Root Exudates Mediate the Processes of Soil Organic Carbon Input and Efflux

Plants, 2023
Root exudates, as an important form of material input from plants to the soil, regulate the carbon input and efflux of plant rhizosphere soil and play an important role in maintaining the carbon and nutrient balance of the whole ecosystem.
