Use of Raman spectroscopy and FT-IR to characterize the biochar in yellow oxiso...
Padilha, Felipe J.; Silva, Marcondes S.; Guimarães, Rodrigo de S.; Cedano, Johnny C.C.; Oliveira, Danielle M.; Damaceno, João B.D.The Amazonian Latosols are acidic soils shows low activity in clay minerals. However, it is also found anthropogenic soils known as Amazonian Dark Earth (EAD) that provides a potential to develop a sustainable system in agriculture. The majority of TPI soils show fragments of black carbon stemming from an anthropic activity. The presence of these fragments endows the improvements in the physic and chemical char...

Chagas, Lillian França Borges; Falcão, Newton P.S.; Padilha, Felipe J.; Oliveira, Danielle M.; Guimarães, Rodrigo de S.; Campos, David Vilas Boas deThe Amazonian Dark Earth (ADE), that is extremely efficient soils in retaining great amount of organic matter of the soil, and for long time, they are still little known with relationship to the effects on the physical fractions of those soils in these adapt tropical region. Therefore, the objective of the present study was to evaluate the space distributions and in depth of the light organic fractions and the ...
