Impact of nitrogen and phosphorus addition on resident soil and root mycobiomes in beech forests

The aim of the study was to investigate the influence of fertilizers on
root-associated and soil residing fungi in beech forests. We report data
from a fertilization experiment in three temperate beech forest with
contrasting soil phosphorus concentrations. We used soil cores and the
fractions of the organic layer and mineral topsoil separately of spring
and fall 2018. We collected bulk soil and roots. We provide data on soil
for pH, mineral elements, ammonium, nitrate, carbon, nitrogen. We provide
data on root mineral nutrients, carbon and nitrogen. Illumina sequencing
in soil and roots provides fungal amplicon sequence variant (ASV) and
morphotyping of beech fine roots the active colonizing ectomycorrhizal
fungi, including diversity parameters.
