Other claims from this paper (14)
- Intervention effect UDP reduced N2O emissions by 95%.
- Intervention effect DCD reduced N2O emissions by 73%.
- Observation Urea had the highest emission factor at 1.53% of applied N.
- Observation UDP had the lowest emission factor at 0.08%.
- Association Emission peaks were associated with fertilization and appeared within one to two weeks.
- Intervention effect Residual fertilizer treatment effects on ratoon crop N2O emissions were not significant.
- Observation Urea contributed 2% of total annual emissions in the ratoon crop.
- Observation UDP contributed 44% of total annual emissions in the ratoon crop.
- Observation Cumulative NO emissions were not significant in rice or ratoon crops.
- Intervention effect UDP increased grain yield by 16%–19% over urea.
- Intervention effect DCD increased grain yield by 16%–19% over urea.
- Intervention effect UDP increased nitrogen recovery efficiency by 30%–40% over urea.
- Intervention effect DCD increased nitrogen recovery efficiency by 30%–40% over urea.
- Recommendation The authors suggest DCD and UDP to reduce N2O emissions and improve yield and nitrogen use efficiency.
