For P_UN and P_LF, good correlations (RUN 2 = 0.74**; RLF 2 = 0.90***) were found between the NH3 emissions and TAN content. Thus when the TAN content decreased the NH3 flux also decreased. Good correlations between NH3 flux and TAN content were also found for the C_SF (RSF 2 = 0.93***) and C_UN (RUN 2 = 0.83***).
