Four soil test myths that farmers should know

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.
