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.

The districts of Jaisalmer, Bikaner, Barmer, Jalor, Jodhpur, Ganganagar, Sirohi, Jhunjhunu, Pali and Sikar have alkaline and saline soils with a calcareous base. There is some nitrate concentration in the soil of these regions. TheJaisalmer region has Aeolian sand that varies from sandy to sandy loam. In fact Jaisalmer is renowned for its sandstone.
