Published: Feb. 20, 2024
After a period of significant development, poplar cultivation in Italy has been rapid decline since the 1980s. Because its marked ductility, is valuable for both wood furniture and energy production. Production could be increased through mechanization, because innovative machinery equipment can reduce exposure forest workers to common risk factors, ensure greater better productivity, increase efficiency operations, costs. There are various systems mechanization production (from traditional advanced pushed mechanization). We describe range possibilities (in terms techniques adopted machines used) planting, harvesting, chopping poplar. Based on our analysis operating costs, we conclude that mechanized average cost per ton chips (EUR/t) by 23% gross hectare produced (EUR/ha) 37%.

Considering the increasing need to produce energy from renewable sources, interest towards Medium Rotation Coppices (MRC) plantations has increased. One of main issues that require tackling for comprehensive sustainability these is related development sustainable harvesting systems. Indeed, as a consequence average tree diameters at breast height (dbh) about 15 cm, single-pass typical short rotation coppice not applicable. Therefore, are generally harvested with machinery specifically developed forest operations, instance harvesters, feller-bunchers and forwarders. In Mediterranean area, availability such machines still limited few big enterprises. majority contractors carry out their activities in framework small-scale forestry, without financial possibility purchasing expensive machineries. Thus, present study had objective evaluate performance two systems 7-year-old poplar plantation Central Italy. The difference between was different applied wood extraction, i.e., forestry-fitted farm tractor equipped winch (WINCH) fork lift prototype, attached crawler (CFL). Extraction via CFL system reached very high working 21.5 m3 SMH−1 (Scheduled Machine Hours, including delays), comparable productivities reported literature forwarders similar plantations. Harvesting costs were 24.74 EUR m−3, which 4.48 m−3 felling chainsaw, 4.61 extraction prototype 15.64 chipping.
