Claim · model-written summary
Drought reduced soil fungal biomass and diversity relative to irrigated controls in mesocosms.
Verbatim
e1“We show that drought has an direct negative effect on soil fungal biomass and diversity and that the magnitude of the effect depended on the initial community in soils”
e2“In a fully factorial design, half of the mesocosms were subjected to severe summer drought while half served as irrigated controls”
e4“the effects of drought legacy are apparent as reduction of crop yield in recovery period and slower decomposition rate 6 months after the drought”

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.
