- Intervention effect Rice and wheat yield and N uptake were higher with manure combined with mineral fertilizer than with manure alone or mineral fertilizer alone.
- Intervention effect N use efficiency was highest in the manure-alone treatment.
- Observation Soil N input showed a surplus under mineral fertilizer combined with manure.
