Wheat response to zinc locations
Aims

To measure potential responses in wheat.

Key messages

Two years of trials at Forbes on low Zn soils show no indication of wheat response to Zn fertiliser. There is some evidence that Zn deficiency in wheat can be intensified by SU herbicides. However, the critical soil Zn levels needed to justify Zn fertiliser use in wheat grown on lower pH soils treated with SU herbicides is unknown. Fertiliser test strips over a number of years have an important role to play in determining potential Zn responsiveness.
