Modeling phosphate adsorption on a Brazilian Modeling phosphate adsorption on a Brazilian Oxisol Oxisol

The competitive phosphate-carbonate desorption process in the samples was interpreted with the CDMUSIC model 1 . In this modeling calculations, the properties of the individual minerals (goethite) were considered through an additive approach. In this approach, both reactive oxide surface area and reversibly bound phosphate were calculated with the model and data were included in the study of the adsorption properties of soil.
