Managing Saline And Sodic Soils And Irrigation Water, Burdette Barker, Grant Cardon, Matt Yost, Melanie Stock, Earl Creech, Jody Gale

All Current Publications

Salt is an important factor in plant and soil management. Excessive salt concentrations in soil can cause water to be less available to plants because of the osmotic forces of salt in the soil water. Excessive concentrations of different ions can also be toxic to plants. In agricultural soils and irrigation water, salts are typically described in two ways: (1) total salt concentration or salinity, and (2) sodicity, or the concentration of sodium relative to other cations (positively charged atoms or compounds). Understanding the effect of both total salinity and sodicity on plants and soils, along with management and reclamation …

Increasing Workforce Skills: The Possible Disconnect Between Employers And Potential Job Seekers, Cheryl A. Burkhart-Kriesel 2024 University of Nebraska-Lincoln

Increasing Workforce Skills: The Possible Disconnect Between Employers And Potential Job Seekers, Cheryl A. Burkhart-Kriesel

Cornhusker Economics

In a multi-year survey of potential job seekers, those who are likely to change jobs in the next year or who are likely to reenter the workforce in the next year, several key training obstacles for improving their employment situation were identified. There seemed to be only slight differences in how they viewed these challenges, regardless of whether they saw their potential job as a career, a steppingstone to a career, or just a job to get by. The cost of training, the lack of available training, the distance or transportation to the training, lack of time, and the knowledge …


Paying Family Members On The Farm Or Ranch, Jessica Groskopf 2024 University of Nebraska-Lincoln

Paying Family Members On The Farm Or Ranch, Jessica Groskopf

Center for Agricultural Profitability

For many farm and ranch families, bringing children or grandchildren into the operation is the ultimate goal. Successfully bringing additional family members into the operation may require some creativity as all parties need to maintain a viable standard of living. This is the first in a series of articles that will highlight ideas and tactics for bringing another family member into the operation.

One tactic is to provide new family members with monetary compensation, such as an hourly wage or salary. The total compensation should be comparable to the market value of wages to hire a non-family member to do …


Embracing Diversity In Agricultural Economics, Timothy L. Meyer 2024 University of Nebraska-Lincoln

Embracing Diversity In Agricultural Economics, Timothy L. Meyer

Cornhusker Economics

To steal an overused cliché, “There’s room in the tent for everyone.” Over the 2023 academic year, I have reiterated this message to all my students, with one addition. Not only is there room for everyone, but all are invited AND welcome. Food is something we all have in common, no matter the background. I think this is why producers in the state of Nebraska feel as strongly as they do about the food they produce; it is life-giving and should be taken seriously. Nebraska Agriculture is part of what makes our state great, and that is not a secret …


Fear, Racism, Agriculture: The Drive For Japanese Internment, Brandon James March 2024 Liberty University

Fear, Racism, Agriculture: The Drive For Japanese Internment, Brandon James March

Doctoral Dissertations and Projects

The focus of this dissertation is the timing of the forced evacuation of the ethnic Japanese population from the West Coast in 1942. This work focuses on three key factors driving the timing of the evacuation: racism, security concerns, and agriculture. Racism has been studied and written about extensively; however, an overview of this factor is critical as it directly influenced the removal of Japanese American citizens in addition to Japanese immigrants. This dissertation will focus on the intellectual origins of racism and prejudice by focusing on key figures and tracing the ideas and beliefs and how they influenced the …

Faculty Publications – Biological Sciences

Pennycress (Thlaspi arvense L.) is an annual cover crop known for its exceptional cold tolerance and high oil and protein yields. Pennycress can be integrated into a corn–soybean rotation in the U.S. However, the utilization of pennycress biomass remains largely unexplored, including assessing compositional changes through its growth and organic matter digestibility. This study harvested pennycress at three growth stages, characterized the biomass for anaerobic digestion (AD), and tested the effects of concurrent alkali pretreatment and ensiling on the biomass methane yield. Results showed that the biomass harvested when the plants were undergoing senescence (“third-harvest”) had higher contents of …

The Importance Of Strategic Planning For Farmers And Ranchers, Larry Van Tassell

Center for Agricultural Profitability

Planning, or more specifically, strategic planning, is a process of defining long-term goals and objectives of an organization and determining the best course of action to achieve them. It involves such steps as defining the current situation, identifying strengths, weaknesses, opportunities, and threats, and developing a plan of action to take advantage of opportunities and overcome challenges. Parsons (2018) outlined six key components of a business plan and why a farm or ranch should make the effort to develop a business plan.
