Vineyard-living microbiota affect grapevine health and adaptation to changing environments
and determine the biological quality of soils that strongly influence wine quality. However,
their abundance and interactions may be affected by vineyard management. The present study was
conducted to assess whether the vineyard soil microbiome was altered by the use of biostimulants
(arbuscular mycorrhizal fungi (AMF) inoculation vs. non-inoculated) and/or irrigation management
(fully irrigated vs. half irrigated). Bacterial and fungal communities in vineyard soils were shaped
by both time course and soil management (i.e., the use of biostimulants and irrigation). Regarding
alpha diversity, fungal communities were more responsive to treatments, whereas changes in beta
diversity were mainly recorded in the bacterial communities. Edaphic factors rarely influence bacterial
and fungal communities. Microbial network analyses suggested that the bacterial associations
were weaker than the fungal ones under half irrigation and that the inoculation with AMF led to
the increase in positive associations between vineyard-soil-living microbes. Altogether, the results
highlight the need for more studies on the effect of management practices, especially the addition
of AMF on cropping systems, to fully understand the factors that drive their variability, strengthen
beneficial microbial networks, and achieve better soil quality, which will improve crop performance. [--]
