In a recently published paper (1), the authors report that microbial carbon use efficiency (CUE) is the primary determinant of global soil organic carbon (SOC) storage and that the relative impact of plant carbon inputs on SOC is minor. While soil microbes undoubtedly play an important role in soil organic carbon cycling, we are concerned about the robustness of the approach taken by Tao et al. (1) and highlight potential biases in their analyses that may lead to misleading, model-dependent results.
