Factors affecting loblolly pine growth following site preparation
Site preparation is a required silvicultural practice for establishing loblolly pine plantations in the Piedmont physiographic region of the southeastern U.S.; however, relatively little is known about its effect on soil and site factors that influence growth and yield. In this study, the effect of …

DIFFERENT TECHNIQUES FOR DENTAL IMPLANTS SITE PREPARATION: A CONTROLLED CLINICAL TRIAL
… determine whether the application of one implant site preparation protocol (“Step drilling sequence”) could lead to a significantly lower marginal bone resorption as compared to another protocol (“Straight drilling sequence”) at 1-year follow-up. The secondary aims were to evaluate if the tested …

Effects of Site Preparation on Survival and Growth of Planted Loblolly Pine
<p>Effects of site preparation on survival and growth of planted loblolly pine (Pinus taeda L.) on a loblolly-shortleaf pine-hardwood forest site in East Texas are examined by determining the survival and growth of planted loblolly pine, soil chemical characteristics, and density and height of …

Site Preparation Methods For Restoration Of Non-native Pasturelands To Native Upland Habitat
The flatwoods ecosystem of Florida has been heavily depleted over time but remains one of the most important systems to many threatened and endangered species. Areas that have been converted into non-native pastures may be restored to provide not only this invaluable ecosystem but also restore …

Nitrogen dynamics after site preparation in three loblolly pine plantations on the Virginia Piedmont
Intensive site preparation practices and their effect on nitrogen cycling have been implicated as possible causes of productivity declines on forest sites in Australia and New Zealand. This study was initiated in order to determine the effects of site preparation intensity upon N distribution and …

Loblolly Pine and Soil-Site Responses to Harvesting Disturbance and Site Preparation at Stand Closure
… by heavy machinery might diminish long-term soil-site productivity. However, determining the effect of harvesting disturbance and silvicultural treatments on the long-term productivity of pine plantations is difficult because, in addition to harvesting effects, growth distributions are affected by …

Effects of Site Preparation, Seed Germination, and Harvest Maturity on Wiregrass Restoration Efforts at Fort Stewart, GA
… communities and future longleaf pine restoration sites. Many restoration sites are on tracts that have been cleared of all vegetation. Removal of stumps, roots, and debris causes a high level of disturbance to the upper soil layer. Disturbed soil must first be leveled and compacted before …

Physical and Hydrologic Responses of an Intensively Managed Loblolly Pine Plantation to Forest Harvesting and Site Preparation
… past few decades. More recently, harvesting and site preparation practices have become a concern among natural resource managers because intensive forestry practices may alter soil physical properties and site hydrology. These alterations could decrease seedling survival, growth, and future site …

Forest Harvesting Disturbance and Site Preparation Effects on Soil Processes and Vegetation in a Young Pine Plantation
… rutted, deeply rutted and churned), two site preparation treatments (flat planted and bedded) and a gradient of vegetation control (no vegetation control, operational-level weed control and complete weed control). Soil disturbances had relatively small effects on soil quality. Soil …

An Assessment on the Cultivation of Black Cottonwood Cuttings in Nootka Lupine Fields in Conjunction with Site Preparation
… plot. The first year results are reported here. Site preparation was effective in increasing survival and growth of planted cuttings at both sites. Rotavation generally was the most effective method employed as it provided the cottonwood plants with early relief from competing vegetation. Clone …

Loblolly Pine (Pinus taeda L.) Plantation Response to Mechanical Site Preparation in the South Carolina and Georgia Piedmont
Site preparation is fundamental for establishing loblolly pine (Pinus taeda L.) plantations, but long-term sustainability of plantations established using mechanical treatments is in question because of concerns regarding soil tillage and the removal of harvest residue and soil organic matter. A …

The impact of harvesting and site preparation on nutrient dynamics, soil erosion and stream water quality in the Virginia Piedmont
… harvesting and four intensities of mechanical site preparation were evaluated in the Virginia Piedmont using gauged watersheds. The four treatments were: 1) control, 2) chop and burn, 3) shear-disc, and 4) shear, rake-pile, disc. A combination of soil solution, streamwater and soil sampling and …

Loblolly Pine Growth and Competition Response to Varied Chemical Site Preparation Treatments 14 Years After Establishment in the Piedmont of Virginia
Chemical site preparation is used to enhance the productivity of loblolly pine plantations; however, it is most often combined with other methods and/or chemical release, and has been studied little on its own. Our study, conducted in the Virginia piedmont, compares the effects of various site …

Timber Harvesting and Site Preparation Effects on Soil Quality for Loblolly Pine Growing on the Lower Coastal Plain of South Carolina
… times each year. Harvesting timber under wet site conditions often results in extensive soil compaction, rutting, soil displacement, and waterlogging. Forest managers are concerned that these visually-displeasing soil disturbances may cause site damage and reduced productivity. These concerns …

Slash Mulching and Incorporation as Mechanical Site Preparation for Pine Plantation Establishment and Subsequent Effects on Soil Moisture and Site Hydrology
… adverse effects on soil physical properties, site hydrology, and overall site productivity. Substantial quantities of wood residues are often left on these sites by timber harvesting operations, and it was hypothesized that the incorporation of this slash into the soil could improve the soil …

Effects of hydrology-altering site preparation and fertilization/release on plant diversity and productivity in pine plantations in the coastal plain of Virginia
… in Virginia. The study area consisted of three sites in the Coastal Plain. The sites were originally established in 1969 to study the effects of various treatments on loblolly pine growth. The three treatments applied were chop and burn, bedding, and ditching. Fertilization subplots of P, N and …

Long term effects of wet site timber harvesting and site preparation on soil properties and loblolly pine (Pinus taeda L.) productivity in the lower Atlantic Coastal Plain
… that ground based timber harvesting on wet sites can alter soil properties and inhibit early survival and growth of seedlings. Persistence of such negative effects may translate to losses in forest productivity over a rotation. During the fall and winter of 1989, numerous salvage logging …

The Effects of Mechanical Site Preparation Treatment and Species Selection on Survival and Carbon Pools in 12-Year-Old American Sycamore (<i>Platanus occidentalis</i>) and Willow Oak (<i>Quercus phellos</i>) Riparian Plantations in the Southeastern U.S. Piedmont
… species that are not well suited to the wetland sites, inadequate planting densities, soil compaction associated with former agricultural activities, lack of microtopographic relief that allow small seedling to survive on wet sites, competition by herbaceous plants, and browse. Selection of …

Mitigation of harvesting disturbances on a forested wetland in the South Carolina lower coastal plain
Wet site timber harvesting often results in rutted and/or compacted soils. These impacts damage inherent site and soil properties and can reduce subsequent pine seedling survival and growth. Site preparation treatments such as bedding, disking, and fertilization are often employed on harvested …
