Comments on ‘Global database and model on dissolved carbon in soil solution’ by Joep Langeveld et al.

Abstract

The authors present a database which they compiled for soil dissolved organic and inorganic carbon alongside a regression model to calculate top and sub soil DOC concentration. I find the paper poorly written and organised and the model is not well constructed, missing major parameters controlling soil DOC. While I appreciate the effort of data collection which could be useful for model evaluation, I do not find model outputs and analyses reliable and do not recommend publishing this manuscript in Biogeosciences in the present format. Major comments: The main problems that I see with this manuscript are as follows: Authors constructed a model based on oversimplified parameters which are not fully representative of the processes that are controlling soil DOC. Additionally, they did not use a proper climate C1 BGD
