- Observation Soil total N declined exponentially under all cereal management treatments.
- Observation Apparent fertilizer N recovery was 46% at 90 kg N ha−1.
- Observation Apparent fertilizer N recovery was 59% at 30 kg N ha−1.
- Observation Soil profile mineral N ranged from 68 to 496 kg N ha−1.
- Intervention effect Nitrogen-use efficiency was similar under conventional and no tillage.
- Intervention effect Residue retention had higher N-use efficiency than residue burning.
- Intervention effect Low N application had higher N-use efficiency than high application.
