This paper characterises S-SO4 concentration in the surface (0-20 cm) layers of the agricultural soils in Poland (45242 soil samples) and in the Lublin region (3648 soil samples). Mineral soils in Poland contain, on average, 1.79 mg of S-SO4/100 g of soil. In the Lublin region, it is 1.65 of S-S-O4/100 g of soil. In the whole of the country, 83.2% of the agricultural soils have natural (00 +10) levels...
The paper characterises total concentrations of Cd, Cu, Ni, Pb, Zn in the surface layers (0-20 cm) of agricultural soils in Poland (48620 soils samples) and Lublin region (3829 soil samples). The results for Lublin region are expressed in terms of the degree of metal pollution as compared to contamination in the rest of the country. The average concentration of Cd, Cu, Ni, Pb and Zn (in mg kg-1 of...
