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.

Tekijä
The development of peatland forests over a 10-year-period (1977-1987) in Satakunta Forestry Board District, Western Finland, is presented, based on the results of the 7th and 8th National Forest Inventories. Over this period the amount of peatlands classified as forest land (MAI over bark over a 100 years rotation ≥ 1 m3ha-1) and the total volume and increment of peatland forests considerably increased, mainly as a result of drainage.
Keywords: Forest drainage, inventory, peatland forests
