A New Season of Growth
new peanut season is upon us. The start of the season brought in some unusually cooler temperatures and wet conditions but then the weather shifted to hot and dry rather quickly. The weather always seems to challenge farmers and provide lessons for each year on things to improve or change for future years. This time of year also brings a new season of growth for many who may have high school or college graduates. Some farmers may even be planting their very first peanut crop by their self. Recently I read a quote that seems fitting for this time of year. “Every new season of your life will be an opportunity for you to learn and grow. Don’t celebrate the good without celebrating the bad because they both work together to prepare you for the next season of your life.” Many times, we often talk about the good, celebrate the good and try to forget the bad. Well this past year has definitely been one of those trying times for many who may have lost loved ones due to COVID-19, businesses or other hardship. I don’t think this past year is one that will not be discussed for future years. In fact, there are many things we can learn from each other regarding coping with change, trying new things and getting back to the basics. At a time when many Americans were home trying to juggle working from home while teaching their kids, many of those families were looking for a way to source locally grown foods. Many tried their hand at victory gardens while others purchased food boxes from local farmers. All the while, I believe more individuals started remembering and thanking the American farmer for the abundant food supply available every year. Many times in agriculture we have opportunities to learn from some of our past mistakes at planting, spraying or even with irrigation. Let’s take this year to reflect on the bad and good times so that we can grow and learn for the future peanut seasons and be able to share our knowledge with future generations of farmers!

Peanut Allergy Treatment Provides Parents Hope
enry County parents, Caleb and Freda Bristow were heartbroken, yet determined after finding out their youngest son Sam, suﬀered from a peanut allergy. For some parents this information may seem frustrating and inconvenient but for the Bristow family it was very problematic. Caleb Bristow grew up on a peanut farm, manages a peanut buying point and also sells peanut trailers. Peanuts are an essential part of his everyday life. “I even had people joke- with me growing up in the peanut industry- and say oh wouldn’t it be funny if your kid has a peanut allergy,” Caleb says. About a year ago, when Sam was around six months old, Caleb and Freda started introducing Sam to peanut products. He had a few minor reactions to it, but Caleb wasn’t convinced his child could be allergic to peanuts. Having already been diagnosed with some food allergies, and after a trip to a pediatric allergist, the Bristow’s worst nightmare was confirmed. Sam was diagnosed with a peanut allergy at around nine months old. “I literally work for peanuts and now I have a kid who is allergic to peanuts,” Caleb says. Fortunately for the Bristow family, they knew that just living with the allergy wasn’t the only option like their allergist had suggested. Caleb, having also been the former executive director of the Alabama Peanut Producers Association, previously had the opportunity to meet with a doctor in Birmingham who was working on a groundbreaking treatment that essentially eliminates the peanut allergy from a person’s body.
Sam Bristow had a few minor reactions to peanut products at six months old but now through oral immunotherapy, he is able to eat up to a half teaspoon of peanut butter.
Joseph LaRussa, M.D. is a BoardCertified Allergy and Immunology Specialist in Birmingham, Alabama. With 22 years of pediatric allergy experience and having a child with peanut and tree nut allergies, LaRussa knows what it is like to be a parent of a food allergy child. He has discovered children with a peanut allergy can actually be desensitized to the allergy through oral immunotherapy. In January of 2015 a group of researchers from both London and the U.S. released a groundbreaking study which is now known as the Learning Early about Peanut Allergy (LEAP) study. The results of the study found that the introduction of peanuts into an infant’s diet, prior to 11-months old, reduced the prevalence of peanut allergy by approximately 70-80 percent (peanutallergyfacts.org). This study motivated LaRussa to conduct further research on how to help patients with peanut allergy.

During the Bristow’s first appointment the doctor said something that Freda says she’ll never forget. LaRussa said, “we want to dictate food allergies, not food allergies dictate the way we live.” “I almost cried… that was just like a sigh of relief. We can help him (Sam) with this, so he doesn’t have to live in fear,” says mother, Freda. Sam is far enough along in his treatments that the Bristow family no longer has to worry about having peanut products in the house. “After 16 weeks we have finally worked our way up to half a teaspoon of peanut butter,” Caleb says. By springtime, Sam should be able to enjoy a peanut butter and jelly sandwich. While this immunotherapy is not FDA approved, it has proven to be a safe and viable option for infants and children trying to overcome peanut allergies. For more information on how to safely introduce peanuts to your infant to help prevent peanut allergy, visit preventpeanutallergies.org. Since 2001, through the National Peanut Board, peanut farmers across the nation have earmarked more than $32 million of their own dollars into research and education about food and peanut allergies.

2021 IRRIGATION GUIDEBOOK
Selecting the Correct Sensor Threshold for Irrigating Peanuts
he standard recommended soil water tension trigger point for peanuts in sandy loam soil (most predominate soil type across southern Georgia), is 45 kPa. This value has been used in research for over the past six years and has aided in maximizing yields when compared to other irrigation scheduling methods. However, there is evidence (such as primed acclimation) that suggests the trigger level of peanut could be adjusted to better match the water requirement. Thus, this article aims to provide information on varied irrigation trigger levels to aid in maximizing yield. A two-year study was conducted at UGA’s Stripling Irrigation Research Park (SIRP) in Camilla, Georgia, under a variable rate lateral irrigation system with the main objectives of utilizing soil moisture information to determine the optimal timing or sensor reading for triggering irrigation on peanut on commonly planted varieties to Georgia and the surrounding region, in addition to evaluating the varied irrigation timing eﬀects on final crop yield. During both the 2018 and 2019 production seasons, plots were established at UGA’s SIRP under a variable rate lateral irrigation system capable of independently controlling water
applications within eight row wide by 42 ft. long plots. The field has a total of 27 plots, or enough area for nine treatments to have three replications each. Peanuts were planted during early to mid-May during both years, and soil water tension was monitored hourly. Daily irrigation decisions were made from the data collected at 7:00 a.m. each morning. WaterMark soil water tension (SWT) sensors were used to trigger irrigation at 20, 30, 40, 50, and 60 kPa. To bring this into perspective 20 is considered wet, 30, wetter than average, 40 is near optimal, 50 is near optimal, and 60 is dry. Yield was collected by harvesting the middle two rows from each plot. While statistically there were not diﬀerences between the diﬀerences within years there was a numerical trend of increasing yield as the soil water tension increased up to 50 kPa. Once the soil was allowed to dry beyond 50 kPa yield was reduced in both years. It should be noted that 32.7 and 19.7 inches of rain were received in 2018 and 2019 respectively. Independent of the total amount of rainfall the same trend of increasing yield up to the 50 kPa level then a reduction of yield once the SWT was kept drier was observed. This suggests that there is a penalty for

irrigating peanuts too early with too much water and for delaying irrigation, or not irrigating the crop with enough irrigation. The data strongly suggests adopting a soil moisture sensor, or more advanced irrigation scheduling method when scheduling irrigation on peanuts as both under and over watering them has shown yield reductions. While on the topic of over irrigating peanuts, another critical topic to discuss is the utilization of the Checkbook method. If followed without considering current environmental conditions the UGA Checkbook method can miss the irrigation target. This can happen by overor under- irrigating depending on current environmental conditions. However, typically the Checkbook method tends to over-irrigate. This can be seen during both 2018 and 2019, where the Checkbook method applied approximately double the amount of irrigation as the overall applied average. In both years the yield was lower than treatments with much less water applied. Higher amounts of irrigation with lower yields directly translates to decreases in Irrigation Water Use Eﬃciency (IWUE), which translates to reduction in profitability in most cases. Current environmental conditions such as rainfall, temperature, sunlight (solar radiation), and humidity should be considered when determining how much irrigation to apply via the Checkbook method in a given week. A week with cooler and cloudier weather will require less irrigation, while a week with lots of sunshine, high temperatures, and low humidity will require a higher than average amount of irrigation. The Checkbook method is meant as a guide, and was developed based on a long-term (15-year) average evapotranspiration value. Thus, these averages can miss the target if consideration to current conditions are not considered. Bਙ Wਅਓਅਙ M. Pਏਔਅ Uਉਖਅਓਉਔਙ ਏਆ Gਅਏਇਉਁ

2021 IRRIGATION GUIDEBOOK
The Importance of Pivot Uniformity and How to Interpret Mobile Irrigation Data by David Hall, UGA Extension Water Educator and Wesley M. Porter, Ph.D. Associate Professor and Extension Precision Ag and Irrigation Specialist
ssuming a center pivot is installed to the correct specifications, the eﬃciency and uniformity of this system will only deteriorate from installation forward. Flowing pressurized water over time will wear away orifice openings and splash plates. Proof is provided in the 10-year-old rotator plates in figure 1 below. Figure 2. Obvious drought stressed peanuts from lack of suﬃcient irrigation revealing visible “rings” in parallel circles from nozzles applying more water while other nozzles are applying less.
Figure 1. Rotator plates from a 10-year-old pivot with around 9,000 hours. The left plate is near the end of the pivot where flow is higher and the right one is near the first span where the flow is much lower. Notice the raised cut out on the heavy flow nozzle (circled in red) compared to the lower flow rate nozzle which will aﬀect spray pattern.
As an UGA Extension Water Educator, I have seen and uncovered some brain puzzling issues with center pivot irrigation systems. Sometimes it is very obvious to the eye (Figure 2) and sometimes it takes a flow meter along with in field measurements to identify a problem. Farming is an occupation that has very little, if any, downtime. Taking for granted that center pivot irrigation systems will be eﬃcient and apply water uniformly from year to year can be very costly. Many times, issues are not discovered until harvest season. Sadly, at harvest, after yield has been lost it is too late for correction. Mobile Irrigation Labs (MIL) are not anything new to the Southeast. Several agencies can perform one and programs to aid producers in
allowing them to audit pivots on their own can be provided. The University of Georgia Agricultural and Natural Resources Extension Service has been working to assist producers with audits for years now. Irrigation audits require a little time to perform and the weather must be conducive to complete the test, such as wind and temperature. Catch cans are measured oﬀ equally, usually every 20 feet, in a straight line from the center pivot point. The pivot is then operated applying 0.2 inches of irrigation across the buckets as you can see below. The flow rate is measured in gallons per minute, pressure noted, visual inspection of the whole system is observed which includes the end gun arc movement and noting any obvious leaks
Figure 3. A Mobile Irrigation audit being performed.

or abnormalities with any nozzles. I like to review the irrigation design of the system for comparisons to make sure the length, number of nozzles and data I am gathering matches the original design. Many times, an incorrect design due to improperly matching up the available flow, has led to blindly underwatering a crop. Simple rain gauges spaced along several spans can help verify if you are applying what the percent timer or controller is supposed to be applying. Surprisingly, I still see the old permanent black magic marker with an arrow pointing to a percentage saying “run here” or “.5” as in figure 4.
Figure 4. An example of a “marked” pivot for estimating approximately how much to apply and how long it will take.
By conducting an audit, a new application chart can be supplied for the pivot providing the farmer with the corresponding rates for each timer setting. The simple fact is that pumps and nozzles wear with time and decreased flow rates are inevitable. Charts need to be updated to ensure correct irrigation amounts are being applied. Looking at audits from a water conservation angle, a map showing potential water savings with end gun shut
2021 IRRIGATION GUIDEBOOK oﬀ on non-crop areas can be produced for an “average year” (Figure 5). Once an end gun shuts oﬀ, two things can be observed immediately. The pressure will increase and the flow will decrease.
Figure 5. An end gun map showing potential water savings on this field of peanuts using an end gun shut oﬀ.
Pumps are designed to pump a specific flow rate at a given pressure. If the flow is restricted and pressure is increased, the pumps ability to perform at peak performance is restricted, leading to lower flow. All pumps have a pump curve that show gallons pumped at a specific pressure. By not irrigating non-crop areas, water conservation of millions of gallons begins to add up rapidly. When UGA Extension performs a mobile irrigation lab audit, the graph in Figure 6 represents part of what is provided back to the producer. Figure 6 provides a foot by foot assessment of how uniformly a pivot is applying water down the length of the system. The X-axis is the measured application rate down the actual length of the pivot plus the water being applied by the end gun to the wetted perimeter. The Y-axis represents the amount of water caught at a given percent speed or in an amount of inches applied. Keep in mind, this graph is representing a line segment of a the entire application circle. As the pivot rotates
in a circle, each area that is applying too much or too little water is doing that all the way around the circle. This directly relates to acres aﬀected. The further down the length of the pivot you are from the center, the greater the eﬀect. As you can see in the graph below, a simple end gun adjustment on the end of this system (which aﬀects the highest number of acres), cleaning out partially stopped up nozzles and replacing nozzles that have malfunctioned could greatly improve the uniformity and distribution of water on this pivot. It is diﬃcult to visually see a nozzle that is partially clogged, but the catch can data shows it very easily. The life span of nozzles depends greatly on use and water quality, but a good rule of thumb is to plan to change nozzles at least every 10 to 15 years. So why is this important and what needs to be done next? The pumping cost to the producer will be the same whether they apply it uniformly or not. The main point here is the return on investment. If irrigation is applied non-uniformly in areas across the field, the crop will not yield well and areas over watered can lead to crop lodging, boll rot, disease, stuck pivots and possible erosion, while areas that are under-irrigated will most likely lead directly to yield loss. All leading to decreased revenue or “money left on the table.” Acres that can be aﬀected vary greatly depending on where your issues may appear along the system in conjunction with the system length. On a typical 100-acre irrigated field that may have 10 percent or less uniformity issues, this would equate to approximately 10 acres aﬀected. Remember, your inputs are the same but your income from potential yield loss can be reduced by half on those 10 acres.
Pivot uniformity is extremely critical if a farmer is planning to fertigate or chemigate too. Water is one of our most important natural resources and farmers, along with UGA Extension, strive to be eﬃcient and wise with our water through all kinds of technology. Moisture sensors, irrigation scheduling methods, remote monitoring, and last but not least regular maintenance on irrigation systems are just a few methods! Take the time to perform a uniformity test on aged pivots and address issues that can be addressed.

There are times when an audit can reveal some very interesting information. Everything from incorrectly installed nozzle packages, wrong nozzle packages, lack of flow rate needed and not to mention those pesky partially blocked nozzles that may be applying half the rate not noticed by the naked eye. If uniformity is in the 70 percent range with variations all along the pivot, it may be time for a retro fit kit. Always make it a point not to leave money on the table as mentioned before. Inspect and audit pivots to ensure every gallon of water pumped and applied is applied as uniformly as possible. Do not let poorly applied water from a center pivot be a limiting factor in your yields and profit. Contact your local UGA Extension oﬃce for more information on how to perform an audit on your farm, or arrange to have a UGA Extension representative conduct a Mobile Irrigation Lab free of charge.

Reinke and CropX Install Technology at Sunbelt Ag Expo Soil moisture monitors work with irrigation scheduling in research fields
wo leaders in precision agriculture, Reinke Manufacturing and CropX, have put down additional ‘roots’ in the research fields around the Sunbelt Ag Expo. During a recent training session for Reinke dealers, CropX illustrated how easy their field sensors were to install. Those sensors will now allow growers attending the expo in Moultrie, Georgia, an opportunity to see how they work with Reinke’s irrigation system to provide the world’s finest irrigation scheduling. Chip Blalock, executive director of the Sunbelt Ag Expo, says they are excited to try this new technology on their research farm and be able to showcase it to their farmers to use on their own operations. “Our partnership with CropX and Reinke enables us to demonstrate the latest technology in soil moisture sensing,” says Chip Blalock, executive director of the Sunbelt Ag Expo. “CropX’s new soil moisture sensors and the data that we derive from them further enhance our environmental sustainability by helping us put the right amount of water on a particular crop at the right time. This in turn optimizes our irrigation input costs while striving for maximum yields. All the while, allowing us to conserve our precious water resources.” Each day, Reinke dealers work along-side growers to optimize yields with precision irrigation application to help them save time and money. The partnership with CropX has given those dealers another tool to improve water application decisions. “This is a very important product for growers right now,” says Rob Mercer,

Coney Irrigation in Cordele, Georgia. “It allows them to accurately monitor their soil moisture and apply only the water they need. That will ultimately save them money by eliminating unnecessary watering and improving yields.” Working together with Reinke’s ReinCloud software platform, CropX soil monitoring sensors puts next-level crop control into growers’ hands. Each sensor leverages thousands of data points above and below ground – including soil health, crop behavior, precise weather patterns, topography maps and more – to maximize the performance of the Reinke irrigation system. “I’m so glad that we could help make these sensors available to the Sunbelt Ag Expo to let the growers in the area see how well they work with our pivots,” says Mike Mills, Reinke Southeast territory manager. “At Reinke, we know how important it is to provide growers with
technology that will have an immediate and lasting impact on their operation, helping them control their irrigation with power and precision.” During the installation, Jeﬀ Burton, CropX Southeast territory manager, talked with dealers and answered questions about how CropX sensor worked with diﬀerent crops, including corn, cotton and peanuts. “CropX makes irrigation management simple for the growers and their trusted advisors,” Burton says. ”Our hardware and software platform combined with our world-class agronomy team put everything you need in the palm of your hand to reduce irrigation costs and maximize yields by providing the crop with the optimal irrigation practices.” For more information on how Reinke and CropX work together to help growers improve their irrigation application, go to www.reinke.com/cropx.

Washington Outlook by Robert L. Redding Jr.
Chairman Bishop Raises Peanut EU Concerns with USDA Secretary The U.S. Peanut Federation (USPF) discussed with U.S. Congressman Sanford Bishop, D-Georgia, European Union (EU) non-tariﬀ trade barriers being applied to U.S. peanut imports. This involves increased levels of aflatoxin limits placed on U.S. peanut imports. It is important to note that these U.S. peanuts have passed the U.S. Department of Agriculture (USDA) aflatoxin testing protocol. According to industry experts, the U.S. peanut industry follows all EU sampling and testing protocols but still has many failed lots at their destination based on further sampling and testing. U.S. House Appropriations Subcommittee on Agriculture, Rural Development, Food and Drug Administration and Related Agencies Chairman Bishop raised this important peanut issue with USDA Secretary Tom Vilsack at a recent Appropriations Committee hearing. Secretary Vilsack recommended that the Oﬃce of the U.S. Trade Representative work with the peanut industry to resolve its EU concerns. In addition, U.S. House Agriculture Committee Chairman David Scott, D-Georgia, discussed the EU peanut issue with his counterpart in the EU Parliament. UPDATE: U.S. Trade Representative Katherine Tai testified before the U.S. Senate Finance Committee and the House Ways and Means Committee to discuss “The President’s 2021 Trade Policy Agenda.” Ambassador Tai’s testimony can be found at www.ustr.gov.
USPF Requests Continuation of Federal Aflatoxin Research Funding The U.S. Peanut Federation filed Fiscal Year 2022 appropriations requests for Aflatoxin Research at the National Peanut Research Laboratory and Fort Valley State University. Congress approved $1.5 million for the aflatoxin project in Fiscal Year 2021. Fiscal Year 2022 appropriations hearings are wrapping up for this year and the committees will soon start the mark-up process. The House Appropriations Committee is projected to complete its work in June.
U.S. House and Senate Committees Hold Additional Climate Hearings The U.S. House of Representatives held a hearing in the Conservation Subcommittee on “Title II Conservation Programs: Exploring Climate Smart Practices.” Subcommittee Chairwoman Abigail Spanberger, D-Virginia, opened the hearing with comments about the importance of using the Title II Conservation section of the Farm Bill as a vehicle for agricultural climate initiatives. “As we look to scale the adoption of conservation practices, there is perhaps no greater tool available than the Farm Bill’s conservation programs,” Spanberger says. “Title II programs provide much needed technical and financial assistance to encourage the adoption of cover crops, reduced and no-till management systems, and prescribed grazing systems — among many other climate smart practices. And we have seen firsthand these programs working in central Virginia.” Hearing witnesses included: Charles Edwin “CJ” Isbell Jr., farmer, Keenbell Farm, Rockville, Virginia, Kimberly Ratcliﬀ, ranch manager, Caney Creek Ranch, Oakwood, Texas, Keith Paustian, University Distinguished professor, Department of Soil and Crop Sciences, Colorado State University, Fort Collins, Colorado and James D. Johansson, president, California Farm Bureau, Sacramento, California. The U.S. Senate Agriculture Committee also held a climate hearing entitled “Federal, State, and Private Forestlands: Opportunities for Addressing Climate Change.” Chairwoman Debbie Stabenow opened the hearing by stating, “Mother Nature couldn’t have designed a more eﬀective mechanism for sequestering carbon and cleaning our air. America’s forests currently pull as much carbon dioxide out of the air every year as eliminating 54 million cars from the road according to the National Academy of Science. Climate-smart forestry policies oﬀer both tools to reduce carbon pollution and an important opportunity to develop new revenue streams for family foresters.” UPDATE: USDA has released a 90-Day progress report on Climate-Smart Agriculture. The entire report can be viewed at: https://www.usda.gov/sites/ default/files/documents/climate-smart-ag-forestry-strategy-90-day-progressreport.pdf
USDA Extends Supply Chain Comment Period The U.S. Department of Agriculture (USDA) Agricultural Marketing Service (AMS) is providing an additional 30 days for public comments on the notice for Supply Chains for the Production of Agricultural Commodities and Food Products published in the Federal Register on April 21, 2021. Comments are now due by June 21, 2021. USDA is extending the comment period to allow additional time to receive information valuable to the preparation of the report required by the Executive Order on “America’s Supply Chains.” During the first two weeks of the comment period, USDA received requests from representatives of critical supply chain activities asking for additional time to provide thoughtful and thorough feedback to this notice. Written comments in response to this notice should be posted online at www.regulations.gov. Comments may also be sent to Dr. Melissa R. Bailey at melissa.bailey@usda. gov.
