Effects of conventional and biodegradable microplastics on soil invertebrate communities in PAPILLONS field plot experiment in Finland, Germany and Spain

Data on soil invertebrate communities at PAPILLONS field plot experiment sites in Finland (Natural Resources Institute Finland and Finnish Environment Institute), Germany (University of Bonn) and Spain (IMDEA Water), sampled in autumn 2022 and 2023. At all three study sites, five treatments with five replicate plots were established in spring 2022: control with no microplastic addition, and two nominal concentrations (0.005%, 0.05%) of conventional polyethene (PE) and blend of starch and polybutylene adipate terephthalate (PBAT) microplastics. Microarthropods and earthworms from Spain and Germany were analysed at the Vrije Universiteit Amsterdam and part of the earthworms and enchytraeids at Finnish Environment Institute. eDNA data (Natural Resources Institute Finland) on microfauna has been saved in another data repository.
