Grass plants are 70 to 80% water and clippings are 90% water
90% of the weight of grass is in its roots
A 10,000 square foot lawn will contain: 6 grass plants per square inch, 850 plants per
square foot, 8.5 million plants total
The front lawns of 8 average houses have the same
cooling effect as 24 (3-4 ton capacity) home central air conditioning units
Turfgrasses trap much of an estimated 12 million tons of dust and dirt released annually
into the U.S. atmosphere.
Turfgrasses help purify water entering underground aquifers
by its root mass and soil microbes acting as a filter to capture and breakdown many types
of pollutants.
A dense lawn is 6 times more effective than a wheat field and 4 times
better than a hayfield at absorbing rainfall.
A 50 by 50 foot turfgrass lawn (2,500 square feet) releases enough
oxygen for a family of four, while absorbing carbon dioxide, hydrogen fluoride and
perosyacetyle nitrate.
The grass and trees along the U.S. interstate highway system
release enough oxygen to support 22 million people.
