Experimental Study of the Effect of Nutrients on Phytoplankton of the Shallow Highly Eutrophic Lake Nero

Experimental studies of the effect of phosphorus, nitrogen, and silicon on the phytoplankton of the shallow highly eutrophic Lake Nero have been carried out. It is shown that the enrichment of lake water with nitrogen leads to an increased concentration of chlorophyll a and the growth of the biomass of dominant algae species. Phosphorus limits the abundance of a certain species of algae; the limiting role of silicon in the development of spring phytoplankton has not been experimentaly confirmed.
