Calibration of plant test for diagnosing zinc deficiency in wheat grown on Zn responsive soils in the Newdegate -Lake Grace district
A range of field experiments were conducted to calibrate a plant test for diagnosing Zn deficiency in wheat under field conditions • The combined results of 6 experiments conducted over 3 seasons indicated a diagnostic critical level of 11-12 mg Zn/kg in youngest fully emerged leaves. Whole shoot Zn concentration varied with growth stage. Using whole shoots an growth stage was required to disgnosis the Zn
