On the presentation of Mn-P fixation, this paper reviews the latest advances in recent 10 years and concentrates on the mechanism of phosphorus fixation in acid soils. In addition, it brakes through the classical inorganic P fractionation in to Fe-P, Al-P, O-P and Ca-Pin the traditional P classification and considers Mn-P as one of the main phosphorus fixation modes in latosols, cultivated from the parent basalt material. Furthermore, fixation of P by Fe, Al, Mn is compared, and differentiation from chemical availability and bioavailability of P discussed. Based on the above, this paper presents some alienable measures for enhancing P utilization efficiency and postulates pivotal future research directions in the field of P fixation.
