> Researchers have found that the fertile terra preta (black earth) is distributed over large areas in the Amazon forest. It is now widely accepted that these soils are a product of indigenous soil management. The development of this soil enabled agriculture and silviculture to be conducted in the previously hostile environment. Large portions of the Amazon rainforest are therefore probably the result of centuries of human management, rather than naturally occurring as has previously been supposed.

- Jensson 4y agoStill doesn't support the claim that they planted the Amazon forest, just that they lived there and altered it. The Amazon forest mostly doesn't have that soil. > Terra preta soils are found mainly in the Brazilian Amazon, where Sombroek et al.[21] estimate that they cover at least 0.1 to 0.3%, or 6,300 to 18,900 square kilometres (2,400 to 7,300 sq mi) of low forested Amazonia;[1] but others estimate this surface at 10.0% or more (twice the area of Great Britain).[ https://en.wikipedia.org/wiki/Terra_preta https://en.wikipedia.org/wiki/Terra_preta
