Variable rate nitrogen: What farmers should know

University of Minnesota Extension’s two-day field School for Ag Professionals is coming up July 29 and July 30, 2026. If you’re an agronomist, a retailer, dealer or consultant, if you’re a summer field scout - we encourage you to attend these small-group, hands-on sessions led in the field by experienced instructors. 12 Certified Crop Advisor CEUs credits are available! For all the details, including info on lodging, visit z.umn.edu/AgFieldSchool2026Today we’re talking all about variable rate nitrogen. What underlying information do we need to make decisions about VRN? What areas in the field might be prone to N loss? Should you only add extra N to high-yielding areas, or could a low-yielding zone also show positive responses? What effect could your overall management strategy have on a variable rate response? All this and more on today's episode.Guests:Brad Carlson, Extension educator (Mankato)Dan Kaiser, Extension nutrient management specialist (St. Paul)Additional resources:Variable rate nitrogen and nitrogen advisory tools: Do they work?Nitrogen SmartUnderstanding nitrogen in soils---Click here to listen to all Advancing Nitrogen Smart podcast episodes.For the latest nutrient management information, subscribe to the Nutrient Management Podcast.
