Figure 5: Results of the application of the artificial soil regression model for the calculation of NH2OH-to-N2O conversion ratios (RNH2OH-to-N2O) to artificial soil mixtures amended with the different organic materials (n = 22).

The three points for which RNH2OH-to-N2O was determined at pH 3, 4, and 5 without MnO2 addition were excluded from the simulation.
