Toksyczność glinu (Al) w glebach leśnych

The paper presents resent research results on the effect of aluminium (Al) toxicity on forest soils. It has been stated that with the present acidification level of the environment the toxic effect of aluminium compounds does not threaten the sustainability of stands. At the same time, the simulation of heavy acidification of soil environment has proved that mixed stands are more resistant to Al than pure spruce stands growing under the same conditions.
