[Terrapreta] Durability of charcoal as carbon sink?

[Duane Pendergast]

            I apologize if I mislead.

 

I'm not suggesting we don't need to keep records. It's just that the
accounting system can be simple and does not need any elaboration to account
for degradation of the sinks as other biological carbon sinks such as  low
till farming, or forest growing apparently do.

Sequestration by charcoal thus greatly simplifies the design of an
accounting system as there is no need for complex formulae to account for
sink degradation.

Perhaps true, but in the spirit of endowing future generations it would be
wise to keep durable records of where we sequester large quantities of char.
While I doubt there will be any shortage of records for them to examine,
future researchers might appreciate having to do less expensive field work
to figure out exactly what we've left them with and how we did it.
