Concentrations of dissolved organic carbon (DOC), dissolved organic nitrogen (DON), ammonium (NH4), phosphate (PO4) and nitrate (NO3) in the treatments at the beginning of the experiments for the control, the agriculture river water treatment (DOMagri) and the humic river water treatment (DOMhum). Standard deviations in parentheses. Time evolution of inorganic nutrients can be found in Markussen et al. (2018; Figure S4).
