    Crystal Creek, Fillmore County Dye Tracing 2010
    (2010) Green, Jeffrey A; Kuehner, Kevin; Luhmann, Andrew J; Alexander Jr., E. Calvin
    Dye tracing was conducted at sinkholes in and around the Crystal Creek watershed in Bristol & Carimona Townships in Fillmore County. These traces were done as part of a cooperative effort between DNR, MDA and Fillmore County. The county and the MDA are working with landowners in the Crystal Creek watershed to study land management impacts on water resources. This area is underlain by Ordovician Galena limestone and is characterized by surface karst features. The predominant karst features are sinkholes and springs. The traces were done to begin to delineate the ground water basins (springsheds)that feed the springs that are the water sources for Crystal Creek. In karst areas like the Crystal Creek watershed, it is common for the ground water watershed to have different boundaries than the surface water watershed.

    Episode 13: Part 1: Soil and Nutrient Loss in Southeast Minnesota
    (2019-07-22) Klinger, Greg; Kuehner, Kevin; Meiners, Ron
    In this special episode of the Nutrient Management Podcast, Extension educator Greg Klinger facilitates 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, and Ron Meiners, retired Root River Soil and Water Conservation District Manager. In Part One, they explore the question: How do you build a soil and water conservation project that brings everyone to the table? The podcast tackles the ideas of critical source areas, the needed density and intensity of soil conservation practices, sediment conveyor belts, and all the other things you learn when you walk over 8,000 acres of fields for conservation practices.

    Episode 14: Part 2: Soil and Nutrient Loss in Southeast Minnesota
    (2019-07-22) Klinger, Greg; Kuehner, Kevin; Meiners, Ron
    In this special episode of the Nutrient Management Podcast, Extension educator Greg Klinger facilitates 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, and Ron Meiners, retired Root River Soil and Water Conservation District Manager. Part Two examines what you can learn when you install equipment that collects all the runoff water from a field. What nutrients are being lost in surface runoff? Critical times for runoff, the difference between high-runoff soils and high-erosion soils, what can be done to limit nutrient losses when the ground is frozen, and Olympic-size swimming pools of runoff are all discussed.

    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.
