Deployment of Tree Resistance to insects in Short Rotation Biomass Plantations
Short rotation woody crop (SRWC) plantations use fast-growing tree species (such as Populus and Salix) grown under intensively managed conditions much like traditional agricultural crops (Dickmann and Stuart 1983). Typical rotation age ranges from 3-15 years, with the end products including energy and paper (pulp) products. Operational biomass plantations currently use a limited number of clone...
متن کاملPerformance of poplar (populus deltoides bartr.) and its effect on wheat yield under agroforestry system in irrigated agro-ecosystem, India
The quantitative performance of wheat crop under 1-5 year old poplar plantations in irrigated agro-ecosystem was studied to ascertain the biological yield of tree and crop. Results revealed that growth and yield of wheat decreased significantly with the increase in poplar age. The per cent reduction in net grain yield was 17% under one year old poplar plantation, which increased to 52.15% under...
متن کاملUsing short-rotation, intensively managed hardwood plantations as ‘green’ inventory for southeastern U.S. pulp mills
As a routine wood source for a pulp mill, recent studies have shown that intensively managed, short-rotation hardwood plantations are not cost effective. The objective of this study was to determine if these plantations may be cost effective as “green” inventory, replacing some portion of high cost remote woodyard inventory. Three southeastern U.S. pulp mills were used as case studies in a net ...
متن کاملLitter Production Dynamic in relation to Climatic Factors in Tree Plantations
We studied litterfall dynamic of tree plantations in Dez River floodplain, at 14 to 15 years old. The plantations consist of Populus euphratica Oliv., Eucalyptus camaldulensis Dehnh., E. microtheca F. Muell, Acacia farnesiana (L.) Willd., A. salicina Lindl., A. saligna (Labill.) H. Wendl., A. stenophylla Benth. and Dalbergia sissoo Roxb. Litterfall was different between the tree species, and le...
متن کاملAn economic analysis of hardwood fiber production on dryland irrigated sites in the US Southeast
Although there is renewed interest in intensively managed, short-rotation plantations as a source of hardwood for pulp mills, few have been established in the Southeast. Understanding all the costs associated with these plantations will help determine their feasibility. Using a model developed to summarize all the costs, a break-even analysis was completed to determine the delivered cost for pl...
