Other claims from this paper (7)
- Observation Nitrate leaching from silage maize without cover crops differed considerably between trials, from 39 to 260 kg N per hectare.
- Intervention effect Undersown cover crops generally had a very limited effect on nitrate leaching from maize.
- Intervention effect Undersown chicory significantly reduced nitrate leaching from maize by 75 kg per hectare, in only one trial.
- Association Across all trials and treatments, nitrate leaching increased significantly and non-linearly with N concentration in harvested maize biomass.
- Association As N concentration in harvested maize biomass rose, maize dry matter yield decreased.
- Observation Under wet, temperate conditions there is a risk of nitrate leaching from maize during and after the growing season that undersown cover crops could not effectively prevent.
- Recommendation N supply to maize should be optimized to reduce nitrate leaching while keeping appropriate biomass N concentration and yields.
