The effects of glucose and cadmium addition, as well as their combination on the CO2 efflux from soils, which differed by the total organic carbon content and texture, were studied. Glucose (10 g/kg) addition induced an increase in the CO2 efflux from soil and a decrease in the content of dissolved organic carbon. The intensity of this effect reduced in samples with the low total organic carbon content. Cadmium (300 mg/kg) addition alone did not affect the studied parameters. In case of
