| Popis: | The influence of substances containing biogenic elements (potassium chloride, sodium phosphate, ammonium nitrate, potassium and urea nitrate) on phytoextraction degree of cadmium from soil by cultivated oat (Avena sativa L.), cutting lettuce (Lactuca sativa L.) and charlock (Sinapis arvensis L.) has been investigated. As the results of experiment the factors used for estimation of relationship between the environment and a physiological role of a chemical element, and also for revealing of its share in biotic turnover and of a role of organisms-indicators and organisms-concentrators have been calculated: phytotoxic effect and factor of biological absorbing of cadmium by plants. It is shown that potassium nitrate promote the extraction of cadmium from soil in a greater degree in comparison with other substances containing biogenic elements. |
