Earthworms are an indicator of biological life in the soil, large and small. Easily visible and easy to count, higher numbers can be an indicator of improved soil health.

The Earthworm Index is a report on the Soilmentor web app which calculates an average wormcount per land management type, and compares your results to UK benchmarks for earthworm activity. You can also track your earthworm count per field over time, displayed automatically in accessible graphs.
