Title

Drought has short-term effects on soil fungal communities leading to long-term effects on soil functions

S.E. Hannula; G.F. Veen Soil Biology and Biochemistry 2025. doi:10.1016/j.soilbio.2025.109893

Other claims from this paper (9)

Association The magnitude of the drought effect on soil fungi depended on the initial community.
Intervention effect Drought was associated with a decrease in soil fungal network connectivity.
Intervention effect Drought changed the dominant fungal taxa in soil.
Intervention effect Drought legacy reduced crop yield during the recovery period.
Intervention effect Drought legacy slowed soil decomposition rate 6 months after the drought.
Association The effect of drought on crop yield depended on the soil inoculum.
Intervention effect The legacy effect of drought on fungal communities was smaller in bulk soil than in rhizosphere soil.
Association Soil communities that were more diverse and fungal-rich recovered faster from drought.
Recommendation The authors conclude that watering of soils can alleviate the most acute drought stress on soil fungal communities.
