Abstract: Soil acidification is one of the major factors of soil degradation as it disturbs the functioning of soil ecosystems, increases toxic mobile aluminium, results in reduced soil productivity. It depends on the environmental conditions as well as soil genesis. For the Western Lithuania the genetic properties of soils (depth to the carbonates is 1.5-3 m) and soil leaching regime due to rainfall surplus is common resulting in leaching of the bases cations (Ca2+, Mg2+) and natural soil acidification. Therefore soils in that region are very sensitive to the acidification and requires for the periodic liming. Moreover the big intervals between liming procedures increses soil acidity even more. In the period of 1997 when liming was performed the last time to 2007 years the area of acid soils in Western Lithuania increased by 8.5%. In 2011 year there were 36.5% of acid soils (pHKCl<5.5) in that region. Therefore the need of liming of soils in Western Lithuania is of great importance. The question is just what liming materials are more effective and what reccomendations of soil acidity management should be. In order to investigate effectiveness of calcereous liming materials two experimental plots of Albeluvisols of different acidity (Eutric pHKCl 4.27 and Dystric 5.82) had been instaled, each plot was divided into 5 subplots, and each subplot in area of 50 m2 was limed with different liming materials of local origin (chalk, „agrokalkės” (limestone and lime powder), crushed dolomite „Dirvitas“, and “kalktrąšė“(pel-lime, pelleted liming material). Experiment was performed randomly in four replicates and also control subplots without any liming were instaled in each replicate of the experimental plot. Soil pHKCl was monitored for 18 months and liming efficiency of materials used on soil potential acidity and Al mobility was evaluated
