THE IMPACT OF LOG LENGTH ON THE CONVERSION FACTOR OF STACKED WOOD TO SOLID CONTENT

The purpose of this paper is to determine the conversion factors of stacked wood to solid content in common hornbeam, European beech and oak for logs with the length of 2 and 3 m, and, to test a new method for the determination of the respective conversion factors. The conversion factor was determined by the xylometric and the diagonal method. For comparison, a third method, called the - surface method, suggested by the authors, was introduced. The results obtained allow a classification of the methods mentioned above according to their precision considering the values obtained by the xylometric method as reference values. Methods are classified in the following order: Surface method (± 3 %) and diagonal method (0 to 27 %).
