Technical Bulletin No. 0929: Nutrient Diffusing Substrate Experiments in the Long-Term Receiving Water Study Rivers and the Androscoggin River, Maine: Summary of Findings

Nutrients, usually nitrogen (N) and phosphorus (P), are often the most important factor regulating periphyton biomass. Understanding nutrient-periphyton communities is invaluable to understanding higher order biotic relationships and developing management strategies related to water quality regulation. Nutrients can be a limiting factor to algal growth.
