| Zusammenfassung |
| Amount and quality of produced food is highly dependent on soil chemical properties and
composition. The GEMAS project (Geochemical Mapping of Agricultural and Grazing Land
Soil of Europe) has provided new homogeneous geochemical data for Polish agricultural
soils. This study presents the distribution of common major elements such as CaO,
MgO, Fe2O3, Al2O3, K2O, Na2O, SiO2, determined in 129 samples of agricultural
soil of Poland. The total element concentrations obtained by X-ray fluorescence
spectroscopy (XRF) were compared with the results from aqua regia acid digestion
determined by ICP-MS. The distribution patterns of selected major elements reveal two
major geochemical provinces - the northern province and the southern province,
distinguished with respect to the natural geochemical background and resulting from the
geological evolution of the region. The soil of the northern province (Polish Lowland),
dominated by glacial deposits, show low contents of CaO, MgO, Fe2O3, Al2O3,
K2O, Na2O, and high contents of SiO2. High silica content reflects the presence of
sand-rich deposits which belong to the larger European feature with cover sands and
loess of mainly Weichselian age and stretching from Ukraine to western Germany
and Denmark. The southern province is characterised by high concentrations of
almost all major elements (except SiO2). Soils in the Sudetes, Upper Silesia and
the Carpathian Mountains developed in majority on pre-Quaternary rocks. In the
Sudetes, soil formed on magmatic and metamorphic rocks of Paleozoic age. In the
Carpathians and Upper Silesia, the flysch and molasse formations containing various
material of magmatic and sedimentary origin constitute the immediate substratum of
soil. |
