The October 30 issue of the Sacramento Bee op-ed included an article on soil health by Jeff Mitchell and Randy Southard.
An Op-Ed article written by Jeff Mitchell, CE Cropping Systems Specialist in vegetable cropping systems, irrigation management, soil quality, organic soil amendments, extension models, and postharvest physiology in the Department of Land, Air and Water Resources at UC Davis and at UC ANR Kearney Agricultural Research and Extension Center and Randy Southard, Professor and Soil Genesis/Morphologist in the Department of Land, Air and Water Resources at UC Davis was included in the October 30 issue of the Sacramento Bee. More information on conservation tillage practices can be found on the Conservation Agriculture Systems Innovation (CASI) website.

If you are interested in getting information regarding research on the use of sorghum as a multi-purpose low-input crop for California, please go to this link. Under the research link, there are some videos showing the harvest of experimental plots as well as the use of a drone to perform rapid, robotic phenotyping of sorghum for character traits such as plant height, leaf area, and biomass area--data points used to help search for genes that control mechanisms involved in both drought tolerance and salinity tolerance in sorghum. Research is currently being performed at Kearney Agricultural Research and Extension Center, Desert Research and Extension Center, and West Side Research and Extension Center.
Kearney is participating in a $12.3M study of crop drought tolerance funded by the US Department of Energy. The five-year project is called Epigenetic Control of Drought Response in Sorghum, or EPICON. Peggy Lemaux, cooperative extension specialist at UC Berkeley's Department of Plant and Microbial Biology, is heading the entire project. Co-investigators are Devin Coleman-Derr, Elizabeth Purdom and John Taylor from UC Berkeley; Jeffrey Dahlberg and Robert Hutmacher from UC Agriculture and Natural Resources; Chia-Lin Wei from the DOE Joint Genome Institute; and Christer Jansson from the Pacific Northwest National Laboratory.
Sorghum will be studied to explore the epigenetic mechanisms that allow a crop to survive drought conditions. Epigenetic modifications turn genes on or off without modifying the DNA sequence.
“Historically, the genetic manipulation of crops, which has been critical to increasing agricultural productivity, has concentrated on altering the plant's genetic sequence, encoded in its DNA,” said Lemaux. “However, recent studies have shown that environmental stresses – in our case drought – can lead to epigenetic changes in a plant's genetic information. Because epigenetic changes occur without altering the underlying DNA sequence, they allow plants to respond to a changing environment more quickly.”

The severe California drought--we're in the fourth year--is affecting us all, but it's also...
In their capacity as California Agriculture Systems Innovation members, Jeff Mitchell, Cooperative Extension cropping systems specialist at the UC ANR Kearney Agricultural Research & Extension Center and in the Department of Plant Sciences at UC Davis specializing in vegetable cropping systems, irrigation management, soil quality, organic soil amendments, extension models, and postharvest physiology and innovative conservation agriculture farmer John Diener of Red Rock Ranch in Five Points, CA were part of a panel organized by the Berkeley Food Institute that discussed "farming practices to reduce risks tied to drought."
