Cache Junction Farm

Animal Science Farm Field and Barns

History

The Cache Junction Farm is among our newest facilities. Established in 2003, it is the site of commercial crop production, including alfalfa and grass hay used to feed university animals, seed peas for a seed company, as well as wheat and pinto beans.

Research Topics

Research underway at the Cache Junction Farm includes entomology studies of cereal leaf beetle and other pests, weed control experiments and barley variety trials. USDA Agricultural Research Service scientists are also using space at the farm for bee research and alfalfa trials. Research is also taking place above the farm as water engineers test methods of aerial mapping and ground imaging and the USU-affiliated Space Dynamics Laboratory operates a ground-based LIDAR (Light Detection and Ranging) instrument to study the atmosphere.

Breeding and evaluation of sustainable winter barley cultivars for feed and malting

Project Lead: David Hole

As water demands increase, and available irrigation water supplies stay constant or decline in Utah, barley production systems will need to adapt to earlier maturity and to make use of winter precipitation and early spring moisture.Winter barley is poised to allow such a shift, as it can mature earlier and allow growers to focus equipment, labor, and water resources on other crops, such as hay, later in the summer season. Because both environmental stresses and diseases and insects differ markedly between geographical areas, it is important to develop cultivars that perform particularly well in a given production area. In addition, as management practices change to become more sustainable, plant breeding must continually shift emphases to develop adapted material for current and future production systems. Food safety and food nutrition requirements also change with increased knowledge, and plant breeding is responsible for providing cultivars to meet the needs of increasingly more sophisticated consumers and allied industries. Plant breeders are tasked with development of these improved cultivars to meet the agronomic needs of local producers; cereal chemistry and rheology needs of the industries that processes these grains; and safety and nutrition needs of the consumers who purchase and feed their families with them. In addition to the direct research, the value of including undergraduate and graduate students as part of building and maintaining capacity in plant breeding and genetics should not be undervalued. Conventional and genomic breeding of improved cultivars will result in new cultivars released for acceptance by stakeholders including farmers and the feed and malting industries.

Development and testing wheat cultivars and germplasm for changing environments

Project Lead: David Hole

Plant breeding is a long-term research project. Because both biotic and abiotic stresses differ markedly between geographical areas, genotype by environment interactions can be exploited to develop cultivars that perform particularly well in a given production area. In addition, as management practices change to become more sustainable, plant breeding must continually shift emphases to develop adapted material for current and future production systems. Food safety and food nutrition requirements also change with increased knowledge, and plant breeding is responsible for providing cultivars to meet the needs of increasingly more sophisticated consumers and allied industries. Plant breeders are tasked with development of these improved cultivars to meet the agronomic needs of local producers; cereal chemistry and rheology needs of the industries that processes these grains; and safety and nutrition needs of the consumers who purchase and feed their families with them. In addition to the direct research, the value of including undergraduate and graduate students as part of building and maintaining capacity in plant breeding and genetics should not be undervalued. Long range sustainability of U.S. agriculture will be enhanced by providing breeders with both the germplasm and the reliable selection tools to allow incorporation of resistance genes for common bunt and dwarf bunt in adapted cultivars. This project will also incorporate training field-based breeders by integrating undergraduate and graduate students funded by this project into ongoing productive plant breeding programs in Utah. As race changes occur in the disease organisms, identification of new resistance genes in critical. Previous screening of winter wheat accessions in the National Plant Germplasm System has identified a number of extremely resistant lines that contain previously unidentified and un-utilized resistance. We do not know, however, if these lines incorporate new combinations of previously identified genes, or if they contain novel, previously unidentified, genes. It will be vital to characterize novel genes for resistance that are available in the National Small Grains Collection (part of the National Plant Germplasm Collection). It is important to continue screening the National Small Grains Collection for winter wheat accessions to identify novel sources of resistance to both common bunt and dwarf bunt.

A Framework to Develop New Approaches for Managing Invasive Plants in Natural and Agricultural Systems of UTAH

Project Lead: Steve Young

"One of the biggest and most complex problems facing society today is the issue of invasive plants. While the general public may not view invasive plants as a threat or even a problem, their importance is well documented scientifically and their impacts on society (health risks), economies (production systems), and the environment (loss of diversity) are staggering. Invasive plants can establish in diverse environments, and, with the increase in human mobility, they are no longer restricted to isolated pockets in remote locations. Cheatgrass in rangelands, purple loosestrife in wetlands, and tamarisk in riparian areas are examples of invasive plants that are common to Utah and can be found in monocultures and patches covering a few to many thousands of acres. Other invasive plants, such as kochia, field bindweed, and prickly lettuce, have developed a tolerance to single tactic approaches in agro-ecosystems. Invasive plants can reduce water flow, alter fire regimes, and limit yields while costing thousands of dollars in control and lost productivity.

While the effects of invasive plants can be devastating, the approach taken for management is often without considering the underlying mechanisms; this prevents successful control of these species at larger scales. Invasive plants continue to consume more area, which threaten the sustainability of plant, animal, insect, soil nutrient, and - ultimately - human systems. The goal of my project is to understand the underlying mechanisms of how and why invasive plants exist, where they exist, and the conditions in which they exist using an invasion factor framework. As new knowledge is generated, its application to natural- and agro-ecosystems will allow for the development of more sustainable strategies for managing and maintaining important natural resources. Through plant competition studies, my project will be addressing the factors of ecosystem resistance, invader fitness, and climate dynamics that are fundamental in limiting invasion success, thus helping to 1) improve the quality of life for Utahns and 2) sustain the state’s natural and agro-ecosystems.

Research on global climate change has predicted that extreme weather events will increase in the continental U.S. within the next 100 years. While much research has focused on plants important to agricultural production and rangeland restoration, invasive plants have received little attention. In order to better understand the mechanisms that will allow invasive plants to successfully establish in novel or climate-altered ecosystems of the future, it is critical to study the phenotypic traits of invasive plants as they evolve under extreme climatic events and develop drought-resistant populations. It has been postulated that invasive plants exhibit greater climatic tolerance ranges in invaded habitats than in their native habitats. For extreme events such as drought, a combination of both phenotypic and genetic adaptation could be equally important for invasive plants to survive and proliferate. By isolating drought-resistant individuals in manipulative experiments, traits can be quantified for a range of invasive plants. Ultimately, this new area of research will provide a greater understanding of how invasive plants differ in their adaptation to habitats at the molecular to population scale.

Within the last decade, an increasingly critical question is being asked regarding agriculture, which is, ""Can we sustain (increase) production with our current management practices?” We are now faced with the reality that our current production systems cannot support the expected increase in world population by the year 2050. With the increases in herbicide resistant weeds, off-target movement of pesticides, organic production, threats of widespread disease and pest outbreaks, and public concern for safe food supplies, in addition to the abovementioned onset of a warmer, drier climate, it would be unwise to ignore the importance of developing new and/or enhancing current ecologically-based management strategies to lower inputs and incorporate advanced computer technologies, such as robotics, sensors, and guidance and communication systems. My project is part of a group that includes ecologists, engineers and agronomists working with computer scientists to address the complexities of natural and agro-ecosystems with regard to invasive plants.

A more holistic approach is needed for managing natural- and agro-ecosystems where invasive plants exist and threaten habitats, natural resources, and livelihoods. By using a framework that addresses the key factors contributing to the successful establishment of invasive plants, a research program can be built that has a clear mission and leads to sustainable management solutions. In combination with educational endeavors, such as a short course for practitioners, research could be expanded and shared with stakeholders, land managers, and professionals from Utah and neighboring regions through a first-ever, Invasive Plant Research and Training Center at USU. No other state is like Utah with the diversity of invasive plants in both natural and agro-ecosystems and facing climate change and a growing urban population. A Center focused specifically on invasive plants through research and training would be able to address immediate and future needs of our society by producing and disseminating new knowledge on the science of invasive plants."

Assessing changing precipitation effects on dryland agriculture production

Project Lead: Andrew Kulmatiski

"As the atmosphere warms over much of the globe, precipitation events are predicted to become fewer but larger. This increasing precipitation intensity is expected to be a major driver of changes in terrestrial ecosystems in the coming decades. Yet, only two multi-year experiments testing the effects of increasing precipitation intensity have been performed anywhere in the world. As a result, little is known about how crops of the western US will respond to increasing precipitation intensity. Here we propose to test the effects of increased precipitation intensity on dryland agriculture in Cache Valley, Utah, USA.

In addition to providing an experimental test, results from the proposed research will be used to inform a broader understanding of precipitation intensity effects on plant growth, fire regimes and feedbacks between the biosphere and atmosphere. This will be accomplished by using experimental data to parameterize and test ecohydrological models. These models can then be used to help lead the selection and development of dryland crop species that are best adapted to future climate conditions. This research, therefore, is expected to reduce dryland crop variability and increase dryland crop profitability. Results will also be a part of a comprehensive experiment that will assess precipitation effects across a wide range of ecosystems common to the intermountain west and inasmuch will help farmers, ranchers and foresters anticipate and manage for changing climate conditions."

Legume-Finished Beef: Achieving Current Production with Greater Environmental, Economic and Social Sustainability

Project Lead: Jennifer MacAdam

Feeding cattle in feedlots is efficient, but problematic because feed yards produce concentrated ammonia emissions and animals are routinely treated with antibiotics and hormones that can contaminate the environment. We propose the use of multiple nutritive forages that contain bioactive natural plant products (e.g., tannins) at pasture to mitigate this problem. Our goal is to create a multidisciplinary, multi-state regional research and outreach team along with an advisory panel to collect data on animal production, environmental impact and perceived customer value of the proposed new system. This grant will allow taking the critical steps of developing a regional partnership and plan for a Coordinated Agricultural Project that integrates high-quality forages containing bioactive natural plant products into beef production; exploring consumer interest in the approach; and collecting critical preliminary data on winter feeding beef cows and calves using the preserved proposed forages. The transformative new system proposed will eliminate grain feeding and reduce environmental impacts relative to feed yards while maintaining beef production levels and enhancing the quality of the product.

Irrigated Perennial Legume Pastures for Dairy and Beef Production in the Intermountain West

Project Lead: Jennifer MacAdam

The goal of this project is to improve the economic and environmental sustainability of beef production in Utah and the Mountain West region. This work addresses concerns that beef consumers have about the welfare of cattle finished in feedlots and the implications for their own health when feedlot cattle routinely consume subtherapeutic doses of antibiotics and hormones to promote growth or offset unhealthy feedlot conditions. This research project also addresses environmental and social justice issues, such as the feeding of grain to ruminants, where feed conversion rates are extremely poor, the soil erosion and nitrogen fertilization associated with this annual cereal grain production, the generation of greenhouse gases that accrue to agriculture from the transportation of cattle and grain to central feedlot locations on the Great Plains, the concentration of nutrient and antibiotic pollutants in the air and water close to feedlots; and the economic shift of profits from cattle largely raised by small producers in the West to feedlot owners and meat processors in other regions. Finishing beef cattle on pastures and marketing it within the western region to consumers interested in a leaner but still juicy and good-tasting product would create a more-sustainable alternative to conventional beef production.

Employing Forage Legumes to Improve the Sustainability of Ruminant Production

Project Lead: Jennifer MacAdam

The long-term goal of this project is to improve the profitability of Utah livestock producers, reduce the negative environmental impact of ruminant production and increase the food security of residents of Utah and the northern Mountain West. Beef and dairy production account for a large proportion of Utah's agricultural output. Feed costs are the most expensive input for livestock operations, and the efficiency of feed use can have a significant effect on both the profitability of a livestock operation and its environmental impact. Western livestock producers can increase the productivity of privately owned land by increasing the use of legumes, particularly those that can be grazed without fear of bloat. They can also increase the profitability of livestock production by marketing natural or organic meat directly to the high concentration of urban residents and restaurants.
