Dear authors
please upload a revised version of your manuscript. Because major revisions were suggested by both reviewers, the manuscript will have to go through another round of review.
All the best

Dear authors,
thank you for the revised version of the manuscript. I can see that a lot of effort has been put into the revision, however, language editing would still be beneficial. One concern I share with reviewer #2 is the lack of nitrification measurements, which would be needed for an N2O budget. However, I do think you sufficiently explained that your study's focus was denitrification and not a budget of N2O, and I believe that the nitrogen cycle community will be able to learn from your study.
I have some editorial revisions, which are related to the presentation of the figures, Fig. 3, 4 and 7 are not readable for red-green blind readers, The in-figure legend in Fig. 8 is too small. Please revise.
All the best

Dear authors
thanks for your revised version. I have only one final editorial comment before you manuscript will be ready for publication, which is that in Fig. 7, 8: The '-' in NO3- is missing. Please add this to be consistent with the text.
I would further like to suggest to acknowledge the effort of the two reviewers.
All the best
Carolin Löscher
