English title: Discharge water quality from old ditch networks in Finnish peatland forestsTiivistelmä
Runoff water from 75 Finnish ditch networks was sampled for chemical analysis in 1990-1992. In total, 2815 samples were analyzed. Higher mean and median concentrations of total dissolved phosphorus were observed than reported earlier. Except for phosphorus, concentration of most elements increased with increasing site fertility. No clear relationship between phosphorus concentration and the site characteristics could be detected. The median concentration of suspended solids in runoff water from old ditch networks was as low as 2.4 mg l-1.
