[Terrapreta] Assaying carbon levels in soil

[Rick Davies]

You could measure how much you were "pouring in", but how would anyone
verify that, except by having access to before and after measures of the
carbon content of the same soil? Or by being able to compare carbon content
in soil where carbon was (reportedly) added and other soil nearby where
carbon had not been added (and which otherwise appeared to be the same soil
type)
