- Observation Nitrogen immobilization was 15% under fall-applied nitrogen alone.
- Intervention effect Less labeled nitrogen leached at harvest with fall nitrogen plus DCD than with fall nitrogen alone.
- Intervention effect Less labeled nitrogen leached at harvest with split-applied nitrogen than with fall nitrogen alone.
- Intervention effect Dicyandiamide did not affect estimates of denitrification.
- Intervention effect Nitrogen timing did not affect estimates of denitrification.
- Intervention effect Second-year wheat grain yield averaged 2.07 Mg ha−1 and was unaffected by the previous nitrogen rate.
