Amazonian Terra Preta

Definition

Amazonian Terra Preta, or 'black earth,' refers to a type of fertile soil found in the Amazon Basin, which was created by ancient Indigenous communities through the intentional mixing of charcoal, bone, and organic matter. This unique soil has remarkable properties that enhance agricultural productivity and retain nutrients, showcasing the advanced ecological knowledge of Indigenous peoples in managing their environment sustainably.
