Nitrogen Use Efficiency and Emissions Hot Topics in Western USA

Western North America Director Dr. Rob Mikkelsen has continued his active partnership with the University of California recently. Due to cutbacks, the University frequently relies on his expertise for educational outreach related to nutrient management.  Dr. Mikkelsen gave a lecture in a graduate plant nutrition class on N use efficiency (please see below). "There is considerable misunderstanding of this term and how to measure it.  We discussed techniques to obtain the maximum benefit from N fertilizer with the students from across the world" said Dr. Mikkelsen.
