Soils of Rajasthan MCQ - Practice Questions with Answers

Entisols are young, weakly developed soils with little profile formation. In Rajasthan, they are mainly associated with the western arid and desert tract, where wind-blown sand, low rainfall and sparse vegetation limit soil development. The southern part has more red and mixed hill soils, not the typical Entisol belt. The south-eastern region is better known for black and alluvial soils linked with the plateau and river basins. The eastern plains have more alluvial and loamy soils. Therefore, the western part fits the soil setting asked in the question.

In Rajasthan’s soil classification, Inceptisols occur in districts such as Pali, Bhilwara and Sirohi, so that district group matches the question. Kota, Bundi and Baran are more strongly associated with the south-eastern plateau and black-soil belt. Jaipur, Dausa and Alwar fall in the north-eastern and eastern Rajasthan setting, where the soil profile differs from the asked group. Jaisalmer, Barmer and Bikaner belong to the western desert tract, where arid desert soils dominate rather than the Inceptisol group asked here.

Both statements are correct. Red-yellow soil in Rajasthan is found in parts of Sawai Madhopur, Sirohi, Rajsamand, Udaipur and Bhilwara districts. It is also described as suitable for groundnut and cotton cultivation. Therefore, the correct answer is A.

Desert soil is mainly associated with western Rajasthan, especially the arid Thar region, so the statement placing it in eastern Rajasthan is the most incorrect. Wind movement is a normal feature of sandy desert soil, so that statement is not incorrect. Low fertility and comparatively higher salinity are also typical features. Ber, drumstick and karonda are hardy plants often linked with dryland and soil-improvement practices, so that statement is not the best incorrect choice. The geographic location makes eastern Rajasthan the clear error.

Alluvial soil in Rajasthan is mainly associated with the eastern plain, especially areas influenced by river deposits such as Bharatpur and Dholpur. These districts lie in the alluvial belt formed by the Chambal, Banganga and related drainage systems. Banswara-Dungarpur is better known for hilly tribal terrain and red-yellow soils. Kota-Bundi belongs to the south-eastern plateau zone, where black and mixed soils are more prominent. Bikaner-Jaisalmer lies in the western desert, where sandy arid soils dominate rather than alluvial deposits.
