The results show that the SI value of MAP is the logarithmic function of the mass concentration of P, of ammonium N and of Mg, respectively, and increases with the increase of the mass concentration of each element, The SI value of MAP is a polynomial function of the solution pH value, and the optimum pH value for the crystallization of MAP is 9.0 and increases slightly with the increase of N/P. Moreover, the SI value of MAP is a power law function of the solution ionic strength but decreases with its increase.
