Abnormal Weather Takes a Toll on California Olive Crop

(Ag Net West) Brian German, May 30

The late winter freeze caused significant issues for several different commodities throughout the state and has been especially problematic for the California olive crop.  The fluctuating temperatures have created substantial concern among the industry as bloom looks to be far below normal levels.

“Overall we're a little on the pessimistic side.  The bloom, on the whole, has been pretty poor, many orchards actually have a very light, to next to no bloom at all,” said Dani Lightle, Cooperative Extension Orchard Systems Advisor for Glenn County.  “There's an orchard here or there that looks pretty good, but on the whole, it is a little bit dismal.”

How Avocados Define LA and the Secret to Making the Best Damn Avocado Toas
t

(LA Taco) Gab Chabran, May 29

…Eric Focht who is a staff research associate in the lab of Mary Lu Arpaia at UC Riverside through UC Agriculture and Natural Resources and the Department of Botany and Plant Sciences tells L.A. Taco that the recent avocado economy boom is “similar to what we see today with something like bitcoin.” He helps run a breeding program at UCR studying different avocados varieties, focusing mostly on Hass avocados but also looking at other less known versions of the popular fruit.

In short, he is working on breeding the perfect avocado that tastes great and is easier, faster, and less water-dependent to grow. This year is shaping out to be a good one for avocados, but this issue is always one to keep in mind.

Focht states that in the future, there will likely be more variety available in the mainstream marketplace. One varietal that Focht gets excited about is the Reed avocado which has now been popping up in places such as Whole Foods. It's known for its round, dinosaur egg shape and is about the size of a softball. It has a relatively large seed but the edible flesh is sometimes double or even triple that of a Haas that can make a lot more people happier per individual fruit.

Amazing graze

(Chico News & Review) Ashiah Scharaga, May 24

When drifting clouds dapple the sky and vibrant wildflowers—tickled pink buds, honey-hued petals and virent stems—awaken in the verdant fields of Table Mountain, explorers quicken their pace. They spot trickling streams and grazing cattle. Occasionally, they look straight down, turning anxious eyes to their mud-slicked heels—did they step in one of the fertile cow-pie mines littered across the landscape?

That may seem a nuisance, but it's a necessity. Tracy Schohr, a livestock and natural resources adviser for University of California Cooperative Extension, said the natural magic of the popular Butte County recreational spot is made possible because of a long-standing grazing program. “If cattle were not actually on Table Mountain Ecological Reserve,” she said, “essentially those invasive species would choke out those native plants, and they wouldn't be there.”

… In the past, grazing was misunderstood and primarily viewed as destructive, said Dave Daley, a fifth-generation Butte County cattleman and associate dean of Chico State's College of Agriculture. He credits changing perspectives to the development of grazing science, fueled by people such as Schohr and Kate Wilkin, a UC Cooperative Extension forestry, fire science and natural resource adviser for Butte, Yuba, Sutter and Nevada counties.

Sheep Shearing 101: Why Aspiring Shavers Flock to This California School

(KQED) Tiffany Camhi, May 23

…“We try to get the students shearing the first day because they make a lot of mistakes,” says John Harper, head of the UC Cooperative Extension Sheep Shearing School in Hopland.

Harper says if you can make the right moves with your feet, everything else falls into place.

“We're dancing instructors,” says Harper. “It's like 'Dancing With The Stars' on steroids, but with sheep.”

Around this time of year, hundreds of thousands of sheep in California need to have their wool shaved off. But Harper says there's a shortage of sheep shearers worldwide.

That's why he started the school in Hopland about 25 years ago.

Dan Macon of the California Wool Growers Association says the growing popularity of backyard flocks in California (usually just a handful of sheep) is adding to the demand for shearers, too.

“Infrastructure of the sheep industry is a key component,” says Macon. “Having people with that kind of skill and willingness to work hard is desperately needed.”

AUDIO: Hey, Salad Lovers: It's OK To Eat Romaine Lettuce Again

(NPR Morning Edition) Allison Aubrey, May 23

…After a big foodborne illness outbreak linked to baby spinach back in 2006, the leafy greens industry put in place a number of procedures to prevent contamination. "Prevention became the major focus after that outbreak," says Michele Jay-Russell, a food safety researcher at the University of California, Davis.

"They set up intensive testing protocols to monitor water quality," Jay-Russell says. The industry also agreed on standardized setbacks — or buffers — to separate growing fields from livestock operations, which can be a source of E.coli contamination. "You want a safe distance from where you're growing fresh produce and where you have concentrations of animals, like on a feedlot or dairy," she says.

Are avocados toast?

(Grist) Nathanael Johnson, May 22

…When Katherine Jarvis-Shean was a doctoral candidate researching the decline of cold winters a few years back, she thought more farmers should be freaking out. “I used to think, ‘Why aren't you guys more worried about this? It's going to be the end of the world.'”

After all, many fruit and nut trees require a good winter chill to bear fruit. But after spending a few years as an extension agent for the University of California — working directly with farmers and translating science into techniques they can apply on the land — she understands better. It comes down to this: Farmers have a ton of concerns, and the climate is just one of them.

“If you decide what to plant based on climate, but then can't make the lease payment, that's not sustainable,” Jarvis-Shean said.

Lanternflies Eat Everything in Sight. The U.S. Is Looking Delicious.

(New York Times) Zach Montague, May 21

…Native to Asia, lanternflies first appeared in Pennsylvania in 2014. Despite a quarantine effort, they have also been discovered in small numbers in New York, Delaware and Virginia.

… “Most pests deposit their eggs on their host plant, or very close, so they already have food available,” said Surendra Dara, an adviser at the University of California Cooperative Extension.

“Those that have the advantage of being able to lay eggs on non-plant material obviously have a better chance of surviving and spreading,” he added.

Garbanzos are catching on in Yolo County

(Woodland Daily Democrat, Ag Alert) Bob Johnson, May 19

…“The largest part of our crop goes to canning, maybe 90 percent,” said Paul Gepts, UC Davis plant sciences professor and legume breeder. “California can only compete with high quality products. We have other varieties with higher yields, but the seeds are too small. The growers get a premium for larger, high quality seeds.”

Gepts developed the two newest UC garbanzo varieties, Vega and Pegasus. Both have large, attractive seeds well suited for the canning market, and both have resistance to Ascochyta blight, a fungal disease that can devastate the crop.

… “I think growers are more interested in garbanzos because it's a winter crop, and wheat prices are low,” said Rachael Long, UC Cooperative Extension farm adviser in Sacramento, Solano and Yolo counties. Long is finishing up UC's first Garbanzo Production Manual, which should be available before the end of the year.

Kale, Not Jail: Urban Farming Nonprofit Helps Ex-Cons Re-enter Society

(New York Times) Patricia Leigh Brown, May 17

Even by the standards of the Bay Area, where sourcing local, organic chicken feed is seen as something of a political act, the spectacle of 30,000 fruit and nut trees being tended by formerly incarcerated orchardists is novel.

…Jennifer Sowerwine, an urban agriculture specialist for the University of California Cooperative Extension at Berkeley, said that Ms. Haleh and Mr. Raders have “shifted the conversation around food justice.”

“It's not just about food security, but the security of providing living wages,” she said. That's no mean feat in a foodie monoculture.

Tough winter weather devastates local cherry, blueberry crops

Machines take over for people at Napa vineyard

(Capital Press) Tim Hearden, May 14

In the heart of the Napa Valley, a vineyard produces fine Cabernet Sauvignon with virtually no help from laborers.

The 40-acre “touchless vineyard” was established by Kaan Kurtural, a University of California Cooperative Extension specialist who has devoted much of his career to improving production efficiency in vineyards as labor shortages have worsened.

…When Kurtural started experimenting with vineyard automation 10 years ago, his primary goal was to save growers money in labor costs, he said. But since then, research has shown that grape quality is superior, largely because the tall canopy protects grapes from sun damage, he said. The system also uses less water than others, he said.

Dozens of strawberry growers gather in Santa Maria to learn latest industry advancements

(KSBY Staff) May 9

More than 100 farmers and growers took park in a meeting teaching them on the best way to grow a healthy strawberry.

The University of California put on the annual event which was free to the public.

Growers discussed improvements handling weeds, disease, and insects.

The Santa Maria Valley is the second largest strawberry growing area in California after the Salinas Valley.

The crop means a lot to people in Santa Maria.

"We've got a number of challenges to the California strawberry industry and we're doing are best to work together," said Steven Fennimore of University of California Cooperative Extension Agriculture and Natural Resources. "I'm optimistic that we'll find some satisfactory solutions."

Growers talked about all kinds of different ways to boost their crop including ways of using images from aircraft to detect stress in plants.

Pesticide Use on California Farms at Near-Record Levels

(Fair Warning) Paul Feldman, May 9

…Some experts say long-term changes in the mix of items farmers produce in California, including increases in almonds and other high value crops, give the agriculture industry the incentive to use more pesticides. Such crops present “a larger economic risk if pests are not controlled,”said Brad Hanson, a weed specialist at the University of California, Davis, plant science department.

Jim Farrar, director of the University of California's statewide integrated pest management program, added that more pesticides are needed when “you move from something like alfalfa and sorghum for dairies, where cosmetic injury isn't a problem … to something like oranges where if there's a blemish on the rind you get downgraded even if the orange is perfectly healthy.”

Cherry growers expect lighter crop yields

(Ag Alert) Ching Lee, May 9,

…Kari Arnold, a University of California Cooperative Extension farm advisor in Stanislaus County, said she's careful not to paint the 2018 cherry season as a disaster year "because it's really not." The crop may not be as robust, she said, but this was somewhat expected, because last year's crop was so big.

What wasn't expected, she said, was the freeze in the spring, which "did cause some damage to flowers." But the damage varied depending on the location of the orchard and whether growers were able to apply frost protection, she added.

"It's still going to be a good crop," she said. "It may not be the same as last year, but they're going to be good cherries. They're probably going to sell at a higher price because there'll be less of them."

She said she's concerned that word of it being a light crop may scare away field help, adding that "it's hard enough to get field labor in the first place anymore, because labor is becoming more and more difficult to come by and more difficult to keep."

Peak Avocado Is Yet to Come

(The Atlantic) Cynthia Graber, Nicola Twilley, May 9

…Its partners in evolution—the giant, elephant-like gomphotheres and three-ton ground sloths that dined on its fruit in return for transporting and then pooping out its giant seed—went extinct soon after the first bipedal apes arrived in the region. Rodents, jaguars, and eventually humans stepped in as dispersal mechanisms, albeit significantly less effective ones. The flourishing avocado forests that carpeted much of Mesoamerica dwindled and died out. And, as Mary Lu Arpaia, who runs the avocado breeding program at the University of California at Riverside, explained, the avocado became a backyard fruit, enjoyed by first the indigenous peoples and later the conquistadors, but rarely cultivated intensively—until recent decades.

More illnesses with later onset dates linked to romaine outbreak

(The Packer) Ashley Nickle, May 8, 2018

Richard Smith, a University of California Cooperative Extension advisor based in Salinas, also said the outbreak is hurting sales.

“It's having an effect,” Smith said May 7. “This is the problem — lettuce is pretty expensive to grow, and you've got to cover your costs. You can lose money, at this point the bigger growers can afford to lose for a period of time, but then they've got to make it up, and it just makes it hard. We're not sure how the year's going to go.

“I guess the good news is that the consumers are being sophisticated enough to be focusing on the romaine (versus all lettuce) ... The reality is I guess the FDA doesn't want to clear romaine yet because they think that the lettuce from Yuma might have a 21-day shelf life, so until the FDA clears it and then that news gets clearly articulated, I think it's going to be a damper.

AEI economists say farmers have ‘beef' with Trump

(Hagstrom Report) May 7, 2018

…Daniel Sumner of the University of California at Davis also told The Hagstrom Report that farmers hurt by the administration's trade policies have "a beef" with Trump.

Sumner said that even though the tariffs on Chinese steel and aluminum have not yet gone into effect, California farmers including wine and almond producers are already worried. "Even if the tariffs don't happen, the rhetoric has effects," he said.

Sumner also said that Mexican buyers of U.S. dairy products — "reasonable business people in Mexico" — began months ago to contact New Zealand dairy producers about becoming a supplier because the Mexicans are worried about the impact of the North American Free Trade Agreement renegotiation.

Egg prices plunge as supplies rebound

(Capital Press) Tim Hearden, May 4

 Commercial egg prices in California are plummeting, and a slow global economy combined with a rebounding chicken flock after last year's devastating avian flu outbreak are among the contributing factors.

…At first, Midwestern egg producers that didn't want to retrofit their barns simply avoided California. Those that did want to market to California found confusion in what actually constituted a Proposition 2-compliant cage, said Joy Mench, a University of California-Davis animal science professor.

“(T)he wording of Prop. 2 does not allow it to be regulated, so there is no official definition of what it means,” Mench said in an email. “That will have to be decided in the courts, either because there is a lawsuit or because someone is prosecuted.”

In enforcing the initiative, the CDFA uses the federal Shell Egg Food Safety rule, whose space requirement is larger than the United Egg Producer guidelines that most of the other states use, noted Maurice Pitesky, a poultry specialist at the UC-Davis School of Veterinary Medicine.

Farming takes center stage at Yolo County Fairgrounds

Woodland Daily Democrat) Cutter Hicks, May 4

Field trips to the fairgrounds led to a farming experience for students as the Yolo County 4-H and Farm Bureau hosted its 10th annual Farm Connection Day to kick off the Spring Show this weekend.

The four-hour event Friday featured more than 100 agricultural displays and hands-on activities for kids of all ages as nearly 2,500 visitors walked through the gates.

Farm Connection Day was open to the public and more than 200 4-H students teamed up to host the event — with a little help from adult volunteers. Their focus was to teach students of Yolo County the aspects of the organization before judging shows later that day.

DeAnn Tenhunfeld, a Farm Connection Day organizer, said that the attendance was the largest seen since she founded it in 2008.

Frost damage varied for California nut trees

(Farm Press) Robyn Rominger, May 2, 2018
Some almond growers experienced frost damage from recent freezing conditions, say University of California experts.

“There's really a lot of damage,” says Katherine Jarvis-Shean, UC Cooperative Extension orchard systems advisor for Sacramento, Solano, and Yolo counties. “The earlier varieties really took a hit. Some trees even dropped their nuts due to frost damage. It's pretty bad in some orchards.”

… Bruce Lampinen, UCCE almond and walnut specialist, measured temperatures in an almond trial at Davis, and notes that “Feb. 20 and 24 were the coldest days. It was very problematic because that's when the trees were in full bloom.” At full bloom, temperatures below 28 degrees F. can cause crop loss.

…Phoebe Gordon, UCCE orchard systems advisor for Madera and Merced counties, says, “From what I've seen and heard, the damage has been variable. Some orchards weren't hit that hard, and others were hit very hard. I think it depended a lot on micro-climate and what stage the trees were in. They become more susceptible to frost damage as they transition from dormant to full bloom, and to nut set. I don't think we'll really know until ‘June drop' is finished what the final load is.” 

Dani Lightle, UCCE orchard systems advisor in Glenn and Butte counties, says, “Almonds were right in the middle of full bloom when the frost happened. Most of the orchards in my area seem to have escaped. We didn't seem to cross the threshold to where there was heavy damage. Of course, there are exceptions, but by and large we came out better in the end than we thought we would.”

New weapon in fight against walnut blight

(Farm Press) Robyn Rominger, May 2, 2018
Walnut growers have a new tool to help manage blight disease in their orchards — Kasumin 2L, manufactured by Arysta LifeScience, is the trade name for kasugamycin, and is available as part of a strategy to control the disease.

The new bactericide was discussed at a recent University of California Cooperative Extension breakfast meeting at Yuba City. “It's great to have another chemistry in the rotational loop for blight management in walnuts,” says Emily Symmes, UCCE integrated pest management advisor.

UCCE advisors promote targeted grazing to reduce wildfire threat

The natural magic of grazing at the Table Mountain Ecological Reserve in Butte County is made possible by running cattle in targeted areas for carefully planned periods of time, reported Ashiah Scharaga in the Chico News & Review.

"If we reduce the amount of vegetation that is there through livestock grazing, we can reduce the amount of fuels that would be available to help a fire spread and carry and build up intensity," said Tracy Schohr, UC Cooperative Extension livestock and natural resources advisor in Butte, Plumas and Sierra counties.

Targeted grazing, Schohr said, also keeps down grasses, weeds and invasive species, serving as an element in the land management "toolbox." 

"If cattle were not actually on Table Mountain Ecological Reserve, essentially those invasive species would choke out those native plants, and they wouldn't be there," Schohr said.

In the past, grazing was considered destructive, however, perspectives have changed with fire science research. One such researcher is Kate Wilkin, the fire science and natural resources advisor for UCCE in Butte, Yuba, Sutter and Nevada counties.

Wilkin said that there has been a long history of grazing in the West, dating to the 1700s. Livestock historically overwhelmed the environment, causing degradation to wetlands and meadows especially. Using animals in a targeted way, however, can reduce fire risk without destroying the natural landscape.

Schohr and Wilkin will host a day-long Irrigated Pasture and Annual Rangeland Management Workshop May 31 at the Chico State University Farm.

 

Targeted cattle grazing can reduce fire risk and help maintain natural resources.

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.

Band Canker Affecting Younger Almonds

(California Ag Today) Patrick Cavanaugh, Jan. 24

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.

(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.
