Based on the solution of simplified difference method for infiltration equation in unsaturated soil, we have constructed the non-time difference variant implicit scheme. The deepness of water in the soil is the function of conductivity and sorptivity of water. For the purpose to reduce the errors in the moisture coefficients calculation, we must use implicit difference scheme. As a result, we have given the moisture profiles for Yolo Light Clay and Silt Loam in two ways of calculation in this paper.
