    25 Years of nutrient management: How have practices changed and evolved?

    Here we are in 2025. Today on the Nutrient Management Podcast, our panelists talk about how the practice of nutrient management has changed over the last quarter century. How have precipitation levels - and perceptions about precipitation - changed? What came before the current Maximum Return To Nitrogen management model, and what did the change address? How has U of M research contributed to sulfur nutrient management understanding? How has awareness of ground and surface water quality evolved? Finally, how has tech changed (or not changed) the practice of fertilizer management over the last quarter century? This and much more on today's show.

    Nitrogen conservation and water quality, Part 1: Tech, edge-of-field, & proactive management solutions

    Nitrogen conservation and water quality are the subject of today's Advancing Nitrogen Smart episode. There's lots to cover so we're splitting the episode up into two parts. Today in Part 1, Brad Carlson and Jeff Vetsch unpack different conservation solutions, and what might be achieved from their adoption. In what situations might buffer strips, cover crops, and corn genetics play their part? What about using technology-such as active and passive sensors? How do any reactive mitigation costs compare with proactive nutrient management planning? This and much more on today's episode.

    Nitrogen conservation and water quality, Part 2: Precision conservation, and future efficiencies

    We continue our conversation about nitrogen conservation and water quality on Advancing Nitrogen Smart. Today in Part 2, Brad Carlson and Jeff Vetsch continue discussing new technologies that may help address nitrogen loss, such as passive sensors and crop modeling systems. How might future tools such as AI play a part? How is precision testing affected by timing? In what ways can hybrid engineering, and further efficiencies in inhibitors be leveraged?

    Soybean nutrient management: IDC concerns, a research wrap-up, and looking ahead to 2025

    Today on the podcast we focus on soybean nutrient management. Our four soybean and nutrient management panelists from across Minnesota and North Dakota explain their research trials, and discuss some preliminary results in the region. Also, what should growers keep in mind as we transition into 2025? What are the panelists' concerns about IDC? That and much more on our last episode of 2024.  Guests: Lindsay Malone, Assistant professor, Climate Smart Approaches to Agriculture (NDSU)Lindsay Pease, Extension nutrient and water management specialist (Crookston)Seth Naeve, Extension soybean agronomist (St. Paul)Daniel Kaiser, Extension nutrient management specialist (St. Paul)Additional Resources: Growing soybeanIs it worth applying sulfur to your soybean crop?Chloride and soybean: What to know about potash fertilizer management— Click here to listen to all Nutrient Management Podcast episodes.

    Predicting nitrogen rates: Factors and resources for Minnesota farmers

    After spending last episode talking about the background and history of nitrogen rate recommendations in Minnesota, today on episode 14 we’re talking about what to keep in mind as you begin predicting your nitrogen rate needs. How do yield, and nitrogen use efficiency (NUE) factor into decision making? Are there any N rate databases available to Minnesota growers? What are the pros and cons of a variable rate strategy, or cover crops for example? Brad and Dan talk about that and much more on today's episode.

  7. Nitrogen loss: Lessons learned from the 2024 growing season

    Nitrogen loss: Lessons learned from the 2024 growing season

    Nitrogen loss: Lessons learned from the 2024 growing season is the big topic on today's episode of the Nutrient Management Podcast. What N application practices looked particularly bad in 2024? Some farmers are saying they are no longer going to apply fall N based on how 2024 played out. Is this warranted, or is it an overreaction? Is there any data back from split-application trials, or evaluations of rescue treatments? What did it tell us? In hindsight, what would have been ideal practices to have used this past year? Moving forward, what can we take away from the 2024 growing season with respect to how to manage fertilizer?

    Nitrification inhibitors in detail: Important information to help delay N loss

    In episode 12 of the Advancing Nitrogen Smart series Brad and Dan talk in detail about nitrification inhibitors. What are the two types of inhibitors, and what are best practices for incorporation? How do soil type, temperature, and precipitation factor into farmer decision-making?
