Dear Authors,

thank you for the response to the reviewers and incorporation of their suggestions.
I read the Abstract and looked on the Tables and Figures,
and to regret - the Conclusions and the main outcomes of the paper are not clear. So, despite a lot of work was done, the outcome / conclusions are not clear, or mainly described by general words, that can be written also without to do such a lot of work.
So, I request you to put in the abstract clear and quantitative conclusions to: 1) climate effects, 2) grazing effects and this on 3) plant biomass and 4) SOC. Your conclusions should be quantitative and all general words should be removed. Also the relevance of the conclusions should be presented.
Please add / improve this and your paper will get much more attraction of the readers.

Sincerely yours,
Yakov Kuzyakov
