UC study breaks down costs of growing organic strawberries
Thinking about commercially growing organic strawberries on the Central Coast?
To help prospective and current growers evaluate financial feasibility, the University of California has estimated costs to produce and harvest organic strawberries for fresh market in Santa Cruz, San Benito and Monterey counties.
“This revise of the last cost-of-production study incorporates the newest in labor costs along with updates on cultural techniques,” said study co-author Mark Bolda, UC Cooperative Extension strawberries and caneberries advisor in Santa Cruz, San Benito and Monterey counties.
The new study, “Sample Costs to Produce and Harvest Organic Strawberries in the Central Coast Region-2022,” has been released by UC Agriculture and Natural Resources and UC Davis Department of Agricultural and Resource Economics.
The analysis is based on a hypothetical well-managed organic strawberry farm using practices common to the region, but the costs, materials and practices shown in this study will not apply to all farms. Growers, UC Cooperative Extension farm advisors and specialists, pest control advisers and others provided input and reviewed the methods and findings of the study.
“Current growers can use it as a baseline to compare with their own cost and returns estimates to make sure they have an accurate picture of the profitability of their organic strawberry enterprise,” said co-author Brittney Goodrich, UC Cooperative Extension agricultural economics specialist. “Many agricultural lenders use these studies as a baseline to determine whether to approve operating or investment loan requests from current and potential strawberry growers.”
The researchers assume a farm operation size of 30 contiguous acres of rented land, with strawberries are planted on 27 acres. The study includes a list of suitable strawberry varieties for the region, but no specific variety is used in the study. The crop is harvested by hand and packed into trays containing eight 1-pound clamshells from April through early October, with peak harvest in June through August.
The authors describe the assumptions used to identify current costs for production material inputs and cash and non-cash overhead. Ranging analysis tables show net profits over a range of prices and yields. Other tables show the monthly cash costs, the costs and returns per acre, hourly equipment costs, and the whole farm annual equipment, investment and business overhead costs.
The study's expanded section on labor includes information on California's new minimum wage and overtime laws.
“It's reached a wider audience this time through presentations of the material to students at Cal Poly [San Luis Obispo] and also a group of USDA officials at the California Strawberry Commission,” said Bolda.
“All of this just underlines the value of these studies to California growers and others working in agriculture,” Bolda said.

COVID-19 not a current threat to the food system, but California farmers still feel the pinch
COVID-19 does not currently pose major threats to overall global food security because adequate stores of staples — like wheat and rice — remain available. But the sustainability of California specialty crops may face greater hurdles, reported Laura Poppick in Scientific American.
Poppick spoke with two UC Agriculture and Natural Resources (UC ANR) scientists for perspective on the future of California agriculture considering the market and production constraints posed by measures to slow the spread of the coronavirus.
“Everybody is scrambling to figure out what to do,” said Gail Feenstra, deputy director of UC ANR's Sustainable Agriculture Research and Education Program. “There's just a lot of disruption.”
Specialty products — such as some fruits and organic produce grown on smaller-scale farms — are often sold to restaurants and farmers markets, many of which are now closed or have reduced service, rather than directly to the grocery stores that are still operating. Even if these farmers are able to continue working, they may have limited places to sell their goods, the article said.
Strawberries are another crop likely to be affected. Laborers picking strawberries typically work more closely than is advisable to prevent the spread of the virus, said Mark Bolda, a University of California Cooperative Extension farm advisor based in Watsonville. He said farmers are already making plans to spread workers between rows.
Strawberries, however, hit prime ripeness within a narrow window of just two to three days and must be picked quickly, Bolda says. Spacing workers may slow picking, and, "being slower is expensive."
Thinking about growing romaine or organic strawberries? UC ANR releases sample costs
Farmers who are considering growing romaine hearts or organic strawberries in California's Central Coast region can get some help determining whether the crop will pencil out for them.
UC ANR Agricultural Issues Center and UC Cooperative Extension have released sample costs to produce and harvest organic strawberries for fresh market and romaine lettuce hearts in Santa Cruz and Monterey counties.
A major difference between growing strawberries organically and the conventional practice is in weed control.
“Weed management is especially challenging for organic strawberry production because soil fumigation and most herbicides are not allowed under organic regulations,” said Mark Bolda, UC Cooperative Extension farm advisor in Santa Cruz County. “Weeds in furrows between the beds can be mechanically cultivated during the growing season, but most of the weeding will need to be done by hand from December through September.”
The cost analyses are based on hypothetical well-managed farming operations using practices common to the Central Coast region. The costs, materials and practices shown in the studies will not apply to all farms and are intended to assist growers in estimating their own costs.
The organic strawberry study assumes a farm with conventionally grown strawberry transplants planted on 27 contiguous acres of rented land. “Organic strawberry transplants are part of the picture now, but not standard by a long shot,” said Bolda, who co-authored the cost studies. The strawberry crop is harvested by hand and packed into trays containing eight 1-pound clamshells, from April through early October with peak harvest in June and July.
For romaine lettuce for the hearts market, the cost study assumes a farm of 1,500 non-contiguous acres of rented land, with romaine planted on 250 acres and rotated with other lettuce and cool season vegetable crops to assist with pest management and soil fertility. Lettuce is planted continuously from late December to mid-August along the Central Coast. To manage lettuce mosaic virus, Monterey County has a host-free period (December 7 – 21), during which time lettuce may not be planted. In this study, lettuce is planted in January.
For both the organic strawberries and romaine, ranging analysis tables show net profits over a range of prices and yields. Other tables show the monthly cash costs, the costs and returns per acre, hourly equipment costs, and the whole farm annual equipment, investment and business overhead costs. The authors describe the assumptions they used to identify current costs for production material inputs and overhead.
The authors have also expanded the section on labor, which includes information on California's minimum wage and overtime laws.
Growers, UC ANR Cooperative Extension farm advisors and other agricultural associates provided input and reviewed the methods and findings of both studies.

First-ever UC cost study for primocane-bearing blackberries released
The first-ever cost study of primocane-bearing blackberries in California has been published by UC ANR's Agricultural Issues Center and UC Cooperative Extension. With primocane-bearing, growers can extend the blackberry production season.
“What differentiates primocane-bearing blackberry from the traditional floricane-bearing is that it bears fruit in the first year rather than the second,” explained co-author Mark Bolda, UC Cooperative Extension advisor.
“Which, of course, opens a world of opportunity for growers, since they are able to produce fruit in the first year rather than the second as has traditionally been the case,” Bolda said. “That's what makes this study so interesting to us.”
Primocanes are the green, vegetative stalks of the blackberry plant, generally the first-year cane. The second year, they become floricanes, flowering and fruiting.
The study presents sample costs to establish, produce and harvest primocane-bearing blackberries in the Central Coast Region of Santa Cruz, Monterey and San Benito counties.
The analysis is based on a hypothetical well-managed farming operation using practices common to the region. The costs, materials and practices shown in this study will not apply to all farms. Growers, UC ANR Cooperative Extension farm advisors and other agricultural associates provided input and reviewed the methods and findings of the study.
This study assumes a farm operation size of 30 contiguous acres of rented land, with primocane-bearing blackberries for fresh market planted on 15 acres. The crop is hand-harvested and packed into 4.5 pound trays. During the establishment year, there is a four-month harvest – July through August. Primocane blackberries can produce fruit on first-year growth. There is also a four-month harvest for each of the four production years.
The authors describe assumptions in detail and present a table of costs and returns based on those assumptions about production, input materials, prices and yields. A ranging analysis shows the impact on net returns of alternative yields and prices. Other tables show the monthly cash costs, the costs and returns per acre, hourly equipment costs, and the whole farm annual equipment, investment and business overhead costs.
The study also has an expanded section on labor, which includes information on California's new minimum wage and overtime laws.
“This work investigating the economics of a newer cultural system for our area came out of a close collaboration between UCCE academics and area growers,” said Bolda, who serves Santa Cruz, Monterey and San Benito counties, “so the level of detail and accuracy is outstanding.”

Agtech is changing farming in California
Technology holds tremendous promise for the California agricultural industry, however there are challenges that must be better understood and managed, wrote Damon Kitney in an article distributed to participants in an Oct. 2 technology conference in San Francisco.
Using artificial intelligence to speed up genetic selection is one area where technology is evolving in the laboratories of the Silicon Valley. Glenda Humiston, the vice president for UC Agriculture and Natural Resources, was quoted extensively in Kitney's article about the potential of AI and other technologies in agriculture.
"Artificial intelligence is extremely difficult in agriculture because of the huge amount of variability in environmental conditions across a single field," Humiston said. "This requires many sensors, complex algorithms and large real-time data processing - all integrated and working together to inform decisions and actions."
Humiston said the ability to pull together an array of data - from drones, robots, sensors and genomics - and use it for informed decision making will require significant improvements in how 'big data' is managed. Point solutions are being developed by universities, startups and corporate innovators, but few are integrated to provide real-life solutions for farmers.
"Integration will be a key factor in making these technologies affordable and available to most farmers," she said. "Many startup technologies for agtech are hitting the market with glossy websites, pitch events and marketing materials that appeal to investors, but the science behind them is dubious."
A key issue covered in the article is the cost and availability of labor in berry production. About 60 percent of the costs associated with berries are labor. At times, a significant portion of berries are lost when farmers can't find labor to get them picked.
Despite the effort to find technology to cut labor needs, human labor in the field will never be replaced, according to Mark Bolda, UC Cooperative Extension strawberry and caneberry advisor for Santa Cruz County.
"It's not realistic to see robots as the full solution for our labor issues, rather more success will be found in berries by combining robots with already existing labor of humans," he said.
Berries are very soft fruits. Technology to find them, pick them and put them in a box does not exist, Bolda said. Robots of the future will likely transport full boxes out of the field, bring in new boxes, monitor the rate of picking and charting field issues.
UCCE farm management advisor Laura Torte concurs.
"Humans bring sensory attributes to agriculture that robotics and mechanization has not - yet - been able to perfect," she said.
