Online calculator helps homeowners preserve lawns while saving water

By Robert Burns
Texas AgriLife Extension Service

Drought or no drought, homeowners typically overwater their lawns, according to a Texas AgriLife Extension Service irrigation engineer.

It’s an expensive practice anytime, but during an extended drought, it’s particularly wasteful “and may lead to further water-use restrictions by communities if done by everyone, which is often the case,” said Dr. Guy Fipps, AgriLife Extension irrigation engineer.

Moreover, it’s unnecessary as there is an online calculator that will allow Texas homeowners to apply within a tenth of an inch of exactly the amount their turf grass needs, said Fipps, who is also the director of the Irrigation Technology Center at the Texas A&M University College Station campus.

“I guess a lot of people don’t know this sort of information and tools exist,” he said.

There is also a lot of misinformation circulating about, Fipps said.

“Look at garden sections in newspapers and elsewhere, you’ll typically see recommendations like water 1 inch to 2 inches a week, or that you should water infrequently and deeply — vague concepts like that,” he said.

There are lots of reasons such an approach isn’t appropriate, Fipps said. One reason is climatic variation.

“For example, this year we are having a very hot and dry summer, and water requirements are 30 percent to 50 percent higher than they would be in a more normal year,” he said.

In reality, the amount of irrigation a given variety of turf grass needs at any time depends upon many factors, such as temperature, humidity levels, wind, solar radiation and, of course, recent rainfall, if any, he said.

“The way you determine how much water grass actually needs is a fairly complex process, but fortunately, we have this website that does all that for you,” he said. “All you need to do is put in a little info about your location, the type of grass you’re growing, and what your goal is.”

Personal goals vary, he said. Some people don’t worry about the expense of watering and want a lawn as green as a golf course even during the drought. Others may want to strike a balance with the amount of water they apply, just wanting “pretty decent” turf quality. Others may want to conserve water and economize during drought restrictions and put on just enough water to keep the turf alive, he said.

“This choice greatly affects the amount of water you use and will double or triple the amount of irrigation water (in most parts of the state) from about 0.6 to 1.7 inches a week during August, and in West Texas from 0.9 to 2.2 inches a week,” Fipps said.

To use the online-calculator tool, go to the TexasET Network website at http://texaset.tamu.edu/.

The calculations are based on current weather data from nearly 30 automated scientific weather stations located throughout the state. Users must first pick one of these weather stations either from a drop-down menu or by simply clicking on the nearest one to them on the webpage’s Texas map.

They then must click on one of three buttons: “home watering,” “turf/landscape irrigation” or “crop irrigation.”

Beginners should choose “home watering,” Fipps noted.

“But once they are familiar with how it works, they should move to the turf/landscape calculator as it provides more options to customize recommendations for their grass and includes other plants as well,” he said.

From there on, it’s a matter of choosing the type of grass in the lawn, whether it’s in full sunlight or partial shade, and the amount of rainfall received in the last week.

The next decision is how long to irrigate. The parameter, “sprinkler precipitation rate” in inches per hour may give some homeowners some pause, but it’s easy to figure the rate, Fipps said.

“One simply puts out containers and run the irrigation system for a specified amount of time, usually 10 to 30 minutes,” he said. “Everything from tuna cans to cups are often used, but the results must be converted to inches of water applied over the area per unit of time.”

To make the process easier, Fipps designed the Aggie Catch Can. The catch can is cone-shaped and has graduated markings in both inches and millimeters to take the guesswork out of measuring, he said.

Aggie Catch Cans may be purchased as a kit on the AgriLife online bookstore at http://agrilifebookstore.org. For the Homeowner Kit, search for item number SP-424. Each kit comes with five cans and stands, as well as an instruction sheet, and costs $18.

“Unlike tuna cans, catch volumes may be read directly without the need for rulers or graduated cylinders,” Fipps said.


Attention Coastal Bend families: It’s time to get outside and connected with nature

Texas Forest Service

The statistics are staggering. Kids now spend an average of 45 hours each week — more time than their parents spend at work — in front of a computer or television screen.

It’s time to turn off the TV and power down the laptop. It’s time to get back outside and reconnected with nature.

It’s time for Nature Challenge 2011.

Like a family nature hike with a little Amazing Race thrown in, the contest is designed to help families across Texas get reconnected with each other — and the outdoors.

“We hope to instill environmental awareness in kids and families through hands-on activities rather than brochures and lectures,” said Dr. Melanie Kirk, assistant professor and urban forestry specialist with the Texas AgriLife Extension Service and co-founder of the program.

“We also hope to instill in them the importance of having healthy and renewable natural resources and being aware of the ecosystem around you. The things you do every day impact that ecosystem.”

Coordinated by Texas Forest Service and Texas AgriLife Extension, the competition is hosted regionally in six areas — Dallas-Fort Worth, Austin, Houston, San Antonio, Fort Davis and the Coastal Bend — throughout the year.

The contest calls for families to visit designated nature sites across the region in which they live, completing missions at each site. The families who complete the most missions are eligible for a grand prize.

Last year, more than 2,000 people — or 480 families — across the state participated in the regional contests.

Opening ceremonies for the Coastal Bend competition are scheduled for Saturday, Aug. 20, 2011, from 2 to 4 p.m. at the Hazel Bazemore Park Hawk Watch Tower between Robstown and Corpus Christi. Closing ceremonies will be held Saturday, Nov. 19, 2011, from 2 to 4 p.m. at the Nueces Delta Preserve in Odem.

“Nature Challenge is a competition that is driven around the experiences you have with your family and the memories you make that will last a lifetime,” said Lari Jo Johnston, environmental educator for the Coastal Bend Bays & Estuaries Program and regional coordinator for the Coastal Bend competition.

“We want to challenge you to get out and learn more about the area you live in, learn about the birds and flowers and what’s in your rivers and bays. The challenge itself is not about winning. The prize is that experience you’ve had with your family.”

Microalgae could be Texas’ next big cash crop

By Rod Santa
Texas AgriLife Extension Service

Just as corn and peanuts stunned the world decades ago with their then-newly discovered multi-beneficial uses and applications, Texas AgriLife Research scientists in Corpus Christi think microalgae holds even more promise.

“It’s a huge, untapped source of fuel, food, feed, pharmaceuticals and even pollution-busters,” said Dr. Carlos Fernandez, a crop physiologist at the Texas AgriLife Research and Extension Center at Corpus Christi who is studying the physiological responses of microalgae to the environment.

There are an estimated 200,000 to 800,000 species of microalgae, microscopic algae that thrive in freshwater and marine systems, Fernandez said.

Of all those species, only 35,000 species have been described, he said.

“We’re only starting to scratch the surface of discovering the natural secrets of microalgae and their many potential uses and benefits,” he said.

“But already it’s obvious that farmers will one day soon be growing microalgae on marginal land that won’t compete with fertile farmland. They won’t even compete for fresh water to grow.”

To understand how best to grow it, Fernandez constructed a microalgae physiology laboratory to study how it’s affected by temperature, salinity, nutrients, light levels and carbon dioxide.

“We have four bioreactors in which we grow microalgae to determine the basic physiological responses that affect its growth,” he said. “We will then integrate these responses into a simulator model, a tool we can use in the management of larger, outdoor systems.”

In this study, different strains of microalgae will be evaluated for their capacity to produce large amounts of lipids, or fats, that can then be converted to produce and refine diesel and other biofuels, Fernandez said.

“Along with that, after extracting the lipids from the biomass of microalgae, there is a residue that we are going to analyze for its quality for use as feed for animals, including fish, shrimp or cattle.”

Eventually, studies will evaluate the possibility of using the residue as a soil fertilizer.

“There are lots of other potential uses for the residue, but for now our focus is on feed and fertilizer,” he said.

The microalgae study includes other researchers, Fernandez said.

“We’ve just started this work and we’re working closely with the nearby Texas AgriLife Mariculture labs in Flour Bluff, under the direction of Dr. Tzachi Samocha, and the one in Port Aransas, under the direction of Dr. Addison Lawrence.”

Studying microalgae in the Corpus Christi area is a natural fit for many reasons, Fernandez said.

“We have immediate access to seawater to grow microalgae,” he said.

“Because we’re so close to the Gulf of Mexico, we’ve got lots of marginal land in the area where microalgae can be grown on a large scale. We have lower evaporation rates than in arid areas so water replacement is less.

“There are local power plants and oil refineries in the area that we can use as sources of carbon dioxide that helps microalgae grow while reducing CO2 pollutants. And we have a wealth of higher education institutions in the area with huge potentials to help in these studies, including Texas A&M at Corpus Christi, Texas A&M-Kingsville and Delmar College.”

AgriLife Research at Corpus Christi has partnered with the Barney M. Davis Power Plant to conduct this and other studies.

“It’s a natural gas-operated power plant that is an excellent source of carbon dioxide from its flue gasses that would reduce greenhouse gas emissions by passing them through microalgae systems,” he said.

There also is the potential to partner with the City of Corpus Christi, which has several municipal water treatment plants in the area that can be used as sources of nutrients to reduce the cost of applying them to microalgae systems, Fernandez said.

“Our center director, Dr. Juan Landivar, took a huge leadership role in moving these microalgae projects forward by seeking and obtaining federal and private funding, and by encouraging teamwork and multi-disciplinary personnel to work on this,” Fernandez said.


Beware of heat stress

The University of Texas at Dallas

When it comes to working and playing outdoors, it’s best to start slowly and acclimate to the heat, says Tom Monagan, associate athletic director at UT Dallas. “If not, you’re asking for problems. Most heat-related illnesses occur within the first few days of working out outside because the body isn’t used to the heat.”

Monagan offers these tips for acclimating and staying safe in the heat:

  • When working out, drink on a schedule, every 15-20 minutes or so, not when you’re thirsty. By then you’re already dehydrated.
  • Eat a well-balanced diet. Avoid caffeine and replace the sodium, potassium and carbohydrates you lose when working out and sweating.
  • Wear breathable clothing that allows sweat to evaporate off the body, and avoid wearing dark clothing — it attracts the heat.
  • Notice the color of your urine. It will help you know if you’re dehydrated. Urine should appear light yellow (the color of lemonade). Dark urine (the color of cider) indicates dehydration.
  • Trouble signs for overheating include headache, nausea, visual disturbances, vomiting and chills. Stop activity, drink fluids and head indoors when you experience any of these symptoms.

Gardening tips

"Deadheading Rhododendrons (Azaleas) can leave a sticky mess on your hands," writes Cathie Nicolaus. "To make the wash up easier, start by rubbing some olive oil on your hands and finger tips. Deadhead as usual, and then after your chore is done, wash with soap and water. The resin comes off easier and the olive oil leaves your hands smooth and moisturized."

San Angelo: There’s still hope for home grown veggies this year for those who plant a fall garden, according to Texas AgriLife Extension Service expert. To help gardeners succeed, the AgriLife Extension office in Tom Green County will conduct a fall vegetable gardening class at 6 p.m., August 30, at the Tom Green 4-H Center, 3168 N. U.S. Highway 67. “Most gardeners have struggled with their vegetables this summer,” said Allison Watkins, AgriLife Extension horticulturist in Tom Green County. “The heat and drought have made it very difficult to grow healthy, productive plants. Many people don’t realize that fall is a great time to garden. Milder temperatures and fewer pests allow vegetable plants to produce well, making them easier to care for than in the late spring and summer.” Watkins said the class will provide information on planning and preparing a fall garden, pest control, crop selection and timing, and gardening basics. There will also be a question and answer session at the end of the program. “Even some avid summer gardeners don’t realize that many of their favorite spring garden plants such as tomatoes and squash can be successfully grown in the fall,” Watkins said. “Then later in the season there are cool-season crops to consider such as spinach and broccoli. And best of all? It’s way more pleasant to work outside when it’s cooler.” Watkins said gardeners further north in the Panhandle might run into trouble with cold weather hindering warm season vegetable crops, but they can certainly plant cool season crops successfully. The deadline to register is Aug. 23. Individual registration is $25 which includes a meal, a tomato plant and a chance at door prizes. Participants can pay at the door, but all must RSVP to attend by contacting Watkins at 325-659-6522 or aewatkins@ag.tamu.edu.

In Greg's Garden:
A Pineywoods Perspective on Gardening, Nature and Family

An intimate and personal exploration of the life of one of Texas’s most beloved gardeners, In Greg’s Garden: A Pineywoods Perspective on Gardening, Nature and Family gathers in a single volume the first nine years of Greg Grant’s columns from Texas Gardener magazine.

Revised and updated from their original publication, these 54 essays reveal the heart and soul of a seventh generation native Texan who has devoted his entire life to gardening, nature and family. With degrees in floriculture and horticulture from Texas A&M University and extensive hands-on experience as a horticulturist with the Texas Agricultural Extension Service, Stephen F. Austin State University, Mercer Arboretum and San Antonio Botanical Gardens, Grant has successfully introduced dozens of plants to the Texas nursery industry, all while maintaining long-held family property and renovating the homes of his ancestors in Arcadia, Texas.

In Greg’s Garden: A Pineywoods Perspective on Gardening, Nature and Family is a must-read for every Texas gardener.
