abstract = {Nitrite (NO2−) as an important intermediate of the
biological nitrogen cycle is particularly reactive in acidic
soils and acts as a source of N2O and NOx (NO and NO2).
However, abiotic and biotic pathways of NO2−-driven N2O
and NOx production in forest soil and the role of soil
organic matter (SOM) in these processes are still unclear.
In this study, NO2− was applied to both unsterile and
sterilized soil samples as well as to different SOM
fractions from a Norway spruce forest. Biotic and abiotic
N2O emission was measured with an infrared absorption
analyzer and gas chromatography, while NOx emission was
quantified with a chemiluminescence analyzer. Isotopic
signatures of N2O (δ15Nbulk, δ18O, and 15N-N2O site
preference) were analyzed with an isotope ratio mass
spectrometer. After NO2− addition, a large amount of NOx
was emitted immediately, while N2O emission occurred 15–60
min later and was much lower compared to NOx. Sterilization
of soil decreased N2O emission significantly, but not NOx
emission. The 15N site preference of N2O ranged from 7.98 to
11.58‰ for abiotic and 4.69–7.42‰ for biotic sources.
The fulvic acid fraction contributed the most to abiotic N2O
emission, while the fastest NO and N2O emission occurred
after NO2−application to the humin fraction, followed by
the humic acid fraction. These results are important for the
future understanding of NOx and N2O sources, as well as the
use of isotopic signatures for source-partitioning N2O
emission from soil.},
