Wetlands are being constructed for ecological functions including wastewater treatment, flood abatement, habitat, and nutrient and pollutant removal within a landscape. Nutrients are stored within the sediment and vegetation of newly constructed wetlands, potentially removing excess nitrogen (N) and phosphorus (P) running off the landscape into freshwater bodies. Topography in constructed wetlands leads to variation in water level and soil moisture, a common control on wetland biogeochemical cycling. Under inundated and reducing conditions, denitrification can drive N removal from sediment, however there is potential for P release through the dissolution of iron oxides. Despite the differences between wetlands and their designs, water level remains a common control on the biogeochemical cycling that occurs, which makes understanding how man-made systems like constructed wetlands experience nutrient cycling between topographic features under varying hydrologic conditions crucial. The main questions for this study are: 1) Does nutrient flux in constructed wetland pools increase under a gradient of inundation status? 2) Will soils exhibiting a lower inundation status experience a release of ammonia and dissolved reactive phosphorus when rapidly inundated? To explore how future fluctuating hydrologic conditions may affect wetland nutrient cycling, we conducted an intact sediment core incubation at an H2Ohio wetland in northeast Ohio. The Trumbull Creek wetland is a former agricultural field, recently restored with diverse topographic features that experience variable levels of inundation throughout the year. Across inundation regimes, sediment and surface water exchange rates of NO₃⁻ ranged from -2-3 mg/m²/day, NH₄⁺ from -500-1,000 mg/m²/day and dissolved reactive phosphorus (DRP) from -4-2 mg/m²/day. We observed that inorganic nutrient flux between sediments and surface waters was highly variable across inundation regimes and throughout time. In some instances, sediments switched from being a sink of DRP to a source during the second and third day of the incubation period. As climate change continues to affect inundation regimes in regions across the globe, exploring how more frequent and intense dry/rewetting periods change the duration of overlying surface water and nutrient cycling in wetlands will become increasingly important.
