Go to this link just above. It explains what the Yeomans Keyline Plow is all about. And it is about increasing soil fertility cheaply. In other words creating humus, and humus is the “soil carbon” in “soil carbon sequestration”.
This is an extract from the Yeomans Plow web site: “For you, on the farm, on the property, on the ranch there is one thing that you can do much better than nature can. And you can do it in an instant.
You can create the abundant space needed to allow soil life to do its thing, to massively proliferate. One deep pass with a subsoil plow that produces minimum disturbance of soil layers and the perfect microbe and earthworm housing estate is created. The soil fertility creation process can thus be speeded up, in many cases a thousand fold. What took centuries can be done in two or three seasons. And improvements can continue to produce soil to unprecedented fertility, for decades.”
