Novel estimation of the humification degree of soil organic matter by laser-induced breakdown spectroscopy
(Elsevier B.V., 2014-09-01)
Soil organic matter (SOM) constitutes an important reservoir of terrestrial carbon and can be considered an alternative for atmospheric carbon storage, contributing to global warming mitigation. Soil management can favor ...
Humic fractions of forest, pasture and maize crop soils resulting from microbial activity
(Sociedade Brasileira de Microbiologia, 2014-09-01)
Humic substances result from the degradation of biopolymers of organic residues in the soil due to microbial activity. The objective of this study was to evaluate the influence of three different ecosystems: forest, pasture ...
Application of chemometric methods in the evaluation of chemical and spectroscopic data on organic matter from Oxisols in sewage sludge applications
(Elsevier B.V., 2010-02-15)
Chemometric methods can contribute to soil research by permitting the extraction of more information from the data. The aim of this work was to use Principal Component Analysis to evaluate data obtained through chemical ...
Multimethod study of the degree of humification of humic substances extracted from different tropical soil profiles in Brazil's Amazonian region
(Elsevier B.V., 2005-07-01)
This work consisted of determining the degree of humification of humic substances (HS) extracted from six different Amazonian soils collected from flooded and unflooded regions at different depths (0-10, 10-20, 20-40, and ...
