The purpose of this study was to explain the reason of the FID signal intensity change for soil samples in the positive temperature range (0-40°C). According to the reference data the main cause is the presence of the paramagnetic ions in soil. The experiment conducted on 4 cohesive soils showed that the main reason of FID changing could be the change of the water’s heat of the vaporization, decreasing as the temperature increases.NMR Spectrometry method was used in the research and Statistica 9.1 software was used for statistical analysis.
