This project has three aims: (1) to compile and critically evaluate standardised earthworm field studies in order to optimise the current test design, (2) to perform a pilot earthworm field study following the improved test design, and (3) to prepare an OECD draft guidance document. After having discussed different design options within the OECD-GSIG expert group on earthworm field studies, an earthworm field study following a modified design (covering different options) was started in spring 2017 at a crop site in Southern Hesse (Germany). First results indicate a very high earthworm density at this site. The activities are performed in close co-operation with OECD, which has included this project in the work plan of the OECD test guidelines programme (Project 2.47: New test guideline on determination of effects on earthworms in field studies). By the end of 2018, a meeting of the OECD-GSIG expert group is envisaged, discussing the outcome of the fieldwork. In the beginning of 2019, OECD is expecting a first draft of the test guideline.
