•Addition of HA significantly increased the total loss of clay from soil.•HA had a significant impact on SP and PP loss in kaolinite mixed soil.•Integrated P transport model simulated well temporal variation of clay, P and TOC.•Competitive adsorption of P and HA led to greater loss of SP and PP in r...
