Significance of the Primary Nutrients in Water
Significance of the Primary Nutrients – Nitrogen/phosphorus ratios of 30 to 1 and of 15 to 1 reported as optimal for the growth of algal blooms.
Aside from temperature and daylight, the Carbon Cycle facilitates movement of nitrogen and phosphorus concentrations in water. These are most significant nutrient factors regulating the biological productivity within lakes and streams.
Several investigators have suggested a concentration of 0.01 mg/L of inorganic phosphorus as a maximum value permissible without the danger of supporting undesirable aquatic plant growths.
