Calotropis Leaf Extract-Assisted Phytoextraction of Nickel Contaminated Soils

Key Points

• Nickel levels decreased during phytoextraction, indicating effective remediation of contaminated soils.
• A reduction of over 50% in nickel concentration was achieved using Calotropis leaf extract.
• Assessment using observational analysis across multiple contaminated soil sites shows consistent improvement.
• This approach may enable sustainable strategies for heavy metal remediation in agricultural settings.
