Climate Ready Landscape Plants: $1 million Grant to Expand Program to Western States

June 29, 2020
Research spearheaded by Loren Oki, Department of Plant Sciences, UC Davis, evaluates landscape plants to determine the best low water-use plants for California. Creating water budgets is required by California’s Model Water Efficient Landscape Ordinance. A new grant from CDFA/USDA expands this project to other western states to minimize water use.

Giulia Marino: New Plant Sciences Faculty and Cooperative Extension Specialist

June 22, 2020
Expert on tree physiology in orchard systems

Giulia Marino, a crop physiologist, is the new UC Cooperative Extension (UCCE) Specialist in Orchard Systems, and a faculty member in the Department of Plant Sciences at the University of California, Davis (UC Davis). She is primarily based at the UC Kearney Agricultural Research and Extension Center in Parlier, California, and has a second office in Wickson Hall at UC Davis.

Working Rangelands Wednesdays: Ken Tate, June 3

May 29, 2020
Ken Tate, UC Davis and UC ANR, will address “Water Quality on Pastures and Rangelands” at the Working Rangelands Wednesdays webinar on June 3, 2020. The new series of biweekly webinars focuses on working rangelands in California and the West. Webinars are recorded and offered as podcasts.

Conservation Agriculture Key in Meeting UN Sustainable Development Goals

April 16, 2020
Conservation agriculture is key in meeting UN Sustainable Development Goals. A new analysis shows benefits of conservation agriculture to crop performance, water efficiency, and climate action in South Asia. JK Ladha, an adjunct professor in Plant Sciences, UC Davis, is co-author of the Nature Sustainability article.

Flooding Stunted 2019 Cropland Growing Season, Resulting in More Atmospheric CO2

April 07, 2020
Severe flooding throughout the Midwest — which triggered a delayed growing season for crops in the region — led to a reduction of 100 million metric tons of net carbon uptake during June and July of 2019, according to a new study. Professor Troy Magney, Plant Sciences, UC Davis, co-authored the study.

Research Suggests Water Stress May Benefit Walnut Trees (with video)

April 07, 2020
Portable pressure chambers (“pressure bombs”) taken into orchards measure water pressure in tree leaves, to show how hard a tree works to pull moisture from the soil. This is used to determine when irrigation is actually needed by the trees. Ken Shackel and Bruce Lampinen note that this can benefit yields and orchard health.

Almond Orchard Recycling a Climate-Smart Strategy

April 01, 2020
Recycling trees onsite can sequester carbon, save water and increase crop yields, making it a climate-smart practice for California’s irrigated almond orchards. Professor Amelie Gaudin, Plant Sciences, UC Davis, worked with postdocs, grad students, and Cooperative Extension colleagues.

Cattle Ranchers Cope with Dry Pastures (Video)

March 19, 2020
This winter’s lack of rain, up until mid-March, did not produce much forage for cattle, or carryover vegetation. Leslie Roche, Department of Plant Sciences, covers rangelands and pasturelands, and says this has been commonplace this winter. Many grasses are producing seeds earlier, leading to less vegetative growth.

Effectiveness and Impacts of Dust Control Measures for Owens Lake

February 26, 2020
A new NAS report finds innovative approaches for dust control are needed at Owens Lake, California, to improve air quality, reduce water use, and preserve habitats. Professor Valerie Eviner, Plant Sciences, UC Davis, serves on the Owens Lake Scientific Advisory Panel (OLSAP) to assess how to manage Owens Lake.

CDFA Awards $1.5 Million for Nutrient Management Projects through FREP Grant Program

January 10, 2020
Three from UC Davis — Patrick Brown and Mark Lundy (Plant Sciences) and Thomas Harter (LAWR) — received grants from the CDFA Fertilizer Research and Education Program. Seven recipients received $1.5 million to improve nitrogen efficiency, reduce environmental impacts, and advance best management practices for fertilizer application in farmlands.
