Abstract

•	MgO and sepiolite doping optimized biochar’s surface properties for phosphorus (P) retention and slow release
•	The potential formation of Mg-PO₄ phases on the optimized biochar surface regulated P retention and release
•	MgO and sepiolite-ptimized biochars increased soil available P by promoting microbial P mineralization and solubilization.
