Abstract
The effect of soil redox potential on N2O and N2 emission from soil suspensions was studied under laboratory conditions. Crowley silt loam soil suspensions were equilibrated under controlled (−200, −100, 0, +100, +200, +300, and +400 mV) redox levels, and the amounts of N2 and N2O evolved quantified. At higher redox levels (+300, and +400 mV) nitrification was the dominant soil biological process controlling N chemistry. A small amount of N2O evolved during nitrification. A redox value between +300 and +200 mV was found critical for denitrification to occur. Both N2 and N2O were produced during denitrification. The maximum amount of N2O evolved at a redox value of 0 mV. Dinitrogen emission increased at lower redox levels. The highest N2/N2O evolution ratio was observed at −200 mV and the ratio decreased with increasing redox. A lack of N-balance during denitrification at redox levels of +100, and +200 mV is also reported.
