Maintaining And Improving Irrigation Application Uniformity In Sprinkler And Drip Systems, Burdette Barker, Sheridan Stewart, Mark Nelson Apr 2024

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 …

Managing Saline And Sodic Soils And Irrigation Water, Burdette Barker, Grant Cardon, Matt Yost, Melanie Stock, Earl Creech, Jody Gale

All Current Publications

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 …

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 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 …

Managing Soil Ph For Crop Production In Calcareous-Alkaline Soil, Cody Zesiger, Jody Gale, Matt Yost, Grant Cardon Dec 2023

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 …

Guide To Pivot Track Management, Matt Yost, Behnaz Molaei, R. Troy Peters, Clara Anderson, Burdette Barker, Jonathan Holt, Dustin Larsen

All Current Publications

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.

Manure And Wastewater Sampling Guide, Rhonda Miller, Cody Zesiger, Kalen Taylor, Matt Yost Nov 2023

Manure And Wastewater Sampling Guide, Rhonda Miller, Cody Zesiger, Kalen Taylor, Matt Yost

All Current Publications

Manure and wastewater are resources that can reduce your fertilizer needs and help improve soil and your bottom line. It is important that manure and wastewater be sampled and tested so one can apply the manure and nutrients appropriately. Sampling and analysis should occur as close to land application as possible as nutrient concentration in manure and wastewater can change over time due to runoff, leaching, and changes in moisture percentage. Nitrogen can also be lost due to volatilization. There are two primary approaches for when to sample: (1) just before land application, and (2) at the time of land …

Sudden Oak Death And Ramorum Blight, Marion Murray, Ann Mull Sep 2023

Sudden Oak Death And Ramorum Blight, Marion Murray, Ann Mull

All Current Publications

Sudden oak death (SOD) and ramorum blight are caused by Phytophthora ramorum, a non-native water mold (oomycete) that originates from parts of Asia. Sudden oak death was given its name due to the appearance that entire trees were dying in just 2 to 4 weeks. In reality, the disease progresses over an extended period, estimated at more than 2 years after initial infection. Ramorum blight is nonlethal, typically causing foliar browning and wilting. This fact sheet discusses impact, damage and symptoms, plant hosts, disease cycle, and management.
