dc.description.abstract Removal of stumps and fertilization after harvesting have been proposed to reduce root diseases in succeeding stands. Potential impacts such as compaction and loss of soil C or N could limit the use of this technique. This research examined forest soils and foliar nutrient levels in five Pacific Northwest stands 22-29 years after stump removal and fertilization with N. A non-significant trend of lower foliar N was also observed with stump removal. These results were consistent in all five soil types. This reduction in the organic component of the soil may be a concern for nutrient cycling and long-term productivity on poor sites. en_US
