In the present paper arable soils of the Upper Silesia were evaluated as to copper. zinc, manganese and iron contents, determined in the same extract, i.e. 1 M dm–3 HCI. The studies comprised 20 points in the vicinity of Sosnowiec and 20 points from near Zawiercie. Soil abundance in the available forms of microelements was assessed on the basis of the limiting numbers suggested by the Institute of Soil Science and Plant Cultivation. Soils of Zawiercie and Sosnowiec belonged to those with high contents of zinc in all the cases; in the majority of objects these were the soils with medium contents of copper and manganese. In half of the cases, the soils were classi1ied as possessing low iron content, and in the remaining half as having medium iron content.
