Other claims from this paper (10)
- Intervention effect Drag-shoe banded manure gave yield response similar to mineral fertilizer at equivalent N rates.
- Intervention effect Splash-plate manure yielded 0.5 to 1.0 Mg ha −1 less than fertilizer in summer and spring.
- Intervention effect Splash-plate manure and fertilizer had similar yield response in autumn.
- Intervention effect Drag-shoe manure produced 15 to 20 kg ha −1 greater N uptake than splash-plate manure at high N rates in spring and summer.
- Observation Autumn differences in total N uptake were smaller.
- Intervention effect In summer, drag-shoe application increased apparent manure N recovery by 20 to 30% over splash-plate application.
- Intervention effect Early spring application increased apparent N recovery by 18%.
- Intervention effect Delaying manure application had little yield effect.
- Intervention effect Delayed manure application increased tissue N in some summer and autumn treatments.
- Intervention effect Nitrate concentrations under manure were similar to or below fertilizer treatments.
