  • Productivity and cost assessment of two harvesting methods for medium-rotation poplar plantations [Elektronski vir]
    Spinelli, Raffaele, gozdar ...
    The study compared the cut-to-length (CTL) and the whole-tree-harvesting (WTH) methods undertwo alternative log length specifications (2 m vs. 4 m) as deployed in the new medium-rotationpoplar ... plantations. The goal of this study was to determine if any of the four combinations ofharvesting method and log length incurred lower cost and/or better log yield than the others. Thetest was conducted in a 6-year-old plantation with a stocking between 30 and 60 bone-dry tons(BDT) per hectare. Each treatment was repeated 8 times–each repetition consisting of onesample plot with a 700 m2surface area (115–130 trees). Researchers determined the massobtained from each sample plot, as well as the time necessary to turn standing trees into logs andbiomass piled at the landing. A calculator was developed for estimating harvesting costs as afunction of variable machine rates. Under the conditions of the study, CTL harvesting into 4-mlong logs was the most effective solution, because it offered a better log yield compared withWTH (60% vs. 50%) and incurred the same harvesting cost (∼33€BDT−1). Shortening log lengthto 2 m determined a 25% increase of harvesting cost
