Liebigs Law of the Minimum 

Many producers follow Liebig’s Law of the Minimum, which states that maximum yield is dictated by the most limiting nutrient. For Midwestern corn growers, that nutrient is often nitrogen in the spring. The problem is, many misinterpret Liebig’s Law to mean an investment in nitrogen is all that’s needed to maximize yield - but that’s only true if all other nutrients are supplied at 100% sufficiency. In this video, Dr. Robert Mullen points out the importance of not ignoring other limiting factors like potassium. Because if your field is short on K in spring, you could be short thousands in fall.
