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.
