Biochar effect on the mineralization of soil organic matter.
(Pesquisa Agropecuária Brasileira, v. 47, n. 5, p. 665-671, 2012., 2012)
Organic matter stabilization in two Andisols of contrasting age under temperate rain forest
(2013)
Recent studies with Andisols show that the carbon (C) stabilization capacity evolves with soil age relative to the evolution of the mineral phase. However, it is not clear how soil mineralogical changes during pedogenesis ...
TILLAGE EFFECT ON SOIL ORGANIC MATTER, MYCORRHIZAL HYPHAE AND AGGREGATES IN A MEDITERRANEAN AGROECOSYSTEM
(Sociedad Chilena de la Ciencia del Suelo, 2010)
Mass spectrometry of organic matter influenced by long-term pedogenesis and a short-term reclamation practice in an Oxisol of Brazil
(Agricultural Inst Canada, 2016-03-01)
Little is known about the influence of soil pedogenesis and reclamation practices on the chemical composition of soil organic matter (SOM) in eroded Oxisol. We examined the long-term influence of pedogenesis and 8 years ...
Carbon stock variability and aggregate stability in soils of Amazon, Brazil
(2018-06-01)
Converting natural ecosystems into agro-ecosystems often reduces soil organic carbon content by decreasing carbon input, as well as by increasing erosion losses and organic matter decomposition rate. This study aimed at ...
Efeito de resíduos vegetais de milheto (Pennisetum americanum) e da calagem em algumas propriedades físicas e químicas de um nitossolo vermelho em sistema de semeadura direta
(2006-07-01)
This work studied alterations of physical properties of a distroferric red nitosol due to millet (Pennisetum americanum) covering, with or without liming, in a no-tillage system during the agricultural years of 1999/2000 ...
