In this episode of the Nutrient Management Podcast, five U of M researchers discuss drainage research. Could there be different nitrogen guidelines in the future based on drainage status? Is older research in Minnesota on drainage systems still valuable or have changes in climate and crops mean we should re-look at some of these topics? Where do conservation drainage technologies such as bioreacto...

 In this episode of the Nutrient Management Podcast, three U of M researchers and independent agronomist Matt Wiebers discuss on-farm research and nitrogen rates. Matt walks us through his AFREC-funded on-farm research project and what he's seen the last few years with regards to nitrogen rates. University researchers weigh in with their thoughts on Matt's research and how recent university data c...

 In this episode of the Nutrient Management Podcast, three U of M researchers discuss nutrient interactions. What are nutrient interactions and how important are they to crops? Which nutrient interactions are of concern to crop producers? What can you do to avoid misinterpreting plant tissue analysis results due to nutrient interactions? Thank you to Minnesota's Agricultural Fertilizer Research an...

In this episode of the Nutrient Management Podcast, three U of M researchers discuss our manure nitrogen guidelines. What are the most important considerations when making a nutrient management plan for manure application? Is it possible to put a value on the nutrients in manure? How does manure fit in with the maximum return to nitrogen (MRTN) approach used in the current nitrogen fertilizer guid...

 In this episode of the Nutrient Management Podcast, three U of M researchers discuss liming. Which crops benefit the most from lime application? What should growers look for in a liming material? How are the university's lime recommendations developed? Thank you to Minnesota's Agricultural Fertilizer Research and Education Council (AFREC) for supporting the podcast.

In this episode of the Nutrient Management Podcast, four U of M researchers discuss fall fertilizer management. What were summer growing conditions like across Minnesota? Is there any nutrient management research currently underway that crop producers may be interested in? What should growers consider when making fall fertilizer decisions? Thank you to Minnesota's Agricultural Fertilizer Research...

In this episode of the Nutrient Management Podcast, two U of M researchers discuss manure management. What manure-related events and educational programming are coming up? What's the latest on the liquid swine manure sidedressing research project? How is the manure N & P credit study going? What should farmers keep in mind about manure management heading into fall? Thank you to Minnesota's Agr...

In this episode of the Nutrient Management Podcast, four U of M researchers discuss current growing conditions around the state and give us an update on their research projects. What questions have Extension researchers been getting this year from Minnesota growers and consultants about nutrient management? Is there anything growers should be aware of when making nutrient management decisions for...

In this episode of the Nutrient Management Podcast, three U of M researchers discuss alfalfa nutrient management. Why is managing soil inputs important for alfalfa producers? What are some key points that growers should consider when making nutrient management decisions for alfalfa? Does timing matter with alfalfa fertilizer application? Thank you to Minnesota's Agricultural Fertilizer Research an...

In this episode of the Nutrient Management Podcast, three U of M researchers and a special guest from the Minnesota Department of Agriculture discuss nitrogen economics. How does the sale of nitrogen fertilizer in Minnesota break down by source, and what trends have we seen in nitrogen use for crops in Minnesota? Are farmers shifting towards more on-farm storage of nitrogen fertilizer, and what do...

In this episode of the Nutrient Management Podcast, three U of M researchers discuss biostimulants. What are biostimulants and what products are currently on the market? What classes of products are gaining a larger foothold in agriculture? What does research in Minnesota say about these products? Should farmers be taking a greater look at biostimulants? Thank you to Minnesota's Agricultural Ferti...

In this episode of the Nutrient Management Podcast, three U of M researchers discuss optimal phosphorus and potassium levels in the soil. What are some key takeaways that growers should know about interpreting soil tests? Environmentally, what is the threshold at which we should avoid applications to prevent significant nutrient loss? Is there really an optimal soil test level that farmers should...

In this episode of the Nutrient Management Podcast, three U of M researchers discuss nitrogen management. Should growers consider split-applying N? Is fall urea too risky? Is ESN worth the cost? Thank you to Minnesota's Agricultural Fertilizer Research and Education Council (AFREC) for supporting the podcast.

In this episode of the Nutrient Management Podcast, five U of M researchers discuss their 2019 research projects and what they'll be studying in 2020. Topics include sulfur sources, urea timing, split application of N, banding P and K, soil health tests, cover crops, irrigation management, variable rate N technologies, the pre-plant nitrate test, and more.
