Background and aimsThe cycling of photosynthate carbon (C) released in the rhizosphere has significant implications for C sequestration, microbial activities, and nutrient availability in the soil. It is known that the soil organic matter (SOM) content affects the nutrient status, root growth, rhizodeposition, and microbial composition and activity; however, the effects of SOM and consequently of soil fertility on the belowground allocation and dynamics of photosynthetic C remain unknown.
