Macro-nutrients are essential elements required by plants in relatively large quantities for their overall growth and structural development. Examples include nitrogen, phosphorus, potassium, calcium, magnesium, and sulphur. In contrast, micro-nutrients are essential elements needed by plants in very small quantities or trace amounts for specific enzymatic functions. Examples of micro-nutrients include iron, manganese, boron, zinc, copper, molybdenum, and chlorine. Both groups are vital for plant survival.
