Soil Response Of Helicopter Liming In The Monongahela National Forest, Jarrett Douglas Fowler

Graduate Theses, Dissertations, and Problem Reports (ETD)

Soils in the Monongahela National Forest (MNF) are acidic due to sandstone parent material, acid deposition, uptake of base cations by vegetation, and release of organic acids by organic matter (OM) decomposition. Increases in soil acidity have caused declines in forest health and changed species composition and nutrient status. Liming can neutralize soil acidity, but no large-scale liming projects have been done on acid forest soils in the USA. In anticipation of acquiring funding for a proposed liming project in the MNF, in 2007 and 2009 10 sites were selected to sample and analyze soils before lime was applied. In …

Plant Species Identification In The Wild Based On Images Of Organs, Meghana Kovur

Graduate Theses, Dissertations, and Problem Reports (ETD)

Image-based plant species identification in the wild is a difficult problem for several reasons. First, the input data is subject to a very high degree of variability because it is captured under fully unconstrained conditions. The same plant species may look very different in different images, while different species can often appear very similar, challenging even the recognition skills of human experts in the field. The large intra-class and small inter-class image variability makes this a fine-grained visual classification problem. One way to cope with this variability and to reduce image background noise is to predict species based on the …

Research The Chopper Apparatus Of Equipment For Chopping Pressed Rough Fodders, Sh.H. Gapparov, N.A. Ashurov

Irrigation and Melioration

Livestock is one of the most important agricultural sectors in Uzbekistan and it is based on family livestock farms. On family farms, livestock animals are fed with pressed roughage, including corn stalks, alfalfa hay, barbed straw and wheat straw, mixed with concentrated feed. However, due to the lack of small choppers suitable for small farms, the compressed feed is fed to animals without chopping, as a result of which about 25-30 percent of them go to waste and there are large losses. Taking this into account, a small device was developed for chopping pressed roughage and mixing it with concentrated …

A Snapshot Semester: Students’ Reflections Of Performance And Mental State Throughout A Graduate Course, Bradley D. Borges

Graduate Theses and Dissertations

Graduate students are anecdotally reputed to be among the most stressed groups of young adults. Common sources of stress for graduate students have included coursework, assistantships, finances, career preparation, and family (Wyatt & Oswalt, 2013; Mazzola, Walker, Shockley & Spector, 2011; Oswalt & Riddock, 2007). Guided reflection can be used by educators to assist students in both learning (Boud, Keogh & Walker, 2013; Kolb, 1984) and managing stress (Shoulders, Whitehead, & Morrison, 2018). By understanding how students’ progress through a semester in terms of both their learning and their management of stress, instructors and academic advisors can better anticipate times …

Animal production and livestock published reports

To better understand the impacts of poor and variable seasons on lambing and turnoff rates, the Department of Primary Industries and Regional Development (DPIRD) conducts special short surveys on lamb marking rates. The data collected in 2020 adds to survey results from 2018, 2017 and 2011 to build a comprehensive picture for WA.

Marking rate (number of lambs per ewe mated) is an important measure to determine the rate of renewal of the state flock, potential turnoff and rate of genetic gain. It also an indicator of the impact of our highly variable seasons.

Women In Beekeeping: Impacts Of A Beekeeper Educational Program, Bridget Gross

Department of Entomology: Dissertations, Theses, and Student Research

The decline in honey bee populations over the past two decades in the United States is alarming. The management provided by beekeepers to their honey bee colonies influences the survival of the colony. However, there is a lack of information on the experiences of beekeepers, specifically women beekeepers. The Center for Rural Affairs (CFRA) in Nebraska hosted the “Honey Bees on the Farm: Connecting Women Beekeepers and Women Farmers for Environmental and Economic Benefit” program that provided informal, educational events to women beekeepers and landowners. Using a convergent mixed methods design, the first research question examines the impacts of the …

Entry-Level Workplace Competencies Needed By Graduates Of A Community College Agriculture Program: A Midwest Case Study Using The Delphi Technique, Blake Colclasure

Journal of Research in Technical Careers

Community colleges have a strong history of providing vocational education and occupational training to meet changing workforce demands of local industries. In the Midwest, agricultural industries have expressed an expanding need for middle-skilled workers with postsecondary, prebaccalaureate credentials. The 21st century agricultural landscape has changed as a result of the need for efficiency and sustainability, and resulting emergent agricultural technologies. Community colleges will be integral to establishing a qualified agriculture workforce for entry-level, middle-skilled positions. This study utilized a modified Delphi approach to identify entry-level workplace competencies needed by graduates of a community college agriculture program. Delphi panel experts represented …

In the first experiment, 50:50, 65:35 …

Leadership Styles And Barriers To Leadership For Women In Agriculture: A Mixed Methods Study, Erica Ramsey Louder

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Women are a growing demographic in agriculture, yet women holding positions in agricultural leadership is limited. This research sought to identify the ways women in agriculture lead by examining their leadership styles and the barriers they face as they strive to advance within their professions.

The results show that women are relationship-based leaders and that there are significant barriers that inhibit women’s advancement in agriculture. Many of these barriers are related to gender bias, self-perception, and life issues such as stress and workload.
