The last possessed a higher content of trace elements, e.g. iron, lead, copper, manganese and chromium, which would inhibit the growth of both flora, although a rather higher content of macronutrients also existed.</p><p>According to the above results, it was concluded that cultivation of unicellular green algae in soil extracts may be used for assessing the chemical contents of the soils.
