Comparison Between The Efficiency of Soil and Foliar Fertilization Beside Evaluation Methods Remediation

Phytoremediation is the use of a plant`s natural ability to contain, degrade, or remove toxic chemicals and pollutants from soil or water. It can be used to clean up metals, pesticides, solvents, explosives, crude oil, and contaminants that may leak from landfill sites (called leachates). The term phytoremediation is a combination of two words: phyto, which means plant, and remediation, which means to remedy. Scientists are investigation phytoremediation`s potential by using plants such as sunflower, ragweed, cabbage and geranium, as well as other less known species. The plants are often used in combination with other traditional technologies for cleaning up contaminated sites because of the phytoremediation`s limitations. In the present work, the comparison between the efficiency of soil and foliar fertilization beside the impact of over fertilization on soil and water pollution was unvestigated in the presence of heavy metals, either originated from mineral fertilizers or supplementary added to the soil. Therefore, the objectives of the present investigation could be summarized in the following points: -To evaluate the efficiency of soil and foliar fertilization. -To evaluate the application rate of fertilizers. -To evaluate the yield response for both methods of fertilization -To identify the most accumulator plant under Egyptian condition. -To evaluate the mobility of heavy metals through soil layers.
