Sure, I agree and know that you all are working on the specifics (which will
also vary according to the circumstance). My point was that carbon amendment
can start right away supported by carbon sequestration credits and that part
of the requirement would be to record and report the results. Think of it as
a gigantic experiment that causes no harm but generates and incredible
amount of data, etc, etc. I think you could start to find out what works,
where and how pretty fast and keep refining it over time.  Everyone learning
together and getting paid for it. What a concept!
