Title: Productivity decline of sown tropical grass pastures with age : the problem and possible solutions.
Abstract: The productivity of sown tropical grass pastures declines rapidly as pastures age because of a reduction in available soil nitrogen (N). Initial productivity following establishment is high but pasture quality and growth rates soon decline, leading to lower liveweight gains, increased age of turn-off and/or reduced stocking rates. This loss in production prompts the adoption of management practices which might augment levels of soil available N and hence improve pasture productivity. The likely effectiveness of crop/pasture rotations, fertilizer N, sowing a legume, renovation with or without oversowing a forage legume, and burning are discussed with respect to the maintenance of productivity of newly-sown pasture and the rejuvenation of old, rundown pasture.
