What is a Micronutrient?

Micronutrients are essential nutrients for plant growth that are only needed in very small (micro) quantities. The seven elements listed below are generally recognized as micronutrients, although other trace elements may also benefit some plants.

• Boron (B): Aids in production of sugar and carbohydrates, essential for germination of pollen grains and pollen tubes.
• Copper (Cu): Important for reproductive growth, catalyst for other plant reactions.
• Iron (Fe): Essential for formation of chlorophyll, carries oxygen, critical to photosynthesis.
• Manganese (Mn): Involved in breakdown of carbohydrates and nitrogen metabolism.
• Zinc (Zn): Essential for transformation of carbohydrates, regulates consumption of sugars.
• Chlorine (Cl): Necessary for ionic balance, plays a role in photosynthesis.
• Molybdenum (Mo): Essential cofactor for the function of enzymes involved in building amino acids and nitrogen metabolism.
