absorbed by plants via photosynthesis is deposited by natural processes in
the soil. Large quantities have been trapped over millennia.
practices and composting are cited as means of keeping more carbon in the soil.
fraught with uncertainty though. How much carbon containing plant material
simply decays quickly and returns as carbon dioxide to the atmosphere? Will soil reach an
equilibrium carbon content and then absorb no more? Likely some of you are
involved in advancing the science.
