Other claims from this paper (11)
- Intervention effect Reduced tillage produced higher corn yield than no till, 8.4 versus 6.2 Mg ha−1.
- Intervention effect Reduced tillage had more available soil N than no till.
- Intervention effect Hairy vetch increased corn grain yield.
- Intervention effect Hairy vetch increased soil N.
- Intervention effect Hairy vetch raised NO3-N losses.
- Intervention effect Yield-scaled N2O-N emissions in NT-2019 were twofold higher than RT-2019.
- Intervention effect NT-2019 yield-scaled N2O-N emissions were almost fourfold higher than NT-2021 and RT-2021.
- Association NO3-N leaching correlated positively with soil N availability.
- Association NO3-N leaching correlated positively with corn grain yield.
- Association Soil N2O-N fluxes correlated positively with volumetric water content.
- Recommendation Authors conclude no till is ineffective at decreasing N2O-N fluxes in claypan and fragipan soils.
