Nutrient Ladder

The illustration below is the AgriBio Systems Nutrient Ladder. This shows the priority or hierarchy of how minerals are needed and used 1st, 2nd, 3rd and so on.  Can you climb a ladder with the first few rungs missing?

Justus von Liebig's Law of the Minimum states that yield is proportional to the amount of the most limiting nutrient, whichever nutrient it may be.
