Biochar (BC) was produced by pyrolyzing the date palm leaf waste at 600 C and then loaded with phosphorus (P) via sorption process. Greenhouse pot experiment was conducted to investigate the application effects of BC and P-loaded biochar (BCP) on growth and availability of P and heavy metals to maize (Zea mays L.) plants grown in contaminated mining soil. The treatments consisted of BC and BCP (at application rates of 5, 10, 20, and 30 g kg-1 of soil), recommended NK and NPK, and a control (no amendment).
