Maintaining profitable farming systems with retained stubble locations

To examine two main management options to deal with high stubble loads (≥5t/ha) in 2017, and incorporates many of the main findings from the stubble initiative to date.

Key messages

  • I would like to acknowledge all the collaborating scientists, technicians, staff, farmers and consultants from all of the organisations and groups who have contributed significantly in terms of their time and research capability to each farming systems group to ensure the project in their region is producing the highest quality of work. To keep the list of co-authors to one cricket team (rather than many), only one person from each group was included as authors.
