Maintaining And Improving Irrigation Application Uniformity In Sprinkler And Drip Systems, Burdette Barker, Sheridan Stewart, Mark Nelson
All Current Publications
The goal of most irrigation system design and management is to provide all plants in an irrigated area with equal access to water. Ideally, each plant should receive the exact amount of water it needs. If a field needs 1 inch of water for irrigation, all parts of the field should receive exactly that. The reality is not so perfect. It is practically impossible to apply the same quantity of water to all plants in an irrigated area, plot, or field. In other words, all irrigation systems have some nonuniformities in the water delivered. Instead of designing and managing irrigation …

Suggested Vegetable Planting Dates: Grand And San Juan Counties, Reagan Wytsalucy, Cory Farnsworth, Dan Drost
All Current Publications
This fact sheet addresses vegetable planting dates in Grand and San Juan counties in Utah. “When should I plant?” and “What should I plant?” are two of the more common questions received from Utah gardeners. To answer the “When” question, you need to know something about the climate where you live. Vegetable plants vary in their response to temperature and are grouped by how they cope with cold or hot conditions. There are four (4) vegetable groups, which include the hardy, half-hardy, tender, or very tender crops. These groups are also referred to as the cool season (hardy or half-hardy) …

Salt is an important factor in plant and soil management. Excessive salt concentrations in soil can cause water to be less available to plants because of the osmotic forces of salt in the soil water. Excessive concentrations of different ions can also be toxic to plants. In agricultural soils and irrigation water, salts are typically described in two ways: (1) total salt concentration or salinity, and (2) sodicity, or the concentration of sodium relative to other cations (positively charged atoms or compounds). Understanding the effect of both total salinity and sodicity on plants and soils, along with management and reclamation …

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 …

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 …

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 …

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

Aversion Properties Of Retrorsine, Retrorsine Nitrogen Oxide And Frosted Senecio Latifolius, Leendert D. Snyman
Poisonous Plant Research (PPR)
Two pilot trials, investigating the aversive properties of retrorsine and retrorsine nitrogen oxide and that of frosted Senecio latifolius, were executed. Retrorsine and retrorsine-NO (the toxic principles of Senecio retrorsus), unlke sceleratine-NO (the toxic principle of another hepatotoxic pyrrolizidine alkaloid containing plant, namely S. latifolius), were not capable of establishing aversion when given to a sheep. Frosted S. latifolius given to a sheep also did not induce aversion. However, a sheep averted to S. latifolius (non-frosted) refused eating frosted S. latifolius.

Managing Soil Ph For Crop Production In Calcareous-Alkaline Soil, Cody Zesiger, Jody Gale, Matt Yost, Grant Cardon
All Current Publications
In semiarid soils of the Western U.S., altering soil pH is not easily accomplished nor straightforward. Utah’s soil pH range can be 1,000 times more acidic or alkaline than neutral (7.0) pH soils. In semiarid regions, typical high-pH soils are also calcareous, meaning there is a large amount of solid calcium carbonate (lime) in the soil. When soil-acidifying amendments are added to these soils, the lime dissolves and counteracts any of the applied soil-acidifying amendments. This fact sheet explains how to identify whether crop symptoms are related to soil pH, how to perform an in-field test for soil pH buffering …
Isolation Of The Toxic Principle Of Senecio Latifolius By Means Of The Sensory Receptors Of Sheep, Leendert D. Snyman
Isolation Of The Toxic Principle Of Senecio Latifolius By Means Of The Sensory Receptors Of Sheep, Leendert D. Snyman
Poisonous Plant Research (PPR)
The aversive substance of Senecio latifolius was isolated by means of the sensory receptors of sheep averted to S. latifolius. Chemical fractions refused due to the presence of the aversive substance sensed by the sheep were fractionated until a purified substance had been isolated. Nuclear magnetic resonance (NMR) analysis of the purified substance showed it to be sceleratine nitrogen oxide, the toxic principle of S. latifolius.

Irrigation uniformity can be reduced by wheel track rutting because of tire slippage (Meyer & Hoffman, 1983). These impacts can result in costly repairs to equipment, including gear boxes (about $700 each) and center-drive motors (about $550 each), or hydraulic pumps and motors on certain makes of pivot. Labor and crop damage associated with freeing or repairing a pivot or caused by downtime can also be a great expense to the farmer. This guide covers different strategies for managing wheel track rutting for center pivots and lateral-move systems.

Predicting Current And Future Alfalfa Hay Prices In Seven Western States, Dillon M. Feuz, Ryan Larsen
All Current Publications
Alfalfa hay prices were analyzed in the seven western states. Utah hay prices were most closely correlated with Oregon and Washington hay prices. Corn grain, feeder cattle, and milk prices all impact alfalfa hay prices, as do the May 1 USDA hay stocks and alfalfa hay exports. Using these price relationships, an alfalfa hay pricing tool was developed to predict hay prices up to 9 months into the future.
