Role of Critical Minerals for Plant Growth

Calcium: Is a key structural component of cell walls. It is also part of many enzymes. It is especially critical to cell division and therefore young plant development. 


Molybdenum: Is necessary for the synthesis of organic phosphorous compounds. It is an essential component in two enzymes that convert nitrate into nitrite (a toxic form of nitrogen) and then into ammonia before it is used to synthesize amino acids within the plant. It also needed by symbiotic nitrogen fixing bacteria in legumes to fix atmospheric nitrogen.


Phosphorous: Is essential for all living organisms. Plants must have phosphorus for normal growth and maturity. Phosphorus plays a role in photosynthesis, respiration, energy storage and transfer, cell division, cell enlargement and several other processes in plants.


Potassium: Though not part of any plant structural component, it plays a key role in water movement into and out of cells. Plants low in potassium will often wilt as they won't be able to adequately protect cells from losing water via evaporation. 

Manganese: Many processes are dependent on Manganese, including chloroplast formation, photosynthesis, nitrogen metabolism and synthesis of some enzymes. 


Iron: Without iron a plant can’t produce chlorophyll, can’t get oxygen and therefore won't get green. It is also critical to nitrogen fixation- the process by which atmospheric nitrogen becomes available to plants. 


Magnesium: Is the center of the chlorophyll molecule and therefore essential to photosynthesis. It is also an activator of enzymes in the creation of ATP and plays a vital role in plant respiration.  


Sulphur: Along with calcium and magnesium, it is considered one of the most important secondary plant nutrients. It helps in the formation of important enzymes and assists in the formation of plant proteins. It is needed in very low amounts, but deficiencies can cause visible loss of vitality.
