WaterMyYard can assist with watering decisions

For the past 16 years, the Irrigation Association has designated July as “Smart Irrigation Month.” Typically, July is the summer month when most water is applied for landscape irrigation. However, much of this is wasted due to inefficient watering practices.

“Smart Irrigation Month” is an effort to educate business owners, homeowners, and others about the importance of efficient landscape irrigation practices.

DO your part to water smart!

With that in mind, High Plains Underground Water Conservation District (HPWD) began its local sponsorship of the WaterMyYard program last month. Cities, public utilities, and water districts partner with Texas A&M AgriLife Extension Service on the project. It is free of charge to users within the sponsor’s respective service areas.

“Landscape irrigation accounts for 50 to 80 percent of the water used in a home during summer months. HPWD is testing the WaterMyYard program in an effort to take some of the guesswork out of landscape irrigation scheduling,” said Carmon McCain, Information/Education Supervisor. If successful, WaterMyYard may be implemented as a water conservation tool in other portions of the 16-county HPWD service area.

“The WaterMyYard program uses scientific data obtained from weather stations to determine how much water plants need, based upon local climate and other factors,” said Charles Swanson, AgriLife Extension landscape specialist at College Station.

The HPWD Lubbock County weather station is located in the City of Wolfforth. The station records evapotranspiration rates, total rainfall, average maximum and minimum temperature, total solar radiation, and average daily wind speed at 4 a.m. and 4 p.m.

Swanson says it is important to note that WaterMyYard uses the standard evapotranspiration (ET) crop coefficient for warm season grasses, such as Bermudagrass, Buffalograss, St. Augustine, and Zoysia. It does not incorporate cool season grasses, such as Bluegrass, Fescue, or ryegrass at this time.

WaterMyYard includes sprinklers and drip irrigation products from all major manufacturers, according to Dr. Guy Fipps, AgriLife Extension irrigation engineer at College Station. He says the program is not just for those who have permanent in-ground irrigation systems. Homeowners who use hose-end sprinklers can also get weekly runtime recommendations.

Texas A&M AgriLife Extension released its new WaterMyYard mobile app on June 29.

“The app has several enhancements compared to the website-based program we’ve offered the past few years,” said Fipps. “It incorporates new, advanced features and tools to maximize landscape water conservation. Advanced features include options for push notifications in addition to text and email messages. Users can also enter on-site measured rainfall and adjust sprinkler runtimes for landscape conditions,” he said. The app is available as a free download from Apple Store and Google Play.

Persons can visit www.hpwd.org/watermyyard to sign up for the program.

WaterMyYard started in response to the severe 2011 drought across Texas. North Texas Municipal Water District was the initial program sponsor. Since then, Fort Bend Subsidence District, Harris Galveston Subsidence District, HPWD, City of Irving, Lower Colorado River Authority (LCRA), Memorial Villages Water Authority, Park Cities Municipal Utility District, City of San Angelo, Upper Trinity Regional Water District, and West Harris Regional Water Authority have signed on as sponsors.

Currently, there are more than 25,000 subscribers to the WaterMyYard program in Texas.

Water efficiency of Zoysia grass in Texas Panhandle

BUSHLAND – The front lawn of a home built during the Dust Bowl on a location known for soil and water conservation research is the perfect place for a turfgrass project aimed at finding a water-smart alternative to Bermuda and fescue grasses for the High Plains, according to project participants.

The new turf grass demonstration has been installed in front of the 1938-vintage “white house” at Bushland, the original headquarters of the Conservation and Production Research Laboratory which is now jointly operated by the U.S. Department of Agriculture-Agricultural Research Service and Texas A&M AgriLife Research.

The project, titled Zoysia Turfgrasses for Residential and Commercial Landscapes in the Texas Panhandle, will be conducted by Dr. Brent Auvermann, AgriLife Research center director, Amarillo; Dr. Ambika Chandra, AgriLife Research turfgrass breeder, Dallas; and Dr. Gary Marek, USDA-ARS research agricultural engineer, Bushland.

This demonstration will have a state-of-the-art irrigation system and two varieties, “Chisholm” and “Innovation,” recently released by Chandra and Dr. Jack Fry, Kansas State University turfgrass science professor, Manhattan, Kansas.

Zoysia, compared to other warm-season turfgrasses, generally produces higher quality turf requiring fewer inputs like mowing, nutrients and chemicals due to its natural tolerance to disease, insects, shade and salinity stress, Chandra said.

She has been breeding freeze-tolerant zoysia grass varieties as part of an ongoing project since 2003 with Kansas State.

“While zoysia’s low input requirements, strong shade tolerance and salinity tolerance make it an attractive option for use across the U.S., most species are still found in the southern U.S. due to low tolerance for freezing temperatures,” Chandra said.

The Dallas Center’s turf breeding program produced 640 zoysia hybrids in 2004 and sent them to Kansas to be evaluated for cold tolerance. The breeding lines that survived the cold were evaluated for aesthetic quality and a range of other characteristics, Chandra said.

Chisholm, licensed to Carolina Fresh Farm, is a medium-texture zoysia that is cold hardy into the northern region of the U.S. transition zone. It features rapid establishment and recovery rates as well as superior turf quality compared to Meyer zoysia. Chisholm underwent testing in the National Turfgrass Evaluation Program’s 2002 Zoysiagrass Test as DALZ 0102.

Innovation, originally KSUZ 0802 and licensed to Sod Solutions, features finer leaf texture and superior density to Meyer, she said. It is a good option for landscapers and end users in the transition zone and beyond who are looking for a cold hardy hybrid for golf courses, yards, parks and commercial establishments.

“I expect both of these varieties to not only survive the Texas Panhandle climate, but to produce good turfgrass quality with limited resource input,” Chandra said.

Auvermann said half the sod in the Bushland side-by-side variety comparisons was laid on existing soil; the other side on existing soil amended with composted cattle manure to test what role fertility and organic matter have in its survivability.

“We think the zoysia grass will provide an alternative for landscape contractors for both residential and commercial markets,” he said. “Zoysia grasses act a little bit like Bermuda grass in that they creep and repair themselves. They also use less water than the fescues typically used for the landscaping projects in the Texas Panhandle.”

Marek said developing irrigation scheduling strategies for seasonal crops is one of the primary research goals of the USDA-ARS program at Bushland. Prudent irrigation scheduling provides enough water to achieve desired yield goals but prevents overwatering that results in water percolating below the root zone.

“Those same concepts can be applied to turf irrigation,” he said.

Traditionally, Marek said, there are three grass varieties available to homeowners for turfgrass – fescue, Bermuda and buffalo grass, with fescue using the most water. Fescue greens up earlier and stays green longer than other varieties, so aesthetically, it is generally more pleasing.

“However, fescue can use up to a half-inch of water per day on hot, windy days typical of the Panhandle summers,” he said.

“One of the benefits we hope to evaluate in this trial is to see if these zoysia varieties can compare to fescue grass in aesthetics while using less water,” Marek said.

In addition to the water use, the other aspect of the project is to determine how well the zoysia grass overwinters in the colder climate of the Panhandle, Marek said.

“If these two varieties prove adapted to our climate, as we expect, they ought to use significantly less water than our typical tall fescues, heal themselves, withstand the winters and maintain a luxurious, fine-bladed turf,” Auvermann said.

This project is funded in part by the federal Ogallala Aquifer Project.
