What does nitrogen do to lawns?
Nitrogen (N) promotes rapid growth and lush green color. Phosphorous (P) helps develop healthy root systems. Starter lawn fertilizers have a high phosphorous count for this reason, while fertilizers for established lawns have a relatively low amount.
How do I know if my lawn needs nitrogen?
Nitrogen Deficiency When lawns lack nitrogen, they can be susceptible to a weed invasion and a much lower number of grass clippings than usual after you mow the lawn. Some of the most common visible signs of a nitrogen deficiency include yellow or yellow-green grass, plus slow growth and low density of grass.
Does nitrogen help grass spread?
Nitrogen allows grass to grow new green foliage above the soil level which is then used by the plant to photosynthesize, generating energy for sustained root growth and disease prevention.
How much nitrogen is too much for grass?
How much is too much? According to Cornell University, you should never apply more than one pound of available nitrogen per 1,000 square feet at one time. Most lawn care experts will recommend that using slightly less fertilizer than you need is much safer than overusing too much.

Why is it important to add nitrogen to your lawn?

What does fertilizer do to a grass plant?
Fertilizers allow you to add more nitrogen to the soil for the plant to use and you get to choose whether or not that nitrogen added is readily available or slowly released for sustained feeding. Your chosen fertilization practices give you control over the nutrition your grass needs, which in turn helps the grass to grow.
