Table 3. Global warming potential of N2O in the rubber plantation.

Treatments F NF F-NF
N2O flux (kg N ha−1 yr−1) 4.0 2.5 1.5
GWP 1929.1 1217.9 708.8
Ratio to the rubber plantation NEE (%) 5.8 3.7 2.1
Ratio to the tropical rainforest NEE (%) 31.5 19.9 11.6

F indicates fertilized rubber plantation; NF indicates unfertilized rubber plantation; F-NF indicates the difference between fertilized and unfertilized rubber plantation; TRF indicates tropical rainforest.

Rubber plantation and tropical rainforest NEE values were 9.04 t C ha−1 yr−1 49 and 1.67 t C ha−1 yr−1 52, respectively.

The global warming potential of N2O is 310 times that of CO2 over a period of 100 years4,5.
