Fall manure application: Plans, resources & strategies for Minnesota farmers

On this episode of the Nutrient Management Podcast, we talk all about fall manure application. What should be on a farmer's to-do list to prepare for fall application? What names need to be on an operation's emergency response plan, and what kind of PPE should farmers keep nearby? How much lead time does a lab need to return sample results? If a farmer plans to work with a commercial applicator, what can they do ahead of time to ensure a successful season? All of this, plus a farmer Q&A, on-farm research advice, an update on ManureDB and more on today's show.Guests:Melissa Wilson, Extension manure nutrient management specialist (St. Paul)Chryseis Modderman, Extension manure nutrient management specialist (Morris, MN)Nancy Bohl Bormann, researcher, manure and nutrient management (St. Paul)Eduardo Garay, on-farm research manager, manure management (St. Paul)Additional Resources:How to put together a manure management planUMN Manure (YouTube)ManureDBManure management: Agitation and pumpingFor on-farm research inquiries, contact Eduardo Garay at: [email protected]—For the latest nutrient management information, subscribe to the Nutrient Management Podcast.

Today on the Advancing Nitrogen Smart Podcast we take a close-up look at bioreactors as an edge-of-field practice. How does this important tool work, and how does it help mitigate nitrate loss? What types of carbon sources have traditionally been used in a bioreactor, and what types of carbon could be used in the future? How are bioreactors incorporated in to a farmer's operation, and how are they maintained? How effective and efficient are bioreactors? What's on the horizon for the next generation of bioreactor technology? All this and more on today's episode.Guests:Brad Carlson, Extension educator (Mankato)Jeff Strock, Extension soil scientist (Lamberton)Additional Resources:Nitrogen and phosphorus removal from agricultural drainage water by a modular bioreactorBioreactor research3 takeaways from the Conservation Drainage Network’s annual meetingEdge of field N and P reduction strategies: What to know about conservation drainage practicesNitrogen Smart---For the latest nutrient management information, subscribe to the Nutrient Management Podcast.

It’s that time of year again; time for the Fall Fertilizer Outlook on the Nutrient Management Podcast. Given the overall economics of crop production right now, how should farmers be approaching their fertilizer decisions this fall? What are some regional differences with respect to fertilizer management this year? There has been a renewed focus on the issue of water quality in Minnesota - how should this affect farmers’ decision-making? How many fertilizer decisions can be pushed off until spring?

On today's Advancing Nitrogen Smart Podcast, Brad Carlson and Melissa Wilson explain aspects of Minnesota laws and regulations that manure applicators should be aware of. What are the requirements for manure testing, and how often should you do it? What are some general restrictions for manure application in Minnesota? How do buffers and setbacks help you? What kinds of documents should be incorporated into a manure management plan? What contingencies should be put into place in the case of an emergency?

Nitrogen loss is the topic today on the Advancing Nitrogen Smart podcast. Soil conditions and chemistry are factors that make nitrogen prone to loss, but how does the N loss process actually happen? What's left over in the field after that process occurs, and where does the lost nitrogen go? What do denitrification, leaching and volatilization mean? How can the 4 Rs (right rate, right source, right placement, right timing) help growers minimize risk? How do nitrification inhibitors, microbes, and soil types fit in to the picture? All that and more in today's conversation.Guests:Brad Carlson, Extension educator (Mankato)Dan Kaiser, Extension nutrient management specialist (St. Paul)Additional resources:Wait, consider your options before applying nitrogen this fallVideo: What to know about nitrogen inhibitors and other enhanced efficiency fertilizersField Notes talks about what to expect after heavy June rainsVideo: Fall vs. spring urea in MinnesotaNitrogen Smart---For the latest nutrient management information, subscribe to the Nutrient Management Podcast.

On this episode of Advancing Nitrogen Smart, Brad and Dan take some of the mystery out of variable rate N. What are we trying to accomplish when we use a variable rate management practice? What kinds of field conditions might benefit from VRN, and which conditions should be avoided with VRN? How might the other 3 R's (Timing, Source & Placement) play a part in rate decision making? All that and more on today's show. Guests:Brad Carlson, Extension educator (Mankato)Dan Kaiser, Extension nutrient management specialist (St. Paul)Additional resources:Is variable rate nitrogen based on yield maps a good idea?Variable rate nitrogen: What farmers should knowMaking sense of Minnesota’s corn fertilizer guidelines: Frequently asked questions and answersFertilizing corn in MinnesotaNitrogen Smart---For the latest nutrient management information, subscribe to the Nutrient Management Podcast.

Today on the Nutrient Management Podcast we discuss nutrient management for irrigated crops in Minnesota. How many irrigated acres are there in Minnesota? What are some of the benefits and risks of irrigation? In what ways can risks be mitigated - through timing, cover crop adoption and / or other general soil health practices? What should growers know about the latest irrigation research in Minnesota? If a farmer is considering adopting irrigation practices, what should they focus on first? This and much, much more on today's episode.Guests:Daniel Kaiser, Extension nutrient management specialist (St. Paul)Carl Rosen, Extension irrigation specialist, Dept. of Soil, Water, and Climate (St. Paul)Vasu Sharma, Extension irrigation specialist, Dept. of Soil, Water, and Climate (St. Paul)Additional Resources:IrrigationResearch shows precision irrigation technology can improve irrigation water productivity in cornCould adding irrigation to Minnesota corn fields help reduce nitrate losses to groundwater?How do wet and dry years affect corn yield and nitrate leaching under different irrigation and nitrogen management strategies?Effect of variable rate irrigation and nitrogen fertilizer rates on crop productivity and water quality---For the latest nutrient management information, subscribe to the Nutrient Management Podcast.

This month's episode of the Nutrient Management Podcast is all about sulfur. Fertilizer guidelines go through changes periodically, but are there any upcoming changes to the sulfur fertilizer guidelines specifically? What does current research tell us about managing sulfur for Minnesota crops? Were there any surprising results? Should growers proactively add sulfur to crops out of caution, or is that practice unnecessary? What are some final takeaways that our panelists want Minnesota farmers to know about?

This week on Advancing Nitrogen Smart Melissa Wilson and Brad Carlson talk about manure sampling and testing. What are some sampling guidelines to be aware of in Minnesota? How variable is nitrogen in one type of manure, and then from type to type? How could changes to a farmer's overall operation affect manure nutrient content? How should manure samples be stored? Safety is huge - what do farmers need to know about staying safe when working with manure? Oh, and how do you prevent sample jars from exploding in the mail? This, and lots of manure info on today's show. Guests:Brad Carlson, Extension educator (Mankato)Melissa Wilson, Extension manure nutrient management specialist (St. Paul)Additional resources:2025 Certified Manure Testing LaboratoriesNitrogen availability of different manure types: What we know and what we are researchingIntroducing ManureDB: A new way to view manure variability and trendsManure managementManure Land Application: Minimum Requirements---Click here to listen to all Advancing Nitrogen Smart podcast episodes.For the latest nutrient management information, subscribe to the Nutrient Management Podcast.

Today on the Advancing Nitrogen Smart podcast series, Brad and Dan tell us how the Maximum Return to Nitrogen (MRTN) approach to N rate recommendations is calculated. What does the MRTN actually measure for farmers? What's the reason the MRTN recommendations were created? What kind of / how many rate trials are used to build the dataset? Does the MRTN rate recommendation approach work well in all Minnesota regions?
