Other claims from this paper (8)
- Method / resource The parsimonious model explained 82% of corn yield response variation.
- Method / resource The model assigned a C humification coefficient of 0.40 to winter hardy cover crop residues.
- Association Yield response per potentially mineralized nitrogen was greater for winter hardy than winterkilled cover crops.
- Method / resource With tillage, winter hardy cover crops had a modeled response coefficient of 0.034.
- Method / resource Without tillage, winter hardy cover crops had a modeled response coefficient of 0.020.
- Method / resource Winterkilled cover crops had a modeled response coefficient of 0.0084.
- Association Preemptive competition for soil nitrate reduced corn yield response.
- Recommendation The authors propose the model data fusion approach for guiding adaptive cover crop and nitrogen fertilizer management.
