Major Contribution: Improving soil.

Earthworms may very well be the gardener’s best friend. They burrow into the ground, creating small narrow hole. These holes allow air and water to easily reach plant roots. As they dig, they also leave excrement behind which serves as a powerful fertilizer. These fascinating animals are, in fact, more helpful than any man-made fertilizer.

They are the world’s first gardeners, and the more earthworms in soil the healthier the soil will be. Studies have compared soil “invested” with earthworms to those with none, and study after study shows the earthworms create more productive soil, helping our soil and our lives.
