That is where I think we disagree. I think that we specifically SHOULD
NOT tie them together. Let them each rise or fall on their own merits.

Waste biomass, on pyrolysis, can yield biomass char. This biochar has
(at least) two uses... charcoal as fuel, charcoal as a soil amendment.
What happens if I can sell charcoal for fuel (or other uses) at $300 per
tonne, and if a Farmer can only afford to pay me $50 per tonne for
biochar to add to soil? Are we to stop selling biochar to energy (or
other) applications because the Farmer will not pay more than $50 per
tonne? The purpose of this List is to find ways to promote char
additions to the soil, if it is sensible to do so, NOT to attempt to
regulate the biochar industry.

And that is why I feel they specifically SHOULD NOT be tied together. We
(at least I) don't know what a Farmer can afford to pay for biochar to
add to the soil. Perhaps "New Terra Preta" is uneconomic. If it was
uneconomic, then tying the development of a biochar industry to
additions to soil would kill it dead.
Perhaps they might work out wonderfully well together. For example, sell
big pieces of charcoal to the heating market, and sell the fines into
the soil amendment market. I do not know how things will want to "shake
out", and accordingly, I think it would be a bad thing to "tie them
together".
If you want to encourage the use of biochar for soil amendment purposes,
then work on getting a subsidy to encourage the use of biochar for soil
additions. Imagine how people would be racing to their retorts if the
Gummint was giving a subsidy equivalent to the subsidy now being given
to support ethanol!
Best wishes,
Kevin
