Key facts

  • Rajasthan soils are grouped by NBSS&LUP into Entisols, Inceptisols, Aridisols, Vertisols and Alfisols, with Entisols forming the largest share.
  • Western sandy arid soils dominate districts such as Jaisalmer, Bikaner, Barmer, Churu, Jodhpur and Nagaur and are low in organic matter and moisture.
  • CAZRI at Jodhpur is linked with arid soil-water management, dune stabilisation, shelterbelts, rangelands and desertification control.
  • Eastern alluvial soils of the Banas-Chambal side support crops such as wheat, mustard, gram, bajra and pockets of sugarcane.
  • Hadoti black soils in Kota, Bundi, Baran and Jhalawar are clayey, moisture-retentive Vertisols suited to soybean, wheat, mustard, coriander and garlic...

  6. 6

    Southern red-loamy soils in Banswara, Dungarpur, Pratapgarh and nearby Aravalli areas derive their red colour from iron oxides in crystalline rocks.

  7. 7

    Saline-alkaline soils around Sambhar, Didwana, Pachpadra and the Luni tract result from aridity, evaporation, weak drainage and salt accumulation.

  8. 8

    Watershed treatment and Soil Health Cards connect Rajasthan soil conservation with runoff control, nutrient diagnosis and location-specific farm advice.

How are Rajasthan's soils classified by area?

Rajasthan's soils are commonly classified into NBSS&LUP soil orders led by Entisols, Inceptisols and Aridisols, while older RAS-style notes also use descriptive groups such as desert, dune, brown, sierozem, red-loam, hill, saline-sodic, alluvial and black soils. Rajasthan Forest Department manual citing NBSS&LUP classifies Rajasthan soils into five orders. Older exam-use groups are also used for descriptive questions. According to Rajasthan Economic Review 2025-26, Rajasthan's geographical area is 3.42 lakh sq. km.

Soil orderShare of total area
Entisolsabout 36 percent
Inceptisolsabout 23 percent
Aridisolsabout 20 percent
Vertisolsabout 2 percent
Alfisolsbelow 1 percent

Older exam-use groups

  • Desert/sandy soils
  • Dunes and associated soils
  • Brown soils
  • Sierozems
  • Red loams
  • Hill soils
  • Saline-sodic soils
  • Alluvial and black soils
