    Episode 15: Considerations for Fall Fertilizer Applications
    (2019-08-07) McDivitt, Paul; Kaiser, Dan; Vetsch, Jeff; Carlson, Brad
    In this episode of the Nutrient Management Podcast, we discuss considerations for fall fertilizer applications. Given the conditions this past spring, if fertilizer was applied to a field which didn't end up getting planted, does fertilizer still need to be applied this fall for the 2020 crop? Is there anything new related to nitrogen which growers should be considering for fall application considering our recent wet growing seasons? What about P and K? And micronutrients?

    Episode 17: Field to Stream to Gulf - Part 1
    (2019-10-01) Klinger, Greg; Kuehner, Kevin; McDivitt, Paul
    In this special episode of the Nutrient Management Podcast, Extension Educator Greg Klinger continues a discussion about the Root River Field to Stream Partnership in southeast Minnesota. He's joined by Kevin Kuehner from the Minnesota Department of Agriculture as they work to understand how much of the soil and nutrients that leave farm fields in the region actually end up in streams, rivers, and beyond. Part One examines a fundamental question: what happens when soil and nutrients leave a field? Greg and Kevin explore how dissolved nutrients and soil-attached nutrients move at different speeds through watersheds, road ditches as sediment control structures, the value of digging holes in the Driftless Area, and how we often underestimate the value of existing conservation practices.

    Episode 18: Field to Stream to Gulf - Part 2
    (2019-10-01) Klinger, Greg; Kuehner, Kevin; McDivitt, Paul
    In this special episode of the Nutrient Management Podcast, Extension Educator Greg Klinger continues a discussion about the Root River Field to Stream Partnership in southeast Minnesota. He's joined by Kevin Kuehner from the Minnesota Department of Agriculture as they work to understand how much of the soil and nutrients that leave farm fields in the region actually end up in streams, rivers, and beyond. Part Two shifts the focus to the larger Root River watershed, examining how a buildup of older sediment sources can muddy the waters, both literally and figuratively, for water quality. Greg and Kevin discuss the unexpected benefits of nuclear testing, regions trapped in their own history, when to focus on practices versus results, and making water walk instead of run.
