Combinations of phosphorus, nitrogen, and carbon were added to several small lakes in northwestern Ontario, Canada, at rates similar to those in many culturally eutrophied lakes. Phosphate and nitrate caused rapid eutrophication. A similar result was obtained with phosphate, ammonia, and sucrose, but recovery was almost immediate when phosphate additions only were discontinued. When two basins of one lake were fertilized with equal amounts of nitrate and sucrose, and phosphorus was also added… 

Eutrophication of lakes cannot be controlled by reducing nitrogen input: Results of a 37-year whole-ecosystem experiment

Reducing nitrogen inputs increasingly favored nitrogen-fixing cyanobacteria as a response by the phytoplankton community to extreme seasonal nitrogen limitation, and the lake remained highly eutrophic, despite showing indications of extreme nitrogen limitation seasonally.

Phytoplankton Community Responses to Nutrient Addition in Lake 226, Experimental Lakes Area, Northwestern Ontario

Inclusion of phosphorus in fertilizer added to one of two basins of a small lake, between which water exchange was greatly reduced by a vinyl sea-curtain, significantly increased epilimnetic


In the early 1970s, a series of experiments conducted in several small lakes in northwestern Ontario established the critical role phosphorus plays in lake ecology. In one of these experiments, now a

Nutrient dynamics and fertilization effects in two oligotrophic coastal mountain B.C. lakes

Selected nutrient dynamics and the effects of nitrogen and phosphorus fertilization on Twin Lakes, British Columbia, were examined for this research. Twin East Lake and Twin West Lake are small

Nitrogen, phosphorus, and eutrophication in streams

Abstract Flowing waters receive substantial nutrient inputs, including both nitrogen (N) and phosphorus (P), in many parts of the world. Eutrophication science for rivers and streams has

The importance of nitrogen in Pyramid Lake (Nevada, USA), a saline, desert lake

The increase in human development in the downstream portion of the Pyramid Lake drainage basin has resulted in increased nutrient loading to the lake. Since this is a deep, terminal lake, concern

Phosphorus budget and productivity of an experimental lake during the initial three years of cage aquaculture

An experiment was conducted to investigate the effect of rainbow trout (Oncorhynchus mykiss) cage aquaculture on the phosphorus budget and productivity of a small Precambrian Shield lake during the first three years of fish farming.

It is concluded that long-term, whole-ecosystem experiments and case histories of lake recovery provide the only reliable evidence for policies to reduce eutrophication and the case for phosphorus control has been strengthened.



Phosphorus, Nitrogen, and Algae in Lake Washington after Diversion of Sewage

After diversion of sewage effluent from Lake Washington, winter concentrations of phosphate and nitrate decreased at different rates, but nitrate remained at more than 80 percent of the 1963 value and free carbon dioxide and alkalinity remained relatively high.

Atmospheric Carbon Dioxide: Its Role in Maintaining Phytoplankton Standing Crops

The results demonstrate that invasion of atmospheric carbon dioxide may be sufficient to permit eutrophication of any body of water receiving an adequate supply of phosphorus and nitrogen.
