Plants require more than just water and sunlight to grow. They also require many nutrients found in the soil. One of the most important nutrients required for plant growth is nitrogen. Nitrogen is used to build plant proteins and nucleic acids, including DNA.

In short, nitrogen is what makes your grass green, and the greener the grass, the more photosynthesis can occur and the thicker the lawn gets. But be careful! Too much nitrogen can create big problems for your lawn.
