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.
