Q1. Consider the following statements about old soil classification in Rajasthan: 1. The old classification groups Rajasthan soils into eight categories. 2. The eight categories include desert/sandy soils, dunes and associated soils, brown soils, sierozems, red loams, hill soils, saline-sodic soils, and alluvial and black soils. 3. Sierozems occur on both sides of the Aravalli Hills in districts such as Pali, Nagaur, Ajmer, Jaipur and Dausa. 4. The old classification excludes saline-sodic soils because they are not natural soils of Rajasthan. Which of the statements given above are correct?
Explanation
Statements 1, 2 and 3 are correct as per the Rajasthan Forest Department manual. Statement 4 is false because saline-sodic soils are explicitly one of the eight old-classification groups, and the manual also locates them in natural depressions such as Sambhar and Pachpadra.
