A Fulbright to France... Congratulations to UC Davis entomology professor Diane Ullman who has just a received Fulbright to research plant virus-insect interactions in France. She will be studying plant viruses and the insects that transmit them. Her sabbatical, to begin in November, will take...
A population of 700,000 horses call California home and many of them live in areas susceptible to wildfire. UC Cooperative Extension forest and fire advisor Kate Wilkin says says landowners can take advantage of equine grazing habits - eating down to the nub - to create a fire safety zone, reported Denise Steffanus in the Paulick Report.
“Having heavy grazing around your structures and then feathering it out as you go farther away from the structures is one way to protect the property,” Wilkin said. “Of course, you want to be careful not to destroy that forage by overgrazing that will cause erosion.”
Just like all rural residents, horse owners should establish a defensible safety zone around structures, including houses, barns, arenas and other outbuildings. Trees should be thinned to create a 15-foot gap between tree tops and shrubbery cleared so it won't ladder fire from the ground to the canopy.
Wilkin said a larger safety zone can serve as an oasis for horses during a wildfire.
“For a lot of fires, if you have an irrigated pasture and you can open the gate so the horses can leave if they need to, they will often be OK,” Wilkin said. “Ultimately, you want it to be a large area … it could be an area about half-mile in diameter, and it needs to be that large to keep the heat from affecting your lungs and your horse's lungs. … You can have trees if they are widely spaced and don't have ‘ladder fuel' around them. Then you can have shade on the property but still be more fire safe.”
Wilkin added that farm owners should not rely on a body of water as a firebreak.
“An ember can travel a mile or more during a wildfire,” she said. “While a creek or a larger body of water can slow a fire down, if there are winds and high temperatures, the fire is still going to cross it.”
So there they were, literally dozens of dragonflies flying around two separate Vacaville (Calif.) yards, feasting on swirling clouds of prey (gnatlike insects) and then touching down on blades of grass or fence posts. They proved as elusive as a celebrities attempting to avoid a...
Nineteen teams of college students from top universities in the U.S., Canada and China will compete to build robots to mechanize farm work at the American Society of Agricultural and Biological Engineers Annual International Meeting in Detroit.
The 2018 ASABE Student Robotics Challenge, being organized by Alireza Pourreza, University of California Cooperative Extension agricultural mechanization specialist, will be held on July 31.
“The labor availability for agriculture is decreasing while the need for more food is increasing to feed the growing world population,” said Pourreza, who is based in the UC Davis Department of Biological and Agricultural Engineering. “So agriculture should switch to technologies that are less labor-dependent, such as using more robots, to overcome this challenge.”
The ASABE Student Robotics Challenge provides an opportunity for undergraduate and graduate students to demonstrate their knowledge and skills of robotics in agriculture.
“The goal of this event is to encourage young agricultural engineers to get involved in building robots for agricultural applications and to get experienced as the next generation of farmers,” Pourreza said.
The challenge will be to simulate the harvest and storage of apples, a crop commercially grown in several states. The students will design and operate robots that will autonomously harvest “apples” on field that measures 8 feet by 8 feet. The robots will harvest eight mature apples (red ping-pong balls), remove and dispose of eight diseased or rotten apples (blue ping-pong balls) and leave eight immature apples (green ping-pong balls) on the tree.
This year, the competitors are being divided into a beginner division and an advanced division.
