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...

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

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

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/...
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.

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.
The focus of this Nature World View piece is not intended to be about me! Instead, the goal is to draw attention to a much broader problem: The reality that deep public engagement by domain experts is not really supported *anywhere*--and that desperately needs to change. [5]
