Tactics To Manage Frost Risk In the Eastern Wheatbelt of Western Australia:

  • Crop and variety selection – match to zones according to frost susceptibility
  • Time of sowing – spread flowering and early grain-fill windows
  • Delay wheat sowing on frost-prone areas
  • Blend wheat varieties – long and short season
  • Manipulate crop architecture – narrow row spacing and low seeding rate
  • Agronomic practices to lift soil heat storage – stubble load, deep cultivation, soil inversion, claying
  • Reduce inputs on frost-prone areas
  • Crop grazing – 14 days grazing delays crop flowering by about 7 days
  • Spatial tools and mapping – identifying and assessing damage rapidly
  • Optimising returns from frosted crops – harvest grain, cut and bale for hay, graze, manure, desiccate.
