- Air quality
Turfgrass is a living organism. Each plant takes in carbon dioxide and converts it into simple sugars to use as food through the process of photosynthesis. As a byproduct of photosynthesis, oxygen is released into the atmosphere.
A turfgrass area measuring 2,500 square feet produces enough oxygen for a family of four to breathe. An average sized healthy lawn can capture as much as 300 pounds of carbon per year and a golf course fairway can capture 1,500 pounds per year. One soccer field can offset the carbon produced by a car driving 3,000 miles.
- Pollution filter
In 2013, an EPA Chesapeake Bay Program panel of experts concluded, based upon a review of extensive research, that a “dense vegetative cover of turfgrass” reduces pollution and runoff. More precisely, the average soccer field can absorb 50,000 gallons of water before runoff occurs. The fibrous root system stabilizes soil to reduce erosion and prevents the movement of sediment into creeks and rivers.
- Stormwater management
Landscaped areas reduce pollutants from leaching through the soil into the water supply or from entering surface water runoff. Turfgrasses filter stormwater excess and reduce sediment and pollutants from entering water bodies. Turfgrass plants also redirect the flow of water, slowing it and allowing more water to be absorbed by the soil, which aids in preventing soil erosion and flooding.
The overall environmental cooling effect of turfgrass can be understood by comparing it to air conditioning. The average home has an air conditioner with a three or four ton capacity. The California Energy Commission has found the cooling effect of an average size lawn is equal to about nine tons of air conditioning. A single high school baseball field provides up to 70 tons of air conditioning. This cooling effect is beneficial for athletes and for reducing electrical needs for buildings and homes.
- Wellness and stress
Green spaces have been shown to improve wellness and reduce stress. There is growing evidence that horticulture and natural grass found on sports fields and lawns is important on a human level. Plants lower blood pressure, reduce muscle tension related to stress, improve attention and reduce feelings of fear and anger or aggression.
In 2002, The University of California – Riverside conducted research to support that hospital stays are positively affected by turfgrass and green spaces. Patients in hospital rooms with a view of nature and lawns recover more quickly than similar patients in rooms with a view of building walls.
