Stubble management to reduce the impact of frost to crops in the Albany and Kwinana West Zone of WA locations
Aims

To quantify the impact of stubble on the severity and duration of frost through canopy temperature and grain yield.

Key messages

Preliminary results have shown that the removal of stubble can reduce frost severity and duration. However, this does not advocate the complete removal of all stubble on farming properties. The removal of stubble may be beneficial in low lying frost prone areas of paddocks.
