G94-1209 Evaluating The Landscape Of A Prospective Home, Don Steinegger, Roch E. Gaussoin Jan 1994

G94-1209 Evaluating The Landscape Of A Prospective Home, Don Steinegger, Roch E. Gaussoin

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses facts to consider when examining a prospective home's yard and landscape.

Often home buyers hire an inspector to evaluate the roof, plumbing, heating system, and structure of a prospective home. Seldom, however, does the landscape receive similar scrutiny.

Buyers should consider investing time and, perhaps, even money in careful evaluation of the landscape they might be purchasing. A healthy, well-designed, well-maintained landscape adds significant equity (15 percent or more) to a property's value. In a climate like Nebraska's, characterized by hot, windy summers and cold, windy winters, lawns, trees, and shrubs play a major role in moderating …


G94-1207 Scab Of Wheat, John E. Watkins, Ben Doupnik, Jr. Jan 1994

G94-1207 Scab Of Wheat, John E. Watkins, Ben Doupnik, Jr.

University of Nebraska-Lincoln Extension: Historical Materials

The identification of and disease cycle of wheat scab is described along with its management. Guidelines for using wheat contaminated with vomitoxin also are included.

Scab or Fusarium head blight is an important disease of wheat, barley, oats, rye and wheatgrasses. Scab manifests itself by the premature death or blighting of spikelets in the wheat head. Direct yield losses are often minor, but can be higher than 50 percent in severely infected fields. The economic significance is magnified by the possibility that the low quality, shriveled grain also can become contaminated by mycotoxins (e.g. vomitoxin, zearalenone).


G94-1185 Fertilizer And Pesticide Containment Guidelines, Larry D. Schulze, Gary Buttermore Jan 1994

G94-1185 Fertilizer And Pesticide Containment Guidelines, Larry D. Schulze, Gary Buttermore

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide summarizes Nebraska regulations on the proper storage of bulk liquid pesticides and fertilizers.

Significant quantities of agricultural chemicals -- both fertilizers and pesticides -- are used annually in Nebraska. Bulk supplies of these chemicals are stored for varying lengths of time by individual producers, chemical dealers, and custom applicators. Spills or potential leakage from storage tanks for liquid fertilizers and pesticides pose a major threat to the integrity of Nebraska's ground and surface water resources. Nebraska has a vital interest in protecting these resources and has made provisions to do so under the Nebraska Environmental Protection Act.


G94-1230 The Foaling Mare, Kathleen P. Anderson Jan 1994

G94-1230 The Foaling Mare, Kathleen P. Anderson

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide outlines the foaling process and appropriate actions to take during both normal and abnormal foaling.

The ultimate goal of any breeding operation should be both maximal foaling and a high survival rate of foals. Most mares will have a normal parturition if left unattended, however, the value of broodmares and their progeny can make leaving parturition to nature an expensive gamble. As the value of mares and foals rise, it becomes more desirable to have someone present during foaling, allowing for immediate assistance to both mare and foal if needed.

Being present when a mare foals can be …


G93-1183 Butterfly Gardening, Dale T. Lindgren, Stephen M. Spomer, Amy Greving Jan 1993

G93-1183 Butterfly Gardening, Dale T. Lindgren, Stephen M. Spomer, Amy Greving

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide outlines planting schemes and arrangements that will help attract butterflies to a garden area.

Butterflies can be found in almost any part of Nebraska, from the Pine Ridge's coniferous forests and across the grasslands of the Sandhills to the deciduous forests along the Missouri River. Watching butterflies, much like bird watching or observing wildflowers has become a popular and enjoyable pastime. Since many natural butterfly habitats have been lost to urbanization and other development, some environmental organizations have incorporated butterfly conservation into their programs. Many people are taking a personal interest in attracting these fascinating insects to their …


G93-1191 Glossary Of Water-Related Terms, William L. Kranz, Delynn Hay, James W. Goeke, David Gosselin Jan 1993

G93-1191 Glossary Of Water-Related Terms, William L. Kranz, Delynn Hay, James W. Goeke, David Gosselin

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide is a glossary of water quantity, quality and human health related terms involving water. Terms are defined in contexts that could affect Nebraskans. We depend upon water for our very existence. The impact of water quality and quantity issues has never been greater. Yet the terminology used to describe the water we drink, the water we provide to plants and animals, the water stored underground, in lakes, rivers, and oceans, is not well understood by many Nebraskans. This listing of water-related terms is intended to reduce the potential for misunderstanding presentations made by elected officials, environmental agencies and …


G93-1157 Testing Irrigation Water, Delynn Hay, K.D. Frank Jan 1993

G93-1157 Testing Irrigation Water, Delynn Hay, K.D. Frank

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains some of the reasons irrigation water should be tested and provides guidelines for collecting and submitting water samples. All irrigation water contains essential plant nutrients. These nutrients are free bonuses from a crop production standpoint. However, some nutrients can be present in amounts that will be toxic or damaging to crop growth. The nutrient content of Nebraska irrigation water can be highly variable from one location to another. The purpose of this guide is to provide guidelines for collecting and submitting irrigation water samples to laboratories for analysis. Reasons for having irrigation water tested are discussed. The …


G93-1150 Rinsing Pesticide Containers, Larry D. Schulze, Clyde Ogg Jan 1993

G93-1150 Rinsing Pesticide Containers, Larry D. Schulze, Clyde Ogg

University of Nebraska-Lincoln Extension: Historical Materials

It is estimated that every year one million plastic agricultural pesticide containers are used in Nebraska. Effective rinsing of these containers saves money, protects the environment and meets federal and state regulations on pesticide use.

Proper rinsing of pesticide containers is easy to do, saves money and helps protect people and the environment. It also helps prevent potential problems with unrinsed containers and storage of the rinse solution (rinsate). Even during a busy season, the few extra minutes it takes to properly rinse empty pesticide containers is time well spent.


G93-1168 Moisture Testing Of Grain, Hay And Silage, Bruce Anderson, Rick Grant Jan 1993

G93-1168 Moisture Testing Of Grain, Hay And Silage, Bruce Anderson, Rick Grant

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide offers methods to help producers test moisture content of grain, hay, silage and other feeds.

Knowing the moisture and dry matter (DM) content of feeds is important to farmers for several reasons:

1. Livestock performance depends on DM consumed; thus, DM content must be known to accurately formulate rations.

2. Knowledge of moisture content is needed for harvest decisions during haying and silage chopping and for safe storage of grains, hay, and silage.

3. Moisture content is a major factor related to the value, or price, of forages and grain.

Every producer should be able to test for …


G93-1180 Horn Fly Control On Cattle, John B. Campbell Jan 1993

G93-1180 Horn Fly Control On Cattle, John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide identifies ways to control horn flies on cattle.

The horn fly is a blood-feeder that feeds 20 to 30 times per day. A population of several thousand horn flies may be present on one animal. When large numbers of these flies are on cattle, the cattle bunch and expend considerable effort fighting the flies. They will often stand in water or seek shade trying to get relief from the flies. When they do this, they fail to graze normally.

Studies in the United States and Canada show that during the grazing season yearling cattle free from horn flies …


G93-1158 Questions And Answers About Atrazine, Fred Roeth, S.D. Comfort Jan 1993

G93-1158 Questions And Answers About Atrazine, Fred Roeth, S.D. Comfort

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide addresses some of the current concerns about atrazine and water quality. Included are some questions and answers about atrazine regarding toxicity, EPA guidelines, presence in water supplies, weed resistance and best management practices. What is atrazine? Atrazine is a herbicide that selectively controls broadleaf (dicot) weeds, such as pigweed, cocklebur, velvetleaf and certain grass weeds in fields of corn and sorghum. Selective control means that the target weeds are controlled, with little or no injury to the crop. Atrazine is well tolerated by actively growing corn and sorghum, which absorb and metabolize the herbicide and thereby detoxify it.

G93-1181 Evaluating Your Landscape Irrigation System, Don Steinegger, Roch E. Gaussoin, Garald L. Horse Jan 1993

G93-1181 Evaluating Your Landscape Irrigation System, Don Steinegger, Roch E. Gaussoin, Garald L. Horse

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide addresses irrigation techniques and methods that can improve water usage.

In the summer months, most water used in residential areas is applied to landscapes. By learning how much water to apply to your landscape and when to apply it, you simultaneously support four landscape irrigation goals: reducing costs, conserving water, reducing non-point pollution (contamination from a broad geographical area such as fertilizer, run off from urban landscapes), and maintaining an attractive landscape.


G93-1153 Stable Fly Control On Cattle, John B. Campbell Jan 1993

G93-1153 Stable Fly Control On Cattle, John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

Control of stable flies in feedlots and dairy operations is covered here.

Description

The stable fly is about the size of a house fly but is dark gray and has dark irregular spots on its abdomen. The proboscis (mouthpart) protrudes bayonet-like in front of the head. The larvae are typical whitish fly maggots. The pupae are chestnut brown and about 1/4 inch long.


G93-1171 Using A Chlorophyll Meter To Improve N Management, Todd A. Peterson, Tracy M. Blackmer, Dennis D. Francis, James S. Schepers Jan 1993

G93-1171 Using A Chlorophyll Meter To Improve N Management, Todd A. Peterson, Tracy M. Blackmer, Dennis D. Francis, James S. Schepers

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes how to use a chlorophyll meter as a tool to improve nitrogen management by detecting nitrogen deficiency and determining the need for additional N fertilizer. Fertilizer nitrogen (N) is increasingly recognized as the source of nitrate contamination in much of Nebraska's groundwater. Improving the efficiency of fertilizer N use reduces the amount of N that can potentially contaminate water resources. Effective management of fertilizer N is a major challenge for grain crop producers. Many factors that affect its efficiency are beyond a producer's control. Weather, equipment limitations and breakdowns, and availability of labor and fertilizer during critical …


G93-1133 Estimating Percent Residue Cover Using The Line-Transect Method, David P. Shelton, Roger Kanable, Paul J. Jasa Jan 1993

G93-1133 Estimating Percent Residue Cover Using The Line-Transect Method, David P. Shelton, Roger Kanable, Paul J. Jasa

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes how to use the line-transect method to estimate the percentage of the soil surface covered with crop residue.

Crop residue left on the soil surface is one of the easiest and most cost-effective methods of reducing soil erosion. Research in Nebraska and other midwestern states has shown that leaving as little as 20 percent of the soil surface covered with crop residues can reduce soil erosion by one-half of what it would be from residue-free conditions. Greater amounts of residue cover will further reduce erosion.


Mp92-64 The Stable Fly: A Pest Of Humans And Domestic Animals, Gustave D. Thomas, Steven R. Skoda Jan 1992

Mp92-64 The Stable Fly: A Pest Of Humans And Domestic Animals, Gustave D. Thomas, Steven R. Skoda

University of Nebraska-Lincoln Extension: Historical Materials

Many species of flies are pests. Many people, if you were to ask them about flies, would be at least vaguely aware of the potential to flies to transmit disease organisms. But yet, for the most part, a fly is a fly is a fly. Sayings like "It must be about to rain, the house flies are biting" are still common and show a general need for more, readily accessible information, particularly about some of the pest flies.

Stable flies, obligate blood-feeders, are very important pests to the cattle industry and, at times, are pests to other groups (they're most …


G92-1094 Controlling External Swine Parasites, John B. Campbell, Barbara Straw Jan 1992

G92-1094 Controlling External Swine Parasites, John B. Campbell, Barbara Straw

University of Nebraska-Lincoln Extension: Historical Materials

Mixing, safety, restrictions, and precautions for insecticides used to control external swine parasites.

Hog Lice and Mange Mites

External parasites of swine include the hog louse and two species of mange mites (the common itch mite and the less common hog follicle mite). Excessive scratching and rubbing by pigs nearly always indicate an infestation of hog lice or mange mites.

Hog lice and mange mites infest a high percentage of swine slaughtered at Midwest slaughter plants.


Ec92-1245 Buffalograss: A Warm-Season Native Grass For Turf, S.A. Deshazer, Terrance P. Riordan, Frederick P. Baxendale, Roch E. Gaussoin Jan 1992

Ec92-1245 Buffalograss: A Warm-Season Native Grass For Turf, S.A. Deshazer, Terrance P. Riordan, Frederick P. Baxendale, Roch E. Gaussoin

University of Nebraska-Lincoln Extension: Historical Materials

Buffalograss is a native grass species which has prospered on the Great Plains for centuries. Both cyclic and prolonged droughts have challenged it to evolve water use efficiency and sod forming ability. People are considering this short, fine-leaved prairie grass for an ecologically sound and energy efficient turf.


G92-1121 Winter Deicing Agents For The Homeowner, Jay Fitzgerald, Donald E. Janssen Jan 1992

G92-1121 Winter Deicing Agents For The Homeowner, Jay Fitzgerald, Donald E. Janssen

University of Nebraska-Lincoln Extension: Historical Materials

Information on deicers and how they affect plants is covered here.

Slick sidewalks and roads are hazardous. Removing compacted snow and ice with shovels or snow blowers is not always an easy task. Deicers can help by "undercutting," or loosening the snow or ice because they lower the freezing point of water.

Do not use deicers to completely melt snow or ice, but to make their removal easier. Deicers melt down through the ice or snow to the hard surface, then spread out underneath. This undercuts and loosens the snow so shoveling and plowing can be done.


G92-1112 Lice Control On Cattle, John B. Campbell Jan 1992

G92-1112 Lice Control On Cattle, John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

Identifying and controlling lice on cattle both are covered here.

Cattle lice may be the most underestimated livestock insect in terms of economic losses. The USDA estimates that U.S. livestock producers lose $125 million a year to cattle lice.

Heavy louse populations cause lowered milk production, loss of flesh, stunted growth, general unthriftiness and anemia. "Chronic" or "carrier" cows may abort due to louse-induced anemia. During severe winters, louse-infested animals are more susceptible to respiratory diseases.


G92-1081 Factors That Affect Soil-Applied Herbicides, R. S. Moomaw, Robert N. Klein, Alex Martin, Fred Roeth, P.J. Shea, G.A. Wicks, R. G. Wilson Jan 1992

G92-1081 Factors That Affect Soil-Applied Herbicides, R. S. Moomaw, Robert N. Klein, Alex Martin, Fred Roeth, P.J. Shea, G.A. Wicks, R. G. Wilson

University of Nebraska-Lincoln Extension: Historical Materials

Characteristics of soil-applied herbicides are discussed, including site of uptake by weeds, solubility, adsorption, persistence, leaching potential, photodecomposition, and volatility. For best performance, preemergence and preplant herbicides must be placed in the top 0 to 3 inches of soil. Placement is important because the herbicide must enter the germinating weed seedling in order to kill it. Herbicides can be blended into the soil by mechanical incorporation, rainfall, or sprinkler irrigation, depending on the herbicide. Herbicide characteristics that determine their performance are site of uptake by weeds, solubility, adsorption, persistence, leaching potential, photodecomposition, and volatility. An understanding of these factors will …


G92-1100 Sugar Beet Nematode, Eric D. Kerr, F.A. Gray, G.D. Franc Jan 1992

G92-1100 Sugar Beet Nematode, Eric D. Kerr, F.A. Gray, G.D. Franc

University of Nebraska-Lincoln Extension: Historical Materials

Symptoms, life cycle and control of sugar beet nematodes are among the topics covered here.

The sugar beet nematode, schachtii, is a major parasite of sugar beets, causing serious stand and yield reductions. It was first identified in 1859 on sugar beets near Halle, Germany. It was first observed in the United States as early as 1895 and was reported in two fields near Gering, Nebraska in 1926.


G92-1103 White Mold Of Dry Beans, James R. Steadman, Howard F. Schwartz, Eric D. Kerr Jan 1992

G92-1103 White Mold Of Dry Beans, James R. Steadman, Howard F. Schwartz, Eric D. Kerr

University of Nebraska-Lincoln Extension: Historical Materials

White mold symptoms, infection and control are covered here.

One of the most important diseases affecting dry beans in western Nebraska and Colorado is white mold caused by the fungus Sclerotinia sclerotiorum. In a recent year, losses from this disease averaged as high as 20 percent, with a few individual field losses exceeding 65 percent.


G92-1119 Rust Diseases Of Turfgrass, John E. Watkins, Roch E. Gaussoin Jan 1992

G92-1119 Rust Diseases Of Turfgrass, John E. Watkins, Roch E. Gaussoin

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes the various rust diseases common to Nebraska and offers suggestions for maintaining a vigorous and disease-resistant lawn.

Rust diseases occur on all turfgrasses; however, most rust problems occur on Kentucky bluegrass, perennial ryegrass, tall fescue and zoysia. In the cool-temperate regions of North America, cool season turfgrasses may suffer severe injury late in summer by attack from one of the rust pathogens. In addition, rust-weakened plants are much more susceptible to injury from environmental stresses and to attack by other turfgrass pathogens.


G92-1096 Understand Your Soil Test: Ph-Excess Lime-Lime Needs, K.D. Frank, Delno Knudsen Jan 1992

G92-1096 Understand Your Soil Test: Ph-Excess Lime-Lime Needs, K.D. Frank, Delno Knudsen

University of Nebraska-Lincoln Extension: Historical Materials

The relationships among pH, soil type, and lime requirements are explained.

Accurate soil tests can be an excellent management tool. Misuse of soil tests leads to increased production costs, yield losses, or both. The elements required by plants for proper growth have been determined by experimentation. Experience has shown that soils across Nebraska differ greatly in their capacity to supply these elements. The amount of each element supplied by a soil depends on several factors. Two important ones are: (1) the type of material from which the soil was formed, and (2) the treatment the soil has received since being …


Ec92-125 On-Farm Trials For Farmers Using The Randomized Complete Block Design, Phil Rzewnicki Jan 1992

Ec92-125 On-Farm Trials For Farmers Using The Randomized Complete Block Design, Phil Rzewnicki

University of Nebraska-Lincoln Extension: Historical Materials

Farmers are interested in evaluating new agricultural practices on their own farms. To produce results credible to themselves, other farmers, and researchers, a systematic method of testing should be used. If a comparison of agricultural practices results in one practice yielding a few more bushels of crop than another, this does not necessarily mean it is a more valuable practice. The difference may simply be due to field variation or chance.

This circular discusses the on-farm trials and incorporation of the two basic requirements in designing experiments: randomization and replication.


A Thematic Unit For Integrating Social Studies And Science In The First Grade, Lin Marjorie Lasater Jan 1992

A Thematic Unit For Integrating Social Studies And Science In The First Grade, Lin Marjorie Lasater

All Graduate Projects

A thematic unit for integrating social studies and science with other curriculum areas was developed for first grade students. The theme for the unit centered around farms. The unit was divided into five subunits: farms, farm animals, orchards/vineyards (to include fruits of the Yakima Valley and apples), crops (to include vegetables of the Yakima Valley, pumpkins, and wheat), and nutrition/four food groups. The literature was reviewed to establish a theoretical foundation for the unit and for activities that focused on reading, writing, and language development.
