Decomposition of soil organic matter (SOM) can be stimulated by fresh
organic matter input, a phenomenon known as the ‘priming effect’. Despite its
global importance, the relationship of the priming effect to mineral weathering and nutrient release remains unclear. Here we show close linkages between mineral weathering in the critical zone and primed decomposition of SOM. Intensified mineral weathering and rock-derived nutrient release are generally coupled with primed SOM decomposit...
