The uncomfortable truth is that in many paddocks the weeds are winning the battles for space and resources.
Growing crops that out-compete weeds gives a double whammy benefit of more crop and less weeds — generating more profit!
Try some or all of these ideas to give your cropping system the competitive advantage:
- Get the soil pH right and do what you can to improve overall crop nutrition
- Set up your planter to sow crops on the narrowest row configuration possible within the other constraints of crop production
- Sow within the optimal planting window for the crop and your location
- Choose the most competitive crop type (e.g. barley over wheat) and the most competitive variety or hybrid of your chosen crop
- Select crops with early vigorous growth
- Set the crop up for success with optimal weed control prior to planting, using double knock tactics and effective pre-emergent herbicides
- Sow east-west rather than north-south if you can
- Use sowing rates at the upper end of the recommended range for the crop
