Soil organic carbon (SOC) plays a critical role in regulating the global (C) cycle, with forest soils serving as significant C sinks. aggregate stability and distribution of SOC different fractions would be affected by types. In this study, we investigate dynamics within soil across three main types Huron Mountains, Michigan, USA: white birch–eastern hemlock mixed forest, eastern-hemlock-dominated sugar maple forest. We hypothesize that variations species composition depth influence storage through mechanisms such root interactions, microbial activity, structure development. samples were collected from intervals (0–20 cm, 20–40 40–60 cm) analyzed for size content. The results showed stocks differ significantly types, exhibiting highest proportion large aggregates (>1.0 mm), which contribute to more stable structures. This type also had total mass mean weight diameter, indicating enhanced stability. contrast, displayed greater smaller lower macroaggregate-to-microaggregate ratio, suggesting fewer soils. closely linked size, macroaggregates containing SOC. These differences can attributed several underlying mechanisms, including plant physical properties soil. Forests diverse compositions, tend support complex systems communities, leading improved aggregation storage. Additionally, management practices selective thinning mixed-species planting these processes enhancing structure, increasing biomass, promoting health. interactions play crucial sequestration improving Our findings emphasized importance influencing stability, offering insights into study provided reference deeper understanding potential ecosystems supports development sustainable strategies mitigate climate change.
