Abstract
Background and aims
The 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.
Methods
To examine the effects of SOM on the allocation and dynamics of photosynthetically fixed C, rice plants grown on soils with low (0.5 %), moderate (1.4 %), or high (3.4 %) C content were labeled with 13CO2 and harvested six times in one month.
Results
The highest 13C amount was released from the roots into the soil with high SOC content, whereas the opposite pattern was observed for CO2 losses. Microbial 13C increased with 13C in SOM, when soil C content was low or moderate, but decreased when C content was high. At 30 d after labeling, rice plants allocated 2560 kg C ha−1, 3030, kg C ha−1, and 4580 kg C ha−1 in the soil with low, moderate, and high SOC content, respectively, accounting for a rhizodeposition of approximately 13 %, 15 %, and 30 %, respectively. Most of the root-derived C in low SOM soil was mineralized quickly. In contrast, high and moderate SOM content led to higher incorporation of rhizodeposits into SOM and higher belowground C protection against microbial decomposition.
Conclusions
We concluded that SOM content and consequently, soil fertility play a crucial role in the amount of photosynthates allocated by the plant into the soil and C stabilization. A high SOM level is maintained by the high C input and has longer stability.
