UC helps growers comply with new regulations

(Farm Press) Tim Hearden, March 27

A few months ago, while I was working with Todd Fitchette on a special package we were doing (or, he was doing and I was pitching in on) that focused on the 50th anniversary of the Citrus Research Board, I wrote a column about the benefits of land-grant universities such as the University of California (UC).

It's not an overstatement, I wrote, that the vast network of UC Cooperative Extension offices and research facilities has enabled agriculture in the Golden State to survive amid daunting challenges.

Expert: Speak up now about agriculture's carbon footprint

(Leader Telegram) Brooke Bechen, March 25

Dr. Frank Mitloehner, a professor and air quality extension specialist in the Department of Animal Science at the University of California-Davis, isn't afraid to speak up, particularly on Twitter where he writes under the handle @GHGGuru. He sees 2.5 million people visiting his Twitter account each month, which provides accurate information on air emissions and busts myths distributed by those looking to attack animal agriculture.

“Being in California is like being at Ground Zero,” he said. “There are urban centers of people who think they're food experts, but most of these people have never set foot on a farm and don't know anything about agriculture.

Wildfire Speaker Series Tonight: Fire Resistant Homes & Defensible Space

(YubaNet) March 25

…Dr. Kate Wilkin is the new Forest and Fire Adviser with UC Cooperative Extension in Butte, Nevada, Sutter, and Yuba Counties. She recently moved here from Berkeley, CA where she was postdoctoral researcher focused on wildfire emissions and fire-forest-water relations. Her PhD, also at UC Berkeley, focused on the efficacy of fuel treatments in Northern California shrublands to reduce fire hazards and on mixed conifer forest-fire-water and fire-biodiversity relations. Before moving to California, Kate grew up in rural Appalachia and then explored other fire-prone regions of the US as a natural resource manager and prescribed fire burner on public and nonprofit lands. Based on these experiences and more, she knows that we need to use solutions responsibly, both old and new, to solve our forest health crisis. Kate will be focusing on incorporating fire safe concepts into residential landscaping.

Landowners aim to fight fire with fire

(Benito Link) Blaire Strohn, March 19, 2019

The 2018 wildfire season in California was devastating, which left local landowners to consider how future blazes can be prevented. Their solution: more fire.

On March 14, The San Benito Working Landscapes Group and the UC Cooperative Extension (UCCE) hosted a meeting to discuss prescribed burning on San Benito County rangelands.

…UCCE livestock and natural resources advisor Devii Rao said the meeting also looked at Cal Fire funding and prescribed burn associations. She mentioned that last year former Gov. Jerry Brown signed two pieces of legislation related to prescribed burning:

Senate Bill 901 provides Cal Fire $1 billion for forest health, fuel load, and prescribed burns over five years, including $35 million a year for prescribed fire and other reduction projects.

Senate Bill 1260 requires Cal Fire to collaborate with public and private landowners on prescribed burns. They must also create a program for pre-certification for a “burn boss,” a private contractor that has experience in prescribed burning.

…In June, Rao will co-host a meeting with Lenya Quinn-Davidson and Jeff Stackhouse from UCCE Humboldt County. The meeting is expected to focus on how to develop a prescribed burn association, in addition to a small burn demonstration on a local private ranch.

A More Humane Livestock Industry, Brought to You By Crispr

(Wired) Gregory Barber, March 19

Hopes were running high for cow 401, and cow 401 serenely bore the weight of expectations. She entered the cattle chute obligingly, and as the vet searched her uterus, making full use of the plastic glove that covered his arm up to his shoulder, she uttered nary a moo. A week ago, Cow 401 and four other members of her experimental herd at UC Davis were in the early stages of pregnancy. But now, following a string of disappointing checkups, it was all down to her. Alison Van Eenennaam, the animal geneticist in charge of the proceedings, kept watch from off to one side, galoshes firmly planted in the damp manure, eyes fixed on a portable ultrasound monitor. After a few moments, the vet delivered his fifth and final diagnosis. “She's not pregnant,” he said. Van Eenennaam looked up. “Ah, shit,” she muttered.

Climate change is hurting migrating waterbirds across the West. It could get worse

(Sacramento Bee) Andrew Sheeler, March 18

…Some birds, like the black-necked stilt and the sandhill crane, which breed early in the season, have thrived in the warming climate, said Mohammad Safeeq, a hydrologist with the Sierra Nevada Research Institute and an adjunct professor at UC Merced.

But others suffer. That includes the killdeer, the Wilson's snipe, the black tern, and the western and Clark's grebe.

“We have looked at 14 species and among eight open-water and shoreline foraging species that have undergone significant population declines, five were negatively associated with temperature increases,” Safeeq said in an email interview.

US researchers moving abroad to avoid FDA's CRISPR-edited animal regulations

(Genetic Literacy Project) Cameron English, Alison Van Eenennaam, March 14

One day soon, farmers may be able to raise food animals immune to deadly diseases and spare them painful but necessary procedures like horn removal. These innovations, made possible by CRISPR and other gene-editing techniques, could cut the cost of food production, reduce antibiotic use in agriculture and dramatically improve animal welfare. But federal regulation may very well stifle these developments in the US.

In 2017, the Food and Drug Administration (FDA) proposed a plan to regulate gene-edited animals as veterinary drugs under the 1938 Food, Drug and Cosmetic Act, because their DNA is “intentionally altered.” The proposal has drawn harsh criticism from animal scientists, some of whom are packing up their labs and leaving the US to avoid the FDA's rules. Food animals, these experts say, should be regulated based on the risk they pose to human health, not the breeding method that produced them.

Corky Anderson's energy, innovation helped save California's pistachio industry

(Bakersfield Californian) Steven E. Mayer, March 13

"Corky was an important player in the early pistachio industry," said  a Kern County farm adviser with the UC Cooperative Extension who specializes in citrus and pistachios.

"And he was a great cooperator," Kallsen said. "He allowed lots of test trials on his properties."

… In 1980, Anderson and Puryear's first patented rootstock changed the industry, said Kevin Blackwell, general manager of Pioneer Nursery, the wholesale business founded by the two entrepreneurs.

 "In our heyday, we were selling a million trees a year," said Blackwell, who said he has known Anderson for 47 years.

No one does it alone, Kallsen noted. Anderson built and refined his patented rootstock based on earlier research by the University of California.

Farmers protect crops in rain's aftermath

(Ag Alert) Ching Lee, March 13

Franz Niederholzer, University of California Cooperative Extension farm advisor in Colusa, Sutter and Yuba counties, said though cold weather does reduce the risk of most fungal diseases, other problems such as bacterial blast and jacket rot—also a fungal disease—are more prevalent during cool weather.

Cooler weather, however, does help to extend the bloom, he said. That allows farmers more time to apply fungicide, which is recommended at the beginning of bloom and again at full bloom, he said.

Brent Holtz, UCCE farm advisor in San Joaquin County, said he hasn't seen too many problems with fungal diseases at this point, because of how cool it's been, but there have been more incidents of bacterial blast, which can infect trees under stress. In orchards with high nematode populations, the bacteria can enter wounds on the surface of the plants created by frost, he noted.

"It blights the blossoms, and if the blossom is dead, they don't produce fruit," Holtz said.

California's super bloom attracts swarms of migrating butterflies

(CNN) David Williams, March 13

"I saw more butterflies in the last 10 minutes than I've seen my entire life," Jason Suppes of UC South Coast REC wrote on Twitter.

This year's wildflower super bloom is not only filling California deserts with eye-popping displays of color -- it's also providing a feast for swarms of painted lady butterflies making their way north from Mexico.

"This is the biggest outbreak since 2005," said Art Shapiro, a professor at the University of California, Davis, who's been studying the migration of butterflies in the state since 1972.

…"I saw more butterflies in the last 10 minutes than I've seen my entire life," Jason Suppes wrote Tuesday on Twitter. Suppes is an education specialist at an agricultural research facility in Irvine.

Grape growers continue push to mechanize

(Western Farm Press) Lee Allen, March 13

…In Fresno, growers affiliated with the San Joaquin Valley Winegrowers Association met to discuss the latest UC research on incidents of disease and machine injury to trunks and rootstock.

… “Growers are having a hard time finding workers to maintain their vineyards and increasing labor costs are challenging grape-farming's economic sustainability,” says UC Cooperative Extension viticulture advisor George Zhuang.  “We're studying the use of machines to reduce the number of people needed to perform tasks like pruning.

“Because canopy architecture and yield characteristics involving mechanically-pruned vines are much different from those that are hand-pruned, water and fertilizer requirements for the mechanically pruned vines can be quite different. Performance of different rootstocks in mechanical pruning systems is critical for both yield and fruit quality of grape production in the San Joaquin Valley.”

…Kaan Kurtural, UC Cooperative Extension viticulture specialist in the UC Davis Viticulture and Enology Department, whose research involves improving vineyard production efficiency through canopy and crop load management via mechanization, says the case for switching out hand labor with machines gets stronger with growers using such mechanization for pruning, suckering, and removing shoots and leaves.

“Mechanical pruning can produce more stable year-to-year fruit yields of better quality than traditional and more costly hand pruning spurs or canes.” His comments were based on a Kern County two-year research trial looking for ways for growers to reduce both cost and water use.

Above average rainfall in February benefits strawberry crops in the Central Valley

(ABC 30) Reuben Contreras, Feb. 28

…Above average rainfall in February will help this year's harvest last through October. 
"It looks like it is in full bloom right now and it looks like it is going to rain. So we need the water as much as we can right now," said Michael Yang, University of California Cooperative Extension. 
He works with small farms and specialty crops in the Hmong community, including a strawberry field in Northeast Fresno near Willow and Behymer. 
Yang said the rain will add to the groundwater supply most farmers use to grow their crops plus it will help make the strawberries sweeter.

UC Davis, wine industry cultivate relationship

(Fruit Growers News) Robin Derieux, Feb. 13

Under the hot summer sun of the San Joaquin Valley, just south of Merced, Miguel Guerrero of The Wine Group is trying a new high-wire act. In collaboration with University of California-Davis Cooperative Extension, Roduner Ranch vineyard manager Guerrero is experimenting with Cabernet Sauvignon vines and other varieties elevated by a single wire at 66 inches – plantings that are 2-3 feet higher than the traditional winegrape canopy.

…“The beauty of the high-wire system is that the fruit zone is really defined – a solid wall of grape clusters – and the pruning machine can just zip right alongside the vines,” said Kaan Kurtural, a UC Davis Cooperative Extension viticulture specialist. “We can carry more crop, and with mechanical leaf removal, we get that sun-dappled exposure that feeds the fruit. Less leaf cover means the vines require less water, and the grape quality is much better.”

There's Still So Much We Need To Learn About Weed—And Fast

(Wired) Matt Simon, Feb. 11

… But late last month, UC Berkeley opened the Cannabis Research Center to start tackling some of these social and environmental unknowns. With its proximity to the legendary growing regions of Northern California, the center can start to quantify this historically secretive industry, measuring its toll on the environment and looking at how existing rules affect the growers themselves. The goal is to create a body of data to inform future policies, making cannabis safer for all.

… So for the past few years Van Butsic, codirector of the Cannabis Research Center, and his colleagues have been sifting through satellite images to pinpoint those unaccounted-for farms. “We have an army of undergraduates who look at high-resolution imagery and digitize how big the farms are, how many plants we can see,” Butsic says. Because cannabis plants love light, growers usually keep them out in the open. The researchers still miss many trespass growers, however, who tend to hide their plants in the brush to avoid detection.

Broomrape Weed Spreads Quickly

(AgNet West) Taylor Hillman, Feb. 8

By the time you see broomrape weed in your fields, it may be too late. There has been a resurgence of broomrape reports over the last decade in California. Retired UC Cooperative Extension Farm Advisor Gene Miyao said although the parasitic weed is far from widespread, it could become so quickly. “The seeds are very small, the growth is primarily underground until it starts sending up shoots and then it very quickly starts setting seed,” he said. “A single seed attached to a tomato plant may send up half-a-dozen shoots, and each shoot might have 1,000 seeds or more.”

New CA Bill Aims to Help Prepare Farmers for Extreme Weather, Changing Climate

(YubaNet) CalCAN, Feb. 7

The state and University of California have made significant investments in research to better understand agriculture's unique vulnerabilities and adaptation strategies to a changing climate, including in the state's recently released Fourth Climate Change Assessment. But not enough has been done to translate climate risks to the farm level and assist farmers in adapting to climate change.

…The bill would also fund trainings for technical assistance providers and agricultural organizations. According to a 2017 survey of 144 University of California Agriculture and Natural Resources staff, 88% of respondents believe it is important to incorporate climate change information into farm extension programs, but only 43% actually do. Respondents cited a lack of access to climate information relevant to farmers and expressed interest in education on technical tools and information resources.

Drought concerns loom for California farmers, ranchers despite recent rain

(KSBY) Dustin Klemann, Feb. 6

Even with the onslaught of rainy weather, the U.S. Drought Monitor states San Luis Obispo County and Santa Barbara County remain in a moderate drought.

On Wednesday, the UC Cooperative Extension held a workshop in Solvang titled “Weather, Grass, and Drought: Planning for Uncertainty.”

“Leave it to a drought workshop to bring the rain,” Matthew Shapero joked. He is a livestock and range advisor for UCCE.

Shapero pointed out a call he received questioning the monitor's accuracy on a local level.

“He said ‘I really don't think the drought monitor accurately reflects what I am seeing on the ground.'”

… “We Californians are constantly accused of not having seasons. We do,” said Dr. Royce Larsen, an advisor of the UCCE. “We have fire, flood, mud, and drought. That's what we live with. And it's getting more and more so every year.”

These days, it seems everyone is looking for a silver bullet solution to California's drought. Some advocate increasing supply through more storage, desalination or water reuse. Others propose controlling demand through conservation or restriction of water use by urban and agricultural users.

Camp Fire: When survival means shelter

(Mercury News) Lisa Krieger, Feb. 2

“We have to talk about it, as a community, to reduce vulnerability – especially for citizens who don't drive,” said Scott Stephens, co-director of UC-Berkeley's Center for Fire Research and Outreach. “In the Camp Fire, people didn't die because they wanted to stay. They had to stay. All of a sudden, the fire was at their front door step.”

For Australia's policy to work in California, residents must be physically and mental trained, said wildfire specialist Max A. Moritz with UC's Division of Agriculture & Natural Resources. In Australia, which conducts formal training,  “there is active participation from homeowners … so both homes and people are better prepared.”

Unprecedented Study Discovers what Urban Coyotes Really Eat

(Care2) Laura Goldman, March 30

Hiking boots, avocados, candy wrappers and fast-food containers. These aren't a few of my favorite things, but they are some of the items found inside the stomachs of dead urban coyotes in Los Angeles and Orange counties.

Since the study began over a year ago, the researchers, led by Dr. Niamh Quinn, the human-wildlife interactions advisor for the University of California Cooperative Extension, have discovered that cats make up only about eight percent of a coyote's diet.

Red blotch grape virus confirmed in Calaveras

(Calaveras Enterprise) Jason Cowan, March 29

Red blotch virus, a DNA infection that decreases a grape's sugar levels on the vine, has been confirmed in Calaveras County, officials said last week.

After confirmed cases of the virus were located recently in El Dorado and Amador county vineyards, University of California Cooperative Extension Farm Adviser Lynn Wunderlich saw what she thought were symptoms of the virus in Calaveras and recommended farmers test for red blotch.

The results came back positive.

Raising chickens at home? Get their eggs tested for free

(Daily Democrat) ANR News release

Californians who raise poultry outdoors are invited to get their eggs tested for contaminants.

To find out if harmful substances on the ground that are eaten by hens get passed along in the eggs they lay, Maurice Pitesky, UC Cooperative Extension poultry specialist at the UC Davis School of Veterinary Medicine, is providing free egg testing.

“We're trying to understand the connection between the environment that backyard poultry are raised in and the eggs they are producing,” Pitesky said.

Here's what trade tariffs could mean in Merced County, where nuts are big business

(Merced Sun-Star) Thaddeus Miller, March 28

China has threatened retaliatory tariffs on a select group of exports from the U.S. following President Donald Trump's plan to impose tariffs on steel and aluminum imports.

China's tariffs would first hit U.S. products such as avocados and nuts, with 15 percent duties. Beijing, if officials deemed it worthwhile, could also place 25 percent tariffs on American-made goods such as pork and aluminum.

…"It doesn't really matter which one it is, whether it's alfalfa, almonds or wherever it may go," said David Doll, a farm adviser with the Merced County UC Cooperative Extension. "They're as much political as they are anything else."

Nuts are big business in Merced County, where almonds are the second largest commodity at $578.5 million, according to the 2016 Merced County Crop Report, the most recent available. Almonds, pecans and pistachios bring in tens of millions of dollars more.

Out of every dollar made on a farm in the Central San Joaquin Valley, half pays for salaries and 40 cents goes to pay for supplies, Doll said, citing UC cooperative studies.

"Farms are businesses, and if they aren't profitable they're not going to stay in business," Doll said.

Scientists say regulation stifles many new biotech traits

(Agri-Pulse) Jim Weber, March 28

Federal regulation of agricultural biotechnology needs to be based on risk and not on process, a wide range of scientists and food industry executives agreed at the Agri-PulseAg and Food Policy Summit. Coincidentally, a similar message was delivered a day later by a Council on Agricultural Science and Technology (CAST) task force.

“Scientists have been screaming that for 30 years,” said Alison Van Eenennaam, a cooperative extension specialist in animal genomics and biotechnology at the University of California-Davis. “That's where regulation should be.”

…Although the USDA, universities and small businesses have developed dozens of GE crops – with improved traits ranging from healthier and less allergenic to safer and more environmentally sustainable – and carried many through safety and pre-market testing, almost all have been denied commercial release mainly because of U.S. regulatory obstacles,” according to the CAST task force, led by Alan McHughen, who chairs the Department of Botany and Plant Sciences at California-Riverside.

If China Strikes Back On Tariffs, California Tree Nut Exports Could Take A Hit

(CapRadio) Julia Mitric, March 27

California agriculture could find itself caught in the middle of the U.S. — China trade dispute.

After President Trump ordered a 25 percent tariff on imported steel and a 10 percent tariff on imported aluminum last week, China hit back, announcing it may impose a 15 percent tariff on agricultural exports from the U.S. 

The U.S. faces competitors for every agricultural product it exports. California wines, for example, compete with wines from New Zealand and Chile. If China hits the U.S. with a 15 percent tariff on wine, that's a problem, explains Dan Sumner, Director of the University of California Agricultural Issues Center.

"We may think California wine is special, but not everybody does,” Sumner said. "And if it's 15 percent more expensive than it used to be because of the tariff, there'll be a substantial reduction in how much gets sold in China."

Building an IPM Program to Fight Fruit Flies

(Growing Produce) David Eddy, March 26

When faced with spotted wing drosophila (SWD), it's critical for growers to keep in mind this is almost certainly unlike any pest they have dealt with before. That's because it's one of two species — out of a potential 1,500-plus — that feeds on healthy, not rotting, fruit.

That's certainly not the end of growers' difficulties with SWD, says Jhalendra Rijal, University of California Cooperative Extension Area IPM Advisor, Northern San Joaquin Valley. It's tricky because vinegar flies — the tiny flies often found circling above fruit bowls on kitchen tables — are so ubiquitous. Even the oh-so-common name, “fruit flies,” indicates the pests' omnipresence.

Stallion Springs 4-H Swine Group visits local swine breeder

(Tehachapi News) Olivia Loyd, March 24

Tim Sturm, owner and operator of California Swine Services, farrowed approximately 600 piglets this year which will be shown all over California by 4-H and FFA members who take them to fairs and jackpot shows.

Sturm, who has a passion for teaching today's youth about raising swine, allowed the members of the Stallion Springs 4-H swine group to come to his facility on March 17 to learn to process one-day-old piglets. The kids learned to ear notch, dock tails, administer shots and clip needle teeth. Members learned why these processes are necessary, how to do them cleanly and correctly, and last were actually able take part in the process. They also learned valuable information about pig breeding and husbandry.

Small Farms Must Include Marketing

(Cal Ag Today) Jessica Theisman, March 22

Mark Gaskell is with the University of California cooperative extension as a small farm and Specialty Crop Advisor for San Luis Obispo County. Gaskell recently told California Ag Today about his work with growers and small farms in the county since 1995.

“Part of my job has to do with applied research and educational programs, and this case related to keeping small farms viable and successful,” Gaskell said. “These activities include troubleshooting problems, helping growers develop new crops and develop new market opportunities that make them more competitive.”

How Biocontrols Fit into a Traditional Pest Control Program

(Growing Produce) Carol Miller, March 21

One of the great strengths of using biocontrols is that it allows growers to use traditional chemistries less often, says Surendra Dara, Strawberry and Vegetable Crop Advisor with the University of California Cooperative Extension. Dara was speaking to a packed room at the Biocontrols USA West conference in Carlsbad, CA, hosted by Meister Media Worldwide, the parent company of American Vegetable Grower.

Has the California dairy industry gone sour?

(Agri-Pulse) Tyler Ash, March 21 (Subscription only)

Rumors are circulating that a stampede of California dairy producers is heading toward greener pastures in other states. But why?

Experts in the nation's No. 1 milk-producing state have been ruminating on this dilemma for over a decade now, and it seems to stem from the same problems that are plaguing farmers all over America. Typical of the ag industry in general, mom-and-pop farms are going by the wayside and more large-scale farms are increasing production. So, the production seems to truck along but the number of players in that production does not.

“I remember being a kid, driving up I-5 and there were dairies all over the darn place,” said Jeff Stackhouse, livestock adviser for the University of California Cooperative Extension in Humboldt and Del Norte counties. “Now there's one.”

Statistics from the California Department of Food and Agriculture back him up. According to the agency, the state had 1,563 dairies in 2012 and four years later the number was 1,392, an 11 percent decline. The drop was 4 percent from 2015.

...Frank Mitloehner, professor of Animal Science at UC-Davis and a UC Cooperative Extension specialist, said California has lost approximately one fourth of its dairies over the last 15 years. His research focuses primarily on air quality related to livestock production and specified that the number of dairy cows in California hasn't actually decreased, just the number of dairies. He confirmed that most of the dairies that have closed were relatively small and weren't as competitive in today's market.

“The small ones often have a harder time in a strongly regulated environment,” Mitloehner said. “Large dairies generally hire some consultants to deal with air and water regulations to get their dairies to comply, but many small folks lack resources.”

According to Betsy Karle, dairy farm adviser for the University of California's Department of Agriculture and Natural Resources (UC ANR), the primary regulation that significantly affected California dairy producers was the General Order of Waste Discharge Requirement that was implemented by the Regional Water Quality Control Board in 2007, which affected approximately 1,400 dairies in California's Central Valley.

'Buy local' food programs deceive consumers and are rarely enforced, a USA TODAY Network investigation finds

(The Republic) Robert Anglen, March 20

As local-food sales grow into a $20 billion industry, a USA TODAY Network investigation found that state-branding programs designed to inform consumers and support local farmers are deceptive and virtually unregulated.

These "buy local" programs purport to connect shoppers with food from their states by affixing logos and stickers.

…"The word local is chic; it sells things," said Cindy Fake, horticulture and small-farms adviser for the University of California Cooperative Extension. "So it's used by everybody and anybody."

Fake said the word "local" has no clear definition and consumers are easily misled.

"They are likely to be deceived," she said. "Consumers are thinking one way and the marketers know that. They know consumers want local, so they say it's local." 

… "There is a huge diversity across states about what is local," said Gail Feenstra, deputy director of the Sustainable Agriculture Research and Education Program at the University of California Division of Agriculture and Natural Resources. 

Feenstra said there is more transparency on fresh produce because it's easier for consumers to identify where it came from and recognize regional products on store shelves. 

But shoppers need to do their research, she said.

Roof Rat Damage Causing Concern for Growers

(AgnetWest) Brian German, March 16

Typically more of a problem in urban areas, roof rat damage is causing significant concern for farmers. According to University of California Agriculture and Natural Resources (UCANR) scientists, roof rats are appearing in considerable numbers this year.  Researchers suggest monitoring fields for rodent activity and using bait stations before the growing season to prevent problems from developing further.

Valley farmers welcome rainstorms

(KFSN-TV) Reuben Contreras, March 15

Rain in the valley and snow in the Sierra from the last few weeks is adding to the water supply local farmers count on to grow their crops.

…"During the strawberry season if you have too much rain it is going to cause the fruit to rot," said Michael Yang of the UC Cooperative Extension Fresno County. "So during the full harvest, we don't want any rain."

Yang works with smaller growers in Fresno County. He says almost all of them rely on groundwater and wells to grow Asian specialty crops sold at farmer's markets.

Pedestrian Orchards Will Reduce Injuries

(California Ag Today) Jessica Theisman, March 14

California Ag Today recently spoke with Becky Phene with the University of California out of the Kearney ag center. She's working alongside Kevin Day, UC tree fruit advisor in Tulare County, on development of pedestrian orchards.

"My background is irrigation. I got asked to participate in the pedestrian orchard with Kevin because he wanted to demonstrate multiple technologies that would be beneficial not just now, but in the future,” Phene said.

Day has combined his pedestrian orchard with subsurface drip irrigation. The pedestrian orchards are by design kept short so that there is no usage of ladders. Eliminating the usage of ladders can help prevent on the job accidents.

“The pruning lets the tree grow quickly and fill in as quickly as possible in the first couple of years, and then he develops the shape of the canopy and the shape of the leaders,” Phene said.

Whole orchard recycling has promise for new almond plantings

Western Farm Press) Tim Hearden, March 14

When it comes time to push out old almond orchards, grinding them into the ground will improve soil nutrients for the next planting, a University of California Cooperative Extension researcher has concluded after years of studying the practice.

Whole orchard recycling increases soil organic matter and carbon, soil nutrients, and microbial diversity, leading to better productivity for the new trees planted in the old orchard's place, says Brent Holtz, pomology farm advisor in the UCCE office at Stockton, Calif.

California Almonds Are Back After Four Years of Brutal Drought

(Bloomberg) Alan Bjerga, Donna Cohen and Cindy Hoffman, March 14

After dropping during the drought, the 2017 almond crop rebounded to a record 2.14 billion pounds of shelled nuts. That's more than triple the amount of walnuts, the No. 2 U.S. nut, and more than four times that of pistachios, which are emerging as a serious competitor for California acreage. Almonds are “incredibly versatile,” said Daniel Sumner, an economist at the University of California, Davis. “And California is the best place to grow it. Where else can the weather be hot and dry and perfect, but you also have a system where you can bring water from mountains full of snow?” Almond-picking is also highly mechanized, which attracts farmers concerned about migrant-worker labor shortages, and its long history in the state creates a level of expertise competitors can't match, he said.

The What, When, and Why of Using Microbials on Your Farm

(Growing Produce) Robin Siktberg, March 12

Why should microbial controls be a part of an Integrated Pest Management (IPM) program? The first, and main one, is that research shows that they work. Many microbial products in the market today are backed by trial data that shows when used correctly, microbials can be a very effective way to improve plant health, suppress pest pressure, and improve yields.

“Microbials are very powerful tools,” says Dr. Surendra Dara, Strawberry and Vegetable Crops Advisor at University of California Cooperative Extension. “They have a number of benefits for the grower. Microbial control agents are either very specific (as with some viruses or Bt) or can attack a broad range of pests (as with fungi). They can have multiple modes of action, which prevents development of pest resistance. They are very safe for workers and consumers, and are a sustainable control option.”

Roof rats are invading California farms and destroying fruit, nuts and irrigation lines

(Fresno Bee) Robert Rodriguez, March 12

Roof rats, a common problem for city dwellers, are migrating to California farms and nibbling on everything from avocados to irrigation tubing.

University of California scientists say last year's wet weather created a perfect environment for the quick-breeding rats to flourish.

…"Rodents are everywhere and they are opportunists," said Rachel Long, a University of California, cooperative extension adviser. "They move in from their surrounding urban habitats to take advantage of any food source they can find. And once that food source disappears they search for food elsewhere."

Do Backyard Chickens Need More Rules?

(KQED) Menaka Williams, March 12

…It was easy to welcome another chicken, partly because Oakland's local policies for keeping poultry aren't that restrictive. Roosters aren't allowed, and hens just have to be housed at least 20 feet from any house. That's it. No rules about the number of birds, their coops, slaughter or care. Bare-bones local laws around chickens are really common, says Catherine Brinkley, a veterinarian and urban planner at the University of California, Davis.

Brinkley says these policies tend to focus on limiting nuisances, like early morning cock-a-doodle-dos or eyesore coops — leaving a gap in codes when it comes to health and safety. "They're not at all focused on public health considerations, like [requiring] training for new owners in washing hands and selling eggs, nor do they think about if somebody is hoarding chickens or other awful things that, quite honestly, happen with animal welfare," Brinkley says.

Trade war could spark food fight, California growers fear

Steel and aluminum may be the intended quarry of a trade war that President Trump has said would be "good" for the U.S. economy, but the casualties of the conflict could be food, agricultural economists warn.

No state has more at stake than California, which leads the country in agricultural revenue. Farmers and ranchers in the Golden State are twice as dependent on foreign trade as the country as a whole. World leaders also likely know that Trump enjoyed deep support in rural, agricultural areas, including much of the Central Valley, said Dan Sumner, an economist who directs the Agricultural Issues Center at UC Davis.

Small Farmers in Fresno Hope for Big Moringa Payoff

(KQED) Katrina Schwartz, Jan. 26

The Mouas, along with other Hmong farmers growing moringa, have been working with farm advisers at Fresno County's UC Cooperative Extension to learn how to dry, powder and store their moringa so they can expand into new markets. Most farmers sell it fresh, but most of the health food craze exists around moringa powder, often imported from India.

… “Value-added products are a great way for a small family farm to increase their income,” said Ruth Dahlquist-Willard, a small-farm adviser with the program. Many farmers are accustomed to only selling fresh produce. They plant a diverse set of crops in a small area and sell a little bit of everything. Producing a product that requires the extra step of drying, grinding and storing is a whole new world for many of them.

“I think there's a lot of opportunity there,” Dahlquist-Willard said. She's particularly excited about how a product might bring the younger generation back to their family farms. Kids who have gone off to college for business, marketing or graphic design might see a new kind of future for themselves on the family farm with a product like moringa.

Flooding alfalfa for groundwater recharge

(Morning Ag Clips) Jan. 24

A rigorous field study in two California climate zones has found that alfalfa can tolerate very heavy winter flooding for groundwater recharge. The research was published online Jan. 16 in California Agriculture journal.

The alfalfa research is the latest in a series of projects studying the effects of using land planted with permanent crops – including almond orchards and vineyards – to capture and bank winter storm water. Such projects have great promise but also require collaboration across multiple jurisdictions and agencies. UC Agriculture and Natural Resources vice president Glenda Humiston has made groundwater recharge on working lands and open spaces a division priority and is working with water and land use leaders around the state to facilitate it through policy recommendations and cross-agency collaboration.

Brent Holtz is a UC cooperative extension Pomology Farm Advisor for San Joaquin County. He recently told California Ag Today about how the fungus band canker on almonds is becoming more prevalent in the San Joaquin Valley.

“I've seen a lot more band canker, which is caused by a pathogenic fungus, Botryosphaeria dothidea, and we're seeing it on young orchards, especially in in San Joaquin county," said Holtz.  "We've seen that a lot out in the delta and we've seen it in eastern San Joaquin county where the soils tend to be a little heavier, maybe old dairy ground and richer and we don't really know why."

California Today: 100 Million Dead Trees Prompt Fears of Giant Wildfires

(New York Times) Thomas Fuller, Jan. 19

The more than 100 million trees that died in California after being weakened by drought and insect infestations have transformed large swaths of the Sierra Nevada into browned-out tree cemeteries. In some areas more than 90 percent of trees are dead.

This week a group of scientists warned in the journal BioScience that the dead trees could produce wildfires on a scale and of an intensity that California has never seen.

…“It's something that is going to be much more severe,” said Scott Stephens, a professor of fire science at Berkeley and the lead author of the study. “You could have higher amounts of embers coming into home areas, starting more fires.”

Winter's good time for gopher control in nut crops

(Western Farm Press) Cecelia Parsons, Jan. 17, 2018

Tree nut growers who are plagued by gopher invasions in their orchards need to stick with effective control measures if they want to minimize tree losses.

Pocket gophers are common in most nut production areas, says Joe Connell, University of California Cooperative Extension Farm Advisor Emeritus in Butte County. In the absence of cover crops or weeds, they will gnaw on tree roots and trunks, and the hungry vertebrate pests can even girdle — and kill — older trees. Trees with root damage and girdling will lose production, and will be susceptible to crown gall, which weakens their structural strength.

Bloomington nursery's citrus trees to be destroyed by California agriculture department

(ABC7 KABC) Rob McMillan, Jan. 17, 2018

Roxana Vallejo was 12 years old when her parents opened up Santa Ana Nursery in Bloomington. Wednesday, the California Department of Food and Agriculture will be at her business to destroy almost all of their citrus trees. Vallejo said the combined value of the trees is almost $1 million.

"They're all fine, and look at all the new growth, it's pretty good," Vallejo said.

The reason they're being cut down is huanglongbing, or HLB, one of the world's worst citrus diseases. The insect that spreads HLB has taken a strong foothold in Southern California.

"It's estimated that the citrus industry may go commercially extinct unless they can get a handle on this problem," said Mark Hoddle, UC Cooperative Extension specialist at UC Riverside, more than one year ago.

OPINION: Ranchers give thanks

(Ventura County Star) Beverly Bigger, president of the Ventura County Cattlemen's Association, Jan. 16, 2018

Matthew Shapero
The majority of attention and sympathy have rightly gone toward those who lost their homes in the Thomas Fire, but I would like to take a moment to highlight the story of others who have suffered as well. They are largely invisible, hidden among the hills and canyons, but their contribution to the county is significant.

Ventura County is home to a robust and historic cattle industry, one that makes up a $2 million portion of Ventura County's agricultural sector. Ranchers play an important role in land management as well, their grazing operations clearing overgrown brush, reducing the fuel available to wildfires and protecting nearby communities.

In the space of 12 hours, the Thomas Fire ripped through vital grazing land that cattle rely on for their daily feed. Sadly, some animals were also lost to the fire.

With feed and fencing gone, many ranchers had hard decisions to make regarding the future of their operations, and some were not prepared for this kind of disaster. Thankfully, we have dedicated public servants who stepped up to help the cattle industry.

Ventura County Agricultural Commissioner Henry Gonzales, Matthew Shapero from the UC Cooperative Extension, and Donna Gillesby and Bryan Bray of Ventura County Animal Services all reached out to ask what they could do to help.

An emergency program was put in place to supply five days of hay until ranchers could get on their feet. The UC Extension also provided a one-stop location where ranchers could meet with representatives from multiple agencies to apply for assistance programs.

The assistance of these agencies was very much appreciated. We want to thank and recognize them for helping us in our time of need. We look forward to returning to our passion: managing and improving the land and continuing Ventura County's ranching heritage.

Farm advisor tests strategies for controlling horseweed

(Ag Alert) Bob Johnson, Jan. 10, 2018

One morning last summer, University of California Cooperative Extension vineyard weed control advisor John Roncoroni displayed a horseweed plant that had grown to more than 10 feet tall in a Yolo County vineyard.

Horseweed, which is widely seen on the sides of the state's highways, is among the glyphosate-resistant weed pests that can develop healthy populations in even well managed vineyards.

"We're really having problems with weeds coming in the fall that are resistant to Roundup," Roncoroni said. "Willow herb is tolerant; it's never been completely controlled by glyphosate."

Pomegranate returns not so wonderful but largest grower says otherwise

(Hanford Sentinel) By John Lindt, Jan. 11, 2018

A few years ago Central Valley pomegranate growers appeared to be riding a rising tide of popularity for pomegranates spurring optimism about the crop's future. Growers, including those in Kings County, enjoyed prices of over $1,700 a ton as recently as 2011.

After a significant planting of new trees, by 2015 pomegranate tonnage was fetching just $450 a ton in Fresno County and falling to $362 a ton in Tulare County according to its 2016 crop report.

…UC Farm Adviser Kevin Day says it's simple economics. “We are seeing both overproduction and lack of demand for pomegranates despite expectations to the contrary."

Western Innovator: Promoting sustainable ranching

Tracy Schohr
(Western Farm Press) Tim Hearden, Jan. 9, 2018

Tracy Schohr has devoted much of her career to promoting sustainability in ranching.

While at the California Cattlemen's Association, she put on an annual “rangeland summit” that brought ranchers together with environmental experts and climate change policymakers.

She also worked on a program to limit ranchers' risk of facing Endangered Species Act violations if they created habitat on their land.

After going back to school to earn her master's degree at the University of California-Davis, Schohr has become a UC Cooperative Extension livestock and natural resources adviser based in Plumas, Sierra and Butte counties. http://www.capitalpress.com/California/20180108/western-innovator-promoting-sustainable-ranching

Building blocks for tending flocks

(Auburn Journal) Julie Miller, Jan. 7, 2018

Counting sheep is no longer for the tired and sleepy.

Shepherding has become a booming industry in Placer County. At last count, there are 9,000 head of sheep registered with the county, said Dan Macon, livestock and natural resources advisor for University of California, for Placer and Nevada counties. And there may be more sheep that have not been registered, perhaps because they are in a smaller flock of 10 to 15, he said.

Sheep have proven to be versatile. Not only raised for the meat and milk, but also wool fibers, plus, they can help reduce fire danger by eating away tall grasses and shrubs.

After a recent outbreak of E.coli, is it safe to eat romaine lettuce? Experts differ

(Fresno Bee) Robert Rodriguez, Jan. 5, 2018

If you are staying away from romaine lettuce because of an outbreak of E.coli, it's understandable. But at least one food safety expert says it may not be necessary.

…But University of California food safety expert Trevor Suslow said it's unlikely the lettuce you buy at the grocery store these days is going to do you any harm. That's because the illnesses happened from Nov. 15 through Dec. 8. Lettuce sold during that period wouldn't be around anymore.

“It's not going to last that long, it's gone,” Suslow said.

Cattle Ranchers Join Conservationists To Save Endangered Species And Rangelands

(Forbes) Diana Hembree, Jan. 5, 2018

…California has a strong incentive to preserve its 18 million acres of ranchland: Cattle and calves are the state's fourth-leading agricultural commodities (milk and cream are No. 1), according to state agricultural data. But in a Duke University survey of the state's ranchers, more than half said they were “more uncertain than ever” that they would be able to continue ranching. California is losing an estimated 20,000 acres of rangeland each year, according to the Nature Conservancy, and on any given day ads for the sale of cattle ranches dot the Internet. The median age of California ranchers is 58 to 62, and more are aging out of the business with no children interested in taking over the ranch.

But this trend can be reversed, according to Lynn Huntsinger a professor of environmental science and rangeland ecology at UC Berkeley. To preserve these landscapes for future generations, ranchers need payment and recognition for their ecosystem services “in order to preserve these working landscapes for future generations,” Huntsinger writes.

Months after Wine Country fires, damaged vineyards face uncertainty

(SF Chronicle) Esther Mobley, Jan. 4

…“No one knows what's the real threshold for heat damage,” says Rhonda Smith, the Sonoma County-based viticulture farm adviser for the University of California, who has come to Gilfillan to consult on its rehabilitation.

Much of the conventional wisdom about how fires interact with vines — that vines can't burn, because of their high water content, for instance — didn't turn out to be true for every vineyard, she says.

“In 99 percent of cases, vines were fire breaks,” says Smith. But if there was dry vegetation, if there was wood mulch on the ground, if the soil was especially dry — if, if, if — then they weren't.

Progress reported on robotic weeders for vegetables

(Ag Alert) Bob Johnson, Jan. 4

The next generation of computer-controlled, automated cultivators will be able to use cameras to remove weeds in the seed line as close as 1 inch from young tomato or lettuce plants, without damaging the crop.

“It must be more than half the lettuce acreage that is already using the automated thinners,” said Steve Fennimore, UC Cooperative Extension vegetable weed specialist.

Fennimore is supervising the Salinas lettuce trials of “marking” the crop in order to make this technology practical for weeding as well.

“The weeders already out there tend to be prototypes that people are still experimenting with,” he said.

2017's natural disasters cost American agriculture over $5 billion

(New Food Economy) Sam Bloch, Jan. 4, 2018

Over a period of 10 months in 2017, America experienced 16 separate, billion-dollar weather and climate-related disasters. Those weather events carved paths of destruction straight through some of the most fertile and productive regions of the country, wreaking havoc on beef cattle ranches in Texas, soaking cotton and rice farms in Louisiana, orange groves in Florida, and burning up vineyards in California. And that was all before Southern California's still-active Thomas fire, which began on December 4, and then closed in on the country's primary avocado farms. It's now the state's largest-ever, in terms of total acreage.

  • Acres of cherimoya trees in Santa Barbara County destroyed by the Thomas fire: 100
  • Total dollar value of Santa Barbara cherimoya fruit damaged by fire: $5,000,000
  • Acres of avocado fields in Santa Barbara and Ventura Counties threatened by wildfire: 5,260
  • Estimated pounds of Hass avocados in Ventura County lost to wildfire: 8,060,000
  • Total dollar value of that lost harvest: $10,175,750
  • Approximate percentage of American avocado crop threatened by wildfire: 8
  • Expected effect of wildfire on avocado prices in America, due to reliance on imports: 0
  • Winegrape acreage in Napa and Sonoma Counties: 104,847
  • As a percentage of total California winegrape acreage: 22
  • Estimated dollar value of unharvested Cabernet grapes in those counties, before the wildfires: $175,000,000
  • Estimated dollar value of those grapes, now tainted by smoke: $29,000,000
  • Bottles of 2016 Napa Cabernet you can buy for the price of two 2017 vintages, due to winegrape scarcity: 3

There Is No “No-Fire” Option in California
(Bay Nature) Zach St. George, Jan. 2, 2018

As the use of prescribed fire by Cal Fire declined in recent decades, its use also declined with private landholders, says Lenya Quinn-Davidson, director of the Northern California Prescribed Fire Council, who leads prescribed burning workshops across the state. Scott Stephens, the UC Berkeley professor, concurs. Decades of suppression left the western U.S. with relatively few people trained to carry out the work: “We just don't have that experience to pass on.” But it's important not to let the current enthusiasm pass, he says—as climate change continues to push conditions toward extremes, as wildfires consume more and more of fire agency budgets, and as the wildland-urban interface expands, it will only become more difficult to bring fire back.

Scientist discusses working on Food Evolution movie

(Brownfield Ag News) Larry Lee, Jan. 1

A scientist involved in a movie about genetically modified food says many don't understand what GM is, let alone the benefits.  Alison VanEenennaam says, “Really, it's a breeding method, and I think the public sector applications for things like disease resistance have very compelling societal benefits that I think most people can relate to.  I don't think we want plants and animals getting sick, and if we can solve that problem genetically rather than using chemicals, I think people get that.”

VanEenennaam is a geneticist at the University of California.  She tells Brownfield there is a lot of unnecessary fear about eating genetically modified food.  “The safety around GM (Genetically Modified) has been established and is, you know, agreed on by every major scientific society in the world and yet we've got the vast majority of consumers that don't believe that.”

Urban Edge farm program offers immersion-style learning

(East Bay Times) Lou Fancher, Jan. 1, 2018

After operating a pilot version of the ambitious program, a $200,000 grant from the USDA National Institute of Food and Agriculture's Beginning Farmer and Rancher Development Program is a launch pad for the immersive learning experience.

For the first cohort of students, many of them women and/or people of color, immigrants, refugees, veterans or farmers-to-be with limited resources, the land is a classroom. Instruction comes from First Generation and experts from the National Center for Appropriate Technology and UC Cooperative Extension. Participation in the program represents opportunity and fulfills dreams the first-time farmers hold of agricultural avocation, economic stability, families, homesteads and permanence.

Tribute to Paul Verdegaal – one of Lodi's “men behind the curtain”

(Lodi Wine blog) Randy Caparoso, Jan. 1, 2018

This coming February 6, 2018, Lodi winegrowers will get together for their 66th Annual LODI GRAPE DAY. They will also mark the occasion with a celebration of the retirement of Paul Verdegaal, who has been working full-time as San Joaquin County's viticulture, bush berry and almond Farm Advisor under the auspices of UCCE (University of California Cooperative Extension) since 1986.

Planet-friendly orchard recycling makes money sense

The numbers are beginning to trickle in confirming UC Cooperative Extension advisor Brent Holtz' hunch. Chipping and returning expired almond orchards into the soil where they grew is not only environmentally sound, it is economically smart. 

(View a three-minute video of the machinery in action at the end of this post.)

A commercial grinder can be used to chip whole almond trees.

After about 20 years, almond orchards' productivity and vigor begin to decline. Most farmers remove the old trees and plant younger, more vigorous replacements to keep up almond production.

In the past, old trees were easily and cheaply disposed of: they were pushed into a pile and set on fire. Air quality regulations have all but eliminated the practice.

At first, grinding the trees and sending the chips to a co-generation plant was a farmer's preferred option. The companies that used biomass for electricity generation paid an acceptable sum – about $600 per acre – for the wood chips, which helped offset the cost of chipping and hauling the trees off the property.

However today, electrical utilities are looking for clean, renewable energy sources like wind and solar. 

“Cogeneration plants burn wood biomass, which still releases carbon dioxide and methane into the atmosphere,” Holtz said. “Many are losing contracts and shutting down.”

The modified manure spreader in the background spreads wood chips, while the roto tiller mixes wood chips into the ground.

Holtz sought another cost-effective alternative, and believes incorporating the wood into the orchard floor may be the answer. Although initially expensive, adding $400 per acre to the $600-per-acre cost of chipping the old trees, the organic matter and nutrients released by the woodchips over time appear to boost yield to a level that covers a chunk of the cost.

In preliminary research, Holtz found that almond orchards where old wood was incorporated into the soil were averaging about 1,800 pounds of meat nuts per acre, while the orchard where old trees had been burned averaged 1,600 meat nuts per acre.

“Almonds sell for about $2 to $3 per pound. To have a 200-pound average yield increase per acre, you've made up the cost of incorporating the wood in just one year,” Holtz said. “It would be even more affordable if farmers can sell carbon credits for the biomass that they sequester in the ground.”

Note the size of chipped almond trees compared to the boots on the ground.

Holtz recently demonstrated two approaches for incorporating almond trees into the soil. The first, which was also used in the study eight years ago at the UC Kearney Agricultural Research and Extension Center in Parlier, is a 50-ton rock crusher called the Iron Wolf. It lumbers down the tree row, grinding up whole trees in place, then reverses over the mangled wood to incorporate it into the ground.

“We thought this one-machine process was the answer,” Holtz said.

G & F Ag Services in Ripon, which has made a business of chipping and hauling almond wood to a co-generation plant, conceived another plan. It modified a manure spreader to spray ground-up wood chips across the orchard floor. Holtz worked with Manteca farmer Louie Tallerico to give the new process a spin.

“This required five different machines working together compared to one Iron Wolf. In this process, the trees have to be excavated by an excavator, then hauled to the wood chipper with a front-end loader. The trees have to be fed into the wood chipper, then the wood chips have to be spread on the orchard floor,” Holtz said. “Another machine, a disk or roto tiller, incorporates the chips into the soil.

The five machines combined are a tremendous time saver.

“The Iron Wolf could do about two acres per day,” Holtz said. “This process can do 15 or 20 acres per day.”

Farmers and industry professionals gather at a UC Cooperative Extension field day at the Tellarico Farm in Manteca, Calif.

Tallerico opened his farm for a field day in October to demonstrate parts of the process to other farmers and industry representatives. Participants stood on layer of fresh-cut wood chip mulch where a full-grown almond orchard stood just weeks before. The spreader demonstrated the ease with which the wood chips are dispersed evenly across the orchard floor, and a tiller mixed the wood chips into the soil.

The Tellarico orchard will now be the site of research – funded by the California Almond Board – to be conducted by Holtz and a team of scientists interested in documenting the growth and development of the new almond orchard among the remnants of its predecessor.

“In the previous study, three years after incorporating the old trees into the soil we started to see the nutrient benefit,” Holtz said. “This was done at Kearney, where we incorporated a peach orchard that had about 30 tons of organic matter per acre. Almond trees are larger, so here we have 86 tons of organic matter being returned to the soil.”

In the new study, the scientists will determine whether the nutrient benefits found in early research still hold true, whether the wood chips in the soil stunt the new orchard or boost its growth, whether the new orchard suffers from replant disease, and the fate of good and bad nematodes (tiny soil-borne worms) in the new orchard.

“We will also study the carbon budget and continue the life cycle assessment of almond with this practice, to better understand the benefit of these processes,” Holtz said.
