The modification of soil organic matter (SOM) decomposition by plant carbon (C) input (priming effect) represents a critical biogeochemical process that controls C dynamics. However, the patterns and drivers priming effect remain hidden, especially over broad geographic scales under various climate conditions. By combining systematic field laboratory analyses based on multiple analytical statistical approaches, we explore determinants intensity along 2200 km grassland transect Tibetan Plateau. Our results show SOM stability characterized chemical recalcitrance physico-chemical protection explains more variance in than plant, microbial properties. High (up to 137% basal respiration) is associated with complex structures low mineral-organic associations. dependence stabilization mechanisms should be considered Earth System Models accurately predict dynamics changing environments.
