What are teh drivers of fine root decomposition?
Fine root decomposition is influenced by various drivers. Studies have shown that the carbon content of fine roots, soil enzymatic activities, and the functional groups of soil fungi play crucial roles in fine root decomposition. Additionally, traits such as mycorrhizal association, woodiness, nitrogen and phosphorus concentrations, lignin concentration, temperature, and moisture levels have been identified as important factors affecting fine root decomposition at both global and local scales. Furthermore, initial concentrations of aluminum, manganese, phosphorus, calcium, non-structural carbohydrates, cellulose, lignin, and carbon:nitrogen ratios have been highlighted as predictors for fine root decomposition among different tree species. These findings collectively emphasize the complex interplay of chemical, biological, and environmental factors in driving the decomposition of fine roots in terrestrial ecosystems.
