AD105 Typic Haplocalcids
Typic Haplocalcids, sandy-skeletal, mixed, hyperthermic (Soil AD105) are sandy with greater than 35% coarse fragments and with a marginal calcic horizon occurring in the subsoil. They occur on almost level deflation plains and pediments predominantly in eastern parts of the Emirate. They are typically well drained or somewhat excessively drained and have rapid or very rapid permeability. The high gravel contents of these soils limit their suitability for irrigated agriculture.
These soils remain as barren land or in some places are used for low intensity grazing by camel, sheep or goats. They frequently have less than 5% vegetation cover of Cornulaca arabica, Cornulaca monacantha, Cyperus conglomeratus, Dipterygium glaucum, Haloxylon salicornicum, Prosopis cineraria, Tribulus omanense or Zygophyllum spp.
These soils are confined to eastern parts of the Emirate where they occur on pediments and plains associated with rock outcrops. The soil has been identified as a component of one map unit occurring east of Jabal Hafit.
