Allpaddocks were divided into halves: one received 1.5 t/ha of dolomiticlimestone, 400 kg/ha of a fertilizer formula 0-16-18 and 50 kg/ha ofmicroelements (FLI ); and the other 3.0 t/ha , 800 kg/ha and 50 kg/ ha of the same fertilizers (FL2). Productivity on FL2 pastures was greater than that on FLI pastures, averaging 565 and 395 kg of liveweight gain (LWG)/ha/year, respectively. For all grasses the productivity in both fertilizer treatments decreased linearly from the first to the third, from means of 6î0 and 435 to means of 445 and 325 kg/ha/year, for FL2 and FLI, respectively. Progressive reduction in forage availabilities led to significant reduction of stocking rates over time and consequent productivity. Obviously, balanced nutrition with Ca, P, K, but mainly N, is required to sustain productivity of grass pastures. abeef cattle afertilizer application apastures aAdubação aBrachiaria Brizantha aBrachiaria Decumbens aCerrado aPastagem aProdução aBovino de corte aBrazilian savannas aProduction1 aMACEDO, M.
