Magnesium is the key element in chlorophyll molecule. It is necessary for chlorophyll formation.

Sulfur is another very important element in plant life, it is necessary for protein synthesis in plants.

Phosphorous plays an important role in  process of cell devision , photosynthesis and respiration.

Potassium is very crucial in gaseous exchange ,it operates the opening and closing of stomata.
