HAPLOSALID, TYPIC
Haplosalids are the Aridisols that have a salic horizon within 100 cm of the soil surface. In the UAE Soil Taxonomy system, phases of soil taxa have been developed for those mineral soils that have soil properties or characteristics that occur at a deeper depth than currently identified for an established taxonomic subgroup (typically deeper than one meter) or soil properties that effect interpretations not currently recognized at the subgroup level. The phases which have been identified in the UAE include: anhydritic, aquic, calcic, gypsic, lithic, petrocalcic, petrogypsic, salic, salidic, shelly, and sodic.
Soil profile: A representative soil profile of a Haplosalid in the United Arab Emirates (UAE). (Typic Haplosalids, gypsic-aquic)
Landscape: A sabkha a few miles inland from the northern coast of the UAE.
Soil Feature: Gypsum crystal. (The small voids in the lower subsoil are a result of the removal of gypsum crystals.)
Phases are added to the family classification separated by a comma (Typic Torripsamments, carbonatic, hyperthermic, salic). If more than one contrasting phase is needed, the phases are separated by a hyphen and listed in the same order as the Key (Typic Torripsamments, carbonatic, hyperthermic, lithic-salidic). Rarely are more than two phases used.
Aquic: mineral soils that have, at a depth of 100–200 cm from the soil surface saturation with water in one or more layers for 1 month or more in normal years.
Gypsic: Mineral soils that have, at a depth of 100–200 cm from the soil surface a gypsic horizon.
