Critical level for Zn deficiency of field-grown wheat on Esperance sandplain locations
Aims

Calibration of plant test for diagnosing zinc deficiency in wheat grown on responsive soils of the Esperance sandplain 

Key messages

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 3 experiments conducted over 3 seasons indicated a diagnostic critical level of 12 mg Zn/kg (DW basis) in youngest fully emerged leaves.
