| Abstract | At two experimental coniferous forest sites in south-central Sweden, soil chemistry was examined following the application of different doses of self-hardened and crushed wood ash and a pelleted wood ash. One site was covered by a mixed Picea abies/Pinus sylvestris stand growing on a podzolized soil, and the other was dominated by P. sylvestris growing on a podzolized soil. Wood ash was applied in September 1995 at rates of 3, 6, and 9 ton/ha. Results are presented in terms of pH, calcium, magnesium, potassium, phosphorus, nitrogen, and carbon contents. Ash-induced increases in pH and extractable amounts of Ca and Mg in the humus layer were observed following ash application. Large differences in the recovery of applied nutrients were observed between the two sites, however. No effects on total N and C contents were noted, but there was a significant ash dose effect for ammonium in the humus layer at the pine site but not at the mixed site. When compared at the same ash dose, the effects on soil chemistry of the two different ash formations did not differ significantly. |
