In Case your ever playing a trivia game and need to know the answers:)
· Grass plants are 75 - 80% water, by weight.
· Up to 90% of the weight of a grass plant is in its roots.
· Grass clippings are approximately 90% water, by weight.
· 1,000 sq. ft. of lawn will generate 200 pounds of clippings annually ... one ton of clippings will contribute only 200 pounds of decayable fiberous matter to a landfill. (Unlike a 200 pound appliance - taking centuries to decay.)
· Clippings contain nutrients useable to the grass, when left on the lawn.
Fetilizer content of typical grass clippings (by percent of weight)
- Nitrogen (N) = 4%
- Potassium (P) = 2%
- Phosphorus (K) = 0.5%
· A dense lawn is six times more effective than a wheat field and four times better then a hayfield at absorbing rainfall.
· Sodded lawns are 15 times more effective in controlling runoff than seeded lawns, even after three years of management.
· Sediment loss from sodded areas is 8 to 15 times less than for tested man-made erosion control materials and 10 times less than for straw covered areas.
· Runoff from a sodded area took 28 to 46 times longer than for any of five tested erosion control materials.
· A 50 by 50 foot lawn (2,500 square feet) releases enough oxygen for a family of four, while absorbing carbon dioxide, hydrogen floride, perosyacetyle nitrate.
· In a well maintained, thick 10,000 square foot lawn there will be:
- 6 turf plants per square inch - 387 miles of roots per grass plant
- 850 turf plants per square foot - 3 billion miles of roots per average
- 8.5 million turf plants per average home lawn (which equals 15 round trips between the sun and earth)
