Agricultural micronutrients, though needed in small quantities, are fundamental to the health and productivity of plants. The essential micronutrients (Fe, Mn, Zn, Mg, Cu etc.) are involved in a wide variety of physiological processes that help plants grow, thrive, and produce high-quality crops. They play vital roles in everything from photosynthesis to disease resistance, soil health to stress tolerance, and even reproductive success.

Iron (Fe): Iron is central to the production of chlorophyll and acts as a cofactor for enzymes involved in photosynthesis. Its deficiency often leads to chlorosis, impairing the plant's ability to conduct photosynthesis efficiently.
 

Manganese (Mn): Manganese is crucial for photosynthesis, as it helps in the production of oxygen during the process. Manganese also activates enzymes that facilitate nutrient uptake and overall plant metabolism.
 

Zinc (Zn): Zinc is involved in the synthesis of proteins, the formation of plant hormones, and the activation of numerous enzymes. It's particularly important for seed production and cell division.
 

Copper (Cu): Copper plays a role in photosynthesis and respiration by supporting enzymes responsible for energy transfer, the formation of lignin,  and a component of plant cell walls that adds structural integrity.
 

Magnesium (Mg): Magnesium is the central core of the chlorophyll molecule in plant tissue. It also helps to activate specific enzyme systems, which build, modify, or break down compounds as part of a plant's normal metabolism.
