From Salt‐Affected Marginal Land Resource to Remediation Agent: Halophyte‐Derived Biochar for Ameliorating Cd‐Contaminated Acidic Soil

Land Degradation &Development, Volume 37, Issue 15, Page 10824-10834, September 2026.
ABSTRACT Cadmium (Cd) contamination of acidic soils poses a significant threat to ecosystem stability and crop health. This study evaluated the potential of biochar derived from the halophyte Salicornia europaea (SBC), a salt‐tolerant plant that grows on saline‐alkali marginal land, to remediate Cd‐contaminated acidic soil.
