Ag irrigation strategies discussed at Jan. 24 TAWC Water College

Variable rate irrigation technology, soil management, upcoming weather patterns, and an evaluation of various irrigation systems were among the topics discussed at the Jan. 24 Texas Alliance for Water Conservation (TAWC) Water College.

Approximately 244 persons attended the day-long event and trade show at the Lubbock Memorial Civic Center.

TAWC producer Lloyd Arthur told the group that he is "a big believer" in variable rate irrigation technology which enables him to speed up or slow down his center pivot system as needed to reduce water losses.

"I can speed up the pivot to get across terraces, turnrows, and pivot access roads to reduce runoff and then slow it down to apply water to the more profitable part of the field. This helps optimize every acre," he said.

Use of soil moisture sensors aided Arthur in adjusting the run times of his center pivot and drip irrigation systems.

"Information from the sensors sent to my phone showed me that some of the water being applied was not making its way to the plant roots. Because of this, I adjusted my pivot and drip system run times accordingly."

TAWC producer  R.N. Hopper discussed various paradigms that he and his father, Ronnie, have  encountered in their farming operation. They included furrow irrigation, center pivots, Roundup Ready seed, no-till operations, and biological soil health.

"We thought each was the best solution but outlooks change over time as a result of weather, new crop varieties, new technologies, economics, and other variables. We don't go back and judge these past paradigms because they were the best management practices that we could accomplish at the time," said Hopper.

Roian Atwood, Director of Sustainability for Wrangler, discussed the denim company's recent partnership with the TAWC program.

TAWC will serve as an advisor to Wrangler's U.S. sustainable cotton program. Wranger, in turn, will help promote awareness of best farm management practices  resulting from TAWC's on-farm research.

Wyman Meinzer, official photographer of the State of Texas, was the keynote lunch speaker. 
He shared his three-year experience photographing the San Antonio Viejo Ranch in Jim Hogg County for the upcoming book, Horses to Ride, Cattle to Cut. It details the 100-year history of the ranch and the ranching heritage of the Tom T. East family.

TAWC producer Glenn Schur provided results of a center pivot technology demonstration that compared crop yields under Low Drift Nozzles, LEPA, LESA, and Precision Mobile Drip Irrigation.

Other presentations included an update from Texas Water Development Board member Kathleen Jackson, an overview of Texas water law, discussion of profit potential using split pivot irrigation technologies in cotton production, a look at upcoming weather patterns, a review of producer tools available through the West Texas Mesonet, and ways to improve corn water use through hybrid selection.

Healthy soils conserve water

From the Fall 2017 HPWD Conservation Connect magazine


During a recent crop residue field day in Hale County, USDA-NRCS Zone Agronomist Brandt Underwood placed two soil samples onto pieces of mesh and then submerged them in individual cylinders filled with water.

 As the Slake Test progressed, people watched as most of the conventionally tilled soil fragments quickly dissipated within a five-minute period.  The minimum tillage soil fragments, containing higher organic matter, remained in the mesh for an extended time.

 “As this demonstrates, the minimum tillage soil has greater structure (tilth) which provides greater stability. This improves soil aeration and water retention while reducing erosion and nutrient leaching,” said Underwood.

 Many High Plains agricultural producers are working to improve their soil health to increase crop yields and better utilize their groundwater resources.

 Conservation tillage and/or no-till operations are one way to accomplish this.

 “This is a way to put the soil back in balance and return it to a natural state. Most of the soil activity is currently bacterial, which burns up organic material and nutrients. Bringing the fungal level back to a natural state will be beneficial in the long run.” said Jeff Miller with ForeFront Agronomy.

 He said soil contains 45 percent minerals, 25 percent water, 25 percent air, and five percent organic matter. Of the organic matter, 80 percent is humus, 10 percent are roots, and 10 percent are organisms, such as bacteria and fungi.

 “Water must displace air to enter the soil. The higher the bulk density, the greater the soil compaction.  Soils with high compaction are likely to have poor water infiltration rates and slower root growth. No-till can increase water infiltration rates in the soil by as much as 10 percent. There is also a 10 percent increase in rooting depth,” said Miller.

 He noted that test plots with lower crop residue required an additional 1.5 to 2.5 inches of irrigation water to achieve the same crop yield as compared to plots with residue on the surface. At the end of the growing season, plots with more residue contained an additional 1.5 inches of water in the top four feet of the soil profile as compared to those plots with no residue cover.  Plots with residue on the soil surface would save three to four inches of irrigation water as compared to bare soil.

 No-till operations have been fairly common in Kansas for many years. However, Miller said the practice is in its infancy here on the Panhandle-South Plains.

 “It got a bad rap because some folks were doing it incorrectly.  You can’t have a monoculture crop, such as cotton only. There must be multiple crops grown during multiple years for it to work properly.  With that in mind, some producers are taking a second look at no-till.  They are adding cover crops to their farming operations. Some are considering nutrient recapture to increase soil organic matter and reduce compaction,” he said.

 Miller believes no-till farming can be beneficial to the region.

 “We’ve seen advances in irrigation technology that allows water to be applied more efficiently.  Now, we’re seeing new ways to improve irrigation management and scheduling. This allows producers to make better decisions, which we hope will help slow groundwater decline in our area,” he said.

 Kelly Kettner, who operates a 4,000 acre farm in Lamb and Parmer Counties, has used no-till farming practices since 2004. His main crops include cotton, corn, sorghum, wheat, and barley.

 Initially, he stopped plowing in an attempt to halt soil erosion.  “I was frustrated by having to go out and run a sand fighter.”

 However, attendance at the 2009 No Till On The Plains conference in Kansas gave Kettner an understanding that no-till farming is much more than simply choosing not to plow fields.

 “It showed me the importance of noticing your native ecosystem and trying to mimic it through farming practices using summer and winter cover crops,” he said.  It was then that he starting using a true no-till system with cover crops and strategic crop rotations.

 The Muleshoe producer has seen many benefits from converting to no-till farming.

 “My soils are definitely healthier. I have many earthworms now—and after rain events, I see mushrooms and white fungi growing on the old crop residue. Fungus is the ‘glue’ that holds organic matter in place. This allows water and nutrients to be readily available for growing crops,” Kettner said.  He added that his soil has a soft, sponge-like texture when he plants his summer cash crop following the winter killed cover crop.

 He has also observed an increase in crop water use efficiency.

 “Water use efficiency has greatly increased since adopting no-till practices. Very seldom do I irrigate cotton before bloom and I can usually delay watering corn until the v6 stage.  The only exception is if we have a dry spring and the cover crop has depleted moisture stored in the soil profile,” he said.

 Input costs, such as fuel for plowing, have also reduced.  “I’m no longer making multiple trips across the field to plow.  The cover crops provide plant competition to control weeds. Residual weed control is important because you don’t have any mechanical options other than a hoe.”

 Kettner said patience is a virtue when converting from conventional tillage to no-till. During his 13 year experience, there were many times when he was ready to just give up and go back to conventional farming methods. Yet, through it all, he has remained focused on improving the health of his soil.

 “There is no textbook about how to farm with a no-till system. Be patient and figure out how to make no-till fit your farm management style and mix of crops. It requires more management and planning than conventional farming.  The first few years of no-till can be challenging because your soils are making the transition from a bacterial dominated system to a fungal dominated system. You may not see the full benefits at first,” he said.

 The primary disadvantage to high residue no-till farming is having cool soils at planting time.  This is not an issue with corn, but it could result in a delayed cotton crop. Miller said test plot observations showed soil temperatures at planting were 8 percent cooler with no-till as compared to conventional tillage.  However, they were about the same once crop canopy closure was achieved.

 Kettner is among a group of farmers that attend the No-Till On The Plains conference in Kansas each year.  “Call us a support group, if you will, but we have developed a relationship that allows us to bounce ideas off each other and offer suggestions to one another. Although our operations are very different, we each have a common goal in mind regarding soil health and structure,” he said.

 “It takes a while to get over the idea that the cover crop is going to use some of our precious water. You have to be able to see that the cover crop is actually going to help you capture more water for your cash crop,” he said.

Web tool helps with voluntary water use reporting

Persons interested in participating in the High Plains Water District (HPWD) groundwater conservation reserve program are reminded that they should report their 2017 water use before March 1, 2018.

The reporting is voluntary and can be accomplished using the web tool located at 

The web tool provides options for persons to select either a simple or detailed reporting method, depending upon their choice for participating in the groundwater conservation reserve program.

Those who do not report their groundwater use are presumed to take the “One Irrigated Crop” option, which indicates that they planted and harvested one irrigated crop during the 2017 growing season. 

The Rule 5 infographic explaining the eight reporting options available to producers is located at

Please contact Jed Leibbrandt at (806) 762-0181 or with any questions about reporting 2017 groundwater use.

RCPP funds available for irrigation monitoring equipment

Are you interested in adding telemetry-based monitoring equipment to the irrigation system on your farm?  If so, stop by your local USDA-NRCS service center to ask about cost-share funding available through the Regional Conservation Partnership Program (RCPP).

This equipment, typically used with a center pivot or subsurface drip irrigation system, allows monitoring data to be transmitted by telemetry to smart phones, tablets, or other handheld devices. These data help determine if irrigation systems are operating at peak efficiency - which results in water and energy savings for producers.

The RCPP program is an option for producers that were unable to receive funding from HPWD's Assistance in Irrigation Management (AIM) program. The $225,000 in grant funding provided by the Texas Water Development Board was claimed by producers in less than two weeks after the program was announced in August.

This equipment is being cost-shared through RCPP, which is administered by the USDA-NRCS, and requires "a flow meter to be installed on the irrigation system where the irrigation system monitoring system is installed as a companion device."  If a contract is awarded, payment for these practices cannot be made until the first year's monitoring data are provided to the NRCS.

About $900,000 in funding was allocated for the five year program (2016-2020). As of Dec. 8, USDA-NRCS officials said the agency has obligated 39 contracts totaling $227,208 on 24,772 acres. This leaves $672,792 in available funds for the remainder of the program.

Participation in RCPP is entirely voluntary. Interested producers can sign up for the program at their local USDA-NRCS service center.

High Plains Underground Water Conservation District (HPWD) in Lubbock serves as the lead RCPP partner. Supporting partners include Hemphill County UWCD in Canadian, Llano Estacado UWCD at Seminole, Mesa UWCD at Lamesa, North Plains GCD at Dumas, Sandy Land UWCD at Plains, and South Plains UWCD at Brownfield.

These groundwater conservation districts do not receive any funding for the program, but provide in-kind services to assist with water conservation efforts.

Additional information about RCPP is available at USDA is an equal opportunity provider, employer, and lender.

Drought conditions prevalent at end of 2017

By Katherine Drury, Education and Outreach Coordinator

Despite above-average precipitation, all of the High Plains Water District (HPWD) service area was experiencing drought conditions at the end of 2017.
Most of the District is currently under severe drought status, according to the U.S. Drought Monitor. Deaf Smith and Parmer Counties, along with portions of Bailey, Castro, and Cochran Counties, are classified under moderate drought conditions.
Though most of the HPWD service area received above-average rainfall in 2017, the majority of the precipitation was received throughout the first nine months of the year.
Castro County had the greatest deviation from the annual precipitation average.  It received 26.47 inches of rain last year, which is 13 inches above normal. Lynn County was the only county that experienced a precipitation deficit, nearly four inches below average.
So, what is in store for 2018?
The dry La Niña pattern is expected to stick around until April, according to the National Oceanic and Atmospheric Administration (NOAA).
KCBD-TV Meteorologist Steve Devine said precipitation will likely be below average through the summer. Fall and winter 2018 precipitation may trend toward average. Temperatures for 2018 are expected to be above average as a whole.
With this in mind, HPWD encourages everyone to be aware of their water use during these dry times!

  • Be aware of your local landscape irrigation ordinances, and abide by them.
  • Make sure your lawn irrigation system is off during the winter.
  • Check for leaks around your home and repair them. A dripping faucet or leaking toilet can waste hundreds of gallons of water each month
  • Take shorter showers. Keep your shower to five minutes or less.
  • When brushing your teeth, washing your face or shaving, turn the water off until it is time to rinse. 
  • Install high-efficiency shower heads, faucet aerators and toilets. Newer models require less water. 


TCEQ seeks stakeholder input on backflow prevention

From Texas Section of the American Water Works Association

The TCEQ will conduct stakeholder meetings across the state in January to solicit informal comments on rulemaking for 30 Texas Administrative Code (TAC) Chapter 334, Subchapter F, Landscape Irrigation - Backflow Prevention and Cross-Connection.

This rulemaking is the result of petitions approved at the Oct. 4, 2017, Commissioner’s Agenda. The petitions seek to amend acceptable methods for backflow prevention in 30 TAC 344.52, Installation of Backflow Prevention Devices, including:

  • eliminating authorization of double check valves,
  • adding spill resistant vacuum breakers as an allowable alternative,
  • including requirements for the use of in-line filters or strainers, and
  • changing terminology from backflow prevention “devices” to “assemblies” to align with 30 TAC 290, Public Drinking Water.

Additionally, the petitions seek to revise 30 TAC 344.50, Backflow Prevention Methods, to align current TCEQ rules with existing national and international standards concerning the health hazard classification of irrigation systems, the backflow assemblies acceptable for use in protection against an irrigation system, and the terminology used to refer to a backflow prevention assembly. 

Information on cross-connection and backflow prevention, a link to the current TCEQ rules, and copies of the Commission’s decision on the petitions can be found on the Landscape Irrigation Regulation Stakeholder page on the TCEQ’s website.

Stakeholder meetings are an opportunity for the public to provide informal comments to staff prior to the start of formal rulemaking. While staff will review all comments received, the TCEQ will not formally respond to any informal comments.
