I wonder if anyone has tried to clean up contaminated land with biochar?
What effect would it have on heavy metals or oil based contaminants? Lots
of prime real estate worthless because of trace contaminants.

This is to also answer the two following messages from yourselves. I did
not find them helpful - as they assume the only economics relate to the
carbon credit. They assume nothing (repeat nothing) about the value to the
user in outyear ag benefits. Tell me how farmers in the world will react to
news that (for example) land worth zero today can be brought up to a
productivity level the same as other existing ag land nearby (same rainfall
etc.)
Let's say that land can, after applying biochar be worth $500/ha rather
than $0/ha. If those farmers have a discount rate of 5% or 50% will make
a big difference on how much they will be willing to spend per tonne of
biochar and how many tonnes per ha (which could be in rows or holes - not
uniformly scattered). Which discount rate are you using for these out-year
benefit computations?
You can't prove biochar is worthless by talking to this list only about
credits of $6/tonne CO2.
