UMN Extension Nutrient Management Podcast

In this episode, Fabian Fernandez, Dan Kaiser and Jeff Vetch discuss sulfur. What does the research say about fall versus spring application? What is the best source of sulfur for corn? Should farmers be concerned about an interaction between nitrogen and sulfur? Thank you to the Minnesota Agricultural Fertilizer Research and Education Council (AFREC) for their support of this podcast.

Fabian Fernandez, Dan Kaiser and Carl Rosen bust myths around soil fertility. Does variable rate application of fertilizer increase crop yield? Is anhydrous ammonia bad for soil microbes? Listen and learn. Thank you to the Minnesota Agricultural Fertilizer Research and Education Council (AFREC) for their support of this podcast.

Anne Nelson, Brad Carlson and Dan Kaiser talk through on-farm research: what makes a good trial, what to do with your data, what makes for good reporting and some snafus they've seen along the way. If you're considering on-farm trials for spring, listen to this first.

On this episode of the podcast, Dan Kaiser, Paulo Pagliari and Melissa Wilson share considerations for taking representative soil samples, outside factors that can affect results, options for testing and applying to the farm. Hear how this affects decision making with manure and fertilizer in the 2018 growing season.

Daniel Kaiser, Fabian Fernandez, Chryseis Modderman and Melissa Wilson talk about current conditions and what you should be thinking about for fall fertilizer and manure applications.

Guests Brad Carlson, Fabian Fernandez, Dan Kaiser, Greg Klinger and Anne Struffert are here with a spring nitrogen outlook. On this episode, we answer some of your most frequently asked questions, including: How much N should I apply this spring?If I applied N in the fall, how much have I lost going into spring?What about starter fertilizers? How much N should I apply as starter?Is a preplant soil N test worth it this year?Should I use a nitrification inhibitor?What should I do about anhydrous if soil is too wet?For more the latest on nutrient management, follow us on facebook at facebook.com/UMNNutrientMgmt or Twitter at twitter.com/UMNNutrientMgmt.

Carl Rosen, Brad Carlson, Fabian Ferndandez and Dan Kaiser talk cation exchange capacity on this episode of the podcast. We cover the basics of CEC, how it's measured and why it's important. Then, we dive into links between CEC, base saturation and nitrogen and potassium management.

Dan Kaiser, Jeff Vetsch and Fabian Fernandez talk through how weather and management factors may be affecting late season nutrient deficiency symptoms. We talk through how to manage deficiencies at this point in the season, the status of fields across the state, and what to consider before making fall application decisions.

Ryan Miller, Brad Carlson, Fabian Fernandez and Dan Kaiser look at where we are with nutrient management this season. We talk about how the weather has affected N loss, whether you should consider sidedress or variable rate technologies, and how this will impact growers plans in future years.
