%X In this paper, a solute moving equation in the nonstick soil water is studied. The existence and uniqueness of its generalized solutions and discrete mixed finite element(MFE) solutions are proved, and the error estimates of the discrete MFE solutions are analyzed. And finally, a numerical example is given. By using the MFE methods, the solute density and flux can be simulated meanwhile; moreover, the computational accuracy for solute flux is high and numerical model is stable.
