- Fertilizing Pine Plantations
-
Fertilization of pine plantations in the South has increased dramatically with over 1,000,000 acres fertilized in 1997 alone. 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.
- Border Irrigation System
-
Border irrigation is an old irrigation system used in the western part of the United States to irrigate alfalfa, wheat, other small grains, and sometimes row crops. It is a system where a large volume of water is put in a defined border or bay at the top of the field and guided by the borders down the slope in a uniform wetting pattern to the end of the field.
- Urban Integrated Pest Management
-
People are becoming more aware of and concerned about the effects of chemicals on our environment. The impact of the use of pesticides on drinking water and food production, as well as the impact in homes and landscapes has become a significant social concern. Many people have begun to wonder if there are ways to reduce or eliminate pesticide use in non-agricultural settings.
- Before You Order Tree Seedlings
-
Good tree planting practices include good planting stock, a well-selected and properly prepared site, proper planting methods, and adequate protection and care of the tree seedlings before and after planting. Failure in any of these planting practices often results in unsatisfactory survival or growth or even in complete failure. This article provides a few questions that should be asked before ordering seedlings.

Added: November 05, 2008The health and structure of trees are reflections of soil health. The ecological processes which govern tree survival and growth are concentrated around the soil/root interface. As soils, and associated resources change, tree systems must change to effectively utilize and tolerate changing resources quantities and qualities, as well as the physical space available. Soil compaction is a major tree-limiting feature of community forest managers and arborists.

Added: October 31, 2008The strength of tree stems to resist bending in the wind is associated with the cross-sectional area of the stem. Strength is proportional to the diameter of the stem to the fourth power (DIAMETER). Small increases in diameter yield large increases in strength. This publication presents a theoretical examination of relative strengths of round stems as modeled by bending moments in solid cylinders. Resistance to torsional forces (twist) are two times that of bending forces.
- Your Florida Dooryard Citrus Guide - Pruning
-
Although large machines prune closely planted trees in commercial citrus groves on a regular basis, dooryard citrus need not be pruned at all. There are exceptions: aesthetic purposes, to prevent shading of other plants, to prevent soilborne diseases, to remove cold-damaged limbs, and to rejuvenate old trees with reduced vigor, twig and small branch dieback, and small fruit.
- Drying Softwoods for Value Added Markets
-
There is a great opportunity for softwood mills to enter into the value added markets arena, including lumber used for moulding, doors, windows, and furniture. However, to be successful in this market, quality drying is a prerequisite. In this paper, suggestions on how to select a proper target moisture content, conventional temperature schedules for quality drying, equalizing for a uniform final moisture content, and conditioning for stress relief will be discussed.
- Urban Forestry
-
What is an urban forest? It is all of the trees and other vegetation in and around a town, village or city. Traditionally it has referred to tree-lined streets, but an urban forest also includes trees in home landscapes, schoolyards, parks, riverbanks, cemeteries, utility rights-of-way, adjacent woodlands and anywhere else trees can grow.
- Tax Tips for Forest Landowners for the 1997 Tax Year
-
The long term capital gains rate has been reduced significantly--if you sold your timber at the right time and you met the correct holding period requirements. These new rules, plus the information that follows, are some things to keep in mind.
- Selecting Landscape Plants: Shade Trees
-
Trees are the basic element for any landscape plan. They set the stage for the entire home grounds design. The type used and their location determine to a great extent what other plantings are appropriate.

- Measuring Standing Trees
-
Woodland owners often need to measure the merchantable board foot content (termed "volume") of certain trees in their woodland. This publication teaches you how.
- Hawksbill Turtle (Eretmochlys imbricata)
-
The hawksbill turtle's shell is covered with glossy brown and tan overlapping scutes, or horny plates. It reaches 2 feet (65 cm) long and weighs an average of 90 pounds (40 kg). The scales of the hawksbill were once used to make combs and curious.
- Florida Torreya (Torreya taxifolia)

Consideration of how to meet human needs for materials and still maintain or enhance other needs of the forest is vital. Forests cannot be isolated from human influence or from human needs.
- Create A Certified Wildlife Habitat
-
Go out in your backyard and look around! Watch the butterflies and hummingbirds dance in search of nectar. Listen to the trill of songbirds. Hear the plop of a frog jumping into a pond. This isn't your yard, you say? It could be. It's not hard, and it doesn't matter where you live or how much space you have.

Added: November 05, 2008Soil compaction is a complex set of physical, chemical, and biological constraints on tree growth. Principle components leading to limited growth are the loss of aeration pore space, poor gas exchange with the atmosphere, lack of tree available water, and mechanical impedance of root growth. There are significant genetic differences between tree species for tolerating various levels of soil compaction.
- Managing Trees and Turfgrasses
-
Trees and turfgrasses commonly share the same landscape. Both require space, light, water, air, essential nutrients, and the appropriate temperature for growth, but there is often a stuggle to maintian quality turf under healthy trees.
- Tree Heights & Force of Fall
-
Trees represent large amounts of potential energy standing above the ground. When trees fall, the force with which they hit the ground surface is proportional to their height to the fifth power.
