Turfgrass also functions as a noise barrier. Studies at the Riverbank Acoustical Laboratory in Geneva, Illinois, found Kentucky bluegrass turf more sound absorbent than a heavy carpet on a felt pad. One of the most significant by-products of a living, green backdrop is its effect upon the atmosphere. The average lawn traps significant amounts of carbon dioxide, peroxyacetyl nitrates, and ozone as well as particulate matter. A most important effect is the prevention of soil erosion and enhancement of ground water recharge.
Research shows infiltration is much higher on turfed areas than on areas of bare ground.
The higher infiltration prevents water from running off and encourages it to enter the groundwater stream. Grass roots bind the soil more effectively than any other plant. Many gardeners enjoy maintaining a quality turf. Others despise lawn work and demand a low-maintenance turfgrass. Still others are confused about how to keep a lawn.
