Your optimal N rate: Understanding its impact on yield, water quality, and the bottom line
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 how does this relate to a farmer's operation? What are some ways to address in-field variability when determining rate?
Guests:
- Brad Carlson, Extension educator (Mankato)
- Daniel Kaiser, Extension nutrient management specialist (St. Paul)
