Quantifying Plant Soluble Protein And Digestible Carbohydrate Content, Using Corn (Zea Mays) As An Exemplar, Carrie A. Deans, Gregory A. Sword, Paul A. Lenhart, Eric Burkness, William D. Hutchison, Spencer T. Behmer Aug 2018

Quantifying Plant Soluble Protein And Digestible Carbohydrate Content, Using Corn (Zea Mays) As An Exemplar, Carrie A. Deans, Gregory A. Sword, Paul A. Lenhart, Eric Burkness, William D. Hutchison, Spencer T. Behmer

Entomology Faculty Publications

Elemental data are commonly used to infer plant quality as a resource to herbivores. However, the ubiquity of carbon in biomolecules, the presence of nitrogen-containing plant defensive compounds, and variation in species-specific correlations between nitrogen and plant protein content all limit the accuracy of these inferences. Additionally, research focused on plant and/or herbivore physiology require a level of accuracy that is not achieved using generalized correlations. The methods presented here offer researchers a clear and rapid protocol for directly measuring plant soluble proteins and digestible carbohydrates, the two plant macronutrients most closely tied to animal physiological performance. The protocols combine …


Essays On Applied Welfare Economics., Sutirtha Bandyopadhyay Dr. Jun 2018

Essays On Applied Welfare Economics., Sutirtha Bandyopadhyay Dr.

Doctoral Theses

The measurement of welfare forms the foundation of public policy analysis. It is an area where empirical investigations clearly benefits from theoretical insight and where theoretical concepts are brought alive and appropriately focused by the discipline of empirical relevance and policy design. While welfare measurement at the micro level is of independent interest, of greater concern is the well-being of groups of households/individuals.A widely discussed issue in the literature of welfare economics is ‘whose welfare to measure’ when we are interested to measure the well-being of a group of individuals. The most common approach is to assume the existence of …


Animal Agriculture And American Health: The Search For Sustainable Protein, Britta Brinkmann May 2018

Animal Agriculture And American Health: The Search For Sustainable Protein, Britta Brinkmann

Biology: Student Scholarship & Creative Works

This study examines the impact large-scale animal agriculture has on the environment. It links the environment and health. The goal is to find protein sources that are sustainable and nutritious in order to replace typical meat and dairy products. A study is proposed to measure the impact of the typical American diet, a vegan diet, an insect-supplemented diet and a diet heavy in seafood.


Soil Properties That Influence The Occurrence Of Hydrogen Sulfide Toxicity In Rice Fields, Julia Marie Fryer May 2018

Soil Properties That Influence The Occurrence Of Hydrogen Sulfide Toxicity In Rice Fields, Julia Marie Fryer

Graduate Theses and Dissertations

Rice (Oryza sativa L.) producers face many challenges throughout each growing season. Hydrogen sulfide (H2S) toxicity is a physiological disorder where sulfate (SO42-) is excessively reduced to the toxic gas, H2S. This can reduce yield and, in severe cases, result in crop death. The main research objectives were to: i) understand chemical and physical characteristics in soils prone to H2S toxicity, ii) determine influential soil characteristics on the incidence of H2S toxicity, iii) determine ammonium sulfate ((NH4)2SO4) fertilizer additions influence on H2S toxicity, and iv) predict when and where H2S will occur. Three greenhouse experiments were conducted using Arkansas field …


The Impact Of Land Use On Nitrate-N Movement And Storage In The Vadose Zone Of The Hastings’ Whpa, Craig Adams Apr 2018

The Impact Of Land Use On Nitrate-N Movement And Storage In The Vadose Zone Of The Hastings’ Whpa, Craig Adams

School of Natural Resources: Dissertations, Theses, and Student Research

Nebraska has one of the largest agricultural economies in the United States and relies heavily on irrigation and fertilizer application to maintain crop yields. Over-irrigation and continuous application of nitrogen (N) in many areas has led to accumulation of nitrate-N in soils and sediments throughout the state’s vadose zone. Because nitrate-N is both persistent and mobile, groundwater concentrations in many areas of Nebraska and other agriculturally intensive states are increasing. Nitrate-N contamination of public and private drinking water supplies that utilize groundwater are of particular concern. Vadose zone sampling is an important method for rapidly assessing the effect of changing …


Modeling Effects Of Rainwater Harvesting Systems On Water Yield Increase And Non-Beneficial Evaporation Reduction To Sustain Agriculture In A Water-Scarce Region Of China, Tennille Wade Apr 2018

Modeling Effects Of Rainwater Harvesting Systems On Water Yield Increase And Non-Beneficial Evaporation Reduction To Sustain Agriculture In A Water-Scarce Region Of China, Tennille Wade

Civil & Environmental Engineering Theses & Dissertations

The northwestern region of China, which has an arid/semiarid climate, relies heavily on agriculture to provide food for the growing population. Climate change is affecting water availability in the region, causing long periods of drought and water scarcity followed by shorter periods of heavy rainfall and excess water availability. The ridge and furrow rainwater harvesting systems (RFRWHS) are a means of solving the problem of water scarcity; the systems can replenish soil moisture, reduce non-beneficial evaporation from bare soils, and increase surface water yield. In such a region, the hydrologic cycle is dominated by soil evaporation, leading to minimal surface …


Rain Rituals As A Barometer Of Vulnerability In An Uncertain Climate, L. Jen Shaffer Mar 2018

Rain Rituals As A Barometer Of Vulnerability In An Uncertain Climate, L. Jen Shaffer

Journal of Ecological Anthropology

Researchers and aid agencies, seeking to improve their understanding of local climate change responses, adaptation, and vulnerability, frequently interact with communities around the world who strongly emphasize their religious beliefs and practices. Dismissal and misunderstandings of these local perspectives can slow assessments of local climate vulnerability and development of adaptive capacity. In this paper, I show how analysis of rain ritual failure exposes the multiple stressors Ronga communities in southern Mozambique face, and as such, serves as a proxy measure for climate vulnerability at the local level. Oral histories and targeted interviews with participating elders, local chiefs, and community members …

Successful Climate Change Strategies In Corporate Farming In North America, Deann Renee Reaves Jan 2018

Successful Climate Change Strategies In Corporate Farming In North America, Deann Renee Reaves

Walden Dissertations and Doctoral Studies

The impact of climate change on agriculture is evident in changing growing seasons, crop yield, crop quality, and even complete crop losses. Changing climate conditions negatively affect the profitability of agricultural organizations. This study was a single descriptive case of one agricultural corporation in the western United States. The purpose was to identify and explore successful climate change-based sustainability strategies. The conceptual framework for this study was legitimacy theory. The data collection methods consisted of a semistructured interview of a corporate exectutive and obtaining corporate documents, including the annual report from the company's website. Data were analyzed using content analysis …


Assessing Intra-Event Phosphorus Dynamics In Drainage Water Using Phosphate Stable Oxygen Isotopes, William Ford Iii, Mark R. Williams, Megan B. Young, Kevin W. King, Eric Fischer Jan 2018

Assessing Intra-Event Phosphorus Dynamics In Drainage Water Using Phosphate Stable Oxygen Isotopes, William Ford Iii, Mark R. Williams, Megan B. Young, Kevin W. King, Eric Fischer

Biosystems and Agricultural Engineering Faculty Publications

Quantifying fluxes and pathways of dissolved reactive phosphorus (DRP) in tile-drained landscapes has been hampered by a lack of measurements that are sensitive to P fate and transport processes. One potential tool to help understand these dynamics is the oxygen isotope signature of phosphate (δ18OPO4); however, its potential benefits and limitations are not well understood for intra-event dynamics at the field scale. The objectives of this study were to quantify intra-event variability of δ18OPO4 signatures in tile drainage water and assess the efficacy of δ18OPO4 to elucidate mechanisms and flow …
