The soil acid-based status of black spruce forests was examined as a function of different harvesting techniques. Soil was compared from five pairs of whole-tree and stem-only harvests. The enrichment of the exchangeable base cation pool occurred with stem-only harvesting. There was little difference between the treatments in mineral soil, possibly because the high levels of Al in these acidic soils inhibited cationic exchange reactions. While the treatment effects may not be sustained over time, the initial boost in base cation nutrition may improve early development.
