Dear Dr. Mondini,
thank you for your response to the two review reports.
Your response to reviewer #1:
In your revised manuscript, please make sure that you explicitly describe the methods on how the partitioning the organic amendment entering DPM, RPM and HUM was tested in the laboratory and in the model. Please explicitly describe the effect on RMSE and why you decided to add more pools instead. Please discuss the effect of entering more pools on lowering RMSE and on increasing the number of required parameters. Your suggested modifications in the introduction are a good start, but the point reviewer 1 addresses here, needs to be considered in the other sections of the manuscript as well.
Your response to reviewer #2:
1. Please add the AIC results that you have obtained from the two model structures in the results and discussion section.
2. your response regarding the proposed model modification to discuss the RothC mineralization dynamics. The response to this reviewer comment should be included in the discussion section as well.
Please provide a modified manuscript that addresses all above-listed points.
Many thanks and best wishes,
Kirsten Thonicke.
