Other claims from this paper (15)
- Intervention effect Legume cover crop species increased subsequent crop yield significantly more than grass, by 14%.
- Intervention effect Legume cover crop species increased subsequent crop yield significantly more than nonlegume broadleaves, by 7%.
- Intervention effect Legume cover crop species increased subsequent crop yield significantly more than mixtures, by 2%.
- Intervention effect Incorporating cover crop residue into soil increased crop yield by about 15% compared with leaving the residue on the soil surface.
- Intervention effect Grass cover crops enhanced crop yield by 14% relative to no cover crop in non-organic vegetable systems.
- Intervention effect Legume cover crops enhanced crop yield by 19% relative to no cover crop in non-organic vegetable systems.
- Intervention effect Legume cover crops increased crop yield by 18% relative to no cover crop in coarse textured soil.
- Intervention effect Legume cover crops increased crop yield by 4% relative to no cover crop in medium textured soil.
- Intervention effect Legume cover crops increased crop yield by 11% relative to no cover crop under high precipitation.
- Intervention effect Cover crops decreased silage corn yield.
- Intervention effect Grain corn yield did not decrease with cover crops.
- Intervention effect Soybean yield did not decrease with cover crops.
- Intervention effect Winter wheat yield did not decrease with cover crops.
- Intervention effect Cover crops in no-tillage and plow tillage systems increased crop yield compared with the no-CC control.
- Recommendation Crop yield response to cover crops might become more robust when pedo-climatic and agronomic factors are considered.
