The standard Earthworm Watch survey compares earthworms and soils in two different areas to help us understand how human activities are affecting earthworms and their habitats. If you haven’t completed the Earthworm Watch survey so far, please take part here. With the data you gather, scientists will gain new knowledge of the role of earthworms in improving soil health.
The Earthworm Watch experiment is our next challenge and involves making special changes to one of your sites and measure the impact that this has on earthworms.
You will need about 400g (four handfuls) of vegetable peelings. Find an area in your allotment or vegetable patch large enough to measure out two squares 50 cm x 50 cm spaced at least 3 m apart, if possible.
Choose one of the squares to add the peelings to. Leave one square as it is and spread the vegetable peelings evenly over the other. Leave for a month and then you are ready to complete the survey.
