Fig. 5.3 Lithic Haplocalcid (AD201)
Taxonomic classification: Lithic Haplocalcids, sandy, mixed, hyperthermic
The Sha’bbiyat series is a shallow sandy soil overlying bedrock (usually calcareous sandstone but occasionally siltstone or similar). The soils are typically well to excessively drained. They occur on flats and gentle slopes within gently undulating deflation plains. They are formed from eolian sands and occur in older landscapes.
These soils are used for rangeland grazing of camels though vegetation cover is frequently less than 5%. Common vegetation species recorded include Haloxylon salicornicum and Zygophyllum spp.
This soil has predominantly been described in the south-west of the Ghayathi sub-area together with scattered sites in the Al Ain sub-area.
The main feature of this soil is the shallow depth (<50cm) to a lithic contact. The soil shows evidence of the accumulation of carbonates, is non-saline and non-gypsic. The shallow depth to the hardpan layer is the main restriction for this soil. This restricts water movement and presents a barrier to root development further restricting the availability of nutrients. Because of this shallow depth the soil is considered unsuitable for irrigated agriculture.
