Terra Preta is an anthropogenic carbon-rich soil found throughout the Amazon Basin. It is believed to have supported a large population of native Amazonians, as witnessed and recorded by the Spanish explorer Francisco de Orellana.
It is now known to be a very stable and very fertile soil, which is not typical for tropical climates.
In OTL, the practice of creating it didn't really get beyond the Amazon River as far as I know.
What if, at some point in the last 2000 years, it had spread gradually north, perhaps to the Orinoco area first, then into Columbia, up into Central America and finally to the Yucatan?
Could this have happened?
What effects would it have when it finally reached the cities of the Maya?
Is it possible that (a suitably butterfly infested) Maya would be able to survive relatively intact rather than suffering a post-Classic collapse in the southern lowlands?
