The purpose of this study was to determine the effect of increased soil moisture levels on
the decomposition processes in a peat-extracted bog. Field experiments, in which soil
moisture levels were manipulated, were conducted using 320 microcosms in the
Wainfleet Bog from May 2002 to November 2004. Decomposition was measured using
litter bags and monitoring the abundance of macro invertebrate decomposers known as
Collembola. Litter bags containing wooden toothpicks (n=2240), filter paper (n=480)
and Betula pendula leaves (n=40) were buried in the soil and removed at regular time
intervals up to one year. The results of the litter bag studies demonstrated a significant
reduction of the decomposition of toothpicks (p<0.001), filter paper (p<0.001), and
Betula pendula leaves (p
