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 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 کاملThe Effects of Changes in Loblolly Pine Biomass and Soil Moisture on ERS-1 SAR Backscatter
E r young (< 15 years old) lobloUy pine stands at Duke Forest (North Carolina, USA), when the ground was wet, the observed ERS-1 SAR backscatter from short-grass fields of 0.05 kg /m 2 biomass was >~ the backscatter from the stands, and there was no significant correlation between the backscatter and biomass (r 2 = 0.19). Under dry soil conditions, the backscatter increased about 2-3 dB as the ...
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 کاملFertilization 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...
