Biodiversity and soil type modulate the effect of plastic contamination on soil functioning
Journal of Applied Ecology, Volume 63, Issue 4, April 2026.Our findings show that the negative effects of plastic contamination on soil functioning strongly depend on soil type and can be partly alleviated by plant diversity. In sandy soils, diverse plant communities buffered functional losses under plastic stress, whereas in clayey soils the benefits of diversity were suppressed.
