Solutions To Soil Problems: Ii. High Ph (Alkaline Soil), Loralie Cox, Rich Koenig
All Current Publications
PH is a measure of the acidity or alkalinity of a material. The pH scale ranges from 0 to 14, with 7 being neutral. A pH value below 7 indicates the soil is acidic, while values above 7 are alkaline. Each unit change in the pH scale is a 10-fold difference in acidity or alkalinity. For example, soil with a pH of 8 is ten times more alkaline than soil with a pH of 7.

Solutions To Soil Problems: I. High Salinity (Soluble Salts), Vernon Parent, Rich Koenig
Solutions To Soil Problems: I. High Salinity (Soluble Salts), Vernon Parent, Rich Koenig
All Current Publications
Salinity is a measure of the total amount of soluble salts in soil. As soluble salt levels increase, it becomes more difficult for plants to extract water from soil. Some plants are more resistant than other’s, but as the salt levels exceed their ability to extract water, they become water stressed.

All Current Publications
Soil structure refers to the combination of primary soil particles – sand, silt and clay – into larger units called aggregates or clods. Aggregates are commonly seen when a soil is tilled or disturbed.
Solutions To Soil Problems: V. Low Organic Matter, Kevin Heaton, Rich Koenig
Solutions To Soil Problems: V. Low Organic Matter, Kevin Heaton, Rich Koenig
All Current Publications
Utah soils are inherently low in organic matter due to the desert climate and historically low plant growth rates. In Utah, soil organic matter levels are typically 0.25 to 1%, while regions with high rainfall such as the Midwest and Eastern United States have soils with as much as 7 to 10% organic matter.
Africanized Honey Bee, Erin W. Hodgson, Cory A. Stanley, Alan H. Roe, Danielle Downey
Africanized Honey Bee, Erin W. Hodgson, Cory A. Stanley, Alan H. Roe, Danielle Downey
All Current Publications
African honey bees (Apis mellifera scutellata) are native to sub-Saharan Africa and were introduced in the Americas to improve honey production in the tropics. These African honey bees were accidentally released and began to interbreed with European honey bees (Apis mellifera ligustica), the most common subspecies used for pollination and honey production in the United States (Fig. 1). As a result, the hybrid offspring are called “Africanized” because of their shared characteristics. Africanized honey bees are about the same size, shape and color as European honey bees (Fig. 2), and a genetic analysis must be used to distinguish one from …
Cat-Facing Insects, Diane Alston, Michael Reding, Marion Murray
Cat-Facing Insects, Diane Alston, Michael Reding, Marion Murray
All Current Publications
There are a number of insects with the piercing-sucking feeding habit that can cause deformity and catfacing type injury to pome and stone fruits, including lygus bug, stink bug, and boxelder bug. Cat-facing injury is caused by puncture feeding in flower buds and fruit. The result is unsightly dimpling, deformity, and scarring of fruit. The name “cat facing” comes from the distorted fruit shape that resembles the puckered cheeks of a cat. In addition to the insects discussed in this section, some aphids and the campylomma bug can inflict similar injury.

All Current Publications
Raising meat-type chickens at home can be a rewarding and productive experience. Not only does it put meat in the freezer, it can also be a great 4-H project for young poultry enthusiasts. Many counties provide opportunities at fairs and other venues to show broilers in competition.
Chinch Bugs, Kelly Kopp, Ryan S. Davis, Ricardo A. Ramirez
Chinch Bugs, Kelly Kopp, Ryan S. Davis, Ricardo A. Ramirez
All Current Publications
Chinch bugs are “true bugs”. In Utah, the common chinch bug [Blissus leucopterus leucopterus (Say)], and western chinch bug (Blissus occiduus) may feed on turfgrass, especially under conditions of severe heat and drought. Coupled with under-irrigation, direct sunlight, and thick thatch, chinch bug numbers can soar from mid-summer to early fall.
Japanese Beetle, Erin Hodgson, Diane Alston, Cory A. Stanley
Japanese Beetle, Erin Hodgson, Diane Alston, Cory A. Stanley
All Current Publications
The Japanese beetle, Popillia japonica Newman, can be a highly destructive pest to ornamentals, trees, shrubs, turfgrass, and vegetables. First discovered in the eastern United States in 1916, the Japanese beetle has threatened agriculture and horticulture by slowly moving south and west. In 2006, a small population of adult Japanese beetles was detected in Orem, Utah.

Turfgrass Cultural Practices And Insect Pest Management, Diane Alston, Kelly Kopp
All Current Publications
There are a number of insects that can cause aesthetic and economic loss to turfgrass in Utah – in home lawns as well as in athletic fields and on recreational lands. Good turfgrass cultural practices are the primary way to prevent insect infestation and turfgrass damage.

Boxelder Bug, Erin W. Hodgson, Alan H. Roe
Boxelder Bug, Erin W. Hodgson, Alan H. Roe
All Current Publications
Boxelder bugs are a common nuisance insect to many homeowners. Although boxelder bugs are active throughout the summer, many people don’t notice them until they start “sunning” themselves on structures, particularly the southern-facing walls. As temperatures start to decrease in the late summer and fall, large numbers of adults will move from plants and congregate on heated buildings.
Control Of Iron Chlorosis, Rich Koenig, Michael R. Kuhns
Control Of Iron Chlorosis, Rich Koenig, Michael R. Kuhns
All Current Publications
Iron deficiency (iron chlorosis) affects many desirable landscape and crop plants grown in Utah. The primary symptom of iron deficiency is interveinal chlorosis, the development of a bright yellow leaf with a network of dark green veins. In severe cases, the entire leaf turns yellow or white and the outer edges may scorch and turn brown as the plant cells die.

Biosecurity Principles: Protecting Your Investment, David D. Frame
All Current Publications
Although the magnitude of economic value is usually much less in small standard-bred poultry operations compared to multimillion-dollar commercial chicken or turkey companies, there are still many reasons to protect your investment. Value is not always measured in simple dollar terms.
Solutions To Soil Problems: Iii. Drainage, Michael Johnson, Rich Koenig
Solutions To Soil Problems: Iii. Drainage, Michael Johnson, Rich Koenig
All Current Publications
Drainage is a common problem throughout Utah. Complex patterns of soil development, transport and deposition have resulted in excessively drained soils that are coarse-textured (sandy or rocky), and poorly drained soils that are fine-textured (silt and clay-dominated). Excessively drained are more common in higher elevation and bench areas.

All Current Publications
With an increase in backyard poultry raising, and even keeping poultry as pets, it is necessary to keep in mind proper health concerns in handling baby poultry. Chickens, ducks, geese, turkeys, peafowl, and game birds can harbor and transmit certain agents that might infect people. This fact sheet will review practices that will help minimize the chance for disease transmission between you and your poultry.
