Other claims from this paper (12)
- Intervention effect Moldboard plow grain yield averaged 6.5% above chisel plow and no till.
- Intervention effect Nitrapyrin did not increase corn grain yield.
- Intervention effect Nitrapyrin did not increase nitrogen recovery efficiency.
- Intervention effect Nitrapyrin reduced cumulative seasonal N2O emission in one year.
- Intervention effect Tillage affected N2O emissions in two of three years, with MP highest and NT lowest.
- Association N2O emissions were negatively related to NRE under no till.
- Association N2O emissions were negatively related to NRE under strip till.
- Association N2O emissions were negatively related to NUE under strip till.
- Association Under strip till, N2O losses declined 17 g N ha−1 per NRE unit gained.
- Association Under no till, N2O losses declined 13 g N ha−1 per NRE unit gained.
- Association Under strip till, N2O losses declined 63 g N ha−1 per NUE unit gained.
- Recommendation The authors conclude that no till or strip till may reduce N2O emissions by improving NRE or NUE.
