,Wood Ash Recycling – Possibilities And Risks, fractions (branches, tops, needles) that were earlier left to decay in the forest. Although they only amount to a small proportion of the total weight of the tree, these fractions have a much higher nutrient concentration per unit weight than the stemwood. Thus, the increased nutrient export follow
