Czerwinski, Z. (Warsaw Agricultural University (Poland). Dept. of Soil Science)
Natural saline sources rising in the Kujawy region in many localities are strongly mineralized with the content of dissoluble salts amounting to 3.72 g per cubic dm. In the presence of chalk and lake sediments in the sunsoil, these waters can be enriched with calcium, magnesium and sulphate compounds. The waters of saline sources are characterized by a high SAR coeficient, i.e. by a possibly intensive penetration of the N cations into the sorption complex of the soils. In the regions of appearing of these waters there are formed soils with saline horizons containing 0.1-2.0 percent of dissoluble salts of the EC electrolytic conductivity over 2 dS/m, 25 deg C and of the saturation degree of the sorption complex with the Na cations up to 15 percent
