Annotation	The objective of this study was to investigate how changes in soil pH affect the N₂O and N₂ emissions, denitrification activity, and size of a denitrifier community. We established a field experiment, situated in a grassland area, which consisted of three treatments which were repeatedly amended with a KOH solution (alkaline soil), an H₂SO₄ solution (acidic soil), or water (natural pH soil) over 10 months. At the site, we determined field N₂O and N₂ emissions using the ¹⁵N gas flux method and collected soil samples for the measurement of potential denitrification activity and quantification of the size of the denitrifying community by quantitative PCR of the narG, napA, nirS, nirK, nosZ denitrification genes. Overall, our results indicate that soil pH is of importance in determining the nature of denitrification end products.
