| Fall manure outlook: Updated application rates and best practices | 15 Oct 2026 | 00:29:17 | |
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 these, are there changes that farmers should make to their fall best practices? ManureDB (the online manure nutrient database) recently had a large data set added to it. What does the new data mean for the end user? Are micronutrients included in ManureDB's data? In the world of 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:

| Complexity in manure nutrient availability: Nitrogen, species & bedding | 06 Oct 2026 | 00:27:21 | |
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:

| Reducing N loss to water with land management principles & the 4Rs | 09 Sep 2026 | 00:36:49 | |
How do soil health practices—such as minimizing disturbance, maintaining ground cover, and promoting biological activity—interact with the 4Rs of nitrogen management to reduce runoff and nitrate leaching into water sources? How does nitrogen release (mineralize) or become tied up (immobilize) in residue depending on soil moisture, temperature, and microbial activity? Are biological soil tests (like the Haney test and Solvita CO₂ burst) precise tools for calculating exact fertilizer rates, or should they be considered general risk indexes? What role do strong soil structure and expansive root systems play in maximizing nitrogen uptake? Brad Carlson, Anna Cates and Dan Kaiser discuss this and much more on the 41st episode of the Advancing Nitrogen Smart podcast. Guests:

| Manure under a microscope: What variables affect nutrient value? (hint: they all do) | 30 Jul 2026 | 00:38:54 | |
Today on Advancing Nitrogen Smart we ask an unusual question: What is manure, really? We all know manure is made of the liquids and solids that pass through an animal's digestive system, but what has to happen for manure to become usable? Is all manure created equal, or do differences in animal type - and their feed - result in manure with variable nutrient values? How do factors like handling, storage and animal bedding impact available nutrients in manure? What are some of the long-term benefits of manure application? Is there an optimal time of year to apply manure? Brad Carlson and Melissa Wilson answer these questions and many more on this 39th episode of the Advancing Nitrogen Smart podcast. Guests:

| The 5 main pathways of nitrogen loss: What are they, and how can you increase efficiency? | 12 Jan 2026 | 00:42:48 | |
We return to first principles with a detailed discussion about nitrogen loss on today's Advancing Nitrogen Smart Podcast episode. The five terms that describe how nitrogen is lost from the soil are: leaching, denitrification, volatilization, crop removal and soil erosion & runoff. But what do those terms actually mean? How does nitrogen's chemistry change during loss? Do N loss processes (also called pathways) happen at the same speed? How do temperature and precipitation affect N loss pathways? How might farmers hedge against the risk of loss by incorporating the 4Rs into their N planning? All of this and much more on today's show.
