Aspen Soils Retain More Dissolved Organic Carbon Than Conifer Soils In A Sorption Experiment, Antra Boča, Astrid R. Jacobson, Helga Van Miegroet
Aspen Soils Retain More Dissolved Organic Carbon Than Conifer Soils In A Sorption Experiment, Antra Boča, Astrid R. Jacobson, Helga Van Miegroet
Aspen Bibliography
The effect tree species have on soil organic carbon (SOC) has been hotly debated but, so far, few clear patterns have emerged. One example of a differing tree species effect on SOC are aspen forests in North America, which have been found to have more stable SOC than adjacent conifer forest stands. An important source for the formation of stable organo-mineral complexes in soil is dissolved organic carbon (DOC). DOC concentrations in mineral soil are often higher under the thick O-horizons of conifer forests than under aspen forests, but this does not correspond to more stable mineral SOC. This suggests …

Three-Lined Potato Beetle, Nick Volesky
All Current Publications
The three-lined potato beetle (Lema daturaphila) is part of the Chrysomelidae family of beetles. It originates from North and Central America but has since been reported causing economic damage to crops worldwide, such as the cape gooseberry in South Africa and potato in Australia. Though uncommon, the three-lined potato beetle has previously been documented in Utah. In August 2020, it was closely observed causing economic damage in tomatillo production on a commercial vegetable farm in rural Box Elder County, Utah. This fact sheet reviews three-lined potato beetle identification, life cycle, and look-alikes, damage, and management.
Row Covers, Nick Volesky, Katherine Wagner
Row Covers, Nick Volesky, Katherine Wagner
All Current Publications
In agricultural use, a row cover is a transparent or semitransparent material that is used over crops (typically vegetables) for a variety of purposes. As an integrated pest management tool, row covers act as a physical barrier that prevents the movement of pests such as insects, birds, and mammals, to host plants. This form of management is popular in organic production to avoid chemical application. Row covers are also used to shield crops from environmental factors like cold or hot temperatures, and wind. Commonly used methods of application include floating row covers, hoop-supported row covers (also called low tunnels), and …
Managing Suckers Around Fruit Trees, Samuel Johnson, Teryl Roper, Xin Dai
Managing Suckers Around Fruit Trees, Samuel Johnson, Teryl Roper, Xin Dai
All Current Publications
Many types of fruit trees produce suckers around the base of the tree. Crown suckers arise in the area immediately surrounding the tree trunk (Photo 1), and root suckers can arise from roots further away from the trunk. Not only are suckers around trees unsightly, but they can also harbor insect pests like wooly apple aphid and provide points of entry for diseases like fire blight. If suckers are profuse, they interfere with in-row weed management and can absorb systemic herbicides such as glyphosate. Some rootstocks used for fruit trees such as M.7 for apples and Mazzard for cherries are …

Simulated Fire Behavior And Fine-Scale Forest Structure Following Conifer Removal In Aspen-Conifer Forests In The Lake Tahoe Basin, Usa, Justin P. Ziegler, Chad M. Hoffman, Brandon M. Collins, Jonathan W. Long, Christa M. Dagley, William Mell
Aspen Bibliography
Quaking aspen is found in western forests of the United States and is currently at risk of loss due to conifer competition at within-stand scales. Wildfires in these forests are impactful owing to conifer infilling during prolonged fire suppression post-Euro-American settlement. Here, restoration cuttings seek to impact wildfire behavior and aspen growing conditions. In this study, we explored how actual and hypothetical cuttings with a range of conifer removal intensity altered surface fuel and overstory structure at stand and fine scales. We then simulated wildfires, examining fire behavior and effects on post-fire forest structures around aspen trees. We found that …

Drought- Conditioning Of Quaking Aspen (Populus Tremuloides Michx.) Seedlings During Nursery Production Modifies Seedling Anatomy And Physiology, Joshua L. Sloan, Owen T. Burney, Jeremiah R. Pinto
Aspen Bibliography
In the western US, quaking aspen (Populus tremuloides Michx.) regenerates primarily by root suckers after disturbances such as low to moderate severity fires. Planting aspen seedlings grown from seed may provide a mechanism to improve restoration success and genetic diversity on severely disturbed sites. However, few studies have examined the use of container-grown aspen seedlings for restoration purposes from both the outplanting and nursery production perspective. Thus, the purpose of this novel study was to examine how alterations in irrigation levels during nursery production across three seed sources would impact seedling performance attributes on harsh, dry outplanting sites. Irrigation …

Nutrient Management Strategies For Organic Vegetable Production, Emma Jones, Daniela Barrera, Jennifer R. Reeve, Dan Drost
All Current Publications
Organic vegetable production can be profitable for growers in Utah looking to supply local markets. Much of Utah has short growing seasons (<150 days frost-free) with hot, dry summers and cold winters. Organic growers must work within these constraints to generate sufficient soil fertility using cover crops, composts, and targeted use of commercial organic fertilizers. This fact sheet explores nutrient management techniques used at the Utah State University (USU) Student Organic Farm (Student Farm) located in Cache County. In operation since 2008, the Student Farm was certified organic in 2011.

Nitrogen Fertilizer Guide For First-Year Small Grains Following Alfalfa, Matt Yost, Collin Pound, Earl Creech, Grant Cardon, Jody Gale, Michael Pace, Boyd Kitchen, Steve Price, Kevin Heaton, Mark Nelson, Trent Wilde, Katie Russell
All Current Publications
Nitrogen (N) fertilizer is one of the most expensive crop inputs. It is an essential nutrient for most crops and often increases yield more than any other nutrient. Small grains are no exception. Alfalfa is the dominant crop in Utah in terms of area and gross sales, and as a nitrogen-fixing legume, it does not require nitrogen fertilizer. When terminated, alfalfa usually leaves a lot of nitrogen in the soil for subsequent crops. The amount of nitrogen that it supplies to following crops has been termed the “alfalfa N credit.” In many cases, this credit can be up to 300 …
Aspen Next Generation: Conversations From Southern Colorado And Northern New Mexico, Dan Binkley, Bill Romme
Aspen Next Generation: Conversations From Southern Colorado And Northern New Mexico, Dan Binkley, Bill Romme
Aspen Bibliography
Aspen trees and forests are especially important in the Rocky Mountains. Aspens add beauty to landscapes, foster high diversity and productivity of understory plants, provide for the habitat needs of many species of animals, and moderate fire behavior. There is a perception that aspen trees and stands are not regenerating well in southern Colorado and northern New Mexico; cohorts of trees younger than a few decades are scarce, at least in some areas. The next generation of aspen in the southern Rockies will be influenced by land use decisions, including harvesting, fire policy and management, and browsing by livestock and …

Genomic Insights Into Speciation History And Local Adaptation Of An Alpine Aspen In The Qinghai–Tibet Plateau And Adjacent Highlands, Jia-Lang Li, Lin-Ling Zhong, Jing Wang, Tao Ma, Kang-Shan Mao, Lei Zhang
Aspen Bibliography
Natural selection serves as an important agent to drive and maintain interspecific divergence. Populus rotundifolia Griff. is an alpine aspen species that mainly occurs in the Qinghai–Tibet Plateau (QTP) and adjacent highlands, whereas its sister species, P. davidiana Dode, is distributed across southwest and central to northeast China in much lower altitude regions. In this study, we collected genome resequencing data of 53 P. rotundifolia and 42 P. davidiana individuals across their natural distribution regions. Our population genomic data suggest that the two species are well delimitated in the allopatric regions, but with hybrid zones in their adjacent region in …

Long-Term Soil Productivity Study: 25-Year Vegetation Response To Varying Degrees Of Disturbance In Aspen-Dominated Forest Spanning The Upper Lake States, Miranda T. Curzon, Brian J. Palik, Anthony W. D'Amato, Julia Schwager
Aspen Bibliography
Installations of the Long-Term Soil Productivity Study were established in northern Minnesota and Michigan at the Chippewa, Ottawa, and Huron-Manistee National Forests (NFs) in the early 1990s and have since provided a wealth of data for assessing the response of aspen-dominated forest ecosystems to varying levels of organic matter removal and soil compaction. An assessment of 25-year standing woody biomass indicates that neither whole-tree harvest nor whole-tree harvest combined with forest floor removal reduced forest productivity on silt-loam soils compared with conventional, stem-only harvest; however, moderate and heavy compaction did negatively impact aspen biomass and stem densities. In contrast, whole-tree …

Aging Horses By Their Teeth, Karl Hoopes, Patricia Evans, Nancy Jack
All Current Publications
This publication tells how to pinpoint a horses age, within a fairly narrow range, by examining its teeth. Being able to pinpoint age can be of use to owners of unregistered horses or horses whose age is unknown for any reason. Many health and nutrition management decisions are directly related to age and dental wear, making it even more important for all horse owners to have a general understanding of how a horse’s mouth changes with age. From a historical perspective, up until recently when organized associations started keeping birth dates on registered horses, most horse professionals took great pride …
