Here, we report a laboratory experiment performed with the water from the Don river. Our aim was to examine the effect of NH4VO3 in concentrations of 0.5, 5, 25, and 100 ?g/L of Vanadium (V) on the phytoplankton growth indicators in the absence of their growth limitation by Nitrogen (N) and Phosphorus (P), as well as on the metabolism intensity indicators of plankton communities: biochemical oxygen demand (BOD5) and alkaline phosphatase activity (APA). The stimulating effect on the phytoplankton abundance and biom...
