Which of the following statements with reference to saline soil in India is/are correct? Select the answer using the code given below :
2 only
Incorrect
Saline soils are not rich in nitrogen.
In fact, they generally lack essential nutrients, especially nitrogen and calcium.
Their fertility is low due to high concentration of soluble salts, which hinders plant growth.
Correct
Saline soils are commonly found in:
Arid and semi-arid regions (e.g., Rajasthan, Gujarat) due to poor drainage and high evaporation.
Waterlogged and swampy areas (e.g., parts of Uttar Pradesh, West Bengal), where improper irrigation leads to salt accumulation on the surface.
Which of the following statements with reference to Humus is/are correct ?
Select the answer using the code given below :
The soil that is present over the piedmont plains such as Chos and Duars is
Which of the following statements regarding Soil is/are FALSE?
1. Fertile soil supports plant growth by providing plants with nutrients, acting as a water holding body and serving as the substrate to which plants anchor their roots.
2. Vegetation, tree cover and forest prevents soil degradation and desertification by stabilizing the soil, maintaining water and nutrient cycling.
3. Grass found on pasture lands cannot protect the soil against soil erosion and also inhibits the soil biological activities.

With reference to the different types of soil found in India, identify the pairs which is/are wrongly matched.
1. Submontane soil - These are formed by the deposition of eroded material and are found in the Tarai region stretching from Jammu and Kashmir to Assam.
2. Karewa soil - These are the lacustrine deposits found in the Kashmir valleys and Bhadarwah Valley.
3. Peaty and Marshy soil - These are typical soils of the monsoon climate characterised by seasonal rainfall and is deficient in organic matter.
4. Laterite soil - These soils are rich in humus and organic matter.
Choose the correct answer from the options given below:
Match List I with List II.
| List – I (Pedogenic Process) | List – II (Description) |
|---|---|
| A. Podzolization | I. It is associated with humid cold mid-latitude climates and coniferous vegetation |
| B. Laterization | II. It is associated with soils found in tropical and subtropical environments |
| C. Calcification | III. It is associated with warm, semi-arid environments, usually in grassland vegetation where evapotranspiration exceeds precipitation |
| D. Gleization | IV. It is associated with poorly drained and water logged areas of cold climates and peat is found in the upper portion of the soil |
