Nitrifier denitrification as a distinct and significant source of nitrous oxide from soil
TL;DR: In this paper, the relative importance of classical and nitrifier denitrification in N2O emitted from soil is a function of the soil moisture content, and likely of other environmental conditions as well.

Nitrifier denitrification can be a source of N2O from soil: a revised approach to the dual-isotope labelling method

TL;DR: In this article, a new isotopic approach was proposed to identify the presence of Nitrifier denitrification in soil, and it was found that in at least five of the soils, Nitrifiers must have contributed to N2O production, and may even have been responsible for all NH4+-derived N 2O in most soils.

Oxygen exchange between nitrogen oxides and H2O can occur during nitrifier pathways
TL;DR: It is concluded that O exchange is likely to be mediated by ammonia oxidizers during NO2− reduction (nitrifier denitrification), and that it could possibly occur duringNO2− oxidation to NO3− by nitrite oxidizers as well.

Inhibition of denitrification and N2O emission by urine-derived benzoic and hippuric acid
TL;DR: In this article, the authors found that Hippuric acid (HA) in cattle urine acts as a natural inhibitor of soil N2O emissions, and they also tested the hypothesis that the inhibition occurs because the HA breakdown product benzoic acid inhibits denitrification rates.

TL;DR: In this paper, the authors identify two mitigation strategies and present experimental results for them: (1) avoiding detrimental soil conditions; and (2) changing urine composition through rationing.
