Measuring Mobility: A Quantitative Description Of Sbae Teacher Mobility In Minnesota, Becky Haddad, Lavyne L. Rada, Amy R. Smith

Department of Agricultural Leadership, Education, and Communication: Faculty Publications

Considerations around teacher attrition, supply and demand, and retention are incomplete without including teacher mobility. The problem, as it currently stands, finds SBAE ill-equipped, at the professional level, to support mobile teachers. Providing support, however, starts with understanding the population; in this case, mobile teachers. The purpose of our study was to quantitatively describe teacher mobility in [State] over the last 20 years (1999-2021). To describe SBAE teacher mobility in our state, we utilized teacher retention data compiled from state teacher directories over the last 20 years (1999-2021). We corroborated previous findings noting heightened attrition after year one in a …

One-Participant 401(K) As A Tool For Farmers And Ranchers, Jessica Groskopf, Cory Walters, Doug Nelson

Center for Agricultural Profitability

According to USDA, only 40% of farm households participate in some type of retirement account. For self-employed farmers and ranchers without full-time employees, the opportunity to invest in a One-Participant 401(k) plan is a way to (1) save money for retirement, (2) reduce taxable income, and (3) provide the potential option to borrow from the plan. This series of articles will review these features.

What is a One-Participant 401(k)?

The One-Participant 401(k)is a qualified retirement plan designed specifically for business owners with no full-time employees other than the business owners and their spouses. Visit with your financial planner and tax …

One-Participant 401(K): Saving For Retirement And Reducing Taxes, Jessica Groskopf, Cory Walters, Doug Nelson

Center for Agricultural Profitability

The adage that farmers and ranchers are often asset-rich and cash poor does indeed appear to be true! According to the United States Department of Agriculture (USDA), just forty percent of farmers contribute to a retirement plan. And because many farmers and ranchers invest profits in their business rather than take a high salary, they show little income on their tax returns. This means they will have paid less into Social Security and their benefits will be lower when they retire. This can create cash flow challenges, especially for an older generation of farm and ranch families wanting to bring …

What Happens To Your Farm Or Ranch If You Become Disabled?, Jessica Groskopf

Center for Agricultural Profitability

Estate and transition planning often focuses on what happens to the farm or ranch at the death of a key person. However, a good estate and transition plan should also include contingencies for disability. Planning for a disability is not an easy task because the severity and duration of the disability are unknown. This article offers some key items to have in place to protect you and your operation from disability.

Recognizing Power And Control When Planning Your Estate, Allan Vyhnalek

Cornhusker Economics

The older generations have spent their entire professional lives using the power and control that they accumulated through hard work and their long tenures. Having them retire and give up that control and power is difficult for some in those generations. Overall, it is challenging for them to give up control or power.

Investigation Of Breeding Objectives And Indexes-In-Retrospect, Hunter F. Valasek

Department of Animal Science: Dissertations, Theses, and Student Research

This thesis presents two projects that investigate the impacts of breeding objectives and indexes-in-retrospect within the beef cattle industry. The first project synthesized how changes due to planning horizon, breeding system, and sale endpoint in the economic breeding goal of cattle influence the relative emphasis of traits as well as the re-ranking of selection candidates. A total of three breeding systems that represent straightbred and crossbred cattle were used along with six planning horizons (2, 5, 10, 20, 30, and 50 yrs.) for both a weaning and slaughter point of sale. The combination of these different breeding objective attributes resulted …

Feed Value And Utilization Of Corn Residue: Implications For Cow Performance And Grazing Strategies, Kaylee E. Wheeler

Department of Animal Science: Dissertations, Theses, and Student Research

Two experiments were conducted to determine the correlation of corn residue feed value and utilization on cow performance and potential grazing strategies. A qualitative observation of corn residue grazing by 13 cattle herds across Nebraska was conducted over two years. Based on producer reported grain yields and stocking rates, it was found that these producers were generally not as aggressive as the recommended 1.2 animal unit months (AUM) for each 6,280 kg/ha (100 U.S. bushels/acre) of harvested grain. They stocked 17 to 101% of the recommendation and on average used 63% of the carrying capacity. Across herds, average body condition …

Vulnerabilities Of Greater Prairie Chicken And Tier 1 At-Risk Species In Nebraska Caused By Grassland Transition To Woody Dominance, Robert Peterson

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

Woody plant encroachment is a global threat and has been transitioning grasslands to woody dominance at a biome scale. This threat is present in the Great Plains grassland biome which is currently experiencing grassland biome collapse as the alternative woody biome advances northwest. Nebraska, which contains the most intact temperate grassland in the world, is currently at the front lines of this large-scale transition making this state’s management decisions vital for the remaining grasslands and the species which rely on these ecosystems. In this study, we assess the vulnerability of Greater Prairie Chicken and Tier 1 at-risk species in Nebraska …

High Throughput Phenotyping: Field Based Triticale Breeding And Educational Resource Impact, Catherine Kay Mick

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

Triticale (Triticosecale) is a multifunctional hybrid cereal crop that adopted the hardiness of rye and wheat's high-yielding and nutritional qualities. Plant breeding programs work to improve the quality and number of varieties available to producers through multiple rounds of evaluation and selection. However, traditional phenotyping methods are labor-intensive, time-consuming, and destructive, creating a phenotyping bottleneck. Remote sensing using unmanned aerial systems has the potential to alleviate this issue and change the evaluation of phenotypes in a breeding. Demand for educational resources to advance public awareness and prepare the workforce has increased with the utilization of more technology in …

Aicropcam: Deploying Classification, Segmentation, Detection, And Counting Deep-Learning Models For Crop Monitoring On The Edge, Nipuna Chamara, Geng (Frank) Bai, Yufeng Ge

Biological Systems Engineering: Papers and Publications

Precision Agriculture (PA) promises to meet the future demands for food, feed, fiber, and fuel while keeping their production sustainable and environmentally friendly. PA relies heavily on sensing technologies to inform site-specific decision supports for planting, irrigation, fertilization, spraying, and harvesting. Traditional point-based sensors enjoy small data sizes but are limited in their capacity to measure plant and canopy parameters. On the other hand, imaging sensors can be powerful in measuring a wide range of these parameters, especially when coupled with Artificial Intelligence. The challenge, however, is the lack of computing, electric power, and connectivity infrastructure in agricultural fields, preventing …

Agriculture And Community Well-Being: A Review Of Three Research Studies., Marilyn R. Schlake

Cornhusker Economics

Personal observations are often obscure to the facts. For instance, recently I worked at a booth at Husker Harvest Days. The booth focused on rural community development. My observations were that many of the agricultural producers decided to not stop at our booth or for those who did stop, conversations showed a disconnect of the importance of their local community to their farm operations. Similarly, when working with communities, I have observed the lack of understanding of the importance of the agricultural producers to the local community’s well-being. Why the disconnect between these two very important components of our rural …

Pass-Through Entity Tax Deduction, Tina N. Barrett

Cornhusker Economics

In 2023, the State of Nebraska became the 36th state to implement a Pass-Through Entity Tax (PTET) Deduction law. This law is in response to a change made by the federal Tax Cuts and Jobs Act of 2018 which limited the state and local tax deduction eligible for itemized deductions to $10,000. This new state law allows partnerships and s-corporations to pay the state income tax on behalf of their owners which qualifies it for a federal tax law deduction. The individuals will then receive a credit on their individual return for the tax paid on their behalf.

2024 Nebraska Crop Budgets — A Mixed Review With Some Costs Higher, Some Lower, Glennis Mcmclure

Center for Agricultural Profitability

While field operation costs are projected higher for the 2024 Nebraska crop enterprises, some material input costs are lower than were projected for 2023. One driving force on lower cost projections for 2024 is 20% to 40% less on fertilizer prices is factored in on many budgets, and five pounds less nitrogen fertilizer was entered for a majority of the corn budgets due to continued improvement of application practices. Cost scenarios for individual producers can vary based on their timing of input purchases and price variabilities. The 84 1Nebraska crop budgets are now available online in three formats with a …

Does Selection For Seedling Tiller Number In Perennial Biomass Feedstocks Translate To Yield And Quality Improvements In Mature Swards?, Robert B. Mitchell, Kenneth P. Vogel, Susan Tunnell, James Stubbendieck

Department of Agronomy and Horticulture: Faculty Publications

Breeding for seedling traits in herbaceous perennial biomass feedstocks that translate into increased biomass yield or quality in established swards could accelerate the development of perennial grass cultivars for bioenergy or forage. In previously reported research, breeding for single large tillers (ST) or multiple tillers (MT, ≥3) six weeks after planting for two generations in big bluestem (Andropogon gerardii Vitman) and switchgrass (Panicum virgatum L.) base populations produced ST and MT populations that differed significantly for seedling and mature plant traits including biomass yield in spaced planted nurseries. Our objective was to evaluate these ST and MT populations in sward …

What Is Irs Section 180 And How Does It Work?, Shannon Sand

Will Nebraska Farms And Ranches Be Ready For Double Digit Operating Line Rates?, Jeffrey Stokes, Jim Jansen

Cornhusker Economics

For those involved in agriculture, it has been quite a while since interest rates on farm real estate, equipment, and operating lines have been as high as they are for the industry. As the fall harvest winds down and producers focus on next year, interest rates on operating lines may cause shock. It has been over 20 years since interest rates on operating lines exceeded 10%. To better understand what may be causing interest rates on operating lines to rise, it will be beneficial to understand some basic monetary policy tools the Fed has at its disposal. The tool receiving …

How Much Nebraska Ag Land Is Owned By Foreign Entities?, Larry W. Van Tassell

Center for Agricultural Profitability

The Agricultural Foreign Investment Disclosure Act of 1973 (AFIDA) established a mandatory reporting system, overseen by the USDA, that requires foreign entities to provide information on all U.S. agricultural and non-agricultural land in which they hold an interest. “Interest” is reported as a fee interest (legal possession of both the surface and mineral rights), partial fee interest (must state percent ownership), life estate, trust beneficiary, purchase contract, or other. “Other” includes leases that are 10-years or longer. The regulations exempt foreign entities with interests solely in mineral rights and leases of less than 10 years in duration from reporting. In …

Notes From The Brazilian Cornfields, Fabio Mattos

Cornhusker Economics

In the last few months, I have been traveling in Brazil. My objective with this trip is to meet with industry professionals, government officials, and academic researchers to learn about recent developments in Brazilian agriculture and what we can expect to see in the future. I have essentially been asking people their opinions about the main developments in Brazil in the last few years and their perspectives for the future. One of the main topics that has emerged consistently in these conversations is, not surprisingly, the corn market.

Do Only Americans Own America? Foreign Investment In Agricultural Lands In The United States, Larry W. Van Tassell

Center for Agricultural Profitability

Foreign investment in the United States, while not a new phenomenon, has recently caught the attention of the American public and members of the U.S. House and Senate after an Air Force officer raised concerns when the Fufeng Group, based in Shandong, China, purchased 300 acres of farmland 12 miles from an Air Force base in Grand Forks, North Dakota, to build a corn milling plant (Javers, 2022). National security concerns prompted the U.S. Senate to propose a bill prohibiting the purchase of land in the U.S. by companies or individuals from China, North Korea, Iran, or Russia.

Diesel Tractor Fuel Efficiency And Exhaust Emissions Standards, Jerin Tekolste, Cory Walters, Michael Mccullough, Lynn Hamilton, Lia Nogueira, Roger M. Hoy

Cornhusker Economics

Diesel engine performance and costs represent crucial factors for agricultural producers while pollutants from the exhaust are largely a social concern but also important to producers. Beginning in 1970, Congress authorized the Environmental Protection Agency to regulate emissions with amendments in subsequent years (U.S. EPA, 2023). In 1996 the EPA issued strict Exhaust Emission Standards for Nonroad Compression-Ignition Engines, causing a major paradigm shift in acceptable emission levels. A primary concern coming from many manufacturers was the difficulty of designing an engine to meet these standards without compromising the engines’ power output and efficient fuel consumption (Lloyd and Cackette 2001; …

Wics Conference 2023: Moving Beyond The Ordinary, Daren Redfearn, Daran Rudnick

WICS Conferences

The theme of this year’s WICS Conference is Moving Beyond the Ordinary with the goal of addressing Team Science. Our vision is to provide opportunities and connection points among IANR faculty to leverage their individual knowledge, skills, abilities, and passions. A tendency for land grant institutions is often to deliver information biased from a single, primary discipline and perspective. This is known as comfort zone mega bias and has been defined as “the tendency to drag a problem into our comfort zone and solve the problem that we know how to solve, rather than solving the problem that needs to …

Farming For Nebraska's Future: Regenerative Agriculture In The Cornhusker State, Megan Buffington

Honors Theses

This reporting project started, as many do, with questions: Who is practicing sustainable agriculture in Nebraska? Why? What is stopping others from doing the same? And what even is sustainable agriculture?

Over the course of this project, I spoke with farmers, ranchers and academics, eventually learning that regenerative agriculture is the more widely used term, and there are a wide swath of systemic barriers preventing more producers from adopting it. But for those who do take the leap, the unconventional method leads to personal and financial well-being traditional agriculture never provided. The final project is made up of three articles …
