Detailed explanation-1: -The primary macronutrients are Nitrogen (N), Phosphorus (P), and Potassium (K). Nitrogen is essential for plant development, since it plays a fundamental role in energy metabolism and protein synthesis. Nitrogen is absorbed by the plant in the form of a nitrate. This macronutrient is directly related to plant growth.

Detailed explanation-2: -Nitrogen, phosphorus and potassium, or NPK, are the “Big 3” primary nutrients in commercial fertilizers. Each of these fundamental nutrients plays a key role in plant nutrition. Nitrogen is considered to be the most important nutrient, and plants absorb more nitrogen than any other element.

Detailed explanation-3: -Together with nitrogen, P and K form the Big Three of crop nutrients. P plays a crucial role in plant processes like photosynthesis, respiration, and energy storage and transfer. K benefits include increased root growth, improved drought tolerance, and enhanced photosynthesis.

Detailed explanation-4: -Nitrogen, Phosphorus, and Potassium are examples of macronutrients. They are also known as major nutrients. They are called micronutrients because plants use them in large amounts. They are needed for their growth and survival.
