Abstract:
Calibration-period/control-area approach was used to study nitrogen and phosphorus
export from drained and productive Norway-spruce-dominated peatland forests follow-
ing conventional stem-only and whole-tree harvesting. The study indicated high nitrogen
and particulate phosphorus exports and lack of significant differences between the harvest
treatments during the first 3–4 years after harvesting. The high extra nitrogen exports,
increasing to a maximum level of about 10 kg
ha–1 during the third year after harvesting,
were partly caused by the higher nitrate export than in previous studies. The study has
a practical outcome that management of harvest residues (i.e. left on site or harvested)
may not be an efficient means of mitigation of nitrogen and phosphorus exports. The high
exports following harvesting underline the importance of using the best available water
protection methods, such as sufficiently large wetland buffer areas, to decrease nutrient
exports to watercourses from productive Norway spruce dominated peatland catchments.
