In this episode, Tony Mensing sits down with Dr. Matt Helmers to explore the Iowa Nutrient Reduction Strategy (INRS)—an initiative launched in 2013 to reduce nitrogen and phosphorus runoff into the Mississippi River and Gulf of Mexico by 45%. Dr. Helmers breaks down the science and policy behind the strategy, highlighting the roles of both agricultural (non-point) and municipal/industrial (point) sources.  Tune in to hear how Iowa is measuring success against historical baselines (1980–1996), and what’s next in scaling up implementation to meet ambitious water quality goals.
