UMN Extension Nutrient Management Podcast

In this episode of the Nutrient Management Podcast, we’re talking about variable rate technology. What are some reasons that farmers might want to use variable-rate fertilizer instead of applying a single rate? Is there a difference between variable rating, different nutrient types? What are the technologies that are used to prescribe variable-rate fertilizer and what is the theory behind them? If farmers apply fertilizer at a variable rate, how should they evaluate those outcomes?

Guests:

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

Additional resources:

• Variable rate nitrogen and nitrogen advisory tools: Do they work?
• Fertilizer recommendation technology: What is success?

In this episode of the Nutrient Management Podcast, we’re talking about soil test myths. First, why is it important to discuss these pervasive myths surrounding soil tests? Myth 1: the Mehlich-3 test is a better test for farmers to consider: Myth 2: I can predict my nitrogen requirement with the cation exchange capacity test. Myth 3: K base saturation is the better way to predict potassium. Myth 4: I need to run an analysis of all micronutrients.
