SUMMARY
Most earlier Swedish and Finnish experiences of the effects of wood ash on soil productivity on peatlands, are strongly positive. Investigations of the environmental effects, for example water quality and net effects on climate forcing gases, have so far not indicated reasons to refrain from this silvicultural measure. There is, however, still a need for further confirmation of these conclusions. Here, we report the effects of ash fertilization on the groundwater and on the nutrient status of pine (Pinus Silvestris (L.)) needles, three years after ash treatment, on five old-drained and forested peatlands in Northern Sweden. The series of trial areas comprises five sites, spread from lat. 62o N to 64.5o N. All sites have moderately deep…
