I posted this this in r.g and r.g.e and then wondered if any of you on
your side of the planet have done this or have experience with this, as
you seem to be ahead of the curve. The more I read, the more excited I
become about it. I'm particularly enthused about the long term and
persistent aspects of this.

These FUs added some info..seems there is a shit-ton of info and study
being done. Benefits seem to go beyond soil fertility.

If it is charcoal, then the role is just as a holder for the
nutrients/minerals or whatever else was mixed into it before hand.

If it is char, aka not fully combusted, then there are some nutrients in
the materiral isself (as opposed to trace minerals, etc in charcoal).

I think Terra Pretta is some stuff created from coal that they are trying
to give a name to. my thoughts are that it is a way to turn rubbish coal
into a salable product.
