The macro-nutrient provided by inorganic fertilization are:

The correct answer is Nitrogen, Phosphorous, Potassium.

Key Points

• Nitrogen (N): Promotes leaf growth and forms proteins and chlorophyll.
• Phosphorous (P): Aids in the development of roots, flowers, seeds, and fruit.
• Potassium (K): Enhances overall plant health, improves drought resistance, and boosts disease resistance.
• These three nutrients are commonly referred to as macronutrients and are crucial for plant growth and development.
• Inorganic fertilizers typically contain these nutrients in various formulations to enhance soil fertility.

Additional Information

• Macronutrients vs. Micronutrients:
  • Macronutrients are required in larger quantities compared to micronutrients, which are needed in trace amounts.
  • Micronutrients include elements such as iron, manganese, zinc, copper, molybdenum, and boron.
• Role of Nitrogen:
  • Essential for the synthesis of amino acids and proteins.
  • Vital for photosynthesis as it is a component of chlorophyll.
• Role of Phosphorous:
  • Crucial for energy transfer in plants through ATP (adenosine triphosphate).
  • Important for root development and flowering.
• Role of Potassium:
  • Regulates water uptake and loss in plants.
  • Activates enzymes involved in photosynthesis and respiration.
• Inorganic Fertilizers:
  • Common types include ammonium nitrate, superphosphate, and potassium chloride.
  • They are synthesized through chemical processes and provide readily available nutrients to plants.
