Release rates of both ammonium and phosphorus were determined for Barton Broad and a site downstream of Wayford Bridge on the river Ant. Comparable concentrations of interstitial phosphorus and ammonium were measured in sediment cores collected from both sites during the summer. The release rates for the riverine sediment cores were lower than those calculated for the broad. A relationship between the number of Chironomids and tubificids present in the experimental cores and the rates of release determined for Barton Broad was shown to exist. Bioturbation did not appear to have an effect upon nutrient release at the site downstream of Wayfora Bridge.
