Abstract

Heavy metals in soil are linked to fertilizers, both organic and inorganic. Phosphorus in fertilizers adds a lot of Heavy metals to the concentration of Toxic metals (point source). Phosphate pebbles, a byproduct of phosphorus fertilizers that are insoluble in water, are crucial in the process of metal immobilization in soil by precipitation as metal phosphates. Mineral nutrients are needed for plant development and production, and there are a number of these elements. For example, copper, zinc, iron, manganese, molybdenum, nickel, magnesium, calcium, and boron can facilitate: sugar metabolism, nitrogen fixations, respiration, enzyme activity, gene control, pigment production, photosynthesis, ion homeostasis and other cellular processes inside of the plant at minimal levels. Nonetheless, these critical elements have a detrimental effect on the development, growth and reproduction of plants at levels above acceptable limits. The altered physiological and biochemical processes that cause decreased plant development are one of the key indicators of heavy metal poisoning. To protect agricultural and human health, as well as save current resources, it is very important to remove heavy metals from polluted soils. Phytoremediation is generally mentioned as one of the best ways to get rid of heavy metals from contaminated soils. Phytoremediation and rhizo filtration methods may get rid of heavy metals and other contaminants in unclean soil and water.
