Economic Impact Of Ethanol Production On Arkansas Cattle Feed Prices, Mary Leigh Clayton

Student Theses and Dissertations

The purpose of this study is to determine what the impact of the increase in ethanol production is having on Arkansas cattle feed prices. This study relies on secondary data from Arkansas and national agricultural sectors. Both descriptive and analytical methods are used to evaluate the impact of crude oil, ethanol, and beef cattle prices on cattle feed. Data was collected from the USDA- NASS for beef cattle prices, EIA for crude oil, the Official Nebraska Government Website for ethanol, and the ERS/USDA Feedgrains Database for corn meal. The analytical methods for this study are graphical, correlation, and regression analysis. …

Are Biotechnology And Sustainable Agriculture Compatible?, David E. Ervin, Leland L. Glenna, Raymond Adelard Jussaume

Economics Faculty Publications and Presentations

Agricultural biotechnology has been largely opposed by advocates in the sustainable agriculture movement, despite claims by the technology’s proponents that it holds the promise to deliver both production (economic) and environmental benefits, two legs of the sustainability stool. We argue in this paper that participants in this polarized debate are talking past each other because assumptions about biotechnology and sustainability remain simplistic and poorly defined. Genetically engineered (GE) herbicide-resistant and insect-resistant crop varieties are the most visible current forms of agricultural biotechnology, and thus the form of biotechnology that many in the sustainability movement react to. However, these crops represent …

A Comprehensive Index For Assessing Environmental Stress In Animals, Terry L. Mader, Leslie J. Johnson, John B. Gaghan Dr

Nebraska Cooperative Extension: Faculty and Staff Publications

Numerous models and indices exist that attempt to characterize the effect of environmental factors on the comfort of animals and humans. Heat and cold indices have been utilized to adjust ambient temperature (Ta) for the effects of relative humidity (RH) or wind speed (WS) or both for the purposes of obtaining a “feels-like” or apparent temperature. However, no model has been found that incorporates adjustments for RH, WS, and radiation (RAD) over conditions that encompass hot and cold environmental conditions. The objective of this study was to develop a comprehensive climate index (CCI) that has application under a wide range …

Good Agricultural Practices For Food Safety Of Fresh Produce, Laurie Hodges

Department of Agronomy and Horticulture: Faculty Publications

What are the guiding principles of food safety for fresh produce?

• Once contaminated, removing or killing pathogens on produce is very difficult.

• Preventing microbial contamination at all steps, from production to distribution, is strongly favored over treatments to eliminate contamination that may have occurred.

• Document the implementation of prevention programs, and educate workers at all levels of the agricultural and packing environments on food safety.

Key Signatures of a Credible Food Safety Program

The following is a condensed checklist of practices and conditions that reduce the potential for fresh produce to be exposed to pathogenic microbes. Review …

Nutrient Content Of Utah Turkey Litter, David D. Frame, Gary L. Anderson

All Current Publications

An estimated 60,000 cubic yards (24,700 tons) of turkey growout litter is produced annually in Utah. Most is destined for land application on commercial cropland or pastureland.

Biosecurity Principles: Protecting Your Investment, David D. Frame

All Current Publications

Although the magnitude of economic value is usually much less in small standard-bred poultry operations compared to multimillion-dollar commercial chicken or turkey companies, there are still many reasons to protect your investment. Value is not always measured in simple dollar terms.

Modeling Methane Emission From Wetlands In North-Eastern New South Wales, Australia Using Landsat Etm+, Clement E. Akumu, Sumith Pathirana, Serwan Baban, Daniel Bucher

Agricultural and Environmental Sciences Faculty Research

Natural wetlands constitute a major source of methane emission to the atmosphere, accounting for approximately 32 ± 9.4% of the total methane emission. Estimation of methane emission from wetlands at both local and national scale using process-based models would improve our understanding of their contribution to global methane emission. The aim of the study is to estimate the amount of methane emission from the coastal wetlands in north-eastern New South Wales (NSW), Australia, using Landsat ETM+ and to estimate emission with a temperature increase. Supervised wetland classification was performed using the Maximum Likelihood Standard algorithm. The temperature dependent factor was …

The Economic Importance Of Draught Oxen On Small Farms In Namibia's Eastern Caprivi Region, Andrew B. Conroy, Mogos Yakob Teweldmehidin

Natural Resources & the Environment

The main aim of this study was to analyse and document the value of smallholder farmers’ use of Draught Animal Power (DAP) systems in the Eastern Caprivi Region and to test the economic viability of DAP usage versus using tractors. This study applied Rapid Rural Appraisal techniques (RRA), including a survey. Semi-structured interviews were conducted with 312 farmers at their farms and data was gathered on the use of and economics related to the draught animal power system. Crop enterprise budgets, project reports, expert opinions and group discussions were analysed. The research found that the use of animal power performs …

Urban Farm: Naturally Grown Local Food, Stephanie Shepard

Interior Design Program: Terminal Projects

There are many things to be said for the benefits of urban farming. From feeding the hungry, to providing an educational experience for a community that otherwise has no agricultural knowledge, to reducing heat island effect, the gain is almost immeasurable.

According to the United States Census Bureau, 35.9 million people live below the poverty line in America. Requests for emergency food assistance has increased by an average of 14% a year since 2004 and about 20% of those requests generally go unmet. In addition, national food banks report that 23.3 million people turned to their services in 2009, an …

A Discounted Cash Flow Method Of Valuation For Single Trees And Urban Forests, Kristin Heffelfinger

All Theses

Urban foresters need a consistent method for valuing single trees with specific non-timber values. There are several accepted methods to accomplish this; comparison of results across the methods ensures consistency. Discounted cash flow analysis (DCF) is one of these methods, but many appraisers or others valuing urban tree are reluctant to use it because it requires complex calculations and assumptions. However, DCF has the advantage of accounting for the time value of money and certain intangible benefits presented by urban trees. Current models are adapted to specific locations and species; a general method for urban tree valuation has not been …

Residual Feed Intake As A Selection Tool, Jessica Crozier, D. R. Zobell

Grapevine And Soil Water Relations With Nodding Needlegrass (Nassella Cernua), A California Native Grass, As A Cover Crop, Michael J. Costello

Wine and Viticulture

Nodding needlegrass [Nassella cernua (Stebbins & R.M. Love) Barkworth], a California native perennial grass, was tested for its effects on grapevine and soil–water relations in a drip-irrigated vineyard in Parlier, CA. Vine water status and in-row and between-row soil moisture (at 0.3 m, 0.6 m, 0.9 m, 1.2 m, and 1.5 m) were monitored semiweekly from June to September. There was no overall significant difference in leaf water potential between treatments. In-row soil moisture was lowest at depths of 0.6 m to 0.9 m within the nodding needlegrass treatment but was lowest from 0.3 m to 0.9 m within the …
