Prairie Wolf Slough (PWS) is a restored farmed wetland in northeastern Illinois. Past research has shown that concentrations of soluble reactive and total phosphorous in water that discharges from PWS are higher than the phosphorus concentrations in water entering the wetland. This project assessed the contribution of phosphorous from sediment/soil being deposited in the marsh. Sediment/soil samples were collected and measured for Mehlich-3 soil test phosphorous, carbon-nitrogen ratio, and particle size. Sediment traps placed in the marsh measured monthly sedimentation rate. Correlation analysis shows weak associations between soil test phosphorous, and percent silt, sand, and clay. While this does provide a greater understanding of sediment/soil dynamics within the marsh, it does not give reason to such high phosphorous loads in PWS water.
