The Cd content of glutinous (Oryza sativa L.) and non-glutinous-rice (Oryza sativa, glutican) treated with CdS, an insoluble salt increased with the Cd content of soil, but the cadmium uptake was lower than in the case of CdO. Cadmium induced metal element deficiencies in rice plants, which were associated with the phenomenon of chlorosis and were alleviated with the application of calcium carbonate at an early stage of rice growth. The Cd content of both variations of rice significantly decreased by the addition of CaCO3. The Zn and Fe contents of plants decreased with the increase in the Cd content of soil
