Table 12 Average nutrient concentrations (g kg^-1) in branches, assuming larger proportions of fine branch wood (x 1.25) and bark in coarse branch wood (x 1.5), according to this paper and Jacobsen et al. (2003) and relative difference (%) between both datasets (% difference = (this paper/Jacobsen et al. – 1) x 100%)
