Pb1637 Fertilizers And Their Use, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

An understanding of soil chemical properties is important because of their effect on nutrient availability to plants. Also, these properties may usually be favorably altered with the use of lime and/or fertilizer materials. Many plants need 18 elements (see Table 1) for normal growth and completion of their life cycle. These elements are called the essential plant nutrients. Soil amendments containing the essential plant nutrients or having the effect of favorably changing the soil chemistry have been developed and used to enhance plant nutrition. These amendments are our lime and fertilizer materials.

With the development of these modern lime and …

Sp546 Diseases Of Shade And Ornamental Trees, The University Of Tennessee Agricultural Extension Service

Forestry, Trees, and Timber

Sp548 Fertilizing Landscape Trees, The University Of Tennessee Agricultural Extension Service

Forestry, Trees, and Timber

Trees in residential and commercial landscape plantings are often fertilized to keep them healthy and attractive. Over-fertilization is common, causing excessive growth, especially on young nursery stock. Trees growing in lawn areas usually receive some nutrients when the turfgrass is fertilized. This is usually sufficient to maintain most trees in fertile soil. However, fertilization may be needed on altered soils where unconsolidated fill material has been added or the topsoil has been removed. Managed urban areas where fallen leaves are removed may also require a fertilization regime to enrich soil and replenish nutrients.

Fertilizer (plant nutrition) is no substitute for …

Sp307-O-Home Apple Cider Production, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

Cider making is an art that is as old as apple production itself. When properly made, fresh apple cider is a safe, natural, delicious product that conjures up images of autumn and the country.

Apple cider is simply the liquid that is released when apples are crushed. It has nothing added and nothing taken away from it. Apple cider will be cloudy due to the presence of suspended apple solids. Since apple cider contains no preservatives, it has a limited shelf life, and special attention must be paid to proper storage. The terms apple cider and apple juice are often …

Pb819 Growing Vegetable Transplants In Tennessee, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

The production of vegetable plants for commercial and home use is increasing in Tennessee. This is partially due to the expansion of greenhouse flower and ornamental production. To meet the demand for home gardeners, growers have gradually added vegetable plants to their spring production operation. Growers are finding that production of quality plants is a profitable business in urban areas.

Successful vegetable plant production is not a simple practice, because it requires technical knowledge of production practices within an enclosed environment, careful planning and man age ment. Combining the required environmental conditions favorable for vegetable plant growth, either in a …

Capture And On-Site Release Of Nuisance Black Bears And Survival Of Orphaned Black Bears Released In The Great Smoky Mountains, Jay Edwin Clark

Masters Theses

Since the establishment of Great Smoky Mountains National Park (GSMNP) in 1934, interactions between black bears (Ursus americanus) and visitors have been a regular occurrence. Prior to 1990, capture and relocation was the primary management alternative for nuisance bears in GSMNP. Since 1990, wildlife biologists in GSMNP have used capture and on-site release as an aversive conditioning technique for nuisance black bears. This technique involves capturing and immobilizing bears that frequent developed areas, collecting biological data, and releasing the bears back into the same area. The premise of this technique is to reinforce the natural fear of humans and thereby …

Maternal Employment And Dietary Quality Of Children Aged 42-60 Months, Lynn A. Samson

Masters Theses

(From the Summary): Abbreviated Maternal employment is becoming more the usual than an exception. Employment can be beneficial for mothers, providing satisfaction and increasing self-esteem. On the other hand, it can be stressful juggling between the roles of employee and mother. Other family members might help ease some of the burden, but mothers still bear most of the responsibility of child care and household responsibilities. Working mothers have less time to spend on food and nutrition. In most cases, the diets of children whose mothers are employed do not differ from children of mothers who are not employed, …

Pb962 Producing Cantaloupes In Tennessee, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

Cantaloupes are a warm-season crop that requires 70 to 90 days, depending upon the variety, from seeding to marketable fruit. Their consumption has increased by 11 percent since 1958. Almost all of the increase in consumption can be credited to the installation of salad bars in fast-food restaurants. Cantaloupes are very sensitive to cool temperatures. If they are exposed to cool temperatures (50 degrees or less) for short periods of time during the growing period, growth will be severely stunted. Plants will continue to survive, but their growth rate and fruit set rate per plant decreases. About 700 acres of …

Home Garden, Lawn, and Landscape

Brown rot, caused by the fungus Monilinia fructicola, is the most common and destructive disease of stone fruits in Tennessee. Brown rot occurs on peaches, plums, nectarines, cherries and apricots. This disease reduces yields primarily by rotting the fruit both on the tree and after harvest. Brown rot can potentially cause complete crop loss in unsprayed orchards when environmental condi tions are favorable for disease development.

Pb1626-Ornamental Grasses In The Landscape, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

Ornamental grasses add texture, contrast, color and year-round interest to the landscape. Just like other groups of landscape plants, ornamental grasses are a diverse group that expand the plant palette of designers. They come in a range of sizes from the dwarf hakone grass to the giant ravenna grass. There are golden or white variegated cultivars. Some provide shades of silver and blue. Others are tinged red. Grasses that emerge late in the spring can fill voids left by spring-flowering bulbs and early spring perennials. The seed-heads or plumes of late-season grasses add ornamental value that persists into the winter. …

Pb1628 Forest Products Measurements And Values, The University Of Tennessee Agricultural Extension Service

Forestry, Trees, and Timber

Success in buying and selling forest products depends on one’s knowledge of product measurement and ability to predict the current market value. When trees are harvested, they can be sold as whole trees, factory class sawlogs, construction class sawlogs, veneer logs, pulpwood and/or chipwood. Lumber is sold by its grade, which is determined by the size and location of defects. Each product from the forest has a particular method by which it is measured and its market value estimated. This publication explains common forest products measures used in Tennessee and how to estimate the current market value.

Sp503-D-An Introduction To Integrated Pest Management Of Landscapes, The University Of Tennessee Agricultural Extension Service

Insects, Pests, Plant Diseases and Weeds

A properly maintained landscape adds beauty and value to a property. Landscapes often contain a great diversity of plants and so have the potential to attract many pests. Fortunately, natural enemies of pests often regulate pest populations to low or moderate levels and chemical control is not needed. However, pests may still cause more damage than can be tolerated. We recommend using an integrated approach to managing pests.

This factsheet was written to familiarize the home or professional landscaper with the steps to using integrated pest management (IPM) in the landscape. Using this approach, you can manage damaging pests without …

Sp277-S Black Root Rot Of Tobacco, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

Black root rot has been one of the most costly diseases of tobacco in Tennessee. This disease attacks tobacco either in the plant bed or in the field. It is a serious problem where tobacco is grown repeatedly in the same bed or field. Rarely does black root rot cause spectacular damage in any one field. It is important that growers be able to recognize black root rot and take the necessary control measures.

Sp341-L-Nematode Control In The Home Garden, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

Plant-parasitic nematodes are slender, worm-like animals that usually can be seen only with the aid of a microscope. There are thousands of different kinds of nematodes, but few are pests in vegetable gardens of Tennessee. The southern root-knot nematode is the most serious pest in the home garden, although lesion and lance nematodes occasionally can cause damage.

Pb1038 Fertilization & Management, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

Fertilization and liming practices based upon a soil test help ensure the most cost efficient and environmentally sound development and maintenance of lawns. A soil test is especially critical when soils test low in pH, phosphorus or potassium. A properly fertilized and limed lawn is usually greener, more vigorous, less weedy and more attractive than a poorly fertilized lawn or one suffering from the effects of low soil pH (soil pH is a measure of the soil’s acid content).

The primary nutrients (nitrogen, phosphorus and potassium) must be added to most lawns, since soils in Tennessee seldom furnish adequate supplies. …

Pb1623-Decision Making Handbook For Insect & Mite Pests Of Ornamental Plants, The University Of Tennessee Agricultural Extension Service

Insects, Pests, Plant Diseases and Weeds

Attractive, vital landscape plants contribute significantly to real estate values. On the other hand, poorly maintained landscapes may become a liability, especially if trees or their parts fall and cause property or bodily injury. This realization, coupled with increased leisure time to enjoy our yards and more discretionary income for landscaping and landscape maintenance, has contributed to dramatic increases in the demand for nursery products and competent service personnel. At the same time, concerns for environmental quality and safe use of pesticides require that plant health care activities, including pest control, provide quality plants without creating adverse side effects. This …

Data were collected during portions of 2 years beginning in January 1994, and ending in March 1996. The major objectives of the study were to evaluate the effects relocated wild bobwhites might have on an existing resident quail population, and to determine the feasibility of relocating quail wild quail as a potential management tool. Study objectives were accomplished by obtaining data necessary to compare …

Land-Use And Other Factors Affecting The Distribution Of Aquatic Macroinvertebrates In The Richland Creek Watershed On Walden Ridge In Tennessee, Jack Thomas Pickett

Masters Theses

In this study aquatic invertebrates were sampled in riffle habitats of the 4 branches of Richland Creek on Walden Ridge, Tennessee (1800 feet elevation). The 4 branches have low-gradient upper portions on the ridge top and high-gradient lower portions in the canyons that descend the ridge. Pine plantations (pinus taeda) cover about 33% of the watershed, with the coverage of the 4 branch creeks varying from 6% to 90%. The pH and total alkalinity of the 4 branch creeks were found to be inversely correlated with the amount of pine plantation coverage of the watersheds of the creeks, …

Sp435-C No-Till Establishment Of Forage Crops, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

Agriculture has changed in many ways during the last 50 years. One of the greatest changes has been the use of no-till planting methods. When no-till planting is mentioned, most people usually think of crops such as corn, soybeans and cotton. The problem of soil erosion with conventional row-crop production has been significantly decreased by using herbicides to kill a cover crop and planting without tillage. Though often overlooked, no-till technology is also well-suited to be used in forage crop establishment.
