Phosphorus-iron modified biochar reduces soil salinity and enhances carbon sequestration via calcium-sodium exchange and the reverse stimulation of iron-driven functional microbial taxa.

This study hypothesized that phosphorus-iron (P-Fe) modification improves the pore structure and surface chemical properties of biochar, thereby enhancing its adsorption capacity for salt ions and CO2. When incorporated into saline-alkali soil, this modification improves soil fertility and enriches beneficial microbiot...
