Dear Dr. Frossard,

you adequatly addressed the few reviewer comments and I agree with the reviewers that the paper is in good shape and will be a valuable contribution to the SOIL journal. However, I have one last comment, which should be addressed, before the final manuscript can be published:

you stated in the introduction, that the contrasting results obtained by different studies may be due to different methods used to determine P and organic P. However, you did not indicate the methods used for elemental determination in the different trials. If they were not the same, the contrasting results for the three study sites may be due to different methods used. As this is a crutial point, the methods should be mentioned.

Moreover, it could be a good idea to re-organise the manuscript according to method description, where all sites are described together with the measurements and a result section, where all results are described.
I am looking forward to see the final manuscript.
Best regards
Cornelia Rumpel
