That's the key takeaway from a recent paper published by a team that included Leslie Roche, an associate professor of Cooperative Extension in the UC Davis Department of Plant Sciences. The paper describes those challenges, how farmers are confronting them and what should come next.
The Soil Science Society of America has recognized Bruce Linquist’s leadership and research excellence, naming him a fellow of the society. Linquist was among 11 people honored for 2024. He’s a professor of Cooperative Extension in the UC Davis Department of Plant Sciences, with collaborative research projects in the United States, Europe and Asia.
Problems faced by agriculture amid climate change are closely intertwined with non-ag issues. Solutions often have downsides. We have to embrace the complexity, talk to each other, innovate, use technology and be flexible to find solutions that feed us without causing harm to people and while improving and protecting the environment.
Alfalfa expert Charlie Brummer says it's time to "think about redesigning the alfalfa plant from first principles," after 40 years of frustrated efforts to increase yield. He made the remarks at a recent meeting of the North American Alfalfa Improvement Conference. Students also presented their research, including trials to grow the crop with less water.
In the 1990s, long before "regenerative agriculture" was a buzzword and "soil health" became a cause célèbre, a young graduate student named Jeff Mitchell first learned about similar concepts during an agronomy meeting in the Deep South.
Doctoral student Valentina Roel is looking at ways to use food scraps and yard waste as alternatives to nitrogen fertilizer for crops. When processed, the leftovers and garden trimmings being diverted from state landfills might be effective substitutes, because they contain both nitrogen and carbon in forms that promote soil health.
They also provide a path for slowing climate change.
Many farmers have been wary of planting cover crops, despite the proven benefits, because they worry the additional vegetation in their fields and orchards would suck up precious water. But a new video explains recent research showing that’s not true: California fields planted with cover crops over the winter have about the same level of soil moisture.
Dwarfing genes in cereal crops made the Green Revolution of the 1960s possible, but they have limitations. Scientists at UC Davis have discovered a gene that can overcome some of those limitations in wheat by controlling plant height, while boosting yield in fields where water is less plentiful. Their discovery was published today in the Proceedings of the National Academy of Sciences.
The nonprofit organization Pacific Horticulture has released a new video describing research to develop irrigation recommendations for landscape plants, the science behind the process, and early ideas for mindful gardeners and landscapers. It features UC Davis Department of Plant Sciences horticulturalist Lorence Oki, the lead investigator on the project.
New varieties of rice that offer more effective weed control with less herbicide were showcased by UC Davis Department of Plant Sciences researchers at the recent Rice Field Day north of Yuba City in California's Central Valley. Amid the West’s ongoing drought, green rice with heads full of grain stood tall and lush in some test plots, while dry, brown stubble poked up in others. Department researchers discussed the impact of letting ricelands go fallow, including potential for pest control and ways to conserve soil moisture.
