The impact of fine metallurgical sludge on sunflower plants was studied. Found that metallurgical sludge are highly bioactive in relation to sunflower seeds. In making the habitat of plants aqueous solution sludge by more than 30% increase in germination energy of seeds. The most significant increase in the amount of sludge in the medium affects the length and weight of vegetative parts of sunflower. Thus, at concentration of 10% root length is increased about 5 times, and the length of the stem by 2.5 times compared to the control. The results can be used in the development of microelement fertilizers based metallurgical sludge, and during activities phytoremediation metallurgical waste.
