Plant available cadmium and nickel affected with chelating agents and bioinoculates after harvest of indian mustard (brassica species) in soils

Popis výsledku v původním jazyce

Soil is the most basic of all natural resources, is finite non-renewable, being misused as a dumping ground for toxic by-products rich in heavy metals. Heavy metal pollution of soil in all over the world is an alarming and catastrophic situation requiring urgent rejuvenation and decontamination. This has forced the researchers to think of using plants for cleaning of their own support system. «Phytoremediation»; which describes a system wherein plants in association with soil organisms can remove or transform contaminants into harmless and often valuable forms. Laboratory and screen house studies were carried out to evaluate the effect of chelating agent (EDTA @ 2 mmol kg-1 (5 split doses), FYM, vermicompost and microbial inoculants (Azotobacter and Pseudomonas, Bio-mix) on postharvest plant available (DTPA-extractable Cd and Ni) in contaminated sandy loam soils after Indian mustard cop species at Department of Soil Sciences, CCS, Haryana Agricultural University, Hisar, India. The results revealed that post- harvest DTPA extractable Cd and Ni in soil were low in the treatments EDTA and EDTA with microbial inoculants as the plant availability of these metals were increased by EDTA and microbial inoculants to the growing plants, thereby increasing concentration in plant biomass, remains low amounts of Cd and Ni in soils. Additions of chelating agents have been reported to increase Cd and Ni contents in the solution phase, hence, higher extractability of Cd and Ni due to chelating agents may lead to their increased availability to plants and left-over minimum metals in soil.
