Abstract:
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
