The material for this study was obtained from several regions of Poland, from 13 soil profiles of various geneses that include those formed from various rock types. It has been observed that the total aluminium content in the individual granulometric fractions increased as soil particle diameter decreased. Similarly, the share of individual fraction groups in the total aluminium accumulation in the soil mass increased as to particle diameter decreased. The <0.005 mm grains stored a greater share of the total aluminium than indicated by their share of the soil mass, whereas <0.02 mm grains had a smaller share of the aluminium than their share of the soil mass.
