Author: RDO Water

Year after year, the Southwest Ag Summit continues to be a premier ag industry event that attracts professionals and students from Arizona, Southern California, New Mexico, and Northern Mexico. Whether it’s the field demos or exhibitor show, the panel discussions or breakout seminars, or even the always-anticipated breakfast burritos or the always-sold-out Harvest Dinner, this annual event provides education, enjoyment, and the opportunity to see longtime colleagues and make new connections.

The Southwest Ag Summit is February 22-23 at Arizona Western College in Yuma, AZ. RDO Water in Yuma has been involved for several years. Especially in the past few years, the team has established itself as a leader in technology and become one of the most anticipated live demos at the event. This year’s demo is no exception, as the team is highlighting both soil moisture management tools and UAV technology.

An automatic moisture sensor will be displayed, with explanation of how such tools factor into an irrigation management strategy. The team will also discuss the use of drones in agriculture; specifically, using aerial imagery to identify areas of field stress, drought, or unhealthy field conditions, and the opportunity it provides growers to respond to and adjust operations quickly to minimize yield loss.

In addition to the live demo, RDO Water is sponsoring Thursday morning’s keynote panel, “Connected by the Colorado River,” at 7:30 a.m. The panel includes Chuck Cullom, Central Arizona Project; Tom Davis, Yuma County Water Users Association; and Dr. George Seperich, Arizona State University. A Water Panel Breakout will follow at 9:30 a.m.

Both RDO Water and RDO Equipment Co. will have booths in the exhibit area. Throughout the duration of the event, team members will be available to meet with customers, answer questions, and discuss the companies’ total solutions approach to agriculture equipment and irrigation.

Drip Irrigation Study Shows WUE Improvement

Study evaluated drip system distribution uniformity in key produce regions of California California_Drip_Irrigation

Author: Hank Giclas, Western Grower & Shipper

Water use efficiency has long been a priority for produce growers in the United States, but with diminishing water resources there has been a renewed urgency to improve efficiency in drip irrigation systems.

Western Growers, in concert with JR Simplot Water Services and The Toro Company, recently concluded a study to evaluate distribution uniformity in drip irrigation systems in key produce regions in California, including both the Oxnard Plain and the Coachella Valley.  This study was done in cooperation with Western Growers members who were interested in water efficiency and will be published soon to provide useful information to those operating drip systems.

An irrigation system’s uniformity of water distribution or distribution uniformity (DU) is a key measurement of a system’s water use efficiency.  If water is not distributed evenly or uniformly on a field, areas receiving less acre-feet of water may have poorer plant health and reduced crop yields.  Conversely, to compensate for unequal distribution and avoid reduced yields, the system must over-irrigate.

DU, expressed as a percentage, is considered outstanding when above 90 percent, as good between 70-90 percent, and poor when it is below 70 percent.  Operating with a DU above 90 percent makes good economic sense in that DU correlates closely to crop yield and reduces costs related to increased water use, which includes the water itself, energy to power the system, and often fertilizers and other chemicals run through drip systems.

These increased costs can be significant.  For example, an irrigation system operating at 75 percent DU versus 85 percent DU can use more than twice the water, three times the fertilizer and increase energy cost by three times.  In addition to increased costs, poor DU also impacts yield revenue.  A study in 2014 (J Anshutz, “Retrofitting your irrigation system for success and profitability”) assumed an average yield of 2,500 pounds per acre and a crop value of $3 per pound.  In a field with 85 percent DU, the author estimated a per-acre revenue loss of $188 due to DU degradation, while in a field with 75 percent DU, the loss grew dramatically to $563 per acre.  These numbers increase substantially as DU further degrades below 70 percent, demonstrating a real impact on the bottom line for growers using poorly designed and maintained irrigation systems.

The Winners, Losers of El Nino in the West

While it hasn’t lived up to the full hype, El Nino has been good for Arizona and California

ElNino-California-ArizonaAuthor: Cary Blake, Western Farm Press

El Niño-related rain and snow falls last fall, winter, and early this spring have been on the sporadic side. Yet we should be (and are) thankful for the fallen moisture from the heavens. The Pacific Ocean-based warmer water phenomenon tossed more than a couple of buckets of rain and snow at California and Arizona – both facing severe drought.

Portions of California were blest with a decent version of the much prayed for (and overall delivered) “March Miracle” which will benefit farms, ranches, and others. Yet the 2015-2016 El Niño version failed to live up to its hype, as one media outlet called it a potential ‘Godzilla’ El Niño.

The weather folks, as did farmers and ranchers, certainly wanted a behemoth El Niño, yet part of the weather pattern lost its strength once it moved inland from the warmer ocean waters in the southern Pacific where it began.

Initially some thought that this El Niño would leap over most of California and begin dumping wetness on Arizona, followed by moisture in the southern-most states to the east.

Arizonans were ecstatic when rare El Niño rains actually began late last spring into the early summer, very rare moisture in the low desert. Even the summer monsoon season in the Grand Canyon State blossomed into a near gully washer in some areas, tied in part to El Niño.

Afterwards, portions of California received hit-and-miss liquid and frozen manna from the heavens. Good rains in Arizona in early January boosted crop hopes. Yet as I pen this, central Arizona has remained high and dry since late January (two months ago).

Warm weather and clear skies parched thoughts of a wet February in both states. A journalist from a major California newspaper proclaimed El Niño a dud – a.k.a. caput. Yet a week or so later in early March, meteorologists were all high-fives as a major weather front developed – and targeted its downpours on California. Arizona was left high and dry.

Many Californians have enjoyed the timely rains as reservoir levels have risen, while entirely too much water, for political and regulatory reasons, have drained into the ocean – a disgusting sight for water-starved agriculture.

Overall, El Niño turned out positive. Let’s hope it has a storm or two left this spring.

RDO Water Releases Micro-Sprinkler Study Results

The benefits of micro-sprinkler irrigation for strawberry growers
Author: Danilu Ramirez, CCA, PCA, RDO Water RDO-Water-Micro-Sprinkler

Beginning in October of 2014, RDO Water participated in a 10-month research study with the University of California Agriculture and Natural Resources Cooperative Extension to evaluate the potential of micro-sprinklers in strawberry production. The study was conducted at Manzanita Berry Farms in Santa Maria, CA.

Study Overview
To begin the study, a block of strawberry was divided into two parts:
• East half set up with grower-standard solid-set aluminum pipe sprinkler irrigation design for establishment
• West half set up with a micro-sprinkler irrigation design throughout the season

Each block was planted on Nov 6, 2014. Prior to planting, drip tape was installed in the beds and was the main method of irrigation throughout the duration of the study, the 2014-15 growing season.

Research was conducted periodically throughout the growing season. Upon conclusion of the study, results were compiled and shared by Surendra Dara, PhD, DAIT, Strawberry and Vegetable Crops Advisor and Affiliated IPM Advisor for UC Cooperative Extension. Read the complete report in his blog post.

Below is a summary of key takeaways and primary benefits of the micro-sprinkler irrigated field in four primary areas:
Water Savings; Energy and Labor Efficiency; Disease and Pest Control; Pesticide Reduction

Additional Note: Both fields produced an overall healthy crop comparable in total marketable yield.

Water Savings
Study Summary: Micro-sprinklers reduced total water usage and applied it more efficiently.

Reduced water usage during establishment
• Approximately 32% of water savings in just three weeks compared to solid-set aluminum pipe
• Micro-sprinklers delivered 81,600 gallons of water per acre during establishment vs 120,000 gallons of water per acre for aluminum pipe
• Micro-sprinklers saved nearly 40,000 gallons of water per acre during establishment

Efficient water application
• Micro-sprinklers apply water in a smaller droplet size that doesn’t bounce off plastic mulch
• More water goes directly to the plant
• Less run-off
o *Added benefit of reduced nitrate loading risk, potential to reduce Waterboard requirements

Energy and Labor Efficiency
Study Summary: Micro-sprinklers demonstrated significant energy and labor savings.

Efficient by design
*Micro-sprinkler irrigation systems don’t require constantly moving cumbersome aluminum pipe
• No pipe for crews to navigate during harvest, weeding, etc.; low-profile micros do not get in the way
• No pipe to move when tractors are in the field spraying, cultivating, etc.

Energy savings
• Low pressure system: Only 30 psi needed to deliver water through the system
• Typically better Distribution Uniformity compared to aluminum pipe

Efficient crop production
*Micro-sprinklers produced less unmarketable fruit
• Plant energy goes into producing good fruit
• Saved money, time and energy from harvesting unprofitable product
• Better conditions for crews, faster moving through the field, less time spent cleaning plants

Additional Notes: Marketable berry yield data was collected two to three times per week, from February 7 through June 12. The micro-sprinklers produced nearly 1,500 fewer unmarketable berries per plot while keeping up with total yield compared to the standard aluminum pipe sprinkler block.

Disease and Pest Control
Study Summary: A common misconception is that micro-sprinklers promote disease; on the contrary, they suppress it. They also create an ideal environment to control pests like spider mites, and foster good beneficial insect populations.

Disease Control
*Powdery mildew severity was tested twice, in April and again in June
• Both tests showed significantly less mildew in micro-sprinklers

*Botrytis fruit rot was tested once per month in March, April, May and June.
• Micro-sprinklers showed less severe Botrytis fruit rot initially
• A significant difference was seen three days after harvest samples were collected
• In Micros: Easy to visually see much less rotten fruit being culled and thrown into the furrows

Pest Control
*Micro-sprinklers create a humid environment
• Spider mite webbing cannot form in high humidity
• Mites cannot thrive due to lack of dusty conditions, micros fine mist keeps dust off leaves
• Water stress prevention helps suppress populations of two spotted spider mites and boosts overall plant health
• Fosters good beneficial insect growth – less money is spent on releasing and establishing Persimilis as they thrive in humid conditions
• High humidity is needed to ensure Persimilis egg hatch

Pesticide Reduction
Study Summary: Micro-sprinklers offer more efficient and safe pesticide control, as well as the option for pesticide-free control.

Humidity Control
*As mentioned earlier, micro-sprinklers create a humid environment, not conducive to spider mite growth, allowing pest control via water vs. traditional pesticides
• High humidity environment is created by running micros at frequent short intervals per field conditions
• Use of humidity is environmentally sustainable and does not contribute to pesticide resistance as do conventional miticide sprays
• Humidity can be used as an organic method of spider mite control or as an aid in a conventional system
• As humidity strengthens persimilis counts, they also work to control spider mite hot spots

Pesticide Application
*Direct application of several types of pesticides via chemigation through the system
• More efficient, safe application
• Eliminates need for helicopter sprays; rainy winters, when furrows are too muddy for tractors to spray, micros can be used as a foliar applicator
• Per labels, fungicides, pesticides and fertilizers can be applied via micros as a foliar spray

Overall Study Summary
Micro-sprinklers have a long list of benefits that have been proven to be statistically significant through RDO Water’s trial work with the UC Extension. Water and energy savings during establishment are of high importance as the drought continues to affect California growers. Using a low pressure energy efficient system that saves more than 30 percent water and concurrently helps reduce pesticide use while promoting beneficial insect populations might sound too good to be true but it’s a reality. Labor savings, disease suppression, and less unmarketable fruit include even more benefits. Micro sprinklers are influencing strawberry growing practices now and will continue to make an impact in the years to come.
