Faeces deposition on Amazonian Anthrosols as assessed from 5 beta-stanols
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2011)
In the Amazon Basin, within a landscape of infertile soils, fertile Anthrosols of pre-Columbian origin occur (Amazonian Dark Earths or terra preta de Indio). These soils are characterized by high amounts of charred organic ...
