Farm Table says:
This research tested the harvest efficiency and efficacy of weed seed capture techniques implemented on 3 heights of wheat and barley in agronomic and economic terms.
The key takeaway messages from this research include:
- Harvesting at 15cm is 20% less efficient than harvesting at 30cm.
- Harvesting at 15cm is 38% less efficient than harvesting at 50cm.
- Harvest efficiency increases at approximately 10% per 10cm of harvest height.
- Additional fuel and hours from 15cm to 30cm cost $13/ha
