Summary Under the above title we published in Šumarski list, No. 3—4/1987 (as part one) an original scientific paper based on investigations carried out on fir trees. In this second part the results of our investigations conducted on oak trees are published under the same title. We selected these wood species because fir is our most waluable species in mountain forests and onak in low- lying forests. For these investigations we took oak veneer- and saw-logs from regular annual fellings, altogether approx. 320 cu. m., by using the random sample method, and had them processeg in appropriate woodworking plants. The felled stock was selected strictly according to the Yugoslav Standards (JUS) for these assortiments; it was processed and classified also according to JUS into specific quality and dimension classes and purchased at prices specified in the sawn- timber Price List. We determinated the calue the processed stock on the basis of its quality and thickness structure and the respective selling prices. All the value-data are given in Tables 1 to 8 and in Figures 1 and 2, and the cost structure (the procurement amd Iprocessing of raw materials) in Table 9. In concluding Table 10 a synthesis of the results of our investigations is given. They only relate to our experiment, but can also be applied to day-to-day production, provided production is carried out under the same condition and the same raw material is used as in our experiment. If the raw material is of a poorer quality the results will also be poorer, and if it is of a better quality then ours, the rekults will be better. In any case, on the basis of our ezperiment we have found that forestry can through primary mechanical processing sell at a good price all felled saw- logs and partlyachieve profit for itself, while primary mechanical processing plants achieve in turn above-the-average profits at the expanse of forestry, on 611 |
