Ajman soil series
The Ajman series is a very deep soil formed in eolian sands. (NE009) UAE.
Taxonomic classification: Typic Torriorthents, coarse-loamy, carbonatic, hyperthermic
Diagnostic subsurface horizon described in this profile is: None. Due to the finely stratified nature of the horizons and lack of structure, this soil does not have a cambic horizon. The slight variations in chroma between horizons is due to the nature of the parent material. Also, the predominance of very fine sand texture prevents this soil from being classified as a Psamment.
The particle-size control section is dominated by very fine sand textures. Some of the sands consist of pieces of shell fragments. The pH (1:1) ranges from 7.2 to 8.4 throughout the profile. Most horizons have EC (1:1) values ranging from about 0.15 to 2.0, but in some places, especially in relatively low-lying positions where a water table may be present slightly below 200 cm, EC (1:1) values range from 2 to 10. Shell fragments larger than 2mm range from 0 to about 10% in individual horizons.
The A horizon is generally about 20 cm thick but ranges from 10 to 25 cm. Hue is 10YR or 2.5Y, value is 5 to 7, and chroma is 2 to 4. Texture is very fine sand, loamy very fine sand, or loamy fine sand.
The C horizons have hue of 10YR or 2.5 Y, value of 5 to 8, and chroma 2 to 4. Texture of the particle-size control section is dominantly very fine sand, but layers may also be fine sand or loamy fine sand. It is finely stratified and, in some pedons, cross-bedded due to the eolian origin.
