Partially burned material a boon to plants: Sandy (Oregon) resident sees biochar as a way to fertilize and capture carbon
By Garth Guibord, The Gresham Outlook, Mar 30, 2007

When most people see a pile of sticks and wood, all they see is sticks and wood. Sandy resident Paul Elmore, 39, sees possibilities. He sees biochar

Terra Preta de Indio
Johannes Lehmann. Soil Biogeochemistry, Cornell University January 2007

"Terra Preta de Indio" (Amazonian Dark Earths; earlier also called "Terra Preta do Indio" or Indian Black Earth) is the local name for certain dark earths in the Brazilian Amazon region. These dark earths occur, however, in several countries in South America and probably beyond. They were most likely created by pre-Columbian Indians from 500 to 2500 years B.P. and abandoned after the invasion of Europeans (Smith, 1980; Woods et al., 2000). However, many questions are still unanswered with respect to their origin, distribution, and properties.

Introduction: Bio-char: the new frontier
Johannes Lehmann, Soil Biogeochemistry, Cornell University

Inspired by the fascinating properties of Terra Preta de Indio, bio-char is a soil amendment that has the potential to revolutionize concepts of soil management. While "discovered" may not be the right word, as bio-char (also called charcoal or biomass-derived black carbon) has been used in traditional agricultural practices as well as in modern horticulture, never before has evidence been accumulating that demonstrates so convincingly that bio-char has very specific and unique properties that make it stand out among the opportunities for sustainable soil management.
