- •
Polymer coating urea halved the GWP and improved crop yields.
- •
Polymer-coated urea reduced CH4 emission significantly.
- •
Nitrification inhibitors reduced N2O emission significantly.
- •
N2O emissions accounted for 27–37% of total GWP over whole rotation.
- •
N2O emissions and CH4 consumptions were notable during fallow period.
