Environmental Benefits of Turfgrass
Scientific research has documented the many benefits of turfgrass to our environment. Today’s improved turfgrass varieties are very effective in reducing pollution. A thick healthy lawn traps and removes dust and dirt from the air. It also acts as a natural filter, reducing pollution by purifying the water passing through its root zone. The clean gentle strength of turfgrass is the most cost-effective method for controlling wind and water erosion. A thick, healthy Pro-Lawn-Plus lawn absorbs rainfall and prevents major run off.
Another often overlooked benefit of a healthy lawn is its tremendous cooling effect. On a hot summer day, lawns will be 30 degrees cooler than asphalt and 14 degrees cooler than bare soil. The front lawns of eight houses have the cooling effect of about 70 tons of air conditioning. That’s amazing when the average home has an air conditioner with just a three or four ton capacity. The cooling effect of irrigated turf reduces the amount of fuel that must be burned to provide the electricity which powers air conditioners.
The U.S. Environmental Protection Agency’s Chesapeake Bay Program pulled together a “panel of experts” to look at lawns, lawn care and the impact lawns have on water quality in the Chesapeake Bay.
The expert panel’s conclusion, based upon a review of all the science and research done on the topic, was that a “dense vegetative cover of turf grass” on a lawn reduces pollution and runoff. If your lawn is thin and sickly, pollution and runoff from a lawn increases dramatically. You can download their report below.
In other words, the healthier a lawn, the better it is at controlling pollution that can affect water quality in streams and rivers, and eventually the Chesapeake Bay.
