What is the function of nitrogen in fertilizers?

Nitrogen plays a crucial role in the growth and development of plants, particularly in promoting the growth of leaves and stems. As an essential nutrient, nitrogen is a key component of chlorophyll, the molecule that plants use to photosynthesize. This process allows them to convert sunlight into energy, facilitating the development of lush, healthy foliage and robust stems. Adequate nitrogen levels can result in increased leaf area, which is critical for maximizing light capture and enhancing overall growth.

While nitrogen impacts other aspects of plant development, such as root growth and fruit quality, its primary and most direct function in fertilizers is to promote vegetative growth. This characteristic of nitrogen is particularly valuable in the early growth stages of plants, where leaf and stem development is vital for establishing a robust structure capable of supporting future growth and productivity.
