Based on this, we suggest an universal equation for the relative gas diffusivity (Dp/Do, where Do is the gas diffusion coefficient in free air) as a function of soil-air content, The new gas diffusivity equation with given parameter values is shown to unify a most of the existing, predictive Dp/Do models.
