    Episode 35: Drainage Research
    (2021-02-24) McDivitt, Paul; Carlson, Brad; Fernandez, Fabian; Pease, Lindsay; Strock, Jeff; Vetsch, Jeff
    In this episode of the Nutrient Management Podcast, five U of M researchers discuss drainage research. Could there be different nitrogen guidelines in the future based on drainage status? Is older research in Minnesota on drainage systems still valuable or have changes in climate and crops mean we should re-look at some of these topics? Where do conservation drainage technologies such as bioreactors fit economically in our cropping systems? Thank you to Minnesota's Agricultural Fertilizer Research and Education Council (AFREC) for supporting the podcast.

    Episode 49: Challenging Spring Weather
    (2022-05-02) McDivitt, Paul; Carlson, Brad; Pease, Lindsay; Strock, Jeff; Nelson, Anne
    In this episode of the Nutrient Management Podcast, we discuss challenging spring weather and how growers can move forward. What are field conditions looking like around Minnesota? After a cold, wet April with not much fieldwork, what should growers be thinking about heading into May? How can growers better manage nutrients, and water, as Minnesota's climate gets increasingly wetter? Guests: Brad Carlson, Extension educator - nitrogen management & water quality (Mankato); Lindsay Pease, Extension nutrient and water management specialist - NWROC (Crookston); Jeff Strock, U of M soil scientist - SWROC (Lamberton); Anne Nelson, Extension educator - water resources (St. Cloud). Additional resources: Spring nutrient management decisions: How can growers save on fertilizer costs this year?, Taking soil samples for nitrogen analysis could pay big this year, Fertilizer recommendations by crop, Gopher Coffee Shop podcast: Corn planting outlook, Strategic Farming: Field Notes launches May 11.

    (2023-08-09) Wilcox, Jack; Kaiser, Daniel; Carlson, Brad; Strock, Jeff
    In this episode of the Nutrient Management Podcast, we’re talking about the fall fertilizer outlook for 2023. What are growing conditions looking like around the state? What is the current status of fertilizer prices and availability in Minnesota? What should growers be thinking about heading into fall? There is a lot of talk about environmental issues related to fertilizer use and the potential for future regulation. How should that play into application decisions for this fall? Guests: Daniel Kaiser, Extension nutrient management specialist (St. Paul); Jeff Strock, Extension soil scientist (Lamberton); Brad Carlson, Extension educator (Mankato) .

    Episode 67: Edge of field N and P Reduction Strategies: What to Know About Conservation Drainage Practices
    (2023-12-11) Wilcox, Jack; Carlson, Brad; Christianson, Laura; Strock, Jeff
    In this episode of the Nutrient Management Podcast, we’re talking about edge of field N and P reduction strategies. What is an edge of field practice and why are they used? What specific practices do our panelists have experience with, and which have the most potential for use in Minnesota? Are these practices a farmer can pursue alone, or do they require local government to be involved? What assistance is available for farmers who are interested in one of these practices? Guests: Brad Carlson, Extension educator (Mankato); Laura Christianson, researcher, U of M Department of Soil, Water, and Climate (St. Paul); Jeff Strock, Extension soil scientist (Lamberton).

    Nitrogen loss: Lessons learned from the 2024 growing season
    (2024-11-07) Fernandez, Fabian; Strock, Jeff; Vetsch, Jeff; Pease, Lindsay; Carlson, Brad
    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?

    The Story of Nitrogen Episode 5- A Legacy of Salts
    (2021-11-22) Klinger, Greg; Bugeja, Shane; Dugan, Hilary; Strock, Jeff; Castellano, Mike; Barry, John
    If you want to understand how nitrogen behaves in the soil, it pays to think about two things: water and time. These two factors control when and how much nitrogen can be lost from soil. They also help explain why some landscapes accumulate the nitrate form of nitrogen while others do not. Join us as we discuss how nitrogen moves through soils, how we can control its losses, and the surprising connections between nitrate, road salt, and nuclear testing.
