Z.  aElemental signatures of an Amazonian Dark Earth as result of its formation process.h[electronic resource]  c2020  aAmazonian Dark Earths (ADEs) are soils studied for archaeological purposes and as a potentially agricultural model for the humid tropic. We investigated the chemical composition of an ADE incomparison to an adjacent Ultisol without anthropic influence for better understanding the origin of ADE fertility and formation process.  aGeochemistry  aTerra Preta de Índio1 aMOTTA, A.
