Soil carbon is simply carbon that is found in soils. All soils contain some amount of carbon—remnants of living matter that have been degraded over time.
Sequestration refers to practices that can take excess carbon and store it somewhere. In the case of soil carbon, it is sequestered by those practices that put more carbon into the soil than is released through normal processes of decomposition.
