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? These answers and many, many more on today's episode.

Guests:

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

Additional resources:

• Nitrification inhibitors and manure: Do they work?
• Video: What to know about nitrogen inhibitors and other enhanced efficiency fertilizers
