Nanoclays from an Andisol: Extraction, properties and carbon stabilization

open access: yesGeoderma, 2011
Abstract Soils contain an abundance of nano-size particles. Because of their tendency to aggregate and associate with organic colloids, however, soil nanoparticles are difficult to obtain and characterize. Here we report on a simple and rapid method of extracting mesoporous nanomaterials from the clay fraction of an Andisol with narrow size ...

MINERALOGÍA Y RETENCIÓN DE FOSFATOS EN ANDISOLES

open access: yes, 2009
Los Andisoles son los suelos dominantes en la Meseta Purhépecha, Michoacán, México. Se caracterizan por tener propiedades ándicas, entre ellas, una alta capacidad de retención de fosfatos, lo cual afecta la normal nutrición de las plantas. Las propiedades ándicas se asocian a la naturaleza de la fracción arcillosa amorfa y a los complejos ...
