Episode 23: Irrigation Efficiency with Kirk Pumphrey

Kirk Pumphrey grows 160 acres of almonds on Westwind Farms in Yolo County. He has been on a seven-year journey to finetune his operation, especially in the areas of irrigation efficiency and distribution uniformity. “In ‘13 and ‘14 the market was down, and a piece of property became available. I got through the planning of the orchard probably moving, I would say a bit quick in not doing as much research as I probably should have…. I quickly learned and understood the deficiencies of those decisions and reached out for help. - Kirk Pumphrey Through this process he has developed close relationships with researchers at UC Davis, local resource conservation districts (RCDs) and others. Pumphrey has been driven to find the latest research and best practices that work for him on his farm. Not only is he collaborating with UC Davis on multiple research projects, but he has also worked with Kevin Greer at the Tehama County Resource Conservation District to run distribution uniformity tests, and has found a way to remove boron from his water and sell it as a fertilizer to areas that are deficient. Given the last few years of severe drought, Pumphrey has explored flowmeters and the impact they have had on his water efficiency. “We'll find at the beginning of the year, the output of that well is “x.” We've already noticed by the end of this month of April that we're in right now, a difference that our well output already has. Consequently, runtimes are a bit longer and I'm sure as we progress through the season, the same thing's going to happen, and the water volume will change. You can't use anything that's theoretical. You've got to base it on gallons.” - Kirk Pumphrey In Today’s episode:Meet Kirk Pumphrey, an almond grower on Westwind Farms in Yolo County.Explore the journey he has taken towards collaborating with researchers and RCDs to best use the resources he has availableDiscover Pumphrey’s use and recommendation of flowmeter sensors to increase his water efficiencyLearn about his best practices in timing and application for pursuing grant money to help your operation be as efficient as possible without incurring extra expense“The volume of water in the world is not going to change tomorrow. It's a closed system and we have a management problem of that water. And we, as a society, need to understand how we are going to manage this better.” - Kirk Pumphrey ABC UpdateThere’s no easy year when it comes to farming in California, and as you just heard from Pumphrey, the journey to get it right doesn’t really have a final destination. Since 1973 the almond community has supported more than $89 million in research to improve farming practices. One of the many deliverables from this investment is a number of helpful research-backed resources that growers can access for free. Almond Board Senior Manager of Industry Relations and Communications Jenny Nicolau says a good place to start is almonds.com/growertools, where you’ll find a whole irrigation section with each tool listed separately and east to access. The page also contains educational videos from the irrigation station series that the Almond Board produced a few years ago. Growers can get more information about the tools and topics by accessing the
