An experiment was conducted in a greenhouse of the Centro de Ciências Agrárias, Universidade Federal de Alagoas - Rio Largo/AL, aiming to evaluate the effect of different doses of P recommended by the maximum adsortion capacity of phosphorus - CMAP (%), on content of P and the production of mass of dry matter in corn. The soils were classified as cohesive Yellow Latosol, Gray Argisol, Fluvic Neosol, Quartzarenic Neosol, ortic Chromic Luvisol and palic Chromic Luvisol. Soil samples were taken for physical, chemical and mineralogical analyses. The experiment was arranged in a factorial design (6 x 4) corresponding to the 6 soils and the 4 doses of P (0, 10, 20 and 30% of the CMAP), in a randomized block design. The determination of the remenecent P was made in a equilibrium solution. The CMAP was determined through the remenecent phosphorus. As experimental units, plastic pots were used with the capacity of 10 dm³ containing 7 dm³ of soil. The mass of dry matter of the aerial part of the plant presented better result in the palic Chromic Luvisol, with the dose of 10% of the CMAP and the Fluvic Neosol provided the highest content of phosphorus in the plant with the dose of 30% of the CMAP.
