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 کاملCompilation of State-of-the-Art Mechanization Technologies for Short-Rotation Woody Crop Production
SUMMARY This report reviews the current state of mechanization of operations, from establishment through harvesting and transportation, for short-rotation hardwood plantations. Given that essentially all of the high production plantations in the U.S. are intended for pulp production, with residues for energy as a secondary product, the report focuses mainly on approaches for producing trees gre...
متن کاملShort Rotation Woody Crops for Industrial Applications
Purpose-grown trees have the potential to be a significant portion of the bioenergy solution in the Southeastern United States. Trees are a biomass source with existing end-use markets and associated infrastructure and provide a “living inventory” with a variety of benefits over annually harvested energy crops. The economic feasibility of utilizing tree woody biomass is improved by increasing p...
متن کاملA STELLA Model to Estimate Water and Nitrogen Dynamics in a Short-Rotation Woody Crop Plantation.
Although short-rotation woody crop biomass production technology has demonstrated a promising potential to supply feedstocks for bioenergy production, the water and nutrient processes in the woody crop planation ecosystem are poorly understood. In this study, a computer model was developed to estimate the dynamics of water and nitrogen (N) species (e.g., NH-N, NO-N, particulate organic N, and s...
متن کاملA STELLA Model to Estimate Soil CO2 Emissions from a Short-Rotation Woody Crop
The potential for climatic factors as well as soil–plant–climate interactions to change as a result of rising levels of atmospheric CO2 concentration is an issue of increasing international environmental concern. Agricultural and forest practices and managements may be important contributors to mitigating elevated atmospheric CO2 concentrations. A computer model was developed using the Structur...
