  abstract = {{P}astures cover nearly 50 million hectares in the {C}errado region. {T}he {O}xisols, which cover approximately half this area, are highly weathered soils composed mainly of kaolinite, iron and aluminum oxides. {I}ron and aluminum oxides have a great influence on the retention of phosphorus ({P}) in these soils. {T}he aim of this study was to quantify the total phosphorus levels, as well as {P} availability and retention in {O}xisols under pasture in the {C}errado region and to relate the data with soil mineralogical, textural and chemical characteristics. {T}he relations between the studied parameters were analyzed by principal component analysis and linear correlation analysis. {T}he ion-exchange resin extractable {P} was negatively correlated with mineralogical and texture soil characteristics, and positively with soil organic matter contents. {B}oth the total free and the poorly crystalline oxides were negatively correlated with equilibrium {P} ({P}rem). {G}ibbsite, goethite as well as the total free and poorly crystalline oxides were negatively correlated with {P}rem, indicating their effects on {P} adsorption to {C}errado {O}xisols. {C}onversely, kaolinite was not significantly correlated with {P}rem. {T}he negative correlation between {P}rem and total carbon ({C} total) was due to the linear increase of soil carbon with the clay and silt contents. {T}he iron and aluminum oxides were the characteristics that most influenced {P}rem of {C}errado {O}xisols.},
