Introduction
Carbon sequestration is the removal and long-term storage of atmospheric CO2 in the ocean, geological landforms, soils, and biotic pools. These storage forms can act as a carbon source or sink; the size of the flow of CO2 to and from the atmosphere into oceans, soil and geologic landforms will determine if they will become carbon sources or sinks. When carbon is stored in soils, it is called soil carbon sequestration (SCS) and about 75% of carbon sequestered on land is stored in soil (Powlson et al, 2011). The carbon is then stored either as soil organic or inorganic carbon and about 46% of vegetative carbon and 33% of soil carbon is found in the tropical rain forest (Fisher and Binkley, 2011).

SOC regulates the charge density for cation exchange, moderates soil temperature and buffers the emissions of greenhouse gasses from the soil into the atmosphere …show more content…
These practices include reducing erosion, conservation tillage, extended crop rotation, integrated management practices, addition of bio solids, improved fertilization, application of organic manure, improving biodiversity (biomass), afforestation, elimination of bush fallow, precision farming, liming, conversion from tillage plough farming to non-tillage plough farming and restoration of degraded soils, (SCS,2016).Conservation tillage decreases disturbance, improves structure, reduces bulk density, and improves infiltration rates (improved infiltration rates enhance soil moisture) (Lal,2008). While the restoration of degraded soil improves organic matter accumulation, and reduces CO2 emissions, it also improves water quality and biomass accumulation (Powlson et al, 2011). Uncultivated soils have more soil organic carbon compared to cultivated
