Are organo-mineral complexes and allophane content determinant factors for the carbon level in Chilean volcanic soils?
Garrido-Gutiérrez, Estrella; Matus, Francisco (2012)The existing information on soil carbon (C) stabilisation in allophanic soils is conflicting because active Al3+ and sesquioxides (i.e., the oxides/hydroxides of Al and Fe) as a stabilising agent of soil C are emphasised ...

Black carbon contribution in volcanic soils affected by wildfire or stubble burning
Rivas, Yessica; Matus, Francisco; Rumpel, Cornelia; Knicker, Heike; Garrido-Gutiérrez, Estrella (2012)Forest wildfire and stubble burning practices in agriculture contribute to the formation of black carbon (BC), a continuum of pyrogenic carbon ranging from slightly charred degradable biomass to highly condensed refractory ...

Carbon saturation in the silt and clay particles in soils with contrasting mineralogy
Garrido-Gutiérrez, Estrella; Matus, Francisco; Hidalgo, Claudia; Paz, Fernando; Etchevers, Jorge; Merino, Carolina; Báez, Aurelio (2016)El limo y la arcilla juegan un papel clave en la estabilización del carbono orgánico del suelo (SOC) y son fracciones susceptibles de saturarse de C. En este trabajo se postula que si un reservorio de carbono (C) muestra ...
