Suggested Vegetable Planting Dates: Grand And San Juan Counties, Reagan Wytsalucy, Cory Farnsworth, Dan Drost Mar 2024

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) …

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 …


Agricultural Irrigated Land And Irrigation Water Use In Utah, Burdette Barker, Matt Yost, Cody Zesiger Jul 2023

Agricultural Irrigated Land And Irrigation Water Use In Utah, Burdette Barker, Matt Yost, Cody Zesiger

All Current Publications

Utah is considered the second driest state in the United States. As a result, much of the agriculture and horticulture in Utah depends upon irrigation. Irrigation is an important feature of agriculture in Utah. The distribution of irrigated and water use varies across the state, based on water availability, topography, and soils. In recent years, sprinkler irrigation has overtaken surface methods as the dominant irrigation method, based on irrigated area, in Utah. About 75% to 80% of water withdrawals in Utah are for irrigation, with about 68% of that water being consumptive use. Alfalfa, other hay crops, and pasture are …


Data From: Yellow Air Day Advisory Study, Arthur J. Caplan Aug 2021

Data From: Yellow Air Day Advisory Study, Arthur J. Caplan

Browse all Datasets

Using a dataset consisting of daily vehicle trips, PM2.5 concentrations, along with a host of climactic control variables, we test the hypothesis that “yellow air day” advisories provided by the Utah Division of Air Quality resulted in subsequent reductions in vehicle trips taken during northern Utah’s winter-inversion seasons in the early 2000s. Winter inversions occur in northern Utah when climactic conditions are such that PM2.5 concentrations (derived mainly from vehicle emissions) become trapped in the lower atmosphere, leading to unhealthy air quality (concentrations of at least 35 µg/m3) over a span of what are called “red air days”. When concentrations …

The Three Creeks Allotment Consolidation: Changing Western Federal Grazing Paradigms, Taylor Payne Jan 2018

The Three Creeks Allotment Consolidation: Changing Western Federal Grazing Paradigms, Taylor Payne

Human–Wildlife Interactions

The federal government owns approximately 47% of all land in the western United States. In the state of Utah, about 64% of the land base is managed by the federal Bureau of Land Management (BLM) and the U.S. Forest Service (USFS). The government has historically issued permits to owners of private lands to allow the owners to graze their livestock on public lands. The permits (allotments) are generally of 10-year duration and allow for an annual season of use. In some cases, continued and repeated historical annual grazing practices may not be ideal for permit holders and their communities nor …
