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.Item Episode 23: Nitrogen Management(2020-02-13) McDivitt, Paul; Carlson, Brad; Kaiser, Dan; Vetsch, Jeff; Cates, Anna; Sharma, VasuIn 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?Item Episode 24: Optimal Phosphorus and Potassium Levels in the Soil(2020-04-02) McDivitt, Paul; Vetsch, Jeff; Pease, Lindsay; Kaiser, DanIn 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?Item Episode 25: Biostimulants(2020-04-29) McDivitt, Paul; Kaiser, Dan; Pagilari, Paulo; Rosen, CarlIn this episode of the Nutrient Management Podcast, three U of M researchers discuss biostimulants.
