“…Also, soil pH value, soil organic matter (SOM) and electrical conductivity (EC) were signi cantly increased as in uenced by Casuarina biochar addition (Ibrahim et al, 2022). In another study, Pescatore et al (2022) observed with addition of biochar (mix of Douglas and Black Pine wood as feedstocks) at two rates (0.8 and 1.6% wt.) to a PTEs-contaminated soil, SDM of berseem clover (Trifolium alexandrinum L.) was increased while shoot PTEs concentration decreased.…”

Studies on the interaction effects of silicon (Si) and biochars in potentially toxic element (PTE)-contaminated soils are limited. Thus, the aim of this study was to investigate the interaction effects of biochars, from sheep manure (SMB) and rice husk (RHB) produced at 300 and 500 °C, and 2 levels of Si (as Na metasilicate), on growth and chemical composition of corn (Zea mays) in a Ni-polluted calcareous soil. It was found that the combined application of Si and biochars significantly reduced soil available Ni (17-32%) and the corn shoot Ni concentrations (29-58%), associated with soil pH increase (r=0.56-0.60, P<0.01). Among the biochars, SMB increased soil pH the most, and increased soil EC to saline levels, attributed to the higher ash content of SMB. Similarly, increasing Si application levels resulted in increasing soil pH and EC values. Application of all the biochars resulted in significant biomass increases with most positive effect from RHB. Despite the positive effect seen on soil Ni immobilization, the combined application of Si and biochars generally resulted in a decrease in corn shoot biomass yields compared to biochars alone, attributed to the significantly higher soil pH, EC and Na content which resulted in suppression of macro and micronutrient uptake by the corn.

“…Other metals or elements present in excess do not harm the plant's tissues or cells; in fact, their buildup may promote the plant's growth. The metals which are lethal or harmful for plants include: lead (Pb), cadmium (Cd), cobalt (Co), iron (Fe), silver (Ag), platinum (Pt), nickel (Ni), chromium (Cr), copper (Cu), and zinc (Zn) ( Pescatore et al, 2022).Both natural and human-made processes are the sources of heavy metals in the surface environment. Parent rocks and metallic minerals are examples of natural sources" [3].…”

Aim: Long-term use of sewage-sludge and improper management of agricultural lands can lead to an elevated heavy metal concentration in the soil resulting in barren soil. The present investigation was carried out to study the influence of different soil characteristics on the enrichment of Cd, Cr and Pb and their detoxification strategies in sewage irrigated soil profiles of Prayagraj region, India. Methodology: Di-acid mixture method used for soil analysis. The clean filtrate was used for the estimation of the heavy metals (Cd, Cr and Pb) by Atomic Absorption Spectrophotometer (AAS) (AAnalyst600, Perkin Elmer Inc., MA, USA). Isolation and identification of Cd, Cr and Pb Detoxifying microorganisms were isolated from the sewage-irrigated soils by nutrient agar medium. Results: It was observed that surface soils contained higher amount of DTPA- extractable heavy metals (Cd 3.00-3.20 mg kg-1,Cr 5.20-6.40 mg kg-1 and Pb 6.80-7.20 mg kg-1) and these amounts along with CEC (26.10 Cmol (p+) kg-1) and organic carbon (OC) Content (0.58%) decreased with the depth of soil profiles. Among the tested microorganisms, the highest accumulation of heavy metals in the sewage irrigated soils was observed in Citrobacter spp. to the extent of Cd 13.2%, Cr 36%, and Pb 42%. However, the lowest accumulation was observed in Escherichia coli to the extent of Cd 1.2%, Cr 8.4%, and Pb 10.2%. Conclusion: The horizons A of the studied soil profiles contain almost 12% more Cd, 9.11% more Cr, and 52% more Pb as compared to the contents of horizons B. Biological detoxification system metal uptake is largely influenced by the availability of metals. The highest accumulation of heavy metals was observed in the order of Pb > Cr > Cd by the selected microorganisms in the order of Citrobacter spp. >Bacillus spp. > Pseudomonas aerugia > Rhizopus arrhizus > Escherichia coli, resulting in the detoxification of the metals in the sewage irrigated soils.

“…Excess amounts of other metals or elements do not damage the tissues/cells of the plant, and their accumulation can even increase the growth of the plant (Ahmad et al 2022, Ali andChaudhury 2016). The metals which are lethal or harmful for plants include: lead (Pb), cadmium (Cd), cobalt (Co), iron (Fe), silver (Ag), platinum (Pt), nickel (Ni), chromium (Cr), copper (Cu), and zinc (Zn) (Chen and Lu 2018;Pescatore et al 2022). Agricultural soil is befouled by many heavy metals, which is a major issue.…”

Contamination of agricultural soils with heavy metals present lethal consequences in terms of diverse ecological and environmental problems that entail entry of metal in food chain, soil deterioration, plant growth suppression, yield reduction and alteration in microbial community. Metal polluted soils have become a major concern for scientists around the globe. In more recent times, armed with new knowledge and understanding, removal of heavy metals using different applications has emerged as a solution for waste treatment and contaminant remediation in water and soil. However, the description of metal toxicity to the plants and its removal and degradation from the soil is limited. There are a number of reports in the literature where PGP bacterial inoculation and various chelating agents improves metal accumulation and it’s detoxification in different plant parts without influencing plant growth. Therefore, there is a need to select some useful chemicals which possess the potential to improve plant growth as well as expedite the phytoremediation of metals. In this review, we have discussed the mechanisms possessed by different chelating agents to promote plant growth and phytoremediation of metals. We anticipate that this analysis of interconnected systems will lead to the discovery of new research fields.
