Lessons from the Terra Preta de Índios of the Amazon region for the utilisation of charcoal for soil amendment
(Sociedade Brasileira de Química, 2009)
The potential of charcoal and of partially combusted organic waste to mimic the soil organic matter of the Terras Pretas de Índios (Amazonian Dark Earths) from the Amazon Region is discussed. These materials serve as soil ...

NUTRIENT AND ORGANIC CARBON RELEASE IN SOILS CONTAINING WASHED AND NOT WASHED HYDROCHAR COMPARED TO ANTHROPOGENIC SOILS
(Soc Brasileira Quimica, 2019-03-01)
Hydrochar washed (1.0, 2.5, 5.0 and 10.0 %) and not washed (10.0%) produced by hydrothermal carbonization using vinasse and sugarcane bagasse was applied in sand, ultisol and oxisol columns, and the release of NO3-, ...
Morphological analysis of soil particles at multiple length-scale reveals nutrient stocks of Amazonian Anthrosols
(2018-02-01)
We have imaged the particles of Brazilian soils at multiple length scales, from a few microns to millimeters, and soil particle size distributions were calculated with unmatched precision. The analysis included the Amazonian ...
