Summary
This study, conducted across 60 Swiss farmlands, demonstrates that organic farming systems harbour significantly more complex root fungal networks with higher connectivity compared to conventional and no-till systems. Agricultural intensification was strongly negatively associated with root fungal network complexity, with keystone taxa (predominantly arbuscular mycorrhizal fungi) being most abundant under organic management. The findings suggest that reduced agricultural intensity supports greater microbial community structure and functional diversity in the wheat root microbiome.
UK applicability
The findings are likely applicable to UK cereal production, where conventional and no-till farming are also widespread. However, UK soil conditions, climate, and farming practices may differ from Swiss contexts, requiring local validation to confirm whether similar patterns of root microbiota complexity emerge.
Key measures
Root fungal network connectivity (R² = 0.366), keystone taxa abundance, mycorrhizal colonisation rates, soil phosphorus levels, bulk density, soil pH, fungal sequence diversity
Outcomes reported
The study measured root fungal community structure and network complexity across conventional, no-till, and organic wheat farming systems using PacBio SMRT sequencing. It assessed the abundance and connectivity of keystone taxa and their association with soil properties and mycorrhizal colonisation.
