Fragipans are dense, brittle subsoil horizons that appear to be indurated when dry, but the apparent induration disappears upon moistening. They are genetic soil horizons that have developed from many different parent materials. Fragipans have a wide geographic distribution, and they have been found below A-B horizon sequences characteristic of several great soil groups, and as a component of Low Humic Gley profiles. Properties of fragipans are closely related to texture of the soil material and the natural drainage of the soil. Fragipans are generally less permeable to water than the horizons above or below. Root penetration into these pans is very limited.
