[Gasification] biochar to sequester carbon

[Tom Miles]

Reg,

Your find discussions of this an related articles on the terra preta
discussion list and website that we started in January.
http://terrapreta.bioenergylists.org/
http://bioenergylists.org/pipermail/terrapreta_bioenergylists.org/

You will find links there for Cornell where Lehmann is and other charcoal
research. Some people on the discussion list have started their own farm and
garden tests of charcoal, on arid soils in Guinea and Australia, on alkaline
soils in India, in China, "somewhere 20 miles south of Lake Erie, USA," in a
nursery in Washington, etc.

We're all learning what the agronomic value of the charcoal might be for
different soils and plants. The results are not yet clear. At best it would
be a good use for char from gasifiers.

I trust every one on the list has read this paper?  Comments would be 
appreciated.
