Soil organic carbon formation efficiency from straw/stover and manure input and its drivers: Estimates from long‐term data in global croplands

between the initial SOC and NCE was resolved, and a positive correlation between soil clay content and NCE was observed. High-resolution mapping of the global NCE derived from manure/straw and insight into NCE dynamics provide a benchmark for diagnosing cropland soil C dynamics under climate change and identifying priority regions and actions for C management.
