Six Key Components Of A Farm Or Ranch Business Plan, Jay Parsons Dec 2018

Six Key Components Of A Farm Or Ranch Business Plan, Jay Parsons

Cornhusker Economics

Developing a good farm or ranch business plan can have many benefits. In an earlier Cornhusker Economics article, I outlined six good reasons to develop a business plan (Parsons 2015). It helps to get your business organized and moving in the right direction. It lets your lender know you have a plan to succeed, which opens up your access to capital. It also helps you organize your thoughts, clarifying the goals and objectives you wish to achieve. In summary, putting together a written business plan increases the likelihood of your business achieving success (Scarborough 2011).


Jerome Powell Is Not The Bad Guy, Tim L. Meyer Dec 2018

Jerome Powell Is Not The Bad Guy, Tim L. Meyer

Cornhusker Economics

One of the maxims often heard in economics, agriculture, and politics is that those who do not learn from history are bound to repeat it. At first glance, this is a pessimistic view of human behavior. However, I believe that in some part it is a reflection of the positive spirit exhibited by many Americans. While it is true some have not bothered to learn from history, others have simply emphasized the positive times while simultaneously limiting the memory of more challenging experiences.


Implications Of Spatially Variable Costs And Habitat Conversion Risk In Landscape-Scale Conservation Planning, Max Post Van Der Burg, Neil Chartier, Ryan Drum Dec 2018

Implications Of Spatially Variable Costs And Habitat Conversion Risk In Landscape-Scale Conservation Planning, Max Post Van Der Burg, Neil Chartier, Ryan Drum

USGS Northern Prairie Wildlife Research Center

‘‘Strategic habitat conservation’’ refers to a process used by the U.S. Fish and Wildlife Service to develop cost-efficient strategies for conserving wildlife populations and their habitats. Strategic habitat conservation focuses on resolving uncertainties surrounding habitat conservation to meet specific wildlife population objectives (i.e., targets) and developing tools to guide where conservation actions should be focused on the landscape. Although there are examples of using optimization models to highlight where conservation should be delivered, such methods often do not explicitly account for spatial variation in the costs of conservation actions. Furthermore, many planning approaches assume that habitat protection is a preferred …


Prairie Reconstruction Unpredictability And Complexity: What Is The Rate Of Reconstruction Failures?, Jack E. Norland, Cami Dixon, Diane Larson, Kristine Askerooth, Benjamin A. Geaumont Dec 2018

Prairie Reconstruction Unpredictability And Complexity: What Is The Rate Of Reconstruction Failures?, Jack E. Norland, Cami Dixon, Diane Larson, Kristine Askerooth, Benjamin A. Geaumont

USGS Northern Prairie Wildlife Research Center

The outcomes of prairie reconstructions are subject to both unpredictability and complexity. Prairie, tallgrass, and mixed grass reconstruction is defined as the planting of a native herbaceous seed mixture composed of multiple prairie species (10 or more) in an area where the land has been heavily cultivated or anthropogenically disturbed. Because of the unpredictability and complexity inherent in reconstructions, some outcomes end up being failures dominated by exotic species. We propose that these failures follow a fat-tailed distribution as found in other complex systems. Fat-tailed distributions follow the Pareto principle, where 80% of the time reconstructions work as expected but …


Do We Need More Futures Contracts In Commodity Markets?, Fabio Mattos Nov 2018

Do We Need More Futures Contracts In Commodity Markets?, Fabio Mattos

Cornhusker Economics

In the last couple of months, there has been news about a new futures contract for soybeans. The Financial Times and Reuters, among others, reported that the CME Group, the world’s largest futures exchange, is considering launching a futures contract based on Brazilian soybeans. The discussion seems to have started after trade issues between the United States and China resulted in a 25 percentage-point tariff on U.S. soybeans exported to China. As Chinese buyers try to avoid the tariff by purchasing grain from other suppliers, notably Brazil, a new price dynamics between U.S. and Brazilian soybeans could be emerging. This …

Agricultural Production From The High Plains Aquifer Is Worth Over $3 Billion Per Year, Richard K. Perrin, Lilyan E. Fulginiti, Federico Garcia

Cornhusker Economics

Recent research (Garcia, Fulginiti and Perrin, 2018) has shown the that the extra agricultural production from irrigation across the High Plains Aquifer (HPA) was worth about $3.5 billion in 2007, $2 billion of which was produced in Nebraska. The aquifer water is valuable!


The Economics Of The Capitalization Rate For Farmland, Jeff Stokes, Jim Jansen Nov 2018

The Economics Of The Capitalization Rate For Farmland, Jeff Stokes, Jim Jansen

Cornhusker Economics

There are three approaches that real estate appraisers use to value real property, namely, the market or sales comparison approach, the income approach, and the cost approach. The sales comparison approach is the primary way that residential real estate is appraised with the cost approach thrown in for good measure. For income producing properties, which includes commercial real estate as well as farm real estate, all three approaches are frequently used. When there are minimal improvements on farmland, the sales comparison and income approaches often provide competing estimates of value that must be reconciled so that an appraiser can render …


Examining Patterns In Nest Predation Using Artificial Nests, Victoria L. Simonsen Nov 2018

Examining Patterns In Nest Predation Using Artificial Nests, Victoria L. Simonsen

School of Natural Resources: Dissertations, Theses, and Student Research

The use of artificial nests to study the predation of avian nests has faced disregard by ecologists due to inconsistencies found between the survival rates of real and artificial nests across studies and reviews. The negative perception of artificial nests providing an inconsistent assessment of survival has thus fostered the perception that artificial nests are a secondary option to be used to overcome logistical hurdles associated with achieving sufficient sample sizes in systems where study species are rare or elusive, or as merely a preliminary method to study predation across gradients. We argue that the greatest mistake ecologists have made …


13 Terrestrial Wetlands, Randall Kolka, Carl T Trettin Nov 2018

13 Terrestrial Wetlands, Randall Kolka, Carl T Trettin

USGS Northern Prairie Wildlife Research Center

The objective of this chapter is to characterize the distribution of carbon stocks and fluxes in terrestrial wetlands within North America. The approach was to synthesize available literature from field measurements with analyses of resource inventory data to estimate wetland area, carbon stocks, and net ecosystem exchange (NEE) of carbon and methane (CH4) fluxes of terrestrial wetlands (see Appendices 13A, p. 547, and 13B, p. 557, for details1). Then, the findings employed from large-scale simulation studies provided additional context, with consideration given to the effects of disturbance regimes, restoration and creation of terrestrial wetlands, and the application of modeling tools …


Initiative 427: Nebraska Medicaid Expansion, J. David Aiken Oct 2018

Initiative 427: Nebraska Medicaid Expansion, J. David Aiken

Cornhusker Economics

This article summarizes information regarding Initiative 427–the Medicaid expansion question on the November 6, 2018 ballot. It reprints the actual ballot language and the Nebraska Secretary of State’s summary of arguments for and against Initiative 427.

Background. Originally Medicaid covered the elderly, the disabled, children in low-income families, and low-income pregnant women. In 2010 Medicaid coverage was expanded by Congress to include the working poor. In 2012 the U.S. Supreme Court ruled that the provision of the Affordable Care Act (ACA) requiring states to expand Medicaid was unconstitutional. This made it a state option whether or not to expand Medicaid. …


Landscape Genetics Reveal Broad And Fine‐Scale Population Structure Due To Landscape Features And Climate History In The Northern Leopard Frog (Rana Pipiens) In North Dakota, Justin M. Waraniak, Justin D. L. Fisher, Kevin Purcell, David M. Mushet, Craig A. Stockwell Oct 2018

USGS Northern Prairie Wildlife Research Center

Prehistoric climate and landscape features play large roles structuring wildlife populations. The amphibians of the northern Great Plains of North America present an opportunity to investigate how these factors affect colonization, migration, and current population genetic structure. This study used 11 microsatellite loci to genotype 1,230 northern leopard frogs (Rana pipiens) from 41 wetlands (30 samples/wetland) across North Dakota. Genetic structure of the sampled frogs was evaluated using Bayesian and multivariate clustering methods. All analyses produced concordant results, identifying a major east–west split between two R. pipiens population clusters separated by the Missouri River. Substructuring within the two major identified …

Multi-Element Fingerprinting Of Waters To Evaluate Connectivity Among Depressional Wetlands, Yuxiang Yuan, Xiaoyan Zhu, David M. Mushet, Marinus L. Otte Oct 2018

Multi-Element Fingerprinting Of Waters To Evaluate Connectivity Among Depressional Wetlands, Yuxiang Yuan, Xiaoyan Zhu, David M. Mushet, Marinus L. Otte

USGS Northern Prairie Wildlife Research Center

Establishing the connectivity among depressional wetlands is important for their proper management, conservation and restoration. In this study, the concentrations of 38 elements in surface water and porewater of depressional wetlands were investigated to determine chemical and hydrological connectivity of three hydrological types: recharge, flow-through, and discharge, in the Prairie Pothole Region of North America. Most element concentrations of porewater varied significantly by wetland hydrologic type (p < 0.05), and increased along a recharge to discharge hydrologic gradient. Significant spatial variation of element concentrations in surface water was observed in discharge wetlands. Generally, higher element concentrations occurred in natural wetlands compared to wetlands with known disturbances (previous drainage and grazing). Electrical conductivity explained 42.3% and 30.5% of the variation of all element concentrations in porewater and surface water. Non-metric multidimensional scaling analysis showed that the similarity decreased from recharge to flowthrough to discharge wetland in each sampling site. Cluster analysis confirmed that element compositions in porewater of interconnected wetlands were more similar to each other than to those of wetlands located farther away. Porewater and surface water in a restored wetland showed similar multi-element characteristics to natural wetlands. In contrast, depressional wetlands connected by seeps along a deactivated drain-tile path and a grazed wetland showed distinctly different multi-element characteristics compared to other wetlands sampled. Our findings confirm that the multi-element fingerprinting method can be useful for assessing hydro-chemical connectivity across the landscape, and indicate that element concentrations are not only affected by land use, but also by hydrological characteristics.


Farm Programs, Payments And Prospects, Bradley D. Lubben Oct 2018

Farm Programs, Payments And Prospects, Bradley D. Lubben

Cornhusker Economics

The USDA Farm Service Agency (FSA) began issuing payments to producers in October for Price Loss Coverage (PLC) and Agriculture Risk Coverage (ARC) programs for the 2017 crop year. While these farm program payments had provided substantial cash flow to help buffer falling market price and farm income projections in the past three years, the current programs will provide relatively little cash flow for now and for the coming year. Only the ad hoc trade assistance payments and the outlook for new farm programs and decisions in 2019 may provide potential relief from the current outlook.


Applying Interconnected Game Theory To Analyze Transboundary Waters: A Case Study Of The Kura-Araks Basin, Marianna Khachaturyan, Karina Schoengold Oct 2018

Applying Interconnected Game Theory To Analyze Transboundary Waters: A Case Study Of The Kura-Araks Basin, Marianna Khachaturyan, Karina Schoengold

Cornhusker Economics

A number of environmental problems are international in nature, including many water management issues. Rivers, for example, do not recognize political boundaries. Therefore, pollution generated in one country can affect neighboring countries, while water extraction in an upstream country can affect water flow and water availability in a downstream country. The situation creates an interdependency among countries, which might lead to disputes over the management of transboundary water. Therefore, coordination among the countries is necessary for effective management of these transboundary resources.

The focus of a recently published study (Khachaturyan and Schoengold, 2018) is the transboundary Kura-Araks Basin (see Figure …

Farm Location Influence On The Optimal Crop Insurance And Pre-Harvest Hedging Level, Cory Walters Sep 2018

Farm Location Influence On The Optimal Crop Insurance And Pre-Harvest Hedging Level, Cory Walters

Cornhusker Economics

Improving farm financial health can come from improving the understanding of the market forces influencing the optimal crop insurance contract and preharvest hedging risk management tools. The biggest challenge for farmers is the difficulty of assessing risk since experiencing risk, is by default, rare. Additionally, farmers receive advice about which crop insurance plan they should purchase or how much pre-harvest hedging they should do from sources, such as farm magazines, that likely do not consider the differences in individual risk exposure. Following the advice of such sources could result in producers being inadvertently exposed to more risk. A producer’s location …


The Corn/Soybean Rotation And Profitability, Matt Stockton, Devin Broadhead Sep 2018

The Corn/Soybean Rotation And Profitability, Matt Stockton, Devin Broadhead

Cornhusker Economics

One of the most basic questions farmers must answer on an annual basis is what to plant. In some cases this is simply a choice among cultivars in others it is a choice among different crop types. In Nebraska the choice may vary considerably since many different crop types are grown. This discussion focuses on the factors that affect profitability, which are created by both biology and economics, and how that might be used to make the best crop rotation selection between corn and soybean cropping systems.


Searching Images And The Meaning Of Alarm Calls, Alan B. Bond Sep 2018

Searching Images And The Meaning Of Alarm Calls, Alan B. Bond

Alan Bond Publications

The snake alarm call of Japanese tits prompts nesting adults to search for and mob the reptile until it is driven away. From playback experiments, Suzuki (2018) has inferred that the call provides an associative cue, evoking a searching image of the salient visual features of the predator—a novel approach to exploring visual attention and vocal communication in the wild.


Importance Of Being Digital Ready – What Does That Mean?, Charlotte Narjes Sep 2018

Importance Of Being Digital Ready – What Does That Mean?, Charlotte Narjes

Cornhusker Economics

Communities often determine if they are digital ready on whether or not high speed internet is available. The conversation then focuses on who has high speed internet and who does not. Hence, the divide. High speed internet is an important factor on whether or not a community can be competitive in a global market. But, it is not the only digital-ready factor necessary to compete in a global economy. One challenge of focusing on the divide is that assumptions are made that individuals do not have skills in rural areas to use technology and, that these rural residents may not …

A Model For Farmer Support In Zimbabwe – Opportunity For Change, Brierly Kuhudzayi, Daniela Mettos

Cornhusker Economics

Community development refers to the collective action of a group of people to improve their quality of life or to fix a problem they face. It involves active participation by the people facing the problem. Input subsidy programs (ISPs) are commonly used in Sub-Saharan Africa as a strategy to achieve several development goals. They generally aim to improve the lives of poor subsistence-level farmers, improve agricultural output, and stimulate the economy. However, ISPs are not technically a community development tool because they are typically centrally planned and top-down in nature.

Across several meta-analyses, MAOA-uVNTR genotype has been associated with an increased risk for antisocial behavior among males who experienced early life adversity. Subsequently, early life stress and genetic susceptibility may have long-term effects on stress sensitivity later in life. In support of this assumption, a recent study found evidence, in two independent samples, for a three-way interaction effect (cG × E × E) such that proximate stress was found to moderate the interactive effect of MAOA-uVNTR and distal stress on crime and delinquency among males. In light of recent developments in cG × E research, we attempted to …
