Other claims from this paper (7)
- Intervention effect Under zero N fertilizer, retained straw increased rice grain yield in year three.
- Intervention effect Straw retention increased rice N uptake by 19 kg N ha −1 where no N fertilizer was applied.
- Intervention effect Straw retention increased rice N uptake by 12 kg N ha −1 at recommended rate of N fertilizer application.
- Intervention effect Winter flooding further increased rice N uptake with straw retention.
- Mechanism Additional soil N from straw increased rice N uptake without increased grain yield.
- Mechanism Additional soil N from straw decreased rice N use efficiency.
- Recommendation The authors call for re-evaluating N fertilizer application rates.
