Grass is an important and critical part of nature, enriching and strengthening the soil and helping to restore important nutrients. Beneath the surface, your lawn is teeming with life.
Of the creatures you can see with the naked eye, earthworms are probably the most prominent, and their presence signals the healthiness of the soil. Earthworms improve the soil's aeration just by crawling through the dirt, creating passages for air and water. They eat their weight in organic material, which they excrete in the form of nutrient-rich casts. Lawns provide much of the organic material they need. Worms also play a crucial role in the food chain, serving as dinner for many species of birds and insects.
Lawns are home to beneficial insects, and provide a feeding ground for birds and other animals. Good bugs and organisms that thrive in healthy lawns act as pollinators for many plants. And rich lawn soils contain trillions of microorganisms. These tiny creatures eat and break down nature's leftovers from decomposing grass clippings and other organic matter to further enrich the soil. It's all a part of nature's cycle.
Adding organic matter is one of the best ways to improve your soil, and your lawn does it naturally. By sloughing off roots, stems, and leaves as part of the natural growth process, grasses add large amounts of organic matter to the soil returning nutrients back to grass.
Feeding your grass regularly with a lawn food such as Scotts® Turf Builder® Lawn Food helps it grow strong and better able to build organic matter in the soil. You can also recycle nutrients back into the soil for extra nourishment by leaving grass clippings on your lawn after mowing.
