Patience on Irrigating Almonds

When To Start Irrigating Almonds

 

By Tim Hammerich, with the AgInfo Network

When to start the irrigation on those almond orchards? Most growers want to get out there early to get the trees the water they need and to apply nitrogen through fertigation. However, there are risks associated with starting irrigation too early. This according to Dave Doll, who spent 10 years as a UC Farm Advisor in Madera County and is currently managing a farming operation in Portugal.

“The risks you have about starting the irrigation season too early is that you apply too much water that reduces the amount of oxygen within the root zone that depletes the ability for the tree to develop feeder roots or find feeder roots, which help with nutrient and water uptake,” said Doll. “So as such, what we would recommend and what still is a recommendation from my perspective and what we’re doing on an operation here, is to evaluate these trees for water demand in the spring before we start our application.”

“And this can be done through the use of a pressure chamber, which measures stem water potential, or even watching soil moisture probes to make sure that you’re getting a depletion in your top two feet of in soil moisture before you start applying in irrigation,” noted Doll.” And this in essence, will help you have better water management or more resiliency in your water management as a tree continues to grow and the temperatures pick up.”

Calif. Profs Win Irrigation E3 Leader Awards

Irrigation E3 Leader Awards Go to Two California Faculty

The Irrigation Foundation has named 15 outstanding students and faculty as winners of the 2015 Irrigation E3 Program. The Foundation selected two faculty 2015 Irrigation E3 Leaders, both in California, Florence Cassel, Fresno State and Tim Ellsworth, West Hills College Coalinga.

This year’s class of faculty and students will receive an all-expenses-paid trip next week to the Irrigation Show & Education Conference, Nov. 9 – 13, in Long Beach, Calif.

Founded in 2012, the E3 program provides students and faculty with exposure, experience and education in the irrigation industry. Academics nominate outstanding students for consideration as E3 Learners and/or apply to become E3 Leaders themselves.

To qualify to apply for Irrigation E3 Leader status, an instructor must be teaching, or will be teaching within the next six months, irrigation-related coursework at a North American community college, university or similar institution of higher learning. Prior winners may not reapply.

Chosen faculty will have the opportunity to participate in education classes, industry sessions and networking events. Working with academics is essential to the Foundation’s mission of attracting people to careers in irrigation by supplying the irrigation industry with educated professionals. Faculty members help shape the future career paths of their students and keeping instructors up-to-date on the latest and greatest in the irrigation industry is a must. 

“This is the fourth year of the program, and the Foundation is sending a record number of students to the show,” said senior foundation manager Janine Sparrowgrove. “We are excited to give the students and faculty the opportunity to attend classes and gain exposure to industry companies and technologies.”

Florence Cassel Sharma, Assistant Professor Irrigation/Water Management, Jordan College of Agricultural Sciences and Technology, Department of Plant Science, California State University, Fresno researches optimizing water use efficiency through low and deficit irrigation practices, improving irrigation scheduling, and utilizing remote sensing techniques for water resources management, crop water use, and soil salinity assessment. Assistant director of research of the Center for Irrigation Technology, Sharma is a recipient of the 2009 Outstanding Research and Scholarly Activity Award for the Jordan College of Agricultural Sciences and Technology.

Tim Ellsworthagriculture technology instructor at West Hills College Coalinga, researches primarily soil science with a focus on precision agriculture and nutrient management. He currently serves on the advisory board for the Canadian Biochar Consortium.

Prior to West Hills, Ellsworth was a professor and faculty director of the online master’s program for the Department of Natural Resources and Environmental Science at University of Illinois, Urbana-Champaign, a soil scientist with the USDA U.S. Salinity Laboratory, a visiting faculty member at the Centre for Water Research, Department of Civil Engineering, University of Western Australia in Perth and a senior scientist performing hazard assessments and hazard evaluations for the U.S. Army with regard to management of the U.S. Army Chemical Weapon Stockpile.
