Gaudin, Mitchell part of winning team honored for groundwater research

Amelie Gaudin and Jeffrey Mitchell, faculty with the UC Davis Department of Plant Sciences, are part of a team honored for showing growers how wintertime cover crops can improve the soil while having little or no impact on groundwater use.

The team’s research was part of the University of California’s efforts to help growers thrive while complying with state groundwater regulations. Their work was honored with a Distinguished Service Award for Outstanding Team by UC Agriculture and Natural Resources.

UC Davis Research Prepares State’s $3.7 Billion Nursery and Floral Industry for a Drier Future

As California enters a third summer of record drought, farmers who raise nursery and floral crops are looking for ways to grow plants with less water, more efficiently, while fighting new diseases and detecting plagues quicker.

Researchers with the UC Davis Department of Plant Sciences are finding ways to help, with support from the Plant California Alliance. The grower-supported organization has granted nearly $400,000 to the department since 2006, according to college records.

Conservation Agriculture Key in Meeting UN Sustainable Development Goals

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)

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

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.

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

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.

Organic Processing Tomato Production (video #4 of 26)

This video summarizes the production techniques, equipment, and production goals that John and Justin Diener, and Scott Park employ for their organic processing tomato fields. It details the efforts they use to take care of the soil at their farms.
