Phosphorus is among the macronutrients the least absorbed by plants. Nevertheless, the amount of P-containing fertilizers applied to humid tropical and subtropical soils in relatively high. The reason is the strong interaction between of P and Fe and Al oxides, which are abundant in these soils. The study of these interactions is fundamental to know more about the relations between phosphorus adsorption and soil constituents. The objective of this study was to evaluate how the minerals in the clay fraction, […]
