The conference in Georgia sparked a lot of interest.

Later on, in 2007, an Internet discussion list was established. Individuals involved tirelessly spread information on the concept and try to coordinate experimental work on biochar production and soil enhancement studies.

Now, the concept  has “gone viral”. Many enthusiasts are trying it out the concept in their backyards and farms.

Internet searches in 2004  came back essentially empty. Now a search on “Terra Preta” or “Charcoal in Soil” yields hundred of thousands - or more - “hits”.

There is so much information it’s  difficult to separate dreams from reality.
