What are micronutrients primarily known as?

Micronutrients are primarily known as activators or catalysts because they play crucial roles in a variety of biochemical processes within plants. These elements, which include vitamins and minerals such as iron, manganese, zinc, and copper, are necessary in smaller quantities compared to macronutrients (like nitrogen, phosphorus, and potassium), yet they are essential for the overall health and growth of plants. Micronutrients often function by participating in enzymatic reactions, enhancing physiological processes, and helping to regulate metabolic functions.

Their role as activators or catalysts is vital since, without these elements, many essential biochemical reactions would not occur, leading to deficiencies that can manifest as various health issues in plants. Understanding this function highlights the importance of including micronutrients in fertilization and soil management practices to ensure optimal plant development and productivity.
