Khrushchev and his successors would use Garst’s model for hybrid corn farming as the template for Soviet farming. Garst would use his limelight to catapult his corn diplomacy into action around the world. Lastly, the legacy of Khrushchev’s …

Next In Line: Exploring Owner, Business, And Family Characteristics And Farm Succession Planning, Tucker Lane Bittick

Graduate Theses/Dissertations

The growing average age of the American farmer raises concerns about who will be involved in the future agricultural economy. Efficient succession in family farms keeps farm values high, and farms that plan for succession have an incentive to invest more resources into the farm. Knowing what factors on family farms are common when succession occurs could help encourage earlier succession planning. The research questions were: “Are family, business, and owner characteristics significantly related to the presence of a farm succession plan on farms in the Midwest?” and “Are family, business, and owner characteristics significantly related to principal operators’ preference …

Regional Differences In Australian Export Grain Supply Chain Velocities And Their Implications, Ross Kingwell, Hemali Kanthilanka

Grain and Other Field Crops Research Articles

The size of grain harvests are increasing in most Australian states, enabling farmers to supply increasing volumes of grain to domestic and international customers. There is a market preference to supply international customers in the months prior to the availability of the northern hemisphere grain harvest that commences from June. To expedite export sales of Australian grain, most owners and operators of regional export grain supply chains in Australia are increasing their investments in the velocity, reliability, and capacity of their export grain supply chains. Larger volumes of Australian grain are now more rapidly exported. But what are the ramifications …

Consumer Preferences For Low-Methane Beef: The Impact Of Pre-Purchase Information, Point-Of-Purchase Labels, And Increasing Prices, Kelly A. Davidson, Brandon R. Mcfadden, Sarah Meyer, John C. Bernard

Agricultural Economics and Agribusiness Faculty Publications and Presentations

Cattle production is estimated to be the largest methane (CH₄) emitter associated with consumer demand in the United States of America (U.S.). With a national commitment to reducing methane emissions by 30% before 2030, methane-reducing additives (MRAs) in livestock feed are being explored as a viable solution. This study investigated consumer preferences for low-methane ground beef produced using one of three MRAs with varying levels of methane mitigation: Aspagopsis taxiformis (seaweed), the organic compound 3-nitroxypropanol (3NOP), or a blend of essential oils (e.g. garlic extract and citrus). In a nationally representative survey, 3,009 respondents completed a labeled discrete …

Nexus Between Rural Agricultural Land Ownership And Agricultural Credits Access: A Case Of Tanzania, Gelas Rubakula

Journal of Humanities and Social Sciences

Agricultural investment in low- and middle-income countries faces credit access challenges. Several financial institutions, particularly banks, normally impose some conditions where the possession of a land title deed is required to access agricultural credits. This paper examines whether, and to what extent, rural agricultural land ownership influences agricultural credit access for rural farmers in Tanzania. The study focuses only on rural farmers and tries to find out whether these smallholder farmers can use their land, which is largely unformalized, as a collateral for credit access. The study survey was cross-sectional, using quantitative data collected in December 2017 to March 2018 …

Leveraging Social Ties To Financial Gains: Exploring The Impact Of Social Capital In Rural Development, Mallory L. Rahe, Andrew J. Van Leuven, Trey Malone

Department of Agricultural Economics Faculty Publications

Social capital, defined as networks of individuals linked through bonding or bridging relationships, plays a crucial but poorly conceptualized role in place-based development. The word “capital” implies an underlying value of the social connections throughout a community, and this study explores how these social relationships are used to initiate, plan, access financial capital, and implement economic development projects in rural areas. We avoid county-level aggregation bias and use a divergent pathway case study of projects across eight communities to examine how social ties are used during rural development in places with both high and low financial capital. Both types of …

Place Branding: More Than Just A Logo, Marilyn R. Schlake

Cornhusker Economics

Place branding can distinguish one community from another. In a landscape of locations that provide the same amenities, environments, and opportunities, branding can help a community “stand out.” However, what is usually missing is a place brand developed in association with the community’s history, values, social connections, and organization associations that have evolved.

Investigating Consumer Perception And Wine Quality Impact On Alternative Packaging On Grape (Vitis), Mark Walker Bartz

Graduate Theses and Dissertations

The grape (Vitis species) and wine industry has major global economic impacts but faces issues with sustainability. The use of glass bottles for wine production is environmentally unsustainable due to energy-intensive manufacturing and poor recycling rates. However, wine consumers tend to associate glass bottles with higher quality over alternative wine packaging materials such as aluminum, polyethylene terephthalate (PET), and flexible bags/pouches. Since wine price and packaging influence consumers perception of wine quality, wine producers need to understand consumers to maximize profits. Thus, the overall objectives of this research were to investigate consumer perception and wine quality impact of alternative …

North Dakota Corn Efficiency Frontier: Stochastic Frontier Analysis, Bayarbat Badarch, David C. Roberts, Michael P. Popp

Agricultural Economics and Agribusiness Faculty Publications and Presentations

According to climate studies in North Dakota, the state's crop-growing season has been extended. In addition, many studies have shown technological advances in crop production. However, the state has not addressed how crop yield has been affected by weather changes. Thus, this paper investigates the state's corn (Zea mays) yield potential and efficiency measures based on agricultural input use and weather variables from 1994 to 2018. We found that the effects of temperature and precipitation on the state's corn yield frontier (potential) were greater than those of changing agricultural input variables. The stochastic frontier model indicates that the …

We collected data on plant type (slaughter, processing, both), the dominant livestock processed by the plant (predominantly beef, pork, poultry, and sheep/goat), plant capacity (maximum and typical capacity in slaughter head/day), age of establishment, and, whether the plant ceased, …

The Recreational Value Of Birding And Crane Abundance, Richard T. Melstrom, Alex Nielsen, Carson Reeling

Department of Agricultural Economics Faculty Publications

We estimate the economic value of birding, which is an important ecosystem service produced by bird populations in recreation areas. Our research identifies the link between values and species richness as well as the abundance of the sandhill crane (Grus canadensis), which migrates each year through our study area. Sandhill crane stopovers at state and federal wildlife areas can attract many birders. We estimate this nonmarket value using the zonal travel cost method and data from the eBird project on wildlife areas in Indiana. We compare crane counts based on eBird with those from the Indiana Department of Natural Resources …

Welcome To The New Frontier: Introducing Extension To The Next Generation Of Conservation Planning Tools, Emma E. Bravard, Emily K. Zimmerman, John C. Tyndall, David James

Journal of Extension

A new frontier of conservation planning capacity utilizing innovative decision support tools has emerged. Extension professionals play an important role in using these new data and tools to achieve conservation and water quality outcomes. Here, we detail the application of two conservation planning tools: Agricultural Conservation Planning Framework (ACPF) and Financial and Nutrient Reduction Tool (FiNRT). Tools like these are increasingly being used to guide conservation efforts in agricultural landscapes; provide information regarding potential resource concern; and offer valuable data about outcomes from best management practice (BMP) placement. Extension professionals’ use of such tools could enhance conservation implementation and outcomes.

Financial Analysis, Tina N. Barrett

Cornhusker Economics

The investment in a financial analysis can seem like a painful task of gathering information but the information it provides gives you invaluable information about your operation, especially when you don’t want to see it. I was once told a producer didn’t want to do the analysis anymore because the information made it hard to sleep at night. While not knowing maybe helped him sleep then, the problems that were being highlighted by the analysis didn’t go away and eventually caught up to him.

A Markov Regime-Switching Event Response Model: Beef Price Spread Response To Processing Capacity Shocks, Eunchun Park, Christopher N. Boyer, Clinton L. Neill

Agricultural Economics and Agribusiness Faculty Publications and Presentations

This research introduces a new method for event studies in time-series analysis named the Markov regime-switching event response model (MS-ERM). The MS-ERM is a comprehensive approach that integrates two different event study approaches: 1) measuring the impact of an event through structural shift and 2) measuring the impact via additional distributional components. As an empirical application, the study measures the impact of beef-packing plant closures on the weekly live-to-cutout beef price spread. The results indicate that the MS-ERM is a promising tool for event studies, particularly when an empirical dataset has both groups of events that cause and do not …

What Motivates The Choice To Custom Hire Pest Management Spraying Services?, Braeden Van Deye, Trey Malone

Department of Agricultural Economics Faculty Publications

BACKGROUND

This article presents a model of how farmers choose to custom hire for pest control. The decision-making process is illustrated through a discrete choice experiment conducted via a pilot survey of soybean growers in Michigan, Illinois, and Indiana. Farmers responded to a hypothetical pest infestation by choosing between custom operators, spraying on their own, or leaving the field to its fate.

RESULTS

Among farmers who choose to spray, the mean willingness to pay for marginal increases in timeliness (as defined as the chance of late spraying) ranges from 37 to 52 cents per acre. We also find that farmers …

The Costs Of Ecosystem Disturbances, E. Wesley F. Peterson

Cornhusker Economics

Presents an illustration of the interdependencies inherent in natural ecosystems. An ecosystem may be defined as: “… a single environment and every living (biotic) organism and non-living (abiotic) factor that is contained within it or characterizes it. An ecosystem embodies every aspect of a single habitat, including all interactions between its different elements” (Knapp 2020). In such interdependent systems, removal of one or more of the essential “elements” can severely disrupt the functioning of the system and such disruptions can give rise to negative impacts on the environment and human health and well-being.

Guide To Supplementary Feeding And Budgeting, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

Supplementary feeding of sheep, with grain, hay or silage is necessary when pastures or stubbles are deficient in energy and protein.

A good supplementary feeding program will ensure sheep utilise as much dry paddock feed as possible as well as provide sufficient supplementary feed for maintenance or growth.

The Department of Primary Industries and Regional Development recommends supplementary or confined paddock feeding to maintain livestock productivity and avoid animal welfare and soil erosion problems.
