| Abstract | Major concerns: Authors have nicely responded to my comment on how hydrolysis process is implemented in the model. I understand that there is lack of data to implement hydrolysis step, independently. reason, authors have merged this step with fermentation process by assuming that hydrolysis is the rate limiting step, supported by observations from rice paddy soil. I was wondering how assumption could be for tundra and organic soil, the relevant systems, for this study. This assumption may contribute significant uncertainty for model predictions, since it regulates storage rate of Carbon. For instance, having microbial uptake as the rate limiting step may lead to substantial discharge and accumulation of oligomers depending on hydrological processes. Overall, carbon turnover rate and GHG emission rates over time. |
