Biodiversity and the Natural Suppression of Human Pathogens

Restoring livestock to mixed-vegetable farms allows on-farm fertilizer production and the sale of high-value meat products.  Likewise, diversifying farms with native plants provides habitat for pest-killing birds and predatory insects. Unfortunately, both practices carry the risk of unintentional contamination of produce by human pathogens (e.g., E. coli O157:H7), transmitted through livestock feces or those of […]

Introducing Organic Quinoa Production Systems in the Palouse

The popularity of quinoa in the past decade has quadrupled prices at U.S. retail outlets. For all this demand, the vast majority of the quinoa consumed in the U.S. is imported from Peru, Bolivia, and Ecuador, with 65% of the quinoa sold in the U.S. being organic. This project hopes to increase organic quinoa production […]

Sustainable methods of nitrogen (N) fertility and weed management in organic production systems remain a challenge. Composted animal manures are commonly used to supply N, but only a fraction is in immediately available forms with the remainder released slowly as a result of microbial driven processes. These amendments come at a high cost, and excess […]
