- Intervention effect Herbicide use above the minimum reduced giant foxtail seed in surface soil.
- Intervention effect Reduced tillage increased surface-soil giant foxtail seed.
- Intervention effect No tillage increased giant foxtail seed over conventional tillage each year.
- Intervention effect Soybean-corn rotation reduced giant foxtail seed versus continuous corn at three sampled soil depths.
- Intervention effect Soybean-wheat-corn rotation reduced giant foxtail seed versus continuous corn at three sampled soil depths.
- Association Giant foxtail stands tended to track soil weed seed counts.
- Intervention effect Crop rotation significantly reduced giant foxtail stands, most in soybean-wheat-corn rotation across tillage systems.
- Mechanism Following wheat under no tillage reduced giant foxtail stands, possibly through straw allelopathy.
