Take the earthworm quiz!


#1

A quiz created by Jackie Stroud, soil scientist at Rothamsted Research, also known as ‘The Worm Lady’

Did you know there are three different types of earthworms at work in your soil? Each type lives in a specific layer and performs a unique function which contributes to the soil’s health.

It’s simple to monitor the activity of earthworms, all you need to do is dig a 20cm deep hole in the ground and count the different earthworms you find in each layer. Counting the number of worms is a good indicator of life in the soil. If you go one step further and identify what type of worm it is, then this can tell you much more about what the worms are working on and help uncover any necessary changes you need to make in your soil management.

Really you want to have all three types of worms working in harmony. The living litter feeders break down organic matter on the surface of the soil, the top-soil worms work on soil aggregation and nutrient mobilisation, and then the deep-burrowers keep water flowing from the soil surface to deep pools below, as well as increasing aeration and root development.

However, you need to make sure you can identify which worms are which before you head out to the field! Jackie has created a fun and fantastic quiz to help you learn about and test yourself on different worm types.

It only takes a few minutes to complete and you’ll learn everything you need to know about earthworms from the surface dwellers to the deep burrowers.
