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.

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.

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.

How to Manage Nitrogen Fertilizer on Rice When It Rains During Planting

May 22, 2019
Rain in May, especially in the amounts we have seen this year, is far from ideal for rice growers. It makes establishing seedlings, nitrogen management, and weed control extra challenging. Here are three scenarios and some ideas on how to best manage nitrogen fertilizer.
