Ras Al Khaimah soil series
The Ras Al Khaimah series is a very deep soil formed in loamy alluvial deposits. (NE019).
Taxonomic classification: Typic Haplocambids, coarse-silty, carbonatic, hyperthermic
Diagnostic subsurface horizon described in this profile is: Cambic horizon 10 to 200 cm.
The pH (1:1) ranges from 7.0 to 8.3 throughout the profile. The EC (1:1) is generally less than 1 dS/m in all horizons, but ranges to 3.0. EC (1:1) may be higher in some areas that have been irrigated. Most pedons have a deflation gravel lag on the surface covering 2 to 10% of the area. Gravel content is mostly 0 to 5% throughout the profile, but some pedons have layers with up to 65% gravel below depths of 100 cm.
The A horizon ranges from about 10 to 20 cm thick. It has hue of 10YR, value of 5 or 6, and chroma of 3 or 4. Texture is fine sandy loam, very fine sandy loam, or loam.
The B horizon commonly extends to more than 200 cm in most pedons, but may be underlain by a C horizon at depths of between 100 and 200 cm. Hue is 10YR, value is 4 to 6, and chroma is 3 to 6. Texture is very fine sandy loam, loam, or silt loam.
Where encountered, the C horizon has hue of 10YR, value 5 or 6, and chroma 3 or 4. It is gravelly to extremely gravelly loamy sand or sandy loam.
