One of the most notable benefits of nitrogen-based fertilizers is their ability to enhance plant growth and increase productivity. Nitrogen facilitates the production of chlorophyll, the pigment responsible for photosynthesis. This process is vital for converting sunlight into energy, allowing plants to grow and produce food. Consequently, nitrogen fertilizers can positively impact the growth phases of crops like wheat, rice, and corn, leading to increased yields that support a growing global population.
