Managing Frost Risk

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.
