    The plastering along with a liming process has been of great importance without preparation ofsoil applied to different cultures, making a correction of the high aluminum thoughts, and pHalteration respectively, besides calcium, magnesium and sulfur to the cultures, thus contributingto the environment soil, and as a consequence favoring root development, thus enabling anavailability of resources for plants. The objective of this work was to evaluate the parameters,the technological quality and the soil and the productivity of the sugarcane, where agriculturalgypsum and limestone doses were applied to soil with high aluminum content. The study wascarried out at Fazendo Porto in the municipality of Andira / PR in Oxisol Dystroferric, and wasused in the variety of sugarcane RB 85-5453. The study was evaluated in 4 treatments and 4replicates, with T1 = (Witness: 0 Mg ha-1 limestone + 0 Mg ha-1 gypsum), T2 = (0 Mg ha-1limestone + 2 Mg ha-1 of gypsum), T3 = (0 Mg ha-1 limestone + 4 Mg ha-1 gypsum), T4 = (0Mg ha -1 limestone + 8 Mg ha-1 gypsum), T5 = (3 Mg ha -1 of limestone + 0 Mg ha-1 ofgypsum), T6 = (6 Mg ha-1 limestone + 0 Mg ha-1 gypsum), T7 = (3 Mg ha-1 limestone + 4 Mgha-1 of gypsum). As parcels were constituted by 8 lines of cane with spacing of 1.5 m by 10.0m in length, forming an area of 120 square meters. A useful area consisted of 4 cane lines,discounting 2 meters between parcels, totaling a useful area of 60 square meters. There are twogroups: average number of profiles, colometer weight, stem height, productivity andtechnological quality: Brix (%), Pol (%), ATR, AR, Purity (%), Fibers , pH, saturation of bases(V%), saturation by aluminum (m%), contents of K, S. The results allowed to conclude that theliming and gassing did not alter the development of the plants along the experimental cycle, aswell as the Pare of technological quality and its production under the experimental conditions.As for the chemical quality of the soil, there was an increase in the pH, V%, and S content, withconsequent reduction of aluminum saturation.
