Gas diffusion ratio in the soil in compare to diffusion in the atmosphere (DP/D0) and air permeability in the soil (Ka) is a function of soil physical characteristic, including pore size, continuity and air porosity.The results showed that with increase in soil moisture and Se, DP/D0 and Ka decreased as a logarithmic function. Maximum and minimum value are obtained, at low and high humidity (near saturation), respectively
