The content of total calcium in particular granulometric fractions is in most cases not correlated with particle size. In soil developed from boulder loam, total Ca content in the analyzed grain sizes increases with depth due to the presence of CaCO₃ below 100 cm. In turn, in soil developed from old-alluvial deposits, in which CaCO₃ was not noted, Ca content does not reveal any regularity in the particular fractions. The total calcium content in particular fractions depends on the leaching process and the origin and properties of the parent rock.
