A dense, natural subsurface layer of soil whose hardness and relatively slow permeability to water are chiefly due to extreme density or compactness rather than to high clay content(as claypan) or to cementation(as in hardpan). It appears indurated when dry, but shows a moderate to weak brittleness when moist; it contains much silt and sand, but little clay and organic matter. 1, record 3, English, - fragipan
