| description | <abstract language="eng">The chemical role of iron-bearing compounds on the dynamics of phosphorus in selected Brazilian latosols was investigated. The iron oxides were characterized in an attempt to assess their main chemical-mineralogical properties influencing the ion sorption mechanisms in those pedosystems. It was found that increasing total iron contents tend to increase the phosphorus adsorption capacity in the selected soils. 110 K-Mössbauer data reveal that the dominant iron oxides are hematite and goethite. Particularly for the yellower soil samples some prominent doublets, more certainly due to superparamagnetic relaxation, may be assigned to corresponding fractions of relatively small-sized particles. |
