A review of copper deficiency of wheat in the Inglewood Shire locations
Aims

A review of copper deficiency in the region and procedures for correcting it in wheat.

Key messages
  • Copper deficiency of wheat on the Western Downs is found on grey or grey-brown (brigalow-belah) clays.
  • EDTA-NH4HCO3 extractant provides the most suitable soil test for assessing copper levels in soils.
  • Using this method soils with <0.3 ppm copper would be responsive to copper fertiliser.
  • Yield and profit on responsive soils is maximised by 2 foliar sprays of a 1% copper sulphate solution at 1 kg/ha.
  • No soil samples from of 53 sites sampled in the region between 1983 and 1986 indicated copper deficiency.
