A stock grazing trial to determine responses to rates of
superphosphate application and which measures pasture and animal
production is described. Wether hoggets are set-stocked and graze
permanent pastures. Data from two seasons indicate: (1) Linear
responses up to the high rate of superphosphate applied (1000 kg/ha).
(2) Animal measurements may be statistically more sensitive assessments
of fertilizer responses than the pasture measuring technique employed.
(3) High fertilizer applications may minimize adverse effects of
increased grazing pressure in seasonally dry conditions
