The aim of study was to compare of chemical properties (pH, sorption properties,
content of humus, Al+3, H+, available forms of Mg, P, K) of Brunic Arenosols (typical rusty soils)
from time of their agricultural use and after 11 years of their fallowing. Properties were
determined by methods commonly applicable in soil science. It was found that fallowed soils
contained significantly higher amount of humus than those cultivated. Fallowing period favored
the acidification of soils, but this process occurred with different intensity in soil profile,
depending on grain composition. Acidification process was associated with decrease of base
capacity (BC), cation exchange capacity (CEC) and base saturation (BS) and increase
of content of exchangeable aluminum and hydrogen forms. Fallowed soils contained a higher
content of available magnesium and phosphorus than arable soils, while amount of available
potassium was comparable.
