چکیده
In this study, the authors provide a direct comparison made between whole tree-harvesting (WTH) and cut-to length (CTL) methods, which was conducted in two sites Slovak Republic applied to poplar plantations. Both systems, WTH CTL, have been employed at highest mechanization level sites: “Nivky” “Skalica”. Two different strategies, namely, “mass handling” “small-scale mechanization”, used for respectively. The study results showed that of productivity (ODT SMH−1) felling operation almost double than CTL method Nivky (+84%) more Skalica (+113%). extraction under increase from one fifth (+20%) (104%) sites, Regarding cost-efficiency (EUR ODT−1), system offers similar trend except with respect (higher site), 4.5% less expensive extraction. show mass-handling technique deployed very good performance poorer plantations since small tree size low-growing stock challenge system. total (felling, bucking, extraction) costs ODT−1) recorded by commercial conditions (as contractors perform revenue purposes) were 32.50 45.80 EUR ODT−1 43.30 53.60 higher-yield site (Nivky) lower-yield (Skalica), System, researchers found drop efficiency (and consequent rise costs-per-ton product) depends largely on bucking phase using harvester landing stacked piles interlocked trees. main demonstrate promising strategy mass handling associated medium rotation coppice (MRC) harvesting shows is weaker phase.

Harvesting Short-Rotation Poplar Plantations for Biomass Production
Nacrtak In Italy, short rotation forest has become very popular in recent years, with over 4,000 hectares already planted – almost exclusively with clone poplar. The study models the performance of modified forage harvesters on a range of short-rotation poplar plantations, identifies technical obstacles to the deployment of these machines and suggests solutions that may expand the capability of...
متن کاملHarvesting Systems and Costs for Short Rotation Poplar
The objective of this review is to compare the cost of coppice and longer rotation poplar harvesting technology. Harvesting technology for short rotation poplar has evolved over the years to address both coppice harvest and single-stem harvest systems. Two potential approaches for coppice harvesting are modified forage harvesters and modified mulcher-balers. Both of these systems effectively ha...
متن کاملA Single-pass Reduced Tillage Technique for the Establishment of Short-Rotation Poplar (Populus spp.) Plantations
In Italy, there has been a significant increase of the areas cultivated with short-rotation forestry (SRF) poplar (Populus spp.) for the production of lignocellulosic biomass. This species has been generally introduced on soils managed with conventional farming practices that led to the formation of a hardpan. This constitutes a serious obstacle for root development and water availability, whic...
متن کاملGene flow and simulation of transgene dispersal from hybrid poplar plantations.
Gene flow is a primary determinant of potential ecological impacts of transgenic trees. However, gene flow is a complex process that must be assessed in the context of realistic genetic, management, and environmental conditions. We measured gene flow from hybrid poplar plantations using morphological and genetic markers, and developed a spatially explicit landscape model to simulate pollination...
متن کاملHarvesting Costs and Utilization of Hardwood Plantations’
The use of short rotation, intensive culture (SRIC) practices in hardwoods to meet fiber supply needs is becoming increasingly widespread. Total plated area of short rotation hardwood fiber plantations is currently about 22,OfKI ha (McDonald and Stokes 1993). That figure should certainly to grow in response to public concerns over loss of natural hardwood stands. With many of the plantations cu...
