AbstractMicrobial carbon use efficiency (CUE) affects the fate and storage of carbon in terrestrial ecosystems, but its global importance remains uncertain. Accurately modeling and predicting CUE on a global scale is challenging due to inconsistencies in measurement techniques and the complex interactions of climatic, edaphic, and biological factors across scales.

1 INTRODUCTION The timescales and magnitudes of soil organic carbon (SOC) responses to climate and vegetation change are among the largest uncertainties in the terrestrial C cycle. A substantial fraction of these uncertainties relates to the persistence and cycling of C in soils across scales and depths (Wieder et al., 2018).

arising from: F. Tao et al. Nature https://doi.org/10.1038/s41586-023-06042-3 (2023). Understanding the formation and stabilization mechanisms of soil organic carbon (SOC) is important for managing land carbon (C) and mitigating climate change. Tao et al.1 reported that microbial C use efficiency (CUE) is the primary determinant of global SOC storage and that the relative impact of plant C inputs on SOC is minor.

AbstractSoil organic matter decomposition and its interactions with climate depend on whether the organic matter is associated with soil minerals. However, data limitations have hindered global-scale analyses of mineral-associated and particulate soil organic carbon pools and their benchmarking in Earth system models used to estimate carbon cycle–climate feedbacks.

AbstractThe determinants of fire-driven changes in soil organic carbon (SOC) across broad environmental gradients remains unclear, especially in global drylands. Here we combined datasets and field sampling of fire-manipulation experiments to evaluate where and why fire changes SOC and compared our statistical model to simulations from ecosystem models.
