Influence of organic and mineral fertilisation on organic matter fractions of a Brazilian Acrisol under maize/common bean intercrop
(Australian Journal of Soil Research, 2019)
Are active organic matter fractions suitable indices of management effects on soil carbon? A meta-analysis of data from the Pampas
(Taylor & Francis, 2016-03)
Active fractions of organic matter have been proposed as early indices of changes in soil organic carbon (organic-C) induced by management. We performed a meta-analysis of published results from 31 field experiments conducted ...
Migration of dissolved organic carbon in biochars and biochar-mineral complexes.
(Pesquisa Agropecuária Brasileira, Brasília, DF, v.47, n.5, p.677-686, maio 2012., 2012)
Carbon isotope fractionation during calcium carbonate precipitation induced by urease-catalysed hydrolysis of urea
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
Stable carbon isotopic fractionation during calcium carbonate precipitation induced by urease-catalysed hydrolysis of urea was experimentally investigated in artificial water at a constant temperature of 30 degrees C. ...
Chemical and oxidizable fractions of soil organic matter under different management systems in an Oxisol
(Empresa Brasil Pesq Agropec, 2016-09-01)
The objective of this work was to evaluate soil quality from soil organic matter (SOM) chemical and oxidizable fractions in areas with different management systems. The study was carried out in the municipality of Guaira, ...
Soil Carbon Turnover Measurement by Physical Fractionation at a Forest-to-Pasture Chronosequence in the Brazilian Amazon
(SPRINGER, 2009)
The effect of conversion from forest-to-pasture upon soil carbon stocks has been intensively discussed, but few studies focus on how this land-use change affects carbon (C) distribution across soil fractions in the Amazon ...
Determination of the volume fraction of retained austenite in a 300m steel by heat tinting technique
(2007-12-01)
Applying the Heat Tinting Technique the microestrutural characterization of a 300M steel (medium carbon steel) was accomplished. The steel was austenitized for 20 min to 900°C, followed by holding at 400°C (in the bainitic ...

Spectral responses to labile organic carbon fractions as useful soil quality indicators across a climatic gradient
(Elsevier, 2020)
Light fraction (LF) and permanganate-oxidizable C (PDXC) demonstrate high reliability as indicators for monitoring soil functioning in response to changes in soil organic carbon (SOC). However, mechanisms affecting the ...
