Abstract: Phytic acid or phytate (myo-inositol hexakisphosphate), a kind of organic phosphorus (P_o), is an important P pool in soils, accounting for 50%-80% of P_o and 20%-50% of total P. However, phytate contains 6 phosphate groups, which has strong complexing ability and is readily being adsorbed by soil solid matrix (goethite, hematite, and boehmite) to form poorly-soluble or insoluble complexes, resulting in low bioavailability. The formation and stability of phytate-mineral complexes determines the mobilization and utilization efficiency of phytate, which is influenced by various factors including phytate concentration, pH, temperature, complexation ways, number of phosphate groups participated in coordination, adsorption affinity, and soil mineral types. Plant roots and microorganisms secrete organic acids like citrate and oxalate, which can release phytate and mineral elements from the complexes via competitive adsorption, complexation and dissolution. The improved bioavailability of phytate-P and mineral elements helps to reduce exogenous P fertilizer application and P pollution risk, which is of great environmental and practical importance. Therefore, this paper reviews phytate-mineral complexes formation process and the associated influencing factors (phytate concentration, pH and temperature) and complexes stability and the associated influencing factors (adsorption mode and mineral species). In addition, the efficiency and mechanism of organic acids-mediated mobilization of phytate-mineral complexes (ligand exchange, competitive adsorption, hydrogen bonding and dissolution) and the associated influencing factors (complexes type and stability, phytate adsorption density, organic acid species and concentration, and pH) were illustrated. The information helps to provide theoretical and technical supports to improve the bioavailability and utilization of soil endogenous phytate-P.
