The amelioration effect and mechanism of Calcium-Iron modified Biochar on coastal Saline-Alkali soil

Key Points

• Calcium-iron modified biochar significantly improves soil properties and nutrient availability in saline-alkali conditions.
• The study indicates an increase in organic matter content and nutrient retention by over 30% with the use of biochar.
• Assessment using soil chemistry analysis demonstrates the biochemical mechanisms behind the amelioration effect.
• Findings highlight the potential for using biochar to mitigate salinity issues, emphasizing the need for broader application in coastal regions.
