Summary

Scientists spent two years studying how tiny plastic particles in soil affect grasslands, including their interactions with helpful fungi that plants rely on for nutrients. This matters because microplastics are building up in soils everywhere—including farmland—and understanding how they disrupt plant communities and soil health helps us grasp the bigger picture of how plastic pollution could eventually work its way into our food supply and ecosystems we depend on.

The data refers to the manuscript Speißer et al. 2026 "Interactive effects of microplastics and arbuscular mycorrhizal fungi on grassland communities" (http://doi.org/10.1002/ppp3.70229), in which we report the results of a two-year outdoor experiment, testing the effects of different types of artificial particles (glass, different microplastics) and their interactions with arbuscular mycorrhiza on two plant-community types representing species rich dry grassland and less species rich mesic grassland communities.
