Soil samples were collected from two vineyards (V1 and V2) and a forested area adjacent to them. A total of 1,365 and 910 kg ha-1 P were applied to V1 and V2, respectively, throughout the past 62 years. Samples were collected at 0?10, 10?20, 20?30, and 30?40-cm soil depths for the analysis of soil physicochemical properties. The addition of poultry litter to the soil of the vineyards increased the contents of inorganic P (Pi) in all fractions, except in the residual fraction (residual-P), mainly at the 0?10-cm soil depth, in comparison with the forested area. The addition of poultry litter as fertilizer does not affect the organic P (Po) stock in the Humic Cambisol, it only increases the Pi contents of the soil.  aResíduo Orgânico  aVitis Labrusca  aChemical fractionation of P  aFósforo orgânico  aFracionamento químico de P  aGrapevine  aOrganic phosphorus  aOrganic residue  aVideira1 aGATIBONI, L.
