Streszczenie

The influence of the soil granulation, grain diameter and the soil type on the FID signal intensity is presented. The FID signal intensity is used to determine the water content in soil sample by the use of the NMR spectrometry. Eighty five samples taken from four different soils (3 sand,1 sandy silt) were tested. The samples were characterized by different masses and water contents. The results of the FID signal intensity were compared to the mass of water in soils calculated by empirical formula obtained for clay soils and the mass of water obtained by the oven-drying method. The empirical formula using FID Signal Intensity can be used to calculate the mass of water in every soil regardless of its type. The type of soil, grain diameter and granulation do not appear to influence the FID Signal Intensity value. The factors that influence the FID Signal Intensity are the mass of water in soil, the water content in case of poorly sorted soils and the mass of soil sample in well sorted soils. The statistical analysis were conducted using Statistica 9.1 software.
