Micronutrients are essential elements required by plants in smaller quantities compared to macronutrients, but they are nonetheless crucial for various physiological processes and overall plant growth and development. Here are the essential micronutrients for plant growth along with common sources:

Iron (Fe)Essential for chlorophyll synthesis, electron transport, and enzyme activation.Iron sulfate iron oxide
Zinc (Zn)Involved in enzyme activation, protein synthesis, and hormone regulation.Zinc sulfate zinc oxide
Manganese (Mn)Required for photosynthesis, enzyme activation, and nitrogen metabolism.Manganese sulfate manganese oxide
Copper (Cu)Essential for enzyme activation, electron transport, and lignin synthesisCopper sulfate copper oxide
Boron (B)Involved in cell wall formation, pollen germination, and sugar transport.Borax, boric acid
Molybdenum (Mo)Required for nitrogen fixation, enzyme activation, and nitrate assimilationSodium molybdate
Chlorine (Cl)Involved in photosynthesis and osmotic regulation.Chloride salts, such as Sodium Chloride Potassium chloride
Nickel (Ni)Essential for nitrogen metabolism, urease activity, and hydrogen metabolism.Nickel sulfate, nickel chelates

These micronutrients are typically supplied to plants through soil applications, foliar sprays, or hydroponic nutrient solutions. It’s essential to ensure that plants receive adequate levels of all essential nutrients for optimal growth and development. However, excessive micronutrient levels can also be harmful to plants, so proper nutrient management and soil testing are crucial for maintaining nutrient balance.
