What is aridisoils made of?

Aridisols are a soil order characterized by their dryness, typically found in arid and semi-arid regions. They are composed mainly of coarse-textured materials, such as sand and silt, and often contain significant amounts of minerals like calcium carbonate and gypsum. Due to limited moisture, organic matter is usually low, and these soils may exhibit salinity and alkalinity. Aridisols are crucial for understanding desert ecosystems and managing land for agriculture and conservation.
