Megjegyzések:	The application of various alternative nutrient supplies can partly be substituted by chemical fertilizers resulting in economical use with less environmental strains. Biofertilizers promote nutrition uptake, but still there are a lot of questions about their application under stress conditions. One of the main abiotic factors is polluted soils containing toxic elements. In the course of the intensive plant growing, considerable quantities of cation leave the soil to lead to acidification, thereby enhancing the uptake of heavy metals by plants. Cadmium (Cd) toxicity is a major problem affecting crop productivity worldwide. The presence of Cd in the rhizosphere can cause stress responses and alteration in many physiological processes, including nitrogen metabolism, photosynthesis, carbohydrate metabolism, sulphate assimilation and plant-water interactions. Cd can get into the food-chain, causing public health problems. The aim of our work was to investigate the effects of biofertilizers on plant production and nutrient uptake in the case of Cd-polluted soils. Cd accumulated primarily in the roots, transport to the shoots was rather low, but there were differences between the two investigated plants. Sunflower took up more Cd, and may have had larger stress-tolerance to Cd than maize. With the use of the bacterium-containing biofertilizer, the toxic effect of cadmium was moderated.
