ResumoThe degradation is considered to be the major problem of cultivated pastures in the Cerrado. In Quartzipsament, an experiment was conducted to evaluate several degraded pasture recovering treatments of Brachiaria decumbens, introducing Brachiaria brizantha cv. Marandu. The treatments were: Witness; Liming; Liming + P; Liming + ½(PK); Liming + PK. Liming + PK + Micronutrients; Liming + PK + Micronutrients + Legume. The experimental design was that of randomized blocks with four replications. Three cuts in a 325 days period were done and, in the end, the evaluation of roots production and soil chemical analysis. All renovation systems differed from the witness and some of them differed among themselves in terms of dry mass of aerial portion, with emphasis to the legume treatment. The roots production was significantly greater in three treatments when compared to the witness. Significant increases in the nutrient levels and soil pH were verified, in function of lime and fertilization application
