Carbon Husbandry

Picture 1. The forests in Kainuu region are typically coniferous forests, under practical silviculture Kainuu region is geographically a central or central-eastern region in Finland. It is forested, scarcely populated region. Forestry is an important source of livelihood in the region. The amount of solid cubic meters in 2011 in Kainuu forests was 163 million cubic meters and 172 million cubic meters in 2016. Correspondingly, the area of forest hectares was 1.930 million hectares and 1.928 million hectares in 2011 and 2016, respectively (NFI 11 and NFI 12 inventories). With average Carbon Multiplier CM = 0.35314 tn C/m3 the total Carbon stock (stems, branches, foliage, roots) in Kainuu was 57.6 million tons in 2011 and 60.7 million tons in 2016. Forest carbon number is calculated by dividing the total carbon stock (c, tn C) at certain time point (t, years) with the forest land area (fl, hectares) at certain time point, for the selected area. (1)     fc(t) = c(t) / fl...

The content of elementary Carbon in the dry biomass is quite constant of 50 per cent, of the dry weight. In simplified calculations this percentage can be used for the dry biomass of trees, for the dry biomass of grasses and cereals as well as the for the young humus in the soil. The coefficient for trees, Carbon multiplier (CM) for calculations of Carbon from solid cubic meters, can be calculated in a similar manner as the  calculation of dry biomass multiplier . Picture 1. Abundant Carbon stock in the Scots pine forest, Kuusamo Also in the total forest growing Carbon stock, it is logical to sum the stems, the branches including the foliage, and the roots. Mathematically the solid cubic meters in the stems (s, cubic meters) can be converted into total Carbon stock (c, tons C) with a coefficient or carbon multiplier (CM). (1)     c = CM * s Calculated as average from the Finnish forest inventories VMI 11 and VMI 12 the Carbon Multiplier is (2)    ...
