Carbon and nutrient mobilization across inundation gradients in an emerging freshwater delta

Key Points

• This study aims to understand how soil age and inundation patterns influence carbon and nutrient dynamics in freshwater deltas.
• Examined gradients of soil age and inundation frequency in emerging freshwater deltas.
• Analyzed biogeochemical processes related to carbon and nutrient mobilization.
• Measured soil chemical properties to assess their impact on carbon dynamics.
• Inundation frequency significantly influences carbon mobilization rates, with older soils showing higher carbon release rates.
• Nutrient dynamics are closely linked to soil age, affecting overall biogeochemical processes in the delta.
• Results indicate that different inundation patterns lead to distinct nutrient cycling outcomes in freshwater ecosystems.
