Lawn Fertilizers For Cool Season Turf, Taun Beddes, Kelly Kopp

All Current Publications

Lawns provide a durable and functional surface for many outdoor activities while adding beauty to the landscape. For these reasons, a healthy, green lawn is the goal of many homeowners and landscape managers. Keeping a lawn healthy and green may require many management practices such as mowing, irrigation and aerification. Often, these practices will include fertilizing with supplemental nutrients at various times during the growing season. This promotes optimum turf color, improves re-growth, and increases tolerance to wear, drought, insects and disease. The broad number of fertilizer options available from retailers can make choosing a fertilizer difficult. However, choosing an …

Western Tentiform Leafminer Phyllonorycter Elmaella, Diane G. Alston, Michael E. Reding

All Current Publications

Western tentiform leafminer populations can vary tremendously between years or even between generations within a single year. A large population in Utah's commercial fruit districts hasn't been observed since the early 2000s. Increasing resistance to organophosphate insecticides and variable effectiveness of at least six parasitic wasp species that attack the leafminer can influence the population size.

Propagating Bigtooth Maple, Melody R. Richards, Larry Rupp May 2011

Propagating Bigtooth Maple, Melody R. Richards, Larry Rupp

CWEL Extension Fact Sheets

Native plants are playing an increasing role in sustainable landscapes that use fewer resources such as water and fertilizer. Unfortunately, many native plants are not available in the nursery trade, or if they are available they may only be found as seedling plants grown for the reclamation industry. Such plants are high quality and have a valuable role in the reclamation of disturbed sites such as fire-damaged areas. But, these plants by design are genetically diverse and have not been selected for typical horticultural traits such as flowering or fall color. In addition, plants produced for reclamation are usually not …

Drought Tolerance A Database Of Irrigation Requirements For Woody Plants Of Northern Utah, Samuel Cook, Larry Rupp

CWEL Extension Fact Sheets

It differs from other lists of plant water requirements in that it is a review of the published literature including citations of previous research and observations. The need for a documented review is apparent as one studies the database. It can be seen that much of the water use assessments used by the industry …

Solutions To Soil Problems: Ii. High Ph (Alkaline Soil), Loralie Cox, Rich Koenig Dec 2010

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.
