About Dark Earth
- Terra preta soils were first discovered and described in the 1870s by American and European travelers in the lower Amazon region who observed the highly fertile and extensive black soils cultivated by former Confederate settlers. However, the anthropogenic origins and significance of these soils were not widely recognized until international conferences in the early 2000s brought together scientists from different disciplines. - While terra preta had been noted and studied since the late 19th century, it was not until the 1970s that systematic mapping and analyses of the soils’ carbon content and cultural origins began providing evidence that terra preta was deliberately created by indigenous populations over centuries through charcoal amendments to existing soils.
