Carbon-depleting ability of scotch pine cultures overland phytomass (Pinus sylvestris L.) of medium-taiga forest area

The aim of the study was to assess carbon-depleting abil- ity of phytomass fractions of artificial pine plantations by forest types. The researches were carried out in the mid-taiga forest zone of the taiga forest area in the European part of Russia (Vologda Region, Babaevsky district). The objects of the re- search were pure artificial pine-tree stands, created by seed- ing method in various forest-growing conditions. On trial plots, 10 model trees were selected, which were divided into frac- tions: dry branches, living branches, tree greens (shoots with needles with a diameter at the base of no more than 0.8 cm), bark trunk, wood trunk. Fraction mass was measured by an electronic steelyard with an accuracy of 50 g. The reserves of the carbon deposited by woody layer of studied pine forests defined were determined that in 1 kg of absolutely dry mass of dry boughs, branches, bark and wood 0.5 kg of carbon, and contain in 1 kg of absolutely dry mass of woody greens -0.45 kg...
