V. de  aPhosphate sorption as related to mineralogy of a hydrosequence of soils from the Cerrado region (Brazil).h[electronic resource]  c1993  aPhosphate sorption by minerals having surface Fe-OH or Al-OH groups is an important process in highly weathered tropical soils. In this study, P sorption in 12 samples of soils of a typical hydrosequence of the Cerrado region (Brazil) was predicted by means of combining data on: (1) the amount and properties of gibbsite, goethite, hematite and kaolinite, and (2) the P-sorption characteristics of these minerals, according to existing data in the literature. The concentration, crystal morphology and surface area of these four minerals were studied by X-ray diffraction (XRD), thermogravimetry, transmission electron microscopy (TEM) and N2-adsorption.  aBrazil  amineralogy  asoil  asorption  aAdsorção  aCerrado  aFosfato  aMineralogia  aSolo  aBrasil  aPhosphate1 aTORRENT, J.  tGeodermagv.58, p.107-123, 1993.
