Cover Crop Effect On Subsequent Wheat Yield In The Central Great Plains, David Nielsen, Drew Lyon, Robert Higgins, Gary Hergert, Johnathon Holman, Merle Vigil 2016 Washington State University

Cover Crop Effect On Subsequent Wheat Yield In The Central Great Plains, David Nielsen, Drew Lyon, Robert Higgins, Gary Hergert, Johnathon Holman, Merle Vigil

David C. Nielsen

Crop production systems in the water-limited environment of the semiarid central Great Plains may not have potential to profitably use cover crops because of lowered subsequent wheat (Triticum asestivum L.) yields following the cover crop. Mixtures have reportedly shown less yield-reducing effects on subsequent crops than single-species plantings. This study was conducted to determine winter wheat yields following both mixtures and single-species plantings of spring-planted cover crops. The study was conducted at Akron, CO, and Sidney, NE, during the 2012–2013 and 2013–2014 wheat growing seasons under both rainfed and irrigated conditions. Precipitation storage efficiency before wheat planting, wheat ...

Evaluating Approaches To Measuring Ocular Pain In Bovine Calves With Corneal Scarification And Ibk-Associated Corneal Ulcerations, Reneé Dewell, Suzanne T. Millman, Stacie A. Gould, Kyle L. Tofflemire, R. David Whitley, Rebecca L. Parsons, Eric W. Lowe, Fangfang Liu, Chong Wang, Annette O'Connor

Chong Wang

The objective of this experiment was to describe the magnitude and variation of measures of ocular pain in cattle experiencing corneal scarification and corneal ulcerations associated with experimentally induced IBK. In our study, pressure algometry may be appropriate to quantify ocular pain in calves. This information will enable appropriate design of studies for assessing the extent of ocular pain associated with ophthalmic abnormalities in cattle and efficacy of pain mitigation strategies.

Latencies, durations and occurrence of behavior and physiologic changes were observed using direct observationand video ...


Behavioral Determinants Of Biofortified Food Acceptance: The Case Of Orange-Fleshed Sweet Potato In Ghana, Chinonso E. Etumnu 2016 University of San Francisco

Behavioral Determinants Of Biofortified Food Acceptance: The Case Of Orange-Fleshed Sweet Potato In Ghana, Chinonso E. Etumnu

Master's Theses

Biofortified foods are being introduced in sub-Saharan Africa as an important strategy to help address micronutrient malnutrition. However, there has been little research on factors that could play decisive roles in their successful introduction. This paper investigates the determinants of consumer acceptance of biofortified orange-fleshed sweet potato (OFSP) using data from a choice experiment conducted in Ghana. I find that OFSP is preferred to traditional white-fleshed and yellow-fleshed sweet potatoes as indicated by consumers' marginal willingness to pay for the three varieties. I also find that respondents' socio-economic characteristics do not have a significant effect on consumer acceptance of OFSP ...

The proposal is to integrate agriculture as a design tool to reconnect to the city’s agricultural past and as a model for cities of the future. First, I discuss Chula Vista’s history and contemporary context, including demographics. I review the existing urban agriculture policies Chula Vista has and compare them to other cities in California. The second part of the project is concerned with how to choose and develop a ...


Evaluating Soil Tillage Practices Using X-Ray Computed Tomography And Conventional Laboratory Methods, Maria Ambert-Sanchez, Steven K. Mickelson, Syed I. Ahmed, Joseph N. Gray, David F. Webber 2016 Peace Corps

Evaluating Soil Tillage Practices Using X-Ray Computed Tomography And Conventional Laboratory Methods, Maria Ambert-Sanchez, Steven K. Mickelson, Syed I. Ahmed, Joseph N. Gray, David F. Webber

Steven K. Mickelson

Using x-ray computed tomography (CT) for non-destructive 3-D imaging and analysis of soil physical properties has been investigated for over 30 years. However, applying this system in soil science has remained a specialized research area using primarily low-resolution medical-grade x-ray CT units that were not designed for soil analysis applications. The main research objectives were to characterize and compare physical properties of soil core samples from long-term chisel plow (CP) and no-till (NT) agricultural field management sites using a high-resolution industrial-grade x-ray CT unit and two conventional soil laboratory method (SLM) soil macroporosity analysis procedures. Field research activities during 1999 ...

Buffer Strips For Controlling Herbicide Losses, Steven K. Mickelson, James L. Baker 2016 Iowa State University

Buffer Strips For Controlling Herbicide Losses, Steven K. Mickelson, James L. Baker

Steven K. Mickelson

Buffer strips are considered effective for reducing runoff of sediment and agricultural chemicals from cropland. In fact, buffer strips, or vegetative filter strips, have been suggested as a Best Management Practice to reduce nonpoint source pollution from cropland. This pollution can be great, especially if rainfall occurs shortly after a chemical has been applied.

Impacts Of Cattle Grazing Management On Sediment And Phosphorus Loads In Surface Waters, M. M. Haan, J. R. Russell, Wendy J. Powers, J. L. Kovar, J. L. Boehm, Steven K. Mickelson, R. Schultz

Steven K. Mickelson

In 2001 (yr 1), 2002 (yr 2), and 2003 (yr 3), three blocks of five 1-ac paddocks were grazed by beef cows on hills at the Iowa State University Rhodes Research and Demonstration Farm to determine the effects of grazing management on phosphorus (P) and sediment runoff from pastureland. Grazing management treatments included an ungrazed control (UG), summer hay harvest with winter stockpiled grazing (HS), grazing by continuous stocking to a residual sward height of 2 in. (2C), rotational stocking to a residual sward height of 2 in. (2R), and rotational stocking to a residual sward height of 4 in ...

Livestock Manure Windrow Composting Runoff And Infiltration Characteristics From Laboratory Rainfall Simulations, David F. Webber, Steven K. Mickelson, Bryan D. Whitman, T. L. Richard, Heekwon Ahn 2016 Iowa State University

Livestock Manure Windrow Composting Runoff And Infiltration Characteristics From Laboratory Rainfall Simulations, David F. Webber, Steven K. Mickelson, Bryan D. Whitman, T. L. Richard, Heekwon Ahn

Steven K. Mickelson

Windrow-composted livestock manure has been shown to be less hazardous to the environment compared to manure directly applied to cropland and other agricultural areas. Although offsite contaminant losses through runoff and leaching can occur during the composting process, these losses are suspected to increase under different compost moisture conditions and as composted materials mature. This research quantified the effects of windrow-composted livestock manure and straw bedding components on runoff and infiltration characteristics from laboratory rainfall simulations. Compost samples collected on three dates at approximately the beginning (day 0), middle (day 30), and end (day 60) of a June-July 2004 field ...

Impacts Of Cattle Grazing Management On Sediment And Phosphorus Loads In Surface Waters, Mathew M. Haan, James R. Russell, Wendy Powers, John Kovar, Richard C. Schultz, Steven K. Mickelson

Steven K. Mickelson

The amounts of sediment and phosphorus (P) in water runoff from agricultural lands are of concern because of the potential for siltation and eutrophication of surface waters. There is limited information about the total sediment and P loads in runoff from pastureland in the Midwest. Because vegetation limits soil disruption caused by the impact of raindrops and forage roots hold soil particles, pastures grazed using suitable management practices should maintain water infiltration and minimize sediment and P losses in water runoff. Once sediment and P have been dislodged from the landscape, vegetative buffers can be an effective tool for reducing ...


Impacts From The Use Of Antibiotics In Livestock: Methods Of Transmission Of Antibiotic Resistance From Livestock To Humans, Kristin M. Walden 2016 Augustana College, Rock Island Illinois

Impacts From The Use Of Antibiotics In Livestock: Methods Of Transmission Of Antibiotic Resistance From Livestock To Humans, Kristin M. Walden

Biology: Student Scholarship & Creative Works

Antibiotic use in livestock production has been around since the 1950s. Antibiotic feed is used in livestock and other meat producing animals for three reasons: illness prevention, illness treatment, and growth promotion. Unfortunately, since the time that antibiotics were first invented, antibiotic resistant bacteria have become a threat to public health. There are many studies showing methods of transmission of antibiotic resistance from livestock to humans. Antibiotic resistance can spread from livestock to soil, water, insects, and food, which ultimately comes into contact with humans. A proposed study to measure antibiotic resistance when eliminating antibiotic feed will provide a hypothesis ...
