INDIAN GEOGRAPHY

Detailed explanation-1: -This soil has clay, silt and sand are the dissolved mineral salts and is called halomorphic soil.

Detailed explanation-2: -Explanation: Desert or Arid Soil: Arid soils range from red to brown in color. They are generally sandy in structure and saline in nature. In some areas, the salt content is so high that common salt is obtained by evaporating the saline water.

Detailed explanation-3: -Desert soil is mostly sandy soil (90–95%) found in low-rainfall regions. It has a low content of nitrogen and organic matter with very high calcium carbonate and phosphate, thus making it infertile. The amount of calcium is 10 times higher in the lower layer than in the topsoil.

Detailed explanation-4: -Soluble salts commonly found in soils are calcium, magnesium, sodium, chloride, sulfate, and bicarbonate. Potassium, ammonium, nitrate, and carbonate are also found, but in smaller quantities.

Detailed explanation-5: -Desert soils are downright unusual! They vary tremendously in texture; many are sandy and gravelly, while others contain layers of sticky clay, or even rock-hard, white limy layers. Desert soils may be gray-colored, brown, or even brick red.
