The slag from examined waste damps contains small amounts of macroelements, relatively high quantities of available iron, nickel and chromium, exhibits and alkaline reaction and low water capacity. Biological analyses demonstrated that symbiotic and asymbiotic nitrogen-fixing bacteria, as well as some papilionaceous species (Pisum sativum L., Lupinus luteus L., Sarothamnus scoparius L.) and some grasses (Bromus sterilis L., nad Bromus inermis Leyss.), find favorable conditions for development on this slag. The experiments indicate that the main factors delimiting plants growth and development on the slag are: lack of available nitrogen, excess of iron, nickel and chromium, and the dry dust layer forming on the slag surface
