摘要

The content of the total calcium was studied in granulometric fractions of the following diameters: <0.002, 0.005-0.002, 0.02-0.005, 0.05-0.02, 0.1-0.05 and 1.0-0.1 mm. It was observed that the amount of Ca accumulated in particular fractions is not correlated with their content in soils. The ratios of Ca content in a given fraction to the content of the granulometric fraction (Ca/Fr) keep gradually decreasing from a clay fraction <0.002 to a sandy fraction of 0.1-1 mm. No calcium migration from the surface of the studied soils down the profile was observed in particular fractions, except for the clay fraction <0.002 mm in lessive soil profiles.
