Size and Scope of Utah Agriculture 2019

Utah is part of the Mountain West region of states and is bordered by Idaho to the north, Wyoming to the northeast, Colorado to the east, Arizona to the south, and Nevada to the west. It also shares its southeast corner with New Mexico. As of July 1, 2019, the U.S. Census Bureau (2019) estimated the population of Utah was 3,205,958. This fact sheet explores the land use and ownership, climate and growing season, crop and livestock production, irrigation, and information regarding farm income and operators in the state of Utah

Erosion Function Apparatus

The Erosion Function Apparatus (EFA) test uses site-specific soil samples acquired via thin-walled tubes to generate the erosion rate and shear stress which is plotted to create an erosion plot. The information produced by the test can help an engineer accurately determine the depth of scour as a function of time for bridge design, and thereby determine the depth a foundation system should be constructed. During EFA testing, a data acquisition system records the velocity and amount of soil eroded. This data is used to calculate the Reynolds Number, friction factor, erosion rate, and shear stress. Once the data has been reduced to erosion rate and shear stress, it is plotted to form an EFA plot. The EFA test contains significant uncertainties in selecting the roughness values and timing of the test. Selecting incorrect roughness values can produce a misleading EFA plot by incorrectly calculating the shear stresses, which will not be representative of the erodibility of the soil. Incorrectly timing the test will also lead to an inaccurate representation of the erodibility of the soil by improperly calculating the erosion rate

The Development of Polyamines throughout Brassica rapa over its Lifecycle

Polyamines are naturally produced chemicals in plants involved in growth, development and stress response. The primary objective of my study is to create a profile of changes in the entire life of the plant, in every organ at all stages of development from seed germination to seed formation. We have analyzed polyamines putrescine, spermidine and spermine in all parts of Brassica rapa, a small, rapid growing plant. Parallel to the polyamines, we will also study changes in the activities of the polyamine biosynthetic enzymes and the expression of their genes in different organs at different times. In the next stage of the study, the expression of selected genes will be inhibited by RNAi constructs, allowing further analysis of their role in growth and stress response. Because polyamines play are important in development and lifecycle of plants, altering their presence may be useful in altering plant growth patterns, such as in seasonal crops
