Dear Authors

thank you for your detailed responses to reviews. Overall the reviewers rated your paper highly, and I agree it is a very useful product with novel science.

I just have a couple of minor points related to reviewer 1 that I would like clarification upon:

Rev 1.
Labile C: I remain confused by your added text on this matter. Is allocation to labile capped at 40% (i.e. a flux cap), or is the labile pool total capped at 40% of another pool's value (i.e. a stock cap)? Perhaps an equation would clarify. What happens once the cap is reached in terms of using the C that would have been allocated to labile? Is GPP down regulated, or is there excess respiration?

For labile N it is not clear how this pool is constrained by leave and roots N sources. Do you mean sinks?

best wishes
