The experiment was conducted on the farm caminho das Pedras in Uberlandia, Triangulo Mineiro. The objetive was evaluate the effect the fertilizer the turkey manure and sources minerals in composition of trace elements in a pasture of Brachiaria decumbens with signs of degradation. Six treatments were used, consisting of control (without fertilization), a mineral dosing, three doses exclusive the turkey manure (1,200; 2,400 and 4,800 kg ha(-1)) and a dosage mixed (2,400 kg ha(-1) of turkey manure + dosage of mineral fertilizer). It was observed that the levels of copper have not been increased in the light of implementation of the turkey manure, and that the absorption of this element is quite different between the rainfall and dry period of the year. The levels of iron and manganese absorption remained similar in the rainfall season and dry the year and the levels of these elements in the fodder are more influenced by the type of soil than by the application of the turkey manure. The largest variation in absorption was observed for the zinc levels in which presented more treatments were applied where turkey manure on the control. This absorption was higher in the rainfall season of the year, indicating that this element should be monitored to have reached levels close to the limits of toxicity to cattle. It follows that the absorption of trace elements was influenced by the application of turkey manure and the periods of cuts of forage.
