abstract = {Fairy rings promoting circular greening belts in the
vegetation can shape soil microbial communities by altering
soil conditions. Knowledge about soil variables involved in
this process is incomplete. We characterised the soil
microbial communities of six fairy rings in a montane
grassland using phospholipid fatty acid (PLFA) profiling,
and studied if changes in soil properties corresponded to
changes in soil microbial PLFA patterns. Exchangeable
potassium (K) decreased inside the current rings, while soil
moisture increased in the zones where the greening belts
were two years before sampling (R2015). Fairy ring
associated changes in PLFA composition were highly related
to soil K. Gram-negative bacteria were associated with the
zones outside the ring with the highest K content, whereas
Gram-positive bacteria proportions increased inside the
ring-affected zones. An environmental stress indicator, the
iso to anteiso ratio of PLFA 17:0, decreased in the R2015
zones, coinciding with the highest soil moisture contents.
Our findings highlight the unreported importance of soil K
in fairy ring dynamics affecting microbial communities. This
common omission could lead to inc},
