This study investigated the total Soil Organic Carbon (SOC) density and its distribution under two different forest types considering the change in carbon with elevation in two different depths of the soil in Nahi Gewog, Bhutan. This work will serve as baseline data for further research on soil carbon density.
The soil, being one of the carbon pools, hosts the largest terrestrial carbon and plays a crucial role in the global carbon balance by regulating the exchange of greenhouse gases with the atmosphere. The Earth is facing increased pressure from emission of Greenhouse gases which leads to change in natural climate system from good to worse. Bhutan is considered as carbon neutral country and the country has large masses of forest soil which have huge potential for carbon absorption than to release into atmosphere which would otherwise attributed to Global warming.
