Soil carbon sequestration as a climate change solution

Aug 30, 2021·Unfortunately, the rate of accumulation of soil organic matter is usually much slower than its loss, and substantial amounts of energy must be used to increase carbon sequestration in most soils. Thus, suggestions that we can mitigate the impact of fossil fuel combustion by increasing carbon storage in soils are bogus.
