… nutritional values and suitable pH. Since many of these are being planted with Norwegian spruce today, when evaluating poplar, comparisons should be made against the production of these. To try to predict the potential of production and survival we have looked at the only three …
… of this study was to examine and describe the chloride concentration of Norwegian spruce (Picea abies L. Karst.) in the south of Sweden. Furthermore the aim was to be able to predict chloride concentration from readily measurable site factors. Samples were collected from 8 plots …
