Described experiment was founded in outside dumps of the former lignite mine "Friendship of Nations", near Łęknica. Two test objects of different ages of the Scots pine at the start (2 and 6 years old) have been founded, within the plots constructed with differentiated mineral fertilization. During the technical reclamation trace elements have been introduced to grounds with the waste lime from Zinc Smelter in Miasteczko Śląskie. After 24 years there has been a low content of trace elements in grounds reported – subtotal form: 2–209 (av. 35) mg Zn · kg–1, 0.2–58.7 (av. 5.0) mg Cu · kg–1, form determined in 0.1M HCl: 0.1–106.0 (av. 14.7) mg Zn · kg–1, 0.1–7,9 (av. 1.0) mg Cu · kg–1. The content of Cu and Zn showed a dependence on the depth of sampling. Regardless of the type of fertilization, higher levels of the two determined forms of copper and zinc were found in the forest litter. With the increasing depth of sampling it has been indicated very clearly decrease of the both forms of Cu and Zn content. Participation of form marked in 0.1 M HCl in a subtotal form was varied (Zn: 1.1–91.7%, Cu: 1.1–78.0%), but often exceeded 50%. This corresponded with a very strong acidity of post- -mining grounds on presented areas.plUznanie autorstwa-Użycie niekomercyjne 3.0 Polskacynk w glebachmiedź w glebachrekultywacja leśnaCu in soilsforest reclamationZN in soilsDyscyplina::Nauki leśneArticle2300-5378
