"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.

“Somewhere, Something Incredible Is Waiting To Be Known”
Words of a brilliant and wise man, Carl Sagan. And indeed, some of the things
we will be talking about over the next two days are incredible and have only recently
become known. Amazonian dark earth is incredible for its own sake, but even more so
because of its implications for sustained cultivation, energy generation, global

Amazonian Dark Earths: Origin, Properties, Management

This book publication emerged from a meeting in Benicassim, Spain, in 2001. A group of enthusiastic scientists from diverse backgrounds decided that it is time to present a comprehensive overview over research on the so-called "Terra Preta de Indio", or Amazonian Dark Earths. Authors were invited to cover a wide variety of aspects around these fascinating soils, and met what became the first International Workshop on Terra Preta de Indio, in Manaus in July 2002. The frequent interactions and the workshop meeting ensured that this publication became a major text book on Amazonian Dark Earths. It is published by Kluwer Academic Publishers in The Netherlands
