Turfgrass does more than lay there. It works hard to improve water, air and soil quality.
Lawns help water quality by preventing erosion, filtering runoff and helping the soil absorb water. Turf traps dust and produces oxygen. This helps air quality. Grass adds organic matter to the soil as it sheds plant parts during its lifecycle. And, adding organic matter is one of the best ways to improve soil quality.
Turfgrass also reduces air temperatures. As water is lost from the plant due to heat or its own natural processes, surrounding temperatures drop by up to 14 degrees Fahrenheit. This makes your yard a cool place to be on hot summer days and reduces home air conditioning costs.
