A new hypothesis for the origin of Amazonian Dark Earths
Here, we report new data from a well-studied ADE site in the Brazilian Amazon, which compel us to reconsider its anthropic origin. The amounts of phosphorus and calcium—two of the least abundant ...
A new hypothesis for the origin of Amazonian Dark Earths
Abstract. Amazonian Dark Earths (ADEs) are unusually fertile soils characterised by elevated concentrations of microscopic charcoal particles, which confer their distinctive colouration. Frequent occurrences of pre-Columbian artefacts at ADE sites led to their ubiquitous classification as Anthrosols (soils of anthropic origin).
Evidence confirms an anthropic origin of Amazonian Dark Earths
First described over 120 years ago in Brazil, Amazonian Dark Earths (ADEs) are expanses of dark soil that are exceptionally fertile and contain large quantities of archaeological artefacts. The ...

A new hypothesis for the origin of Amazonian Dark Earths
Introduction. Discovered decades ago in central Brazil 1, Amazonian Dark Earths (ADEs) are now regarded as a Pan-Amazonian anthropological phenomenon 2.The exceptional fertility of ADEs, combined with a high concentration of pyrogenic carbon 3, and frequent observations of pre-Columbian artefacts led to their ubiquitous classification as anthropic soils 4, often referred to as Pretic Anthrosols 5.

A new hypothesis for the origin of Amazonian Dark Earths
It is indicated that Amazonian Dark Earth soils predate human settlement and could have alluvial and burning origins, which would transform the understanding of human influence in Amazonia, opening new frontiers for the sustainable use of tropical landscapes going forward.
