Steam: Sustainable management for weeds, soil pests

SALINAS, Calif. -- Steam treatment of soil offers growers a viable alternative to chemicals and a money-saver for organic farmers. It also benefits farm laborers by reducing their exposure to potential harm, said graduate student Erika Escalona. She is assessing the impacts on weeds, soil-borne disease and the soil biome of steam treatments used to disinfest lettuce and spinach fields in the Salinas Valley. 

UC ANR names Roche “outstanding” academic

Leslie Roche has received the Outstanding New Academic Award from University of California Agricultural and Natural Resources. Roche is an associate professor of Cooperative Extension, based in the Department of Plant Sciences. Her research looks at the agricultural, environmental and social aspects of ranching and livestock production.

Linquist named SSSA fellow

 

For many years, agronomist Bruce Linquist has been studying and sharing the benefits of cultivation techniques that reduce water use and farmers’ expenses in the water-intensive crop of rice. Now, the Soil Science Society of America has recognized Linquist’s leadership and research excellence, naming him a fellow of the society.

Miller Award supports careers in Cooperative Extension

Four students connected to the UC Davis Department of Plant Science have received grants from the Milton D. and Mary M. Miller Plant Science Award, which supports learners interested in careers with Cooperative Extension.

The 2024 awardees are Maya Shydlowski, Erika Escalona, Sam Dudley and Ben Baldi. All four students said they are eager to share what they are learning with people in the field who need solutions for everyday problems.

Diagnosing herbicide problems takes detective work

 

A grower applies an herbicide to his tomato plants, or thinks a neighbor’s treatment is drifting over her almond trees. A short time later, the leaves start to bleach or shrivel. Was it the herbicide? Or maybe water stress? Soil nutrients? Perhaps an insect?

Figuring out the causes of crop problems takes detective work, and like solving any mystery, it starts with knowing the signs, gathering evidence and asking questions.

Alfalfa: Flexible amid drought and high in protein

As growers face continued reductions in water available to irrigate crops, and while the world needs more food produced and more protein in particular, alfalfa offers an attractive option. It yields remarkedly well under reduced irrigation, and its protein can be consumed by both animals and people.

Green waste byproducts work as fertilizer, could save farmers money

Anaerobic digesters are commercial facilities that break down food and yard waste to create energy by capturing methane, a potent greenhouse gas. But even this process creates waste of its own. A new study shows some of that secondary waste can be used as fertilizer, potentially saving farmers the cost of chemical fertilizer, a UC Davis scientist explains at a recent field day event.
