Fig. 2. Global warming potential (GWP) contribution of N₂O, CH_4, and CO₂ as a function of soil E_H. All eight soils showed the same pattern of (i) N₂O, (ii) CH₄, and (iii) CO₂ dynamics with soil E_H change from high to low. The figure was plotted in a logarithmic scale to cover a wide range of values. Global warming potential contributions below 1 mg CO₂ equivalent kg^–1 h^–1 were considered insignificant and not illustrated in the figure for clarity.
