Soil-based carbon sequestration is a way to remove CO2 from the air and store it somewhere it can’t easily escape: in soils, which store carbon in the form of broken-down plant matter.
Soil carbon sequestration (SOC) is the process of transferring CO2 from the atmosphere into the soil in the form of organic carbon. This process begins with photosynthesis, where plants convert atmospheric carbon dioxide into organic compounds. These compounds are then incorporated into the soil through plant residues and root exudates.
Enhanced soil carbon sequestration can be achieved through various management practices, like cover cropping, no-tillage, crop rotation, and organic matter incorporation, which stimulate plant growth and soil microbial activity.
The long-term conversion of grassland and forestland to cropland (and grazing lands) has resulted in historic losses of soil carbon worldwide but there is a major potential for increasing soil carbon through restoration of degraded soils and widespread adoption of soil conservation practices.
Potential of soil carbon sequestration to mitigate climate change, along with principles and practices for enhancing soil carbon pool and increasing its mean residence time (MRT).
Soil carbon sequestration is a process in which CO 2 is removed from the atmosphere and stored in the soil carbon pool. This process is primarily mediated by plants through photosynthesis,...
Sustainable soil carbon sequestration practices need to be rapidly scaled up and implemented to contribute to climate change mitigation. We highlight that the major potential for carbon...
Soil organic carbon (SOC) sequestration has been suggested as an economically viable option for natural climate change mitigation with multiple co-benefits. In fact, increasing the amount of carbon in the soil to mitigate climate change has long been proposed, since the early 1990s, as was recommended in the 1995 IPCC report.
Soil carbon is important to land-based efforts to prevent carbon emissions, remove atmospheric carbon dioxide and deliver ecosystem services in addition to climate mitigation. Diverse...
Grasslands store approximately one third of the global terrestrial carbon stocks and can act as an important soil carbon sink. Recent studies show that plant diversity increases soil organic carbon (SOC) storage by elevating carbon inputs to belowground biomass and promoting microbial necromass contribution to SOC storage.
