The experiment was carried through in protecting environment with the objective to evaluate the effect of the bauxite residue in the macronutrients and dry mass concentrations in the sugar cane. Vases of 10 L had been used that they had received the following rates from bauxite residue: 0, 28, 56, 84, 112 e 140 t ha-1, the used culture was the sugar cane (SP92 4221). The incorporation of the bauxite residue in the soil provided increase in the soil macronutrients concentration’s, being that only for sulphur levels above of 83 t ha-1 had provided reductions of this nutrient. Already for the macronutrients concentration’s determined in the leaf, levels above of 70,5; 125; 101; 56 t ha -1 diminished the nitrogen, phosphorum, potassium and sulphur concentration’s, respectively. However, for calcium and magnesium the use of the residue provided the reduction of foliar concentration. The level of the bauxite residue in which had the biggest production of dry mass was of 64 t ha-1.
