Cattail marshes are normally nutrient rich environments, serving to collect phosphorus from incoming streamflow. If cattail uptake of phosphorus (P) for annual growth comes from the water column, annual harvest would improve water quality, but if the P source is sediment, no short term effect would be expected on surface water P concentration. We took monthly sediment cores from a dense cattail stand and from an adjacent open water area throughout over the six month growing season. Using sequential fractionation, bioavailable and recalcitrant P forms (Resin, HCO3, OH, HCl, residual and organic P) were isolated and compared between sites and over the season. Temporal changes were found for some labile fractions with OH P decreasing by 4 to 17 fold between May and August. This was countered by increases in HCO3 P, maintaining an approximate balance throughout the season at both sites. No P form declined in direct response to the ∼5 g/m2 biomass uptake of P.
