(Elsevier B.V., 2016-01-15)
One of the marks left by prehistoric man in the Amazonas landscape are the dark-colored soil stains, Archeological Dark Earth (ADE), which are rich in organic matter, phosphorus and calcium. The color in this soil is ...
Chemical and physical properties of an anthropogenic dark earth soil from Braganca, Para, Eastern Amazon
(Inst Nacional Pesquisas Amazonia, 2016-12-01)
Although anthropogenic dark earth (ADE) is generally found in non-floodable land, it also occurs on floodplains but, there is no information about the chemical and physical characteristics of ADE in this environment. In ...
