Fall fertilizer outlook for 2024: Current conditions, soil testing, and farmer finances

In this episode of the Advancing Nitrogen Smart series, we discuss probably the most important topic for many farmers - rate. What makes both over-application and under-application of nitrogen counter-productive in terms of yield? How does a Maximum Return To Nitrogen (MRTN) rate approach differ from a yield-based approach? What are long-term environmental consequences of over-application, and how does this relate to a farmer's operation? What are some ways to address in-field variability when determining rate? Guests:Brad Carlson, Extension educator (Mankato)Daniel Kaiser, Extension nutrient management specialist (St. Paul)Additional resources:Maximum Return To Nitrogen (MRTN) rate calculator Are you overspending on fertilizer?Best practices for nitrogen managementNitrogen Smart (online course)---For the latest nutrient management information, subscribe to the Nutrient Management Podcast.

This episode of the Nutrient Management Podcast is our annual fall fertilizer outlook. After such a challenging growing season throughout most of the state, how do things look headed toward harvest? Since most of the state went from being too dry last year to too wet this year, how should this affect the approach to fertility management? What role will fertility play in sound financial management this fall? What advice do our panelists give growers as we head into the fall?Guests:Daniel Kaiser, Extension nutrient management specialist (St. Paul)Brad Carlson, Extension educator (Mankato)Jeff Vetsch, U of M researcher (Waseca)Fabian Fernandez, Extension nutrient management specialist (St. Paul)Additional resources:Are you overspending on fertilizer?2024 Certified Soil Testing LaboratoriesNitrogen Fertilizer BMPs for Agricultural Lands---For the latest nutrient management information, subscribe to the Nutrient Management Podcast and never miss an episode.

In the 8th episode of the Advancing Nitrogen Smart series, we’re taking about timing. What makes understanding timing crucial to using nitrogen efficiently? Should growers apply in fall, and if so, what source should be avoided? Between which growth stages does corn take up the bulk of a field's N? What do weather extremes teach us about optimal timing? Do some timing decisions negatively affect farmers' finances? In what ways?Guests:Brad Carlson, Extension educator (Mankato)Daniel Kaiser, Extension nutrient management specialist (St. Paul)Additional resources:Understanding nitrogen in soilsNitrogen Fertilizer BMPs for Agricultural LandsDoes fall urea application reduce sugarbeet stand loss?---For the latest nutrient management information, subscribe to the Nutrient Management Podcast.

In this episode of the Advancing Nitrogen Smart series, our two experts discuss nitrogen pools. What are nitrogen pools, and where do we find them? How is N actually consumed by the plant, and what forms of N will plants take up more readily? What are some potential signs of N deficiency in the plant? How do nitrogen pools relate back to the 4R's, like timing?Guests:Brad Carlson, Extension educator (Mankato)Daniel Kaiser, Extension nutrient management specialist (St. Paul)Additional resources:Will soil microbes deliver nitrogen to my crop?

In this episode of the Nutrient Management Podcast, we’re talking about phosphorus fertilizer guidelines throughout Minnesota and the Midwest. What are current state guidelines throughout the region, and are they satisfactory? Should farmers forgo taking a soil test to measure their P levels, or should the test be prioritized? Might state phosphorus guidelines need to be revised, and if so, in what ways? What guidance or advice pertaining to phosphorus guidelines would our panelists tell growers?Guests:Daniel Kaiser, Extension nutrient management specialist (St. Paul)Antonio P.
