Other claims from this paper (11)
- Intervention effect Hairy vetch no tillage and white clover partial tillage reduced soil loss by up to 90% versus winter fallow conventional tillage.
- Intervention effect The cover crop tillage treatments reduced weeds by 80-90%.
- Intervention effect White clover partial tillage decreased corn yield because of competition for water and nutrients.
- Intervention effect Hairy vetch no tillage increased corn yield against winter fallow conventional tillage regardless of weed control.
- Intervention effect Hairy vetch and rye winter cover reduced soil erosion by up to 95% before corn sowing.
- Intervention effect Hairy vetch no tillage reduced soil erosion during waxy corn growth by up to 98%.
- Intervention effect Incorporating hairy vetch and rye green manure reduced soil erosion by up to 70%.
- Intervention effect Hairy vetch no tillage with standard nitrogen fertilizer raised waxy corn ear yield by 20%.
- Intervention effect Rye green manure lowered waxy corn ear yield without nitrogen fertilizer.
- Intervention effect Hairy vetch no tillage lowered waxy corn ear yield without nitrogen fertilizer.
- Recommendation The authors favor hairy vetch as a winter cover crop to reduce erosion and chemical nitrogen fertilizer together.
