The objective of this work was to evaluate changes in phosphorus fractions in a Humic Cambisol cultivated with vineyards, after 62 years of additional fertilization with poultry litter. 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. |
