As a Peace Corps volunteer in Niger in the early 1980s, Dahlberg was intrigued by sorghum, a staple food being cultivated by the country's vast population of subsistence farmers.
“I was impressed with the fact that sorghum was so drought tolerant,” Dahlberg said. “Nigerien farmers relied solely on rain for their sorghum and millet crops.”
Upon returning to the U.S., he earned a master's degree at the University of Arizona and a Ph.D. at Texas A&M, where his research focused on sorghum. He worked with the USDA Agricultural Research Service in Puerto Rico for 7 years and then spent the next 10 years as research director with the National Sorghum Producers in Lubbock, Texas.
When Dahlberg took the helm of the 330-acre UC agricultural research center in 2010, he and colleagues at the UC West Side Research and Extension Center and at UC Davis began conducting sorghum forage variety trials. Sorghum wasn't new to California. In the past, it had mainly been used for animal feed. But Dahlberg believed the crop's adaptability – excellent for forage, biofuels and gluten-free human food – offered the grain a rosy future in the Golden State.
"With our research, we have provided California farmers who are thinking about growing sorghum access to locally generated, research-based information to help them make the decision," Dahlberg said.
In 2015, Dahlberg and UC Berkeley specialist Peggy Lemaux launched a sweeping drought research project at KARE. The five-year study, funded with a $12.3 million grant from the Department of Energy, researched the genetics of drought tolerance in sorghum and how soil microbial communities interacted with sorghum roots to battle drought stress.
A journal article published in Proceedings of the National Academy of Sciences in 2018 presented the first detailed look at the role of drought in restructuring the root microbiome. The plant switches some genes on and some genes off when it detects water scarcity and access to water.
“That has implications for feeding the world, particularly considering the changing climate and weather patterns,” Dahlberg said.
In recent years, Dahlberg helped reestablish tea research at Kearney, initiated nearly 60 years ago in a study funded by Thomas J. Lipton, Inc. At the time, Lipton was seeking to grow tea for the instant tea market. When the Kearney tea research program was scrapped in 1981, a researcher had a handful of the best tea clones planted in the landscape around buildings at Kearney.
Those shrubs became the basis for a new tea research trial planted at Kearney in 2017 with UC Davis professor Jackie Gervay Hague to determine whether drought stress impacts the production of phenolics and tannins in the tea.
“We know we can grow good tea here and we can grow high tonnage,” Dahlberg said. “We want to determine if we can do that on a consistent basis and whether we can improve tea quality through irrigation management.”
In retirement, Dahlberg plans to relocate to Lake Ann, Mich., to be close to family. UC Cooperative Extension irrigation specialist Khaled Bali will serve as interim director of the UC Kearney Agricultural Research and Extension Center.

The historic Faulkner Farm, a 27-acre farm near Santa Paula, is for sale. The property, which houses the UC Hansen Agricultural Research and Extension Center, is listed at $3.7 million by the University of California Agriculture and Natural Resources.
The property on the corner of Telegraph Road and Briggs Road includes a 126-year-old Queen Anne Victorian house, a 134-year-old large red barn and a smaller barn built in 1982 for a Budweiser commercial. An orchard features an extensive collection of avocado varieties as well as a collection of tropical and sub-tropical trees including various citrus, banana, guava, mango, passion fruit, persimmon, papaya and fig.
UC acquired the Faulkner Farm in 1997, under the leadership of Larry Yee, who was director of Cooperative Extension in Ventura County at the time. The purchase was made with an endowment from Saticoy farmer Thelma Hansen, who passed away in 1993, for agricultural research and education activities in Ventura County.
Due to increasing maintenance costs for the historical buildings at Faulkner Farm and limited acreage for agricultural research, the Hansen Advisory Board along with agricultural stakeholders in the county recommended that UC ANR divest all or part of the property to honor the terms of the endowment. For over a decade, previous boards have recommended the sale to redirect the funds from maintenance of the historical landmark to support research and outreach for better fulfillment of the directives of the UC Cooperative Extension mission and enhance service to the Ventura County community.
“Now, more than ever before, we need to really expand our ability to find solutions for the challenges that agriculture faces: pests, diseases, climate change and more,” said Glenda Humiston, University of California vice president for agriculture and natural resources. “Enhancing research is critical to the future of agriculture for this region.”
The university will lease back a portion of the land for 18 months to complete active research projects and allow for continued UC Master Gardener Program activities at the site during the transition to the new location for its UC Hansen Agricultural Research and Extension Center.
“We are committed to having a UC Research and Extension Center in Ventura County, with more acreage to facilitate research on a wider range of crops and cropping systems, and better facilities for research and education,” said Mark Lagrimini, UC ANR vice provost of research and extension.
UC ANR is currently seeking a new location in the county.
“We are looking for 40 to 70 acres on the Oxnard Plain, ideally near potential partners and collaborators and suited for row and permanent crops,” said Annemiek Schilder, director of UC Cooperative Extension in Ventura County and the Hansen Agricultural Research and Extension Center.
“I am greatly saddened to learn that the University of California has decided to sell the Faulkner Farm, site of the Hansen Agricultural Center,” said Yee, the former director of UCCE in Ventura County and UCCE advisor emeritus. “In the beginning, we had every hope that the center would grow and prosper and serve both the needs of the agricultural and larger communities well into the future.”
Research at the facility focuses on improving crop productivity, irrigation, biocontrol of pathogens and pests, novel pruning techniques, and the introduction and evaluation of promising crop commodities. Additional research activities focus on issues in small-scale urban agriculture and organic farming.
UCCE advisors extend research results to local growers during field days and workshops at the site. Master Gardener volunteers maintain a demonstration garden, where they offer workshops for community members. Year-round 4-H agricultural literacy programs for students in grades K-12 include farm field trips, classroom outreach, an after-school Student Farm, and a Sustainable You! Summer Camp. The students learn about Ventura County agriculture, nutrition, cooking and sustainability.
“The Faulkner Farm has been such an important landmark and has made invaluable contributions to the life and well-being of the community,” Yee said. “Countless families, school children, teachers, Master Gardeners, researchers and other scientists have passed through its gates to enjoy learning about the importance of agriculture, how things grow and all the interrelationships between healthy soil, food and humans.”
Sales of property owned by the Regents of the University of California are governed by The Stull Act, which requires a sealed bid process. Bids are scheduled to be opened and reviewed in mid-November by the university.

UC ANR experts available to comment
California farmers stand to benefit from the addition of more commodities now covered by the USDA Coronavirus Food Assistance Program, say UC Agriculture and Natural Resources experts. Yesterday (Aug. 11) the U.S. Department of Agriculture expanded eligibility and extended the deadline to apply to Sept 11.
Farmers of aquaculture, nursery crops and flowers, sheep and specialty crops such as dates, dragon fruit, nectarines, pomegranates, pumpkins and many other specialty crops grown in California are now eligible for financial assistance to help keep their operations afloat during the business disruption caused by the pandemic.
Below are UC Cooperative Extension advisors and specialists who are available for comment:
Daniel Macon, UC Cooperative Extension livestock and natural resources advisor serving Placer, Nevada, Sutter and Yuba counties, dmacon@ucanr.edu
“Including all sheep will be HUGE for California producers. Most California lambs are born in the fall and marketed in the late spring. The rest of the West has lambs born in the spring and marketed in the fall/winter/early spring. The original CFAP payments provided a maximum payout to lambs that would have been marketed earlier than most California lambs. And provided no payment for what we call running-age ewes (breeding animals).”
Jackson Gross, UC Cooperative Extension aquaculture specialist at UC Davis, jagross@ucdavis.edu
“This is a big distinction for our California freshwater fish producers. While it doesn't cover all of the diversity in California aquaculture, it does cover the majority of our industry as far as freshwater fish producers. A specialty crop distinction is important for our fish farmers, making them eligible for specialty crop funding and numerous other federal and state programs that were previously inaccessible.”
Cheryl Wilen, director of UC Cooperative Extension in San Diego County, cawilen@ucanr.edu
“It is my impression that ornamental nurseries will really have a good opportunity to recover money for unsold crops.”
Ruth Dahlquist-Willard, UC Cooperative Extension small farms and specialty crops farm advisor for Fresno and Tulare counties, rdwillard@ucanr.edu
"The addition of crops such as bok choy, daikon, winter melon, and turmeric expands the program to include more of the specialty produce grown on small-scale Southeast Asian farms in the Central Valley. However, highly diversified farms may find it difficult to apply for small acreages of multiple crops, and with USDA offices operating remotely, additional technical assistance is needed to support farmers with the application process."
Ramiro Lobo, UC Cooperative Extension small farms and agricultural economics advisor in San Diego County, relobo@ucanr.edu
“The specific mention of minor crops can be significant for small-scale growers in the state, and Southern California in particular for growers of crops like dragon fruit, and other minor subtropicals because it legitimizes them as commercial crops.”
Aparna Gazula, UC Cooperative Extension small farms and specialty crops farm advisor for Santa Clara, San Benito, and Santa Cruz counties, agazula@ucanr.edu
“It's great that the USDA Coronavirus Food Assistance Program has been expanded to include more minor crops. I hope the USDA offices have bilingual staff who can work with socially disadvantaged farmers with language barriers that often grow these crops.”
Aliasghar Montazar, UC Cooperative Extension irrigation and water management advisor in Imperial and Riverside counties, amontazar@ucanr.edu
“Maintaining date palms over the season is very labor oriented. During February to May, a lot of activities need to be conducted at a certain time. As you know, we had high pressure from the pandemic in the Coachella Valley during these months. It made labor less available, which created some challenges for growers.”
Mae Culumber, UC Cooperative Extension nut crop advisor in Fresno County, cmculumber@ucanr.edu
“Almonds, pistachios and walnuts commodities all suffered a price decline between mid-January and mid-April as a result of the COVID-19 pandemic. Thirty to 50 percent of the previous season's crop is normally marketed during this time of the year. The CFAP program will provide financial relief for losses due to price decline and spoiled shipments that lost a marketing channel due to the pandemic. Commodity boards are working with the Farm Service Agency to assist producers in applying for the program.”
