A study in the Brazilian state of Amazonas demonstrated that small amounts of Amazonian black soil (ADE) – an anthropogenic soil created by ancient Amazonian populations – can increase the height and diameter of the pink trumpet tree (Handroanthus avellanedae) by up to 55% and 88%, respectively. This tree is also present in the Atlantic Forest. The research is published in the journal BMC Ecology and Evolution.
