Both fertilizing and water-table control significantly increased height and biomass of slash (Pinus elliottii var. elliottii Engelm.) and loblolly (Pinus taeda L.) pines on a Leon soil formed over marine sands, strongly acid, low in nutrients and with a spodic horizon in the cm zone. The effects of the treatments were by: Both fertilizer application and control of the water table significantly increased the height and biomass of Pinus elliottii var.

Abstract. Fertilization is a silvicultural practice used for increasing forestland productivity in the southern U.S. Effective operational use of fertilizers requires diagnostic systems, used individually or in combination, that accurately identify site nutrient status, needs, and potential by: Long-Term Effects of Site Preparation Treatments, Complete Competition Control, and Repeated Fertilization on Growth of Slash Pine Plantations in the Flatwoods of the Southeastern United States.
The most widely used NPK fertilizers for pine straw production are listed in Table 2. Urea is the most frequently used nitrogen fertilizer in southern pine silviculture because of its high N concentration and competitive price. However, as urea degrades, it releases ammonium (NH 4 +) ions and ammonia gas (NH 3).
Ammonia is subject to volatile.

Slash pine is an important commercial conifer that grows on the coastal plains of the southeastern United States (∼ latitude 30°N) in soils that generally have shallow water seems to be less of a limiting factor to stand growth than nutrient (nitrogen) supply (Gholz et al., ).Stand fertilization with N, P, K, and ground limestone applied quarterly over 4 years caused an.
Fertilization is used to correct inherent site nutrient deficiencies such a limited phosphorus on wet flatwoods sites and on some upland coastal plain sites, to boost growth of established plantations, and to replace nutrients removed in pine straw harvests. These sites were originally established by the USDA Forest Service and Union Camp Corporation to evaluate the effects of three site preparation treatments on water table levels, seedling survival and growth on wet flats near Franklin, Virginia (Young,Langdon, ).InVirginia Polytechnic Institute and State University superimposed a fertilization study over the original study.

Forests in the Southeast USA are predicted to experience a moderate decrease in precipitation inputs over this century that may result in soil water deficiency during the growing season.
The potential impact of a drier climate on the productivity of managed loblolly pine (Pinus taeda L.) plantations in the Southeast USA is uncertain. Access to water reserves in deep soil during drought. Pine production in Florida, as well as in much of the lower flatwoods region-a region characterized by flat to undulating topography, high fluctuating water tables, and generally coarse, sandy topsoils, except where broken by lakes, sinkholes, and of 3-year-old trees in site preparation-fertilization Site Preparation Avg.
Control Disced. In general, fertilizers are not recommended for pine plantations in the sandhills due to moisture limitations. However, lb DAP/acre may be effectively used on young sand pine, while urea is sometimes recommended for older stands of sand pine on excessively drained sands.

This is normally done during the site preparation and bedding operation using ground rock phosphate, triple super phosphate, and ordinary super phosphate. P applied at planting has a long lasting response of 15 to 20 years. However, on sites with a shallow water table bedding will increase rooting space, aeration and increase seedling survival and growth.
On droughty sites, bedding can be used if the site is irrigated and vegetation is controlled. These treatments are the standard for contemporary slash pine plantation management.
Control of weeds, woody shrub, and. Loblolly pine (Pinus taeda L.) forests are of great ecological and economic value in the southeastern United States, where nutrient availability frequently limits productivity.
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.
the productivity of loblolly pine (Pinus taeda L.) over a period approximately equal to a pulpwood rotation (18 years). The experiment consisted of a 2 x 2 factorial combination of complete and sustained weed control and annual fertilization.
Rainfall and evapotranspiration are the major water input and output respectively, of pine flatwoods ecosystems. Water movement in pine flatwoods ecosystems can be modeled adequately by a coupled surface-subsurface forest hydrological model.
Specific tasks were as follows: 1. Hydrologic variables used in this assessment include water table level, drainage, and storm flow on different spatial and temporal scales. hydrology of pine flatwoods in Florida. Water Resour.

All explained in a clear, easy-to-read manner. Click here for the Spanish version. The book covers the. Traditional loblolly pine (Pinus taeda) forest management requires infrequent nitrogen (N) and phosphorus (P) applications, preferably two to three times during a 25 to 30 year growth cycle , unlike a switchgrass (Panicum virgatum L.)/pine system, which requires annual N and P fertilizer applications to maximize production .Understanding how drainage water exports N and P after fertilizer.
ORGANIC FERTILIZATION MANAGEMENT INTRODUCTION The nutrient requirements of the crop rotation system are mainly provided by green manure (green fallow land as a first pre-crop). All of the remnants from the pineapples production should be spread over the soil (composting or mulching).

Soil N & P Supply. Stand Age. Relative Amount. From previous work, these data allow water table depth to be transformed into soil water potentials over a landscape. These data are then useful in using SSAND to look at how water table changes may influence nutrient uptake.
Define the uptake characteristics of woody roots of southern pine. Pine plantations usually undergo a final harvest between 25 and 45 years of age, but shorter rotation crops of 15 to 18 years are also considered. Silviculture practices include but are not limited to: site preparation, prescribed burning, tree planting, weed control, fertilization, and thinning (Alig et al., ).

Hydrologic processes on relatively low-gradient poorly drained forested landscapes of the lower coastal plain are usually dominated by shallow water table positions.
Most of the outflows (surface runoff and subsurface drainage) from these watersheds in fact drain from saturated areas where the water is at the surface or a shallow water table is. 1 E X T E N S I ON Institute of Food and Agricultural Sciences Hendry County Extension, P.O.

Of all factors investigated, nutrients and competition were by far the most important in limiting tree and stand growth on a some-what poorly drained flatwoods spodosol.
Aims Our objective was to assess the impacts of water table position and plant functional type on peat struc-ture, plant community composition and aboveground plant production. Methods We initiated a full factorial experiment with 2 water table (WT) treatments (high and low) and 3 plant functional groups (PFG: sedge, Ericaceae, sedge and.

Rainfall is readily absorbed on protected areas and retained by the soils. Runoff during rains is moderate on unprotected areas and the erosion hazard is moderate."

dicity of the fluctuating water table and its effect on the redox environment of the soil, will determine whether these areas are wetlands. The objectives of this study were (i) to evaluate the relationship between water table depth and redox environment for a typical pine flatwoods/cypress swamp landscape and (ii) to use this relationship to contrast the amount of the study area that would.
Net primary production allocation. The two understorey‐eliminated plots had greater needle production than the control plots.
The effect of fertilization (main effect) on branches, needles and total tree net primary production (NPP) was close to statistically significance (P = 009, 007, 006 for branches, needles and tree total, respectively) ().The second watershed was later thinned in July to evaluate the thinning effects on hydrology and water quality.
Both of the treatment watersheds were later fertilized in September to study the effects of fertilization and the water quality of these drained pine plantations through water table above the normal seasonal high water table depth."

With a total water management system these soils are well suited to a variety of flower and vegetable crops.
