Examples of macro-nutrients include nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur. Nitrogen is crucial for leaf and stem growth, phosphorus supports root development and flowering, potassium aids in overall plant health and disease resistance, calcium contributes to cell structure and ...

Macro-nutrients are essential nutrients required by plants in relatively large quantities for their growth and development. They are called macro-nutrients because plants need them in larger amounts compared to micro-nutrients to support their basic metabolic functions.
