Characteristics of light fraction organic matter in surface soil of different altitude forests in Wuyi Mountain

A study on Mount Wuyi reveals that mixed coniferous and broad-leaved forests (BCF) exhibit higher light fraction organic matter content and carbon storage compared to evergreen broad-leaved forests (EBF) and coniferous forests (CF). This finding suggests BCF plays a significant role in soil organic carbon dynamics. The research used density fractionation to analyze surface soil samples from different forest types across elevations, showing that fine root biomass is a crucial source of light fraction organic matter. This insight is vital for understanding soil carbon cycling under future climate and vegetation changes.
