A greenhouse experiment was conducted to evaluate phosphorus availability from natural phosphatic fertilizers (Arad phosphate - Israel, phosphoric bauxite - Senegal, Araxa phosphate - Brazil). Five Brazilian savannah (cerrado) soils were used: Alfisol (PVAe), Oxisol (LVd, LVdf, LVAd), and Quartzipsamment (RQo). Mehlich-1, Mehlich-3 and resin extractants were also used.
