Aridisol and Inceptisol, to 18 common crops belong to six groups, i.e. Inceptisols: In Inceptisols, the beginning of soil profile development is evident, but the well-defined profile characteristics of soils thought to be more mature have not yet developed. ARIDISOL Very Dry. Soil structure is weak and the volcanic ash particles are mostly silt- and sand-sized, making these soils highly susceptible to wind erosion. This is a well-developed soil in a temperate environment Soil Profile 4. The soil has good drainage, with moderately rapid permeability and medium runoff. [1] Aridisols (from the Latin aridus, for "dry", and solum) form in an arid or semi-arid climate.Aridisols dominate the deserts and xeric shrublands, which occupy about one third of the Earth's land surface.Aridisols have a very low concentration of organic matter, reflecting the paucity of vegetative production on these dry . Alfisols (Photos 2.1, 2.2 and 2.3) Alfisols are characterized by an Argillic endopedon (subsurface horizon—in this case a Bt genetic horizon) and also by a base saturation greater than 35 %. Other than arid soil (belongs to Aridisol), three extra processes are prominent in subhumid and semiarid soils such as (1) pedoturbation or soil churning is responsible for the formation of Vertisol, (2) argillation or clay migration that forms Alfisol, and (3) melanization responsible for the formation of Mollisol (Kabata-Pendias, 2003; ; The top layer of the soil is red and the horizon below is yellowish. Your description should include the color and nutrient content. Also incorporate calcareous sub-soil and top soil. They have a cryic temperature regime. The availability of soil micronutrients in different soil orders depends upon the soil mineralogy, topography, climatic conditions and cropping sequences.
