In order to slow global climate change and achieve greater energy independence, Americans are showing an increasing interest in switching over to clean, renewable fuels made from home-grown crops. In fact, Congress has mandated that at least 16 billion gallons of cellulosic ethanol be added to the U.S. fuel supply by 2022.
However, estimates suggest that growing crops to produce that much biofuel would require 40 to 50 million acres of land, an area roughly equivalent in size to the entire state of Nebraska.
“If we convert cropland that now produces food into fuel production, what will that do to our food supply?” asks Maggi Kelly, UC Cooperative Extension...

When you think of “amber waves of grain,” do you think of wheat?
You should. It's not only part of “America, the Beautiful,” (lyrics penned in 1893 by Wellesley College professor Katharine Lee Bates), but it's part of California's agricultural landscape.
California annually grows about 800,000 acres of wheat, with about half used for human consumption and the rest for animal feed. It's a highly sustainable rotational crop.
Wheat growers seed the crop in the fall and winter, and harvest it in late spring or early summer. That's when we see the “amber waves of grain.” In the winter, weather conditions permitting, it's emerald green.
Since this cereal crop relies heavily on...

The insecticide chlorpyrifos is a critically important tool for California producers of alfalfa, almonds, citrus and cotton, according to a comprehensive report coordinated by the UC Statewide Integrated Pest Management Program. As part of an action plan, the report identifies specific research, extension and policy gaps that should be addressed to ensure safe, effective use of the insecticide.
The report, Identifying and Managing Critical Uses of Chlorpyrifos in Alfalfa, Almonds, Citrus and Cotton, was commissioned by the California Department of Pesticide Regulation (CDPR) earlier this year and...

Hike off-trail through most any part of the Sierra Nevada and you may find yourself losing your hat to a low hanging branch, your shoe to a thicket of dead and dying brush, or your companion to the crevice hidden by the wall of young trees.
There is no doubt that the forests of the Sierra Nevada, while amazingly beautiful, have grown dense with vegetation. Consequently, forests have become increasingly susceptible to high severity fires, which negatively impact the forest's overall health and our ability to enjoy it.
There is a relationship between a healthy forest and its density. The denser the forest, the more competition individual trees have for valuable resources, such as water, light and nutrients. The effects of...

Beginning in November, a free, drought-focused soil nutrient management series for farmers will be hosted online by the University of California Sustainable Agriculture Research & Education Program (UC SAREP), FarmsReach and Sustainable Conservation.
“Farmers and ranchers have to continually adapt their management of soil nutrients to changing conditions,” said Aubrey White, UC SAREP's communication coordinator. “Adaptation during this extreme drought presents a new challenge for growers and researchers alike. This forum dedicated to the issues farmers will face next season is an opportunity to share resources, research and...
