What are micronutrients in relation to plant nutrition?

Micronutrients in plant nutrition refer to essential elements that plants require in very small amounts compared to macronutrients, which are needed in larger quantities. These micronutrients include elements like iron, manganese, zinc, copper, molybdenum, and boron, and they play crucial roles in various physiological processes in plants, including enzyme function, chlorophyll production, and overall plant metabolism.

The significance of micronutrients lies in their importance for plant health and development despite the small quantities required. Even though they are needed in trace amounts, a deficiency in any of these elements can lead to specific physiological disorders and can adversely affect plant growth and productivity. Therefore, the correct characterization of micronutrients as those applied in very small amounts accurately reflects their nature and the roles they play in plant nutrition.
