What is the main role of Nitrogen in plants?

The primary role of Nitrogen in plants is to promote green, vegetative growth. Nitrogen is a key component of chlorophyll, the green pigment crucial for photosynthesis, which allows plants to convert sunlight into energy. It is also an essential part of amino acids, the building blocks of proteins, which are vital for various physiological processes in plants. Adequate nitrogen levels lead to lush, healthy foliage and vigorous growth, which are critical for overall plant development. This is why nitrogen is often associated with enhancing vegetative aspects, giving plants their characteristic green color and supporting their growth phases.
