It is usually measured by the depth (in mm) of the water layer that can enter the soil in one hour. An infiltration rate of 15 mm/hour means that a water layer of 15 mm on the soil surface, will take one hour to infiltrate. In dry soil, water infiltrates rapidly.

This helps water. get in more easily, and also breaks up the. crust that often forms and makes water run. off the surface, rather than soak in.
