UC scientists presented recent additions to the growing body of research on conservation tillage in California at the second annual Twilight Conservation Tillage and Cropping Systems field day last month, demonstrating progress in agricultural systems that will help farmers cut production costs, reduce soil disturbance and save water.
UC scientists and their partner farmers are conducting research that addresses the current needs of the San Joaquin Valley agricultural industry and research that is looking to the future by anticipating changes that may need to be negotiated in coming decades.
During the field day at UC's West Side Research and Extension Center in...

Those of us who work with alfalfa have seen our much-loved Queen of Forages relegated to poster child of all things evil about genetic engineering (GE) and the supposed damage it may wreak. While hay growers have always felt alfalfa has received insufficient attention – this was probably not what they had in mind!
I’m referring, of course, to the release of Roundup Ready alfalfa (RRA) in 2005 and the subsequent lawsuit that stopped its planting from 2007 until 2011 – a case that went all the way to the Supreme Court!
The drama continues today with newly minted lawsuits, as farmers once again plant RRA and conventional alfalfa throughout the U.S. But what does this ballyhoo mean for those who actually grow...

Forget bird watching; next time you spot a hummingbird, listen.
Most of us pause to gaze at the tiny birds’ impressive mid-air hovering, part of their hunting behavior, but males of some hummingbird species generate loud sounds with their tail feathers while courting females.
Now, for the first time, the cause of these sounds has been identified: a paper published in the Sept. 9, 2011, issue of Science reveals that air flowing past the tail feathers of a male hummingbird makes his tail feathers flutter and thereby generate fluttering sounds.

The University of California Cooperative Extension (UCCE) recently co-hosted a field trip with the U.S. Forest Service to view the implementation of a forest fuels reduction project on the Tahoe National Forest.
Over 45 stakeholders, including representatives of state, federal, and local government, industry and environmental groups and local residents attended to see the project, known as the "Last Chance Project," which involves thinning the forest by removing small and medium-sized trees, masticating or mowing down brush, and burning dead material through prescribed fire. The work, being done by Sierra Pacific Industries, under contract to the U.S. Forest Service, should be completed by fall 2012.

If you see a black fly or its eggs and larvae while you're turning over your compost pile, don't be alarmed.
It's probably a "good soldier."
The black soldier fly (Hermetia illucens) is a beneficial insect. And a far-ranging one at that.
Martin Hauser, senior insect biosytemastist at the Plant Pest Diagnostics Branch, California Department of Food and Agriculture, says this is the only Hermetia he can find in the Sacramento region. "If you go south and to Arizona and New Mexico, you'll find more species, which are more colorful."
This New World species, he says, is now worldwide. "I found it in Nepal, Borneo, Australia,...
