Valuing Risk Tradeoffs And Voluntary Insect Reduction, Luanne Lohr, Timothy Park, Leon Higley

Department of Entomology: Faculty Publications

Farmers’ willingness to voluntarily reduce insecticide use is not considered when regulatory approaches to environmental protection are proposed. Regulations that require behavior that would voluntarily be undertaken are excessive and economically inefficient. Using survey data from a contingent valuation scenario, we demonstrate the willingness of crop producers in four Midwestern states in the U.S. to trade yield losses for environmental risk reduction by eliminating an insecticide application. The mean acceptable yield loss for a sample of 1,138 producers in Illinois, Iowa, Nebraska, and Ohio is $8.25 per acre. Acceptable yield loss increases with the rated importance of environmental goods (fish, …

Ec96-1770 Windbreaks For Snow Management, James R. Brandle, H. Doak Nickerson

University of Nebraska-Lincoln Extension: Historical Materials

In areas of high winds and blowing snow, windbreaks can reduce the amount of effort spent on snow management. They can be designed to spread snow across a large area or to confine it to a relatively small storage area. The design of your windbreak will depend on your objective. Field windbreaks designed to distribute snow evenly across a field should be tall and porous. In contrast, windbreaks designed to capture snow and control drifting should have multiple rows with high density. There is no one set design, number of rows, or width of planting that is ideal for every …

Precision farming is a term applied to a broad array of topics that relate to the precise management of small units of land in contrast to the more traditional management of an entire field in a uniform manner.

G96-1305 Water Runoff From Sprinkler Irrigation: A Case Study, Norman L. Klocke, William L. Kranz, C. Dean Yonts, Kelly Wertz

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide illustrates the influence of soil texture, topography and irrigation system characteristics on potential runoff.

When water is applied to a field through a sprinkler irrigation system, it should soak into the soil where it lands rather than drain to a low spot or off the field altogether. Runoff causes non-uniformity of water application, poor irrigation efficiency and possible leaching of chemicals to the groundwater. Some systems like LEPA (Low Energy Precision Application) are designed so water does not immediately soak into the soil. However, proper LEPA designs also call for tillage practices that hold the water on the …

G96-1293 Feedlot Abandonment Recommended Procedures, Richard K. Koelsch, Gerald R. Bodman

University of Nebraska-Lincoln Extension: Historical Materials

An abandoned animal feeding facility is a significant threat to the environment. Procedures to minimize the risk are discussed.

Feedlot abandonment occurs for various reasons, including economic and social changes, environmental concerns, consolidation for more cost effective management and operation, and modification of personal goals. Whether a feedlot is abandoned for a short time until some crisis passes, or permanently, steps are necessary to minimize the risk of environmental degradation.

Under both scenarios, an abandoned feedlot poses an immediate threat to surface and groundwater quality. The unused facility is also a potential nuisance and source of health problems for humans …

G96-1311 Global Warming: What Is Known And Why Nebraska Agriculture Should Care, William E. Easterling, Cynthia Hayes

University of Nebraska-Lincoln Extension: Historical Materials

The purpose of this NebGuide is to review the facts of global warming, to point out what is sheer speculation, and to suggest why Nebraska agriculture should care about global warming.

Climatologists talk about global warming one year and the next year they talk about global cooling! Depending on the time periods involved, both views may be correct. Over the next few hundred years, the earth may undergo a general cooling trend. This trend is consistent with the regular shifts into and out of ice age conditions that have characterized the earth's climate history of the last 50,000 years. However, …

Ec96-143 Pesticide Runoff And Water Quality In Nebraska, Steven Comfort, Thomas G. Franti, S.K. Smith

University of Nebraska-Lincoln Extension: Historical Materials

Nebraska's natural resources provide its residents with an abundance of wildlife, recreation, and agricultural opportunities. Some of the state's most important resources are its lakes, rivers and streams. These surface waters provide year-round habitat for aquatic and terrestrial wildlife, rest stops for migratory birds, and countless hours of enjoyment for outdoor enthusiasts. In addition, surface waters provide a source of drinking water for many Nebraska residents, and are vital for some farming and industrial operations. To better understand how surface waters become contaminated from pesticide runoff, the various factors and processes influencing runoff must be understood. With this understanding, pesticide …

Potential For Crop Residue To Restrict Herbicide Movement In Surface From Water Corn And Soybean Fields, William W. Witt

KWRRI Research Reports

As no-tillage and other conservation tillage practices continue to increase, it is important to have knowledge of herbicide adsorption on crop residue with regard to the potential for the herbicide to be removed from the residue and move with runoff water from the field into nearby surface waters. Previous research had compared herbicide adsorption to various residues, but it was difficult to make comparisons among these studies because the residues were from different crops or the amount of residue decomposition was different. The amount of "weathering" or "aging" of the residue at the time of herbicide treatment could alter the …

Endangered Species And Irrigated Agriculture, Water Resource Competition In Western River Systems, United States Department Of Agriculture, Economic Research Service

Agriculture

This report characterizes several aspects of water allocation tradeoffs between fish species listed under the Federal Endangered Species Act and agriculture in the American West. The geographic intersection between endangered/threatened (E/T) fish and agricultural production reliant on surface water for irrigation is identified. Three findings are: (1) 235 counties, representing 22 percent of the West's counties, contain irrigated production that relies on water from rivers with E/T fish, (2) areas generating the highest revenues per acre from crop production are those most dependent on surface water irrigation, and (3) these same areas are also most likely to be drawing water …

Ec95-817 Nebraska Agricultural Producers Preferences For National Agriculture, And Food Policy After 1995, A.L. (Roy) Frederick, Glenn A. Helmers, Steven L. Elmore

University of Nebraska-Lincoln Extension: Historical Materials

Farmers' preferences are important in the development of farm bills. In that spirit, the Department of Agricultural Economics at the University of Nebraska-Lincoln and the Nebraska Agricultural Statistics Service recently asked a random sample of agricultural producers about their preferences for the 1995 farm bill. Similar surveys were undertaken in 1984 and 1989, prior to the last two farm bills. Each Nebraska survey was part of a larger, national effort. This year, 15 states, scattered across all regions of the United States, participated.

The purpose of this report is to summarize Nebraska producers' views on key issues likely to be …

Also, in situations where “gray areas” existed, these industry …

G95-1236 Developing Beef Quality Assurance, Dicky D. Griffin, Louis Perino, Don Hudson

University of Nebraska-Lincoln Extension: Historical Materials

This Neb-Guide gives guidelines for developing a feedlot beef quality assurance program.

The displacement of people from agriculture into other areas of employment has broken the relationship between most consumers and producers. The consumer's lack of knowledge about agricultural production coupled with concern for misuse of technological advances in agriculture has created great concern for the safety of their food supply. Consumers are worried that their food will be contaminated by antibiotics, hormones, and agricultural chemicals. Recently, bacterial contamination of beef has been added to their fears. These concerns, combined with diet and health concerns for eating red meat and …

Ec95-1560 Use Of Cultural Practices In Crop Insect Pest Management, Robert J. Wright

University of Nebraska-Lincoln Extension: Historical Materials

This Extension Circular reviews what is known about the effects of rotations, tillage practices, and planting and harvest dates on crop insect management, focusing on major crops in Nebraska.

Before the development of synthetic organic insecticides (pre-DDT era), rotations, tillage practices, planting and harvest dates, and other nonchemical cultural controls were commonly recommended for insect management. Research focused on crop rotation and other cultural practices for insect management. With the development of DDT and later insecticides however, research on nonchemical controls decreased markedly.

With the emergence of the concept of sustainable agriculture in the 1980s, there has been increased emphasis …

S. sclerotiorum has caused a disease known as white mold on dry edible beans in western Nebraska for 40 years, but it did not become a problem in soybeans until the 1990s. This fungal pathogen can be found on soybeans in Illinois, Iowa, Michigan, Ohio, Minnesota, Wisconsin, and North Dakota. …

G95-1267 Manure Applicator Calibration, Richard K. Koelsch

University of Nebraska-Lincoln Extension: Historical Materials

Calibration methods for manure spreaders are discussed here.

Applying manure to land often is considered a waste disposal process rather than a fertilization process. Applying manure as a waste product is causing growing concerns about groundwater and surface water contamiantion. Increasing commercial fertilizer costs and regulatory mandates will encourage application of manure as a nutrient source in the future.
