Standing in front of a field of strawberries, a research associate shows a Central Coast grower data in the CropManage app on his mobile phone.

Results from a nutrient management practices study conducted by UC Riverside and @ucanr.edu @ucanrwater.bsky.social scientists show that most growers are adopting four or more practices in the same field. For details, see doi.org/10.3733/001c...

Adoption patterns of on-farm nutrient management practices and nitrogen application rates in California’s Central Valley #cawater mavensnotebook.com/2025/10/15/c...

Many growers adopt multiple fertilization practices, with 26% of fields using six practices and 24% using five, found @ucanrwater.bsky.social researchers. Such bundling may provide growers with more flexibility in managing nitrogen applications. Details in @calagucanr.bsky.social

The Confluence

California communities face emerging contaminants & aging water systems. CIWR’s Blog "The Confluence" shares research by Hope Hauptman on Point-of-use filters and Almond shell biochar. Follow our blog 👉 ucanr.edu/blog/conflue... to learn more about water in California! 🧐

Multiple new fires popping up in California today as heatwave continues to build. Most concerning fire at the moment is the #PickettFire in Napa County near Calistoga. Amid 100+ degree and breezy conditions, it's putting up quite the column, with some local evacs. #CAwx #CAfire

Climate scientist explains what made the Texas floods so extreme As rescuers in Texas search for survivors of the deadly flooding, CBS News is learning the worst-hit areas saw 12 inches of rain per hour in the early morning of July 4. For more on why this storm was...

What made Texas floods so extreme?
"There was a confluence of multiple factors that came together to make this event as intense and as devastating as it was," Daniel Swain @weatherwest.bsky.social @ucanr.bsky.social told @cbsnews.com.web.brid.gy

Meager snowpack adds to Colorado River's woes, straining flows to Southern California Melting snow from California's Sierra Nevada is filling reservoirs. But dry conditions have shrunk the flow of the Colorado River, straining a vital supply for Southern California.

Along the Colorado River, a very dry spring has shrunk the amount of runoff streaming into reservoirs. The latest forecast shows the river’s flows into Lake Powell will probably be about 46% of average. "It’s going to make things worse." @weatherwest.bsky.social www.latimes.com/environment/...

If this is true & it sticks, it would be a costly and deep reduction in federal capacity to support private and public water and flood problems. HEC perhaps the most useful & important water organizations in the world. Visiting foreigners are amazed that such a small group has such global impact.

Like @weatherwest.bsky.social, I’ve managed to forge a career in this space - including with the same institution @ucanrwater.bsky.social - but it has been/is WAY harder than it should be considering the need.

Climate researchers need support to become scientist-communicators Scientific institutions must create roles so that researchers can provide the deep public engagement necessary to respond effectively to the escalating impacts of climate change.

Scientific institutions must create--and sustain--new kinds of roles so that researchers can provide the deep public engagement necessary to respond effectively to the escalating impacts of #climate change. The status quo isn't working. nature.com/articles/d41...
