- •
Aquaponics could tolerate a wide range of pH from 6.0 to 9.0.
- •
Higher nitrogen utilization efficiency and N2O emission were achieved at pH 6.0.
- •
Denitrification accounted for 75.2–78.5% of N2O emission from aquaponics.
- •
Unfavorable conditions for denitrifiers led to higher N2O emission at pH 6.0.
