Definition. Carbon-storing natural feature (such as a forest or the land mass) that exchanges carbon with other reservoirs. A reservoir from which no outflow of carbon compounds takes place is called carbon sink.
Soil carbon is the generic name for carbon held within the soil, primarily in association with its organic content.Soil carbon is the largest terrestrial pool of carbon, containing 2,200 gigatonnes (Gt) of it. Humans increasingly influence the size of this pool.Soil carbon plays a key role in the carbon cycle, and thus it is important in global climate models.oil carbon plays a key role in the carbon cycle, and thus it is important in global climate models.
