Will Saf Turbocharge The Corn Ethanol Market?, Richard Perrin, Lilyan Fulginiti, Felipe Miranda De Souza Almeida

Cornhusker Economics

The long-run outlook for the corn ethanol industry is questionable, due to a transition to electric and hybrid vehicles. One source of hope for the long run is the potential demand for producing Sustainable Aviation Fuel (SAF). SAF is a key component in the United States Aviation Climate Action Plan, a path to net-zero greenhouse gas (GHG) emissions in the aviation industry by 2050. Demand for ethanol for SAF offers hope to the ethanol industry, but it depends a great deal on policy decisions that are being made now. Here we sketch out this story.

Based on the information available …

Crop-Livestock Diversification And Efficiency In Agriculture, Jay Parsons, Maroua Afi

Cornhusker Economics

Diversification is a familiar strategy for managing risk in agriculture. It can take several forms including growing more than one crop or operating a farm with both crop and livestock enterprises. As with other strategies for managing risk, diversification comes with a unique set of costs. Managing a farm with multiple enterprises creates additional overhead as well as additional demands on management, labor, land, capital, and other resources. Diversification adds complexity to an operation and too much complexity can lead to inefficiencies.

Irrigation-As-A-Service For Smallholder Farmers, Ishani Lal

Department of Agricultural Economics: Dissertations, Theses, and Student Research

Irrigation is a crucial management practice that can help increase food security among smallholders globally while mitigating climate change impacts. High-efficiency irrigation technologies such as drip kits and sprinkler systems are relatively expensive and smallholder farmers cannot afford them to buffer crop yields against low precipitation. In many developing countries, farmers participate in robust informal markets for renting and sharing of irrigation equipment. Such services may be operated by farmers or via a third party such as irrigation start-ups, water user associations, non-governmental organizations, or even government agencies. These services are referred to collectively as Irrigation-as-a-Service (IaaS).

Deficit Irrigation Management For Irrigated Corn In Nebraska: Economically Viable?, Lia Nogueira, Cory Walters, Emily O'Donnell, Wesley Peterson, Suat Irmak

Cornhusker Economics

In this study we determine the economic value of deficit irrigation management using both technological and methodological advancements. The use of soil moisture probes represents the technological improvement. We provide improvements in the methodology as follows. Regarding data, we employ a field-size study, instead of plots, where the irrigation decision is determined by the moisture level in the soil measured through a soil moisture probe. Regarding the understanding of the yield response to water, although we examine the commonly used quadratic function, we improve upon this specification by also examining an alternative response function, the linear response stochastic plateau. Our …

2023 Nebraska Crop Production Budgets Higher Costs And Risks, Glennis Mcmclure

Cornhusker Economics

The Nebraska crop budgets are available for the 2023 production season. The 84 budgets indicate cost of production increases. Estimated average economic or total costs per bushel for 2023 corn production are expected to be at least 23% to 25% greater than last year. Soybeans are estimated to be 13% to 19% more in economic costs per bushel, with wheat production costs having jumped over 20% compared to last year and running as high as 63% higher over the last two years combined. Cost scenarios for individual producers can vary based on their timing of input purchases and price variabilities.

Hedging Your Average Crop Price Using Seasonals, Cory Walters, Richard K. Preston

Cornhusker Economics

In this article, we connect what the industry says and what producers say to improve the disconnect and the decision-making environment associated with hedging. We accomplish this by inspecting the distribution of producer prices with and without hedging in the fall as the distribution contains both yearly outcomes (producer concern) as well as the average outcome (another point of view). Computer models are used to lift the mystery surrounding the role of hedging. Computer models help understand complex processes, allowing for a better decision environment, leading to improved financial standing and stability. Our model reproduces the risk profile that individual …

Role Of Social Network On Technology Adoption: Application To Nebraska Producers In The Face Of Undesirable Vegetation Transitions, Sabrina Gulab, Holly K. Nesbitt, Simanti Banerjee, Theresa Floyd

Cornhusker Economics

Conclusion

Producers need to have access to information regarding new conservation practices and technologies to ensure land management in the face of ecological threats in general and vegetation transitions (VTs) in the context of our study. This study investigates the role of an individual producer's social network on the willingness to seek information about technologies and management practices and the likelihood of new technology adoption with special attention to risk attitudes and producer spillover effects. Our results provide evidence that network composition and information obtained through a producer's social network don't influence an individual's willingness to seek information about new …

Historical Corn Price Evolution Implications For Pre-Harvest Hedging, Cory Walters, Richard K. Preston

Cornhusker Economics

Commodity markets evolve through information provided by participating buyers and sellers and throughout this process the conditions in which commodity markets work are revealed. Producer pre-harvest commodity marketing can be further developed by incorporating information on how commodity markets work, leading to better farm financial performance.

We investigate how commodity markets have historically evolved from spring to fall. While changes in future prices appear random in any given year, observing average daily prices over 32 years could uncover a seasonal tendency. In the past 32 years, the average daily price tends to be higher in the spring than the fall, …

The Storm In World Fertilizer Markets Continues, John C. Beghin

Cornhusker Economics

This article updates the recent article on world fertilizer markets by Beghin and Nogueira (2021), which noted the perfect storm affecting global fertilizer markets through high demand, droughts affecting fertilizer supply, high fossil energy prices, COVID 19-related supply-chain disruptions, and trade policies, all conspiring to elevate fertilizer nominal prices to levels not seen since 2008. In the last 10 months, the Ukraine-Russia war and associated trade sanctions have exacerbated the disruptions in fossil energy, grain, vegetable oil, and fertilizer markets already present in 2021. On the more hopeful side, some United States trade policy developments will help reduce US fertilizer …

Assessment Of Grain Safety In Developing Nations, Jose R. Mendoza

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Grains are the most widely consumed foods worldwide, with maize (Zea mays) being frequently consumed in developing countries where it feeds approximately 900 million people under the poverty line of 2 USD per day. While grain handling practices are acceptable in most developed nations, many developing nations still face challenges such as inadequate field management, drying, and storage. Faulty grain handling along with unavoidably humid climates result in recurrent fungal growth and spoilage, which compromises both the end-quality and safety of the harvest. This becomes particularly problematic where there is little awareness about health risks associated with poor …

Utilizing Annual Forage Crops In Rotations, John Hewlett, Jay Parsons, Jeff Tranel

Extension Farm and Ranch Management News

First paragraph

Approximately 60 million acres of forage are harvested annually in the United States, according to the National Agricultural Statistical Service (NASS). With lower commodity grain and oilseed prices along with high pasture rental rates and/or difficulty finding range and pasture to rent, some producers are considering ways to incorporate more forages into their crop rotations.

Improving The Distribution And Use Of Biogas By Conversion To Methanol, Zachary Christman

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

In this technology review, the process of turning an average biogas into methanol will be presented. The purpose is to find a better method of transporting the energy contained within biogas so that it may be used in industry as a value added product. The first step is removal of hydrogen sulfide, a corrosive chemical that can breakdown mechanical parts. The second step is carbon capture and conversion of the biogas into hydrogen. The final step is the hydrogenation of carbon dioxide into methanol using a copper catalyst and an alcohol co-catalyst.

Modeling Effects Of Ecological Factors On Evolution Of Polygenic Pesticide Resistance, C. V. Haridas, Brigitte Tenhumberg

School of Biological Sciences: Faculty Publications

Widespread use of pesticides has resulted in the evolution of resistance in many insect pests worldwide, limiting their use in pest control. Effective pest and resistance management practices require understanding of the genetics of resistance and the life history of the pest. Most models for pesticide resistance assume that resistance is monogenic, conferred by a single gene. However, resistance could evolve as a polygenic quantitative trait resulting from the action of several genes, especially when pesticide dose is low. Further, fitness of the pest could be density dependent and might depend upon abiotic factors such as temperature. It is not …

Food Webs And Food Sovereignty: Research Agenda For Sustainability, Charles A. Francis, Michelle Miller, Molly Anderson, Nancy Creamer, Michelle Wander, Jacob Park, Thomas Green, Brent Mccown

Department of Agronomy and Horticulture: Faculty Publications

Future food production will be constrained by the scarcity of fossil fuel and fresh water as well as increasing intensity and unpredictability of weather events and climate changes. The assurance of food security and equity for many consumers is complicated by concentration of ownership of land and other production resources, as well as a global corporate food systems model that is driven by profit at the expense of people and the environment. To assess potential alternatives to the contemporary global food chain, well focused research is needed on local food production and food webs where small- and midscale family farms …

Intensive Production Of Millet And Sorghum For Evolving Markets In The Sahel, John H. Sanders, Botorou Ouendeba

INTSORMIL Scientific Publications

One principal constraint to improving the performance of millet and sorghum systems is overcoming the conventional wisdom. The conventional wisdom has some or all of these characteristics depending upon where you hear it. “Sorghum and millet are subsistence crops.” “They do not respond to fertilization.” “Even if they do respond to fertilizer, it is not profitable.” “Farmers will not use fertilization on these crops even if there were agronomic and economic responses.” “Banks will not lend to farmers for sorghum and millet fertilization.”

Does The Corn/Soybean Farmer Have Time For Alternative Crops? [Abstract], Lori A. Hoagland, Laurie Hodges, Glenn A. Helmers, James R. Brandle, Charles A. Francis

Department of Agronomy and Horticulture: Faculty Publications

Diversification of traditional row-crop farming in the Corn Belt is seen as advantageous in providing a wider economic base, decreasing economic risk associated with the link between commodity grain and cattle, increasing net farm income, and increasing biodiversity in the region. As farm size has increased to provide sufficient farm income, farm operations during the critical planting and harvesting windows are seen as limits to additional on-farm enterprises.

Agroecosystems Analysis From The Grass Roots: A Multidimensional Experiential Learning Course, Mary Wiedenhoeft, Steve Simmons, Ricardo Salvador, Gina Mcandrews, Charles A. Francis, James W. King, David Hole

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

An intensive, experiential travel course in Agroecosystems Analysis was conducted in Iowa, Minnesota, and Nebraska (United States) during summers of 1998 and 1999. The intended student audience was advanced undergraduate and beginning graduate students. Pretravel readings and a week-long series of farm visits, which consisted of in-depth interviews with the farmers and their families, prepared student teams to analyze and evaluate the production, economic, environmental, and social sustainability of 10 farms. Students shared their analyses both orally and in written reports. Based on a multifaceted student evaluation process, we found that participants were highly motivated, strongly engaged with the course …
