Brad Carlson and Dan Kaiser discuss sidedressing in today's Advancing Nitrogen Smart Podcast episode. What's the big-picture rationale behind sidedressing? How can sidedressing or split-applying be beneficial in terms of avoiding nitrogen loss? Since nitrogen uptake isn't linear, what growth stages coincide with peak daily demand on the crop? Are there any significant risks in starting a sidedress application early in the season? What have past experiments shown regarding positive and / or negative responses to sidedressing? How should inhibitors be used with sidedress / topdress? What should farmers know about soil types and tile drainage when making sidedress decisions? This and much more on the 37th episode of the Advancing Nitrogen Smart podcast series.Guests:Brad Carlson, Extension educator (Mankato)Dan Kaiser, Extension nutrient management specialist (St. Paul)Additional resources:Things to consider when sidedressing nitrogenSplit-applying nitrogen for corn: Three keys for successful sidedress applications (YouTube)What's the right PSNT number?

We're talking all about nitrate management and placement as important factors for reducing nitrogen loss to water on today's episode of the Advancing Nitrogen Smart Podcast series. Different forms of nitrogen have their own potential for loss. How does nitrogen already in the nitrate form differ from ammonium for example? How does basic soil science slow down or speed up nitrogen transformation? Why can't nitrates be easily stabilized in the fall in Minnesota? How do other factors like pH affect nitrogen transformation? This and much more in today's discussion. Guests:Brad Carlson, Extension educator (Mankato)Dan Kaiser, Extension nutrient management specialist (St. Paul)Additional resources:Nitrogen placement: What MN farmers should know about depth, incorporation, loss pathways, and moreHow 4R Nutrient Stewardship can help Minnesota farmersFour things I've learned about nitrogen management for corn based on a decade of research in MinnesotaSix observations from six years of tile sampling for nitrates in southeast MinnesotaNitrogen BMPs and nitrate water quality issues in southeast Minnesota: What should growers be thinking about?--- For the latest nutrient management information, subscribe to the Nutrient Management Podcast.

Brad and Jeff continue their discussion about variable rate nitrogen technology by zeroing in on the pre-sidedress nitrate test (PSNT). What are key differences between the PSNT and the pre-plant nitrate test (PPNT)? What growth stage should the crop reach before taking a PSNT? How have sampling and storage procedures evolved from past years? How variable can samples actually be within the same zone and between zones? What should farmers watch out for when interpreting test results? Do different methods of N application produce different PSNT results? How about timing? Manure? What's N's 'critical value' in Minnesota?

Early April means it's time for the Spring Fertilizer Outlook here on the Nutrient Management Podcast. Our panel of four specialists and researchers begin by discussing current field conditions throughout Minnesota. World events affecting farmers and other ag professionals are top-of-mind right now. How is price volatility impacting input planning - or is it? Should farmers consider changes to their management plans, and /or potentially cut back on specific inputs? If so, which ones and why? Does soil testing become more important during times when other costs are high? As our panelists talk with farmers across Minnesota, what silver linings and bright spots have they noticed in today's ag environment, and why is it important to keep these in mind?

Brad Carlson and Jeff Vetsch talk about variable rate sensors on today's Advancing Nitrogen Smart Podcast episode. What is meant by the term 'active sensors' and what data do active sensors capture? Which specific brands of sensors have the Southern Research and Outreach Center (SROC) researched, and how did they perform? What stage does corn need to reach before sensors can best contribute to variable rate decision making? How do other field variables like soil texture or irrigation systems contribute (or not) to variable rate sensing?

Today on the Nutrient Management Podcast we discuss phosphorus with experts from Minnesota and across the Midwest. Why are Midwest phosphorus guidelines different from state to state? Are Minnesota's current P guidelines satisfactory - or do states' P guidelines need revision? Would a P-rate calculator that incorporates economics be a useful tool, similar to nitrogen's MRTN calculator? What 'Phosphorus & the 4R's' tips and suggestions do our Minnesota, Ohio, Illinois and South Dakota panelists recommend for area farmers?

Today we're going on the road with a conversation recorded during the Minnesota Association of Social and Water Conservation Districts' (MASWCD) annual conference. Mike Schultz, district manager at the Le Sueur County SWCD talks with Brad Carlson about actual methods of incorporating conservation practices into the landscape. What are general categories of conservation practices? How are watershed plans written, and how do they address a balanced set of interests? Which practices tend to appeal to farmers the most?

We return to first principles with a detailed discussion about nitrogen loss on today's Advancing Nitrogen Smart Podcast episode. The five terms that describe how nitrogen is lost from the soil are: leaching, denitrification, volatilization, crop removal and soil erosion & runoff. But what do those terms actually mean? How does nitrogen's chemistry change during loss? Do N loss processes (also called pathways) happen at the same speed? How do temperature and precipitation affect N loss pathways? How might farmers hedge against the risk of loss by incorporating the 4Rs into their N planning?

How variable is nitrogen in one type of manure, and then from type to type? How could changes to a farmer's overall operation affect manure nutrient content? How should manure samples be stored? Safety is huge - what do farmers need to know about staying safe when working with manure? Oh, and how do you prevent sample jars from exploding in the mail? This, and lots of manure info on today's show. Guests:Brad Carlson, Extension educator (Mankato)Melissa Wilson, Extension manure nutrient management specialist (St. Paul)Additional resources:2025 Certified Manure Testing LaboratoriesNitrogen availability of different manure types: What we know and what we are researchingIntroducing ManureDB: A new way to view manure variability and trendsManure managementManure Land Application: Minimum Requirements---Click here to listen to all Advancing Nitrogen Smart podcast episodes.For the latest nutrient management information, subscribe to the Nutrient Management Podcast.
