And that brings us to why I am skeptical about the carbon
sequestration premise. The carbon gets into the soil through the
plants. It gets down to the roots. But the next crop or the next crop
after will be eating the nutrients the microorganisms produce when
they are eating those roots. Why should the carbon stay down there?
