In conditions of vegetative tank experiment was followed the effect of calcareous-magnesite dross with chromium content on chemical properties of acid cambisol and on content of twelve elements (P, K, Ca, Mg, Na, Fe, Mn, Zn, Cu, Pb, Cd, Co) in the soil and two tested crops (winter wheat, soybean). It was determined, that applied dross propitiously affected the soil pH, exchangeable basic cations (especially Ca and Mg) and degree of sorptive saturation in investigate sample, which was reflected on biomass of crop. Increase of chromium in soil under the applied dross was showed only on winter wheat straw. Neutralization of acid soil was expressively reflected in increase of available phosphorus and in decrease of available manganese and zinc in soil. These changes was manifested also on tested plants
