Other claims from this paper (11)
- Intervention effect Winter legumes were as effective as fertilizer nitrogen for maximum cotton yield.
- Intervention effect Winter legumes were as effective as fertilizer nitrogen in increasing soil organic carbon.
- Intervention effect Two-year cotton-corn rotation gave little long-term cotton yield advantage beyond soil organic carbon effects.
- Intervention effect Three-year cotton-corn-wheat-soybean rotation gave little long-term cotton yield advantage beyond soil organic carbon effects.
- Observation Cotton yield without winter legumes or nitrogen fertilizer is only slightly above its level 110 years earlier.
- Observation Nonirrigated corn grain yields in rotation with cotton were typically low and appeared nitrogen-limited.
- Intervention effect Crop yields rose as phosphorus and potassium rates increased through the 1950s.
- Observation After the 1997 management and cultivar changes, cotton achieved a record nonirrigated yield of 1910 kg lint per hectare in 2006.
- Observation Corn achieved a record nonirrigated yield of 14.8 Mg grain per hectare in 1999.
- Observation Wheat achieved a record nonirrigated yield of 6.34 Mg per hectare in 2001.
- Observation Soybean achieved a record nonirrigated yield of 4.50 Mg per hectare in 2004.
