Zinc is essential for Wimmera and Mallee crops and pasture locations
Aims

To review of importance of zinc in the Victorian Mallee and Wimmera.

Key messages
  • Yields may be limited by zinc even where deficiency symptoms are not apparent.
  • Responses to zinc are common on clays in the Wimmera and sands in the Mallee.
  • Phosphorus is required to make zinc fertiliser effective.
  • Grain protein is not increased by zinc application.
  • Applications of zinc are recommended every second or third crop as zinc has some residual value in the soil.
  • Zinc is typically applied in a mixture with phosphorus fertiliser.
  • 2 - 2.5 kg /ha zinc should be sufficient for 4-6 years.
