      abstract     = {Nitrite (NO−2) and hydroxylamine (NH2OH) are important
                      intermediates of the nitrogen (N) cycle in soils. They play
                      a crucial role in the loss of nitrous oxide (N2O) and nitric
                      oxide (NO) from soil due to their high reactivity. In this
                      study, we collected soil samples from three ecosystems
                      (grassland, arable land, and forest with a riparian zone)
                      and explored the contribution of NO−2 and NH2OH to N2O
                      formation in the different soils after exposure to oxic or
                      anoxic pre-treatment. In addition, the importance of abiotic
                      processes on the N2O formation from the two intermediates
                      was studied by irradiating the soil samples with
                      γ-irradiation. Our results demonstrate that NO−2 addition
                      induced the largest N2O production in the grassland soil,
                      followed by the forest and arable soils. Only $9–39\%$ of
                      the produced N2O after NO−2 addition came from abiotic
                      processes. NH2OH addition increased N2O emissions the most
                      from the arable soil, followed by the grassland and forest
                      soils. The conversion of NH2OH to N2O was mostly
                      $(73–93\%)$ abiotic. Anoxic pre-treatment decreased N2O
                      production from NH2OH remarkably, especially for the
                      grassland soil, while it increased N2O production from
                      NO−2 for most of the soils. Correlation analysis showed
                      that NO−2 effects on N2O production were strongly
                      correlated to NH+4 content in soils with anoxic
                      pre-treatment, while NH2OH effects on N2O production were
                      strongly correlated to soil Mn and C content in soils with
                      oxic pre-treatment. Our results indicate that NH2OH plays an
                      important role for abiotic N2O formation in soils with low C
                      and high Mn content, while the effect of NO−2 was
                      important mainly during biotic N2O production. Anoxic
                      periods prior to N addition may increase the contribution of
                      NO−2, but reduce the contribution of NH2OH, to soil N2O
                      formation.},
