Temporal dynamics of N2O flux (μg kg−1 hr−1), soil pH, DOC (mg L−1), and -N (mg kg−1) in the control treatment. Different lower case letters indicate a statistically significant difference at α = 0.05.Symbol indicates the application of mineral N fertilizer. Means of 3 replicates with standard error.
