Here, we investigate the relationship between CUE and SOC retention and interactions with climate, vegetation, and edaphic properties using a combination of global-scale datasets, an explicit microbial process model, data assimilation, deep learning, and meta-analysis. We find that CUE is at least four times more important in determining SOC storage and its spatial variation worldwide than other assessed factors, such as carbon input, decomposition, or vertical transport. Furthermore, CUE exhibits a positive correlation with SOC content. Our findings point to microbial CUE as a major determinant of global SOC storage. Understanding the microbial processes underlying CUE and their environmental dependence may help predict SOC feedbacks to a changing climate.
