Other claims from this paper (13)
- Intervention effect Fertilizer N uptake was similarly unaffected by tillage method.
- Observation Annual fertilizer N use efficiency under NT was 55% at the lowest N rate (56 kg ha −1).
- Observation Annual fertilizer N use efficiency under NT was 54% at the middle N rate (112 kg ha −1).
- Observation Annual fertilizer N use efficiency under NT was 49% at the highest N rate (224 kg ha −1).
- Observation Annual fertilizer N use efficiency under CT was 57% at the lowest N rate (56 kg ha −1).
- Observation Annual fertilizer N use efficiency under CT was 57% at the middle N rate (112 kg ha −1).
- Observation Annual fertilizer N use efficiency under CT was 48% at the highest N rate (224 kg ha −1).
- Observation Maximal silage production under NT was 13.2 Mg ha −1, compared with 12.6 Mg ha −1 under CT.
- Observation Maximal silage production under NT required 24 kg ha −1 more fertilizer N than under CT.
- Intervention effect Soil N uptake decreased by 17% with N additions below or above the optimum rate.
- Intervention effect Soil N uptake was generally unaffected by tillage method.
- Observation Cumulative fertilizer N use efficiencies were similar, suggesting little residual labeled N available to the crop, particularly at near-optimal N rates.
- Recommendation Reasonably high silage levels can be produced without excessive fertilizer N requirements or losses when pastures are converted to NT maize.
