Growth and Competition Response in Intensively Established Loblolly Pine Plantations at Crown Closure

High Tonnage Harvesting and Skidding for Loblolly Pine Energy Plantations

The southeastern United States has a promising source for renewable energy in the form of woody biomass. To meet the energy needs, energy plantations will likely be utilized. These plantations will contain a high density of small-stem pine trees. Since the stems are relatively small when compared with traditional product removal, the harvesting costs will increase. The purpose of this research ...

Growth and Yield Relative to Competition for Loblolly Pine Plantations to Midrotation- A Southeastern United States Regional Study

Lohlollypine (Pinus taeda LJplantations were studied across 13 southeastern sites grown for 1.5 yr with near-complete control o f woody, herbaceous, and woody plus herbaceous components during the f irst 3-5 yr . This mult iple object ive experiment ( the COMProject) documents stand dynamics at the extreme corners o f the response surface that encompasses most compet i t ion condi t ions common...

Effects of mass inoculation on induced oleoresin response in intensively managed loblolly pine.

Oleoresin flow is an important factor in the resistance of pines to attack by southern pine beetle, Dendroctonus frontalis Zimm., and its associated fungi. Abiotic factors, such as nutrient supply and water relations, have the potential to modify this plant-insect-fungus interaction; however, little is known of the effects of inoculation with beetle-associated fungi on oleoresin flow. We observ...

Fertilization Increases Below-ground Carbon Sequestration of Loblolly Pine Plantations

The extent of fertilization of southern pine forests is increasing rapidly; industrial fertilization increased from 16,200 ha per year in 1988, to 344,250 ha in 1998. Fertilization increases stand productivity and can increase carbon (C) sequestration by: 1) increasing above-ground standing C; 2) increasing C stored in forest products; and 3) increasing below-ground C pools. This talk will conc...
