Grazing livestock may soon be a common sight in the Palouse region of southeastern Washington, usually known for its rolling hills and grain production.
Jonathan Wachter, a soil science doctoral student at Washington State University, has been working with a local farm to improve the competitiveness of organic mixed crop-livestock systems and their potential adoption by growers in a conventional grain-producing region. Read more »

Indigenous people of the Andes Mountains in South America have farmed the nuña bean (a.k.a. “Peruvian Popping bean”) as a staple crop for centuries. Its colorful, nutty-flavored seed is especially prized for its tendency to pop open when roasted—a cooking method that requires less firewood than boiling in fuel-scarce regions.
At the Agricultural Research Service’s Western Regional Plant Introduction Station in Pullman, Washington, plant geneticist Ted Kisha curates an edible dry bean collection that includes 91 accessions of high-altitude nuña beans grown by Andean farmers in Peru, the origin for this legume member of the Phaseolus vulgaris family.

After searching 15 years for a way to combat a devastating disease among salmonids (salmon and trout), researchers at Washington State University (WSU) and the University of Idaho (UI) found an answer inside the fish itself.
Dr. Kenneth Cain’s team at UI’s Aquaculture Research Institute cultured a bacteria from the fish’s gut (designated Enterobacter C6-6) and found that it inhibited the growth of Flavobacterium psychrophilum, the organism that causes Coldwater Disease.
Cain and Dr. Douglas Call, his WSU-based research partner since 2001, found that by adding C6-6 to fish feed as a probiotic they could limit the damage caused by Coldwater Disease – but they’re not quite sure why. “We know that C6-6 produces a toxin,” Call said. “This toxin kills the bacteria although we’re trying to get more funding to figure out how this works in the fish itself.” Read more »

April 22 marks the 45th celebration of Earth Day, with its theme of “It’s our turn to lead.” The U.S. Department of Agriculture’s National Institute of Food and Agriculture (NIFA) is a leader in its support of cutting-edge sustainable and organic agricultural research.
The USDA estimated that 31 percent—or 133 billion pounds—of the 430 billion pounds of the available food supply at the retail and consumer levels in 2010 went uneaten in the United States. It’s not just people throwing away food after “super sizing;” food waste can begin at the farm, where crops are sometimes not harvested because they lack a perfect appearance. Waste also occurs through spoilage or improper cooking.
As bad as this is in terms of not feeding the hungry, wasting food is also wasting energy, water, and everything else required to grow, process, transport, and prepare food. Improving resource efficiency would also decrease the amount of nitrogen released to the environment. Read more »
Participants network at the fourth annual Women in Agriculture – Women, Farms & Food Conference. This year’s theme was “Put Your Best Foot Forward.”
Throughout March, the U.S. Department of Agriculture (USDA) has been highlighting inspiring women in agriculture as part of National Women’s History Month.
Recently, I participated in the fourth annual Women in Agriculture – Women, Farms & Food Conference. This year’s theme was “Put Your Best Foot Forward.” During the one-day virtual gathering, more than 650 women across Alaska, Idaho, Oregon and Washington State were linked via satellite in 28 locations. This enabled women from all walks of life and every sector of the agriculture supply chain to empower one another. Read more »

Clean drinking water for the world is a pretty tall order, considering that the United Nations says nearly a billion people currently go without it. But, that’s exactly the vision that Karen Sorber had when she co-founded Micronic Technologies in 2008 as a family business.
Now a Small Business Innovation and Research (SBIR) grant from the National Institute of Food and Agriculture (NIFA) is bringing the company one step closer to making that dream a reality. Micronic Technologies has introduced “MicroDesal,” a technology that takes well water with unsafe nitrate levels and treats it to the point where the water meets U.S. Environmental Protection Agency clean drinking water safety standards. Nitrates are unsafe for humans – especially children and pregnant women – and livestock. Read more »
