Article Synopsis
- Soil health is critical for plant growth and ecosystem health, yet its relationship with primary productivity across different environments isn't well understood.
- A large study across 588 sites in 27 European countries revealed that woodland soils are significantly healthier than those in grasslands and croplands.
- The research found that soil biodiversity, particularly certain microbial groups like nitrogen-fixing bacteria and mycorrhizal fungi, plays a vital role in enhancing primary productivity, highlighting the importance of maintaining healthy soils for agricultural and ecological success.
Evaluation of the ecological risk of pesticide residues from the European LUCAS Soil monitoring 2018 survey.

Article Synopsis
- The 2018 LUCAS Soil Pesticides survey assessed 118 pesticide residues at over 3,473 sites in the EU to create risk-based indicators for pesticides in the environment.
- Two mixture risk indicators were established based on toxicity data, with 74.5% of sites containing detectable pesticide levels, and key contributors to risk identified as imidacloprid, chlorpyrifos, and epoxiconazole.
- The survey will inform future research and evaluate the effectiveness of pesticide regulation efforts aimed at reducing environmental risk, particularly concerning soil health and biodiversity.
Factors regulating the diversity and composition of soil microbial communities include soil properties, land cover and climate. How these factors interact at large scale remains poorly investigated. Here, we used an extensive dataset including 715 locations from 24 European countries to investigate the interactive effects of climatic region, land cover and pH on soil bacteria and fungi.

We analysed microbial biodiversity metrics and distribution of potential functional groups along a gradient of increasing land-use perturbation, detecting over 79,000 bacterial and 25,000 fungal OTUs in 715 sites across 24 European countries. We found the lowest bacterial and fungal diversity in less-disturbed environments (woodlands) compared to grasslands and highly-disturbed environments (croplands).

However, soil biodiversity is currently threatened by land-use intensification, and a mechanistic understanding of how soil biodiversity loss interacts with the myriad of intensification elements (e.g.
