The aim of this paper was to show how the shape
of sand particles affects the results of particle size distribution
obtained by the laser diffraction method. On the basis of the results
obtained one can conclude: the shape of the investigated particles
influences particle size distribution obtained by the laser diffraction
method. This phenomenon occurs in the sand fraction, as shown
in our investigation. The importance of this effect depends on the
type of the measured material and on the aim of the investigations.
For most researchers in soil science and sedimentology who
investigate sand fractions, this impact can be negligible. Further
investigations with other soil and sediment fractions are needed
