Soil Formation Under Desert Pavements

Forming a desert road under a desert road is a common topography in dry areas. They consist of flat or inclined surfaces whose rocks are tightly wrapped in an angular or circular shape and usually show low relief (Mabbutt, 1977). In the arid zone, the pavement forms an alluvial fan and tends to disturb the flow field of the volcano. Soils are commonly found under desert roads and play an important role in pavement development (McFadden et al., 1987). In the past, there were many theories about underground paving and soil development.

Aridisol - A dry soil that is formed under desert conditions with a moisture content of less than 90 days in the growing season and is not leached. They include nearly 12% of the earth's earth. The soil is slowly formed and there is little accumulated organic matter. They may have a basement area of ​​Kalish or Duripan. Many alisoles have a good Bt view, which shows the movement of clay, which was formerly larger. A large group of soil is a subdivision where the type and order of the soil layer divides the soil from other soil. Approximately 185 great organizations are recognized in the United States. Field and soil features characterized by clay expansion - contraction (self - mixing by clay), clay such as temperature and substantial amounts of various salts, iron, humus and hard disk are used as distinguishing features.

These microorganisms have multiple functions in the soil. Jones pointed out that soil microorganisms are important for carbon recovery. Clearly, the soil contains twice as much carbon as the atmosphere. These microorganisms help to bind the carbon in the soil, which helps to maintain the soil structure
