Thesis aims to define determination of particle size distributions loamy and sandy soils measured by two methods of measurement: laser granulometry and pipette method and comparison of measured results. First part of thesis is focused on theoretical comparison of two methods of measurements, predominantly on potential problems connecting with their comparing and suitable setting of device parameters to obtain accurate results. Comparison between laser granulometry and pipette method was carried out for 90 loamy and 30 sandy soil samples. Analyzed samples were measured using a Malvern Mastersizer 2000. Comparison of laser granulometry and pipette methods demonstrated differences of results, which were different for the various samples. Despite the variance of the measured results, was found for the clay fraction the correlation 0, 92 between methods for loamy soils, for sandy soils was found the correlation of 0.90 for the sand fraction.
