Spanning 60 sites across 4 countries and three types of land uses (intensive wheat rotations, extensive rotation and permanent grassland), the study marks a significant piece of evidence for the importance of soil biodiversity.

Researchers found a strong link between soil biodiversity and the performance of ecosystems, in particular on carbon and nitrogen cycling. Indeed soil biodiversity was a…
