Earthworm Soil Scientists

The earthworm is one of nature's top "soil scientists." The earthworm is responsible for a lot of the things that help make our soil good enough to grow healthy plants and provide us food.

Worms help to increase the amount of air and water that gets into the soil. They break down organic matter, like leaves and grass into things that plants can use. When they eat, they leave behind castings that are a very valuable type of fertilizer.

In the picture above, Glacier Park students are harvesting worm castings to be used in the garden.

Thanks to Green Team Leader, Cathy Haws
