Influence of sodium humate on the growth of Scenedesmus quadricauda (Turp. Brèb.) and Gonium pectorale in the case of different calciumand iron doses

Krystyna Juraja


The influence of sodium humate on calcium and iron uptake by two species of algae was studied. It was found that sodium humate influence differentially the growth of these algae in various culture conditions by regulating the iron uptake. The action of sodium humate is especially favourable in non optimal pH of the medium and its effectiveness increases with time.
