    High productivity of fertilized loblolly pine (Pinus taeda L.) plantations in the southern United States is related to increased leaf area index (LAI), but higher evaporative leaf surface area may increase drought determine if the benefits of fertilization are affected by water availability or the effects of drought are exacerbated by fertilization, the interactive effects of. Loblolly pine (Pinus taeda L.) is the most important timber-producing tree species in Arkansas and the South as a whole. Loblolly pine naturally occurs primarily in the coastal plain region of the southern United States. In Arkansas, this region comprises the southwest third of the state (Figure 1). Though loblolly pine is native to.

      Stemflow is an essential hydrologic process shaping the soil of forests by providing a concentrated input of rainwater and solutions. However, the transport of metazoans by stemflow has yet to be investigated. This 8-week study documented the organisms (stemflow of different tree species. Because the texture of the tree bark is a crucial determination of stemflow, . and yield of loblolly pine plantations have been studied by many scientists over the years with the common conclusion that tree spacing is one of the most important factors in forest management. Researchers have recommended a fi-nancially optimal rotation age, the number, timing, and intensity of thinnings for loblolly pine (Huang and Kronrad.

Sampling Throughfall and Stemflow in Young Loblolly Pine Plantations S.J. Zarnoch, D.A. Abrahamson, and P.M. Dougherty Abstract Throughfall and stemflow estimates were obtained on a rain-event basis for small (hectare) plots established in a young loblolly pine (Pinus taeda L.) plantation in North Carolina.

Throughfall and stemflow estimates were obtained on a rain-event basis for small (hectare) plots established in a young loblolly pine (Pinus taeda L.) plantation in North Carolina. The plots were exposed to specific fertilization and irrigation treatments, which resulted in a wide range of basal areas and leaf area by: 2.

To examine the spatial variability of rainfall under a 12‐year‐old pine plantation in a subtropical coastal area of Australia, we observed gross rainfall, throughfall and stemflow over a 1‐year period.

Our results show that the spatial variability of gross rainfall within a 50 m × 50 m plot is minimal. loblolly pine [Allen, ]. We used site measurements of leaf area index (LAI) and basal area (BA) in the regression models of throughfall and stemflow that were measured throughout the study period.

The spatial autocorrelation of throughfall measurements beneath the canopy was assessed by computing the variograms of throughfall for a range of storms. Fertilizer and irrigation treatments were applied in a 7‐ to 10‐year‐old loblolly pine (Pinus taeda L.) plantation on a sandy soil near Laurinburg, North Carolina.

Rainfall, throughfall, stemflow, and soil water content were measured throughout the study period. Monthly interception losses ranged from 4.

Accelerated tree growth under elevatedatmospheric CO2 concentrations may influencenutrient cycling in forests by (i) increasingthe total leaf area, (ii) increasing the supplyof soluble carbohydrate in leaf tissue, and (iii) increasing nutrient-use efficiency.

The impact of fertilizer application on the growth and water relations of loblolly pine has been investigated by numerous studies; however, few field experiments have examined the effects of drought.

In a 6-year-old loblolly pine plantation, we applied a throughfall reduction treatment (ambient vs. ~30% throughfall reduction) and a fertilization treatment (no fertilization vs. fertilization). Over 28 months, throughfall reduction lowered soil moisture for all depths and differences were significant in the surface soils (0– m) (–3.
