The soil temperature at depths of 20, 50 and 100 cm has been higher in the summertime in the cultivated fen soil at Leteensuo than in cultivated Sphagnum peat soil, while the latter again had higher temperatures than Sphagnum bog in its natural state. There is a remarkable difference in soil temperature between two bogs of different geographical location, namely, Leteensuo and Pelsonsuo. At Leteensuo, which lies in the southern part of Finland, the soil begins to warm up at a much earlier date than at Pelsonsuo and the soil temperature is higher. The effective soil temperature (referred to +5°C) at 20 cm depth is nearly twice as high as at Pelsonsuo; at a greater depth it is even three times as high.
