American Pistachio Growers (APG) has been awarded a $5 million grant from the California Department of Food and Agriculture (CDFA) to help growers adopt healthy soils practices in the Golden State. The grant is a part of the California Healthy Soils Initiative, a collaboration of state agencies and departments that promotes the development of healthy soils on California’s farmlands and ranchlands.
The grant to APG is among 14 grants funded through the CDFA Healthy Soils Block Grant Pilot Program, which awarded $62 million in soils block grants in 2023 to various organizations. The program will fund projects for three years, with a limit of $200,000 per project over the lifetime of the grant. The objective is to better connect farmers and ranchers with programs that encourage and incentivize the implementation of management practices that sequester carbon, reduce atmospheric greenhouse gases, and improve overall soil health.
“As the non-profit trade association for the pistachio industry, American Pistachio Growers is uniquely positioned to assist growers in implementing and managing various Healthy Soils Block Grant qualified projects,” said Wes Wilson, APG Director of Member Services and Communications. “We look forward to connecting growers with these valuable programs that will not only improve the overall health of our California soils, but have the potential to reduce greenhouse gas emissions and sequester carbon, all while increasing yields and reducing traditional inputs.”
The agreement with the CDFA Office of Environ mental Farming and Innovation (OEFI) was executed on December 5, 2023, with grower applications opening January 1, 2024. APG anticipates funding more than 30 projects, with special consideration given to growers who qualify as Socially Disadvantaged Farmers and Ranchers or have farms of 500 acres or less.
APG will conduct outreach and accept applications from growers in Kern, Tulare, Kings, Fresno, Madera and Merced counties. Under the program, qualifying practices include compost application, cover crop planting and management, mulching, hedgerow planting, nutrient management that results in a 15% or greater reduction in fertilizer application, residue and tillage management, and prescribed grazing.
“Our pistachio growers are true innovators and conservationists, and this grant will bring even greater awareness to the importance of healthy soils in our pistachio orchards,” added Wilson. “It’s a benefit not only for growers but also for all Californians.”
American Pistachio Growers is the non-profit trade association representing more than 865 growers and member processors in California, Arizona, New Mexico and Texas.
The California Association of Winegrape Growers (CAWG) is excited to announce the receipt of a $9,908 grant from the 2023 California License Plate (CalAgPlate) program, administered by the California Department of Food and Agriculture (CDFA). This grant aims to elevate agricultural education and leadership opportunities for both students and teachers throughout California.
The grant project, aptly named “Creating a Sustainable Future: Owl Box Construction for Hands-On Agricultural Learning,” will empower FFA students with a unique hands-on experience in constructing 200 owl boxes. These purpose-built boxes will be distributed to winegrape growers as part of CAWG’s upcoming 50th-anniversary celebration in November 2024. Beyond the celebratory aspect, the grant presents FFA students with a valuable opportunity to contribute to practical solutions for sustainable agriculture.
Through this engaging project, students will not only gain woodworking experience but will also delve into essential aspects of agriculture, including the role of biodiversity, pest management strategies, and the critical importance of preserving natural ecosystems. The educational components seamlessly align with FFA’s overarching mission to nurture and develop young agricultural leaders.
Natalie Collins, President of CAWG, shared her enthusiasm for the grant, stating, “This project is truly exciting for both CAWG and California’s FFA students. It introduces solutions that promote hands-on learning and contribute to environmental stewardship, cultivating collaboration between our association and the future stewards of our industry in FFA. It’s a win-win that propels us toward a greener and more resilient viticultural landscape.”
This project was one of only four applications selected for funding in 2023. The funding for the CalAgPlate program is derived from the sales of specialized license plates with an agricultural theme, through the California Department of Motor Vehicles. Since the initiation of the CalAgPlate grant program, CDFA has awarded more than $2 million to foster agricultural education and leadership development.
The California Department of Food and Agriculture (CDFA) has declared a quarantine in Ventura County following the detection of the citrus disease Huanglongbing (HLB), or citrus greening, in two citrus trees on one residential property in the city of Santa Paula. These detections are the first HLB-positive trees in Ventura County. CDFA is working with the United States Department of Agriculture and the Ventura County Agricultural Commissioner on this cooperative project.
CDFA crews will be working to remove and dispose of the infected trees and are conducting a mandatory survey of every property within 250 meters of the detection site. After the survey is complete, all host plants in the 250-meter area around the detection site will be treated to suppress the disease vector, the ACP. By taking these steps, a critical reservoir of the disease and its vectors will be removed, which is essential to protect the surrounding citrus from this deadly disease.
These detections establish a mandatory five-mile citrus HLB quarantine area around the find site. The quarantine area is bordered on the north by Ojai Road; on the south by E Los Angeles Avenue; on the west by Wells Road; and on the east by Balcom Canyon Road. The quarantine prohibits the sale of all host nursery stock and the movement of all host plants or plant parts within a five-mile radius of the finds. The quarantine applies to residents and commercial operations alike. These detections will also place parts of Ventura County into Bulk Citrus Regional Quarantine Zone 6, which will require any commercial citrus growers to apply an additional mitigation step(s) to move fruit within or from this zone. Production and retail nurseries within the five-mile quarantine are being contacted by CDFA and will be issued a hold notice preventing the sale of nursery stock host plants. Visit CDFA’s Map and Quarantines page for more details.
Growers in Ventura County should contact Grower Liaisons Sandra Zwaal at szwaal2@gmail.com or Cressida Silvers at cressidasb@gmail.com for additional information about these detections. In response to the HLB detections in Santa Paula, a grower meeting was held on Wednesday, Oct. 4. Stay tuned to Citrus Insider for details or reach out to the Grower Liaisons for more information.
An HLB quarantine area currently exists in parts of Los Angeles, Orange, Riverside, San Bernardino and San Diego counties, where more than 6,300 residential trees have tested positive for the disease and have been removed. — California Citrus Pest & Disease Prevention Program
A Hmong small-scale farmer in Merced County has saved about 14.4 acre-inches of water annually and reduced greenhouse gas emissions by 12.406 MTCO2e per year (equivalent to the greenhouse gas emissions produced from burning 1,396 gallons of gasoline) after upgrading her farm. Rosie Lee – who sells Asian greens, green beans, corn, strawberries and other produce at her farm stand and to Asian markets – is one of hundreds of growers benefiting from California Department of Food and Agriculture incentives and funds with the assistance of Climate Smart Agriculture community education specialists.
“She is one grower who would not have access to those funds without my bringing my computer out to the field,” said Caddie Bergren, a Climate Smart Agriculture community education specialist who has been working with growers in Merced County since the program’s launch.
To make it easier for farmers to adopt new practices, CDFA and UC Agriculture and Natural Resources partnered to create the Climate Smart Agriculture program.
Drip irrigation has saved Lee about 14.4 acre-inches of water annually.
“Since 2019, UC ANR’s Climate Smart Agriculture Team has provided in-depth technical assistance to more than 1,300 farmers and ranchers in 24 counties,” said Hope Zabronsky, academic coordinator for UC ANR’s Climate Smart Agriculture team. “Through their strong relationships with diverse farming communities, they support the implementation of soil health, water efficiency, and manure management practices that optimize climate benefits for all growers and Californians.”
The program’s community educators work with farmers and ranchers in 24 California counties to get CDFA-funded grants and implement Climate Smart Agriculture projects. These efforts, which emphasize outreach to underserved farmers and ranchers, have resulted in a total of $36.5 million invested from the State Water Efficiency and Enhancement Program or SWEEP, the Healthy Soils Program, and the Alternative Manure Management Program.
“Agriculture is an important part of the climate solution,” said CDFA Secretary Karen Ross. “This funding enables CDFA and UC ANR to partner with farmers and ranchers to scale up climate-smart agricultural practices. This is essential as we contend with our hotter, drier future.”
Lee, the Hmong grower, had been growing 18 acres of vegetables by flood irrigating with groundwater. To save water and reduce pumping costs, she asked Bergren to help her apply for SWEEP funds to convert to drip irrigation and install solar panels. Bergren brought her laptop to the field to help Lee pull together the necessary information for the application. After Lee received funds for the project, Bergren assisted her with the technical logistics of installing the irrigation and solar equipment.
“I called vendors and we were able to complete the project on time,” Bergren said.
Through the Climate Smart Agriculture program, Lee, shown holding a soil moisture sensor, received help to apply for grants and complete the energy and water-saving project.
CDFA and UC ANR have published an impact report highlighting the results of the multi-year partnership focused on increasing adoption of climate-smart agriculture practices to reduce water and energy use.
The investments have funded more than 420 projects, so far. The projects are expected to save an estimated 8.3 billion gallons of water during their lifetime, enough to supply over 75,000 typical homes in California with water for a year. Additionally, there are projected reductions of more than 355,000 metric tons of carbon dioxide-equivalent, as much as would be achieved by removing 79,110 gas-powered vehicles from roads.
The report highlights the importance of providing tailored outreach, education and technical assistance to small-scale, non-English speaking, and otherwise underserved farmers and ranchers. — By Pam Kan-Rice and Josh Staab

The USDA National Agricultural Statistics Service’s (NASS) official walnut industry crop estimate provides the California walnut industry with crucial information to support an orderly sales process. Using scientific methodologies, USDA field staff counted, measured, weighed and evaluated thousands of walnuts from major growing regions in July and August for use in a statistical acreage model to establish the annual walnut crop estimate.
The 2023 California walnut production is forecast at 790,000 tons, up 5% from 2022’s production of 752,000 tons. The forecast is based on 385,000 bearing acres, down 4% from 2022’s estimated bearing acreage of 400,000.
“The California walnut industry has increased its focus on providing handlers and growers the most accurate crop information by accelerating the collection of various data points,” said Robert Verloop, CEO and Executive Director for the California Walnut Commission (CWC) and Board (CWB).
While official final shipment, inventory and close-out figures for the 2022 crop year will be released within the month, preliminary figures indicate last year’s crop is virtually sold out.
“Last year, we were facing a completely different scenario with 130,000 tons in inventory brought on by the lingering effects of the COVID-impacted global marketplace and a record heat wave last September that negatively impacted the entire crop, which led to lethargic sales and record-low grower returns,” added Verloop.
“With minimal carryover from the previous crop year and favorable weather throughout the growing season, we’re optimistic about the new crop year,” said Tim Sabado, CEO of Prima Noce, based in Linden, California. “The upcoming crop promises a return to the exceptional quality that defines California walnuts globally.
“Harvest will begin in September, and may extend into November due to the early season cooler temperatures,” added Sabado. “Our focus is on an aggressive harvest, picking the crop at its peak quality and freshness.”
Inshell walnut shipments for international destinations will start in October. In the U.S. and Canada, retail customers are currently placing orders and building sales plans for their traditionally large holiday promotions and their health-focused kernel campaigns for January and February.

What a difference a year makes! The California walnut industry is gearing up for a stellar 2023 harvest and shipping season after several years of drought, record low grower returns, COVID disrupted markets with supply chain challenges and a devastating heat wave in September 2022 that negatively impacted the entire crop. Here’s why this season is lining up to be a different story.
Quality is expected to be excellent due to favorable growing conditions.
Last winter’s prolonged heavy rains in the California walnut growing regions helped restore deep soil moisture and provided for healthy root zones, enabling trees to better tolerate late season high temperatures. The state also benefitted from an extensive snowpack which has provided all growing regions with sufficient water to support the trees and the crops through this season.
The much-needed chilling hours were at normal levels, placing the trees into a much-needed deep winter dormancy and a prolonged “rest and recuperation” period. Mild spring temperatures were ideal and produced full, vibrant, vigorous tree canopies which supported strong pollination, resulting in robust nut sets throughout the orchards.
“This year, our trees are more capable of handling higher temperatures than the previous years when the trees were under stress due to long-term deficit irrigation,” commented fourth-generation grower and handler Bill Carriere of Glenn, California. “Long-time growers have commented that the trees have not looked this strong and healthy in at least six to seven years. The full leaf canopy provided excellent temperature control and sun protection during the spring and summer months, allowing the walnuts to grow evenly with minimal sunburn. I am very optimistic that this year will mark a return to the premium quality walnuts we are known for in California.”
Acreage adjustments
Record low prices, brought on by an oversupply of darker than normal walnut kernels and weak demand in international markets, have taken a toll on growers, some opting to remove orchards from production. “Our family decided to pull out a productive orchard planted by my father in the early 2000s, it was a difficult decision, but the numbers told the story,” said Don Barton, a fourth-generation family farmer in Escalon, California. “We pulled a few acres with legacy varieties that are no longer desired by the broader buying community. Further south, walnut growers had removed trees due to new water restrictions that resulted in a lack of long-term availability to groundwater. Overall, the last few years have been devastating for growers and we are making some difficult decisions.”
The extent of the acreage shift became more evident in an acreage survey conducted by the California Walnut Board between October 1, 2022, and June 30, 2023. For the first time ever, the acreage of California walnuts declined with 23,000 acres removed during the nine-month period. The industry will likely see additional reductions between July and December 2023, as more growers decide to shift to other crops and the needed tree removal equipment becomes available.
Favorable New Crop Volumes and Inventory levels
However, even with the removal of these orchards, the industry has a strong production base with approximately 380,000 producing acres and 37,000 younger non-bearing acres. USDA/National Agricultural Statistics Service Information (NASS) is currently conducting the annual walnut crop objective evaluation which counts and measures walnuts in a representative cross-industry sampling protocol. Incorporating the recently updated acreage report with the sampling results. USDA will release the official California walnut industry crop estimate on September 1, 2023.
“This week, the California Walnut Board released the monthly and year-to-date shipment report which highlighted an additional reason why I am bullish about the upcoming season,” remarked Martin Mariani, a grower/processor from Winters, California, “The data shows that we have shipped the equivalent of 730,488 tons this season from an available inventory of 880,000 tons.” He went on to explain that when taking into consideration the high sales commitments going into the fall, “we are virtually sold out of available inventory, which bodes well for the industry. I can’t wait to bring the new crop to market.”
Global and Domestic Market Outlook
With a focus on inshell markets, Chile is anticipated to be sold out by the time the new California crop starts shipping this fall. With minimal inventories of export-quality walnuts on hand, coupled with the current limited supply of walnut halves in global markets, the fresh California crop of premium quality walnuts, inshell and kernels, will be in high demand.
“Domestically, sales have increased 28% which helped our industry work through the high inventory numbers we saw at the start of the season” said Mike Poindexter of Poindexter Nut Company in Selma, California. “Major US retailers significantly increased their promotional efforts, which stimulated consumer sales. This is continuing through the fall and will provide nice momentum going into the U.S. holiday season for new crop kernels and inshell sales.”
Market Development and Sales Expansion
Acknowledging the difficulty California walnut industry growers have faced in recent years, Robert Verloop, CEO and Executive Director for the California Walnut Commission (CWC) and Board, said the organization has taken several steps to aid growers.

“There have been successful efforts during the season to respond to the heat wave impacted crop, yet with low prices and high input costs, the squeeze on family farms has been relentless. Through the Commission, we continue to work with our representatives in Washington, D.C. and Sacramento for emergency relief for growers,” he said.
“Also, working with the CWC Board of Directors, industry handlers/processors, many volunteer leaders and elected officials and regulators, we have successfully secured a record USDA Section 32 purchase this season for up to $90 million; this funding is being used to help move the current crop out of our storage and into 1,400 food banks across the U.S., providing additional nutrition to thousands of families. In addition, the 20% reduction in tariffs recently announced by India will help us regain our footing in the Indian market.”
