in terrestrial ecosystems. The role of forests has a great impact on the global biogeochemical cycles and in particular, the carbon cycle. Larger parts of the global C stock are stored in forest ecosystems. So, identifying the tree species in a forest with high SOC, soil organic carbon stocks (SOCS) and high C sequestration with low CO2 emission is a priority for mitigating the global climate change. Carbon sequestration in forest occurs in both aboveground and below ground biomass. But, the below ground C sequestration was quite low in comparison to the above ground. The rate of C sequestration in Schizostachyum pergracile dominant forest was Mg ha–1 year–1 whereas for Dipterocarpus tuberculatus dominant forest was Mg ha-1 year-1 . The annual organic C input (gCm-2 year-1 ) as litter fall of forest dominated by Quercus serrata + Schima wallichii and Ficus virens + Cinnamomum zeylanicum, were and respectively. | Soil organic carbon responses under different forest cover of manipur: A review
