How One Entomologist Found His Calling as an IPM Facilitator
(Entomology Today) Lina Bernaola, April 18
Alejandro Del Pozo-Valdivia, Ph.D., is currently an IPM entomology advisor at the University of California Cooperative Extension. He serves the vegetable industry in the Central Coast region of California by conducting applied research on pest management and implementing an extension program for stakeholders.
Alejandro was born and raised in Lima, Peru, where he earned his bachelor's degree in agronomy from La Molina National Agrarian University. Then, he went to Washington State University, where he obtained his master's degree in entomology working on integrated pest management (IPM) in irrigated hybrid poplars. In 2016, he obtained his Ph.D. in entomology at North Carolina State University (NCSU). During his doctoral studies, he worked on proposing management practices for the kudzu bug, an invasive pest of soybeans.
America's leading animal geneticist wants to talk to you about GMOs
(Pacific Standard) Emily Moon, April 18
At 11 a.m. on a Thursday morning, Alison Van Eenennaam is sitting in a harshly lit lab room, surrounded by her graduate students, talking about cattle sex—sex that, unfortunately, has not gotten anything pregnant. With the gene-editing techniques she's using, there could be many factors to blame: the location in the DNA strand of the edit, the biopsy performed to check the results of the edit, the freezing and the thawing of the embryo, the embryo's journey from lab to farm in a thermos. Now, Van Eenennaam floats another idea. "No foreplay, the poor guy," she says, a cheeky grin on her face. "The candle and the lighting wasn't right."

The University of California Cooperative Extension team in Novato has created an online "story map" that capsulizes in an interactive way its ongoing programs and key 2018 accomplishments, instead of a written annual report.
An Inviting Summary of UCCE Marin's Exploits
Why bees swarm and what you should – or shouldn't – do about them
(San Jose Mercury News) Rebecca Jepsen, April 16
…Last year was a particularly bad year for honey bees. Some bee keepers reported up to a 90 percent loss in their hives in 2018. Causes for this include varroa mite infestations, increased pathogens due to the warm weather, increased use of pesticides and a decrease in diversity of food sources.
So, what can we do about a swarm? “If you leave the bees alone, they will leave you alone.,” said Dr. Elina L. Niño, honey bee expert at UC Davis. “It only takes a few hours or at most a day or two for them to find and settle into their new home.”
Santa Maria expects big strawberry crop
(The Packer) Carol Lawrence, April 16
…Two of the three top-yielding varieties in production yield studies conducted in Watsonville by the University of California, Davis, include the monterey variety, producing 10,554 cartons per acre, and the san andreas variety, which yielded 10,414 cartons per acre. O'Donnell said the commission has noticed those varieties as well as some proprietary ones from growers.
“We're seeing more fruit per acre from when these fruits are planted,” she said.
A newer variety, the cabrillo, was reported as producing 11,605 cartons per acre in recent tests.
These California communities could be the next Paradise. Is yours one of them?
(Sacramento Bee) Ryan Sabalow, Phillip Reese and Dale Kasler, April 11
…“There's a lot of Paradises out there,” said Max Moritz, a fire specialist at UC Santa Barbara.
California's state-of-the-art building codes help protect homes from wildfire in the most vulnerable areas, experts say. But the codes only apply to new construction. A bill introduced by Assemblyman Jim Wood would provide cash to help Californians retrofit older homes.
“This will go a long way toward these different municipalities (in showing) that they deserve funding,” Moritz said.
U.C. Davis Animal Science Professor Discusses Agriculture's Contribution to Climate Change
(Cornell Sun) Stacey Blansky, April 11
On Monday afternoon, Prof. Frank Mitloehner, animal science and Air Quality Extension Specialist at the University of California, Davis, discussed the latest research surrounding animal agriculture and its “surprisingly modest” contribution to global greenhouse emissions. Mitloehner pointed at food waste as the largest contributor to environmental damage.
Scientists studying smoke taint as next fire season approaches
(Farm Press) Lee Allen, April 10
…A Los Angeles Times report on the subject put it this way - “Smoke taint rears its head when grapes, kissed by environmental smoke as they're growing, eventually yield a wine with unexpected smoldering flavors…, ‘like drinking from a well-used ashtray,'” using the words of University of California-Davis enology specialist Anita Oberholster. The story noted: “It's a vintner's worst horror movie nightmare - the smoke is coming from inside the grapes.”
Says Oberholster: “Compounds that are responsible for smoke taint are naturally present in grapes at low levels, they add complexity to the wine. Research into the subject is a slow process and to date, I can say there is very little you can do to prevent extracting smoke taint compound from grapes. We are currently in the process of evaluating different amelioration techniques from finished wines and there is some promise there, but research is still on-going, and I have no data yet.”
The farmer that saw his budding California tea farm go up in smoke
(San Francisco Chronicle) Jonathan Kauffman, April 8
…What Mike Fritts didn't know in 2010 — what almost everyone had forgotten, in fact — was that the UC Extension Service planted California's first modern test plot of Camellia sinensis in Fresno in the 1960s, when it partnered with Lipton.
Jacquelyn Gervay Hague, a chemist at UC Davis who conducts studies of tea-growing in Taiwan and is active in the university's Global Tea Initiative, said she learned about the plots just a few years ago when the director of UC Extension's Fresno office gave her a call.
“It blew my mind,” Hague says. She pored over the records, which covered 1963 to the early 1980s, when Lipton pulled out of the study. “It was concluded that we could grow tea very well,” she said.
Goats are the latest weapons in the war against wildfire
(CNN) Sarah Lazarus, April 8
… Lynn Huntsinger, professor of range ecology and management at the University of California, Berkeley, says that California has seen an increase in "fuel" -- the term fire experts use to describe "dead plants."
Huntsinger, who used to keep goats in the backyard of her Bay Area home, says the fire problem has its roots in history.
In the past, Native Americans lit fires to control the vegetation, she says. These deliberate burns created a landscape of open grasslands, so wildfires were smaller and less frequent.
That changed with the arrival of colonial settlers. They did not understand how "using fire prevented fire," and banned deliberate burns from around the turn of the 20th century, says Huntsinger.
The Age of Robot Farmers
(The New Yorker) John Seabrook, April 8
…To get an idea of what might be possible, I arranged to visit Professor David Slaughter in his office at the University of California at Davis. Slaughter leads the university's Smart Farm Initiative, which explores how future farmers might employ emerging technologies. Drones, for example, can automate the inspection of fields for pest or weed outbreaks, and can use high-resolution cameras and algorithmic processing of the images to pick up incipient problems before a farmer or a hired hand might spot them. Another possible application is plant breeding. Breeders currently rely on humans to evaluate seedlings produced by new combinations of already existing varieties.
…If the future of fruit-and-vegetable farming is automation, farmers will not only need the machines, and the funds to afford them, they will also require a new class of skilled farm workers who can debug the harvesters when something goes wrong. Mary Lou de Leon Siantz, a colleague of David Slaughter's at the University of California at Davis, is trying to ensure that domestic farmworkers' children have the STEM skills to compete for those jobs. De Leon Siantz is the daughter of Mexican immigrants; she has a Ph.D. in human development and focusses on migrant health in her research. She hopes to use existing Head Start and 4-H programs to teach math and engineering.
Regional sustainable groundwater management forum hosted in Corning
(Red Bluff Daily News) Julie Zeeb, April 5
Tehama and Butte counties teamed up Friday to host a Northern Sacramento Valley forum on sustainable groundwater held at Rolling Hills Casino.
The event was a collaboration between the Tehama County UC Cooperative Extension and Butte County Department of Water and Resource Conservation.
Allan Fulton, a Tehama County farm advisor, served as moderator.
“We're four years into Sustainable Groundwater Management Act that went into affect Jan. 1, 2015,” Fulton said. “There's been a lot of organizing (of groundwater management agencies). Now the governance structure and planning is underway. This venue is perfect for people to learn about the act and what is going on locally. It's a chance to see, as landowners and water operators, how to engage in the process and give feedback on what they think about it.”
The worst fire in California history illuminates fire preparation needs
(Yuba Net) April 5, 2019
Four months have passed since the Camp Fire, the worst wildfire in California history, ravaged bucolic communities in the Butte County foothills, including Paradise, Concow, Butte Creek Canyon, Cherokee, Yankee Hill and Magalia. Eighty-five people died, many of them elderly and unable to safely evacuate from an area where a wind-driven fire raced from home to home.
The unspeakable loss of human life and the serious challenges being faced by survivors has dominated the Camp Fire conversation. Now, UC Cooperative Extension is beginning a dialog with many agencies involved to understand how such tragedies can be prevented in the future.
UC course helps landowners track water use
(Farm Press) Tim Hearden, April 5
On a recent morning, Jim Edwards and about 70 of his fellow farmers and ranchers from Northern California went back to school. Each was handed a binder full of worksheets as they embarked on a three-hour course to learn how to measure and report their own water diversions – a state requirement now for landowners with rights to draw water from a river or stream.
There were lectures by University of California Cooperative Extension advisors and were even quizzes at the end of each unit so the landowners could demonstrate what they'd learned about open-ditch flow readings, measuring weirs, in-pipe flow meters, the calibration and accuracy of measuring devices, and measuring reservoir diversion quantities.
“I think it's great,” said Edwards, who takes water from Antelope Creek near Red Bluff to raise cattle, orchards and hay.
… “I think this is a good crash course to get people to understand flow measurements and what is required of them to report,” says Khaled Bali, a UCCE irrigation specialist who helps lead a course unit on device accuracy.
DIY with classes at the UC Cooperative Extension in gardening and food preservation
(New Times SLO) Camillia Lanham, April 4
A soft-hued planter full of pale gray-greens and purple flowers waits just through the gate of the Garden of the Seven Sisters off Sierra Way. Those winter colors will soon be replaced by flora made just for spring. This "curbside garden" is the first of 15 demonstration plots manned by Master Gardener Program volunteers at the UC Cooperative Extension in San Luis Obispo.
If you're a newbie like I am—or an oldie looking for some new tricks—the UC Cooperative Extension in San Luis Obispo County has got something just for you. Whether you're trying to figure out what to do with all of that extra produce on your kitchen counter or trying to decide exactly what to plant and when, there's probably a class for that either through the extension's Master Gardener Program or Master Food Preserver Program. You can become certified as a master and volunteer for either program or both programs, or you can dabble with a class here or there.
Backyard chickens hit hard by a long-gone, extremely contagious disease
(New Food Economy) Tove Danovich, April 4
In California, backyard birds are in lockdown. County fairs are canceling their poultry shows. Veterinary hospitals aren't accepting chicken appointments. Local 4-H leaders are telling chicken owners to keep their birds sequestered. Some poultry breeders are even worried their birds will need to be euthanized.
… There are approximately 100,000 backyard flocks in California according to Maurice Pitesky, Cooperative Extension poultry specialist with the University of California, Davis, School of Veterinary Medicine. “They don't focus so much on biosecurity, which is just a fancy word for disease prevention,” he says. Backyard poultry owners regularly mock the CDC's advice to avoid snuggling or kissing their chickens, but that's not the worst of it: 25 percent of urban poultry owners reported not even washing hands after handling their birds.

Dr. Monica Cooper, farm adviser of UC Cooperative Extension, Napa Valley, is the recipient of the American Society for Enology and Viticulture's (ASEV) Extension Distinction Award for 2019.
Cooper will receive the award at the 70th ASEV National Conference on June 19 in Napa, where she will be presenting, “Building Effective Extension Networks to Support Data-Driven Decision Making.”
It Wasn't Just the Soda Tax That Dropped Berkeley Soda Sales by 52 Percent
(The Inverse) Emma Betuel, April 3
University of California, Berkeley professor Sofia Villas-Boas, Ph.D., and Ph.D. candidate Scott Kaplan show in the new paper that soda purchases fell between 10 and 20 percent on Berkeley's campus directly after the soda tax was passed but before the prices officially increased in 2015. They also used Nielsen data to show a similar pattern: soda purchases at local stores decreased by 10.8 percent even before the higher prices went into effect.
“The election outcome caused a 10-20% reduction in sales of regular soda beverages before consumers faced higher prices anywhere, on campus or in stores off-campus,” Kaplan tells Inverse, “This suggests that you might not witness these types of effects if a sugar-sweetened beverage (or soda) tax was implemented without a preceding campaign and public vote.”

Tiny whiteflies seem to be bugging people across the Central Coast, but why are there so many this year?
(KSBY) Megan Healy, April 1
A master gardener from the SLO University of California Cooperative Extension says dozens of people from south SLO County called asking why there are so many.
“It's probably a reflection of the increasing temperatures coming on top of all that nice water we have had, so we have had a flush of vegetation and the flies that came from eggs originally have just all hopped out,” said Cathryn Howarth, a master gardener a the SLO County UC Cooperative Extension.
According to the UC Agricultural and Natural Resources Statewide Integrated Pest Management Program, signs of whitefly manifestation include…
Inside the race to build the burger of the future
(Politico) Michael Grunwald, April 1
…Conglomerates like Walmart, McDonald's and General Mills have been setting emissions reduction targets for their suppliers, which will ratchet up pressure on farmers and ranchers to green their operations. But at a time when they're already getting squeezed by a handful of giant agribusinesses that process their animals, as well as the economic fallout from President Donald Trump's trade wars, they're hoping for government incentives to reduce their emissions. Frank Mitloehner, a professor of animal agriculture at the University of California-Davis, believes farmers and ranchers deserve to be paid for their ecological services—and recently said so to an Ocasio-Cortez staffer. For example, California is spending hundreds of millions of dollars to help them manage their manure in cleaner ways, which makes more sense to Mitloehner than demonizing them for the messes they make while putting food on people's tables. Many of them are conservative Republicans who deny climate science, but they're also pragmatic businesspeople—Mitloehner says they could store tremendous amounts of carbon on their lands if the price and the politics were right.
“Politically, farmers tend toward the Trump camp, and when they hear all this finger-pointing about farting cows, they just shut down,” Mitloehner says. “It troubles me, because I know how urgent this climate discussion is.”
… “There's such an enormous opportunity to reduce emissions in meat production, if you didn't hear all this counterproductive talk about how everything about it is terrible,” says Mitloehner, the Cal-Davis agricultural scientist. “Let's not alienate the people we need the most on our quest for a climate solution.”
Two UC Agriculture and Natural Resources emeritus specialists, two UC ANR advisors and a UC ANR vice provost spent a week in March working in Guatemala to help implement a USDA-funded (UC Davis-managed) project that is rebuilding the extension system in Guatemala.
With a population of almost 17.5 million and a per capita income ranked 118th in the world, Guatemala is working to improve the livelihoods and incomes of it's rural population, which represents nearly half of the total population. The project is being implemented in Guatemala with the Universidad de San Carlos. Universidad de San Carlos is the biggest and oldest university in Guatemala and which - when established in 1676 - was the fourth university established in the Americas. The 150,000-student university includes a prominent and well-known agricultural school.
The UC contingent delivered modules on extension and marketing, two of five required for the participants to receive a certificate. Jim Hill, emeritus rice specialist based at UC Davis, is leading the second phase of the project.
The rest of the team for the week were Steve Temple, emeritus agronomy specialist, UC Davis; Jairo Diaz, director, UC Desert Research and Extension Center; Ramiro Lobo, advisor, UC Cooperative Extension, San Diego County; Mark Bell, vice provost, strategic initiatives and statewide programs; and Kate Lincoln, CAES Global Engagement, UC Davis. Bell led the project when he was part of the UC Davis College of Agricultural and Environmental Sciences.
The interactive week-long course worked with 31 participants, mostly from the Guatemalan Ministry of Agriculture extension offices, but also included agriculture teachers. The team shared the essential steps and associated skills required for successful extension. The course used the Spanish acronym ASISTE as a framework (previously developed by Mark Bell, Maria Paz Santibanez and Elana Peach-Fine) as an easy way to remember the key steps. ASISTE stands for audience (audience), soluciónes (solutions), información simple (simple information), transferencia (transfer), and evaluación (evaluation).
As part of the course, participants developed and delivered their own mini-workshops using local issues and context to reinforce workshop discussions. As Guatemala has a large indigenous population with more than 20 languages, one of the participants delivered his talk in Tzutuhil, the main language used for his constituents in Santiago Atitlan, Sonora department.
Western Innovator: Putting biologicals to work
(Capital Press) Padma Nagappan, March 11
Early in life, Surendra Dara decided that no matter which field he chose, he needed to make an impact on it. Always interested in science, he chose agriculture and specialized in entomology.
“It attracted me because it dealt with arthropods and there are a lot of physiological similarities to the human world,” Dara said. “It was also critical for growing food and feeding humans.”
Dara is now an entomopathologist with the University of California's Division of Agriculture and Natural Resources in San Luis Obispo, and has an established reputation for exploring innovative options to control pests using microbials as biological controls, and showing growers how they can also help with plant growth, drought resistance and fighting diseases.
Group linked to Ocasio-Cortez seeks ag input after Green New Deal backlash
(Politico) Helena Bottemiller Evich, March 11
After watching that drama unfold, Frank Mitloehner, a leading scientist on agricultural emissions at the University of California, Davis, was thrilled when two outreach staff affiliated with AOC's network reached out to set up a call to discuss the potential for climate mitigation efforts in agriculture. The call, held earlier this month, lasted more than an hour, Mitloehner said.
“I was very glad to inform of what I know, and they were very receptive to it,” Mitloehner said on Agri-Talk last week. During the segment, he urged agricultural producers to not dismiss the left-wing climate effort.
Sudden surge in an unusual crime in Fresno County: Goat theft
(LA Times) Hannah Fry, March 11, 2019
…Picquette's two sons have been raising goats for the last five years as a 4-H project. Losing their animals has been especially hard for the boys, Picquette said, adding that they had planned to use money won during competitions to pay for college.
“They feel very violated. They don't understand how somebody could just come and take something they worked so hard for,” she said. “The bond we have with the goats is incredible. I'm just heartbroken. I don't know if they're scared or hungry. … They've always been treated so well.”
California's ambitious plan to stop deadly wildfires may not be enough, experts say
(SF Chronicle) Kurtis Alexander, March 9
… “It's not fair to say that fuel treatments won't do any good,” said Max Moritz, a UC Cooperative Extension wildfire specialist at UC Santa Barbara. “It may provide some protection in some places. But most of us studying this agree that you can't just do this and (expect to) make much headway.”
The plan by the California Department of Forestry and Fire Protection, or Cal Fire, comes at the request of Gov. Gavin Newsom. On his second day in office, Newsom asked the agency to develop a proposal to address the increasingly destructive fire seasons that have rattled the state and are expected to worsen with climate change.
…In the meantime, many researchers say the most effective approach to fire protection is not in the forests, but in communities. They recommend making homes more resistant to fire with hardier construction materials, and clearing the vegetation around them.
“You have to address the home vulnerabilities themselves,” said Moritz at UC Santa Barbara. “If you don't, you're just not going to make a lot of progress on fire.”
After more than 140 years, a massive fig tree gracing the plaza where Los Angeles was founded collapses
(LA Times) Matthew Ormseth, March 9
… The four figs were planted at El Pueblo by agriculturalist and City Councilman Elijah Hook Workman, KCET reported in 2013. The Ficus macrophylla was brought from Australia to Southern California in the 1860s and 1870s, probably to provide shade and ornamentation, said Donald Hodel, a horticulture advisor for the University of California's Cooperative Extension.
Hodel described the Moreton Bay fig as a commanding breed of tree with an enveloping canopy that threw plenty of shade.
His reasons for admiring the Moreton Bay fig: “Their grandeur; their size — they have an imposing habit; their root structure is incredible; the spreading nature of their branches.”
Hodel said he last saw the El Pueblo figs about six years ago.
“I wasn't too impressed by their health or their size, considering they're 140-something years old,” he said.

4-H leader who taught lost Benbow girls outdoor skills being flown to Washington, DC for recognition
Kym Kemp, March 7
When Leia Carrico, age 8, and her sister, Caroline, age 5, disappeared into the woods around their home near Benbow on March 1, the whole nation held its breath for the next 44 hours until they were found. But, though their 4-H leaders were worried, too, they say they also knew the girls had something many other children don't–they had survival skills from a class taught by their Outdoor Adventures 4-H project leader, Justin Lehnert.
Lehnert is being honored in Washington, DC, on Tuesday for his role in teaching Leia and Caroline outdoor skills.
Researchers highlight plan to eat healthy on a budget
(Consumer Affairs) Kristen Dalli, March 7
Following a healthy diet can come with a hefty price tag, but a team of researchers has outlined a way for consumers to stick to a healthy diet -- and also stick to their budgets.
According to the team, consumers -- and their families -- can have healthy meals if they focus on buying items in bulk and planning meals in advance.
“This study determines the likelihood that families living in low-income households could create meals that meet the USDA dietary guidelines presented in MyPlate nutrition education materials,” said researcher Karen M. Jetter, PhD. “In addition to food cost, the other factors considered were access to stores, time for meal preparation, and whether the menus included culturally appropriate foods.”

Sorry, Alexandria Ocasio-Cortez, but “farting cows” aren't the problem
(New Food Economy) Sam Bloch, March 7
…As it turns out, neither side was accurate. Republicans are likely to continue linking Green New Deal priorities to a supposed hamburger ban. But if you don't hear about cow farts anymore from AOC, it may not be because of GOP criticism. Frank Mitloehner, an animal scientist and air quality specialist at the University of California, Davis, insists cattle flatulence isn't the problem it's made out to be, and says he helped set the record straight.
Here's what seems to have happened. On February 4, shortly before Ocasio-Cortez announced the Green New Deal, she was speaking to school children in Queens, New York. When one asked how they could “combat” climate change, Ocasio-Cortez offered two practical options—stop using disposable razors, and skip meat and dairy for one meal.
Mitloehner tweeted at her.
“Dear @AOC: we all try to help the climate,” he wrote. “However, the two options you offered have low impacts compared to the 800lb gorilla, which is to reduce fossil fuel use. About ⅔ of greenhouse gas emissions in the US stem from transport and energy prod&use. Meat/milk = 4 % of total GHG,” referring to findings in a recent EPA report.
… “I give her team a lot of credit for reaching out,” Mitloehner says. “If we really are serious about making a difference in carbon emissions, you cannot do this without agriculture involved.”
California supplies a quarter of the world's sunflower seeds
(Capital Press) Padma Nagappan, March 7
…Khaled Bali is a University of California Department of Agriculture and Natural Resources statewide water and irrigation specialist who has been working since 2016 on a four-year trial on sunflower varieties.
He was asked by the University of Georgia to help ascertain which varieties were drought resistant. He chose to conduct his trial in the low desert region of the Imperial Valley, since it gets little rain during the growing season between February when it's planted, and June when it's harvested. This would make it easier to control and measure the actual water applied to the crop varieties.
“We're looking at 285 varieties of sunflowers, to see which ones do well under stress,” Bali said. He has tested different plantings each growing season for the past three years, and will finish the trial this year.

Bees, blooms off to slow start
(Western Farm Press) Logan Hawkes, March 6
…This year, almond bloom started around a normal time, with some early varieties showing a few open flowers in the first week of February,” reported Franz Niederholzer, UCCE farm advisor for Colusa, Sutter, and Yuba Counties. “For most of the month bloom progressed very slowly,”
By the middle of February, he says, “bloom for Nonpareil was at least two weeks behind, and bee hours were limited until the last week of the month. Last year, between Feb 1-20, we accumulated 130 bee hours of good honey bee flying weather [55 F., no rain, and wind less than 10 mph]. For the same interval this year, we had around 10 hours and only six of those occurred with open flowers in the orchard.”
On the positive side of the slow start, Niederholzer says, the colder weather tends to suppress activity of key bloom diseases such as blossom brown rot and anthracnose. “However, cold weather at bloom was conducive to blossom blast (pseudomonas) bacteria, and some growers were considering adding materials to their normal bloom fungicides with bactericide activity.”
Wet winter aids groundwater replenishment
(Ag Alert) Christine Souza, March 6
… Helen Dahlke, a hydrology expert and professor with the University of California, Davis, Department of Land, Air and Water Resources, has been working with farmers, studying on-farm groundwater recharge locations and suitability for various crops.
"In many regions, we can definitely do more actively recharging our groundwater aquifers," said Dahlke, who currently has trials on alfalfa at the UC Kearney Agricultural Center. "It really depends on what region, how much surface water is available for recharge, what kind of sediment structure or hydrogeology we have underneath and whether it's suited for conveying large amounts quickly."
Despite abundant precipitation in recent weeks, she said the timing is not the best for studying impact of recharge on certain crops.
"We prefer on-farm recharge to happen in January and February, just because that is considered the dormancy season for most crops," Dahlke said. "With almond trees already blooming, often there is a greater risk of applying water on those crops."
She said recent precipitation has helped groundwater recharge overall, but there is "very little way of estimating how much it is helping."
Drip irrigation improves yields of Imperial sugar beets
(Ag Alert) Padma Nagappan, March 6
Halfway through a two-year irrigation trial to test furrow irrigation versus drip on sugar beet in California's Imperial Valley, Ali Montazar is looking for ways to boost yields with as little water consumption as possible in a region where furrow irrigation is the common practice.
Montazar, irrigation and water management advisor with the University of California department of agriculture and natural resources (UCANR) in Imperial County, is comparing and evaluating sugar beets for crop water use, sugar percentage, and yield, using both furrow and drip, since growers are now thinking of switching to subsurface drip.
Preliminary results from year one of the trial show that yield and crop water use are better with drip. Yield was 21 percent higher, and water use was a few points lower.
NFU says “No” to Green New Deal
(DTN) Jerry Hagstrom and Chris Clayton, March 6
Frank Mitloehner, an animal-science professor and air-quality Extension specialist at the University of California-Davis, reached out to Ocasio-Cortez's team about agriculture and the Green New Deal after seeing social media posts late last month about “farting cows” that drew a great deal of attention.
“I appreciate her interest in climate-change mitigation, but the 800-pound gorilla is the use of fossil fuels, and I told her that even the notion of cow flatulence makes this whole thing sound silly, and that's not what we need this discussion to be,” Mitloehner told DTN in an interview.

Ocasio-Cortez Seeks Ag Data on Green New Deal
(Drovers) John Herath, March 4
When freshman congresswoman Alexandria Ocasio-Cortez released her Green New Deal plan, social media lit up with talk of her plan's mentions of “farting cows.” That drew the attention of agriculture's preeminent expert on air quality, Dr. Frank Mitloehner of the University of California at Davis, who tweeted back at the congresswoman.
“I don't know whether my tweet was the reason, but a few hours after I tweeted her, all mentioning of cow flatulence were taken off the web pages and of all social media outlets and was never to be heard again,” Mitloehner told Chip Flory on the AgriTalk Radio Show Monday.

Eructation Inflation: Greenhouse Gas Emissions of Livestock
(Science for the Rest of Us) March 1
Put your nerd hat on -- we cover a lot of ground in this fast-paced discussion with Dr. Frank Mitloehner of the University of California-Davis about the greenhouse gas emissions associated with the meat and dairy we consume. We consider how livestock emissions compare to other sectors of the US and global economies, the carbon footprint of vegetarian diets and what is the most effective way to reduce individual carbon emissions.
Keeping the Carbon Footprint of Livestock in Perspective
(AgNet West) Brian German, March 1
…“It is irresponsible and it's misguiding the public to believe that the true sources of pollution are downplayed, and the impacts of animal agriculture are grossly inflated,” said Dr. Frank Mitloehner, Professor and Air Quality Specialist in Cooperative Extension in the Department of Animal Science at the University of California, Davis.
Five California leaders, including two UC Cooperative Extension scientists, were recognized for their contributions to the field of agriculture and climate change at the California Climate & Agriculture Summit at UC Davis on March 5, 2019, said a news release issued by California Climate & Agriculture Network (CalCAN).
The summit was organized by CalCAN and brought together some of the state's foremost experts in agriculture — including farmers, agriculture professionals, researchers, advocates and policymakers — to grapple with the challenges of climate change and share knowledge about the opportunities facing the industry.
At the summit, CalCAN presented the leadership award for agricultural professional to Ruth Dahlquist-Willard, UC Cooperative Extension small farms advisor in Fresno and Tulare counties.
Dahlquist-Willard helps keep small-scale, diversified farmers in business by providing support with marketing, regulatory compliance, processing of value-added products, water and energy efficiency, and integrated pest management. She has been a driving force behind increasing access by Hmong farmers in the Fresno area to California's State Water Efficiency and Enhancement Program (SWEEP). Dahlquist-Willard has promoted the program, provided thousands of hours of one-to-one, culturally-relevant support to farmers on grant applications, and assisted with project design and installation. The farmers she has supported are now benefiting from water, energy and financial savings.
"There are large environmental problems to solve in the Central Valley, and it's time for a different conversation around farming there," Dahlquist-Willard said. "I feel that there needs to be a conversation in the middle to solve problems rather than a conflict-based approach."
The leadership award for researcher was presented to Tapan Pathak, UC Cooperative Extension specialist for climate adaptation in agriculture, based at UC Merced.
Pathak is the chair of the UC Cooperative Extension Climate Change Adaptation Workgroup, which brings together scientists across the UC system to collaborate on research and extension projects related to climate change adaptation in California agriculture. Pathak is the lead author on an important and timely paper that was published in 2018 in the journal Agronomy. It synthesizes the impacts of climate change on California agriculture and offers directions for future research and implementation.
"We need more facilitated dialog with policy researchers and scientists on the science of climate change, and the implications of not taking action," Pathak said. "Given the scale of California agriculture and the pressure of climate change impacts, we need even more substantial funding for incentives for farmers and for research and tools, and we must integrate growers from the beginning of the process."
The other CalCAN leadership awards were presented to the following:
Leadership Award for policymaker: Ken Alex, former Director of Governor Brown's Office of Planning & Research
Leadership Award for farmer/rancher: Ward and Rosie Burroughs, Burroughs Family Farm (Denair, CA)
Leadership award for legislative staff: Brett Williams, Office of Assemblymember Jacqui Irwin
California is searching for solutions to the wildfire crisis. Livestock ranchers believe they can help.
At the 14th Annual Rangeland Summit in Stockton in January, more than 150 ranchers, public land managers and representatives of non-profit organizations that work on land conservation gathered to share research and experiences that outline the value of cattle and sheep grazing on rangeland.
Since California was settled by Europeans, cattle and sheep have been an integral part of the state's history.
“Cattle can control brush,” said Lynn Huntsinger, UC Cooperative Extension specialist at UC Berkeley in a presentation on brush management. She discussed research she conducted in the early 1980s to understand the role of cattle in Sierra Nevada brush control.
“We need to make livestock into firefighters,” she said. “Constant, deliberate, targeted grazing is needed for fire management.”
However, thick, overgrown brush requires intensive treatment that cattle can't handle on their own.
“You have to start from a good place,” Huntsinger said. “Start early, such as post fire. Plan when you have a blank slate for the forest you want.”
The tragic loss of homes and lives to wildfire in the last few years has increased the public demand for answers and action. However, the reasons for greater frequency and intensity of wildfire are not well understood.
“Is it climate change? Past decisions? Land use? What can we do about it?” asked UC Cooperative Extension specialist Van Butsic. “Research.”
At the summit, Butsic presented the results of his recent research to determine whether ownership has an impact upon whether land will burn. He and his colleagues studied the burn histories of forest and rangeland areas that were matched with the same characteristics, except in ownership.
“We controlled for all factors – slope, elevation, the likelihood of ignition,” he said. “We found that on forest and rangeland, federal ownership led to .3 percent higher fire probability. Ownership is dwarfing the impact of climate change.”
There is still much more research to be done.
“We can't say the impact of grazed vs. ungrazed land,” Butsic said. “We also need to look at fire severity as well as fire frequency.”
The UC Cooperative Extension advisor in Modoc County, Laura Snell, shared preliminary results at the rangeland summit that provide information for landowners making decisions about returning livestock to burned areas.
She and a team of colleagues studied the fire history of U.S. Forest Service and Bureau of Land Management rangeland in Lassen and Modoc counties where fires had burned through 5, 10 and 15 years before. The dataset included information about whether the land was “rested” for two years after the fire, or whether livestock were returned to graze soon after the blaze.
The scientists set out to determine whether fire intensity and climate at the site (measured by soil temperature and moisture) had an impact on the future diversity of plant species and growth of cheat grass, an invasive species that animals don't like.
“No matter what we did, graze or not graze, after 15 years, the species richness stayed the same,” Snell said. “Grazing was not the driving factor.”
The results are also important in terms of fuels accumulation and the prevention of future wildfires.
“Federal land managers have typically used a policy to rest the land for two years after a fire. During the interval, the fuels sometimes burn again and livestock producers have to wait another two years,” Snell said. “Our research showed you don't necessarily need to rest the land after the fire.”
Two ranchers who were recently impacted by wildfire presented their experiences and perspectives during the rangeland summit.
Mike Williams of Diamond W Cattle Company had livestock on 6,500 acres of leased land in Ventura County when the Thomas Fire ignited on Dec. 4, 2017. Over more than a month, the fire burned 281,893 acres and consumed 1,000 structures.
Williams had stockpiled feed on certain pastures by limiting grazing, which during the fire turned into hazardous fuel.
Adam Cline, rangeland manager for the Yocha Dehe Wintun Nation Preserve in the Capay Valley, had a similar experience when the County Fire burned more than 90,000 acres in western Yolo and eastern Napa counties in June and July 2018. To reserve feed for later, Cline had left 2,500 pounds per acre of residual dry matter on grazing land as a drought mitigation strategy. He said he plans to reconsider this grazing plan.
“Now, cattle feed looks like a lot of fuel,” he said.
