Abstract The nutrient requirements of the phytoplankton of the Potomac Estuary were studied during the summer of 1977 employing the following laboratory tests: NH4(t)-N uptake, alkaline phosphatase enzyme activity; extractable surplus orthophosphate; tissue analysis for carbon, nitrogen and phosphorus content; and nitrogen fixation by acetylene reduction. The results indicated that the bloom of Oscillatoria was limited by nitrogen and that adequate phosphorus was present.
