Description: | A grazing trial was conducted, to study the effects of fertilization on the maintenance of the productivity of four tropical grasses. The paddocks were subsoiled, and dived into halves: received one (LFI) received 400kg/ha of the same fertilizer formula 0-20-20. and the other (LF2) 800 kg/ha of the same fertilizars, in january 1995. Annually, 50 kg/ha of the N was applied. The productivity on LP2 pastures was greater than that on FL.1 pastures, averaging 520 and 410 kg of liveweight gain/ha/year. A double strategy should be followed to sustain animal production in the savanna: maintain soil P over a critical value of 3,0 mg P (Mechilich-1)/dm, and annual N appliocation. |
