Download Solution PDFThe 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.
