The distinction between macronutrients and micronutrients primarily lies in the quantities that plants need from each. Macronutrients are essential nutrients that plants require in larger amounts for their growth and development. These include nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur. These elements play vital roles in processes like photosynthesis, energy transfer, and nutrient transport within the plant.

In contrast, micronutrients, which include iron, manganese, zinc, copper, molybdenum, and boron, are needed in much smaller quantities. Although they are required in lesser amounts, they are still crucial for plant health and function, as they often serve as cofactors for enzymatic reactions and are involved in various physiological processes.

Understanding the requirements for both macronutrients and micronutrients is vital for effective crop management and achieving optimal plant growth.
