Welcome to University of Minnesota Extension's Nutrient Management Podcast. Each month we bring you the latest research in nutrient management for crops and how you can incorporate the latest tips and best management practices to your farm.
Fall manure outlook: Updated application rates and best practices
It's early / mid October in Minnesota, which means it's time for the fall manure outlook on the Nutrient Management Podcast. Minnesota's manure application rate guidelines have been updated for corn-corn and corn-soybean rotations. What are some of the results of theses changes? What was the reason to update the guidelines? What weather conditions might we experience with the predicted 2026 Super El-Nino. Knowing theses, are there changes that farmers should make to their best fall practices? ManureDB (the online manure nutrient database) recently had a large data set added to it. What does the new data look like for the end user? Are micronutrients included in manureDB's data? In the world on-farm research, what’s currently happening and how can farmers get involved? Important upcoming events for manure technicians, and farmer questions round out today's episode of the Nutrient Management Podcast.
Guests:
Nancy Bohl Bormann, manure nutrient management researcher (St. Paul)
Chryseis Modderman, Extension manure nutrient management specialist (Morris)
Stephen Gregg, on-farm research manager and outreach specialist (St. Paul)

Complexity in manure nutrient availability: Nitrogen, species & bedding
Manure nutrient management is uniquely complex, and we discuss some reasons why on today's Advancing Nitrogen Smart episode. What specific factors make manure management far more complex than applying standard chemical fertilizer? How do digestive systems and diets cause nitrogen availability to differ across various livestock species? Why does nitrogen availability decline so rapidly when manure is left exposed on the soil surface, and how much may be lost to atmospheric evaporation within a just few days? How can farmers optimize their fertilizer investments and evaluate whether their crops received sufficient nitrogen using late-season testing? These questions and more on today's 42nd episode of Advancing Nitrogen Smart.
Guests:
Brad Carlson, Extension educator (Mankato)
Melissa Wilson, Extension manure nutrient management specialist (St. Paul)

Managing dry edible beans: Insights from four Midwest experts
Dry edible beans are an important Minnesota crop, and we explore them further on today's Nutrient Management Podcast. We talk with four experts from around the Midwest about your dry bean questions: What are some similarities and differences managing for dry edible bean versus soybean, for example? What should farmers keep in mind about growing in the Red River Valley, or Southern Minnesota, or elsewhere in the Midwest? What does recent research indicate pertaining to dry bean? What major yield-limiting factors do farmers need to be aware of when growing dry edible bean? All of this and much more on today's episode of Nutrient Management Podcast.
