IrrigationAdvances Dealer View Desert land produces new growth in Egypt Q: What do you see for the future of irrigation in Egypt? Bahgat Abdelrhman Manager, Green Valley Ismailia City, Egypt Q: Where is Green Valley focusing its operations in Egypt? A. Our largest areas of growth are newly developed desert land. We draw water from underground, as well as from the Nile, for pivots and fixed-spray irrigation. Q: What are the main crops grown? A. Green Valley customers grow potatoes, peanuts, corn, barley, wheat, vegetables, alfalfa, sugar beets, spices, and some medicinal plants for pharmaceutical purposes. Crops grown under Zimmatic irrigation here in Egypt are used domestically and are also exported to nearby Gulf countries and Europe. A. There is a great deal of growth potential for new irrigation development throughout the country, especially for exporting crops like potatoes and peanuts to Europe. Plus, there are a lot of foreign and domestic investors interested in Egyptian agriculture. As far as crops go, we’re researching the advantages of using pivots to irrigate citrus crops. I have a customer who grows both potatoes and oranges. His potato pivot was positioned near his orange grove, and part of the pivot ended up watering the oranges. At the end of the season, he had much larger citrus yields in the areas near the pivot compared to drip irrigation. We will continue to explore irrigating citrus crops with Zimmatic center pivot irrigation.

Wall recently installed a Lindsay Watertronics VFD control panel on his 100 horsepower irrigation pump in Hamilton County, Neb. The VFD control technology is designed to save Wall energy, water and maintenance costs. “The variable frequency drive control technology is something new we are trying on our farm to reduce our cost of electricity,” Wall says. “Electrical costs are a major expense for us in running our irrigation pumps and systems.” In simplest terms, VFD control technology adjusts the speed of the electric motor on Wall’s irrigation water pump to match the specific demands of his irrigation system. Unlike a fixed single-speed drive, the Lindsay Watertronics VFD control technology saves energy by providing a “soft start,” gradually increasing the motor speed until it reaches peak operating speeds. Further energy savings are realized “With energy rebates from the power companies, VFD technology can pay for itself in less than five years. Plus, you have less wear and tear on your pumps and irrigation systems.” v FD t e c h n o lo g y p r e c i s e ly a n d e v e n ly m at c h e s pump output to i r r i g at i o n s y s t e m demand I 2 – Erich Williams, The Pivot Man the end of our corner arm is at about 30 pounds per square inch (2 Bars). Without VFD it can be as high as 70 pounds per square inch (4.8 Bars).” VFD p r ov i d e s simple, reliable and economic al control by the VFD’s ability to precisely and evenly match pump output to system demand. Lindsay’s local Zimmatic dealer, The Pivot Man in Grand Island, worked closely with Wall in designing and installing the VFD control panel. “There is lots of buzz and curiosity in our area about VFD technology,” says Erich Williams of The Pivot Man. “We have installed several VFD control panels on farms in our area this year and are working to educate growers about the benefits of this energy-saving technology.” Wall is using the Watertronics VFD control technology on a pump that supplies 800 gallons of water per minute (50.5 liters per second) to a pivot that irrigates approximately 150 acres (61 ha) of corn. The pivot includes a MAXfield corner system. “The VFD control panel was installed in June and we are still documenting the potential energy savings,” Wall says. “But the VFD control technology seems to be especially beneficial for a corner irrigation system because of the variability of water pressure at the end of the pivot. With VFD technology, the water pressure at Williams is working with Wall and other growers and local electric utilities in central Nebraska to fine-tune the VFD devices for maximum energy and water savings. “I am really impressed with these new VFD control panels,” Williams says. “With energy rebates from the power companies, VFD technology can pay for itself in less than five years. Plus, you have less wear and tear on your pumps and irrigation systems.” The VFD control panels are custom-designed and pretested at Lindsay’s Watertronics manufacturing facility in Hartland, Wisconsin. As VFD control technology continues to grow in popularity, The Pivot Man and Williams are helping to install the devices on area grain bins and grain bin towers, legs and drying systems. “The Watertronics VFD control technology works great for slowly ramping up electric motors. It’s less shock on the motor and the system. With a fixed drive irrigation motor, you’re basically pumping against a brick wall and there’s nothing you can do about it. VFD technology is changing all of that,” Williams says. The Watertronics VFD control technology can be installed on both new and existing electric motors.

The rebates amount to 20 cents per kilowatt hour saved. “A lot of growers don’t know about the VFD incentives but it’s starting to catch on as they see the benefits of this new technology,” Fuehrer says.

Mark Pye, managing director, doesn’t take that risk at his operation in Mallee, Australia. Steve Hall (left) of Hall Irrigation and Anthony Plum (right ), carrot farm manager, Parilla Premium Potatoes. I 4 He’s found that Zimmatic’s high-speed motor is the best way to irrigate his carrot crop because the first six weeks of germination is critical. A seven-tower pivot with a 43 RPM motor can complete a circle in under 13 hours, compared to more than 16 hours for a competitive system with a 34 RPM motor, which equals a 27 percent savings. Pye is using an 86 RPM motor running at 50 hertz which gives the motor a 71 RPM speed for even greater savings. Bumper crop Established in 1990, Parilla Premium Potatoes Pty Ltd. is a successful South Australian horticultural farm producing 60,627 tons (55,000 MT) of fresh produce a year. Managing Director Mark Pye moved from New Zealand in 1990 to grow potatoes for processing, and currently grows 3,000 acres (1,214 ha) annually, along with 1,000 acres (404 ha) of onions, 1,000 acres (404 ha) of Nance and Red Hot carrots and some cereal crops. Barley is used as a cover crop. While in New Zealand, he worked on his “market gardening technique” during holidays from school, and at age 18 he leased 30 acres (12 ha) of land from his family to grow Japanese pumpkins for export to Japan. This gave him the capital to buy into dairy cattle, which he sold to fund Parilla Premium Potatoes. • 20-25 people employed in the onion packing shed • Cool storage facility holds 3,306 tons (3,000 MT) of produce • Supplies the fresh potato market 365 days a year • Ships to large food retailers and other supermarket chains The high rate of speed helps resist the effects of sizzling temperatures and wind drift. “Center pivot irrigation offers a better distribution reliability, a clear harvesting path and is not affected by wind. Quality and yield are excellent compared to other irrigation methods,” Pye said. It typically takes four hours per half pivot with a VFD (variable frequency drive) pump over 65 acres (26 ha). One hundred and twenty acres (49 ha) are covered in 16 hours on a 95-degree (35 C) day. VFDs are important in the extreme weather conditions in midsummer, and take the wear and tear out of the driveline by ramping up and down and allowing higher hertz to be used. The soil type in this area is sand over clay and limestone, with an average annual rainfall of 12 inches (30.5 cm). Temperatures can reach up to 113 degrees (45 C) in summer with low humidity. Evapotranspiration rates can get as high as .55-.62 inches (14-16 mm) per day. Pye utilizes Online Control, easy-to-use computer software from “I haven’t lost any crops due to pivot downtime, and I’d tell other growers thinking about irrigating carrots with pivots to give it a go.” – Mark Pye Zimmatic, to manage 62 pivots that reduce labor costs and vehicle breakdowns, and help identify system failures to lessen the risk of crop damage in extreme weather conditions. “It only takes one person to look after 400 acres (162 ha).” “I haven’t lost any crops due to pivot downtime, and I’d tell other growers thinking about irrigating carrots with pivots to give it a go.” Contact Info: Hall Irrigation 1 Enterprise Road Lameroo, South Australia 5302 08-8576-3666 www.hallirrigation.com.au 5 I How sweet it is “Our Zimmatic pivots work great in helping the sugar beets to germinate properly and break up any crust that may be preventing emergence. You can’t do that with furrow irrigation.” I 6 – Kevin Hall Pivot irrigation is key to strong sugar beet germination Proper pivot irrigation management is critical to profitably growing sugar beets. Just ask Bridgeport, Nebraska, sugar beet grower Kevin Hall, who grows approximately 3,000 acres (1,214 ha) of sugar beets with pivots. Zimmatic pivots help Kevin Hall save water on his Nebraska sugar beet farm. Hall is also president of the Western Sugar Cooperative, which processes 135,000 acres (54,632 ha) of sugar beets in Colorado, Montana, Nebraska and Wyoming into pure granulated sugar that is sold throughout the United States (see "Fast Facts" to the right). “Pivot irrigation is absolutely critical during germination and emergence of the sugar beets,” Hall says. “Our Zimmatic pivots work great in helping the sugar beets to germinate properly and break up any crust that may be preventing emergence. You can’t do that with furrow irrigation.” Bill Pierce, co-owner of Midwest Farm Service, Hall’s local Zimmatic dealer, says sugar beet growers in western Nebraska and eastern Wyoming have come to rely on pivot irrigation to successfully manage their sugar beet crops. Hall also uses his Zimmatic pivots to apply fertilizer and some fungicides to his sugar beets. Because his land is spread over several miles in several counties in western Nebraska, Hall makes maximum use of his FieldNET web-based irrigation management and control system. “We have some pivots that are under electric load management and FieldNET works great when we have to stop and re-start the pivots. It saves a lot on labor costs,” Hall says. “We are in a water control area and the Zimmatic pivots help us conserve water.” With the recent introduction of Genuity™ Roundup Ready® sugar beets and new traits in sugar beet seeds, yields have increased substantially, according to Hall. Hall says sugar beet prices have been good to firm in recent years, making sugar beet production profitable.

As the third-generation owner of Kolk Farms, Ltd. in Iron Springs, South Alberta, Canada, Leighton Kolk has seen a lot of things improve over time. He witnessed his family farm’s progression from flood irrigation to hand-move and wheel irrigation before transitioning to pivot irrigation 25 years ago. In 2007, Kolk bought his first MAXfield Custom corner system – and he hasn’t looked back since. “MAXfield provides more uniform water distribution. I like that it I 8 cycles on and off, replicating a nice rain shower rather than a fierce thunderstorm,” says Kolk. The MAXfield Custom uses a pulsing sprinkler system to provide a more uniform application rate, often resulting in improved production. Other features include a hose-free joint that eliminates leaking, and a steerable arm that allows growers to bring additional acres under irrigation, increasing production without having to purchase more land. most of it “Every acre we leave idle is revenue lost. With MAXfield, we gain maximum efficiency.” – Leighton Kolk Continued > 9 I “I’m always looking for the next area to increase productivity and quality in a sustainable manner.” Because Kolk raises beef cattle on his farm, two-thirds of his land is dedicated to crops for his feedlot. The remaining third is made up of cash crops – canola, alfalfa, hybrid canola seed and wheat. Farmland is at a premium in Kolk's area, and MAXfield Custom’s steerable corner arm helps him make the most of available space by irrigating the land near his feedlot. “I’m able to dig further into the corners with MAXfield. Land is expensive here, so every acre we can put under irrigation production will pay off,” he says. “Every acre we leave idle is revenue lost. With MAXfield, we gain maximum efficiency.” Devan, Leighton and Jordan Kolk observe their MAXfield Custom corner in action. Kolk now has three MAXfield Custom corner systems and about 1,500 total acres (607 ha) under irrigation. Land in his area is trading at $5,000 USD per acre, especially land close to intensive livestock operations. Megan Kolk and friends riding in the feedlot.

Unmatched Water Uniformity Under Water Kolk Farm staff use Zimmatic’s MAXfield Application Planner (MAP) software to monitor the farm’s custom irrigation plan and track water usage. Staff members also utilize the FieldNET Wireless Irrigation Network to remotely start, stop, monitor and adjust pivots to increase overall efficiencies. “We manage all aspects of our operation with detail, keeping maximum potential in mind,” Kolk says. “Whether beef, grain, silage, equipment or trucking, we try to focus on high quality, safety and maximized potential. Top quality equipment, good planning and management, along with the latest technology, allows us to take our operation to the next level.” And when it comes to staying on top of the latest advances in technology, he turns to New-Way Irrigation, Ltd., his local Zimmatic dealer. “New-Way and Zimmatic seem to be on the leading edge of technology and equipment, such as precision irrigation and irrigation management and control,” says Kolk. Established in 1976, New-Way became a Zimmatic dealer in 1981. The South Alberta dealership has locations in Lethridge, Taber, Brooks, Strathmore and Bow Island. New-Way has supplied Kolk with seven Zimmatic pivots, as well as his three MAXfields. “Kolk is a good farmer. He’s very progressive and likes to keep up-todate on the latest technology and equipment. He takes the time to analyze key areas of his operation to make it more productive and profitable,” says Bryan Smith, a Over Water The AccuFlow water application package offers uniform water patterns. This patented technology allows for pulsing of sprinklers over critical parts of the field, eliminating dry areas as corner extends and overwatering when corner is tucking in. spokesman for New-Way. “The MAXfields help him pick up additional acres right near his operation for silage and for manure applications.” Kolk Farms began with Kolk’s late grandfather, Jan, who emigrated from the Netherlands after World War II. The farm was then taken over by Kolk’s father, Albert, who still lives in Alberta. Kolk’s wife, Elinor, and children, Jordan, Devan and Megan, are actively involved in the operation, and son Jordan is studying agricultural business at the University of Saskatchewan. “I’m always looking for the next area to increase productivity and quality in a sustainable manner,” Kolk says. Going forward, Kolk is certain of one thing – he will be installing more MAXfields.

PROTHEROE PTY LTD • Fourth-generation Australian farmer • Farms with his father, Colin Protheroe • In addition to rice, raises approximately 14,000 acres (approximately 5,600 ha) of wheat, canola, corn and grain sorghum • Rice marketed through SunRice growers cooperative • Local Zimmatic dealer: Flow Smart Pty Ltd, Griffith, NSW, Australia Saving Water with Pivot Irrigated Rice Brian Protheroe is a fourthgeneration Australian farmer who has been growing flood irrigated rice since 1995. But because of water shortages caused by recent dry years and the bullish price of rice, Protheroe decided to grow rice with efficient Zimmatic center pivot irrigation. CHALLENGE Protheroe had lots of experience raising traditional flood irrigated rice but little knowledge of growing rice under pivot irrigation. He did his research on pivot irrigated rice, including a trip to the United States to visit the Michael McCarty rice farm near Osceola, Arkansas. McCarty’s successful experiences raising rice under pivot irrigation I 14 were documented in a study showing substantial water, labor and energy savings and yields on par with flood irrigated rice. He planted two varieties of rice: Quest, a short-season, short-grain variety, and Amaroo, a longseason, short-grain variety, on 74 acres (30 ha) of land known locally as the Glen Ayre Farm. “I wanted to grow two different varieties with two different maturities in order to establish which variety was better suited for pivot irrigation.” Groundwater is the main source for his four Zimmatic center pivot irrigation systems, but Protheroe plans to add more pivots and pump stations to access water from a nearby river. Protheroe used a large 60-foot (18.3 m) planter to plant the rice, something he had previously not been able to do because of the dikes and berms that are used in flood irrigated rice fields. SOLUTION The Zimmatic rice pivot on Protheroe’s farm is 991 feet (302 m) long and includes six towers. The new pivot was equipped with a Nelson S3000 Yellow Plated Spinner sprinkler package, which applied fine droplets of water “like a good steady rain,” Protheroe said. The rice pivot was outfitted with Lindsay’s Z-TRAX tracking system and three-wheel drive tubes for improved traction and flotation. “The Lindsay tracking systems helped enormously,” he said. Lindsay’s Z-TRAX tracking system provides improved flotation and reduced rutting on Protheroe’s pivot irrigated rice. Because pivot irrigated rice can be planted on sloped fields of up to 30 degrees and doesn’t require costly field-leveling, dikes and canals, Protheroe was able to plant his rice on ground that had been in wheat the year before. “Not having to do dikes was key and really convenient, especially for my operation. We have large equipment, and I was able to go right into the field with our large seeder. With dikes and berms, I couldn’t do that,” Protheroe says. Fertilizer was applied through the Zimmatic pivot, a tractor spreader and an airplane. Protheroe was extremely pleased with weed control in the pivot irrigated rice. “One of the many benefits of rice production under a pivot is the ability to apply herbicides using existing equipment such as sprayers,” says Bryce Yates, managing director at Flow Smart, Protheroe’s local Zimmatic dealer. “With flood irrigation, this has to be done by airplane, which is much more expensive.” RESULTS Protheroe’s short-season rice variety yielded 195 bushels dry per acre (9.8 MT/ha), with some sections yielding up to 297 bushels dry per acre (15 MT/ha). The long-season rice variety yielded 105 bushels dry per acre (5.3 MT/ha). “I planted the short-season rice variety because the nights can get cool in our area around the end of December through mid-January, which can damage yield when the rice is heading. As it turned out, yields on the short-season variety were outstanding. I was very pleased with the yield on the short-season rice.” Protheroe conservatively estimates using 40 percent less water growing pivot irrigated rice compared to flood irrigated rice. Benefits of Pivot Irrigated Rice Vs Flood Irrigated Rice • Lower operating costs • Requires less water • P recision application of fertilizer and chemicals • No dikes or ground leveling • A ble to use larger equipment in rice fields • Plant and harvest sooner • O ption to rotate rice with multiple crops • A bility to grow rice on land previously not suitable for flood irrigated rice Brian Protheroe conservatively estimates using 40 percent less water growing pivot irrigated rice compared to flood irrigated rice. Protheroe plans to continue growing pivot irrigated rice, depending on how dry it is in his area and the market price of rice. More Info: For more information, visit www.ecorice.net.

Breeding for drought tolerance in rice, as well as innovative production systems, will be required to address water scarcity as it relates to rice production. One such water-saving irrigation system is the center pivot. Research is underway to evaluate and adapt center pivots to rice production. The basis for this research is threefold: to reduce the water required to produce rice, to expand the geographic area suitable for rice production, and finally, to reduce the cost of production by automating irrigation operations and fertilizer/ chemical applications. Center pivot sprinkler systems have many advantages over other forms of irrigation. Center pivots apply water more uniformly to fields than do flood or furrow irrigation. Since water outflows are lessened, pumping requirements are reduced, allowing farmers to save on both water and energy. Moreover, accurately metered fertilizers and chemicals can be applied through the center pivot with the same high efficiency as the irrigation water. This can significantly reduce labor and application costs. The loss of fertilizers and chemicals to leaching and runoff is minimized, thereby increasing input efficiencies and reducing potential environmental impacts. In-season nutrient application through fertigation enables better plant utilization of nutrients because applications can be timed to match the plant’s nutritional requirements. Center pivot systems perform well on sloped fields, eliminating the cost of expensive land leveling operations. Additional cost savings I 16 Irrigating rice with center pivots reduces water applications from 28 percent to 50 percent compared to conventional flood methods. can be realized from reductions in labor and expenses for heavy tillage, puddling, canal construction, surface smoothing, and check construction/ maintenance. conventional flood methods, while maintaining or improving rice yields. Reported yields from these studies have been between 160-200 bushels per acre (8-10 MT/ha). Expansion of rice ground without expensive land development can occur by using center pivot systems. Areas previously unsuitable for rice production due to topographic or soil texture constraints may now be considered for rice production. In addition, established paddies are suitable for rice production, but rotation to other crops is difficult because puddling operations destroy soil structure to maintain flood water. Use of center pivots will improve crop rotation options for healthier crops and soils while providing farmers more flexibility to respond to changes in markets, weather, and other conditions. A number of factors have to be taken into account when considering the use of center pivot systems for rice irrigation. The use of blast resistant rice varieties is essential, as overhead sprinkler systems will regularly wet the rice canopy. Increased dependence on herbicides will also occur without flood water to keep weeds in check. Herbicide and fungicide programs will have to be carefully monitored. The cost of these programs should be offset by reduced production and pumping costs, however. Research performed in the United States and Australia has shown that irrigating rice with center pivots reduces water applications from 28 percent to 50 percent compared to Center pivot sprinkler systems may not be applicable to every field and every situation, but the expectation is that the advantages of center pivot sprinkler irrigation can be successfully adapted to widespread rice production.
