Calciorthid

Calciorthid is the taxonomic classification of soils possessing the following properties:

• Yellowish to grey colour. (The overall grey colour reflects the deficiency of organic matter) ^[1]
• Poor in nitrogen, phosphorus and potash ^[2]
• Is alkaline, with pH ranging from 7.8 to 8.5. ^[3]
• Are sandy loam to silt in mixture ^[4]

In the U.S. Soil Taxonomy, they fall under the Aridisols (dry soils) and are distinguished by a calcic horizon where calcium carbonate has accumulated. ^[5]
