For homeowners:
Why focus on nitrogen?
Tips
- Always take soil samples at the same depth (for lawns 3-4”).
- Take many random core samples from the entire lawn.
- Mix soil in a plastic bucket and provide about a ½ cup of the composite sample.
- Provide as much lawn care background information as possible.

Nitrogen (N) is a very important nutrient for grass growth. Nitrogen produces vigorous growth, improves turf density, and gives grass its dark green color.
Soils and rainfall often do not supply enough nitrogen. For this reason you may need to fertilize your lawn.
Insufficient nitrogen levels can lead to poor growth, increased chance of certain diseases, and thin turf which can allow weed invasion and soil erosion.
However, too much nitrogen, beyond what the grass needs, can increase the presence of certain diseases, increase weed pressure, and pollute our drinking water and surface waters.
