The cumulation of cadmium in plants cultivated on contaminated soil
2000
Miklovic, D.
In the cultivation of oats, rye and silage maize on the strong contaminated soil by cadmium in three treatments of NPK fertilizers we have come to this conclusions: The content of cadmium was not influenced by the different dosage of fertilizers. Through the time of the experiment its content was stable and it exceeded the accepted norm about 17 times. The tissue of all three plants had ever limited content of cadmium. In the oats the differences in the content of cadmium between the treatments of fertilization were not in the level of importance both in the grain and straw. If considered the fertilized treatments the grain of rye had smaller content of cadmium than not fertilized control. The biggest cumulation of cadmium had the straw of the oats (the average about 75% from its content in the soil), smaller cumulation had the grain of rye (average 6.8%). It has documented the species specificity in the uptake of cadmium. From the hygienic point of view if cultivated plants on the strong contaminated soil we can consider these plants as dangerous
