UC research could help farmers face droughts worldwide

Sorghum is not only a potential drought-tolerant crop for the San Joaquin Valley, it also presents the opportunity for scientists to understand the mechanism behind drought tolerance at the genetic level, said UCCE sorghum specialist Jeff Dahlberg in a segment on ABC 30 Action News.

Reporter Cristina Davies spent an hour and a half at the UC Kearney Agricultural Research and Extension Center in Parlier during the sorghum harvest to learn about the potential of sorghum research. 

"If we can elucidate the genetics behind (drought tolerance), what we believe is we can use those genetics to see if the genetics are available in corn, or in rice, or in wheat," Dahlberg said. "I think the genes may be there. We just don't have the tools yet to search for the genes in those crops."

Conducting drought-tolerance research in California is ideal because the summer is typically devoid of rain. Researchers can control exactly how much water is applied to each sorghum plot. The research has revealed more than 100 genetic markers that may confer drought tolerance.

"We've been really thrilled with the data that's been coming out of this. Like most research, we are learning so many things we don't understand," Dahlberg said.

The research is being conducted in collaboration with the USDA's Agricultural Research Service research center, which is across the street from Kearney. USDA research scientist Devin Coleman-Derr was present for the sorghum harvest.

"Like humans take probiotics, there may be a use for microbes in sort of promoting better and better yields in the field," Coleman-Derr said. 

The 330-acre UC Kearney Agricultural Research and Extension Center is the University of California's largest off-campus agricultural research facility.

Drone technology on display at UC research center

A drone takes a test run over a field at the UC Kearney Research and Extension Center.
The UC Desert Research and Extension Center hosted a workshop for employees and local stakeholders on potential uses for drone technology in agriculture, reported Edwin Delgado in the Imperial Valley Press

“The intent of this workshop is to start bringing the knowledge about unmanned aerial systems to the University of California Agricultural and Natural Resources division and the public at large,” said Sean Hogan, coordinator of Informatics Geographic Information Systems for UC ANR. “There is so much curiosity about it right now, it's a growing industry and there is a lot of concern and controversy about the misuses on it.”

The article said the UC system now has the green light to begin using drones. Hogan is holding workshops throughout the state to share his expertise with UC ANR employees and members of the community.

Desert Research and Extension Center director Jairo Diaz said the workshop was important because participants were able to see a demonstration of how the technology works and how it can be applied to the projects and research they are currently working on.

“These workshops that give growers and stakeholders can use in the area are very important because tech like this can help in the near future help find out different types of issues on the field like management of nutrients, water and find out to improve management of field,” Diaz said.

At the UC Kearney Agricultural Research and Extension Center last week, technicians tested a drone that will be used throughout the summer to collect growth data on 600 varieties of sorghum begin produced under different irrigation regimens. With imaging and lidar, the drone collects information on leaf area and biomass in half an hour that would take a full day for a person in the field.

'Wild and wooly' sheep shearing class held at Hopland

Sheep shearing is hard work, but has rewards.
Many sheep shearing students said the process was "the hardest thing they have ever done," reported Glenda Anderson in the Santa Rosa Press Democrat. The newspaper ran a lengthy feature and a photo gallery of the annual sheep shearing school held at the UC Hopland Research and Extension Center this week.

Reporter Justine Frederiksen of the Ukiah Daily Journal also reported on the sold-out sheep shearing and wool classing training at the 5,300-acre Mendocino County research center.

“And 60 percent of these people had never even touched a sheep before,” said John Harper, UCCE advisor and shearing school leader. Nearly all the students were women and included an artist from San Francisco, a retired fire chief, a UC Davis graduate student, and a woman who was learning to shear ahead of travels to New Zealand “because I think it will be a good skill to have for work, in case I want to stay for a couple of months.”

“One of the things new students have the most trouble with is what we call ‘tipping' the sheep, or flipping them over,” Harper said. He explained that, to get the sheep into the ideal starting position, you need to push its back legs down with one hand and tuck its head in with the other, twisting the animal into a sitting position with all four legs dangling.

UC Hopland REC sheep shearing students are part of a new wave of sheep shearers and wool enthusiasts industry officials hope will reverse decades of disinterest and decline. The shearing classes were booked well ahead of time, said Hannah Bird, a community educator at the research station. Many students are seeking a break from city life or jobs tying them to a desk.

Wrote reporter Glenda Anderson, shearing sheep is sweaty, back-straining work that earns just $2 to $5 per sheep. But an expert sheep shearer taking part in the program said sheep shearing for a living has its benefits.

“It's a lifestyle thing. I could work six months a year and travel around the world,” paying for the travel by working here and there, he said.

Mendocino County no longer to contract with USDA Wildlife Services

Mendocino County supervisors decided to sever ties with the USDA's division of Wildlife Services, reported Peter Fimrite in the San Francisco Chronicle. The decision was made after environmental groups said the agency was indiscriminately killing predators, such as mountain lions and coyotes, because they are a threat to livestock.

The article featured a gallery of 10 artful photos taken at the UC Hopland Research and Extension Center, which maintains a research sheep flock of 500 breeding ewes. Record-keeping of sheep losses to predators began at Hopland in 1973. Coyotes are the most serious predator problem.

Hopland staff use a variety of non-lethal and preventative methods to protect sheep from predators, such as fencing, mob grazing and frequent pasture rotation and guard dogs, according to Kim Rodrigues, the director of the research and extension facility. Currently there are five guard dogs at the center. The guard dogs bond with sheep and protect them primarily by barking and other aggressive behaviors when strangers or predators are near the sheep flock.

Software developer quits job to shear sheep

A five-day sheep shearing school is offered annually at the UC Hopland Research and Extension Center.
A few years after taking a sheep shearing class at the UC Hopland Research and Extension Center, Stephany Wilkes was ready to quit her job at Mozilla and dedicate herself full-time to a shearing sheep in "tiny flocks" around Northern California, reported Tim King in Sheep Magazine, a national publication. (See the link to the article below.)

"This year, I was on a ranch almost every weekend from January through June," Wilke said. "I got pretty burnt out."

With skills honed in three five-day sessions of training at the UC Agriculture and Natural Resources facility in Hopland, she has found she can earn between $50 and $100 per hour shearing sheep.

John Harper, UC ANR Cooperative Extension advisor in Mendocino County, has hosted the sheep shearing school for 20 years and has 40 years experience with sheep shearing. 

"It is the longest running shearing school in California and I believe it's currently the only one,"  Harper said.

The training school started with instructors imported from New Zealand. When the cost of travel became prohibitive, Harper brought in Mike McWilliams from Oregon. Later Gary Vorderbruggen, who trained under McWilliams, became the chief instructor.

The five-day course will be offered again in 2016 with classroom instruction, demonstrations and hands-on experience. Beginning and experienced shearers have the opportunity for one-on-one training. Class dates have not yet been decided. Registration information will be posted on the Sheep Shearing School webpage.
