Micro-elements are essential components for healthy growth and development of plants. These trace elements are required in very small amounts and play a significant role in various metabolic processes. Other terms used to describe micro-elements include trace elements, micronutrients, and minor elements. These synonyms refer to vital minerals such as zinc, copper, boron, iron, and manganese. They are important for the healthy functioning of enzymes and other metabolic activities. Lack of these nutrients in soil would result in stunted growth and reduced yield of crops. Understanding the importance of these micro-elements and their synonyms helps farmers and gardeners to maintain soil health and guarantee a healthy crop harvest.
