- AbstractScots pine living root biomass (Formel) was 640 g/m2 on the studied low- shrub pine bog before fertilization, and that of the ground vegetation almost the same. The total root necromass was 23% of the living root biomass. The length of pine roots was 2440 m/m2. The living root biomass and root necromass were superficial. The (Formel) pine root fraction accounted for almost 90% of the pine root length; in contrast, over 50% of the biomass was in the 1-10 mm thick roots. The NPK(MgB) and PK(MgB) fertilizations did not affect living root biomass, pine root length, nor the root necromass during the three-year observation period.
