WebbThe permeability of soil describes how water (or other liquid) and air are able to move through the soil. In the case of rainfall or irrigation, water moves very easily through highly permeable soils and very slowly through soils with low permeability. The permeability of a soil can be determined by calculating its infiltration rate.
