Studies were performed to determine the effects of nutrient addition to an Alaskan freshwater wetland. Nitrogen (as urea), phosphorus (as a super triple phosphate fertilizer), and secondary sewage were added to a freshwater Sphagnum wetland. Changes in the end-of-season standing biomass of the herb and shrub community were estimated. The nutrient-depth distribution in the Sphagnum was also recorded. Plots receiving the urea and phosphate fertilizer showed increased biomass when compared to controls. No changes in community structure were observed. Added nutrients appeared to be retained in the surface of the Sphagnum. No stimulatory effect of sewage was detected, probably the result of low application rates.
