Abstract
The University of Idaho researchers and extension specialists are collaborating on a state-wide project to support the development and adoption of technologies that transform nutrients in dairy manure into commercial fertilizers and manure-based bioproducts. Updating nutrient management recommendations for Idaho crops (including wheat and barley) and evaluating the long-term effects of nitrogen fertilizers and newly developed manure-based bioproducts on soil carbon, nitrogen, and phosphorus levels plus soil health (e.g., microbial biomass, organic matter content, and soil carbon content) are among the key objectives.
