Objective : Participants learn about the benefits of using worms
The importance of worms in healthy soils
Many worms in the soil show that the soil is a healthy living environment.
How worms help create and maintain healthy soil:
- Worms eat and cast out soil. As the soil passes through their body, the humus in
the soil is changed into nutrients and the quality of the soil improves. - Worms continuously:
- Turn humus into nutrients that plants can use.
- Dig and add air to the soil.
- Improve soil structure and water drainage.
- Bring up nutrients from deep in the soil to supply plant roots with food.
Worms are extremely economic:
- 1 worm can eat and cast out many tons of soil each year.
- 1 worm can produce 150 baby worms each year.
The facilitator can encourage a discussion with the participants to identify:
- The importance of worms in soil and how they help create healthy soil.
- How worms turn natural fertilizers (mulch, compost, liquid fertilizer, etc) into
nutrients available for plants. - Why pesticides, herbicides, and some chemical fertilizers can kill worms in the
soil.
Making a worm farm can quickly increase the number of worms in your soil. See the next
page for details on how to make a worm farm.
