Table 3.
Cumulative N2O-N emissions, NH3-N volatilizations and NO3--N leaching through the monitoring campaign, N2O emission factor (EF), and total cumulative N losses. Within columns, means followed by the same letter are not significantly different between treatments according to the Tukey’s HSD test (p = 0.05).
