CBSE Class X Social Science LA (5 Marks)

Answer 1

Distribution: Arid soils are one of the most prevalent soil orders of the world.Climate: Arid soils are most characterized by their water deficiencies. Most arid soils contain sufficient amounts of water to support plant growth for no more than 90 consecutive days.Mineralogy: Arid soils typically contain high levels of calcium carbonates, gypsum, as well as sodium.During soil formation, soluble salts at translocated to a subsurface horizon. However, since there is insufficient rainfall to leach salts from the soil profile, soluble salts accumulate.Aridisols often have a surface horizon that is pale in color and low in organic matter.Fertility: Due to limited moisture and accumulated soluble salts, these soils are generally not suited for major crop production. However, if properly managed and irrigated, these soil may become productive. There are notable soils in Maui that are classified as arid soils, but are notable for their unique fertility.
