Soil organic matter and fertility of anthropogenic dark earths (Terra Preta de Índio) in the Brazilian Amazon basin. The Brazilian Amazon basin in soil organic matter and fertility of anthropogenic dark earths (Terra Preta de Índio). Repository: BDPA Publication year: 2009
Unsaturated hydraulic property measurements of subtropical anthropogenic (purple) soils in China. Many anthropogenic soils, often referred to as red bed or purple soils, are distributed in various areas of southern China. Purple soils typically are highly weathered and often lead to natural and en... ... Repository: BDPA Publication year: 2024
Soil organic matter responses to anthropogenic forest disturbance and land use change in the Eastern Brazilian Amazon. Anthropogenic forest disturbance and land use change (LUC) in the Amazon region is the main source of greenhouse gas emissions to the atmosphere in Brazil, due to the carbon (C) and nitrogen (N) emitt... ... Repository: BDPA Publication year: 2017
Estimating soil carbon in Southern Amazon late holocene anthropogenic landscapes containing archaeological 'Dark Earth' Anthrosols. Amazonian dark earths (ADE) are anthropogenic soils with concentrated carbon and nutrients that formed mainly during the latter half of the Holocene, prior to the arrival of Europeans, but are still f... ...

Extraction and characterisation of humin fraction from Amazonian anthropogenic dark earth soils ("Terra Preta de Indios"). Humin, the humic fraction that is insoluble in water at all pH values, typically comprises more than 50% of soil organic matter (1). Because of the difficulties in isolation, humin compositions and pr... ... Repository: BDPA Publication year: 2008
Diversity of soil fungal communities of cerrado and its closely surrounding agriculture fields. Repository: BDPA Publication year: 2008
Phosphorus forms in cultivated indian black earth (anthrosols) of varying texture in the Brazilian Amazon. Despite the agricultural importance of India Black Earth (IBE) in the Amazon region, there are few studies that report on the relation between soil texture and chemical fertility of IBE. These soils o... ... Repository: BDPA Publication year: 2009
Studies of the compositions of humic acids from Amazonian Dark Earth soils. The compositions of humic acids (HAs) isolated from cultivated and forested "Terra Preta de Índio" or Amazonian Dark Earth soils (anthropogenic soils) were compared with those from adjacent non-anthro... ... Repository: BDPA Publication year: 2007
Chemical functionalisation of actived charcoal - Reproducing the Terra Preta de Índios organic matter model. erras Pretas de Índios are anthropogenic soils found in the Amazon which have high carbon content, high fertility and high resilience. These characteristics are due to the pyrogenic character of their... ... Repository: BDPA Publication year: 2010
Humic Acids of the Amazonian Dark Earth Soils: Terra Preta De Índio. The humic acid fraction (HA) of some Amazonian dark earth soils (Terra Preta de Índio) from Brazil were characterized using ultraviolet-visible (UV-Vis), Fourier transform diffuse reflectance infrared... ...
