Salidic Haplocalcid and landscape AE

A Salidic Haplocalcid from the interior of the UAE.

 

Salidic Haplocalcids are the Haplocalcids that have an ECe of more than 8 to less than 30 dS m −1 in a layer 10 cm or more thick, within 100 cm of the soil surface (UAE Keys to Soil Taxonomy). The "salidic" subgroup in Haplocalcids is not currently recognized in Soil Taxonomy.

 

Haplocalcids are the Calcids that have a calcic horizon with its upper boundary within 100 cm of the soil surface. These soils do not have a duripan or an argillic, natric, or petrocalcic horizon within 100 cm of the soil surface. Some of the soils have a cambic horizon above the calcic horizon. Haplocalcids are extensive.

 

Calcids are the Aridisols with calcium carbonate that was in the parent materials or was added as dust, or both. Precipitation is insufficient to leach or even move the carbonates to great depths. The upper boundary of the calcic or petrocalcic horizon is normally within 50 cm of the soil surface. If the soils are irrigated and cultivated, micronutrient deficiencies are normal. These soils are extensive in the western part of the United States and in other arid regions of the world.
