Nitrogen and phosphorus are the primary macronutrients that often limit algal and plant growth in natural, low-nutrient or “oligotrophic” aquatic ecosystems.  However, in nutrient over-enriched or “eutrophic” aquatic ecosystems, excess nitrogen and phosphorus may support harmful algae blooms and loss of seagrasses and coral reefs.
