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.
