Importance Of Tree-And Species-Level Interactions With Wildfire, Climate, And Soils In Interior Alaska: Implications For Forest Change Under A Warming Climate, Adrianna C. Foster, Amanda H. Armstrong, Jacquelyn K. Shuman, Herman H. Shugart, Brendan M. Rogers, Michelle C. Mack, Scott J. Goetz, K. Jon Ranson

Aspen Bibliography

The boreal zone of Alaska is dominated by interactions between disturbances, vegetation, and soils. These interactions are likely to change in the future through increasing permafrost thaw, more frequent and intense wildfires, and vegetation change from drought and competition. We utilize an individual tree-based vegetation model, the University of Virginia Forest Model Enhanced (UVAFME), to estimate current and future forest conditions across sites within interior Alaska. We updated UVAFME for application within interior Alaska, including improved simulation of permafrost dynamics, litter decay, nutrient dynamics, fire mortality, and postfire regrowth. Following these updates, UVAFME output on species-specific biomass and stem density …

Challenges And Opportunities For Weed Control In Nebraska Popcorn, Ethann R. Barnes

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Weed control in popcorn is challenging with limited herbicide options and popcorn’s perceived sensitivity to herbicides. Understanding the impact of weeds maximizes yield and profit. New herbicide-resistant crops increase chances of drift or misapplication into popcorn, which doesn’t have herbicide-resistant traits. Herbicides that are labeled in popcorn are often only conditionally labeled with reduce rates, warnings, or limited popcorn types. Dent-sterility in popcorn is contingent on the Ga1 gene (Ga1-s), but this system is at risk from Ga1-m field corn introduced from Mexico because it overcomes dent-sterility. This risk is under-assessed as Ga1-m carriers are undocumented and Mexican germplasm usage …

Canavalia And Dolichos Extracts For Sustainable Pest Biocontrol And Plant Nutrition Improvement In El Salvador, Carlos Martinez

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Botanical repellents and pesticides are now being rediscovered as new tools for integrated pest management in order to reduce the use of toxic chemicals in crop production. Canavalia gladiata and Dolichos lablab are two Fabaceae very well adapted to farmlands of El Salvador, effective as living barriers and mostly as cover crops, however, they are not yet very well disseminated. This document describes the potential for using the liquid extracts and the dry flour of raw seeds of those plants for economic benefit and practical convenience for pest management in Salvadorian agriculture under field conditions. Seed extracts were useful when …

Using A Role-Driven Race Equity Reform Approach To Mitigate The Effects Of America's History Of Racism On Food Insecurity, Kenya N. Washington, Darryl E. Williams Jr.

Professional Agricultural Workers Journal

Abstract

Food insecurity, or the lack of reliable access to sufficient quantities of nutritious food, affects African Americans and other minorities disproportionately. This paper examines how America’s history of racism created and sustains the Nation’s racially disparate food system. Food insecurity contributes to hunger. This paper contemplates disparities in other American systems, including education and criminal justice, as exemplars of the broader ramifications of hunger. Finally, the paper examines the potential of individual action to address problems in any system. It champions the adoption of a role-driven race equity reform strategy as a tool to confront the current food insecurity. …

An Examination Of Heir Property, The 1980 Emergency Land Fund Study, And Analysis Of Factors That Influence African American Farmers' Actions Related To Farmland, Roy W. Copeland, William K. Buchanan

Professional Agricultural Workers Journal

Abstract

The study focused on heir property and analyzing African American farmers continuing in farming and dealing with clouded title. It specifically assessed the main issues raised by the 1980 Emergency Land Fund’s (ELF) study. It also surveyed a sample of African American farmers on heir property and related issues. It used descriptive statistics and logistic regression analysis to analyze the data. It found that 35% of respondents had a portion of their farms (50% or less) on heir property. This study reasonably confirms ELF’s findings on the percentage of African American-owned land held as heir property. Also, for farmers, …

Impact Of An Educational Program On A Year-Round Forage Production And Grazing Management System In Alabama, Lila Karki, Uma Karki

Professional Agricultural Workers Journal

Abstract

Raising animals on supplementary feeds in the lean months is economically unfeasible due to the increasingly high price of grains and commercial feeds. The objective of this study was to estimate the economic impact of educational events on year-round pasture and grazing management. A survey was introduced through SurveyMonkey to 78 trainees to collect data on a pre-structured questionnaire. A conceptual framework of production function was applied to measure the impact of the events using a before vs. after impact assessment approach. Forty-six percent of respondents completed the survey. The results revealed that the educational events had a positive …

Barriers To Management Intensive Grazing By Southern Dairy Farmers, Mohammed Ibrahim, Nalini K. Pattanaik, Brian Cornish

Professional Agricultural Workers Journal

Abstract

Interest in Management Intensive Grazing (MIG) [a situation where grazing animals are moved to a fresh pasture every few days in order to have access to adequate forage] practices by farmers have increased steadily over the years. Many research publications on grazing advocate the financial and environmental benefits of grazing. Understanding the challenges of MIG can be an important piece of information for a dairy farmer. A survey was conducted to determine how farmers in the southeastern region perceive the barriers to the adoption of MIG. A greater percentage of MIG southeastern farmers were satisfied or very satisfied with …

Toward Effective Rural Community Development In Black Belt Counties: Conceptual And Methodological Issues, Andrew Zekeri

Professional Agricultural Workers Journal

Abstract

The objectives of this paper are to (1) specify what “rural”, “community”, and “development” mean, and (2) what should be the essential steps to be taken to achieve an effective rural community development. Rural is a territorial concept, and it means an extent of dispersion of people in a local ecology. Community is a natural disposition among people who interact with one another on different matters that compromise a common life. Development is an organized intentional effort of local people to work together towards a shared goal. Community development is building the capacity of community residents to act effectively …

Insect Population Dynamics, Varietal Preference And Performance Of Organic Bio-Pesticides, Anitha Chitturi, Jeanine Davis, Margaret Bloomquist, Franklin Quarcoo, Kokoasse Kpomblekou-A, Desmond Mortley

Professional Agricultural Workers Journal

Abstract

Organic farming prohibits use of synthetic agrochemicals and encourages use of Integrated Pest Management (IPM) methods. States in the Southeastern US generally lag behind the rest of the country in organic vegetable production partly because of high insect pressures that make it difficult to grow vegetables without pesticides. This study on summer squash (Cucurbita pepo), grown using organic management practices, was conducted at a research station located in Mills River, North Carolina. The objectives of the study were to assess insect population dynamics and to evaluate performance of three OMRI-approved bio-pesticides: Azadirachtin, Pyrethrin and Spinosad against major …

Professional Agricultural Workers Journal

Abstract

Heavy metal contamination is a major anthropogenic challenge in communities with heavy presence of chemical industries. Most of the contamination is due to the improper disposal of chemical waste. The study involved the evaluation of the levels of arsenic and lead regarding remediation activities carried out by the Environmental Protection Agency (EPA). It compared the results of the EPA’s 1993 soil analysis of arsenic and lead, and a subsequent soil analysis of the same mapped areas. It also covered the evaluation of the level of arsenic dust in the attics of residential properties and evaluation of the EPA’s record …

Production Period Of Different Browse Species Suitable For Grazing Small Ruminants, Bidur Paneru, Uma Karki, Shailes Bhattrai, Nevershi Ellis

Professional Agricultural Workers Journal

Abstract

Browse (shrubs, trees, and vines) species are important sources of feed for small ruminants in Alabama and many other states of the U.S. Information on the production period of these species is important to prepare a year-round grazing plan to utilize them well. The objective of the study was to determine the leaf-shedding time of common browse species suitable for small ruminants. This study was conducted at the Atkins Agroforestry and Browse Research and Demonstration Site of Tuskegee University, Alabama. Ten samples of each browse species were tagged, and leaf-yellowing and leaf-fall data collected using photoplots every 14 days …

Swagriculture: A Qualitative Examination Of Women’S Participation In Samoa’S Agriculture Industry As Farmers And Growers, Charlotte Crandall

Independent Study Project (ISP) Collection

This study is an examination of how women participate in agriculture in Samoa as farmers and growers, what hardships women encounter and how they overcome these, and the organizations that influence people’s experiences. Censuses have historically undercounted the number of women in agriculture in developing countries, largely due to rigid international definitions of what counts as labor, which overlook cultural nuances, and this study aims to fill this gap in research. Data was collected through nine Talanoa-inspired interviews with women involved with farming or growing in Samoa, and overarching themes were analyzed. The themes have been grouped by the specific …
