UC Cooperative Extension advisors, educators join growers in showcasing rice production
When Tracy Schohr volunteered in her son's pre-K class a couple years ago, she was stunned to find out that only two of the 20 children had ever been around a tractor. And this was in the rural Butte County community of Gridley, in the heart of California's rice-growing region.
Seeking to introduce more young children to agriculture, Schohr – the University of California Cooperative Extension livestock and natural resources advisor for the area – and her friend Lisa Donati created an event to showcase rice farming.
After the debut of “Ricetastic Day” last year with about 140 students from Gridley in attendance, this year's event on Sept. 19 attracted more than 240 schoolchildren – this time from across south Butte County.
First graders from McKinley Primary School in Gridley, Manzanita Elementary School, Biggs Elementary School and Richvale Elementary School – along with their teachers and many family members – enjoyed hands-on experiences at Schohr's rice and cattle ranch.
“There's a dwindling population that produces the food that we eat across America, so how can we have more people know, appreciate and love agriculture if we don't give them that opportunity?” said Schohr. “That's what this day is really about – to teach them about rice, to teach them about their community, how healthy rice can be, and how the farming and ranching can also be habitat for wildlife. It's all-encompassing.”
Event stations share different aspects of rice
Schohr, who grew up on the family ranch in Gridley, remembers coming with her McKinley schoolmates for a visit. But those field trips had comprised only lunch and a quick “drive-through” tour of the historic farming operation.
For Ricetastic Day, however, Schohr organized – with generous help from local growers and community partners – a more comprehensive half-day of activities. After her brother, Ryan Schohr, welcomed the participants to the family farm, the students formed groups that were led by Gridley FFA youth on a rotation through a variety of stations.
At the milling station, Luis Espino, UCCE rice farming systems advisor, demonstrated how his mini mill machines remove the husks from rough rice to make brown rice, and then polish away the bran layer to make white rice. He had the children see and feel the difference as the rice moved through processing.
“I didn't even know brown rice existed!” exclaimed Elsie, a first grader at McKinley.
A native of Peru, Espino came to study agriculture through his lifelong fascination with biology and living things – and he said events like Ricetastic Day can inspire a similar passion in young people.
“It might spark their curiosity so that they might go into these areas of work in the future or have a career in agriculture, when they see that people do this for a living,” Espino said.
Ray Stogsdill, another McKinley school alumnus, returned to Gridley after college to pursue just such a career. A staff research associate in the lab of UC Davis professor Bruce Linquist, Stogsdill manages on-farm rice variety testing across the region. He volunteered to help Schohr with Ricetastic Day by talking about some of the heavy equipment and providing his perspective for the kids.
“They drive by the fields and they don't know what's out there,” he said. “This gives them a chance to know what they're driving by, so they can say, ‘We have rice here and this is how it works; this is how it grows.' It gives them an idea of what's going on around them.”
Where rice fits within a healthy diet was the focus for the CalFresh Healthy Living, UC Cooperative Extension team, comprising nutrition educators Sunshine Hawjj, Joanna Aguilar and Kenia Estrada, as well as community nutrition, health and food security advisor Veronica VanCleave-Hunt. They talked about how rice – like other grains in that vital food group – gives people energy, and then taught the students an energetic “ricetastic” movement activity.
“Because our program is part of UC Agriculture and Natural Resources, it's important to make the connection between where our food comes from and how it gets on our plate – especially with young kids, so that we can promote value for our local agriculture and our food systems,” VanCleave-Hunt explained.
Activities spark further conversations, learning about agriculture
With rice harvest late due to late planting in the spring, Eric Waterbury of Waterbury Farms was able to take some time to attend the event. Although his family has been growing rice for three generations, he said he appreciates opportunities for the broader community to see all aspects of his work – from the equipment to the processing.
“If the kids walk away from this with one thing, I hope it's that they realize every time they have a meal, somebody was out there working hard to provide that meal,” he said. “It wasn't just the person at the grocery store that provided it for them.”
Schohr added that Ricetastic Day was only possible through the support of the community. Butte County Farm Bureau and Natural Resources Conservation Service staff helped kids make art with colorful dyed rice; neighboring farmer Tinker Storm described how the harvester and “bankout” wagon work; and rice farmers Shelley Beck and Sue Orme read aloud “Daddy's Got Dirt: A California Rice Story,” a children's book written by a local rice grower.
With rice at the center of physical activities, arts and crafts, and science lessons for the day, the students learned a lot to take home.
“It's nice that the kids got these hands-on learning experiences,” said Ryan Schohr, “so they can go home tonight and, at the dinner table, talk about it with their parents or brothers and sisters, over dinner or over homework – and share what they learned here on the farm and about their community.”
Rebecca Christy, a first- and second-grade teacher at Biggs Elementary, said she is excited to return to the classroom and hear from her students about all that they learned during the day.
“Every morning right now I'm seeing the big trucks going by our school, and so I'll be able to point that out to them, ‘Where are they going? What are they doing?'” she said. “I can't wait to get back to school and let them tell me about all of this.”
One of her students, Ximena, was finishing her brownbag lunch as the group watched one of the Schohr Ranch harvesters rumble over the field. Despite enjoying a rice cake and a rice cracker earlier, she said her meal was missing one thing.
“Where is my rice, Miss Christy?” she said. “I want rice!”

Growers, UC Cooperative Extension researchers offer guidance on producing high-quality olives
Facing a deluge of lower-price products from Europe, the California olive oil industry is doubling down on its clear-cut competitive edge: the consistent and bona fide quality of its oil.
“Olive Production Manual for Oil,” a new book published by University of California Agriculture and Natural Resources, aims to help California olive growers maximize that advantage.
“It's a tough market to compete in, but I think the way to win for California is to compete on quality,” said book co-editor Selina Wang, a UC Cooperative Extension specialist in the UC Davis Department of Food Science and Technology. “The quality of California olive oil is unmatched, but you can't make good quality olive oil with bad fruit, so the goal is to get more fruit from the trees – and for the fruits to be high-quality fruit.”
The 273-page manual, available for purchase online, is the first of its kind in the U.S. While some parts of the book are specific to California (which grows nearly all of the olives for domestically produced olive oil), most of the material would be useful to producers in other states, Wang noted.
“Through our conversations with growers, it became clear to us that a manual like this – not a scientific publication but a manual that is easy to follow, written in language that is accessible, and with pictures and illustrations – would be really helpful to the growers,” she said.
Growth of California olive oil industry necessitated creation of manual
Aside from a book focused predominantly on table olives and another on organic olive production (by UCCE farm advisor emeritus Paul Vossen), there was no one-stop, comprehensive resource on the bookshelf for oil olive growers. The need for such a manual had become more acute as oil olives replaced table olives in California orchards during the last 20 years.
Whereas harvesting by hand was historically cost-prohibitive, the introduction of super-high-density planting systems in 1999 made oil olive production more economically feasible. Mechanical pruning and harvesting of new cultivars (Arbequina, Arbosana and Koroneiki) – specifically bred for these densely planted orchards – led to the rapid expansion of oil olives in the state. According to a U.S. Department of Agriculture report, California olive oil production jumped from 2 million pounds in 2006 to an average of 21 million pounds in 2021–23.
With about 37,000 acres of oil olives planted across California, the Olive Oil Commission of California saw the need to support the production of this manual. Championed by Dan Flynn, founder and executive director emeritus of the UC Davis Olive Center, Wang and co-editor Louise Ferguson outlined the contents of the book. They then sought out a mix of growers and industry professionals and UCCE advisors and specialists to write its chapters.
“Most of the information is data-based, from people who are working with the olives,” said Ferguson, a UC Cooperative Extension pomologist at UC Davis. “This is the first data-based olive oil production manual we've had.”
Manual infused with firsthand insights, practical recommendations
Hard-earned experience taught growers a valuable lesson that is conveyed in the book – the need to hand-prune. While mechanical pruning helps control the size of the trees, some hand-pruning is still required to allow light to filter to the leaves. Failing to do so leads to a dramatic decrease in yield.
“That happened in many of the orchards that were inexperienced in these new cultivars and new super-high-density planting systems,” Ferguson said.
She added that other key topics in the manual include irrigation management in a water-constrained state, nitrogen management, harvest timing and orchard site selection. Choosing a good spot for planting is crucial in this era of extreme climate volatility, Ferguson noted, as olive trees are significantly affected by temperature shocks in spring (fruit set) and fall (harvest).
For Wang, another overarching theme in the manual is the importance of testing. Testing the soil, water and leaves provides critical data that growers can use to adjust their inputs and production practices for optimal profitability.
“You may spend a couple hundred dollars on the lab work, but it will pay off, for sure – you're going to increase the health and productivity of your trees,” Wang explained. “Oil olive growers are paid based on the oil content in their fruit; you not only want to have a lot of fruit on the trees, you want to make sure that your fruit are accumulating oil.”
California oil olive growers, practices continue to evolve
Wang and Ferguson hope their book will help California producers compete more effectively in the global marketplace. Currently, about 90% of the olive oil consumed in the U.S. is imported from Mediterranean countries, due primarily to the lower price point. In that region, producers tend to harvest riper olives that produce oil at a greater volume but lesser quality.
In contrast, California growers harvest earlier and produce oil that is higher quality (with more flavor and more antioxidants) and far exceeds accepted standards for “extra virgin olive oil.”
According to Wang, California olive oil mills have nearly maximized their efficiency, and the growth opportunity for the industry is in the orchards: to optimize practices to produce more fruit, and to plant more trees. Wang said the new manual can help on both fronts.
“Just like for other crops, focusing on quality – while increasing efficiency and productivity, and therefore profitability – is the name of the game,” she said.
Ferguson also stressed that knowledge continues to evolve and urged growers to reach out to the editors and chapter authors with their experiences.
“Most of the authors are in California and they're working,” she said. “So if you start to notice things that are different, or you want more information or something is not clear, the authors are available.”

Each year the California Avocado Commission partners with Land IQ to produce a Statewide Avocado Acreage and Condition Analysis report utilizing digital satellite imagery, aerial photography and analytical tools to survey California avocado groves. This data helps the Commission make informed budgeting and marketing decisions and provides industry members with spatial data concerning crop type, location, condition and density. See the full 2023 Report HERE.
According to the report:
- In 2023 there were 52,534 planted avocado acres
- The majority of growing acreage is located in Ventura, San Diego, Santa Barbara, Riverside and San Luis Obispo Counties with a total of 50,818 planted acres
- The five top-producing counties reported 1,059 new/young acres and 3,399 topped/stumped acres
The report also provides acreage data by zip code, county, condition, year planted and density.
The California Avocado Commission's crop estimating team in conjunction with Land IQ uses the latest in remote sensing techniques to assess avocado acreage in production. As technology continues to advance refinements in our fourth generation of remote sensing techniques were applied to satellite imagery collected during spring and summer months. The imagery processing techniques include; segmentation into homogenous polygons, retention of tree crop polygons, calculation of average crop canopy moisture and vegetation indices, analysis of change maps from previous inventories, and classification of avocado groves into four categories; producing, topped/stumped, new/young, and abandoned. Aerial imagery (for a real-world view), and satellite imagery (for spectral and temporal data) are integrated into previously classified avocado acreage and analyzed for current condition of California avocado acreage statewide.

Hello Small Farms Community! My name is Emily Kraus and I am excited to announce that I have joined the UCCE Small Farms team in Fresno. Back in June (2024), I made the treck to Fresno from Florida. I had a little time to settle in before beginning my new role here in July. Since then I have been BUSY trying to figure out how to serve the community of small farmers in the area. Please read on to learn a little more about me and my hopes for the program.
My Background
My journey began like many others, with one step out the door of my parents' home in Indiana. The first big stop was at Purdue University where I received my B.S. in Entomology, the study of insects! The projects I worked on there involved biological control of soybean aphid and genetic work on the human body louse. Both agricultural and medical entomology were interesting to me and I had a hard time deciding which to pursue. I ended up going to Kansas State University next where I completed my M.S. in entomology with a focus on mosquitoes. It turned out I didn't like being indoors all the time so I decided to join the U.S. Peace Corps as a Sustainable Agriculture Extension Agent. They sent me to Senegal West Africa! That was an amazing experience.
From there I decided to continue to pursue agriculture and worked briefly at Monsanto before going on to Louisiana State University. There I did my PhD work in rice production. I loved working on the universities rice farm and talking to rice growers at Extension meetings. Ultimately, I graduated and had to decide what to do next. I decided to do a postdoctoral fellowship at Rhodes University in South Africa. There I worked on biological control of invasive weeds. It was very interesting work. There are not many places where your field work might put you in a river with crocodiles and hippos!
When I came back to the U.S. I wanted to move to Florida to spend more time with my family. First, I worked at the Florida Department of Agriculture and Consumer Services (FDACS). This role also involved biological control of invasive pests. I learned about the Asian citrus psyllid and met a whole new group of farmers. After a few years I switched over to the University of Florida and spent two years in the Pesticide Information Office as an Extension Scientist. It was from this work that I learned all about becoming a certified pesticide applicator. The only problem was that there was no research opportunity in this position which is one of many reasons I wanted to become a Farm Advisor here in Fresno.
Getting Started in Fresno
It has taken me a couple of months to get going in this role. Many of you reading this know I am coming in after Ruth Dalquist-Willard. Due to her extensive success I have quite a large program to take over! I have been spending my time meeting the team and making connections with other organizations in the area. Also, I have made a point to get out on the farms. There is so much diversity in the small farms in this region and it seems it could take a lifetime to learn about them all.
As a team we intend to continue many of the projects that Ruth had going. These include investigating benefits of cover crops and compost, working with growers to pass food safety inspections, supporting growers with information on pesticide regulations, trouble-shooting various issues with water access and quality, and tracking the expansion of new pests like the Mexican Rice Borer. There is no shortage of things to do! As I learn more about the specialty crops and challenges our stakeholders face, I am designing new projects and will be keeping the team busy!
Looking Forward to Meeting You!
The most important part of getting started in this role is for me to meet our partners and stakeholders. Please reach out and introduce yourself! I will certainly be making the rounds to local farms and networking events, but don't hesitate to put yourself on my radar. The team here in Fresno is excited to continue to serve our stakeholders as I transition into this role. We want to hear about your concerns and figure out how we can continue to support small farms in Fresno and Madera counties, as well as contribute to projects across the state. I'm looking forward to meeting you!
