Item Episode 12: 2019 Research Round-Up(2019-07-09) McDivitt, Paul; Vetsch, Jeff; Klinger, Greg; Nelson, Anne; Fernandez, Fabian; Miao, Yuxin; Sims, Albert; Pease, Lindsay; Sharma, Vasu; Carlson, Brad; Wilson, Melissa; Pagliara, Paulo; Kaiser, DanielIn this episode of the Nutrient Management Podcast, University of Minnesota researchers meet in Crookston at the Northwest Research and Outreach Center to discuss their ongoing research across the state.Item Episode 13: Part 1: Soil and Nutrient Loss in Southeast Minnesota(2019-07-22) Klinger, Greg; Kuehner, Kevin; Meiners, RonIn 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.Item Episode 14: Part 2: Soil and Nutrient Loss in Southeast Minnesota(2019-07-22) Klinger, Greg; Kuehner, Kevin; Meiners, RonIn 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.Item Episode 17: Field to Stream to Gulf - Part 1(2019-10-01) Klinger, Greg; Kuehner, Kevin; McDivitt, PaulIn 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.Item Episode 18: Field to Stream to Gulf - Part 2(2019-10-01) Klinger, Greg; Kuehner, Kevin; McDivitt, PaulIn 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.Item Episode 28: Growing Conditions and Research Update(2020-07-20) McDivitt, Paul; Kaiser, Dan; Carlson, Brad; Pease, Lindsay; Klinger, GregIn this episode of the Nutrient Management Podcast, four U of M researchers discuss current growing conditions around the state and give us an update on their research projects. What questions have Extension researchers been getting this year from Minnesota growers and consultants about nutrient management? Is there anything growers should be aware of when making nutrient management decisions for 2021 based on this year's growing conditions?Item Episode 68: Nitrogen management in southeast Minnesota: What's the situation and what's being done?(2023-12-13) Vetsch, Jeff; Carlson, Brad; Klinger, GregIn this episode of the Nutrient Management Podcast, we’re talking about nitrogen management and water quality in southeast Minnesota. What is the situation in southeast Minnesota and why is it different from the rest of the state? What is the history of this work in southeast Minnesota on nitrogen issues? What is being done about the situation, and what are our current recommendations for southeast MN? Where does our panel see this issue going in the future? GuestsBrad Carlson, Extension educator (Mankato); Jeff Vetsch, U of M researcher (Waseca); Greg Klinger, Olmsted County Soil and Water Conservation District (Rochester).

How important is nitrogen applied prior to planting? What options are available to farmers to apply nitrogen at or after planting? Should inhibitors be included?Item The Story of Nitrogen Episode 0 - Trailer(2021-08-31) Klinger, Greg; Bugeja, ShaneItem The Story of Nitrogen Episode 1- The Leaky Barrel(2021-10-25) Klinger, Greg; Bugeja, Shane; Filstrup, Chris; Rabalais, NancyHow does nitrogen shape life in environments as diverse as cropland, lakes, and oceans? Why does nitrogen increase the abundance of life in some places while decreasing it in others? And why do we sometimes consider these changes "good" or "bad"? We start to tackle these questions in conversations with experts on Minnesota lakes and the Gulf of Mexico.

Legumes are plants that can take- or "fix" - nitrogen out of the air, where it exists in near limitless amounts, and add it to the soil. This ability to fix nitrogen is common in nature, in environments as diverse as fields, forests, lakes, deserts, and seas, and yet the demand for nitrogen by living things is often greater than the supply produced by nitrogen fixation. Why is this the case? We look at nitrogen in our water, forests, and cropland to get to the bottom of this fundamental question.

This episode tackles the question of how soil microbes are affected by nitrogen fertilizers and how this in turn changes the way we need to manage our soil. Along the way, we get some help from scientists Bruce Potter, Chelsea Carey, and Sada Egenreither, a few bad wildlife analogies, and Lucille Ball.

The amount of nitrogen the soil provides can change dramatically from year to year, leading to added complication for farmers. Are there ways to help us predict how our soil management, and other factors like the weather, influence the nitrogen that's available to crops?

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.

This episode is all about nitrogen fertilizers and how we decide what rate of fertilizer to apply to our ground. This is a question I and many others have tried to tackle in our careers, and one whose answers regularly surprise and humble us. This episode is also about another question, one which anyone can relate to regardless of whether they work in agriculture or not, one which every person will have a different answer to: "How good is good enough?"
