Detailed explanation-1: -Desert soil is found majorly in north-west India, especially in the state of Rajasthan. This is due to the Thar desert that covers the state.
Detailed explanation-2: -The largest area in Rajasthan is occupied by desert soil, which covers the area west of the Aravallis up to the Pakistan border. The entire area is ill watered and unproductive and characterized with sand dunes, hillocks and rock outcrops. The soils contain about 90 to 95 per cent sand and about 5 to 7 per cent clay.
Detailed explanation-3: -The types of soil available in Rajasthan are mostly sandy, saline, alkaline and chalky (calcareous). Clay, loamy, black lava soil and nitrogenous soils are also found.
Detailed explanation-4: -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.
Detailed explanation-5: -Desert soils (Aridisols) occupy about 12% of the Earth’s ice-free land surface, and 8% of the United States land area, all in the western states: Texas, New Mexico, Colorado, Wyoming, Montana, Arizona, Utah, Nevada, Idaho, California, Oregon, and Washington.
