Other claims from this paper (9)
- Association Cereal rye had the greatest total forage mass in 3 and 4 of 6 years, following corn and soybean respectively.
- Association Cereal rye forage mass was similar to wheat following corn.
- Association Cereal rye forage mass was 860 kg ha −1 greater than wheat following soybean.
- Intervention effect Grazing cover crops increased soil penetrometer resistance compared with nongrazed cover crops.
- Intervention effect Grazed cover crops reduced corn grain yield by 0.4 Mg ha −1.
- Intervention effect Soybean yields following grazed cover crops were similar to nongrazed treatments over 4–6 years.
- Intervention effect Corn yields following cover crops were ranked nonseeded control, Marshall RG, wheat, King RG and cereal rye in that order.
- Intervention effect Soybean yields following cover crops were similar to or less than the nonseeded control.
- Recommendation Grazing cover crops could add value over no cover crop and promote cover crops in the U.S. Midwest.
