Total content of Al in 1M KCl extract, labile forms of Al and basic soil characteristics were determined in forest and grassland soils. The greatest differences resulted from the differences in soil cover. The content of exchangeable Al, both total and labile, was significantly higher in forest soils than in grassland soils. The content of labile Al in 1M KCl extract was in close correlation with the total exchangeable Al, the content of Al extracted by 0.05M Na4P2O7 was not significantly correlated to exchangeable forms. According to weights distribution among all variables it was possible to describe the first factor as a factor of soil reaction showing significant influence on the content of exchangeable forms of Al in soil. The second factor was described as a factor of soil organic matter.
