When left uncontrolled, populations of annual grass weeds reduce the quality and productivity of sub-clover based pastures and, eventually, out-compete desirable species. Winter cleaning is an effective tactic to reduce annual grass weeds with short seed viability.
If winter cleaning of pastures is carried out correctly, it can lift livestock productivity, while becoming a valuable weed management tool.
At the completion of this module producers will be able to:
- understand how to best utilise winter cleaning of pastures within their production system
- confidently identify the seasonal timing to undertake winter cleaning of pastures
- understand the management considerations that need to be identified prior to winter cleaning pastures.
