Original Abstract
The stability of water molecular bridges (WaMB) is investigated on the ombrotrophic organic peatland type soil. The samples of the soil collected in the north part of Scotland (UK) near the city of Stornoway. The temperaturedependence of the WaMB breaking point was measured through differential scanning calorimetry and shows how muchare the organic structures inside the peat type soil susceptible to drying. The deeper peatland soil in this work showsmuch lower temperature values of WaMB breaking of around T* ~ 47 °C compared to the top layer where the middletemperature of WaMB breakage is T* ~ 58 °C, comparable to regular soil types. This temperature dependence showshigher susceptibility of the studied peal soil for drying and therefore higher sensitivity to changes in the water table levels and disturbance of the top layers of the soil system.
