Long-term agricultural management impacts arbuscular mycorrhizal fungi more than short-term experimental drought

Agricultural management practices and extreme weather events associated with climate change can influence the diversity abundance of arbuscular mycorrhizal fungi (AMF) potential consequences for crop production. However, importance interactive effects long-term agricultural on AMF communities in soils is not yet fully explored. A short-term drought experiment rainout-shelters was performed winter wheat fields a trial organic (biodynamic) conventional practices. During four months growing period (March–June 2017), reduced ambient precipitation by 65% average. At two sampling dates, community composition were assessed using single-molecule real-time (SMRT) DNA sequencing. total 955 amplicon sequence variants (ASVs), belonging to twelve genera identified. The farming systems experimental did affect ASV levels. at genus level differed between systems, but no distinctive found response drought. three most abundant Acaulospora , Paraglomus Funneliformis correlated Our study demonstrates that are responsive resistant one summer event. • Organic displayed similar harboured distinct communities. No effect detected.
