Uptake of cobalt (Co) and copper (Cu) by ryegrass- white clover based pasture was measured from December 1999 to March 2000 at Woodlands Research Station in Southland. Treatments were control, cobalt sulphate (CoSO4) at 120 and 240 g/ha initially and 60 g/ha monthly, and copper sulphate (CuSO4) at 5 and 10 kg/ha initially and 1.25 kg/ha monthly, applied in either solid or liquid forms. At 120 g CoSO4/ha applied as solid and liquid, pasture Co content was significantly (P
