Timely operations are key to maximising farm profit and sowing is one of the most time-critical operations. This is because of the yield penalty associated with delayed sowing in most regions.
Find out more about this other important factors that can influence wheat yield potential and profit in this publication produded by the GRDC.
Improving pre-emergent herbicide spray coverage in stubble retention systems
How does stubble effect spray coverage?
Will the herbicide wash off the stubble?
Tips to improve your spray coverage
Are there other ways to manipulate your spray setup and improve coverage?
The Hart Field-Site Group thanks the University of Adelaide weeds team and Bill Gordon for assistance with trial development for this project. We also gratefully acknowledge SAGIT for project funding (H114).
Over five seasons Hart and other farming systems groups in the Southern region have investigated whether soil carbon (C) content can be increased through stubble retention +/- additional nutrients to assist the breakdown of stubble.
At the conclusion of five years the project was unable to demonstrate differences in soil C between the stubble and nutrient treatments.
To view the key points and soil C results, see “Soil Organic Matters” Factsheet #4.
This project was funded by Australian Government and GRDC (CRF00002).
