Root biomass on an ombrotrophic pine bog and the effects of PK and NPK fertilization.

Finér L. (1991). Root biomass on an ombrotrophic pine bog and the effects of PK and NPK fertilization. Silva Fennica vol. 25 no. 1 article id 5436. https://doi.org/10.14214/sf.a15590


Scots pine (Pinus sylvestris L.) living root biomass (ø≤ 10 mm) 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 biomass of living roots. The length of the pine roots was 2,440 m/m2. The biomass of living roots and root necromass were mostly located in the top 20 cm layer of the soil. The ø < 1 mm 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 root biomass, pine root length and PK (MgB) fertilization did not affect total living root biomass, pine root length, nor the root necromass during the three-year observation period.
