Sažetak
The influence on the algal growth potential (AGP) due to the addition of nutrients (nitrates and phosphates) to the original water samples was investigated by the method of bioassay. The results of the AGP were compared with in situ limiting nutrients. The case study was done in two different ecosystems - Stara Drava (part of the hydromelioration system) and Lake Sakadaš (part of the wetland ecosystem of Kopački rit Nature Park). The obtained results showed that in cases when nitrates were the limiting nutrient in in situ conditions (at site I of the Stara Drava), the adding of higher concentrations of nitrates (N2 and N3) in experimental conditions stimulated the growth of the AGP of Chlorella kessleri. In cases when phosphates were the limiting nutrient in in situ conditions (Lake Sakadaš), the adding of all three concentrations of nitrates did not influence on the growth of the dry weight (DW), but the adding of phosphates stimulated the AGP.
