Table 14 Average nutrient concentrations in stem wood (without bark, g kg-1) according to Jacobsen et al. (2003) and this paper and relative difference (%) between both datasets (difference (%) = this paper/Jacobsen et al. – 1) x 100%). Silver birch is not given in Jacobsen et al. (2003). Japanese larch, Douglas firs, Scots pine and common oak are calculated from mass proportions of sapwood and heartwood
