%0 Research Notes %T Decomposition of cellulose in the peat of some pine bogs and fens %A Tuominen, Liisa %D 1981 %J Suo - Mires and peat %V 32 %N 4-5 %U http://suo.fi/article/9540 %X Cellulose decomposition rates and the vertical distribution of the activity of decomposers were studied during one year in the mires Heinisuo and Kaurasten-suo in the following mire site types: LuSN, TuSN, LkN, KR, RaR, TR, NR and RhNR. The most important factor controlling the decomposition was oxygen availability due to the ground water table and its stability. Another important factor was the temperature, as was seen when comparing the results of the summer and the winter observations. In some cases the decomposition activity depended on the trophic level of the mire site type, for example in the hollows of RaR, TR, NR, and RhNR.
