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.
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 of plants.
Micronutrients are involved in various physiological and biochemical processes that are essential for proper plant growth and development. Some of their key roles include:
Enzyme Activation: Micronutrients act as cofactors for enzymes, enabling them to carry out vital metabolic reactions in plants.
Photosynthesis: Micronutrients are crucial for the synthesis of chlorophyll, the pigment responsible for capturing light energy during photosynthesis.
Hormone Synthesis and Regulation: Micronutrients play a role in the production and regulation of plant hormones, such as auxins, cytokinins, and gibberellins, which influence growth and development.
Nutrient Uptake and Transport: Micronutrients facilitate the absorption and movement of macronutrients within plants, ensuring their proper distribution and utilization.
EDTA and Non-EDTA Micronutrients:
Micronutrients are often supplied to plants in the form of chelates to enhance their availability and uptake. The two primary types of chelated micronutrients are EDTA (ethylene diamine tetraacetic acid) and non-EDTA chelates.
EDTA Chelates: EDTA is a widely used synthetic chelating agent that forms stable complexes with micronutrients. EDTA chelates are water-soluble and highly effective in delivering micronutrients to plants. They help prevent nutrient interactions, ensuring efficient uptake and utilization. However, EDTA chelates are susceptible to degradation in soil, limiting their long-term effectiveness.
Non-EDTA Chelates:Non-EDTA chelates, such as EDDHA (ethylenediamine-N, N'-bis(2-hydroxyphenylacetic acid)), DTPA (diethylenetriaminepentaacetic acid), and EDDHSA (ethylenediamine-N, N'-bis(2-hydroxyphenylacetic acid) sesquisodium salt), are gaining popularity due to their enhanced stability in alkaline and calcareous soils. These chelates have higher resistance to degradation, providing a longer-lasting and efficient supply of micronutrients to plants.

Micronutrients are vital for optimal plant growth and development. Iron, manganese, zinc, copper, boron, molybdenum, and chlorine are essential micronutrients that play diverse roles in plant physiology. EDTA and non-EDTA chelates are effective methods to supply micronutrients to plants, ensuring their proper uptake and utilization. The choice of chelating agent depends on the specific soil conditions and the micronutrient requirements of the plants. Understanding the roles of micronutrients and utilizing appropriate chelated forms can help promote healthy plant growth, increase crop yields, and prevent nutrient deficiencies.
