Other Turfgrass Benefits to the Environment

Healthy lawns and other landscape plantings contribute to improved air quality by acting as traps for dust and particulate matter. This is especially true in urban areas where dust generated by motorized vehicles can be trapped and washed down into the soil. Nutrients or other contaminants carried as dust particles may then be used by the plant or broken down and used by soil microorganisms. Because a lawn completely covers a soil surface, soil particles are prevented from blowing around and being carried into the atmosphere where they can be transported and deposited in another area or region.

Lawns act as traps for dust and other particles.

Green plants are termed autotrophs. That is, they are capable of making their own food through the process of photosynthesis.

Photosynthesis - the grass plant's food machine.

Trees, shrubs, and the individual grass plants that collectively make up a lawn take in carbon dioxide (CO2) that when combined with water is converted into simple sugars. These sugars can then be further combined into a large array of other needed plant chemical products.

As a result of photosynthesis and uptake of CO2, oxygen (O2) is produced back into the atmosphere. One estimate indicates that during the active growing season, a healthy lawn area of 25 square feet will provide enough O2 for one adult person for one day2. Therefore, our green plants, including lawns, through the process of photosynthesis, contribute to a reduction in atmospheric CO2 while giving back O2.

Lawn areas alone and in combination with other landscape plants contribute to reductions in noise levels by absorbing, deflecting, reflecting, and refracting the various sounds Likewise, reductions in discomforting glare and light reflection have been noted as a positive benefit of lawn and landscape plantings4.
