Do earthworms make plants grow faster?
[1] Earthworms can make plants grow better, and possibly faster, by the improvements that they make to soil. They tunnel through soil, thereby opening up passageways for air, nutrients, and water. [2] They open up pore spaces for the passing of water, thereby improving waterholding and drainage in soil. [3] They eat and eliminate, thereby building up organic matter in soil. [4] They die and decay, thereby adding their body and body parts to the organic content of soil.
