Opis:: The total content and relationships between macroelements (Ca, Mg, K, Na, Mn, Fe and Al) and soil properties along the soil catena in the hilly valley of Lier River, S Norway, are discussed in the paper. The upper and middle part of the Lier River valley is covered with Stagnic Phaeozems formed from silt loam and sandy loam. In some parts of middle slope, Haplic Phaeozems (Anocolluvic) formed from silt loam and sandy loam occurred. The flat areas in the lower part of slope were covered with Mollic Gleysols formed from silt and silt loam. The average total amounts of macroelements were not high: Ca – 4.04g kg -1, Mg – 4.34g kg -1, K – 4.31 g kg -1, Na – 0.53 g kg -1, Fe – 19.05 g kg -1, Mn – 0.32 g kg -1 and Al – 20.22 g kg -1. These total amounts showed little vertical and horizontal variance in the soil profiles. The principal component analysis showed that the total amounts of elements in analysed soils was dependent mainly on sand and silt, and the similarity of soil horizons, in the cluster analysis, proves the translocation of macroelements was probable.

Opis:: An attempt has been made to identify the chemical processes that control the hydrochemistry of groundwater in the catena of Retisols/Luvisols and Gleysols/Phaeozems within the Opalenica Plain, central Poland. Groundwater samples were collected from 6 representative piezometers. The quantity of dissolved components in groundwater was connected with the location of piezometers in the relief studied and the properties of the soil’s parent materials. The groundwater of soil located higher in the soil catena was characterised by smaller concentrations of the components when compared with the composition of water from the lowest sites on the slope. The dominant hydrochemical facies are Ca,Mg–HCO3,SO4, Ca,Mg-mixed or Ca,Mg–HCO3 types in the groundwater from the higher part of the slope and Mg–HCO3,SO4 and Mg–HCO3 types in the water from the lower part of the catena. The chemistry of groundwater is the product of the weathering of carbonate minerals and silicate. The Ca2+/alkalinity molar ratio in the groundwater samples from piezometers located higher in the soil catena indicate that the weathering of both calcite and dolomite can occur there, while only dolomite weathering takes place in the groundwater of the catena pediment. The Ca2+/Mg2+ molar ratio in the water samples from the footslope shows an excess of magnesium over calcium, which could be a result of water interacting with Mg-rich silicate minerals, as an additional process to dissolution of dolomite. Furthermore, data for a few water samples from the footslope cover the evaporation zone of the Gibbs plot. This suggests that while contamination could affect the amount of dissolved components, evaporation can modify the groundwater chemistry of footslope. Cluster analysis grouped groundwater samples into two groups with similar characteristics, indicating the influence of the location of a piezometer in the soil catena on the groundwater chemistry.

Opis:: The research was carried out on a soil catena sequence, in three sections of river valleys: the Liwna and Guber rivers flowing through landscapes shaped by ice-dammed lakes on Sępopol Lowland, and the Łyna river in the morainic landscape of Olsztyn Lakeland. Along transects, from the upland edge towards the river bed, soil exposures were made, soil samples were collected, and the soil reaction, cation exchange capacity, content of organic carbon and total content of Ca, Fe, Mg, K, P, Na, Mn, Zn and Cu were analyzed. The soils of the landscape of ice-dammed lake origin contained more elements than the ones in the morainic landscape. In the catena, the highest cation exchange capacity and the highest content of macro- and microelements were determined in Histosols and Fluvisols. Among the studied Fluvisols, the highest content of Ca (19.5 g kg-1), Mg (12.60 g kg-1), Fe (41.92 g kg-1), Mn (691.38 mg kg-1) was found in the soils of the Guber catena, and the highest content of K (13.00 g kg-1), Na (0.60 g kg-1), P (3.20 g kg-1), Cu (55.90 mg kg-1), Zn (271.46 mg kg-1) was in the soils of the Liwna catena. The amounts of the elements (except Fe and Mn) were statistically positively significantly correlated with the amount of organic carbon as well as the silt fraction 0.05-0.002 mm (all elements) and clay fraction <0.002 mm (Ca, K, Na, Fe, Mn). Fluvisols and Histosols in river valleys, owing to their high accumulation capacity, play a very important role in the circulation of elements and strengthen the resistance of landscapes of ice-dammed lake origin and morainic hills to human activity.
