The Importance Of Strategic Planning For Farmers And Ranchers, Larry Van Tassell Feb 2024

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.

Oystershell Scale (Hemiptera: Diaspididae) Population Growth, Spread, And Phenology On Aspen In Arizona, Usa, Connor D. Crouch, Richard W. Hofstetter, Amanda M. Grady, Nylah N.S. Edwards, Kristen M. Waring

Aspen Bibliography

Oystershell scale (OSS; Lepidosaphes ulmi L.) is an invasive insect that threatens sustainability of aspen (Populus tremuloides Michx.) in the southwestern United States. OSS invasions have created challenges for land managers tasked with maintaining healthy aspen ecosystems for the ecological, economic, and aesthetic benefits they provide. Active management is required to suppress OSS populations and mitigate damage to aspen ecosystems, but before management strategies can be implemented, critical knowledge gaps about OSS biology and ecology must be filled. This study sought to fill these gaps by addressing 3 questions: (i) What is the short-term rate of aspen mortality in …

Impacts Of Climate Change And Agricultural Practices On Nitrogen Processes, Genes, And Soil Nitrous Oxide Emissions: A Quantitative Review Of Meta-Analyses, Dafeng Hui, Avedananda Ray, Lovish Kasrija, Jaekedah Christian Feb 2024

Impacts Of Climate Change And Agricultural Practices On Nitrogen Processes, Genes, And Soil Nitrous Oxide Emissions: A Quantitative Review Of Meta-Analyses, Dafeng Hui, Avedananda Ray, Lovish Kasrija, Jaekedah Christian

Biology Faculty Research

Microbial-driven processes, including nitrification and denitrification closely related to soil nitrous oxide (N2O) production, are orchestrated by a network of enzymes and genes such as amoA genes from ammonia-oxidizing bacteria (AOB) and archaea (AOA), narG (nitrate reductase), nirS and nirK (nitrite reductase), and nosZ (N2O reductase). However, how climatic factors and agricultural practices could influence these genes and processes and, consequently, soil N2O emissions remain unclear. In this comprehensive review, we quantitatively assessed the effects of these factors on nitrogen processes and soil N2O emissions using mega-analysis (i.e., meta-meta-analysis). The results showed that global warming increased soil nitrification and denitrification …


Pile Burning After Conifer Removal From Aspen Stands Affects Tree Mortality, Regeneration, And Understory Recovery, John-Pascal Berrill, Christa M. Dagley, Yoon G. Kim, J. Morgan Varner Feb 2024

Pile Burning After Conifer Removal From Aspen Stands Affects Tree Mortality, Regeneration, And Understory Recovery, John-Pascal Berrill, Christa M. Dagley, Yoon G. Kim, J. Morgan Varner

Aspen Bibliography

Quaking aspen (Populus tremuloides Michx.) stands throughout the western United States provide valuable ecosystem services but can be lost via succession from aspen to conifer. Forest managers are cutting conifers, but disposal of cut wood can be challenging in remote or sensitive areas. Piling and burning is being tested within aspen stands but ecosystem responses to this treatment are understudied. We assessed aspen tree mortality, tree regeneration, and understory vegetation after forest restoration thinning followed by pile burning in seven aspen-conifer stands around Lake Tahoe, California and Nevada, USA. Pile burning was conducted after cut wood had dried (1.5–7.5 …

Studying The Genes And Conditions That Influence Root Development, Tessa Holtkamp, Hannah Ordonez Webb Jan 2024

Studying The Genes And Conditions That Influence Root Development, Tessa Holtkamp, Hannah Ordonez Webb

Undergraduate Research Symposium

Root development in plants is essential for their survival and understanding how hormones influence their development can explain how plants grow under different circumstances. Researching how Indole-3-butyric acid (IBA), a hormone that induces root production, affects the plant model Arabidopsis thaliana helps explain the hormone's effect in agricultural crop systems. To understand root pathways, we performed assays on mutant lines of Arabidopsis by growing plants on varying concentrations of IBA. For wild-type and mutant lines, phenotyping experiments like branching of roots, lengths of stems, and root length were conducted along with PCR and restriction digest genotyping experiments to compare their …


Slight Cost Of Production Changes Noted In The 2024 Nebraska Crop Enterprise Budgets, Glennis Mcmclure Jan 2024

Slight Cost Of Production Changes Noted In The 2024 Nebraska Crop Enterprise Budgets, Glennis Mcmclure

Cornhusker Economics

The Nebraska crop budgets are available for the 2024 production season. The 84 enterprise budgets prepared in the October 2023 timeframe use input prices collected as of that time. Overall, estimates reflect slight cost of production decreases in the budgets when compared to the 2023 cost estimates. For 2024, the main drivers of cost decreases are due to decreased fuel and fertilizer costs. In some cases, pesticide costs decreased, yet for some of those products, prices increased. Seed and interest costs have increased for 2024 adding to cash expenses, while land opportunity costs and depreciation costs have continued to rise …

Aspen And Spruce Densities Affect Tree Size, Future Stand Volume, And Aboveground Carbon Following Precommercial Thinning, Philip G. Comeau, Mike Bokalo Jan 2024

Aspen And Spruce Densities Affect Tree Size, Future Stand Volume, And Aboveground Carbon Following Precommercial Thinning, Philip G. Comeau, Mike Bokalo

Aspen Bibliography

Data collected over a 30-year period from an experiment replicated across 21 locations in western Canada are used to explore the effects of precommercial thinning of trembling aspen to a range of densities in combination with three initial white spruce densities on tree growth and stand dynamics. Increasing differentiation amongst the 15 treatments was observed with age after thinning for both spruce and aspen responses. Spruce height and diameter declined with increasing aspen density. At age 10 spruce diameter with no aspen was 1.5× that of spruce in unthinned while it was 2.6× that of spruce in unthinned at age …

Tracing The Maternal Line In Glacial-Interglacial Migrations Of Populus Tremuloides: Finding Trees For Future Sustainable Forests By Searching In The Past, Luke R. Tembrock, Frida A. Zink, Guozhe Zhang, Andrea Schuhmann, Cuihua Gu, Zhiqiang Wu

Aspen Bibliography

Maintaining and planting sustainable forests is fundamental in perpetuating the essential functions of these ecosystems. A central aspect of managing forests for future resilience is the consideration of past migration and evolution of trees using genetic and genomic data to ensure that functionally appropriate diversity is conserved and utilized. In our study, we generated and compared genetic and genomic data from the plastome to better understand phylogeography and molecular evolution in the tree species Populus tremuloides (aspen). With these analyses, we found evidence of divergence and migration between northern and southern sites. Additionally, evidence of deep incomplete plastome sorting across …


Deficit Irrigation Of Pastures, Matt Yost, Clara Anderson, Niel Allen, Burdette Barker, Melanie Heaton, Justin Wyatt Clawson, Earl Creech Jan 2024

Deficit Irrigation Of Pastures, Matt Yost, Clara Anderson, Niel Allen, Burdette Barker, Melanie Heaton, Justin Wyatt Clawson, Earl Creech

All Current Publications

Deficit irrigation is any irrigation level that does not meet the crop’s full evapotranspiration (ET) demand, meaning evaporation from plant and soil surface and transpiration through plant growth. This strategy is often a last resort for optimizing water use as opposed to those that will not limit production. However, deficit irrigation is often necessary in parts of Utah due to drought or inadequate water supplies. This was especially true in 2021–2022 due to record droughts. Deficit irrigation strategies for pastures have been developed, but they have yet to be compared and evaluated in Utah. This fact sheet summarizes 6 years …

Are Too Many Or Too Few Babies Being Born?, Wesley Peterson Jan 2024

Are Too Many Or Too Few Babies Being Born?, Wesley Peterson

Cornhusker Economics

An additional 1.8 billion people will be added to the world’s population by 2050. At the same time, average incomes are likely to rise. Data from the Groningen Growth and Development Center suggest that average real (inflation-adjusted) GDP per capita increased by a factor of fifteen between 1820 and 2018 and World Bank data indicate that real per capita GDP more than tripled over the past 62 years. It is likely that these trends will continue and there will be more people with higher average incomes in the future straining global food systems and natural resources. Slower population growth rates …

Crop Classification In South Korea For Multitemporal Planetscope Imagery Using Sfc-Densenet-Am, Seonkyeong Seong, Anjin Chang, Junsang Mo, Sangil Na, Hoyong Ahn, Jaehong Oh, Jaewan Choi

Agricultural and Environmental Sciences Faculty Research

In this manuscript, a new methodology based on a deep learning model using a Siamese network and attention module was proposed to classify crop cultivation areas, such as onion and garlic, from multitemporal PlanetScope images in South Korea. To consider the seasonal characteristics of crops in the model, training data were constructed from multitemporal satellite images. It was generated using PlanetScope satellite imagery from January and April, corresponding to the seasonal growth period of onion and garlic, in South Korea. Image patches were generated by considering the ratio of crops to minimize the influence of imbalanced data in the training …

Plum Curculio (Conotrachelus Nenuphar), Kate V. Richardson, Marion Murray Jan 2024

Plum Curculio (Conotrachelus Nenuphar), Kate V. Richardson, Marion Murray

All Current Publications

Plum curculio is a brown weevil (beetle with a snout) native to eastern North America, where it is a major pest of pome and stone fruits. It was detected in Box Elder County, Utah, in the early 1980s, and this population remains the only known infestation in western North America, where it is occasionally found in residential and wild fruit trees. Plum curculio is a quarantine pest in western North America (U.S. and Canada), and fruit grown in infested counties is restricted from being exported. Thus, it is a threat to Utah’s fruit industry and requires ongoing monitoring and management …

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Managing annual row crops on marginally productive croplands can be environmentally unsustainable and result in variable economic returns. Incorporating perennial bioenergy feedstocks into marginally productive cropland can engender ecosystem services and enhance climate resiliency while also diversifying farm incomes. We use one of the oldest bioenergy-specific field experiments in North America to evaluate economically and environmentally sustainable management practices for growing perennial grasses on marginal cropland. This long-term field trial called 9804 was established in 1998 in eastern Nebraska and compared the productivity and sustainability of corn (Zea mays L.)—both corn grain and corn stover—and switchgrass (Panicum virgatum …
