abstract = {This study compares data statistically that were collected
from both long‐term drained and undrained plots to test
hypotheses concerning the effect of drainage on plant
community, soil total nitrogen (TN), soil total carbon (TC)
and stable isotopic (δ15N, δ13C) contents in a permanent
grassland. In addition, the effects of soil depth,
topography (elevation, slope, aspect and compound
topographic index (CTI)) and spatial autocorrelation were
taken into account. Data were collected in 2010 at Rowden
Moor, North Wyke, Devon, UK, where, for the plots of this
study, subsurface drainage was introduced in 1987. The
results of a set of six linear mixed models showed that: (i)
plant community did not depend on drainage, but on elevation
and spatial effects, (ii) both TN and TC not only depended
on drainage, but also topography and sample depth, (iii) the
TC to TN ratio did not depend on drainage, but on elevation,
CTI and sample depth only, (iv) δ15N values did not depend
on drainage, but on topography and sample depth and (v)
δ13C values depended on drainage together with topography
and sample depth. Thus, drainage represented a significant
effect for only TN, TC and δ13C. Furthermore, changes in
soil physicochemical conditions, following the introduction
of drainage in the clay soil 24 years previously, induced a
shift in the plant community from a Lolium perenne L.
dominated grassland with numerous patches of Juncus species,
towards one with Lolium perenne and Trifolium repens L.},
