The aim of the research was to assess the uptake and use of trace elements from municipal sewage sludge by the multiflora rose (Rosa multiflora Thunb. ex Murr) cultivar Jatar and Virginia fanpetals (Sida hermaphrodita Rusby). A six-year field experiment involved four levels of fertilization with sewage sludge at doses of 0, 10, 20, 40, 60 Mg DM ha-1. The sewage sludge was applied once before planting energy crops. Due to the low potassium content in the sewage sludge, supplemental potassium fertilization (100 kg K ha-1 in the form of 40% potash salt KCl) was applied once on all plots. Fertilization with nitrogen, phosphorus and with microelements was not performed during the crop cultivation. The research evaluated the size of yields, and the content, uptake and utilization of Al, Mn, Fe, Co and Mo from municipal sewage sludge by energy crops. It was established that increasing doses of sewage sludge significantly increased the yield of multiflora rose and Virginia fanpetals biomass. The yield of Virginia fanpetals was one and a half times higher than that of multiflora rose. Increasing doses of sewage sludge significantly increased the content and uptake of Al, Mn, Fe, Co and Mo by the tested species. It was established that Virginia fanpetals had a higher content of Al, Mn, Co and Mo compared to multiflora rose. Multiflora rose had a higher content of Fe compared to Virginia fanpetals. It was determined that Virginia fanpetals took up more trace elements compared to multiflora rose. The highest trace elements’ uptake with the yield of the energy crops was observed at the dose of 60 Mg DM ha-1. The highest phytoremediation of the studied trace elements was observed at the dose of 10 Mg DM ha-1. Based on the research, it was concluded that Virginia fanpetals utilized trace elements from municipal sewage sludge more efficiently than multiflora rose.
