Fragipan subsoil layers of high bulk density. Alternatively, a fragipan (L. fragilis, brittle meaning brittle pan) is a loamy or, uncommonly, a sandy subsurface horizon which may underlie an albic, argillic, cambic, or spodic horizon. These are brittle when moist, but very hard when dry. They do not soften on wetting, but can be broken in the hands. They designate a genetically developed horizon that has a combination of firmness, brittleness or high bulk density in B and C-horizons. Fragipan character is symbolically expressed by 'x';. Some part of the layer is physically root-restrictive. Fragipan is an epipedon generally found in Terrace Soils of Bangladesh. [Md Mizanur Rahman Bhuiyan]
