Safe, healthy and happy Thanksgiving
UC Agricultural Issues Center has released new studies estimating the cost and returns of establishing an almond orchard and producing almonds for three growing regions of California.
“These cost studies are valuable for agricultural producers all along the continuum – growers considering entering into a new crop production business, less experienced growers, and those with decades of experience,” said Emily Symmes, UC Cooperative Extension integrated pest management advisor for the Sacramento Valley. “The information in these cost studies allows growers to evaluate their production practices and associated costs relative to an exemplary hypothetical orchard specific to their geographic region, and can help with development of business models, crop insurance and lending.”
In 2018, almonds ranked third among California commodities with almond growers receiving nearly $5.5 billion in cash receipts.
The cost analyses are based on hypothetical farming operations of well-managed almond orchards, using cultural practices common to the region. Local growers, UC Cooperative Extension farm advisors and supporting agricultural representatives provided input and reviewed the methods and findings of the studies.
“The recent almond updates for the Sacramento and San Joaquin valleys reflect costs associated with the continually evolving conditions facing agriculture,” said Symmes, who co-authored the almond cost studies. “Some of the notable updates include labor, irrigation and pest management costs – all integral to producing and delivering a high-quality crop.”
The researchers based one study in the Sacramento Valley, one in the northern San Joaquin Valley and the other in the southern San Joaquin Valley.
The southern SJV study is based on an orchard that uses double-line drip irrigation, whereas the other two locations use microsprinkler irrigation. All are multi-year studies, estimating costs from removal of the previous orchard, through almond orchard re-establishment and the production years. The economic life of the orchards used in these analyses is 23 to 25 years.
Navel orangeworm (NOW) is a major pest in almond production; Symmes and her co-authors describe in detail the pesticide applications and winter sanitation methods for each location for NOW control and include the costs.
The authors describe the assumptions used to identify current costs for orchard establishment, almond production, material inputs, cash and non-cash overhead. A ranging analysis table shows net returns over a range of prices and yields.
The new studies are titled:
- Sample Costs to Establish an Orchard and Produce Almonds in the Sacramento Valley - 2019
- Sample Costs to Establish an Orchard and Produce Almonds in the Northern San Joaquin Valley - 2019
- Sample Costs to Establish an Orchard and Produce Almonds in the Southern San Joaquin Valley - 2019
The studies are available for free download at the UC Davis Department of Agricultural and Resource Economics website at http://coststudies.ucdavis.edu. Sample cost of production studies for many other commodities are also available on the website.

Scientists are developing climate-smart farming practices, California is offering financial incentives to implement them, and now a group of 10 UC Cooperative Extension climate-smart educators are taking the program to the next level.
To help farmers apply for grants to improve soil quality and enhance irrigation systems, UC Agriculture and Natural Resources partnered with the California Department of Food and Agriculture to put climate smart educators in 10 California communities. The educators are working closely with UCCE advisors to help farmers and ranchers improve soil health, irrigation practices and manure management.
The climate smart programs offered by CDFA and promoted by UC ANR educators are:
- State Water Efficiency and Enhancement Program
- Healthy Soils Program
- Alternative Manure Management Program
The educators provide hands-on assistance to farmers and ranchers through the complex application process, conduct field days with climate-smart farmers, establish demonstration plots to share the practices, and work with farmers who are voluntarily implementing climate-smart farming.
Most of the educators were hired in early 2019, just weeks before the application deadline. They are now gearing up for a second cycle of applications. The state funded 194 projects in 2018, and 217 in 2019.
Each of the educators has a passion for agriculture and the environment, shaped by their upbringing, experiences and education.
“I am interested in carrying out research that focuses on the adoption and economics of climate change best management practices. The practices should help farmers continue their business,” said Esther Mosase, climate-smart educator in San Diego County. “I'm interested in seeing policymakers making policies that have a farmer as a focal point. They have been here long, they have been tilling the land, they can also contribute in coming up with better solutions that reduce climate change.”
The state is providing incentives for farmers to improve soil health in order to moderate the conditions that are driving global climate change. Improving soil health increases its ability to store carbon and reduce greenhouse gas emissions. Side benefits include improved water infiltration, nutrient cycling and dust control.
Farmers can apply for three-year grants to implement new practices on their farm, such as reducing tillage, growing cover crops and applying compost. Conventional farm practices turn the earth, releasing the stored carbon back into the atmosphere.

Mosase has a master's degree in agricultural engineering from Botswana College of Agriculture and a doctorate from South Dakota State University in civil engineering. Her master's research focused on water resources, watershed modeling and management.
Raised in a farming family in Botswana, Mosase experienced the impact of climate change firsthand.
“I remember we had drought years, normal years and extremely wet years,” she said. “Twenty years ago, it was not uncommon for open water to freeze. But now we get mild winters and very hot summers. Rain-fed agriculture is now a risky enterprise compared to two decades ago.”
In addition to helping farmers with the climate-smart farming grant applications, Mosase is helping farmers cope with water quality concerns.
“For instance, one farmer wanted to improve the water quality at the edge of his avocado and citrus farm before it enters the stream. He also wanted to be helped with pools of standing water in the farm that usually affect the health of avocado trees,” Mosase said. “We advised him on what to do regarding the standing water, but for the edge of the field treatment, we decided to install bioreactors.”
Mosase will help collect field data on the bioreactors' effectiveness and plans to publish the results.

Some people believe shouting, waving arms and flashing lights will keep coyotes at bay, but UC Cooperative Extenison wildlife-human interaction advisor Niamh Quinn isn't so sure, reported Louis Sahagun in the Los Angeles Times. Like any scientist, she is now conducting a research project to understand whether such hazing deters the wild animals from making their homes in urban areas.
"There is no scientific evidence that hazing alters the behavior of urban coyotes," Quinn said."Yet, it is being pitched as a good option for coyote management."
Quinn is trapping coyotes, sedating them, attaching radio collars, tagging their ears and tracking their movements to understand whether the techniques recommended by some cities and animal rights groups are effective.
“We want to figure out when, where and for how long it actually works, or if it even works at all,” she said. “For the sake of our communities, and coyotes, too.”

Scorching temperatures and parched earth are no match for the sorghum plant — this cereal crop, native to Africa, will remain green and productive, even under conditions that would render other plants brown, brittle and barren.
A new study published this week in the journal Proceedings of the National Academy of Sciences provides the first detailed look at how the plant exercises exquisite control over its genome — switching some genes on and some genes off at the first sign of water scarcity, and again when water returns — to survive when its surroundings turn harsh and arid.
“With this research, we are laying the groundwork for understanding drought tolerance in cereal crops,” said Jeff Dahlberg, UC Cooperative Extension sorghum specialist. Dahlberg, co-author of the study, is also director the UC Kearney Agricultural Research and Extension Center in Parlier, one of nine research and extension centers in California that are part of UC Agriculture and Natural Resources.
Dahlberg said researchers can use the knowledge gained from this project to search for drought genes in other cereal crops.
“That has implications for feeding the world, particularly considering changing climate and weather patterns,” he said.
The massive dataset, collected from 400 samples of sorghum plants grown during 17 weeks at Kearney, reveals that the plant modulates the expression of a total of 10,727 genes, or more than 40% of its genome, in response to drought stress. Many of these changes occur within a week of the plant missing a weekly watering or after it is first watered after weeks of no precipitation or irrigation.
Kearney is a 330-acre agriculture research facility in the heart of California's Central Valley, where field-scale, real-world research can be conducted on drought impact on plants and soil microbial communities. The climate is naturally dry throughout the summer, making it ideal to mimic drought conditions by withholding irrigation water.
“People have really shied away from doing these types of experiments in the field and instead conduct them under controlled conditions in the laboratory or greenhouse. But I believe that the investment of time and resources that we put into it is going to pay off, in terms of the quality of the answers that we get, in terms of understanding real-world drought situations,” said Peggy Lemaux, UC Cooperative Extension specialist in UC Berkeley's Department of Plant and Microbial Biology and co-author of the paper.
To conduct the research, the team cultivated sorghum plants under three different irrigation conditions — pre-flowering drought, post-flowering drought and controlled applications of water — over three consecutive years at Kearney.
Each week during the growing season, members of the research team carefully harvested samples from the leaves and roots of selected plants and set up a mobile lab in the field where they could rapidly freeze the samples until they were processed for analysis. Then, researchers at JGI sequenced the RNA in each sample to create the transcriptome data, which reveals which of the plant's tens of thousands of genes are being transcribed and used to make proteins at particular times.
Finally, statisticians led by UC Berkeley statistics professor Elizabeth Purdom parsed the massive transcriptome data set to pinpoint how gene expression changed as the plants grew and were subjected to drought or relief from drought conditions.
“We very carefully controlled the watering conditions, and we sampled over the entire developmental timeframe of sorghum, so [researchers] could actually use this data not only to study drought stress, but also to study plant development,” Lemaux said.
The researchers noticed a few interesting patterns in the transcriptome data. First, they found that a set of genes known to help the plant foster symbiotic relationships with a type of fungus that lives around its roots was switched off in drought conditions. This set of genes exhibited the most dramatic changes in gene activity that they observed.
“That was interesting, because it hinted that the plants were turning off these associations [with fungi] when they were dry,” said John Vogel, a staff scientist at JGI and co-author of the paper. “That meshed well with findings that showed that the abundance of these fungi around the roots was decreasing at the same time.”
Second, they noticed that certain genes known to be involved with photosynthesis were also turned off in response to drought and turned up during drought recovery. While the team doesn't yet know why these changes might help the plant, they provide interesting clues for follow-up.
The data in the current paper show the plant's transcriptome under both normal conditions and drought conditions over the course of a single growing season. In the future, the team also plans to publish data from the other two years of the experiment, as well as proteomic and metabolomic data.
