Abstract
ⶠPhosphorus and base cations (K, Ca, and Mg) are released slowly from decomposing Scots pine, Norway spruce and silver birch stumps. ⶠThe absolute amounts of phosphorus in stumps increased during decomposition. The accumulation of phosphorus is probably mainly due to that decomposer fungi transport phosphorus into stumps from the surrounding soil. ⶠBy serving as a nutrient sink and long-term nutrient pool with a slow release rate, stumps can potentially contribute to the retention of nutrients and decrease the leaching of nutrients from the forest ecosystem after clear-cutting. ⶠThe results suggest that when one practises stump harvesting, nutrients are not only removed from the system through harvested biomass, but stump harvesting may also promote the leaching of nutrients.
