The dynamics of exchangeable cations in the environment of soils at Kampinoski National Park

A set of physico-chemical properties of soils: soil pH, hydrolytic acidity, alkaline exchangeable cations, cation exchangeable capacity (CEC), and base saturation were studied in six-year long investigations of ecto-humus (organic layer) and endo-humus (Ah horizon) horizons of forest soils at the Kampinoski National Park in Poland. The soil properties determined in the present study showed differentiated values, depending on the actual horizon, the type and degree of soil development advancement, the genesis of the soil parent material (bedrock) as well as on the development of plant community prevailing in given site.
