      abstract     = {Liming of acidic soils has been suggested as a strategy to
                      enhance N2O reduction to N2 during heterotrophic
                      denitrification, and mitigate N2O emission from N fertilised
                      soils. However, the mechanisms involved and possible
                      interactions of key soil parameters (NO3− and O2) still
                      need to be clarified. To explore to what extent soil pH
                      controls N2O emissions and the associated N2O/(N2O + N2)
                      product ratio in an acidic sandy soil, we set-up three
                      sequential incubation experiments using an unlimed control
                      (pH 4.1) and a limed soil (pH 6.9) collected from a 50-year
                      liming experiment. Interactions between different NO3−
                      concentrations, N forms (ammonium- and nitrate) and oxygen
                      levels (oxic and anoxic) on the liming effect of N2O
                      emission and reduction were tested in these two sandy soils
                      via direct N2 and N2O measurements.Our results showed
                      50-year liming caused a significant increase in
                      denitrification and soil respiration rate of the acidic
                      sandy soil. High concentrations of NO3− in soil
                      (>10 mM N in soil solution, equivalent to 44.9 mg N
                      kg−1 soil) almost completely inhibited N2O reduction to N2
                      $(>90\%)$ regardless of the soil pH value. With decreasing
                      NO3− application rate, N2O reduction rate increased in
                      both soils with the effect being more pronounced in the
                      limed soil. Complete N2O reduction to N2 in the low pH sandy
                      soil was also observed when soil NO3− concentration
                      decreased below 0.2 mM NO3−. Furthermore, liming
                      evidently increased both N2O emissions and the N2O/(N2+N2O)
                      product ratio under oxic conditions when supplied with
                      ammonium-based fertiliser, possibly due to the coupled
                      impact of stimulated nitrification and
                      denitrification.Overall, our data suggest that long-term
                      liming has the potential to both increase and decrease N2O
                      emissions, depending on the soil NO3− level, with high
                      soil NO3− levels overriding the assumed direct pH effect
                      on N2O/(N2+N2O) product ratio.},
