Carbon sequestration is crucial for mitigating climate change by storing atmospheric carbon dioxide (CO2) in soil and vegetation. This approach is an underlying principle of sustainable soil management, a goal that involves maintaining and enhancing overall soil health for the purposes of agricultural productivity and acting as a storehouse for CO2. Soils are the most important land-based ecosystems that store approximately two-thirds of terrestrial soil organic carbon (SOC). The global SOC pool is estimated to be three times as large as the atmospheric carbon pool and four times larger than the biotic carbon. Implementing specific soil management practices, such as reforestation or afforestation and sustainable agricultural techniques, can increase C sequestration in the soil, leading to greater SOC levels. These farming practices not only capture carbon but also improve soil structure/fertility/water retention while increasing ecosystem resilience overall. On the other hand, human land use changes like deforestation and agricultural expansions have caused a big loss of carbon from soils. Conversion of natural vegetation into croplands is a major driver of SOC loss. However, the implementation of sustainable management and reforestation can multiply SOC to a greater extent. Practices like no-till farming, cover cropping, crop rotation, and the use of organic amendments are all a part of sustainable soil management. These practices have in common that they increase the degree of carbon sequestration by encouraging organic matter stocks to build up and, on the other side, decreasing soil disturbance. Furthermore, reforestation and afforestation activities also increase carbon sequestration in biomass and soil so that these projects have a long-term impact on climate change. There are important environmental co-benefits to carbon sequestration in addition to its mitigation potential of climate change. By reducing atmospheric CO2 levels, it mitigates ocean acidification, protecting marine ecosystems. Moreover, increased SOC benefits improve soil health, biodiversity, and agricultural performance. In conclusion, soil carbon sequestration through sustainable land management is an important and effective strategy to fight climate change and environmental degradation. By adopting effective land management practices, we can improve SOC content, boost soil health, and add to a more resilient and sustainable ecosystem.
