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.

Guests

• Brad Carlson, Extension educator (Mankato)
• Dan Kaiser, Extension nutrient management specialist (St. Paul)

Additional resources

• Nitrogen Conference (held annually in February; past videos are available online)
• Four things I’ve learned about nitrogen management for corn based on a decade of research in Minnesota
• Nitrogen Nuggets (YouTube playlist)
• Understanding nitrogen in soils

It's December and we're rounding out the year with an in-depth discussion on cover crops here on the Nutrient Management Podcast. What are panelists' observations regarding covers with lower seeding rates? What are some pros and cons relating to erosion or nutrient uptake? Does planting early at a lower seed rate vs. planting later with a higher seed rate result in the same outcome? What are some weed control characteristics of cover crops? What advice do our panelists have for farmers new to cover crops? What kinds of state and local resources are available for growers? All this and lots more on today's show so be sure to tune in.

Today on the Nutrient Management Podcast we're turning our attention to micronutrients. What does current research tell us about micronutrients - for corn specifically - that growers need to consider? Boron is another important micronutrient in Minnesota. What should farmers be aware of regarding boron? Is tissue sampling the answer to help predict where some of these micronutrients are needed? What are other important micronutrient takeaways? All this and much more on today's episode.
