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.

Guests:

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