This fact is linked to the high capacity of these soils in retaining P in the solid phase, in the form of low solubility compounds. However, the cultivation systems and the management of phosphate fertilization can influence the potential of supplying of nutrient by the soil and its uptake by crops (Sousa & Lobato, 2003). In this work, it was aimed to quantify inorganic and organic fractions of phosphorus in soil of the cerrado region, as a function of different methods application of some phosphorus in soil of the cerrado region, as a function of different methods application of some phosphorus sources with different solubilities, after three successive corn cultivations.  aCerrado  aFertilidade do Solo  aFósforo  aSolo1 aFURTINI NETO, A.
