|I finally found
and went to a relevant conference, in
Georgia. About 50 people attended including archeologists, soil scientists,
and experts in bioenergy.
|I learned that
archeologists had long known of an ancient civilization in South America that
apparently incorporated charcoal in soil with a variation of slash and burn
agriculture. Very rich soil known as Terra Preta resulted. It is still there hundreds of years after the
civilization collapsed – possibly from disease introduced by European
had gathered to discuss the implications on
carbon dioxide mangement as well as soil enrichment.
|The sense of
discovery at this little conference was palpable. It seemed to me these
people were onto something useful.
