Micronutrients are essential elements that plants require in trace amounts for proper growth and development. These nutrients play crucial roles in various physiological and biochemical processes within plants. While macronutrients such as nitrogen, phosphorus, and potassium are needed in larger quantities, micronutrients are equally important for overall plant health. In this blog, we will explore the different types of plant micronutrients, their roles, and the significance of EDTA and non-EDTA forms of micronutrients.
Micronutrient
Types of Micronutrients:
There are seven essential micronutrients required by plants, each with its specific functions and deficiencies leading to distinct symptoms. These micronutrients include:
Iron (Fe): Iron is vital for chlorophyll synthesis, enzyme activation, and energy transfer in plants. Iron deficiency results in chlorosis (yellowing of leaves) in young leaves, while veins remain green.
Manganese (Mn): Manganese is involved in photosynthesis, enzyme activation, and nitrogen metabolism. Manganese deficiency leads to interveinal chlorosis and reduced growth.
Zinc (Zn): Zinc is necessary for enzyme activation, protein synthesis, and auxin production. Zinc deficiency causes stunted growth, chlorosis, and malformed leaves.
Copper (Cu): Copper plays a role in photosynthesis, enzyme activation, and lignin synthesis. Copper deficiency results in wilting, chlorosis, and leaf curling.
Boron (B): Boron is essential for cell wall formation, pollen germination, and carbohydrate metabolism. Boron deficiency causes brittle leaves, poor fruit set, and reduced growth.
Molybdenum (Mo): Molybdenum is crucial for nitrogen fixation and enzyme activation. Molybdenum deficiency leads to stunted growth, yellowing of leaves, and reduced nodulation in leguminous plants.
Chlorine (Cl): Chlorine is involved in photosynthesis, osmotic regulation, and stomatal movement. Chlorine deficiency results in wilting and necrosis of leaf margins.
Other than this, nowadays farmers are increasingly using the multi micronutrient fertilizers to supplement the essential micronutrients
