As Sirer soil series
As Sirer soil series (NE006) UAE
The As Sirer series is a very deep soil formed in stratified sandy and loamy alluvial deposits with a thin eolian mantle.
Taxonomic classification: Typic Torriorthents, sandy, mixed, hyperthermic
Diagnostic subsurface horizon described in this profile is: None.
This soil is classified as having a sandy particle-size class, rather than sandy over loamy because the horizon with an overall loamy texture (Ck3 in this typical profile) is stratified with both sandy and loamy textures. Also, the horizon boundary transition is often a bit more than the taxonomic minimum of 12.5 cm thick, and the thickness of the horizon varies in the profile from about 5 cm to 15 cm
Typic Torriorthents are fixed on the driest Torriorthents. Typic Torriorthents are extensive soils in the intermountain States of the United States. Most of them have moderate or strong slopes and are used only for grazing. Others that have gentle slopes are irrigated. The gently sloping soils are mostly on fans or piedmont slopes where the sediments are recent and have little organic carbon.
Some part of the particle-size control section has texture of loamy very fine sand or finer. The pH (1:1) ranges from 7.0 to 8.6 throughout the profile. The EC (1:1) is generally less than 1.0 dS/m in all horizons, but may be higher in some areas that have been irrigated. Most pedons have little or no gravel lag on the surface, but there may be as much as 20% cover of gravel in some places.
The A horizon is generally about 20 cm thick, but ranges from 10 to 25 cm. Hue is 7.5YR or 10YR, value is 4 to 6, and chroma is 3 to 6. Texture is loamy fine sand, very fine sand, or fine sandy loam. As much as 5% fine or medium gravel may be present. A thin layer of loam or silt loam overwash may be present on the surface of some pedons in wadis as a result of brief ponding and sedimentation after heavy rains.
The C horizon has hue of 5YR, 7.5YR, 10YR, or 2.5Y, value of 3 to 7, and chroma of 3 to 6. It is stratified fine sandy loam, loamy very fine sand, loamy fine sand, fine sand, sand, or coarse sand, including gravelly texture modifiers above 100 cm, and gravelly, very gravelly or extremely gravelly texture modifiers below 100 cm. Fine to medium gravel ranges from 0 to 25% in individual horizons above 100 cm and from 0 to 60% below 100 cm.
