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.

Tony Mensing and Brett Ramirez discuss the importance of preparing swine barns for winter. Key steps include ensuring equipment functionality, particularly fans and heaters, and maintaining a tight barn to prevent air leaks. Regular maintenance and checks are essential for effective winter ventilation.

Fall harvest is here and in this episode we discuss adjusting combine settings, measuring field and harvest losses, and ensuring the safe operation of equipment.

Publications mentioned in the podcast are PM 573: Profitable Soybean Harvesting, PM 574: Profitable Corn Harvesting, and PM 1636: Soybean Harvesting and Drying.

What is biochar and how can we use it to improve the sustainability of animal agriculture? In this episode we sit down with Carly Graves, a graduate research assistant in the Department of Biological and Agricultural Engineering North Carolina State University. Carly recently co-authored of a review paper evaluating the use of biochar to improve the sustainability of animal production and has also studied the use of engineered biochar as a poultry litter amendment. Listen in as we discuss agricultural applications for biochar and ways it can be used to improve agronomic and environmental outcomes. Access the review paper here.
