Correction of zinc deficiency in wheat on the Darling Downs, Queensland locations
Aims

To test methods for alleviating zinc deficiency in wheat.

Key messages
  • Zinc sulphate applied as a 1% spray 2-4 weeks after emergence, or drilled with the seed, alleviated the symptoms of zinc deficiency in field trials 
  • Applications five weeks after emergence were not effective.
  • The disorder can also be alleviated by double cropping.
  • Although responses to residual zinc were apparent it is considered more economic to use sprays each year.
