The influence of the least nutrient

No matter how much the other plant nutrients are poured into the soil (illustrated by the heights of the columns), only as much as the level of the least ( Boron in this case) will be available to the plant.
So in order for the plant to take up all the N, P and K and other elements, the level of B, Ca, Cu, etc. must be brought up to the same level, otherwise only the quantity up to the level of the least element will be available.
All the plant nutrients placed in any growing medium can only be the equivalent of the level of the lowest element available for the production of a crop.
