Impenetrable caliche layers restrict water movement. Water applied to the soil can not move into or through soil with a tight caliche layer. Water perched on top of the caliche can contribute to problems associated with inadequate root aeration. In addition, soils with poor drainage due to the presence of caliche will have a tendency toAlong the river bottoms across the area and the broad plains to the southeast of Austin the soils are often deep sandy loams.
