The Impacts of Land Management Practices on Soil Organic Carbon and Soil Physical Properties

K. Hamby, R. Story, D. Patey, C. Hale, I. P. Handayani, B. Parr, and M. Snider

Hutson School of Agriculture, Murray State University

ABSTRACT

To understand how to care for our soils, an understanding of soil physical properties must first be established. Soil organic carbon (SOC) refers to the carbon component of the organic compounds found in soil organic matter (SOM). SOC can be an indicator of soil structure, tilth, aeration, drainage, and stability. Soil pH is the measure of hydrogen ions suspended in a soil …

Measuring Palatability As A Linear Combination Of Nutrient Levels In Food Items, Jeffrey S. Young

Faculty & Staff Research and Creative Activity

It well known that palatability and nutritional quality of foods and/or diets are viewed as being in tension with one another. While there exist multiple measures of healthiness, there are no such measures for tastiness. This gap limits the degree to which researchers can investigate this tension and its implications for dietary behavior and hence public health and nutrition policy. The scope of future work concerning the dietary behavior of Americans would expand greatly if researchers better understood consumers’ willingness to eat certain foods, which matters as much as recommending those foods for them to eat in the first place. …

We Speak English Here: An Exploratory Study Of Language Barrier Effects In Agriculture, Camryn Clift

Honors College Theses

This thesis investigates the effects of the language barrier between English-speaking H-2A managers and their Spanish-speaking H-2A employees on Kentucky farms with special attention to the insights that can be gleaned from farm managers concerning the intersection of communication, language barriers, and the unique social and cultural environment created by the microcosm of the H-2A program. The project includes a literature review evaluating the currently documented effects of language barriers in various industries as they relate to the language barriers found within agriculture. IRB-approved interviews with farm managers provide original data to evaluate these potential effects, whether positive or negative. …

Soil Quality As Affected By Hemp And Grain Production Systems In Western Kentucky, Jack Eaker

Scholars Week

Since 2018, hemp cropping systems have become increasingly popular in Kentucky. However, there is limited data on soil’s behavior/changes under these management practices as compared to corn and soybean cultivation systems. Therefore, the objective of this study was to determine soil characteristics including soil organic matter, bulk density, water holding capacity, macroporosity, and water at field capacity in hemp and grain cropping systems. The thirty undisturbed soil samples were collected from three different hemp fields and a corn, soybean, and a bare field adjacent to these hemp fields. Each field was located at Murray State University West Farm, Calloway County, …

Science Of Climate Change In Agricultural Courses, Iin P. Handayani

Faculty & Staff Research and Creative Activity

Climate change adaptation is required knowledge for students and graduates from colleges of agriculture since recent crop production and food security are influenced by climate change. Thus, understanding the dynamics of climate change is important to support farmers to adapt to future conditions. However, not all students and graduates understand the concept and application of climate change with regard to the dynamics of food production and future food security. While agriculture faces the challenge of climate change adaptation, agricultural courses have not kept pace by incorporating climate change science into the curricula. To address this issue, eleven syllabi in selected …

The Viability Of Selected Potassium Solubilizing Rhizobacteria In A Mixture Of K-Feldspar And Organic Matter As Carrier Material, Diyan Herdiyantoro, Tualar Simarmata, Mieke R. Setiawati, Nenny Nurlaeny, Benny Joy, Mahfud Arifin, J S. Hamdaniand, Iin P. Handayani

Faculty & Staff Research and Creative Activity

The potassium solubilizing biofertilizer based on selected potassium solubilizing bacteria (KSB) can facilitate availability of potassium in primary silicate minerals containing potassium to be absorbed by the plants. The key to successful application of biofertilizer in showing positive effects on inoculated plants is the selection of a carrier material that can guarantee viability of inoculants during shelf life before being applied in the field. The purpose of this study was to determine viability of three selected KSB isolates which were formulated in a mixture of K-feldspar (KF), rice straw compost (RSC), rice husk biochar (RHB), and Aleksandrov liquid medium (ALM) …

Dirofilaria Immitis Prevalence In Canis Latrans In Kentucky, Melanie Ann Brandon

Murray State Theses and Dissertations

Dirofilaria immitis (canine heartworm) was found in forty-two (42) of the two hundred seventy-five (275) Canis latrans (coyote) necropsied in the state of Kentucky from November 27, 2019 through March 3, 2021. Thirty-five (35) of the positive cases were from western Kentucky region with the other seven spread across the state. With this group of coyotes, one hundred fifty-eight (158) were male and the other one hundred six-teen (116) were female. The estimated age ranged from a pup to senior dogs. A little over forty percent of the dogs were obtained through coyote/predator tournaments; the remaining were acquired from pest …

Work Ethic And Productivity: The Mediating Role Of Leadership, Everly Tapp

Murray State Theses and Dissertations

Employee work ethic and workplace productivity are vital for organizational success. Past research has shown leadership style to be influential on both, with the manager-employee relationship impacting employee’s attitude and output in the workplace. This study investigated the relationship between employee work ethic and workplace productivity, while also examining the impact of transformational, transactional, and laissez-faire leadership styles on agriculture equipment dealership employees. The leadership style of service managers, as measured by the Multifactor Leadership Questionnaire (MLQ) (5x-Short), was compared to the workplace productivity and work ethic scores of the service technicians they manage. Service technician workplace productivity data was …

Evaluating The Effects Of Residual Broiler Litter And Copper In Soil On Hemp (Cannabis Sativa L.) Fertility And Cannabinoid Production, Sarah E. Forden

Murray State Theses and Dissertations

This study encases two separate experiments observing hemp (Cannabis sativa L.) and soil fertility with the use of broiler litter and copper. The long-term broiler litter research plots were established in 1997 and the copper fertility research plots were not established until 2009. Both experiments use a randomized complete lock design with the broiler litter experiment composed of four replications and eight treatments at the following rates: 0, 1, 2, 3, 4, 5, 6, and 7 tons BL * ac^-1. The copper experiment was designed with four replications and three treatments at the following rates: 0, 10, …

Effectiveness Of The Two Plus Two Online Program In Agriscience Education: A Case Study Of Students’ Experiences And Persistence, Ronald M. Howell Jr

Murray State Theses and Dissertations

Higher education is changing, and more community colleges find themselves helping to increase the number of students who receive a bachelor’s credential from a 4-year post-secondary institution. This qualitative study was designed to determine the effectiveness of the online two plus two Agriscience Education program at a university in North Carolina. Twelve current and former students provided feedback about their perspectives and lived experiences through semi-structured interviews.

Preliminary findings suggest that both current and former students find the two plus two program very cost-affordable, flexible, and convenient for transferring two years’ worth of credit and courses to earn a bachelor’s …
