Sulfur fertilizer and corn production: What to know

Long-term sulfur trial at Waseca: Continuous corn. 2021 is the third year at Waseca. Listen to the podcast to learn more.

In this episode of the Nutrient Management Podcast, three U of M researchers discuss sulfur.

• How has atmospheric sulfur deposition changed over time and why does it matter for farmers?
• How did the dry conditions this year impact sulfur availability? Do dry soils mean sulfur responses will be greater? 
• Do dry soils affect which source of sulfur growers should use? 
• What do we know about interactions between sulfur and other nutrients? 
• What should farmers thinking about applying sulfur for the 2022 crop keep in mind?
