Variable rate nitrogen: What farmers should know

UMN Extension Nutrient Management Podcast

Today we’re talking all about variable rate nitrogen. What underlying information do we need to make decisions about VRN? What areas in the field might be prone to N loss? Should you only add extra N to high-yielding areas, or could a low-yielding zone also show positive responses? What effect could your overall management strategy have on a variable rate response? All this and more on today's episode.

Guests:

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

Additional resources:

• Variable rate nitrogen and nitrogen advisory tools: Do they work?
• Nitrogen Smart
• Understanding nitrogen in soils
