Question

Quizplus · Accepted Answer

The whole lake fertilization experiments conducted by David Schindler and colleagues in Ontario, Canada, did not lead to the conclusion that nitrogen and carbon were not required for algal growth. Instead, the experiments showed that phosphorus was the major cause of cyanobacteria and phytoplankton blooms and led to recommendations to remove phosphates from water during sewage treatment. The experiments also involved controlled experiments in natural ecosystems and helped trigger a campaign to ban phosphates in detergents.
