Abstract

Study of fertile and dark patches of soils (Indian black earth) near Santarém, Brazil. Soils were found to be anthropogenic in origin, with most produced through soil management practices in agricultural zones and only small porions showing clear evidence of human habitation (i.e., the midden model). Ash and organic matter were deposited to form these patches. Fertility of the soils has persisted long after cultural manipulation has ceased. - (SLD)
