Today we’re talking all about nitrogen-fixing biologicals. What's the best definition of a biological or biostimulant? Are they fertilizers, pesticides - or neither? In what ways do they interact with nitrogen in the field? Where and how are biological products tested? Which environmental factors might impact biologicals? How should they be properly transported and stored? How can farmers assess
Nitrogen conservation and water quality are the subject of today's Advancing Nitrogen Smart episode. There's lots to cover so we're splitting the episode up into two parts. Today in Part 1, Brad Carlson and Jeff Vetsch unpack different conservation solutions, and what might be achieved from their adoption. In what situations might buffer strips, cover crops, and corn genetics play their part?
Today on the podcast we focus on soybean nutrient management in western Minnesota. Our four panelists conduct research across Minnesota and North Dakota. They'll explain their research trials, and discuss some preliminary results. Also, what should growers keep in mind as we transition into 2025? What are the panelists' concerns about IDC? That and much more on our last episode of 2024. &
Nitrogen loss: Lessons learned from the 2024 growing season is the big topic on today's episode of the Nutrient Management Podcast. What N application practices looked particularly bad in 2024? Some farmers are saying they are no longer going to apply fall N based on how 2024 played out. Is this warranted, or is it an overreaction? Is there any data back from split-application trials, or
In episode 12 of the Advancing Nitrogen Smart series Brad and Dan talk in detail about nitrification inhibitors. What are the two types of inhibitors, and what are best practices for incorporation? How do soil type, temperature, and precipitation factor into farmer decision-making? How much time does a nitrification inhibitor buy you? In what circumstances should inhibitors be avoided altogether?
By: Jack Wilcox, Extension communications generalistAccess to unbiased, research-based information is essential for farmers and agricultural professionals. On the Advancing Nitrogen Smart podcast series, Extension educator Brad Carlson and Extension nutrient management specialist Dan Kaiser examine and unpack the latest in nitrogen management research and recommendations, enabling farmers to make
In this episode of the Nutrient Management Podcast, our panelists discuss liming in detail. What kind of variation is there in liming recommendations? Since pH changes aren’t instant, when is the best time to apply limestone? Is lime application economically justified, and in what circumstances? What should growers know about selecting liming materials? What other bits of advice do our panelists
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
This episode of the Nutrient Management Podcast is our annual fall fertilizer outlook for 2024. 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
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?TRANSCRIPTGuests:Brad Carlson,
In this episode of the Nutrient Management Podcast, we’re talking about phosphorus fertilizer guidelines in Minnesota and throughout the Midwest. What are current state guidelines throughout the region, and are they satisfactory? Should farmers forgo taking a soil test to measure P levels, or should the test be prioritized? Might state phosphorus guidelines need to be revised, and if so, in what
In the 6th episode of the Advancing Nitrogen Smart series, we’re taking an up-close look at the nitrogen transformation process. We’ll talk more about temperature conditions, rainfall versus drainage, and what makes knowing these details so valuable to Minnesota farmers and producers (as well as growers around the world). TRANSCRIPTGuests:Brad Carlson, Extension educator (Mankato)Daniel Kaiser,
In this episode of the Nutrient Management Podcast, we’re talking about manure application in 2024. What’s the value of manure today, given that fertilizer prices are still elevated compared to 2018 and 2019? What does long-term research show us about manure’s value, and how might this information benefit growers and producers? Which manure best management practices (BMPs) help growers be most
In the 5th episode of the Advancing Nitrogen Smart series, we’re talking about the ways the soil stores water, and how nitrogen transforms in that soil under different climate conditions. We’ll discuss field saturation and the water budget, heat units and how to track them, and how these trends have changed throughout MN over the last 60 years.TRANSCRIPTGuests:Brad Carlson, Extension educator (
In the 4th episode of the Advancing Nitrogen Smart series, we’re talking in-depth about sidedress. What are the growth stages critical to growers when sidedressing? What are options for assessing whether to add supplemental N, and how should they be used? How do wet conditions affect yield, and are rescue treatments economically advantageous? What sensing methods are available (such as drones)
In this episode of the Nutrient Management Podcast, we’re talking all about biologicals. What should companies consider as they test their biological products? Can growers reduce their nitrogen requirements due to biological use? Is there new research out there that tells us about biologicals’ effectiveness? What should growers watch out for when they consider companies’ claims about biological
In this episode of the Advancing Nitrogen Smart series, we’re talking in-depth about nitrogen best management practices. How are BMPs calculated, and how do they change over time? What should growers keep in mind regarding regional adjustments in the BMPs? What kinds of risks are the BMPs designed to address? How do the 4 Rs figure into Minnesota's nitrogen best management practices? TRANSCRIPT&
Understanding how nitrogen behaves in the environment is more important than ever. And when growers have access to unbiased, research-based information, they’re better equipped to make farm-specific nitrogen management decisions.Here at Advancing Nitrogen Smart, we unpack and examine the latest up-to-date nitrogen data to help farmers maximize their profits while at the same time minimize
Understanding how nitrogen behaves in the environment is more important than ever. Having access to unbiased, research-based information is crucial for growers as they try to make the most efficient input decisions for their farms, maximizing profits while at the same time minimizing nitrogen loss to the environment.For the last decade, the Nitrogen Smart curriculum at University of Minnesota
In this episode of the Nutrient Management Podcast, we’re talking about recent cover crop challenges and potential solutions. What were the cover crop issues for 2022 and 2023?
