Of all the essential nutrients, nitrogen is required by plants in the largest quantity and is most frequently the limiting factor in crop productivity. 1  In plant tissue, the nitrogen content ranges from 1 and 6%.
However, the primary nutrients are no more important than the other essential elements since all essential elements are required for plant growth. Remember that the âLaw of the Minimumâ tells us that if deficient, any essential nutrient can become the controlling force in crop yield. The intermediate nutrients are sulfur, magnesium, and calcium.
