Root Exudates And Soil Organic Carbon Encyclopedia Mdpi Rhizodeposition is formed when plant roots release organic and inorganic compounds in the roots to the adjacent soil, which mainly comes from plant detritus, the decomposition and renewal of root cells, and root exudates. gross rhizodeposition carbon accounts for 5–20% of photosynthates [ 15]. root exudation can account for up to 2–11% of. 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. root exudates are notoriously difficult to collect due to their underlying characteristics (e.g., low concentration and fast turnover rate) and the.
Pdf Root Exudates Mediate The Processes Of Soil Organic Carbon Input It seems that these two sentences contradict each other. root exudates contain polysaccharides and ones contribute to the soil aggregates formation and the physical stabilization of organic carbon. l. 116 118. the diagram is poorly drawn. this figure creates a false impression of the replenishment of root exudates from the mao С pool. in. This may be closely related to soil organic matter accumulation and root activity. specifically, surface soil contains more plant residues, leaf litter, and root exudates, the primary sources of soil organic carbon. since the surface soil primarily contains these organic materials, it naturally becomes the main carbon storage area [62,63]. However, the ecological mechanism of soil organic carbon input and efflux mediated by root exudates are rarely analyzed comprehensively. in this review, the main processes and influencing factors of soil organic carbon input and efflux mediated by root exudates are demonstrated. soil minerals and soil microbes play key roles in the processes. The amount and composition of root exudates—low molecular weight carbon compounds released from living plant roots into soil—are expected to shift under global change, and a growing body of.

The root–soil organic carbon paradox. in general plant roots control and influence soil organic carbon (soc) dynamics by providing organic c to the soil primarily in the forms of root litter and rhizodeposition (box 1). this c input results in soc gain, particularly when plant roots promote soc stabilization (box 1). This is supported by earlier evidence where an enhanced release of organic acids within the rhizosphere increased the solubility of poorly available fe pools [34] and where carboxylic acids from root exudates were found to release soil carbon by counteracting mineral protection [7]. however, the effects of other groups of root exudates, e.g.
