Micronutrients
The plant-based nutrients, which are needed in very small amounts, are primarily in charge of repairing damaged cells and tissues and preventing infectious diseases by battling pathogens like bacteria, viruses, fungi, etc. that cause disease. Calcium, iron, vitamins, minerals, iron, and vitamin C are examples.
Role of micronutrients in Plants
Copper
- Many proteins have copper as a structural component.
- Plastocyanin, a copper protein that serves as an electron carrier in the electron transport chain of photosynthesis, is crucial for the process of photosynthesis.
- Necessary for the respiration process.
- Activate a number of enzymes.
- Participates in the metabolism of cell walls.
Manganese
- It’s necessary for photosynthesis.
- Chlorophyll is made with the help of manganese.
- It also stimulates the metabolism of nitrogen.
Zinc
- Basically, it is necessary for the metabolism of carbohydrates, phosphorus, and tryptophan production.
- Alcohol dehydrate-gas, carbonic anhydrase, lactic dehydrogenase, hexokinase, and carboxypeptidase are •Enzymes that contain zinc as a component.
Iron
- Compared to other micronutrients, iron is needed in higher concentrations. It aids in the activation of enzymes and is a crucial component of protein.
Boron
- Boron is crucial for controlling plant hormone levels and fostering healthy growth. Boron enhance the growth and retention of flowers, the lengthening and germination of pollen tubes, and the development of seeds and fruits.
Molybdenum
- The transition metal molybdenum, in the form of molybdate, is crucial for plants because it is used by several enzymes to catalyze the most significant reactions in nitrogen acclimation, phytohormone synthesis, purine breakdown, and sulfite detoxification.
Chlorine
- Osmotic and stomatal control, the evolution of oxygen in photosynthesis, and disease resistance and tolerance are only a few of its roles in plant growth and development. If the soils are lacking in this nutrient, Cl increases the yields and quality of many crops, such as onions and cotton, at acceptable levels of availability.

Macronutrient |
| Need in smaller amounts are termed micronutrients. | Need in larger amounts are termed Macronutrient |
| Boron, copper, manganese, iron, chlorine, and molybdenum. | Sulfur, nitrogen, carbon, phosphorus, calcium, potassium, and magnesium. |
| Micro-nutrients contribute to plant growth and disease prevention | Macronutrient Provides the energy required for the metabolic system. |
| Are present in fruits, vegetables, eggs, fermented foods, green leafy vegetables, etc. | Are present abundantly in cereals, fish, legumes, meat, nuts, oilseeds, potatoes, yam, etc |
| Micronutrients are also called trace elements | Macronutrients known as major elements |
Role of Macro and Micro-Nutrients in Plants
The naturally occurring inorganic nutrients found in food and soil that are necessary for the healthy operation of an animal or plant’s body are known as minerals. Minerals are essential to human survival. Micronutrients, such as boron, copper, and others, are needed by plants in tiny amounts, whereas macronutrients, such as nitrogen and phosphorus, are needed in larger quantities.
