Geophysical Research Abstracts, v. 20, EGU2018-18352c2018 aAmazonian Dark Earth (ADE) often shows increased soil fertility compared to surrounding soils, likely linked to its increased concentration of soil organic matter and macronutrients such as phosphorus (P). For P, there is little knowledge whether the higher P availability is a result of increased biological processes (such as organic P mineralization) or physico-chemical processes (such as sorption/desorption), or both. aterra preta aFósforo aAmazonian Dark Earth1 aCHEN, H.1 aLIMA, A.
