Soil CO, evolution and root respiration in 11 year-old loblolly pine (Pinus Weda) plantations as affected by moisture and nutrient availability
We measured soil CO, evolution rates with (S,) and without (S,,) the forest floor litter and root respiration monthly in 11-year-old loblolly pine (Pinus tueda L.) plantations during the fourth year of fertilization and irrigation treatments. Values of Srr ranged from less than 1 * pmol.ms -’ during the winter to greater than 5 pmol.m-‘s-l in late spring. Average Srr was significantly greater i...
متن کاملLong term growth responses of loblolly pine to optimal nutrient and water resource availability
A factorial combination of four treatments (control (CW), optimal growing season water availability (IW), optimum nutrient availability (FW), and combined optimum water and nutrient availability (FIW)) in four replications were initiated in an 8-yearold Pinus taeda stand growing on a droughty, nutrient-poor, sandy site in Scotland County, NC and maintained for 9 years. Results for the first 4 y...
متن کاملSoil Co2 Efflux and Soil Carbon Content as Influenced by Thinning in Loblolly Pine Plantations on the Piedmont of Virginia
The thinning of loblolly pine plantations has a great potential to influence the fluxes and storage of carbon within managed stands. This study looked at the effects of thinning on aboveground carbon and mineral soil carbon storage, 14-years after the thinning of an 8-year-old loblolly pine plantation on the piedmont of Virginia. The study also examined soil respiration for one year following t...
متن کاملHigh 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 ...
متن کاملAluminum fractions in root tips of slash pine and loblolly pine families differing in Al resistance.
Aluminum (Al) distribution among several cellular fractions was investigated in root tips of seedlings of one Al-resistant and one Al-sensitive family of slash pine (Pinus elliottii Engelm.) and loblolly pine (Pinus taeda L.) grown in nutrient solution containing 100 microM AlCl3 (pH 4) for 167 h. Aluminum present in 5-mm-long root tips was fractionated into cell-wall-labile (desorbed in 0.5 mM...
