Soil Survey of Abu Dhabi Emirate, UAE--Typic Torripsamments consociation, undulating to rolling rises and dunes consists of broad undulating stable sand sheets and gently inclined sand ramps that typically occur on the windward face of north-west - south-east sand ridges. The map unit occurs as scattered, extensive polygons and one large polygon predominantly orientated in a north-west to south-east direction and situated to the north of Liwa. The unit is used as low density grazing. In some areas forestry and farming activities occur. The map unit has a vegetation cover of Cyperus conglomeratus, Haloxylon salicornicum, Zygophyllum spp and Dipterygium glaucum. The map unit forms part of the Cyperetum-Haloxyletum-Zygophylletum vegetation community.
The soils of this map unit are dominated by Typic Torripsamments, mixed, hyperthermic (80% AD158), occupying the dunes and sand sheets. This soil (AD158) covers a vast area within this large map unit and varies significantly in land form. To reflect this, the 80% is split 50:30 between sand sheets of low relief and low slope (typically 2m and 2%) and dunes of high relief and slope (7m and 15%). Other soils include Typic Torripsamments, mixed, hyperthermic, lithic phase (10% AD160), Lithic Torripsamments, mixed, hyperthermic (5% AD153) and Rock Outcrops (5% AD163).
The sandy nature of the soils that limits moisture and nutrient retention is the main constraint to the irrigated agricultural use of this land. Some areas may also be limited by topographic gradient or relative relief.
