UMN Extension Nutrient Management Podcast

In this episode of the Nutrient Management Podcast, three U of M researchers discuss biostimulants. What are biostimulants and what products are currently on the market? What classes of products are gaining a larger foothold in agriculture? What does research in Minnesota say about these products? Should farmers be taking a greater look at biostimulants? Thank you to Minnesota's Agricultural Fertilizer Research and Education Council (AFREC) for supporting the podcast.

In this episode of the Nutrient Management Podcast, three U of M researchers discuss optimal phosphorus and potassium levels in the soil. What are some key takeaways that growers should know about interpreting soil tests? Environmentally, what is the threshold at which we should avoid applications to prevent significant nutrient loss? Is there really an optimal soil test level that farmers should shoot for? Thank you to Minnesota's Agricultural Fertilizer Research and Education Council (AFREC) for supporting the podcast.

In this episode of the Nutrient Management Podcast, three U of M researchers discuss nitrogen management. Should growers consider split-applying N? Is fall urea too risky? Is ESN worth the cost? Thank you to Minnesota's Agricultural Fertilizer Research and Education Council (AFREC) for supporting the podcast.

In this episode of the Nutrient Management Podcast, five U of M researchers discuss their 2019 research projects and what they'll be studying in 2020. Topics include sulfur sources, urea timing, split application of N, banding P and K, soil health tests, cover crops, irrigation management, variable rate N technologies, the pre-plant nitrate test, and more.

In this episode of the Nutrient Management Podcast, we discuss fall soil sampling. Is there a best time to take samples in the fall? What is a good strategy for sampling banded fields? Grid versus zone sampling, which is the better option? Thank you to the Minnesota Agricultural Fertilizer Research and Education Council (AFREC) for their support of this podcast.

In this episode of the Nutrient Management Podcast, we discuss precision agriculture and nutrient management. What is the current state of precision agriculture? Which areas can growers benefit the most from incorporating precision ag technologies into current farming systems? Is precision agriculture part of the answer for reducing nutrient loss to ground and surface waters? Thank you to the Minnesota Agricultural Fertilizer Research and Education Council (AFREC) for their support of this podcast.

In this episode of the Nutrient Management Podcast, we discuss fall fertilizer economics. How early is too early when planning nitrogen applications? Are we looking at a year where farmers should be considering inhibitors? What makes the most sense economically for all fertilizers this fall? Thank you to the Minnesota Agricultural Fertilizer Research and Education Council (AFREC) for their support of this podcast.

In Part Two of this special episode of the Nutrient Management Podcast, we shift 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. Topics include 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.

In Part One of this special episode of the Nutrient Management Podcast, we discuss what happens when soil and nutrients leave a field. Extension educator Greg Klinger is joined by Kevin Kuehner from the Minnesota Department of Agriculture and the Root River Field to Stream Partnership in southeast Minnesota. How much of the soil and nutrients that leave farm fields in the region actually end up in the streams and rivers of the region? 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 region, and how we often underestimate the value of existing conservation practices.
