Comparison of technologies of wood biomass utilization in beech stands : doctoral dissertation = Primerjava tehnologij izkoriščanja lesne biomase v bukovih sestojih : doktorska disertacijaMarčeta, DaneIn this research were compared two harvesting methods. First method was felling the tree, processing it at the stump, and extraction the assortments to the landing site. Second was felling the tree, ... partially processing at the stump and skidding to the landing site where processing was finished. First harvesting method was understood as the assortment method (short-wood) and second as the half-tree length method (long-wood) as a modification of the tree-length method. The aim of the research was to identify advantages and disadvantages of introducing the half-tree-length method and the need for eventually modification of the present short-wood (assortment) method. It was examined possibilities for rational chipping of fuelwood and wood residues which occurred after processing at the landing site in half-tree length method. Investigation was conducted in the area of municipality Ribnik, Republic of Srpska, Bosnia and Herzegovina. Results showed that productivity of cutting was higher in the half-tree length method than in the assortment because some working operations were avoided or minimized in half-tree length method, like production and stacking of fuelwood. Costs of skidding were significantly lower in the half-tree length method. Within the same stand conditions, the average damage surface was larger on sample plots with the half-tree length harvesting method. The amount of residue which left after processing at the landing site in half-tree length method was 2 m3 on 100 m3 of roundwood. Investigation of productivity and cost calculation of chippers showed that chippers with bigger capacity had lower unit costs, but because of inability to achieve full capacity at forest landing site and because of their dimensions which hinder the manipulation, it can be recommended using of chippers of smaller capacity.Type of material - dissertation ; adult, seriousPublication and manufacture - Ljubljana : [D.
