Organic farming continues to expand in California and now includes more than 360 commodities, according to a new University of California report. The number of organic growers, acreage and farm gate sales revenue is reported by commodity, county, region and statewide in the new “Statistical Review of California Organic Agriculture, 2013-2016.” The data are collected from farms that register as organic with the California Department of Food and Agriculture.
“This report highlights the incredible diversity and abundance of organic crops being grown across so many different geographic regions in the state, which reflects California's leading role in this production sector,” said Houston Wilson, director of the new UC Organic Agriculture Institute.
“Dairies continue to lead by value of organic production,” said Rachael Goodhue, UC Davis professor of agricultural and resource economics and coauthor of the report.
The number of organic growers in California jumped from 2,089 in 2013 to 3,108 in 2016. The top 10 organic commodities for sales value in 2016 were cow milk, strawberries, carrots, wine grapes, table grapes, sweet potatoes, almonds, raspberries, salad mix, and chicken eggs.
“This review is critical to understand the changes in the fast-growing organic agriculture sector in the state where more than 50% of the nation's organic vegetables and fruits are produced,” said Joji Muramoto, UC Cooperative Extension organic production specialist at UC Santa Cruz and coauthor of the report. “It provides statistics of all organic commodities produced across the state as well as at county level. This is the primary reference to learn about the size, diversity, and trends of organic agriculture in the state.”
In 2016, California organic sales were $3.1 billion with an average of $1 million in sales per farm, but revenue varied widely among farms. For example, San Diego County had the most organic growers (313) in 2016, but Kern County's 47 organic farmers earned the most in total organic sales: $381 million on 49,727 acres, excluding pasture and rangeland, according to Muramoto.
“The average gross income of organic farms increased 14-fold from 1994 to 2016, reaching $1 million in 2016,” Muramoto said. “However, 77% of growers received less than $500,000 per year and 22% of growers who made $500,000 or more per year received 94% of the total gross sales, showing the income concentration among organic growers in the state.”
The statistical review of California's organic agriculture had been published since 1998 by the late Karen Klonsky, UC Cooperative Extension specialist, and her team after statistics for organic agriculture became available in 1992 as a result of the California Organic Food Act.
The last report published by Klonsky, who passed away in 2018, covered 2009-2012. All previous organic agriculture statistics reports can be accessed at https://aic.ucdavis.edu/research1/organic.html.
“This report of organic data continues the series of studies initiated by Karen Klonsky many years ago. It contains vital summary information for industry and policymakers as well as researchers,” said Goodhue.
Since the data collection began in 1994, the number of organic growers in California has increased 2.8-fold to 3,109 and the farm-level sales 40-fold to $3.1 billion in 2016.
“Accurate annual data on California organic crop production, acreage and value is critical to understanding the scale and scope of this growing agricultural sector,” said Wilson. “As the UC Organic Agriculture Institute begins to develop research and extension programs, it is important that we have a reliable way to assess the extent and geography of organic production as well as track changes over time.”
Muramoto, who became the UC Cooperative Extension organic production specialist in 2019, collaborated with Goodhue, Daniel Sumner, director of the UC Agricultural Issues Center and UC Davis professor of agricultural and resource economics; and UC Davis graduate student Hanlin Wei to produce the latest statistical review of California's organic agriculture.
More recent years are not included because the data collected by CDFA changed in 2017 and again in 2019 so they are not comparable to the data in this report.

Farmers who want to learn organic production practices for California specialty crops can now get training at their convenience on their own computers. The organic farming training is designed by the University of California Sustainable Agriculture Research and Education Program, Organic Farming Research Foundation and California Polytechnic State University in San Luis Obispo.
“This course includes information from the latest scientific research conducted by our University of California colleagues across the state, and boils it down into practical information for beginning or transitioning organic farmers of fruit, nuts, vegetables and other specialty crops,” said Sonja Brodt, UC SAREP academic coordinator for agriculture and environment.
The training program contains six learning modules: soil health, weed management, irrigation and water management, insect and mite pest management, disease management, and business management and marketing.
“We were able to draw on the expertise of 22 technical advisors, the majority of them from UC Cooperative Extension, UC campuses and Cal Poly San Luis Obispo, to ensure the scientific accuracy of the information provided,” Brodt said.
The program provides a combination of written content, videos and do-it-yourself exercises that allow students to follow along at their own pace and test their grasp of the knowledge. Farmers may read or view any parts of the course they choose, in any sequence. No certificate or credit is given at completion.
“While it was developed for California specialty crop farmers, the content is based on foundational principles that are relevant to all organic farmers and our hope is that growers across the U.S. find it to be a useful resource,” said Lauren Snyder, OFRF education & research program manager.
The organic farming training is free. To obtain a link to the training, submit a request at https://ofrf.org/beginning-farmer-training-program.
Funding for this online training program was made possible by the U.S. Department of Agriculture's (USDA) Agricultural Marketing Service through grant AM170100XXXXG011. Its contents are solely the responsibility of the authors and do not necessarily represent the official views of the USDA.
“The goal of our study is to provide organic farmers with science-based strategies that effectively limit food-safety risks when using raw manure-based soil amendments,” said Alda Pires, UC Cooperative Extension urban agriculture and food safety specialist in the School of Veterinary Medicine at UC Davis.
To study the survival of pathogens in soil and soil health, UC scientists are recruiting California growers who use raw or untreated manure in organically grown crop fields.
Pires is leading the project in California with Michele Jay-Russell, a veterinary research microbiologist and manager at the Western Center for Food Safety at UC Davis.
The researchers will visit participating farms eight times over the 2017-2018 growing season.
“We will collect produce, water, soil and manure samples,” said Jay-Russell. “All of the samples will be tested for bacterial indicators such as nonpathogenic E. coli and pathogens. We will ask the farmers to complete a short survey. The study is voluntary and all locations and names will be kept confidential.”
Eligible California farms must be certified as organic by the National Organic Program or California Certified Organic Farmers and fertilize with raw manure or untreated manure from dairy cattle, horses or poultry. The farms can grow any of the following produce: lettuce, spinach, carrots, radishes, tomatoes or cucumbers.
This study is being conducted in other states by the University of Minnesota, University of Maine, USDA Agricultural Research Service's Beltsville Agricultural Center, USDA Economic Research Service's Resource and Rural Economics Division, Cornell University and The Organic Center. The project is funded by a U.S. Department of Agriculture Organic Research and Extension Initiative grant.
One of the events that attendees could sign up for was lunch with a scientist at The Ohio State University, located a few miles away from the conference venue. I chose Prof. Jeffrey LeJeune, an infectious disease microbiologist and epidemiologist, because a focus of his research is food safety, one of the topics included in the UC Global Food Initiative that UC President Janet Napolitano launched on July 1.
On the day of the luncheon, a Sunday, we were driven to The Ohio State University in buses the university provided. We assembled in the lobby of the Ohio Union (it was homecoming on campus and the Columbus marathon was in progress nearby), and were soon escorted to the tables of the scientists we had picked. The university kindly (and safely!) provided lunch.
At LeJeune's table, we introduced ourselves to one another. LeJeune began his presentation to his 15 guests by rebuffing the five-second rule. According to this rule, food dropped on the ground will not become contaminated with bacteria if it is picked up within five seconds of being dropped. LeJeune said it does not work. “Eating off the floor violates all food-borne illness prevention advice,” he warned.
Perhaps because we in his audience were all science writers, he proceeded to discuss communication challenges facing scientists. He said most of the emphasis in graduate training is on making discoveries, with hardly any attention paid to communicating these discoveries in lay language to benefit the general public. Other challenges he mentioned are the information explosion we are witnessing, resulting in deaf ears turned to many scientists' voices; and language barriers between scientists and journalists that hinder effective communication.
“The pasteurization of milk was a huge benefit to the health of the human population,” he said. “Most cheeses in the U.S. are pasteurized cheese products.”
We asked him many questions. He answered them all. He explained that the U.S. has the safest food supply. Despite this, pathogens can enter the food chain through live animals, he cautioned. Further, refrigeration could be inadequate. He said about 80 percent of food and vegetable contamination occurs post-farm. His tip for what to eat when traveling: “Avoid raw or unpeeled foods. It is best to choose what is fully cooked and hot.”
LeJeune noted there is no evidence to suggest that GM foods are problematic from a food safety perspective.
“There are some concerns for sure,” he said. “But these are largely economic or political. Nutrition-wise, GM foods can be beneficial. From a food safety and nutritional standpoint, I also see no significant differences between organic produce and non-organic or regular produce. There could be, however, some environmental impacts related to the different production systems.”
More questions followed. A discussion on E. coli bacteria gathered momentum, specifically how E. coli gets infected with a virus and how, when this virus decides to leave E. coli, it releases Shiga toxins, which, in turn, damage cells lining the kidney.
We were so engrossed in the discussion that it came as a surprise when one of the organizers of the luncheon strode into the room to inform us that our hour with the scientist was up and that the bus that had transported us to The Ohio State University was about to leave.
As we rose hastily from our chairs we thanked LeJeune for his presentation, which was clear and to the point – qualities all science (and other) writers appreciate. We know he had other topics to discuss with us: Can I cook my Jack-o'-Lantern after Halloween? (The answer is “Not if it sits out for more than two hours.”) And are raw diets for dogs a public health concern for humans? (The answer is “Your dog is more likely to have Salmonella if it is eating raw food.)
Although we didn't get to these topics, he left us with ample useful information about food safety. On the ride back to the conference, the bus was loud with conversation from the various lunch groups – what had been learned, how best it could be communicated, and how each one of us had made a new friend at the university.
At the same time, chefs and food buyers at universities, particularly the University of California, are selecting for high-quality fruits and vegetables, produced locally and sustainably. Universities with strong food sustainability programs are rightfully proud of what they're doing to educate students about food production, health, and nutrition. UC Davis Dining Services prioritizes the purchase of locally grown food (ideally within a 50-mile radius of campus). Most University of California campuses have similar programs.
At UC Davis, fresh roma tomatoes are picked each August from the 300-acre Russell Ranch, part of the campus's Agricultural Sustainability Institute, then processed within hours by campus Dining Services to provide year-round tomato sauce for pizza, pasta, and ratatouille. All told, 10,000 pounds of tomatoes are processed during a two-week period in August. About 29 percent of the total food served in the campus's residential dining halls is from local, organic or sustainable sources.
Emma Torbert, an academic coordinator at the UC Davis Agricultural Sustainability Institute, noted, “Connecting the food system to the research is really interesting. A lot of times there is confusion about where our food is coming from. The more people are educated, the more educated decisions they can make.”
Many UC Davis faculty and staff are so impressed with the food choices at the dorms that they purchase individual meal tickets and enjoy lunches made with the campus-grown tomatoes, herbs, and other vegetables, all of which are part of the daily food array. Public dinners are also offered periodically at the dorms so that community members can sit amongst students to taste and learn about the sustainability programs in the dorms.
