Carbon sequestration (CS), hiding Cabon in soil, is considered a way by which the occurrence of global warming could be reduced. However, it would be somewhat difficult to quantify the net CS that happens for a given period. Adding C into soils promotes solid organic matter, microbial activities, development of soil structure, etc. in soils. Benchmarking and increasing C storage in soils over time would enable quantifying or generating a realistic value. Any experience and suggestions to quantify CS are appreciated.
