The take home messages from this GRDC funded research are below. Please access the full paper via the link below for methodology, references, acknowledgements and discussion.
Take home messages from the paper include:
- Don’t let stubble compromise the BIG THINGS – weeds, disease, pests and timeliness.
- Be flexible and pro-actively manage stubble for your seeding system.
- Harvest high = reduced costs and is quicker.
- Cereal stubble should be thought of as a source of carbon (C), not nitrogen (N) (<6% crop N needs obtained from straw).
- Post-harvest management: if necessary reduce stubble load by mulching, incorporation with nutrients, baling or grazing.
- If stubbles are too thick to sow through, consider strategic late burn, especially before the second wheat crop or if sowing canola into large stubbles.
- Managing N at sowing: deep band N and add 5kgN/t cereal stubble.
- Diversify your crop sequence and add legumes to rotation.
- Incorporate AHRI’s ‘Big 6’ for weeds (disc or tine)
