Research Strategies for Increasing Productivity of Intensively Managed Forest Plantations
2009) and estimated to average 89% nationally (Ice et al. in press). Information is needed to successfully address the confluence of technological, biophysical, and environmental issues surrounding intensively managed forests. This overview describes current intensive plantation management practices in the United States and their role in increasing forest productivity. Although a number of plan...
متن کاملRapid Indices of Potential Nitrogen Mineralization for Intensively Managed Hardwood Plantations
Short-rotation hardwood plantations generally require repeated applications of nitrogen (N) fertilizer to maintain desired growth and are being installed on two previous land uses: agricultural fields and cutover forest lands. Because the soil organic matter chemistry is different between agricultural field and cutover soils, indices of N availability developed for one land use or the other may...
متن کاملDevelopment of a Hybrid Modeling Framework for Intensively Managed Douglas-Fir Plantations in the Pacific Northwest.
approved: Douglas A. Maguire Forest growth models in the Pacific Northwest are predominantly empirical. Predictions of yield under alternative silvicultural regimes cannot rely completely on field trials; yet empirical growth models are often inadequate for extrapolating untested regimes and genotypes. The limitations of current models include (1) long time-steps (e.g. 5-10 years); (2) insuffic...
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 کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
