Nitrogen and sulfur: In-season application, nutrient interactions, precision tech & more

UMN Extension Nutrient Management Podcast

In this episode of the Nutrient Management Podcast, we’re talking about nitrogen and sulfur application. What does current nitrogen and sulfur research mean for Minnesota growers? What do we know about the relationship between N and S in crops? What -if any- considerations should farmers make when applying S? Do N application rates need to be changed? With an earlier planting window this year will there be any issues related to N and S growers should be concerned about?

Guests:

• Daniel Kaiser, Extension nutrient management specialist (St. Paul)
• Yuxin Miao, Assistant Professor of Precision Agriculture and Nutrient Management (St. Paul)
• Jeff Coulter, Extension corn agronomist (St. Paul)
• Fabian Fernandez, Extension nutrient management specialist (St. Paul)
