On this episode of Advancing Nitrogen Smart we discuss methods and tools to account for soil and weather conditions as you execute your nitrogen management strategy. Which tissue and nitrate testing options are the most beneficial, and when should you test? How does the understanding the nitrogen cycle help you interpret these results? How do drought and /or saturated conditions affect available nitrogen? What can be reasonably achieved with rescue treatments? Why is it important to end your season with the right amount of residual nitrogen in the field? Brad and Dan discuss this - and much more - on today's show.

Guests:

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

Additional resources:

• Corn supplemental N rate calculator
• Soil Testing Laboratory: Farm / Field and Commercial Horticulture Crops
• Research Analytical Laboratory - tissue testing
• The nitrogen cycle - YouTube video
• Why understanding the nitrogen cycle is key to managing soil fertility

Today on Advancing Nitrogen Smart we’re talking about the nitrogen cycle and managing soil fertility. What does 'the nitrogen cycle' mean, and how does it affect your management strategy? In what ways do temperature and moisture slow down or speed up nitrogen's window of usability? What are nitrification, denitrification, volatilization, mineralization and immobilization? How well do inhibitors work, when should they be applied? How does organic matter affect the nitrogen cycle? All these answers and more on today's episode.

Cation exchange capacity and cation balancing are the topics of the day in this episode of the Nutrient Management Podcast. What are the definitions of cation exchange capacity and cation balancing? How is CEC measured, and are those estimates reliable? What does the research say about CEC and CB and their role in a nutrient management strategy? What should farmers remember about cation exchange capacity and cation balancing for their own operations?
