Abstract Priming effects of soil organic matter decomposition are critical to determine carbon budget and turnover in soil. Yet, the overall direction intensity priming remains under debate. A second‐order meta‐analysis was performed with 9296‐paired observations from 363 primary studies general depending on compound type, nutrient availability, ecosystem type. We found that fresh inputs induced positive (+37%) 97% paired observations. Labile compounds larger (+73%) than complex (+33%). Nutrients (e.g., N, P) added reduced compared without N P, reflecting “nutrient mining matter” as one main mechanisms effects. Notably, tundra, lakebeds, wetlands, volcanic soils showed much (+125%) forests, croplands, grasslands (+24…+32%). Our findings highlight predominant most at a global scale. Optimizing strategies incorporate nutrients is urgently needed offset priming‐induced accelerated possible losses.
