Profitable stubble retention systems for the HRZ locations
Aims

To test and develop farming systems where retained stubble is managed in the HRZ without a reduction in profitability for the grower

Key messages
  • Crops can be established and grown in 6.6 t/ha of retained stubble in the HRZ without compromising establishment
  • Stubble retention in the HRZ requires careful systems based planning and attention to detail
  • Seasonal conditions will strongly influence outcomes of stubble retention through factors such as pest pressure and conserving soil moisture
  • Burning may not be an option in the near future because of unacceptable risks of litigation
